Sleep Mode UG95 is able to reduce its current consumption to a minimum value during the sleep mode. The following section describes power saving procedure of UG95. 3.5.1.1. UART Application If application processor communicates with module via UART interface, the following preconditions can UG95_Hardware_Design Confidential / Released 21 / 67 UMTS/HSPA Module Series UG95 Hardware Design 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. 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.

3.6.2. Decrease Voltage Drop The power supply range of the module is 3.4V~ 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 UG95s VBAT pins. The following figure shows star structure of the power supply. The main power supply from an external application has to 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 whose reverse zener voltage is 5.1V and dissipation power is more than 0.5W. UG95_Hardware_Design Confidential / Released 24 / 67 UMTS/HSPA Module Series UG95 Hardware Design Figure 5: 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 3.4V. If the voltage drops below 3.4V, 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 isnt 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.

It is recommended to use an open drain/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. The STATUS pin output a high level, after UG95 is turned on. A simple reference circuit is illustrated in the following figure. Figure 7: Turn on the Module Using Driving Circuit The other way to control the PWRKEY is using a button directly. A TVS component is indispensable to be placed nearby the button for ESD protection.

Turn off Module The following procedures can be used to turn off the module:
Normal power down procedure: Turn off the module using the PWRDWN_N 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.

Figure 12: Timing of Turning off Module During power-down procedure, module will log off network and save important data. After logging off, module sends out OK, and then 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. The power down mode can also be indicated by the STATUS pin. 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 PWRDWN_N Pin.

RTC Interface The RTC (Real Time Clock) can be powered by an external capacitor through the pin VRTC when the module is powered down and there is no power supply for the VBAT. If the voltage supply at VBAT is disconnected, the RTC can be powered by the capacitor. The capacitance determines the duration of buffering when no voltage is applied to UG95. The capacitor is charged from the internal LDO of UG95 when there is power supply for the VBAT. A serial 1K resistor had been placed on the application inside the module. It limits the input current of the capacitor. The following figure shows the reference circuit for VRTC backup. Figure 16: RTC Supply from Capacitor In order to evaluate the capacitance of capacitor according to the backup time, we have to consider the following parameters:
VRTC - The starting voltage of the capacitor. ( Volt) VRTCMIN - The minimum voltage acceptable for the RTC circuit.( Volt) B Time - Backup Time.(Second) C - The backup capacitance. (Farad) I - The current consumption of the RTC circuitry when VBAT = 0.(Ampere) UG95_Hardware_Design Confidential / Released 33 / 67 Large Capacitance CapacitorModuleRTC Core1KVRTCC UMTS/HSPA Module Series UG95 Hardware Design When the power is off and only VRTC is running, the way of calculating the backup capacitor as follows:
C= B Time *I/( VRTC-VRTCMIN) For example, when the capacitor is 1000uF:
VRTC = 1.8V VRTCMIN = 1.0V I = 2uA C = 1000uF The backup time is about 400s. 3.10. UART Interface The module provides 7 lines UART interface. UART interface supports 4800, 9600, 19200, 38400, 57600, 115200, 230400, 460800 and 921600bps baud rate, and the default is auto-baud rate. This interface can be used for data transmission, AT communication or firmware upgrade.

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 holder 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 holder. 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

UG95_Hardware_Design Confidential / Released 41 / 67 UMTS/HSPA Module Series UG95 Hardware Design The following figure shows the reference circuit of USB interface. Figure 24: 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. 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. Keep the ESD components as closer to the USB connector as possible. It is suggested to reserve RC circuit near USB connector for debug. The USB interface is recommended to be reserved for firmware upgrade in your design. The following figure shows the recommended test points.
