1.1. Safety Information
The following safety precautions must be observed during all phases of the operation, such as usage,
service or repair of any cellular terminal or mobile incorporating UG96 module. Manufacturers of the cellular
terminal should send the following safety information to users and operating personnel and to incorporate
these guidelines into all manuals supplied with the product. If not so, Quectel does not take on any liability
for customer failure to comply with these precautions.
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.
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.

3.6.2. Decrease Voltage Drop
The power supply range of the module is 3.3V~ 4.3V. 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 following figure shows the
voltage drop during transmitting burst in 2G network, the voltage drop will be less in 3G network.
< 400mV
Current
VBAT
≤ 2.0A
burst burst
Min. 3.3V
Figure 6: Voltage Drop during Transmitting Burst
To decrease voltage drop, 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. The main power supply
from an external application has to be a single voltage source and splits into 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 UG96’s VBAT pins. In addition, in order to get a stable power
source, it is suggested that you should 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.

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 that a LDO
should be used 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.

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 using command AT+QPOWD.
Emergency power down procedure: Turn off the module using the PWRDWN_N pin.
Automatic shutdown: Turn off the module automatically if under-voltage or over-voltage is detected.
3.7.2.1. Turn off Module Using AT Command
There are several different ways to turn off the module. It is recommended to turn off the module from AT
command AT+QPOWD. It is a safe way to turn off the module. This command will let the module log off
from the network and allow the firmware to save important data before completely disconnecting the
power supply.

Figure 12: Timing of Turning off through AT Command
During power-down procedure, module will log off from network and save important data. After logging off,
module sends out “OK”, and then sends out “POWERED DOWN” and shuts down the internal power
supply. The power on VBAT pins is not allowed to be turned off before the URC “POWERED DOWN” is
output to avoid data loss. If logging off is not done within 40s, 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,
only the RTC is still active. 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 UG96.
The capacitor is charged from the internal LDO of UG96 when there is power supply for the VBAT. A
serial 1KΩ resistor has 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 19: RTC Supply from Capacitor
In order to evaluate the capacitance of capacitor according to the backup time, you have to consider the
following parameters:
VRTC - The starting voltage of the capacitor. (Volt)
VRTCMIN - The minimum voltage acceptable for the RTC circuit.(Volt)
I - The current consumption of the RTC circuitry when VBAT = 0.(Ampere)
B Time - Backup Time.(Second)
C - The backup capacitance. (Farad)
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.

In order to enhance the reliability and availability of the USIM card in customer’s application, please follow
the criteria below in the USIM circuit design:
Keep layout of USIM card as close as possible to the module. Assure the length of the trace is as less
than 200mm as possible.
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). 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
33pF capacitors are used for filtering interference of EGSM900. Please note that the USIM peripheral
circuit should be close to the USIM holder.
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 holder.

Figure 25: 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.
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.

The module is not protected against electrostatics discharge (ESD) in general. 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 the module.

7 Storage and Manufacturing
7.1. Storage
UG96 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.
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.
7.2. 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].
NOTE

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.
