DESCRIPTION OF CHANGES TO FCC ID. S2ZRTC2400 Changes to main board: No changes were made on the main board to either components or layout. The main board was originally designed with a header to facilitate the future addition of a certified cellular radio module. This Class II Permissive change is to add MaxRad model Z3294 tri-

band antenna to the original grant. This antenna has two rf cables that are permanently attached to the antenna. One rf cable has a reverse SMA connector and connects to the ZigBee radio rf output port. The second rf cable has a standard SMA connector and connects to the cellular radio rf output port. Models: The two configurations of the device (without and with the cellular radio module) are differentiated by model designation. Model RTC2400 is the originally certified configuration without the cellular radio module and model RG2400 is the designation given to the device with the cellular radio module included. OEM cellular radio module: The cellular radio module holds FCC identifier QIPTC63. The module is used as supplied by the module manufacturer with no modifications. Appropriate warnings are included in the RTG2400 user manual to insure that rf exposure and other operational conditions of the original QIPTC63 grant are met.

Manufacturers of the cellular terminal are advised to convey the following safety information to users and operating personnel and to incorporate these guidelines into all manuals supplied with the product. Failure to comply with these precautions violates safety standards of design, manufacture and intended use of the product. Siemens AG assumes no liability for customers failure to comply with these precautions. is forbidden to prevent in an aircraft When in a hospital or other health care facility, observe the restrictions on the use of mobiles. Switch the cellular terminal or mobile off, if instructed to do so by the guidelines posted in sensitive areas. Medical equipment may be sensitive to RF energy. The operation of cardiac pacemakers, other implanted medical equipment and hearing aids can be affected by interference from cellular terminals or mobiles placed close to the device. If in doubt about potential danger, contact the physician or the manufacturer of the device to verify that the equipment is properly shielded. Pacemaker patients are advised to keep their hand-held mobile away from the pacemaker, while it is on. Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it cannot be switched on inadvertently. The operation of wireless appliances interference with communications systems. Failure to observe these instructions may lead to the suspension or denial of cellular services to the offender, legal action, or both. Do not operate the cellular terminal or mobile in the presence of flammable gases or fumes. Switch off the cellular terminal when you are near petrol stations, fuel depots, chemical plants or where blasting operations are in progress. Operation of any electrical equipment in potentially explosive atmospheres can constitute a safety hazard. Your cellular terminal or mobile receives and transmits radio frequency energy while switched on. Remember that interference can occur if it is used close to TV sets, radios, computers or inadequately shielded equipment. Follow any special regulations and always switch off the cellular terminal or mobile wherever forbidden, or when you suspect that it may cause interference or danger. Road safety comes first! Do not use a hand-held cellular terminal or mobile when driving a vehicle, unless it is securely mounted in a holder for speakerphone operation. Before making a call with a hand-held terminal or mobile, park the vehicle. Speakerphones must be installed by qualified personnel. Faulty installation or operation can constitute a safety hazard. TC63_HD_V02.000 Page 16 of 116 08.06.2006 TC63 Hardware Interface Description Confidential / Released s IMPORTANT!

Cellular terminals or mobiles operate using radio signals and cellular networks. Because of this, connection cannot be guaranteed at all times under all conditions. Therefore, you should never rely solely upon any wireless device for essential communications, for example emergency calls. Remember, in order to make or receive calls, the cellular terminal or mobile must be switched on and in a service area with adequate cellular signal strength. Some networks do not allow for emergency calls if certain network services or phone features are in use (e.g. lock functions, fixed dialing etc.). You may need to deactivate those features before you can make an emergency call. Some networks require that a valid SIM card be properly inserted in the cellular terminal or mobile.

Table 5: Overview of operating modes Normal operation GSM / GPRS SLEEP Various power save modes set with AT+CFUN to allow permanent access command. Software is active to minimum extent. If the module was registered to the GSM network in IDLE mode, it is registered and paging with the BTS in SLEEP mode, too. Power saving can be chosen at different levels: The NON-CYCLIC SLEEP mode (AT+CFUN=0) disables the AT interface. The CYCLIC SLEEP modes AT+CFUN=7 and 9 alternatingly activate and deactivate the AT interfaces to all AT commands. Software is active. Once registered to the GSM network, paging with BTS is carried out. The module is ready to send and receive. Connection between two subscribers is in progress. Power consumption depends on network coverage individual settings, such as DTX off/on, FR/EFR/HR, hopping sequences, antenna. Module is ready for GPRS data transfer, but no data is currently sent or received. Power consumption depends on network settings and GPRS configuration (e.g. multislot settings). GPRS data transfer in progress. Power consumption depends on network settings (e.g. power control level), uplink / downlink data rates, GPRS configuration (e.g. used multislot settings) and reduction of maximum output power. GSM IDLE GSM TALK GPRS IDLE GPRS DATA POWER DOWN Normal shutdown after sending the AT^SMSO command. Only a voltage regulator is active for powering the RTC. Software is not active. Interfaces are not accessible. Operating voltage (connected to BATT+) remains applied. TC63_HD_V02.000 Page 24 of 116 08.06.2006 TC63 Hardware Interface Description Confidential / Released s Airplane mode Airplane mode shuts down the radio part of the module, causes the module to log off from the GSM/GPRS network and disables all AT commands whose execution requires a radio connection. Airplane mode can be controlled by using the AT commands AT^SCFG and AT+CALA:

With AT^SCFG=MEopMode/Airplane/OnStart the module can be configured to enter the Airplane mode each time when switched on or reset. The parameter AT^SCFG=MEopMode/Airplane can be used to switch back and forth between Normal mode and Airplane mode any time during operation. Setting an alarm time with AT+CALA followed by AT^SMSO wakes the module up into Airplane mode at the scheduled time. Charge-only mode Limited operation for battery powered applications. Enables charging while module is detached from GSM network. Limited number of AT commands is accessible. Charge-only mode applies when the charger is connected if the module was powered down with AT^SMSO. Normal operation (SLEEP, IDLE, TALK, GPRS IDLE, GPRS DATA) and charging running in parallel. Charge mode changes to Charge-only mode when the module is powered down before charging has been completed. Charge mode during normal operation See Table 11 for the various options proceeding from one mode to another. TC63_HD_V02.000 Page 25 of 116 08.06.2006 TC63 Hardware Interface Description Confidential / Released s Power Supply 3.2 TC63 needs to be connected to a power supply at the B2B connector (5 pins each BATT+

and GND). The power supply of TC63 has to be a single voltage source at BATT+. It must be able to provide the peak current during the uplink transmission. All the key functions for supplying power to the device are handled by the power management section of the analog controller. This IC provides the following features:

Stabilizes the supply voltages for the GSM baseband using low drop linear voltage regulators. Switches the module's power voltages for the power-up and -down procedures. Delivers, across the VEXT pin, a regulated voltage for an external application. This voltage is not available in Power-down mode. SIM switch to provide SIM power supply. 3.2.1 Minimizing Power Losses When designing the power supply for your application please pay specific attention to power losses. Ensure that the input voltage VBATT+ never drops below 3.2V on the TC63 board, not even in a transmit burst where current consumption can rise to typical peaks of 2A. It should be noted that TC63 switches off when exceeding these limits. Any voltage drops that may occur in a transmit burst should not exceed 400mV. The measurement network monitors outburst and inburst values. The drop is the difference of both values. The maximum drop (Dmax) since the last start of the module will be saved. In IDLE and SLEEP mode, the module switches off if the minimum battery voltage (Vbattmin) is reached. Example:

VImin = 3.2V Dmax = 0.4V Vbattmin = VImin + Dmax Vbattmin = 3.2V + 0.4V = 3.6V The best approach to reducing voltage drops is to use a board-to-board connection as recommended, and a low impedance power source. The resistance of the power supply lines on the host board and of a battery pack should also be considered. Note:

If the application design requires an adapter cable between both board-to-board connectors, use a flex cable as short as possible in order to minimize power losses. TC63_HD_V02.000 Page 26 of 116 08.06.2006 TC63 Hardware Interface Description Confidential / Released s Example:

If the length of the flex cable reaches the maximum length of 100mm, this connection may cause, for example, a resistance of 30m in the BATT+ line and 30m in the GND line. As a result, a 2A transmit burst would add up to a total voltage drop of 120mV. Plus, if a battery pack is involved, further losses may occur due to the resistance across the battery lines and the internal resistance of the battery including its protection circuit.

3.2.2 Measuring the Supply Voltage VBATT+

The reference points for measuring the supply voltage VBATT+ on the module are BATT+ and GND, both accessible at a capacitor located close to the board-to-board connector of the module. Reference point GND Figure 4: Position of the reference points BATT+ and GND 3.2.3 Monitoring Power Supply by AT Command To monitor the supply voltage you can also use the AT^SBV command which returns the value related to the reference points BATT+ and GND. The module continuously measures the voltage at intervals depending on the operating mode of the RF interface. The duration of measuring ranges from 0.5s in TALK/DATA mode to 50s when TC63 is in IDLE mode or Limited Service (deregistered). The displayed voltage

(in mV) is averaged over the last measuring period before the AT^SBV command was executed. TC63_HD_V02.000 Page 27 of 116 08.06.2006 TC63 Hardware Interface Description Confidential / Released s Power-Up / Power-Down Scenarios 3.3 In general, be sure not to turn on TC63 while it is beyond the safety limits of voltage and temperature stated in Chapter 5. TC63 would immediately switch off after having started and detected these inappropriate conditions. In extreme cases this can cause permanent damage to the module. 3.3.1 Turn on TC63 TC63 can be started in a variety of ways as described in the following sections:

Hardware driven start-up by IGT line: starts Normal mode or Airplane mode (see Section 3.3.1.1) Section 3.3.1.4) Software controlled reset by AT+CFUN command: starts Normal or Airplane mode (see Hardware driven start-up by VCHARGE line: starts charging algorithm and Charge-only mode (see Section 3.3.1.3) Wake-up from Power-down mode by using RTC interrupt: starts Airplane mode The option whether to start into Normal mode or Airplane mode depends on the settings made with the AT^SCFG command or AT+CALA. With AT+CALA, followed by AT^SMSO the module can be configured to restart into Airplane mode at a scheduled alarm time. Switching back and forth between Normal mode and Airplane mode is possible any time during operation by using the AT^SCFG command. After startup or mode change the following URCs indicate the modules ready state:

SYSSTART indicates that the module has entered Normal mode.

^SYSSTART AIRPLANE MODE indicates that the module has entered Airplane mode.

^SYSSTART CHARGE ONLY MODE indicates that the module has entered the Charge-only mode. These URCs are indicated only if the module is set to a fixed bit rate, i.e. they do not appear if autobauding is enabled (AT+IPR0). Detailed explanations on AT^SCFG, AT+CFUN, AT+CALA, Airplane mode and AT+IPR can be found in [1]. Turn on TC63 Using Ignition Line IGT 3.3.1.1 When the TC63 module is in Power-down mode or Charge-only mode, it can be started to Normal mode or Airplane mode by driving the IGT (ignition) line to ground. This must be accomplished with an open drain/collector driver to avoid current flowing into this pin. The module will start up when both of the following two conditions are met:

The supply voltage applied at BATT+ must be in the operating range. The IGT line needs to be driven low for at least 400ms in Power-down mode or at least 2s in Charge-only mode. When released IGT goes high and causes the module to start. Considering different strategies of host application design the figures below show two approaches to meet this requirement: The example in Figure 5 assumes that IGT is activated after BATT+ has already been applied. The example in Figure 6 assumes that IGT is held low before BATT+ is switched on. In either case, to power on the module, ensure that low state of IGT takes at least 400ms (Power-down mode) or 2s (Charge-only mode) from the moment the voltage at BATT+ is available. For Charge-only mode see also Chapter 3.5.6. TC63_HD_V02.000 Page 28 of 116 08.06.2006 TC63 Hardware Interface Description Confidential / Released s Assertion of CTS indicates that the module is ready to receive data from the host application. In addition, if configured to a fixed bit rate (AT+IPR0), the module will send the URC

^SYSSTART or ^SYSSTART AIRPLANE MODE which notifies the host application that the first AT command can be sent to the module. The duration until this URC is output varies with the SIM card and may take a couple of seconds. Please note that no ^SYSSTART or ^SYSSTART AIRPLANE MODE URC will be generated if autobauding (AT+IPR=0) is enabled. To allow the application to detect the ready state of the module we recommend using hardware flow control which can be set with AT\Q or AT+ICF (see [1] for details). The default setting of TC63 is AT\Q0 (no flow control) which shall be altered to AT\Q3 (RTS/CTS handshake). If the application design does not integrate RTS/CTS lines the host application shall wait at least for the ^SYSSTART or ^SYSSTART AIRPLANE MODE URC. However, if the URCs are neither used (due to autobauding) then the only way of checking the modules ready state is polling. To do so, try to send characters (e.g. at) until the module is responding.

If the IGT line is driven low for less than 400ms the module will, instead of starting up, send only the alert message SHUTDOWN after Illegal PowerUp to the host application. The alert message appears on the serial interfaces ASC0 and ASC1 at a fixed bit rate of 115200bps. If other fixed bit rates or autobauding are set, the URC delivers only undefined characters. The message will not be indicated on the USB interface.

The switching mode is determined by the parameter MEShutdown/OnIgnition of the AT^SCFG command. This approach is useful for application manufacturers who wish to have an ON/OFF switch installed on the host device. By factory default, the ON/OFF switch mode of IGT is disabled:

at^scfg=meshutdown/onignition

^SCFG: "MEShutdown/OnIgnition","off"

OK

# Query the current status of IGT.

# IGT can be used only to switch on TC63. IGT works as described in section 3.3.1.1. To configure IGT for use as ON/OFF switch:

at^scfg=meshutdown/onignition,on

^SCFG: "MEShutdown/OnIgnition","on"

OK

# Enable the ON/OFF switch mode of IGT.

# IGT can be used to switch on and off TC63. We strongly recommend taking great care before changing the switching mode of the IGT line. To ensure that the IGT line works properly as ON/OFF switch it is of vital importance that the following conditions are met. Switch-on condition: If the TC63 is off, the IGT line must be asserted for at least 400ms Switch-off condition: If the TC63 is on, the IGT line must be asserted for at least 1s before before being released. The module switches on after 400ms. being released. The module switches off after the line is released. The switch-off routine is identical with the procedure initiated by AT^SMSO, i.e. the software performs an orderly shutdown as described in section 3.3.3.1. Before switching off the module wait at least 2 seconds after startup. ON OFF

If the charger is connected to the charger input of the external charging circuit and the modules VCHARGE pin while TC63 is off, and the battery voltage is above the undervoltage lockout threshold, processor controlled fast charging starts (see Section 3.5.5). TC63 enters a restricted mode, referred to as Charge-only mode where only the charging algorithm will be launched. During the Charge-only mode TC63 is neither logged on to the GSM network nor are the serial interfaces fully accessible. To switch from Charge-only mode to Normal mode the ignition line (IGT) must be pulled low for at least 2 seconds. When released, the IGT line goes high and causes the module to enter the Normal mode. See also Section 3.5.6. TC63_HD_V02.000 Page 32 of 116 08.06.2006 TC63 Hardware Interface Description Confidential / Released s 3.3.1.4 Reset TC63 via AT+CFUN Command To reset and restart the TC63 module use the command AT+CFUN. You can enter AT+CFUN=,1 or AT+CFUN=x,1, where x may be in the range from 0 to 9. See [1] for details. If configured to a fix baud rate (AT+IPR0), the module will send the URC ^SYSSTART or

^SYSSTART AIRPLANE MODE to notify that it is ready to operate. If autobauding is enabled (AT+IPR=0) there will be no notification. To register to the network SIM PIN authentication is necessary after restart. 3.3.1.5 Reset or Turn off TC63 in Case of Emergency Caution: Use the EMERG_RST pin only when, due to serious problems, the software is not responding for more than 5 seconds. Pulling the EMERG_RST pin causes the loss of all information stored in the volatile memory. Therefore, this procedure is intended only for use in case of emergency, e.g. if TC63 does not respond, if reset or shutdown via AT command fails. The EMERG_RST signal is available on the application interface. To control the EMERG_RST line it is recommended to use an open drain / collector driver. The EMERG_RST line can be used to switch off or to reset the module. In any case the EMERG_RST line must be pulled to ground for 10ms. Then, after releasing the EMERG_RST line the module restarts if IGT is held low for at least 400ms. Otherwise, if IGT is not low the module switches off. In this case, it can be restarted any time as described in section 3.3.1.1. After hardware driven restart, notification via ^SYSSTART or ^SYSSTART AIRPLANE URC is the same as in case of restart by IGT or AT command. To register to the network SIM PIN authentication is necessary after restart. 3.3.1.6 Using EMERG_RST Signal to Reset Application(s) or External Device(s) When the module starts up, while IGT is held low for 400ms, the EMERG_RST signal goes low for 120ms as shown in Figure 5 and Figure 6. During this 120ms period, EMERG_RST becomes an output which can be used to reset application(s) or external device(s) connected to the module. After the 120ms period, i.e. during operation of the module, the EMERG_RST pin is an input. Specifications of the input and output mode of EMERG_RST can be found in Table 26.

As shown in Figure 5 and Figure 6 the pins are in undefined state while the module is initializing. Once the startup initialization has completed, i.e. when CTS is high and the software is running, all pins are in defined state. The state of several pins will change again once the respective interface is activated or configured by AT command.

Normal shutdown: Software controlled by AT^SMSO command Automatic shutdown: Takes effect if board or battery temperature is out of range or if undervoltage or overvoltage conditions occur. Turn off TC63 Using AT Command 3.3.3.1 The best and safest approach to powering down TC63 is to issue the AT^SMSO command. This procedure lets TC63 log off from the network and allows the software to enter into a secure state and safe data before disconnecting the power supply. The mode is referred to as Power-down mode. In this mode, only the RTC stays active. Before switching off the device sends the following response:

After sending AT^SMSO do not enter any other AT commands. There are two ways to verify when the module turns off:

Wait for the URC ^SHUTDOWN. It indicates that data have been stored non-volatile OK

^SHUTDOWN

^SMSO: MS OFF and the module turns off in less than 1 second. Also, you can monitor the PWR_IND pin. High state of PWR_IND definitely indicates that the module is switched off. Be sure not to disconnect the supply voltage VBATT+ before the URC ^SHUTDOWN has been issued and the PWR_IND signal has gone high. Otherwise you run the risk of losing data. Signal states during turn-off are shown in Figure 8. While TC63 is in Power-down mode the application interface is switched off and must not be fed from any other source. Therefore, your application must be designed to avoid any current flow into any digital pins of the application interface, especially of the serial interfaces. No special care is required for the USB interface which is protected from reverse current.

If the supply voltage at BATT+ was disconnected and then applied again without starting up the TC63 module, the leakage current ranges between 90A and 100A. If the TC63 module is started and afterwards powered down with AT^SMSO, then the leakage current is only 50A. Therefore, in order to minimize the leakage current take care to start up the module at least once before it is powered down. TC63_HD_V02.000 Page 36 of 116 08.06.2006 TC63 Hardware Interface Description Confidential / Released s Turn on/off TC63 Applications with Integrated USB 3.3.3.3 In a Windows environment, the USB COM port emulation causes the USB port of TC63 to appear as a virtual COM port (VCOM port). The VCOM port emulation is only present when Windows can communicate with the module, and is lost when the module shuts down. Therefore, the host application or Terminal program must be disconnected from the USB VCOM port each time the module is restarted. Restart after shutdown with AT^SMSO:

After entering the power-down command AT^SMSO on one of the interfaces (ASC0, ASC1, USB) the host application or Terminal program used on the USB VCOM port must be closed before the module is restarted by activating the IGT line. Software reset with AT+CFUN=x,1:

Likewise, when using the reset command AT+CFUN=x,1 on one of the interfaces (ASC0, ASC1, USB) ensure that the host application or Terminal program on the USB VCOM port be closed down before the module restarts. Note that if AT+CFUN=x,1 is entered on the USB interface the application or Terminal program on the USB VCOM port must be closed immediately after the response OK is returned. TC63_HD_V02.000 Page 37 of 116 08.06.2006 TC63 Hardware Interface Description Confidential / Released 3.3.4 Automatic Shutdown s the TC63 board is exceeding the critical limits of overtemperature or undertemperature the battery is exceeding the critical limits of overtemperature or undertemperature Automatic shutdown takes effect if undervoltage or overvoltage is detected See Charge-only mode described in section 3.5.6 for exceptions. The automatic shutdown procedure is equivalent to the Power-down initiated with the AT^SMSO command, i.e. TC63 logs off from the network and the software enters a secure state avoiding loss of data. Alert messages transmitted before the device switches off are implemented as Unsolicited Result Codes (URCs). The URC presentation mode varies with the condition, please see Chapters 3.3.4.1 to 3.3.4.4 for details. For further instructions on AT commands refer to [1]. Thermal Shutdown 3.3.4.1 The board temperature is constantly monitored by an internal NTC resistor located on the PCB. The NTC that detects the battery temperature must be part of the battery pack circuit as described in 3.5.3 The values detected by either NTC resistor are measured directly on the board or the battery and therefore, are not fully identical with the ambient temperature. Each time the board or battery temperature goes out of range or back to normal, TC63 instantly displays an alert (if enabled). URCs indicating the level "1" or "-1" allow the user to take appropriate precautions, such as protecting the module from exposure to extreme conditions. The presentation of the URCs depends on the settings selected with the AT^SCTM write command:

AT^SCTM=1: Presentation of URCs is always enabled. AT^SCTM=0 (default): Presentation of URCs is enabled for 15 seconds time after start-up of TC63. After 15 seconds operation, the presentation will be disabled, i.e. no alert messages can be generated. URCs indicating the level "2" or "-2" are instantly followed by an orderly shutdown. The presentation of these URCs is always enabled, i.e. they will be output even though the factory setting AT^SCTM=0 was never changed. The maximum temperature ratings are stated in Chapter 5.2. Refer to Table 7 for the associated URCs.

Temperature Control during Emergency call 3.3.4.2 If the temperature limit is exceeded while an emergency call is in progress the engine continues to measure the temperature, but deactivates the shutdown functionality. If the temperature is still out of range when the call ends, the module switches off immediately

(without another alert message).

^SBC: Undervoltage. 3.3.4.3 Undervoltage Shutdown if Battery NTC is Present In applications where the modules charging technique is used and an NTC is connected to the BATT_TEMP terminal, the software constantly monitors the applied voltage. If the measured battery voltage is no more sufficient to set up a call the following URC will be presented:

The message will be reported, for example, when you attempt to make a call while the voltage is close to the shutdown threshold of 3.2V and further power loss is caused during the transmit burst. In IDLE mode, the shutdown threshold is the sum of the modules minimum supply voltage (3.2V) and the value of the maximum voltage drop resulting from earlier calls. This means that in IDLE mode the actual shutdown threshold may be higher than 3.2V. Therefore, to properly calculate the actual shutdown threshold application manufacturers are advised to measure the maximum voltage drops that may occur during transmit bursts. To remind the user that the battery needs to be charged soon, the URC appears several times before the module switches off. This type of URC does not need to be activated by the user. It will be output automatically when fault conditions occur. TC63_HD_V02.000 Page 39 of 116 08.06.2006 TC63 Hardware Interface Description Confidential / Released s 3.3.4.4 Undervoltage Shutdown if no Battery NTC is Present The undervoltage protection is also effective in applications, where no NTC connects to the BATT_TEMP terminal. Thus, you can take advantage of this feature even though the application handles the charging process or TC63 is fed by a fixed supply voltage. All you need to do is executing the write command AT^SBC=<current> which automatically enables the presentation of URCs. You do not need to specify <current>. Whenever the supply voltage falls below the value of 3.2V the URC appears several times before the module switches off. This type of URC does not need to be activated by the user. It will be output automatically when fault conditions occur.

^SBC: Undervoltage

^SBC: Overvoltage warning

^SBC: Overvoltage shutdown 3.3.4.5 Overvoltage Shutdown The overvoltage shutdown threshold is 100mV above the maximum supply voltage VBATT+

specified in Table 27. When the supply voltage approaches the overvoltage shutdown threshold the module will send the following URC This alert is sent once. When the overvoltage shutdown threshold is exceeded the module will send the URC before it shuts down cleanly. This type of URC does not need to be activated by the user. It will be output automatically when fault conditions occur. Keep in mind that several TC63 components are directly linked to BATT+ and, therefore, the supply voltage remains applied at major parts of TC63, even if the module is switched off. Especially the power amplifier is very sensitive to high voltage and might even be destroyed. TC63_HD_V02.000 Page 40 of 116 08.06.2006 TC63 Hardware Interface Description Confidential / Released s Automatic GPRS Multislot Class Change from GPRS Multislot Class 12 (4Tx slots) to GPRS Multislot Class 8 (1Tx) from GPRS Multislot Class 10 (2Tx slots) to GPRS Multislot Class 8 (1Tx) 3.4 Temperature control is also effective for operation in GPRS Multislot Class 10 and GPRS Multislot Class 12. If the board temperature rises close to the limit specified for normal operation1 while data are transmitted over GPRS, the module automatically reverts:

This reduces the power consumption and, consequently, causes the boards temperature to decrease. Once the temperature drops by 5 degrees, TC63 returns to the higher Multislot Class. If the temperature stays at the critical level or even continues to rise, TC63 will not switch back to the higher class. After a transition from GPRS Multislot Class 12 or 10 to GPRS Multislot Class 8 a possible switchback to GPRS Multislot Class 12 or 10 is blocked for one minute. Please note that there is not one single cause of switching over to a lower Multislot Class. Rather it is the result of an interaction of several factors, such as the board temperature that depends largely on the ambient temperature, the operating mode and the transmit power. Furthermore, take into account that there is a delay until the network proceeds to a lower or, accordingly, higher Multislot Class. The delay time is network dependent. In extreme cases, if it takes too much time for the network and the temperature cannot drop due to this delay, the module may even switch off as described in Section 3.3.4.1. 1 See Chapter 5.2 for temperature limits. TC63_HD_V02.000 Page 41 of 116 08.06.2006 TC63 Hardware Interface Description Confidential / Released s Charging Control 3.5 TC63 integrates a charging management for rechargeable Lithium Ion and Lithium Polymer batteries. You can skip this chapter if charging is not your concern, or if you are not using the implemented charging algorithm. The following sections contain an overview of charging and battery specifications. Please refer to [4] for greater detail, especially regarding requirements for batteries and chargers, appropriate charging circuits, recommended batteries and an analysis of operational issues typical of battery powered GSM/GPRS applications. 3.5.1 Hardware Requirements TC63 has no on-board charging circuit. To benefit from the implemented charging management you are required to install a charging circuit within your application according to the Figure 44. 3.5.2 Software Requirements Use the command AT^SBC, parameter <current>, to enter the current consumption of the host application. This information enables the TC63 module to correctly determine the end of charging and terminate charging automatically when the battery is fully charged. If the

<current> value is inaccurate and the application draws a current higher than the final charge current, either charging will not be terminated or the battery fails to reach its maximum voltage. Therefore, the termination condition is defined as: current consumption dependent on operating mode of the ME plus current consumption of the external application. If used the current flowing over the VEXT pin of the application interface must be added, too. The parameter <current> is volatile, meaning that the factory default (0mA) is restored each time the module is powered down or reset. Therefore, for better control of charging, it is recommended to enter the value every time the module is started. See [1] for details on AT^SBC. TC63_HD_V02.000 Page 42 of 116 08.06.2006 TC63 Hardware Interface Description Confidential / Released 3.5.3 Battery Pack Requirements s The charging algorithm has been optimized for rechargeable Lithium batteries that meet the characteristics listed below and in Table 8. It is recommended that the battery pack you want to integrate into your TC63 application is compliant with these specifications. This ensures reliable operation, proper charging and, particularly, allows you to monitor the battery capacity using the AT^SBC command. Failure to comply with these specifications might cause AT^SBC to deliver incorrect battery capacity values. Li-Ion or Lithium Polymer battery pack specified for a maximum charging voltage of 4.2V and a recommended capacity of 1000 to 1200mAh. Since charging and discharging largely depend on the battery temperature, the battery pack should include an NTC resistor. If the NTC is not inside the battery it must be in thermal contact with the battery. The NTC resistor must be connected between BATT_TEMP and GND. The B value of the NTC should be in the range: 10k +5% @ 25C, B25/85 = 3423K to B

=3435K 3% (alternatively acceptable: 10k +2% @ 25C, B25/50 = 3370K +3%). Please note that the NTC is indispensable for proper charging, i.e. the charging process will not start if no NTC is present. Ensure that the pack incorporates a protection circuit capable of detecting overvoltage

(protection against overcharging), undervoltage (protection against deep discharging) and overcurrent. Due to the discharge current profile typical of GSM applications, the circuit must be insensitive to pulsed current. On the TC63 module, a built-in measuring circuit constantly monitors the supply voltage. In the event of undervoltage, it causes TC63 to power down. Undervoltage thresholds are specific to the battery pack and must be evaluated for the intended model. When you evaluate undervoltage thresholds, consider both the current consumption of TC63 and of the application circuit. The internal resistance of the battery and the protection should be as low as possible. It is recommended not to exceed 150m, even in extreme conditions at low temperature. The battery cell must be insensitive to rupture, fire and gassing under extreme conditions of temperature and charging (voltage, current). The battery pack must be protected from reverse pole connection. For example, the casing should be designed to prevent the user from mounting the battery in reverse orientation. It is recommended that the battery pack be approved to satisfy the requirements of CE conformity. includes Figure 9 shows the circuit diagram of a typical battery pack design that the protection elements described above.

Output voltage:

Output current:

5.2Volts 0.2V (stabilized voltage) 500mA Chargers with a higher output current are acceptable, but please consider that only 500mA will be applied when a 0.3Ohms shunt resistor is connected between VSENSE and ISENSE. See [4] for further details. the reference charging circuit 3.5.5 Implemented Charging Technique If all requirements listed above are met (appropriate external charging circuit of application, battery pack, charger, AT^SBC settings) then charging is enabled in various stages depending on the battery condition:

Trickle charging:

Trickle Charge current flows over the VCHARGE line. Trickle Charging is done when a charger is present (connected to VCHARGE) and the battery is deeply discharged or has undervoltage. If deeply discharged (Deep Discharge Lockout at VBATT+= <2.5V) the battery is charged with 5mA, in case of undervoltage

(Undervoltage Lockout at VBATT+= 2.53.2V) it is charged with 30mA Software controlled charging:

Controlled over the CHARGEGATE. Temperature conditions: 0C to 45C TC63_HD_V02.000 Page 44 of 116 08.06.2006 TC63 Hardware Interface Description Confidential / Released s Software controlled charging is done when the charger is present (connected to VCHARGE) and the battery voltage is at least above the undervoltage threshold. Software controlled charging passes the following stages:

- Power Ramp: Depending on the discharge level of the battery (i.e. the measured battery voltage VBATT+) the software adjusts the maximum charge current for charging the battery. The duration of power ramp charging is very short (less than 30 seconds).

- Fast Charging: Battery is charged with constant current (approx. 500mA) until the battery voltage reaches 4.2V (approx. 80% of the battery capacity).

- Top-up Charging: The battery is charged with constant voltage of 4.2V at stepwise reducing charge current until full battery capacity is reached. Duration of charging:

TC63 provides two charging timers: a software controlled timer set to 4 hours and a hardware controlled timer set to 4.66 hours.

- The duration of software controlled charging depends on the battery capacity and the level of discharge. Normally, charging stops when the battery is fully charged or, at the latest, when the software timer expires after 4 hours.

- The hardware timer is provided to prevent runaway charging and to stop charging if the software is not responding. The hardware timer will start each time the charger is plugged to the VCHARGE line. 3.5.6 Operating Modes during Charging Of course, the battery can be charged regardless of the engine's operating mode. When the GSM module is in Normal mode (SLEEP, IDLE, TALK, GPRS IDLE or GPRS DATA mode), it remains operational while charging is in progress (provided that sufficient voltage is applied). The charging process during the Normal mode is referred to as Charge mode. If the charger is connected to the charger input of the external charging circuit and the modules VCHARGE pin while TC63 is in Power-down mode, TC63 goes into Charge-only mode. While the charger remains connected it is not possible to switch the module off by using the AT^SMSO command or the automatic shutdown mechanism. Instead the following applies:

If the module is in Normal mode and the charger is connected (Charge mode) the AT^SMSO command causes the module to shut down shortly and then start into the Charge-only mode. In Charge-only mode the AT^SMSO command is not usable. In Charge-only mode the module neither switches off when the battery or the module exceeds the critical limits of overtemperature or undertemperature. In these cases you can only switch the module off by disconnecting the charger. To proceed from Charge-only mode to another operating mode you have the following options, provided that the battery voltage is at least above the undervoltage threshold. To switch from Charge-only mode to Normal mode you have two ways:

- Hardware driven: The ignition line (IGT) must be pulled low for at least 2 seconds. When released, the IGT line goes high and causes the module to enter the Normal mode.

- AT command driven: Set the command AT^SCFG=MEopMode/Airplane,off (please do so although the current status of Airplane mode is already off). The module will enter the Normal mode, indicated by the ^SYSSTART URC. TC63_HD_V02.000 Page 45 of 116 08.06.2006 TC63 Hardware Interface Description Confidential / Released s To switch from Charge-only mode the command AT^SCFG=MEopMode/Airplane,on.

In IDLE and TALK mode, the serial interfaces are accessible. All AT commands can be used to full extent.

NOTE: While trickle charging is in progress, be sure that the host application is switched off. If the application is fed from the trickle charge current the module might be prevented to software controlled charging since the current would not be sufficient. from proceeding TC63_HD_V02.000 Page 47 of 116 08.06.2006 TC63 Hardware Interface Description Confidential / Released 3.6 Power Saving s Intended for power saving, SLEEP mode reduces the functionality of the TC63 to a minimum and thus minimizes the current consumption. Settings can be made using the AT+CFUN command. For details see [1]. SLEEP mode falls in two categories:

NON-CYCLIC SLEEP mode: AT+CFUN = 0 CYCLIC SLEEP modes, AT+CFUN = 7 or 9. The functionality level AT+CFUN=1 is where power saving is switched off. This is the default after startup. NON-CYCLIC SLEEP mode permanently blocks the serial interface. The benefit of the CYCLIC SLEEP mode is that the serial interface remains accessible and that, in intermittent wake-up periods, characters can be sent or received without terminating the selected mode. This allows the TC63 to wake up for the duration of an event and, afterwards, to resume power saving. Please refer to [1] for a summary of all SLEEP modes and the different ways of waking up the module. For CYCLIC SLEEP mode both the TC63 and the application must be configured to use hardware flow control. This is necessary since the CTSx signal is set/reset every 0.9-2.7 seconds in order to indicate to the application when the UART is active. Please refer to [1]

for details on how to configure hardware flow control for the TC63. Note: Although not explicitly stated, all explanations given in this section refer equally to ASC0 and ASC1, and accordingly to CTS0 and CTS1 or RTS0 and RTS1. 3.6.1 Network Dependency of SLEEP modes t = 4.615 ms (TDMA frame duration) * 51 (number of frames) * DRX value. The power saving possibilities of SLEEP modes depend on the network the module is registered in. The paging timing cycle varies with the base station. The duration of a paging interval can be calculated from the following formula:

DRX (Discontinuous Reception) is a value from 2 to 9, resulting in paging intervals from 0.47-2.12 seconds. The DRX value of the base station is assigned by the network operator. In the pauses between listening to paging messages, the module resumes power saving, as shown in Figure 10. Paging Power Saving 0.47-2.12 s Paging Paging Power Saving 0.47-2.12 s Power Saving 0.47-2.12 s Paging Figure 10: Power saving and paging The varying pauses explain the different potential for power saving. The longer the pause the less power is consumed.

In this case the activity time is at least the time set with AT^SCFG="PowerSaver/Mode9/

Timeout",<psm9to> (default 2 seconds). RTSx has to be asserted for at least a dedicated debounce time in order to wake up the ME. The debounce time specifies the minimum time period an RTSx signal has to remain asserted for the signal to be recognized as wake up signal and being processed. The debounce time is defined as 8*4.615 ms (TDMA frame duration) and is used to prevent bouncing or other fluctuations from being recognized as signals. Toggling RTSx while the ME is awake has no effect on the AT interface state, the regular hardware flow control via CTS/RTS is unaffected by this RTSx behaviour.

An alarm function is provided that allows to wake up TC63 to Airplane mode without logging on to the GSM network. In addition, you can use the VDDLP pin on the board-to-board connector to backup the RTC from an external capacitor or a battery (rechargeable or non-chargeable). The capacitor is charged by the BATT+ line of TC63. If the voltage supply at BATT+ is disconnected the RTC can be powered by the capacitor. The size of the capacitor determines the duration of buffering when no voltage is applied to TC63, i.e. the larger the capacitor the longer TC63 will save the date and time. A serial 1k resistor placed on the board next to VDDLP limits the charge current of an empty capacitor or battery. The following figures show various sample configurations.

This is wired to the host interface (board-to-board connector) in order to be connected to an external SIM card holder. Six pins on the board-to-board connector are reserved for the SIM interface. The SIM interface supports 3V and 1.8V SIM cards. Please refer to Table 26 for electrical specifications of the SIM interface lines depending on whether a 3V or 1.8V SIM card is used. The CCIN pin serves to detect whether a tray (with SIM card) is present in the card holder. Using the CCIN pin is mandatory for compliance with the GSM 11.11 recommendation if the mechanical design of the host application enables the user to remove the SIM card during operation. To take advantage of this feature, an appropriate SIM card detect switch is required on the card holder. For example, this is true for the model supplied by Molex, which has been tested to operate with TC63 and is part of the Siemens reference equipment submitted for type approval. See Chapter 8 for Molex ordering numbers. Table 12: Signals of the SIM interface (board-to-board connector) Description Signal CCGND Separate ground connection for SIM card to improve EMC. Be sure to use this ground line for the SIM interface rather than any other ground pin or plane on the module. A design example for grounding the SIM interface is shown in Figure 44. CCCLK Chipcard clock, various clock rates can be set in the baseband processor. CCVCC SIM supply voltage. CCIO CCRST Chipcard reset, provided by baseband processor. CCIN Serial data line, input and output. Input on the baseband processor for detecting a SIM card tray in the holder. If the SIM is removed during operation the SIM interface is shut down immediately to prevent destruction of the SIM. The CCIN pin is active low. The CCIN pin is mandatory for applications that allow the user to remove the SIM card during operation. The CCIN pin is solely intended for use with a SIM card. It must not be used for any other purposes. Failure to comply with this requirement may invalidate the type approval of TC63. The total cable length between the board-to-board connector pins on TC63 and the pins of the external SIM card holder must not exceed 100mm in order to meet the specifications of 3GPP TS 51.010-1 and to satisfy the requirements of EMC compliance. To avoid possible cross-talk from the CCCLK signal to the CCIO signal be careful that both lines are not placed closely next to each other. A useful approach is using the CCGND line to shield the CCIO line from the CCCLK line.

T V.24 protocol DCE signalling. The electrical characteristics do not comply with ITU-T V.28. The significant levels are 0V (for low data bit or active state) and 2.9V (for high data bit or inactive state). For electrical characteristics please refer to Table 26. TC63 is designed for use as a DCE. Based on the conventions for DCE-DTE connections it communicates with the customer application (DTE) using the following signals:

Port TXD @ application sends data to the modules TXD0 signal line Port RXD @ application receives data from the modules RXD0 signal line GSM Module (DCE) Application (DTE) TXD0 RXD0 RTS0 CTS0 DTR0 DSR0 DCD0 RING0 TXD RXD RTS CTS DTR DSR DCD RING Figure 16: Serial interface ASC0 Features Includes the data lines TXD0 and RXD0, the status lines RTS0 and CTS0 and, in addition, the modem control lines DTR0, DSR0, DCD0 and RING0. ASC0 is primarily designed for controlling voice calls, transferring CSD, fax and GPRS data and for controlling the GSM engine with AT commands. Full Multiplex capability allows the interface to be partitioned into three virtual channels, yet with CSD and fax services only available on the first logical channel. Please note that when the ASC0 interface runs in Multiplex mode, ASC1 cannot be used. For more details on Multiplex mode see [5]. The DTR0 signal will only be polled once per second from the internal firmware of TC63. The RING0 signal serves to indicate incoming calls and other types of URCs (Unsolicited Result Code). It can also be used to send pulses to the host application, for example to wake up the application from power saving state. See [1] for details on how to configure the RING0 line by AT^SCFG. By default, configured for 8 data bits, no parity and 1 stop bit. The setting can be changed using the AT command AT+ICF and, if required, AT^STPB. For details see [1]. ASC0 can be operated at bit rates from 300 bps to 460,800 bps. Autobauding supports bit rates from 1,200 bps to 460,800 bps. Autobauding is not compatible with multiplex mode.

As both operating systems use multiple methods to access modem settings this section provides only a brief summary of the most important steps. Take care that the usbmodem.inf file delivered with TC63 is at hand. Connect the USB cable to the TC63 host application (for example the evaluation board DSB75) and the PC. Windows detects TC63 as a new USB modem, opens the Found New Hardware Wizard and reports that it is searching for the Siemens AG WM USB Modem driver. Follow the instructions on the screen and specify the path where the usbmodem.inf file is located. Windows will copy the required software to your computer and configure the modem by assigning a free COM port. If you are already using more than one COM port then the next free one will be allocated. Click Finish to complete the installation. Notes for Windows 2000 only:

During the installation procedure you will be prompted for the usbser.sys driver. Make sure the file is present before you start installing the above inf file. The usbser.sys file is not delivered as a single file, but must be extracted from a Windows 2000 cabinet file. This is either the file driver.cab located in the I386 folder of the original Windows 2000 CD or a later cabinet file inside the Service Pack. SP4 for example includes the sp4.cab file which can be found in its I386 folder. The usbser.sys driver from the Service Pack has priority over one provided with the standard Windows 2000 install CD. It is necessary to restart Windows 2000 to make the changes take effect.

It consists of two lines, the serial data line I2CDAT and the serial clock line I2CCLK. The TC63 module acts as a single master device, e.g. the clock I2CCLK is driven by module. I2CDAT is a bi-directional line. Each device connected to the bus is software addressable by a unique 7-bit address, and simple master/slave relationships exist at all times. The module operates as master-

transmitter or as master-receiver. The customer application transmits or receives data only on request of the module. To configure and activate the I2C interface use the AT^SSPI command described in [1]. To configure and activate the I2C bus use the AT^SSPI command. Detailed information on the AT^SSPI command as well explanations on the protocol and syntax required for data transmission can be found in [1]. The I2C interface can be powered from an external supply or via the VEXT line of TC63. If connected to the VEXT line the I2C interface will be properly shut down when the module enters the Power-down mode. If you prefer to connect the I2C interface to an external power supply, take care that VCC of the application is in the range of VVEXT and that the interface is shut down when the PWR_IND signal goes high. See figures below as well as Section 7 and Figure 44. In the application I2CDAT and I2CCLK lines need to be connected to a positive supply voltage via a pull-up resistor.

Two analog audio interfaces, both with balanced or single-ended inputs/outputs. Serial digital audio interface (DAI) designed for PCM (Pulse Code Modulation). This means you can connect up to three different audio devices, although only one interface can be operated at a time. Using the AT^SAIC command you can easily switch back and forth.

The electrical characteristics of the voiceband part vary with the audio mode. For example, sending and receiving amplification, sidetone paths, noise suppression etc. depend on the selected mode and can be altered with AT commands

(except for mode 1). Both analog audio interfaces can be used to connect headsets with microphones or speakerphones. Headsets can be operated in audio mode 3, speakerphones in audio mode 2. Audio mode 5 can be used for a speech coder without signal pre or post processing. When shipped from factory, all audio parameters of TC63 are set to interface 1 and audio mode 1. This is the default configuration optimized for the Votronic HH-SI-30.3/V1.1/0 handset and used for type approving the Siemens reference configuration. Audio mode 1 has fix parameters which cannot be modified. To adjust the settings of the Votronic handset simply change to another audio mode. TC63_HD_V02.000 Page 62 of 116 08.06.2006 TC63 Hardware Interface Description Confidential / Released 3.14.1 Speech Processing s The speech samples from the ADC or DAI are handled by the DSP of the baseband controller to calculate e.g. amplifications, sidetone, echo cancellation or noise suppression depending on the configuration of the active audio mode. These processed samples are passed to the speech encoder. Received samples from the speech decoder are passed to the DAC or DAI after post processing (frequency response correction, adding sidetone etc.). Full rate, half rate, enhanced full rate, adaptive multi rate (AMR), speech and channel encoding including voice activity detection (VAD) and discontinuous transmission (DTX) and digital GMSK modulation are also performed on the GSM baseband processor. 3.14.2 Microphone Circuit TC63 has two identical analog microphone inputs. There is no on-board microphone supply circuit, except for the internal voltage supply VMIC and the dedicated audio ground line AGND. Both lines are well suited to feed a balanced audio application or a single-ended audio application. The AGND line on the TC63 board is especially provided to achieve best grounding conditions for your audio application. As there is less current flowing than through other GND lines of the module or the application, this solution will avoid hum and buzz problems. While TC63 is in Power-down mode, the input voltage at any MIC pin must not exceed 0.3V relative to AGND (see also section 5.1). In any other operating state the voltage applied to any MIC pin must be in the range of +2.7V to -0.3V, otherwise undervoltage shutdown may be caused. If VMIC is used to generate the MICP-pin bias voltage as shown in the following examples consider that VMIC is switched off (0V) outside a call. Audio signals applied to MICP in this case must not fall below -0.3V. If higher input levels are used especially in the line input configuration the signal level must be limited to 600mVpp outside a call, or AT^SNFM=,1 should be used to switch on VMIC permanently.

The MICNx input is automatically self biased to the MICPx DC level. It is AC coupled via CK to a resistive divider which is used to optimize supply noise cancellation by the differential microphone amplifier in the module. The VMIC voltage should be filtered if gains larger than 20dB are used. The filter can be attached as a simple first order RC-network (RVMIC and CF). This circuit is well suited if the distance between microphone and module is kept short. Due to good grounding the microphone can be easily ESD protected as its housing usually connects to the negative terminal.

While VMIC is switched off, the input voltage at any MIC pin should not exceed 0.25V relative to AGND (see also section 5.1). In this case no bias voltage has to be supplied from the customer circuit to the MIC pin and any signal voltage should be smaller than Vpp = 0.5V. VMIC can be used to generate the MICP-pin bias voltage as shown below. In this case the bias voltage is only applied if VMIC is switched on. Only if VMIC is switched on, voltage applied to any MIC pin can be in the range of 2.4V to 0V. If these limits are exceeded undervoltage shutdown may be caused. Consider that the maximum full scale input voltage is Vpp = 1.6V. The behavior of VMIC can be controlled with the parameter micVccCtl of the AT command AT^SNFM (see [1]):

micVccCtl=2 (default). VMIC is controlled automatically by the module. VMIC is always switched on while the internal audio circuits of the module are active (e.g., during a call). VMIC can be used as indicator for active audio in the module. micVccCtl=1. VMIC is switched on continuously. This setting can be used to supply the microphone in order to use the signal in other customer circuits as well. However, this setting leads to a higher current consumption in SLEEP modes. micVccCtl=0. VMIC is permanently switched off.

The voltage divider between VMIC and AGND is necessary to bias the input amplifier. MICNx is automatically self biased to the MICPx DC level. The VMIC voltage should be filtered if gains larger than 20dB are used. The filter can be attached as a simple first order RC-network (RVMIC and CF). If a high input level and a lower gain are applied the filter is not necessary. Consider that if VMIC is switched off, the signal voltage should be limited to Vpp = 0.5V and any bias voltage must not be applied. Otherwise VMIC can be switched on permanently by using AT^SNFM=,1. In this case the current consumption in SLEEP modes is higher. If desired, MICNx via CK can also be connected to the inverse output of the AC source instead of connecting it to the reference potential for differential line input.

The frequency of the bit clock is 256 kHz. Any edge of this clock deviates less than 100ns (Jitter) from an ideal 256-kHz clock. The frame sync signal (FS) has a frequency of 8kHz and is high for one BITCLK period. Each frame has a duration of 125 s and contains 32 clock cycles. The PCM interface is master for the bit clock and the frame sync signals.

In PCM mode, 16-bit data are transferred in both directions at the same time during the first 16 clock cycles after the frame sync pulse. The duration of a frame sync pulse is one BITCLK period, starting at the rising edge of BITCLK. TXDAI data is shifted out at the next rising edge of BITCLK. The most significant bit is transferred first.

The signal is generated by the SYNC pin. Please note that this pin can adopt three different operating modes which you can select by using the AT^SSYNC command:

the mode AT^SSYNC=0 described below, and the two LED modes AT^SSYNC=1 or AT^SSYNC=2 described in [1] and Section 3.15.2. The first function (factory default AT^SSYNC=0) is recommended if you want your application to use the synchronization signal for better power supply control. Your platform design must be such that the incoming signal accommodates sufficient power supply to the TC63 module if required. This can be achieved by lowering the current drawn from other components installed in your application. The timing of the synchronization signal is shown below. High level of the SYNC pin indicates increased power consumption during transmission. 1 Tx 577 s every 4.616 ms 2 Tx 1154 s every 4.616 ms Transmit burst SYNC signal*) t = 180 s Figure 28: SYNC signal during transmit burst

*) The duration of the SYNC signal is always equal, no matter whether the traffic or the access burst are active. TC63_HD_V02.000 Page 70 of 116 08.06.2006 TC63 Hardware Interface Description Confidential / Released s 3.15.2 Using the SYNC Pin to Control a Status LED As an alternative to generating the synchronization signal, the SYNC pin can be configured to drive a status LED that indicates different operating modes of the TC63 module. To take advantage of this function the LED mode must be activated with the AT^SSYNC command and the LED must be connected to the host application. The connected LED can be operated in two different display modes (AT^SSYNC=1 or AT^SSYNC=2). For details please refer to [1]. Especially in the development and test phase of an application, system integrators are advised to use the LED mode of the SYNC pin in order to evaluate their product design and identify the source of errors. To operate the LED a buffer, e.g. a transistor or gate, must be included in your application. A sample circuit is shown in Figure 29. Power consumption in the LED mode is the same as for the synchronization signal mode. For details see Table 26, SYNC pin. Figure 29: LED Circuit (Example) TC63_HD_V02.000 Page 71 of 116 08.06.2006 TC63 Hardware Interface Description Confidential / Released s 3.15.3 Behavior of the RING0 Line (ASC0 Interface only) The RING0 line is available on the first serial interface ASC0 (see also Chapter 3.10). The signal serves to indicate incoming calls and other types of URCs (Unsolicited Result Code). Although not mandatory for use in a host application, it is strongly suggested that you connect the RING0 line to an interrupt line of your application. In this case, the application can be designed to receive an interrupt when a falling edge on RING0 occurs. This solution is most effective, particularly, for waking up an application from power saving. Note that if the RING0 line is not wired, the application would be required to permanently poll the data and status lines of the serial interface at the expense of a higher current consumption. Therefore, utilizing the RING0 line provides an option to significantly reduce the overall current consumption of your application. The behavior of the RING0 line varies with the type of event:

When a voice/fax/data call comes in the RING0 line goes low for 1s and high for another 4s. Every 5 seconds the ring string is generated and sent over the RXD0 line. If there is a call in progress and call waiting is activated for a connected handset or handsfree device, the RING0 line switches to ground in order to generate acoustic signals that indicate the waiting call. RING0 1s Ring string 4s 4s 1s Ring string 1s Ring string Figure 30: Incoming voice/fax/data call All other types of Unsolicited Result Codes (URCs) also cause the RING0 line to go low, however for 1 second only. RING0 Figure 31: URC transmission 1s URC 3.15.4 PWR_IND Signal PWR_IND notifies the on/off state of the module. High state of PWR_IND indicates that the module is switched off. The state of PWR_IND immediately changes to low when IGT is pulled low. For state detection an external pull-up resistor is required. TC63_HD_V02.000 Page 72 of 116 08.06.2006 TC63 Hardware Interface Description Confidential / Released s Antenna Interface 4 The RF interface has an impedance of 50. TC63 is capable of sustaining a total mismatch at the antenna connector or pad without any damage, even when transmitting at maximum RF power. The external antenna must be matched properly to achieve best performance regarding radiated power, DC-power consumption, modulation accuracy and harmonic suppression. Antenna matching networks are not included on the TC63 PCB and should be placed in the host application. Regarding the return loss TC63 provides the following values in the active band:

Table 16: Return loss in the active band State of module Receive Transmit Return loss of module

> 8dB not applicable Recommended return loss of application

> 12dB

> 12dB The connection of the antenna or other equipment must be decoupled from DC voltage. This is necessary because the antenna connector is DC coupled to ground via an inductor for ESD protection. Antenna Installation 4.1 To suit the physical design of individual applications TC63 offers two alternative approaches to connecting the antenna:

Recommended approach: U.FL-R-SMT antenna connector from Hirose assembled on the component side of the PCB (top view on TC63). See Section 4.3 for details. Antenna pad and grounding plane placed on the bottom side. See Section 4.2. The U.FL-R-SMT connector has been chosen as antenna reference point (ARP) for the Siemens reference equipment submitted to type approve TC63. All RF data specified throughout this manual are related to the ARP. For compliance with the test results of the Siemens type approval you are advised to give priority to the connector, rather than using the antenna pad. IMPORTANT: Both solutions can only be applied alternatively. This means, whenever an antenna is plugged to the Hirose connector, the pad must not be used. Vice versa, if the antenna is connected to the pad, then the Hirose connector must be left empty.

For proper grounding connect the antenna to the ground plane on the bottom of TC63 which must be connected to the ground plane of the application. When you decide to use the antenna pad take into account that the pad has not been intended as antenna reference point (ARP) for the Siemens TC63 type approval. The antenna pad is provided only as an alternative option which can be used, for example, if the recommended Hirose connection does not fit into your antenna design. Also, consider that according to the GSM recommendations TS 45.005 and TS 51.010-01 a 50 connector is mandatory for type approval measurements. This requires GSM devices with an integral antenna to be temporarily equipped with a suitable connector or a low loss RF cable with adapter. Notes on soldering:

To prevent damage to the module and to obtain long-term solder joint properties you are advised to maintain the standards of good engineering practice for soldering. Be sure to solder the antenna core to the pad and the shielding of the coax cable to the ground plane of the module next to the antenna pad. The direction of the cable is not relevant from the electrical point of view. FR4 Gold plated pad TC63 material properties:

See Chapter 3.3.4 for further information about the NTCs for on-board and battery temperature measurement, automatic thermal shutdown and alert messages. When data is transmitted over GPRS the TC63 automatically reverts to a lower Multislot Class if the temperature increases to the limit specified for normal operation and, vice versa, returns to the higher Multislot Class if the temperature is back to normal. For details see Chapter 3.4 Automatic GPRS Multislot Class Change. 4 Restricted operation allows normal mode speech calls or data transmission for limited time until automatic thermal shutdown takes effect. The duration of emergency calls is unlimited because automatic thermal shutdown is deferred until hang up. 5 Due to temperature measurement uncertainty, a tolerance on the stated shutdown thresholds may occur. The possible deviation is in the range of 3C at the overtemperature limit and 5C at the undertemperature limit.

Consequently, it is subject to ESD handling precautions that typically apply to ESD sensitive components. Proper ESD handling and packaging procedures must be applied throughout the processing, handling and operation of any application that incorporates a TC63 module. Special ESD protection provided on TC63:

Antenna interface: one spark discharge line (spark gap) SIM interface: clamp diodes for protection against overvoltage. The remaining ports of TC63 are not accessible to the user of the final product (since they are installed within the device) and therefore, are only protected according to the Human Body Model requirements. TC63 has been tested according to the EN 61000-4-2 standard. The measured values can be gathered from the following table. Table 35: Measured electrostatic values Contact discharge Specification / Requirements ETSI EN 301 489-7 ESD at SIM port ESD at antenna port Human Body Model (Test conditions: 1.5k, 100pF) ESD at USB interface ESD at all other interfaces 4kV 4kV 1kV 1kV Air discharge 8kV 8kV 1kV 1kV Note: Please note that the values may vary with the individual application design.

An efficient approach is to mount the TC63 PCB to a frame, plate, rack or chassis. Fasteners can be M2 screws plus suitable washers, circuit board spacers, or customized screws, clamps, or brackets. In addition, the board-to-board connection can also be utilized to achieve better support. To help you find appropriate spacers a list of selected screws and distance sleeves for 3mm stacking height can be found in Section 9.2. When using the two small holes take care that the screws are inserted with the screw head on the bottom of the TC63 PCB. Screws for the large holes can be inserted from top or bottom. For proper grounding it is strongly recommended to use large ground plane on the bottom of board in addition to the five GND pins of the board-to-board connector. The ground plane may also be used to attach cooling elements, e.g. a heat sink or thermally conductive tape. To prevent mechanical damage, be careful not to force, bend or twist the module. Be sure it is positioned flat against the host device. All the information you need to install an antenna is summarized in Chapter 4. Note that the antenna pad on the bottom of the TC63 PCB must not be influenced by any other PCBs, components or by the housing of the host device. It needs to be surrounded by a restricted space as described in Section 4.1.

Usage of the various host interfaces depends on the desired features of the application. Audio interface 1 demonstrates the balanced connection of microphone and earpiece. This solution is particularly well suited for internal transducers. Audio interface 2 uses an unbalanced microphone and earpiece connection typically found in headset applications. The charging circuit is optimized for the charging stages (trickle charging and software controlled charging) as well as the battery and charger specifications described in Section 3.5. The PWR_IND line is an open collector that needs an external pull-up resistor which connects to the voltage supply VCC C of the microcontroller. Low state of the open collector pulls the PWR_IND signal low and indicates that the TC63 module is active, high level notifies the Power-down mode. If the module is in Power-down mode avoid current flowing from any other source into the module circuit, for example reverse current from high state external control lines. Therefore, the controlling application must be designed to prevent reverse flow. The internal pull-up resistors (Rp) of the I2C interface can be connected to an external power supply or to the VEXT line of TC63. The advantage of this solution is that when the module enters the Power-down mode, the I2C interface is shut down as well. If you prefer to connect an I2C interface to an external power supply, take care that the interface is shut down when the PWR_IND signal goes high in Power-down mode. The EMC measures are best practice recommendations. In fact, an adequate EMC strategy for an individual application is very much determined by the overall layout and, especially, the position of components. For example, mounting the internal acoustic transducers directly on the PCB eliminates the need to use the ferrite beads shown in the sample schematic. However, when connecting cables to the modules interfaces it is strongly recommended to add appropriate ferrite beads for reducing RF radiation. Disclaimer No warranty, either stated or implied, is provided on the sample schematic diagram shown in Figure 44 and the information detailed in this section. As functionality and compliance with national regulations depend to a great amount on the used electronic components and the individual application layout manufacturers are required to ensure adequate design and operating safeguards for their products using TC63 modules.
