2General Descriptions
2.1. Product Description
M95 R2.0 is a quad-band GSM/GPRS module supporting GSM850/EGSM900/DCS1800/PCS1900.
UG96 is an UMTS/HSPA module. UG95 is also an UMTS/HSPA module that includes two variants,
UG95-A and UG95-E. UG96, UG95 and M95 R2.0 are designed as compatible products, and customers
can choose a suitable product according to application requirements. The compatible design guideline
ensures a smooth migration from M95 R2.0 to UG96/UG95 modules.

1. 1) Within operation temperature range, the module is 3GPP compliant.
2. 2) Within extended temperature range, the module remains the ability to establish and maintain a
voice, SMS, data transmission, emergency call, etc. There is no unrecoverable malfunction. There
are also no effects on radio spectrum and no harm to radio network. Only one or more parameters like
Pout might reduce in their value and exceed the specified tolerances. When the temperature returns to
normal operating temperature levels, the module will meet 3GPP specifications again.

Figure 2: Combined Pin Assignment of UG96&UG95&M95 R2.0
1. The blue pins of UG96&UG95 are the additional pins compared with M95 R2.0.
2. The pin names marked in red in the inside area are M95 R2.0’s.
3. The black pins of UG96, UG95 and M95 R2.0 are compatible pins in main functions.
4. Due to the different functions of pin 24/25 of UG96&UG95 and the green pins of M95 R2.0, different
resistors need to be mounted when using UG96, UG95 or M95 R2.0 for compatible design. For
details, please refer to document [4].
5. The purple pins are different pins in the main functions.

2. The pins marked in red are compatible pins, but their functions are different.
3. The black pins are compatible pins in main functions.
4. Keep all reserved and unused pins unconnected.
5. All GND pins should be connected to ground.

6. The AGND pin of M95 R2.0 should be routed as single-ended to main ground when analog audio is
used in single-ended application. Otherwise, it can be connected to GND directly.
7. “*” means under development.
8. 1) DTR pin can be used as SIM1_PRESENCE pin via AT command. For more details, please refer to
document [3].
9. 2) When (U)SIM2 interface is used, DCD pin can be used as SIM2_RST pin. For more details, please
refer to document [5].

4Hardware Reference Design
The following chapters describe compatible design among UG96, UG95 and M95 R2.0 on main functions.
4.1. Power Supply
4.1.1. Power Supply Reference Design
Power design for a module is critical to its performance. The power supply of UG96, UG95 and M95 R2.0
should be able to provide sufficient current up to 2.0A. If the voltage drop between the input and output is
not too high, it is suggested that an LDO should be used to supply power for the 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 the power supply.
The following figure shows a reference design for +5V input power source. The typical output of the power
supply is about 3.8V and the maximum load current is 3.0A.
