5.2 Absolute maximum ratings
Absolute maximum rating for power supply and voltage on digital and analog pins of module are
listed in the following table:
Table 32: Absolute maximum ratings
Parameter Min Max Unit
VBAT 0 4.7 V
Peak current of power supply 0 3 A
RMS current of power supply (during one TDMA- frame) 0 0.7 A
Voltage at digit pins -0.3 3.3 V
Voltage at analog pins -0.3 3.0 V
Voltage at digit/analog pins in POWER DOWN mode -0.25 0.25 V
5.3 Operating temperatures
The operating temperature is listed in the following table:
Table 33: 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 deviations from the GSM specification
may occur. For example, the frequency error or the phase error could increase.
