Power is supplied to the wireless modem VCC pins, from an external source.
User application circuitry should connect all VCC pins together in to carry the current
drawn by the wireless modem.
The electrical characteristics for VCC are shown in the following table.
Parameter Mode Limit
Nominal 3.6 V
Min 3.2 V
Max 4.5 V
Absolute maximum limit -0.3V to 6.5V
VCC Supply voltage
Maximum supply ripple
<100mV @<200kHz
<20mV @>200kHz
Maximum allowable voltage drop Transmission burst 200mV
2100 mA peak
Maximum current consumed Full power (2W) transmit
340 mA average
Stresses in excess of the absolute maximum limits can cause permanent
damage to the device. These are absolute stress ratings only. Functional
operation of the device is not implied at these or any other conditions in
excess of those given in the normal Min & Max values stated. Exposure
to absolute maximum ratings for extended periods can adversely affect
device reliability.
