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 28: Absolute maximum ratings
Parameter
VBAT
Peak current of power supply
RMS current of power supply (during one TDMA-
frame)
Voltage at digital pins
Voltage at analog pins
Voltage at digital/analog pins in POWER DOWN mode

5.2. Operating temperature

The operating temperature is listed in the following table:

When the module works in the temperature range, the deviation from the GSM specification
may occur. For example, the frequency error or the phase error could increase.
