Backup Voltage (Real-Time-
Clock)
VBACKUP Backup Voltage for Real-Time-Clock 2.7 3.0 4.5 Vdc
IBACKUP Input Current (VBACKUP = 3.2 V, VBAT = 0 V, No Load on GPIO or
Serial Port)
3.0 6.0 mAdc
VBACKUP had been tested in the above scenarios and does not contribute to leakage. It will
properly provide backup power to the RTC clock.
KHZ Output (Pin 56)
A 32.768 kHz signal is available as an output from the module. This signal should only be used
as an input to a high impedance device. Additional loads or capacitance on the line may cause
performance issues with the module. If the line is not used, leave floating.
