Full attention must be given to driving at all times in order to reduce the risk of an

accident. Using a mobile while driving (even with a handsfree kit) cause distraction

and can lead to an accident. You must comply with laws and regulations restricting

the use of wireless devices while driving.

Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it

switched off. The operation of wireless appliances in an aircraft is forbidden to

prevent interference with communication systems. Consult the airline staff about

the use of wireless devices on boarding the aircraft, if your device offers a Airplane

Mode which must be enabled prior to boarding an aircraft.

Switch off your wireless device when in hospitals or clinics or other health care facilities. These requests are desinged to prevent possible interference with sentitive medical equipment.

UMTS cellular terminals or mobiles operate over radio frequency signal and

cellular network and cannot be guaranteed to connect in all conditions, for example

no mobile fee or an invalid SIM card. While you are in this condition and need

emergent help, please remember using emergency call. In order to make or

receive call, the cellular terminal or mobile must be switched on and in a service

area with adequate cellular signal strength.

Your cellular terminal or mobile contains a transmitter and receiver. When it is ON ,

it receives and transmits radio frequency energy. RF interference can occur if it is

used close to TV set, radio, computer or other electric equipment.

In locations with potencially explosive atmospheres, obey all posted signs to turn

off wireless devices such as your phone or other cellular terminals. Areas with

potencially exposive atmospheres including fuelling areas, below decks on boats,

fuel or chemical transfer or storage facilities, areas where the air contains

chemicals or particles such as grain, dust or metal powders.

3.6. Power Supply

3.6.1. Power Supply Pins

UG95 provides four VBAT pins dedicated 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 Pins

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 100µF 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 UG95’s

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.

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 isn’t 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.

The power-down scenario is illustrated as the following figure.

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.

Please refer to document [1] for details about the AT command of AT+QPOWD.

3.9. 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 1KΩ 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)  VRTC  I - The current consumption of the RTC circuitry when VBAT = 0.(Ampere)  B  C - The backup capacitance. (Farad)

UG95 Hardware Design

In order to enhance the reliability and availability of the USIM card in customer’s 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 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

(http://www.willsemi.com) ESDA6V8AV6. The 22Ω 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 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.

UG95 provides one Pulse Code Modulation (PCM) digital interface for audio design, which supports the

following features:

 Supports 8, 16, 32 bit mode with short frame synchronization, the PCM support 8 bit mode by default

since the PCM codec default configuration is AT+QDAI=1. Refer to document [1] for more details.

 Supports master mode.  Supports audio sample rate 8 kHz.

The following table shows the pin definition of PCM and I2C interface which can be applied on audio

codec design.

Table 16: Pin Definition of PCM and I2C Interface

In PCM audio format the MSB of the channel included in the frame (PCM_SYNC) is clocked on the

second CLK falling edge after the PCM_SYNC pulse rising edge. The period of the PCM_SYNC signal

(frame) lasts for Data word bit +1 clock pulses.

UG95’s firmware has integrated the configuration on ALC5616 application with I2C interface. You can

execute command AT+QDAI=3 to configure the ALC5616 codec, and refer to document [1] for more

UMTS/HSPA Module Series

As plastic container cannot be subjected to high temperature, module needs to be taken out from

container to high temperature (125ºC) bake. If shorter bake times are desired, please refer to

IPC/JEDECJ-STD-033 for bake procedure.

7 Storage and Manufacturing

7.1. Storage

UG95 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 < 40ºC/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 ≤ 30ºC/60%RH.  Stored at <10% RH.

Devices require bake, before mounting, if:

 Humidity indicator card is >10% when read 23ºC±5ºC.  Mounted for more than 72 hours at factory conditions of ≤ 30ºC/60% RH.

If baking is required, devices may be baked for 48 hours at 125ºC±5ºC.

7.2. 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 0.13mm. For details, please refer to document [6].

It is suggested that peak reflow temperature is 235 ~ 245ºC (for SnAg3.0Cu0.5 alloy). Absolute max

reflow temperature is 260ºC. 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.

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.
