supports 1.8V and 3.0V).
②Recommend do not use the module’s pins which are defined as RESERVED or NC,
they need to be floated.
3.3 Power Interface
CLM920_TE5 module power interface consists of two parts:
VBAT for the module power supply;
UIM_PWR for SIM card operation power supply;

CLM920_TE5 module with single power supply mode, the module provides 5-way power
supply pin, with 14-pin GND. VBAT power supply range of 3.3-4.2V, the recommended
power supply is 3.7V / 2A . The module’s peak current will reach 2.5A when transmit data
or call under HSPA/UTMS/GSM, which resulting in a large ripple on the power. If instant
voltage drop makes the VBAT power too low or the current supply insufficient, the
module will power off or restart. To ensure that the module works properly, all power and
ground pins should be connected to use and able to provide enough power supply.
Figure 3- 3 GSM TDMA Power Supply Voltage Drop
On the premise of the VBAT can provide enough power, connect two 470uF/6.3V
tantalum capacitors in parallel near to the power, also connect another 10pF, 33pF,

Figure 3- 7 Reference Design of MOS to control the power switch
①In order to prevent the surge and over voltage damage the module, suggest that
connect a 5.1 V / 500mW zener diode on to the module’s VBAT pin in parallel.
②Suggest that use another three ceramic capacitors(33pF ,10pF,100nF)near to the
VBAT pin.
③The minimum working voltage of the module is 3.3V. Due to the peak current will
reach 2.5A while transmit data or call under GSM making a large ripple on the power,
the supply voltage can’t lower than 3.3V.
3.3.3 VDD_EXT 1V8 output
The pin 17th will output 1.8V after CLM920_TE5 module boots up successfully. Its
maximum current load is 50mA. Using this PIN you can determine whether the module
power-on correctly or not. The VDD_EXT can also be used as external power supply,
such as LED, etc.
