(12Mbit/s) compliant. The USB interface is primarily intended for use as command and data in-

terface and for downloading firmware. The external application is responsible for supplying the VUSB_IN line. This line is used for ca-

ble detection only. The USB part (driver and transceiver) is supplied by means of BATT+. This is because ELS81-US is designed as a self-powered device compliant with the Universal Se-

rial Bus Specification Revision 2.01. Module VREG (3V075) lin. reg. SMT USB part1) VBUS DP DN Detection only Host wakeup RS RS BATT+

Application layout should in this case implement a differential impedance of 90 ohms for proper signal integrity. Figure 5: USB circuit To properly connect the module's USB interface to the external application, a USB 2.0 compat-

ible connector and cable or hardware design is required. For more information on the USB re-

lated signals see Table 2. Furthermore, the USB modem driver distributed with ELS81-US needs to be installed. 1. The specification is ready for download on http://www.usb.org/developers/docs/

els81-us_hid_v01.004 Confidential / Preliminary 2017-09-27 Cinterion ELS81-US Hardware Interface Description 2.1 Application Interface 53 2.1.3.1 Reducing Power Consumption Page 25 of 107 While a USB connection is active, the module will never switch into SLEEP mode. Only if the USB interface is in Suspended state or Detached (i.e., VUSB_IN = 0) is the module able to switch into SLEEP mode thereby saving power. There are two possibilities to enable power re-

duction mechanisms:

Recommended implementation of USB Suspend/Resume/Remote Wakeup:

The USB host should be able to bring its USB interface into the Suspended state as described in the Universal Serial Bus Specification Revision 2.01. For this functionality to work, the VUSB_IN line should always be kept enabled. On incoming calls and other events ELS81-US will then generate a Remote Wakeup request to resume the USB host controller. See also [5] (USB Specification Revision 2.0, Section 10.2.7, p.282):

"If USB System wishes to place the bus in the Suspended state, it commands the Host Con-

troller to stop all bus traffic, including SOFs. This causes all USB devices to enter the Sus-

pended state. In this state, the USB System may enable the Host Controller to respond to bus wakeup events. This allows the Host Controller to respond to bus wakeup signaling to restart the host system."

Implementation for legacy USB applications not supporting USB Suspend/Resume:

As an alternative to the regular USB suspend and resume mechanism it is possible to employ the RING0 line to wake up the host application in case of incoming calls or events signalized by URCs while the USB interface is in Detached state (i.e., VUSB_IN = 0). Every wakeup event will force a new USB enumeration. Therefore, the external application has to carefully consider the enumeration timings to avoid loosing any signalled events. For details on this host wakeup functionality see Section 2.1.13.3. To prevent existing data call con-

nections from being disconnected while the USB interface is in detached state (i.e., VUS-

B_IN=0) it is possible to call AT&D0, thus ignoring the status of the DTR line (see also [1]). 1. The specification is ready for download on http://www.usb.org/developers/docs/

The electrical characteristics do not comply with ITU-T V.28. The significant levels are 0V (for low data bit or active state) and 1.8V (for high data bit or inactive state). For electrical characteristics please refer to Table 2. For an illustration of the interface lines startup behavior see Figure 7. ELS81-US 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 Figure 6: 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. 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. Configured for 8 data bits, no parity and 1 stop bit. ASC0 can be operated at fixed bit rates from 1,200bps up to 921,600bps. Autobauding supports bit rates from 1,200bps up to 230,400bps. Supports RTS0/CTS0 hardware flow control. The hardware hand shake line RTS0 has an internal pull down resistor causing a low level signal, if the line is not used and open. Although hardware flow control is recommended, this allows communication by using only RXD and TXD lines. Wake up from SLEEP mode by RTS0 activation (high to low transition; see Section 3.3.2). Note: The ASC0 modem control lines DTR0, DCD0, DSR0 and RING0 are originally available as GPIO lines. If configured as ASC0 lines, these GPIO lines are assigned as follows:

GPIO1 --> DTR0, GPIO2 --> DCD0, GPIO3 --> DSR0 and GPIO24 --> RING0. Also, DSR0 is shared with the SPI_CLK line of the SPI interface and may be configured as such. Configura-

tion is done by AT command (see [1]). The configuration is non-volatile and becomes active after a module restart. els81-us_hid_v01.004 Confidential / Preliminary 2017-09-27 Cinterion ELS81-US Hardware Interface Description 2.1 Application Interface 53 Page 27 of 107 The following figure shows the startup behavior of the asynchronous serial interface ASC0.

Figure 7: ASC0 startup behavior Notes:

During startup the DTR0 signal is driven active low for 500s. It is recommended to provide a 470 serial resistor for the DTR0 line to prevent shorts (high current flow). No data must be sent over the ASC0 interface before the interface is active and ready to re-

ceive data (see Section 3.2.1). An external pull down to ground on the DCD0 line during the startup phase activates a special mode for ELS81-US. In this special mode the AT command interface is not available and the module may therefore no longer behave as expected. els81-us_hid_v01.004 Confidential / Preliminary 2017-09-27 Cinterion ELS81-US Hardware Interface Description 2.1 Application Interface 53 2.1.5 Serial Interface ASC1 Page 28 of 107 Four ELS81-US GPIO lines can be configured as ASC1 interface signals to provide a 4-wire unbalanced, asynchronous modem interface ASC1 conforming to ITU-T V.24 protocol DCE signalling.

This is wired to the host interface in order to be connected to an external SIM card holder. Five pads on the SMT application interface are reserved for the SIM interface. The UICC/SIM/USIM interface supports 3V and 1.8V SIM cards. Please refer to Table 2 for electrical specifications of the UICC/SIM/USIM interface lines depending on whether a 3V or 1.8V SIM card is used. The CCIN signal serves to detect whether a tray (with SIM card) is present in the card holder. 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 op-

erate with ELS81-US and is part of the Gemalto M2M reference equipment submitted for type approval. See Section 7.1 for Molex ordering numbers.

CCIO CCRST CCIN Serial data line, input and output. Chipcard reset 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 destruc-

tion of the SIM. The CCIN signal is by default low and will change to high level if a SIM card is inserted. The CCIN signal is mandatory for applications that allow the user to remove the SIM card during operation. The CCIN signal 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 ELS81-US. Note [1]: No guarantee can be given, nor any liability accepted, if loss of data is encountered after removing the SIM card during operation. Also, no guarantee can be given for properly initializing any SIM card that the user inserts after having removed the SIM card during operation. In this case, the application must restart ELS81-US. Note [2]: On the evaluation board, the CCIN signal is inverted, thus the CCIN signal is by default high and will change to a low level if a SIM card is inserted. els81-us_hid_v01.004 Confidential / Preliminary 2017-09-27 Cinterion ELS81-US Hardware Interface Description 2.1 Application Interface 53 Page 31 of 107 The figure below shows a circuit to connect an external SIM card holder.

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 a GND line to shield the CCIO line from the CCCLK line. An example for an optimized ESD protection for the SIM interface is shown in Section 2.1.6.1. els81-us_hid_v01.004 Confidential / Preliminary 2017-09-27 Cinterion ELS81-US Hardware Interface Description 2.1 Application Interface 53 Page 32 of 107 2.1.6.1 Enhanced ESD Protection for SIM Interface To optimize ESD protection for the SIM interface it is possible to add ESD diodes to the SIM interface lines as shown in the example given in Figure 11.1 The example was designed to meet ESD protection according ETSI EN 301 489-1/7: Contact discharge: 4kV, air discharge: 8kV.

An alarm function is provided that allows to wake up ELS81-US without logging on to the RF network. In addition, you can use the VDDLP pad to backup the RTC from an external capacitor. The capacitor is charged from the internal LDO of ELS81-US. If the voltage supply at BATT+ is dis-

connected the RTC can be powered by the capacitor. The size of the capacitor determines the duration of buffering when no voltage is applied to ELS81-US, i.e. the greater the capacitor the longer ELS81-US will save the date and time. The RTC can also be supplied from an external battery (rechargeable or non-chargeable). In this case the electrical specification of the VDDLP pad (see Section 2.1.2) has to be taken in to account. Figure 12 shows an RTC backup configuration. A serial 1k resistor has to be placed on the application next to VDDLP. It limits the input current of an empty capacitor or battery. Module BATT+

The GPIO lines are shared with other interfaces or functions: Fast shutdown (see Section 2.1.13.4), status LED (see Section 2.1.13.1), the PWM functionality (see Section 2.1.11), an pulse counter (see Section 2.1.12), ASC0 (see Section 2.1.4), ASC1 (see Section 2.1.5), an SPI interface (see Section 2.1.10). The following table shows the configuration variants for the GPIO pads. All variants are mutu-

ally exclusive, i.e. a pad configured for instance as Status LED is locked for alternative usage.

It con-

sists of two lines, the serial data line I2CDAT and the serial clock line I2CCLK. The module acts as a single master device, e.g. the clock I2CCLK is driven by the module. I2CDAT is a bi-direc-

tional line. Each device connected to the bus is software addressable by a unique 7-bit ad-

dress, 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 bus use the AT^SSPI command. Detailed information on the AT^SSPI command as well explanations on the protocol and syntax required for data transmis-

sion can be found in [1]. The I2C interface can be powered via the V180 line of ELS81-US. If connected to the V180 line, the I2C interface will properly shut down when the module enters the Power Down mode. In the application I2CDAT and I2CCLK lines need to be connected to a positive supply voltage via a pull-up resistor.

The SPI is a synchronous serial interface for control and data transfer between ELS81-US and the external application. Only one application can be connected to the SPI and the interface supports only master mode. The transmission rates are up to 6.5Mbit/s. The SPI interface com-

prises the two data lines MOSI and MISO, the clock line SPI_CLK a well as the chip select line SPI_CS. The four GPIO lines can be configured as SPI interface signals as follows: GPIO3 --> SPI_CLK, GPIO16 --> MOSI, GPIO17 --> MISO and GPIO19 --> SPI_CS. The configuration is done by AT command (see [1]). It is non-volatile and becomes active after a module restart. The GPIO lines are also shared with the ASC1 signal lines and the ASC0 modem status signal line DSR0. To configure and activate the SPI interface use the AT^SSPI command. Detailed information on the AT^SSPI command as well explanations on the SPI modes required for data transmis-

sion can be found in [1]. In general, SPI supports four operation modes. The modes are different in clock phase and clock polarity. The modules SPI mode can be configured by using the AT command AT^SSPI. Make sure the module and the connected slave device works with the same SPI mode. Figure 16 shows the characteristics of the four SPI modes. The SPI modes 0 and 3 are the most common used modes. For electrical characteristics please refer to Table 2.

The PWM interface lines can be used, for example, to connect buzz-

ers. The PWM1 line is shared with GPIO7 and the PWM2 line is shared with GPIO6 (for GPIOs see Section 2.1.8). GPIO and PWM functionality are mutually exclusive. The startup behavior of the lines is shown in Figure 13. 2.1.12 Pulse Counter The GPIO8 line can be configured as pulse counter line COUNTER. The pulse counter inter-

face can be used, for example, as a clock (for GPIOs see Section 2.1.8). 2.1.13 Control Signals 2.1.13.1 Status LED The GPIO5 interface line can be configured to drive a status LED that indicates different oper-

ating modes of the module (for GPIOs see Section 2.1.8). GPIO and LED functionality are mu-

tually exclusive. To take advantage of this function connect an LED to the GPIO5/LED line as shown in Figure 17. VCC LED R3 GPIO5/

ceed +0.3V (see also Section 2.1.2.1). Exceeding this limit for any length of time might cause permanent damage to the module. It is therefore recommended to implement a power indication signal that reports the modules power state and shows whether it is active or in Power Down mode. While the module is in Power Down mode all signals with a high level from an external application need to be set to low state or high impedance state. The sample power indication circuit illustrated in Figure 18 denotes the modules active state with a low signal and the modules Power Down mode with a high signal or high impedance state. k 0 1 External power supply Power indication 22k 4.7k V180 VCORE k 0 0 1 k 0 0 1 Figure 18: Power indication circuit 2.1.13.3 Host Wakeup If no call, data or message transfer is in progress, the host may shut down its own USB inter-

face to save power. If a call or other request (URCs, messages) arrives, the host can be noti-

fied of these events and be woken up again by a state transition of the ASC0 interfaces RING0 line. This functionality should only be used with legacy USB applications not supporting the rec-

ommended USB suspend and resume mechanism as described in [5] (see also Section 2.1.3.1). For more information on how to configure the RING0 line by AT^SCFG command see [1].

The con-

figured FST_SHDN line is an active low control signal and must be applied for at least 1 milli-

seconds. If unused this line can be left open because of a configured internal pull-up resistor. Before setting the FST_SHDN line to low, the ON signal should be set to low (see Figure 19). Otherwise there might be back powering at the ON line in Power Down mode. The fast shutdown feature can be triggered using the AT command AT^SMSO=<fso>. For de-

tails see [1]. If triggered, a low impulse >1 milliseconds on the FST_SHDN line starts the fast shutdown. The fast shutdown procedure still finishes any data activities on the module's flash file system, thus ensuring data integrity, but will no longer deregister gracefully from the network, thus saving the time required for network deregistration.

VDDLP GPIO4/FST_SHDN ON VCORE V180 EMERG_RST Figure 19: Fast shutdown timing Please note that the normal software controlled shutdown using AT^SMSO will allow option for a fast shutdown by parameter <fso>, i.e., without network deregistration. However, in this case no URCs including shutdown URCs will be provided by the AT^SMSO command. Please also note that the fast shutdown operation does not allow the module deregister from the network, therefore, this practice is not recommended, and should not be conducted on reg-

ular basis. If it is used for energy saving reason, for instance, used in battery-driven solutions that require prompt system shutdown before battery depletion, discretion is advised in such case. els81-us_hid_v01.004 Confidential / Preliminary 2017-09-27 Cinterion ELS81-US Hardware Interface Description 2.2 RF Antenna Interface 53 2.2 RF Antenna Interface Page 42 of 107 The ELS81-US UMTS/LTE antenna interface comprises a UMTS/LTE main antenna as well as a UMTS/LTE Rx diversity antenna to improve signal reliability and quality1. The RF interface has an impedance of 50. ELS81-US is capable of sustaining a total mismatch at the antenna line without any damage, even when transmitting at maximum RF power. The external antenna must be matched properly to achieve best performance regarding radi-

ated power, modulation accuracy and harmonic suppression. Antenna matching networks are not included on the ELS81-US module and should be placed in the host application if the an-

tenna does not have an impedance of 50. Regarding the return loss ELS81-US provides the following values in the active band:

To prevent mismatch, special attention should be paid to these pads on the applications PCB. The wiring of the antenna connection, starting from the antenna pad to the applications anten-

na should result in a 50 line impedance. Line width and distance to the GND plane needs to be optimized with regard to the PCBs layer stack. Some examples are given in Section 2.2.3. To prevent receiver desensitization due to interferences generated by fast transients like high speed clocks on the external application PCB, it is recommended to realize the antenna con-

nection line using embedded Stripline rather than Micro-Stripline technology. Please see Sec-

tion 2.2.3.1 for examples of how to design the antenna connection in order to achieve the required 50 line impedance. For type approval purposes, the use of a 50 coaxial antenna connector (U.FL-R-SMT) might be necessary. In this case the U.FL-R-SMT connector should be placed as close as possible to ELS81-USs antenna pad. els81-us_hid_v01.004 Confidential / Preliminary 2017-09-27 Cinterion ELS81-US Hardware Interface Description 2.2 RF Antenna Interface 53 2.2.3 RF Line Routing Design Page 45 of 107 2.2.3.1 Line Arrangement Examples Several dedicated tools are available to calculate line arrangements for specific applications and PCB materials - for example from http://www.polarinstruments.com/ (commercial software) or from http://web.awrcorp.com/Usa/Products/Optional-Products/TX-Line/ (free software).

Usage of the various host interfaces depends on the desired features of the application. Because of the very low power consumption design, current flowing from any other source into the module circuit must be avoided, for example reverse current from high state external control lines. Therefore, the controlling application must be designed to prevent reverse current flow. Otherwise there is the risk of undefined states of the module during startup and shutdown or even of damaging the module. Because of the high RF field density inside the module, it cannot be guaranteed that no self interference might occur, depending on frequency and the applications grounding concept. The potential interferers may be minimized by placing small capacitors (47pF) at suspected lines

(e.g. RXD0, VDDLP, and ON). While developing SMT applications it is strongly recommended to provide test points for certain signals, i.e., lines to and from the module - for debug and/or test purposes. The SMT application should allow for an easy access to these signals. For details on how to implement test points see [3]. 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 po-

sition of components. Depending on the micro controller used by an external application ELS81-USs digital input and output lines may require level conversion. Section 2.3.1 shows a possible sample level conver-

sion circuit. Note: ELS81-US is not intended for use with cables longer than 3m. Disclaimer No warranty, either stated or implied, is provided on the sample schematic diagram shown in Figure 27 and the information detailed in this section. As functionality and compliance with na-

tional regulations depend to a great amount on the used electronic components and the indi-

vidual application layout manufacturers are required to ensure adequate design and operating safeguards for their products using ELS81-US modules. els81-us_hid_v01.004 Confidential / Preliminary 2017-09-27 Cinterion ELS81-US Hardware Interface Description 2.3 Sample Application 53 Page 52 of 107 For switch on circuit see Section 3.2.1 VDDLP 100k RESET PWR_IND ON EMERG_RST VDDLP V180 VCORE Main antenna Diversity antenna GND ANT_MAIN GND GND ANT_DRX GND 150F, Low ESR!

ELS81-US immediately switches off after having started and detected these inappropriate conditions. In extreme cases this can cause permanent dam-

age to the module. 3.2.1 Turn on ELS81-US ELS81-US can be turned on as described in the following sections:

Connecting the operating voltage BATT+ (see Section 3.2.1.1). Hardware driven switch on by ON line: Starts Normal mode (see Section 3.2.1.2). After startup or restart, the module will send the URC ^SYSSTART that notifies the host appli-

cation that the first AT command can be sent to the module (see also [1]). 3.2.1.1 Connecting ELS81-US BATT+ Lines Figure 29 shows sample external application circuits that allow to connect (and also to tempo-

rarily disconnect) the modules BATT+ lines from the external applications power supply. Figure 29 illustrates the application of power employing an externally controlled microcontrol-

ler. The voltage supervisory circuit ensures that the power is disconnected and applied again depending on given thresholds. The transistor T2 mentioned in Figure 29 should have an RDS_ON value < 50m in order to min-

imize voltage drops. Such circuits could be useful to maximize power savings for battery driven applications or to completely switch off and restart the module after a firmware update. After connecting the BATT+ lines the module can then be (re-)started as described in Section 3.2.1.2 and Section 3.2.2. els81-us_hid_v01.004 Confidential / Preliminary 2017-09-27 Cinterion ELS81-US Hardware Interface Description 3.2 Power Up/Power Down Scenarios 77 Page 56 of 107 VBATT_IN

The ON signal is an edge triggered signal and allows the input voltage level up to 5V. The mod-

ule starts into normal mode on detecting the rising edge of the ON signal. The rising edge of ON signal must be applied at least 100 milliseconds later than BATT+. See Figure 31. The following Figure 30 shows recommendations for possible switch-on circuits. VDDLP Option 1 Option 2 R1 1k

RTC backup R2 ON Figure 30: ON circuit options It is recommended to set a serial 1kOhm resistor between the ON circuit and the external ca-

pacitor or battery at the VDDLP power supply (i.e., RTC backup circuit). This serial resistor pro-

tection is necessary in case the capacitor or battery has low power (is empty).With Option 2 the typical resistor values are: R1 = 150k and R2 = 3k. But the resistor values depend on the cur-

rent gain from the employed PNP resistor. Please note that the ON signal is an edge triggered signal. This implies that a micro-second high pulse on the signal line suffices to almost immediately switch on the module, as shown in Figure 31. After module startup the ON signal should always be set to low to prevent possible back powering at this pad.1 1. Please take due discretion when designing the filtering circuit, especially ESD, which may cause unin-

tended switch on. els81-us_hid_v01.004 Confidential / Preliminary 2017-09-27 Cinterion ELS81-US Hardware Interface Description 3.2 Power Up/Power Down Scenarios 77 Page 58 of 107

Caution: Use the EMERG_RST line only when, due to serious problems, the software is not responding for more than 5 seconds. Pulling the EMERG_RST line causes the loss of all infor-

mation stored in the volatile memory. Therefore, this procedure is intended only for use in case of emergency, e.g. if ELS81-US does not respond, if reset or shutdown via AT command fails. els81-us_hid_v01.004 Confidential / Preliminary 2017-09-27 Cinterion ELS81-US Hardware Interface Description 3.2 Power Up/Power Down Scenarios 77 Page 61 of 107 Signal States after Startup 3.2.3 Table 10 lists the states each interface signal passes through during reset phase and the first firmware initialization. For further firmware startup initializations the values may differ because of different GPIO line configurations. The reset state is reached with the rising edge of the EMERG_RST signal - either after a normal module startup (see Section 3.2.1.2) or after a reset (see Section 3.2.2.2). After the reset state has been reached the firmware initialization state begins. The firmware initialization is complet-

ed as soon as the ASC0 interface lines CTS0, DSR0 and RING0 as well as the ASC1 interface line CTS1 have turned low (see Section 2.1.4 and Section 2.1.5). Now, the module is ready to receive and transmit data.

Software controlled shutdown procedure: Software controlled by sending an AT command over the serial application interface. See Section 3.2.4.1. Hardware controlled shutdown procedure: Hardware controlled by disconnecting the mod-

ules power supply lines BATT+ (see Section 3.2.1.1). Automatic shutdown (software controlled): See Section 3.2.5

- Takes effect if ELS81-US board temperature or voltage levels exceed a critical limit. Switch off ELS81-US Using AT Command 3.2.4.1 The best and safest approach to powering down ELS81-US is to issue the appropriate AT com-

mand. This procedure lets ELS81-US 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. After sending the switch off command AT^SMSO, be sure not to enter any further AT commands until the module was re-

started. CAUTION: Be sure not to disconnect the operating voltage VBATT+ before V180 pad has gone low. Otherwise you run the risk of losing data, or in some rare cases even to render the module inoperable. To monitor the V180 line, it is recommended to implement a power indication circuit as de-

scribed in Section 2.1.13.2. While ELS81-US is in Power Down mode the application interface is switched off and must not be fed from any other voltage source. Therefore, your application must be designed to avoid any current flow into any digital pads of the application interface. els81-us_hid_v01.004 Confidential / Preliminary 2017-09-27 Cinterion ELS81-US Hardware Interface Description 3.2 Power Up/Power Down Scenarios 77 Page 63 of 107 AT^SMSO System power down procedure Power down BATT+

ELS81-US board is exceeding the critical limits of overtemperature or undertemperature

(see Section 3.2.5.1) Undervoltage or overvoltage is detected (see Section 3.2.5.2 and Section 3.2.5.3) The automatic shutdown procedure is equivalent to the power-down initiated with an AT com-

mand, i.e. ELS81-US logs off from the network and the software enters a secure state avoiding loss of data. Thermal Shutdown 3.2.5.1 The board temperature is constantly monitored by an internal NTC resistor located on the PCB. The values detected by the NTC resistor are measured directly on the board and therefore, are not fully identical with the ambient temperature. Each time the board temperature goes out of range or back to normal, ELS81-US instantly dis-

plays 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 (for details see [1]):

AT^SCTM=1: Presentation of URCs is always enabled. AT^SCTM=0 (default): Presentation of URCs is enabled during the 2 minute guard period after start-up of ELS81-US. After expiry of the 2 minute guard period, the presentation of URCs will be disabled, i.e. no URCs with alert levels "1" or ''-1" will be generated. URCs indicating the level "2" or "-2" are instantly followed by an orderly shutdown. The pre-

sentation 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 Section 3.5. Refer to Table 11 for the associ-

ated URCs. Table 11: Temperature dependent behavior Sending temperature alert (2min after ELS81-US start-up, otherwise only if URC presentation enabled)

When the average supply voltage measured by ELS81-US approaches the undervolt-

age shutdown threshold (i.e., 0.05V offset) the module will send the following URC:

^SBC: Undervoltage Warning The undervoltage warning is sent only once - until the next time the module is close to the un-

dervoltage shutdown threshold. If the voltage continues to drop below the specified undervoltage shutdown threshold, the mod-

ule will send the following URC:

^SBC: Undervoltage Shutdown This alert is sent only once before the module shuts down cleanly without sending any further messages. This type of URC does not need to be activated by the user. It will be output automatically when fault conditions occur. Note: For battery powered applications it is strongly recommended to implement a BATT+ con-

necting circuit as described in Section 3.2.1.1 in order to not only be able save power, but also to restart the module after an undervoltage shutdown where the battery is deeply discharged. Also note that the undervoltage threshold is calculated for max. 400mV voltage drops during transmit burst. Power supply sources for external applications should be designed to tolerate 400mV voltage drops without crossing the lower limit of 3.0 V. For external applications oper-

ating at the limit of the allowed tolerance the default undervoltage threshold may be adapted by subtracting an offset. For details see [1]: AT^SCFG= "MEShutdown/sVsup/threshold". Overvoltage Shutdown 3.2.5.3 The overvoltage shutdown threshold is the specified maximum supply voltage VBATT+ given in Table 2. When the average supply voltage measured by ELS81-US approaches the overvolt-

age shutdown threshold (i.e., 0.05V offset) the module will send the following URC:

^SBC: Overvoltage Warning The overvoltage warning is sent only once - until the next time the module is close to the over-

voltage shutdown threshold. If the voltage continues to rise above the specified overvoltage shutdown threshold, the module will send the following URC:

^SBC: Overvoltage Shutdown This alert is sent only once before the module shuts down cleanly without sending any further messages. 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 ELS81-US components are directly linked to BATT+ and, therefore, the supply voltage remains applied at major parts of ELS81-US. Especially the power amplifier linked to BATT+RF is very sensitive to high voltage and might even be destroyed. els81-us_hid_v01.004 Confidential / Preliminary 2017-09-27 Cinterion ELS81-US Hardware Interface Description 3.3 Power Saving 77 Power Saving 3.3 ELS81-US can be configured to control power consumption:

Page 66 of 107 Using the AT command AT^SPOW it is possible to specify a so-called power saving mode for the module (<mode> = 2; for details on the command see [1]). The modules UART inter-

faces (ASC0 and ASC1) are then deactivated and will only periodically be activated to be able to listen to network paging messages as described in Section 3.3.1 and Section 3.3.2. See Section 3.3.3 for a description on how to immediately wake up ELS81-US again using RTS0. Please note that the AT^SPOW setting has no effect on the USB interface. As long as the USB connection is active, the module will not change into its SLEEP state to reduce its func-

tionality to a minimum and thus minimizing its current consumption. To enable switching into SLEEP mode, the USB connection must therefore either not be present at all or the USB host must bring its USB interface into Suspend state. Also, VUSB_IN should always be kept enabled for this functionality. See Universal Serial Bus Specification Revision 2.01 for a description of the Suspend state. Power Saving while Attached to WCDMA Networks 3.3.1 The power saving possibilities while attached to a WCDMA network depend on the paging tim-

ing cycle of the base station. During normal WCDMA operation, i.e., the module is connected to a WCDMA network, the duration of a power saving period varies. It may be calculated using the following formula:

t = 2DRX value * 10 ms (WCDMA frame duration). DRX (Discontinuous Reception) in WCDMA networks is a value between 6 and 9, thus result-

ing in power saving intervals between 0.64 and 5.12 seconds. The DRX value of the base sta-

tion is assigned by the WCDMA network operator. In the pauses between listening to paging messages, the module resumes power saving, as shown in Figure 36. Figure 36: Power saving and paging in WCDMA networks The varying pauses explain the different potential for power saving. The longer the pause the less power is consumed. 1. The specification is ready for download on http://www.usb.org/developers/docs/

els81-us_hid_v01.004 Confidential / Preliminary 2017-09-27 Cinterion ELS81-US Hardware Interface Description 3.3 Power Saving 77 Page 67 of 107 Generally, power saving depends on the modules application scenario and may differ from the above mentioned normal operation. The power saving interval may be shorter than 0.64 sec-

onds or longer than 5.12 seconds. Power Saving while Attached to LTE Networks 3.3.2 The power saving possibilities while attached to an LTE network depend on the paging timing cycle of the base station. During normal LTE operation, i.e., the module is connected to an LTE network, the duration of a power saving period varies. It may be calculated using the following formula:

t = DRX Cycle Value * 10 ms DRX cycle value in LTE networks is any of the four values: 32, 64, 128 and 256, thus resulting in power saving intervals between 0.32 and 2.56 seconds. The DRX cycle value of the base station is assigned by the LTE network operator. In the pauses between listening to paging messages, the module resumes power saving, as shown in Figure 37. Figure 37: Power saving and paging in LTE networks The varying pauses explain the different potential for power saving. The longer the pause the less power is consumed. Generally, power saving depends on the modules application scenario and may differ from the above mentioned normal operation. The power saving interval may be shorter than 0.32 sec-

onds or longer than 2.56 seconds. els81-us_hid_v01.004 Confidential / Preliminary 2017-09-27 Cinterion ELS81-US Hardware Interface Description 3.3 Power Saving 77 Page 68 of 107 3.3.3 Wake-up via RTS0 RTS0 can be used to wake up ELS81-US from SLEEP mode configured with AT^SPOW. Assertion of RTS0 (i.e., toggle from inactive high to active low) serves as wake up event, thus allowing an external application to almost immediately terminate power saving. After RTS0 assertion, the CTS0 line signals module wake up, i.e., readiness of the AT command interface. It is therefore recommended to enable RTS/CTS flow control (default setting). Figure 38 shows the described RTS0 wake up mechanism.

There are two separate voltage domains for BATT+:

BATT+BB with a line mainly for the baseband power supply. BATT+RF with a line for the UMTS/LTE power amplifier supply. Please note that throughout the document BATT+ refers to both voltage domains and power supply lines - BATT+BB and BATT+RF. The power supply of ELS81-US has to be a single voltage source at BATT+BB and BATT+RF. 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 baseband using low drop linear voltage regulators and a DC-DC step down switching regulator. Switches the module's power voltages for the power-up and -down procedures. SIM switch to provide SIM power supply.

The module continuously measures the voltage at intervals depending on the operating mode of the RF interface. The duration of measuring ranges from 0.5 seconds in TALK/DATA mode to 50 seconds when ELS81-US is in IDLE mode or Limited Service (deregistered). The dis-

played voltage (in mV) is averaged over the last measuring period before the AT^SBV com-

mand was executed. If the measured voltage drops below or rises above the voltage shutdown thresholds, the mod-

ule will send an "^SBC" URC and shut down (for details see Section 3.2.5). els81-us_hid_v01.004 Confidential / Preliminary 2017-09-27 Cinterion ELS81-US Hardware Interface Description 3.5 Operating Temperatures 77 Page 73 of 107 Operating Temperatures 3.5 Please note that the modules lifetime, i.e., the MTTF (mean time to failure) may be reduced, if operated outside the extended temperature range.

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 ELS81-US module. An example for an enhanced ESD protection for the SIM interface is given in Section 2.1.6.1. ELS81-US has been tested according to group standard ETSI EN 301 489-1 (see Table 22) and test standard EN 61000-4-2. Electrostatic values can be gathered from the following table.

Section 2.3). However, all other signal lines have no EMI measures on the module and there are no blocking measures at the modules interface to an external application. Dependent on the specific application design, it might be useful to implement further EMI mea-

sures on some signal lines at the interface between module and application. These measures are described below. There are five possible variants of EMI measures (A-E) that may be implemented between module and external application depending on the signal line (see Figure 41 and Table 16). Pay attention not to exceed the maximum input voltages and prevent voltage overshots if using in-

ductive EMC measures. The maximum value of the serial resistor should be lower than 1k on the signal line. The max-

imum value of the capacitor should be lower than 50pF on the signal line. Please observe the electrical specification of the modules SMT application interface and the external applications interface.

For more information on issues related to SMT module integration see also [3]. Note: To avoid short circuits between signal tracks on an external application's PCB and vari-

ous markings at the bottom side of the module, it is recommended not to route the signal tracks on the top layer of an external PCB directly under the module, or at least to ensure that signal track routes are sufficiently covered with solder resist. 4.2.1 SMT PCB Assembly Land Pattern and Stencil 4.2.1.1 The land pattern and stencil design as shown below is based on Gemalto characterizations for lead-free solder paste on a four-layer test PCB and a respectively 110 m and 150 m thick stencil. The land pattern given in Figure 44 reflects the modules pad layout, including signal pads and ground pads (for pad assignment see Section 2.1.1). The stencil design illustrated in Figure 45 and Figure 46 is recommended by Gemalto M2M as a result of extensive tests with Gemalto M2M Daisy Chain modules.

cess. Characterization tests should attempt to optimize the SMT process with regard to board level reliability. This can be done by performing the following physical tests on sample boards: Peel test, bend test, tensile pull test, drop shock test and temperature cycling. Sample surface mount checks are described in [3]. It is recommended to characterize land patterns before an actual PCB production, taking indi-

vidual processes, materials, equipment, stencil design, and reflow profile into account. For land and stencil pattern design recommendations see also Section 4.2.1.1. Optimizing the solder stencil pattern design and print process is necessary to ensure print uniformity, to decrease sol-

der voids, and to increase board level reliability. Daisy chain modules for SMT characterization are available on request. For details refer to [3]. Generally, solder paste manufacturer recommendations for screen printing process parame-

ters and reflow profile conditions should be followed. Maximum ratings are described in Section 4.2.3. Moisture Sensitivity Level 4.2.2 ELS81-US comprises components that are susceptible to damage induced by absorbed mois-

ture. Gemalto M2Ms ELS81-US module complies with the latest revision of the IPC/JEDEC J-STD-

020 Standard for moisture sensitive surface mount devices and is classified as MSL 4. For additional moisture sensitivity level (MSL) related information see Section 4.2.4 and Sec-

Module 1 3 2 4 Temperature sensors (1-4) 4.2.3.2 Maximum Temperature and Duration The following limits are recommended for the SMT board-level soldering process to attach the module:

A maximum module temperature of 245C. This specifies the temperature as measured at the modules top side. A maximum duration of 30 seconds at this temperature. Please note that while the solder paste manufacturers' recommendations for best temperature and duration for solder reflow should generally be followed, the limits listed above must not be exceeded. ELS81-US is specified for one soldering cycle only. Once ELS81-US is removed from the ap-

plication, the module will very likely be destroyed and cannot be soldered onto another appli-

cation. els81-us_hid_v01.004 Confidential / Preliminary 2017-09-27 Cinterion ELS81-US Hardware Interface Description 4.2 Mounting ELS81-US onto the Application Platform 92 4.2.4 Durability and Mechanical Handling Page 85 of 107 Storage Conditions 4.2.4.1 ELS81-US modules, as delivered in tape and reel carriers, must be stored in sealed, moisture barrier anti-static bags.

rier bag (MBB) it was stored in. As specified in the IPC/JEDEC J-STD-033 Standard, the manufacturing site processing the modules should have ambient temperatures below 30C and a relative humidity below 60%. Baking 4.2.4.3 Baking conditions are specified on the moisture sensitivity label attached to each MBB (see Figure 52 for details):

It is not necessary to bake ELS81-US, if the conditions specified in Section 4.2.4.1 and Sec-

tion 4.2.4.2 were not exceeded. It is necessary to bake ELS81-US, if any condition specified in Section 4.2.4.1 and Section 4.2.4.2 was exceeded. If baking is necessary, the modules must be put into trays that can be baked to at least 125C. Devices should not be baked in tape and reel carriers at any temperature. Electrostatic Discharge 4.2.4.4 Electrostatic discharge (ESD) may lead to irreversable damage for the module. It is therefore advisable to develop measures and methods to counter ESD and to use these to control the electrostatic environment at manufacturing sites. Please refer to Section 3.6 for further information on electrostatic discharge. els81-us_hid_v01.004 Confidential / Preliminary 2017-09-27 Cinterion ELS81-US Hardware Interface Description 4.3 Packaging 92 Page 87 of 107 4.3 Packaging Tape and Reel 4.3.1 The single-feed tape carrier for ELS81-US is illustrated in Figure 48.

Manufacturers of the cellular terminal are advised to convey the following safety information to users and oper-

ating 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. Gemalto M2M assumes no liability for customers failure to comply with these precautions. 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 guide-

lines posted in sensitive areas. Medical equipment may be sensitive to RF energy. The operation of cardiac pacemakers, other implanted medical equipment and hear-

ing 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 manufac-

turer 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 can-

not be switched on inadvertently. The operation of wireless appliances in an aircraft is forbidden to prevent 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 elec-

trical 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 driv-

ing 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 opera-

tion can constitute a safety hazard. 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 com-

munications, 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 termi-

nal or mobile. els81-us_hid_v01.004 Confidential / Preliminary 2017-09-27 Cinterion ELS81-US Hardware Interface Description 7 Appendix 106 Page 105 of 107 7 Appendix List of Parts and Accessories 7.1 Table 26: List of parts and accessories Description ELS81-US Supplier Gemalto M2M Standard module Ordering information Gemalto M2M IMEI:
