38 Copernicus GPS Receiver
Normal Operating Conditions
Minimum and maximum limits apply over full operating temperature range unless
otherwise noted.
* The rise time to VCC MUST be greater than 140 μsecs. The user can use one source of power on Pin 12 (VCC) for both
main and Standby power.
** If using two sources of power, the Main and Standby power must be connected to VCC via an external diode-pair.
During the Standby Mode, the main power can be removed so the unit can be run on Standby power. Standby power
must be at least 0.3V less than main power. The voltage at Pin 12 must be 2.7V to 3.3V including the diode voltage drop.
(See Chapter 5 for information on application circuits.)
