GSM/GPRS/GNSS Module Series
MC60 Hardware Design
MC60_Hardware_Design Confidential / Released 83 / 99
GPRS Class 12 is the default setting. The GSM module can be configured from GPRS Class 1 to Class
12. Setting to lower GPRS class would make it easier to design the power supply for the GSM module.

1. The VCC_RF current is not reckoned in above consumption.
2. The tracking current is tested in following condition:
 For Cold Start, 10 minutes after First Fix.
 For Hot Start, 15 seconds after First Fix.
5.5. Electrostatic Discharge
Although the module is generally protected against Electrostatic Discharge (ESD), ESD protection
precautions should still be emphasized. Proper ESD handling and packaging procedures must be applied
throughout the processing, handling and operation of any applications using the module.
The measured ESD values of the module are shown in the following table.
PCS1900
@power level #0 <500mA, Typical 439mA
@power level #7, Typical 159mA
@power level #15, Typical 99mA
