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.

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.
