The module has registered to the GSM network and is ready to send and receive data. GSM connection is ongoing. In this mode, the power consumption is decided by the configuration of power control level (PCL), dynamic DTX control and the working RF band. The module is ready for GPRS data transfer, but no data transfer is going on. In this case, power consumption depends on network setting and GPRS configuration. There is GPRS data in transfer (PPP, TCP or UDP). In this mode, power consumption is decided by the PCL, working RF band and GPRS multi-slot configuration. The module is ready for data transfer in EDGE mode, but no data is currently sent or received. In this case, power consumption depends on network settings and EDGE configuration. There is EDGE data in transfer (PPP, TCP or UDP). In this mode, power consumption is decided by the PCL, working RF band and EDGE multi-slot configuration.

The module has registered to the HSDPA network and the module is ready to send and receive data. HSDPA data transfer is ongoing. In this mode, the power consumption is decided by network setting (e.g. TPC pattern) and data transfer rate. Minimum Functionality Mode Sleep Mode Power Down Mode AT+CFUN=0 command can set the module entering into a minimum functionality mode without removing the power supply. In this case, both RF function and USIM card will be invalid. In this mode, the current consumption of the module will be reduced to the minimal level. During this mode, the module can still receive paging message, SMS, voice call and TCP/UDP data from the network normally. Any URC can be output even the module in Sleep Mode. In this mode, the power management unit shuts down the power supply for the baseband part and RF part. Software is not active. The serial interface is not accessible. Operating voltage (connected to VBAT_RF and VBAT_BB) remains applied. 3.5. Power Saving 3.5.1. Sleep Mode UC15 is able to reduce its current consumption to a minimum value during the sleep mode. The following section describes power saving procedure of UC15. 3.5.1.1. UART Application If application processor communicates with module via UART interface, the following preconditions can let the module enter into the sleep mode. Execute AT command AT+QSCLK=1 to enable the sleep mode. Drive DTR to high level. The following figure shows the connection between the module and application processor. UC15_Hardware_Design Confidential / Released 25 / 79 UMTS/HSDPA Module Series UC15 Hardware Design Figure 3: UART Sleep Application The RI of module is used to wake up the processor, and AP_READY will detect the sleep state of processor (can be configured to high level or low level detection). You should pay attention to the level match shown in dotted line between module and processor. Drive DTR to low level will wake up the module. 3.5.1.2. USB Application with Suspend Function If application processor communicates with module via USB interface, and processor supports USB suspend function, following preconditions can let the module enter into the sleep mode. Execute AT command AT+QSCLK=1 to enable the sleep mode. The processors USB bus which is connected with the module USB interface enters into suspended state. The following figure shows the connection between the module and processor. Figure 4: USB Application with Suspend Function UC15_Hardware_Design Confidential / Released 26 / 79 UMTS/HSDPA Module Series UC15 Hardware Design When the processors USB bus returns to resume state, the module will be woken up. 3.5.1.3. USB Application without Suspend Function If application processor communicates with module via USB interface, and processor does not support USB suspend function, you should disconnect USB_VBUS with additional control circuit to let the module enter into sleep mode. Execute AT command AT+QSCLK=1 to enable the sleep mode. Disconnect USB_VBUS. The following figure shows the connection between the module and application processor. Figure 5: USB Sleep Application without Suspend Function Supply power to USB_VBUS will wake up the module. In sleep mode, the module can still receive paging message, SMS, voice call and TCP/UDP data from the network normally, but the UART port is not accessible. 3.5.2. Minimum Functionality Mode Minimum functionality mode reduces the functionality of the module to minimum level, thus minimizes the current consumption at the same time. This mode can be set as below:
Command AT+CFUN provides the choice of the functionality levels: <fun>=0, 1, 4. AT+CFUN=0: Minimum functionality, RF part and USIM card will be closed. AT+CFUN=1: Full functionality (by default). UC15_Hardware_Design Confidential / Released 27 / 79 UMTS/HSDPA Module Series UC15 Hardware Design AT+CFUN=4: Disable RF function (airplane mode). All AT commands related to RF function are not accessible. For detailed information about command AT+CFUN, please refer to document [1]. 3.6. Power Supply 3.6.1. Power Supply Pins UC15 provides four VBAT pins to connect with the external power supply. There are two separate voltage domains for VBAT. VBAT_RF with two pads for module RF. VBAT_BB with two pads for module baseband. The following table shows the VBAT pins and ground pins. Table 6: VBAT and GND Pin Pin Name Pin No. Description Min. Typ. Max.

The power supply range of the module is 3.3~4.3V. Because of the voltage drop during the transmitting time, a bypass capacitor of about 100F with low ESR should be used. Multi-layer ceramic chip (MLCC) capacitor can provide the best combination of low ESR. Three ceramic capacitors (100nF, 33pF, 10pF) are recommended to be applied to the VBAT pins. The capacitors should be placed close to the VBAT pins of UC15. The following figure shows star structure of the power supply. The main power supply from an external application should be a single voltage source and has to be expanded to two sub paths with star structure. In addition, in order to get a stable power source, it is suggested to use a zener diode of which reverse zener voltage is 5.1V and dissipation power is more than 0.5W. UC15_Hardware_Design Confidential / Released 28 / 79 UMTS/HSDPA Module Series UC15 Hardware Design Figure 6: Star Structure of the Power Supply Please pay special attention to the power supply design for applications. Make sure the input voltage will never drop below 3.3V. If the voltage drops below 3.3V, the module will turn off automatically. The PCB traces from the VBAT pins to the power source must be wide enough to ensure that there is not too much voltage drop occurs in the transmitting procedure. The width of VBAT_BB trace should be no less than 1mm, and the width of VBAT_RF trace should be no less than 2mm, and the principle of the VBAT trace is the longer, the wider. 3.6.3. Reference Design for Power Supply The power design for the module is very important, since the performance of power supply for the module largely depends on the power source. The power supply is capable of providing the sufficient current up to 2A at least. If the voltage drop between the input and output is not too high, it is suggested to use a LDO to supply power for module. If there is a big voltage difference between the input source and the desired output (VBAT), a buck converter is preferred to be used as a power supply. The following figure shows a reference design for +5V input power source. The designed output for the power supply is 3.88V and the maximum load current is 3A. Figure 7: Reference Circuit of Power Supply UC15_Hardware_Design Confidential / Released 29 / 79 UMTS/HSDPA Module Series UC15 Hardware Design 3.6.4. Monitor the Power Supply You can use the AT+CBC command to monitor the VBAT_BB voltage value. For more details, please refer to document [1]. 3.6.5. VDD_EXT UC15 has a LDO power output, named VDD_EXT. The VDD_EXT is available and output voltage is 2.6V by default, rated at 100mA. The following table shows electrical characteristics of VDD_EXT.

VIHmax=2.1V VIHmin=1.3V VILmax=0.5V Pull-up to 1.8V internally with 200k resistor. UC15_Hardware_Design Confidential / Released 30 / 79 UMTS/HSDPA Module Series UC15 Hardware Design When UC15 is in power down mode, it can be turned on to normal mode by driving the PWRKEY pin to low level at least 0.1s. It is recommended to use an open collector driver to control the PWRKEY. You can monitor the level of the STATUS pin to judge whether the module is turned on or not. After STATUS pin outputting a high level, module is turned on. A simple reference circuit is illustrated in the following figure. Figure 8: Turn on the Module by Driving Circuit The other way to control the PWRKEY is to use a button directly. A TVS component is indispensable to be placed nearby the button for ESD protection. When pressing the key, electrostatic strike may generate from finger. A reference circuit is shown in the following figure. Figure 9: Turn on the Module by Keystroke UC15_Hardware_Design Confidential / Released 31 / 79 UMTS/HSDPA Module Series UC15 Hardware Design The turn on scenarios is illustrated as the following figure. Figure 10: Timing of Turning on Module NOTE Make sure that VBAT is stable before pulling down PWRKEY pin. The time between them is recommended to be more than 0.03s. 3.7.2. Turn off Module The following procedures can be used to turn off the module:
Normal power down procedure: Turn off the module by PWRKEY pin. Normal power down procedure: Turn off the module by command AT+QPOWD. Automatic shutdown: Turn off the module automatically if under-voltage or over-voltage is detected. 3.7.2.1. Turn off Module by PWRKEY Pin Drive the PWRKEY to low level at least 0.6s, the module will execute power-down procedure after PWRKEY is released. The power-down scenario is illustrated as the following figure. UC15_Hardware_Design Confidential / Released 32 / 79 UMTS/HSDPA Module Series UC15 Hardware Design Figure 11: Timing of Turning off Module During power-down procedure, module will send out URC NORMAL POWER DOWN via URC port first, then log off network and save important data. After logging off, module sends out POWERED DOWN and shuts down the internal power supply. The power on VBAT pins are not allowed to be switched off before the URC POWERED DOWN is output to avoid data loss. If module is not logged off within 60s, module will force to shut down internal power supply. After that moment, the module enters into power down mode, no other AT commands can be executed. The power down mode can also be indicated by the STATUS pin. 3.7.2.2. Turn off Module by AT Command It is also a safe way to use AT command AT+QPOWD to turn off the module, which is similar to the way of turning off the module via PWRKEY Pin. Please refer to document [1] for details about the AT command of AT+QPOWD. 3.7.2.3. Automatic Shutdown The module will constantly monitor the voltage applied on the VBAT_BB, if the voltage 3.5V, the following URC will be presented:
+QIND: vbatt,-1 If the voltage 4.21V, the following URC will be presented:
+QIND: vbatt,1 The uncritical voltage is 3.3V to 4.3V, If the voltage > 4.35V or < 3.2V, the module would automatically shut down itself. UC15_Hardware_Design Confidential / Released 33 / 79 UMTS/HSDPA Module Series UC15 Hardware Design If the voltage < 3.2V, the following URC will be presented:
+QIND: vbatt,-2 If the voltage > 4.35V, the following URC will be presented:
+QIND: vbatt,2 NOTE The value of voltage threshold can be revised by AT command AT+QCFG=vbatt, refer to document

Figure 13: Timing of Resetting Module NOTE The low-level pulse through the RESET_N pin cannot last for more than 0.2s, otherwise the module will be powered off. 3.9. UART Interface The module provides one 7-wire UART interface, and is designed as the DCE (Data Communication Equipment), following the traditional DCE-DTE (Data Terminal Equipment) connection. UART interface supports 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400, 460800 and 921600bps baud rate. The default is 115200bps, while autobauding is not supported.

Figure 18: 5V Level Match Circuit UC15_Hardware_Design Confidential / Released 38 / 79 UMTS/HSDPA Module Series UC15 Hardware Design The following figure is an example of connection between module and PC. A RS232 level shifter IC or circuit must be inserted between module and PC, since UART interface do not support the RS232 level, while support the CMOS level only. Figure 19: RS232 Level Shift Circuit NOTES 1. Rising edge on DTR will let the module exit from the data mode by default. It can be disabled by command. Refer to document [1] about AT&D and AT&V for details. 2. DCD is used as data mode indication. Please refer to document [1] about command AT&C and AT&V for details. 3.10. Behavior of the RI You can use command AT+QCFG=risignaltype, physical to configure RI behavior:
No matter which port URC is presented on, URC will trigger the behavior on RI pin. UC15_Hardware_Design Confidential / Released 39 / 79 UMTS/HSDPA Module Series UC15 Hardware Design NOTE URC can be output from UART port, USB AT port and USB modem port by command AT+QURCCFG. The default port is USB AT port. In additional, RI behavior can be configured flexible. The default behavior of the RI is shown as below.

An electret microphone is usually recommended. AIN1 and AIN2 are both differential input channels. AOUT1 and AOUT2 may be used for both receiver and speaker outputs. AOUT1 channel is typically used for a receiver, while AOUT2 channel is typically used for headset or speaker. AOUT1 channel is a differential channel and AOUT2 is a single-ended channel. SPK2P and AGND can establish a pseudo differential mode. Both AOUT1 and AOUT2 support voice and ringtone output, and so on. These two audio channels can be swapped by AT+QAUDPATH command. For more details, please refer to document [1]. Use command AT+QAUDPATH to select audio channel:
0: AIN1/AOUT1 (normal audio channel), the default value is 0. 1: AIN2/AOUT2 (auxiliary audio channel). 2: PCM channel. For each channel, you can use AT+QMIC to adjust the input gain level of microphone. You can also use AT+CLVL to adjust the output gain level of receiver and speaker. AT+QSIDET is to set the side-tone gain level. For more details, please refer to document [1]. 3.11.1. Decrease TDD Noise and Other Noise The 33pF capacitor is applied for filtering out 900MHz RF interference when the module is transmitting at GSM900/EGSM900MHz. TDD noise could be heard without this capacitor. Moreover, the 10pF capacitor here is for filtering out 1800/1900MHz RF interference. However, the self-resonant frequency point of a capacitor largely depends on the material and production technique. Therefore, customer should depend on its capacitor vendor to choose the most suitable capacitor for filtering out GSM850MHz and PCS1900MHz separately. UC15_Hardware_Design Confidential / Released 41 / 79 UMTS/HSDPA Module Series UC15 Hardware Design The severity degree of the RF interference in the voice channel during GSM transmitting period largely depends on the application design. In some cases, GSM850 TDD noise is more severe; while in other cases, PCS1900 TDD noise is more obvious. Therefore, customer can have a choice based on test results. Sometimes, even no RF filtering capacitor is required. The capacitor which is used for filtering out RF noise should be close to audio interface. Audio alignment should be as short as possible. In order to decrease radio or other signal interference, the position of RF antenna should be kept away from audio interface and audio alignment. Power alignment and audio alignment should not be parallel, and power alignment should be far away from audio alignment. The differential audio traces should be placed according to the differential signal layout rules. 3.11.2.

PCM and I2C Interface UC15 provides one Pulse Code Modulation (PCM) digital interface for audio design with 16-bit linear data formats, which supports the following modes:
Primary mode (short sync, works as both master and slave) Auxiliary mode (long sync, works as master only) UC15 supports an 8 kHz short sync mode at 2048 kHz, the data is sampled on the falling edge of the PCM_CLK and transmitted on the rising edge, and the PCM_SYNC falling edge represents the MSB. UC15 also supports an 8 kHz long sync mode at 128 kHz, the data is sampled on the falling edge of the PCM_CLK and transmitted on the rising edge, and the PCM_SYNC rising edge represents the MSB. The following figures show the different timing relationships of these modes. Figure 27: Primary Mode Timing UC15_Hardware_Design Confidential / Released 46 / 79 UMTS/HSDPA Module Series UC15 Hardware Design Figure 28: Auxiliary Mode Timing The following table shows the pin definition of PCM and I2C interface which can be applied on audio codec design.

The reference circuit for using a 6-pin USIM card holder is illustrated as the following figure. UC15_Hardware_Design Confidential / Released 49 / 79 UMTS/HSDPA Module Series UC15 Hardware Design Figure 31: Reference Circuit of the 6-Pin USIM Card In order to enhance the reliability and availability of the USIM card in customers application, please follow the following criterion in the USIM circuit design:
Keep layout of USIM card as close as possible to the module. Assure the possibility of the length of the trace is less than 200mm. Keep USIM card signal away from RF and VBAT alignment. Assure the ground between module and USIM cassette short and wide. Keep the width of ground and USIM_VDD no less than 0.5mm to maintain the same electric potential. The decouple capacitor of USIM_VDD should be less than 1uF and must be near to USIM cassette. To avoid cross-talk between USIM_DATA and USIM_CLK, keep them away with each other and shield them with surrounded ground. In order to offer good ESD protection, it is recommended to add TVS such as WILL
(http://www.willsemi.com) ESDA6V8AV6. The capacitance of ESD component is less than 50pF. The 22 resistors should be added in series between the module and the USIM card so as to suppress the EMI spurious transmission and enhance the ESD protection. The 33pF capacitors are used for filtering interference of EGSM900. Please note that the USIM peripheral circuit should be close to the USIM card holder. The pull-up resistor on USIM_DATA line can improve anti-jamming capability when long layout trace and sensitive occasion is applied. 3.13.2.

Figure 34: Reference Circuit of USB Application In order to ensure the USB interface design corresponding with the USB 2.0 specification, please comply with the following principles. It is important to route the USB signal traces as differential pairs with total grounding. The impedance of USB differential trace is 90ohm. UC15_Hardware_Design Confidential / Released 53 / 79 UMTS/HSDPA Module Series UC15 Hardware Design Keep the ESD components as closer to the USB connector as possible. Pay attention to the influence of junction capacitance of ESD component on USB data lines. Typically, the capacitance value should be less than 2pF such as ESD9L5.0ST5G. Do not route signal traces under crystals, oscillators, magnetic devices and RF signal traces. It is important to route the USB differential traces in inner-layer with ground shielding not only upper and lower layer but also right and left side. NOTE UC15 module can only be used as a slave device. The USB interface is recommended to be reserved for firmware upgrade in your design. The following figure shows the recommended test points.

Table 5: Overview of Operating Modes Mode Normal Operation Details GSM Idle GSM Talk/Data GPRS Idle GPRS Data EDGE Idle EDGE Data Software is active. The module has registered to the GSM network and is ready to send and receive data. GSM connection is ongoing. In this mode, the power consumption is decided by the configuration of power control level (PCL), dynamic DTX control and the working RF band. The module is ready for GPRS data transfer, but no data transfer is going on. In this case, power consumption depends on network setting and GPRS configuration. There is GPRS data in transfer (PPP, TCP or UDP). In this mode, power consumption is decided by the PCL, working RF band and GPRS multi-slot configuration. The module is ready for data transfer in EDGE mode, but no data is currently sent or received. In this case, power consumption depends on network settings and EDGE configuration. There is EDGE data in transfer (PPP, TCP or UDP). In this mode, power consumption is decided by the PCL, working RF band and EDGE multi-slot configuration.

The module has registered to the HSDPA network and the module is ready to send and receive data. HSDPA data transfer is ongoing. In this mode, the power consumption is decided by network setting (e.g. TPC pattern) and data transfer rate. Minimum Functionality Mode Sleep Mode Power Down Mode AT+CFUN=0 command can set the module entering into a minimum functionality mode without removing the power supply. In this case, both RF function and USIM card will be invalid. In this mode, the current consumption of the module will be reduced to the minimal level. During this mode, the module can still receive paging message, SMS, voice call and TCP/UDP data from the network normally. Any URC can be output even the module in Sleep Mode. In this mode, the power management unit shuts down the power supply for the baseband part and RF part. Software is not active. The serial interface is not accessible. Operating voltage (connected to VBAT_RF and VBAT_BB) remains applied. 3.5. Power Saving 3.5.1. Sleep Mode UC15 is able to reduce its current consumption to a minimum value during the sleep mode. The following section describes power saving procedure of UC15. 3.5.1.1. UART Application If application processor communicates with module via UART interface, the following preconditions can let the module enter into the sleep mode. Execute AT command AT+QSCLK=1 to enable the sleep mode. Drive DTR to high level. The following figure shows the connection between the module and application processor. UC15_Hardware_Design Confidential / Released 25 / 78 UMTS/HSDPA Module Series UC15 Hardware Design Figure 3: UART Sleep Application The RI of module is used to wake up the processor, and AP_READY will detect the sleep state of processor (can be configured to high level or low level detection). You should pay attention to the level match shown in dotted line between module and processor. Drive DTR to low level will wake up the module. 3.5.1.2. USB Application with Suspend Function If application processor communicates with module via USB interface, and processor supports USB suspend function, following preconditions can let the module enter into the sleep mode. Execute AT command AT+QSCLK=1 to enable the sleep mode. The processors USB bus which is connected with the module USB interface enters into suspended state. The following figure shows the connection between the module and processor. Figure 4: USB Application with Suspend Function UC15_Hardware_Design Confidential / Released 26 / 78 UMTS/HSDPA Module Series UC15 Hardware Design When the processors USB bus returns to resume state, the module will be woken up. 3.5.1.3. USB Application without Suspend Function If application processor communicates with module via USB interface, and processor does not support USB suspend function, you should disconnect USB_VBUS with additional control circuit to let the module enter into sleep mode. Execute AT command AT+QSCLK=1 to enable the sleep mode. Disconnect USB_VBUS. The following figure shows the connection between the module and application processor. Figure 5: USB Sleep Application without Suspend Function Supply power to USB_VBUS will wake up the module. In sleep mode, the module can still receive paging message, SMS, voice call and TCP/UDP data from the network normally, but the UART port is not accessible. 3.5.2. Minimum Functionality Mode Minimum functionality mode reduces the functionality of the module to minimum level, thus minimizes the current consumption at the same time. This mode can be set as below:
Command AT+CFUN provides the choice of the functionality levels: <fun>=0, 1, 4. AT+CFUN=0: Minimum functionality, RF part and USIM card will be closed. AT+CFUN=1: Full functionality (by default). UC15_Hardware_Design Confidential / Released 27 / 78 UMTS/HSDPA Module Series UC15 Hardware Design AT+CFUN=4: Disable RF function (airplane mode). All AT commands related to RF function are not accessible. For detailed information about command AT+CFUN, please refer to document [1]. 3.6. Power Supply 3.6.1. Power Supply Pins UC15 provides four VBAT pins to connect with the external power supply. There are two separate voltage domains for VBAT. VBAT_RF with two pads for module RF. VBAT_BB with two pads for module baseband. The following table shows the VBAT pins and ground pins. Table 6: VBAT and GND Pin Pin Name Pin No. Description Min. Typ. Max.

The power supply range of the module is 3.3~4.3V. Because of the voltage drop during the transmitting time, a bypass capacitor of about 100F with low ESR should be used. Multi-layer ceramic chip (MLCC) capacitor can provide the best combination of low ESR. Three ceramic capacitors (100nF, 33pF, 10pF) are recommended to be applied to the VBAT pins. The capacitors should be placed close to the VBAT pins of UC15. The following figure shows star structure of the power supply. The main power supply from an external application should be a single voltage source and has to be expanded to two sub paths with star structure. In addition, in order to get a stable power source, it is suggested to use a zener diode of which reverse zener voltage is 5.1V and dissipation power is more than 0.5W. UC15_Hardware_Design Confidential / Released 28 / 78 UMTS/HSDPA Module Series UC15 Hardware Design Figure 6: Star Structure of the Power Supply Please pay special attention to the power supply design for applications. Make sure the input voltage will never drop below 3.3V. If the voltage drops below 3.3V, the module will turn off automatically. The PCB traces from the VBAT pins to the power source must be wide enough to ensure that there is not too much voltage drop occurs in the transmitting procedure. The width of VBAT_BB trace should be no less than 1mm, and the width of VBAT_RF trace should be no less than 2mm, and the principle of the VBAT trace is the longer, the wider. 3.6.3. Reference Design for Power Supply The power design for the module is very important, since the performance of power supply for the module largely depends on the power source. The power supply is capable of providing the sufficient current up to 2A at least. If the voltage drop between the input and output is not too high, it is suggested to use a LDO to supply power for module. If there is a big voltage difference between the input source and the desired output (VBAT), a buck converter is preferred to be used as a power supply. The following figure shows a reference design for +5V input power source. The designed output for the power supply is 3.88V and the maximum load current is 3A. Figure 7: Reference Circuit of Power Supply UC15_Hardware_Design Confidential / Released 29 / 78 UMTS/HSDPA Module Series UC15 Hardware Design 3.6.4. Monitor the Power Supply You can use the AT+CBC command to monitor the VBAT_BB voltage value. For more details, please refer to document [1]. 3.6.5. VDD_EXT UC15 has a LDO power output, named VDD_EXT. The VDD_EXT is available and output voltage is 2.6V by default, rated at 100mA. The following table shows electrical characteristics of VDD_EXT.

VIHmax=2.1V VIHmin=1.6V VILmax=0.5V Pull-up to 1.8V internally with 200k resistor. UC15_Hardware_Design Confidential / Released 30 / 78 UMTS/HSDPA Module Series UC15 Hardware Design When UC15 is in power down mode, it can be turned on to normal mode by driving the PWRKEY pin to low level at least 0.1s. It is recommended to use an open collector driver to control the PWRKEY. You can monitor the level of the STATUS pin to judge whether the module is turned on or not. After STATUS pin outputting a high level, module is turned on. A simple reference circuit is illustrated in the following figure. Figure 8: Turn on the Module by Driving Circuit The other way to control the PWRKEY is to use a button directly. A TVS component is indispensable to be placed nearby the button for ESD protection. When pressing the key, electrostatic strike may generate from finger. A reference circuit is shown in the following figure. Figure 9: Turn on the Module by Keystroke UC15_Hardware_Design Confidential / Released 31 / 78 UMTS/HSDPA Module Series UC15 Hardware Design The turn on scenarios is illustrated as the following figure. Figure 10: Timing of Turning on Module NOTE Make sure that VBAT is stable before pulling down PWRKEY pin. The time between them is recommended to be more than 0.03s. 3.7.2. Turn off Module The following procedures can be used to turn off the module:
Normal power down procedure: Turn off the module by PWRKEY pin. Normal power down procedure: Turn off the module by command AT+QPOWD. Automatic shutdown: Turn off the module automatically if under-voltage or over-voltage is detected. 3.7.2.1. Turn off Module by PWRKEY Pin Drive the PWRKEY to low level at least 0.6s, the module will execute power-down procedure after PWRKEY is released. The power-down scenario is illustrated as the following figure. UC15_Hardware_Design Confidential / Released 32 / 78 UMTS/HSDPA Module Series UC15 Hardware Design Figure 11: Timing of Turning off Module During power-down procedure, module will send out URC NORMAL POWER DOWN via URC port first, then log off network and save important data. After logging off, module sends out POWERED DOWN and shuts down the internal power supply. The power on VBAT pins are not allowed to be switched off before the URC POWERED DOWN is output to avoid data loss. If module is not logged off within 60s, module will force to shut down internal power supply. After that moment, the module enters into power down mode, no other AT commands can be executed. The power down mode can also be indicated by the STATUS pin. 3.7.2.2. Turn off Module by AT Command It is also a safe way to use AT command AT+QPOWD to turn off the module, which is similar to the way of turning off the module via PWRKEY Pin. Please refer to document [1] for details about the AT command of AT+QPOWD. 3.7.2.3. Automatic Shutdown The module will constantly monitor the voltage applied on the VBAT_BB, if the voltage 3.5V, the following URC will be presented:
+QIND: vbatt,-1 If the voltage 4.21V, the following URC will be presented:
+QIND: vbatt,1 The uncritical voltage is 3.3V to 4.3V, If the voltage > 4.35V or < 3.2V, the module would automatically shut down itself. UC15_Hardware_Design Confidential / Released 33 / 78 UMTS/HSDPA Module Series UC15 Hardware Design If the voltage < 3.2V, the following URC will be presented:
+QIND: vbatt,-2 If the voltage > 4.35V, the following URC will be presented:
+QIND: vbatt,2 NOTE The value of voltage threshold can be revised by AT command AT+QCFG=vbatt, refer to document

Figure 13: Timing of Resetting Module NOTE The low-level pulse through the RESET_N pin cannot last for more than 0.2s, otherwise the module will be powered off. 3.9. UART Interface The module provides one 7-wire UART interface, and is designed as the DCE (Data Communication Equipment), following the traditional DCE-DTE (Data Terminal Equipment) connection. UART interface supports 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400, 460800 and 921600bps baud rate. The default is 115200bps, while autobauding is not supported.

A RS232 level shifter IC or circuit must be inserted between module and PC, since UART interface do not support the RS232 level, while support the CMOS level only. Figure 19: RS232 Level Shift Circuit NOTES 1. Rising edge on DTR will let the module exit from the data mode by default. It can be disabled by command. Refer to document [1] about AT&D and AT&V for details. 2. DCD is used as data mode indication. Please refer to document [1] about command AT&C and AT&V for details. 3.10.

An electret microphone is usually recommended. AIN1 and AIN2 are both differential input channels. AOUT1 and AOUT2 may be used for both receiver and speaker outputs. AOUT1 channel is typically used for a receiver, while AOUT2 channel is typically used for headset or speaker. AOUT1 channel is a differential channel and AOUT2 is a single-ended channel. SPK2P and AGND can establish a pseudo differential mode. Both AOUT1 and AOUT2 support voice and ringtone output, and so on. These two audio channels can be swapped by AT+QAUDPATH command. For more details, please refer to document [1]. Use command AT+QAUDPATH to select audio channel:
0: AIN1/AOUT1 (normal audio channel), the default value is 0. 1: AIN2/AOUT2 (auxiliary audio channel). 2: PCM channel. For each channel, you can use AT+QMIC to adjust the input gain level of microphone. You can also use AT+CLVL to adjust the output gain level of receiver and speaker. AT+QSIDET is to set the side-tone gain level. For more details, please refer to document [1]. 3.11.1. Decrease TDD Noise and Other Noise The 33pF capacitor is applied for filtering out 900MHz RF interference when the module is transmitting at GSM900/EGSM900MHz. TDD noise could be heard without this capacitor. Moreover, the 10pF capacitor here is for filtering out 1800/1900MHz RF interference. However, the self-resonant frequency point of a capacitor largely depends on the material and production technique. Therefore, customer should depend on its capacitor vendor to choose the most suitable capacitor for filtering out GSM850MHz, EGSM900MHz, DCS1800MHz and PCS1900MHz separately. UC15_Hardware_Design Confidential / Released 41 / 78 UMTS/HSDPA Module Series UC15 Hardware Design The severity degree of the RF interference in the voice channel during GSM transmitting period largely depends on the application design. In some cases, GSM850/EGSM900 TDD noise is more severe; while in other cases, DCS1800/PCS1900 TDD noise is more obvious. Therefore, customer can have a choice based on test results. Sometimes, even no RF filtering capacitor is required. The capacitor which is used for filtering out RF noise should be close to audio interface. Audio alignment should be as short as possible. In order to decrease radio or other signal interference, the position of RF antenna should be kept away from audio interface and audio alignment. Power alignment and audio alignment should not be parallel, and power alignment should be far away from audio alignment. The differential audio traces should be placed according to the differential signal layout rules. 3.11.2.

PCM and I2C Interface UC15 provides one Pulse Code Modulation (PCM) digital interface for audio design with 16-bit linear data formats, which supports the following modes:
Primary mode (short sync, works as both master and slave) Auxiliary mode (long sync, works as master only) UC15 supports an 8 kHz short sync mode at 2048 kHz, the data is sampled on the falling edge of the PCM_CLK and transmitted on the rising edge, and the PCM_SYNC falling edge represents the MSB. UC15 also supports an 8 kHz long sync mode at 128 kHz, the data is sampled on the falling edge of the PCM_CLK and transmitted on the rising edge, and the PCM_SYNC rising edge represents the MSB. The following figures show the different timing relationships of these modes.

UC15_Hardware_Design Confidential / Released 49 / 78 UMTS/HSDPA Module Series UC15 Hardware Design Figure 31: Reference Circuit of the 6-Pin USIM Card In order to enhance the reliability and availability of the USIM card in customers application, please follow the following criterion in the USIM circuit design:
Keep layout of USIM card as close as possible to the module. Assure the possibility of the length of the trace is less than 200mm. Keep USIM card signal away from RF and VBAT alignment. Assure the ground between module and USIM cassette short and wide. Keep the width of ground and USIM_VDD no less than 0.5mm to maintain the same electric potential. The decouple capacitor of USIM_VDD should be less than 1uF and must be near to USIM cassette. To avoid cross-talk between USIM_DATA and USIM_CLK, keep them away with each other and shield them with surrounded ground. In order to offer good ESD protection, it is recommended to add TVS such as WILL
(http://www.willsemi.com) ESDA6V8AV6. The capacitance of ESD component is less than 50pF. The 22 resistors should be added in series between the module and the USIM card so as to suppress the EMI spurious transmission and enhance the ESD protection. The 33pF capacitors are used for filtering interference of EGSM900. Please note that the USIM peripheral circuit should be close to the USIM card holder. The pull-up resistor on USIM_DATA line can improve anti-jamming capability when long layout trace and sensitive occasion is applied. 3.13.2.

Figure 34: Reference Circuit of USB Application In order to ensure the USB interface design corresponding with the USB 2.0 specification, please comply with the following principles. It is important to route the USB signal traces as differential pairs with total grounding. The impedance of USB differential trace is 90ohm. UC15_Hardware_Design Confidential / Released 53 / 78 UMTS/HSDPA Module Series UC15 Hardware Design Keep the ESD components as closer to the USB connector as possible. Pay attention to the influence of junction capacitance of ESD component on USB data lines. Typically, the capacitance value should be less than 2pF such as ESD9L5.0ST5G. Do not route signal traces under crystals, oscillators, magnetic devices and RF signal traces. It is important to route the USB differential traces in inner-layer with ground shielding not only upper and lower layer but also right and left side. NOTE UC15 module can only be used as a slave device. The USB interface is recommended to be reserved for firmware upgrade in your design. The following figure shows the recommended test points.

21.4 UC15_Hardware_Design Confidential / Released 78 / 78 UMTS/HSDPA Module Series UC15 Hardware Design 10 Appendix C GPRS Multi-slot Class Twenty-nine classes of GPRS multi-slot modes are defined for MS in GPRS specification. Multi-slot classes are product dependant, and determine the maximum achievable data rates in both the uplink and downlink directions. Written as 3+1 or 2+2, the first number indicates the amount of downlink timeslots, while the second number indicates the amount of uplink timeslots. The active slots determine the total number of slots the GPRS device can use simultaneously for both uplink and downlink communications. The description of different multi-slot classes is shown in the following table.
