5. Electrical, reliability and radio characteristics
5.1. Absolute maximum ratings
Absolute maximum ratings for power supply and voltage on digital and analog pins of module are
listed in the following table:
Table 31: Absolute maximum ratings
Parameter Min Max Unit
VBAT -0.3 4.7 V
Peak current of power supply 0 2 A
RMS current of power supply (during one TDMA- frame) 0 0.7 A
Voltage at digital pins -0.3 3.3 V
Voltage at analog pins -0.3 3.0 V
Voltage at digital/analog pins in POWER DOWN mode -0.25 0.25 V
5.2. Operating temperature
The operating temperature is listed in the following table:
Table 32: Operating temperature
Parameter Min Typ Max Unit
Normal temperature -35 25 +80 ℃
Restricted operation* -45 to -35 +80 to +85 ℃
Storage temperature -45 +90 ℃
*
When the module works in this temperature range, the deviation from the GSM specification
may occur. For example, the frequency error or the phase error could increase.
