If the voltage drops below 3.3V, the module will turn off automatically. The following figure shows the voltage drop during transmitting burst in 2G network, the voltage drop will be less in 3G network. UC20_Hardware_Design Confidential / Released 30 / 84 UMTS/HSPA Module Series UC20 User Manual Figure 6: Voltage Drop during Transmitting Burst To decrease voltage drop, 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. The main power supply from an external application has to be a single voltage source and expanded to two sub paths with star structure. 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. Three ceramic capacitors (100nF, 33pF, 10pF) are recommended to be applied to the VBAT pins. The capacitors should be placed close to the UC20s VBAT pins. 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. The following figure shows star structure of the power supply. Figure 7: Star Structure of the Power Supply 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.

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 about 3.8V and the maximum load current is 3A. Figure 8: Reference Circuit of Power Supply 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]. 3.7. Turn on and off Scenarios 3.7.1. Turn on Module Using the PWRKEY The following table shows the pin definition of PWRKEY.

Normal power down procedure: Turn off the module using the PWRKEY pin. Normal power down procedure: Turn off the module using 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 Using the PWRKEY Pin Driving the PWRKEY to a low level voltage 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.

After logging off, module sends out POWERED DOWN and shut down the internal power supply. The power on VBAT pins is not allowed to turn off before the URC POWERED DOWN is output to avoid data loss. If logging off is not done within 60s, module will shut down internal power supply forcibly. After that moment, the module enters the power down mode, no other AT commands can be executed and only the RTC is still active. 3.7.2.2. Turn off Module Using AT Command It is also a safe way to use AT command AT+QPOWD to turn off the module, which is similar to 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.

Keep layout of USIM card as close as possible to the module. Assure 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 connector 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 connector. 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. 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 connector. The pull-up resistor on USIM_DATA line can improve anti-jamming capability when long layout trace and sensitive occasion is applied, and should be placed close to the USIM connector.

UC20_Hardware_Design Confidential / Released 53 / 84 UMTS/HSPA Module Series UC20 User Manual 4 GNSS Receiver 4.1. General Description UC20 includes a fully integrated global navigation satellite system solution that supports the latest generation gpsOne Gen8 of Qualcomm (GPS and GLONASS). Compared with GPS only, dual systems increase usable constellation, reduce coverage gaps and TTFF, and increase positioning accuracy, especially in rough urban environments. UC20 works in standalone mode, allows device to demodulate GNSS assistance data, calculate position without any assistance from the network, suitable for various application needing lowest-cost, accurate position determination. UC20 supports Qualcomm gpsOneXTRA technology (one kind of A-GNSS), which will download XTRA file from the internet server to enhance the TTFF. XTRA file contains predicted GPS and GLONASS satellites coordinates and clock biases valid for up to 7days. It is the best if XTRA file is downloaded once every 1-2 days. And UC20 also supports SBAS (including WAAS, EGNOS and MSAS), which will improve fix accuracy. UC20 provides power-saving solution named DPO (Dynamic Power Optimization), which attempts to turn off GNSS RF parts, reduces current consumption by 50% at most without impact on TTFF, thus extends battery life, and maximizes talk and standby time as well. UC20 supports standard NMEA-0183 protocol, and outputs NMEA sentences with 1Hz via USB interface by default. By default, UC20 GNSS engine is switched off, it has to be switched on with AT command.

Storage UC20 is stored in the vacuum-sealed bag. The restriction of storage condition is shown as below. Shelf life in sealed bag is 12 months at < 40C/90%RH. After this bag is opened, devices that will be subjected to reflow solder or other high temperature process must be:
Mounted within 72 hours at factory conditions of 30C/60%RH. Stored at < 10% RH. Devices require bake before mounting, if:
Humidity indicator card is > 10% when read 23C5C. Mounted for more than 72 hours at factory conditions of 30C/60% RH. If baking is required, devices may be baked for 48 hours at 125C5C. NOTE As plastic container cannot be subjected to high temperature, module needs to be taken out from container to high temperature (125C) bake. If shorter bake times are desired, please refer to IPC/JEDECJ-STD-033 for bake procedure. 8.2. Manufacturing and Welding The squeegee should push the paste on the surface of the stencil that makes the paste fill the stencil openings and penetrate to the PCB. The force on the squeegee should be adjusted so as to produce a clean stencil surface on a single pass. To ensure the module soldering quality, the thickness of stencil at the hole of the module pads should be 0.18mm. For details, please refer to document [6]. UC20_Hardware_Design Confidential / Released 75 / 84 UMTS/HSPA Module Series UC20 User Manual It is suggested that peak reflow temperature is 235 ~ 245C (for SnAg3.0Cu0.5 alloy). Absolute max reflow temperature is 260C. To avoid damage to the module when it was repeatedly heated, it is suggested that the module should be mounted after the first panel has been reflowed. The following picture is the actual diagram which we have operated. Figure 45: Liquids Temperature 8.3. Packaging UC20 is packaged in the tap and reel carriers.
