RTC Backup 

The module uses RTC (Real Time Clock) to update and maintain inherent time at no VBAT power supply 
status.  The RTC power supply of module can be provided by an external capacitor or a battery 
(non-chargeable or rechargeable) through the VRTC. The following figures show various reference circuits 
for RTC back up. The discharge current is less than 10uA.
