Parameter
V3P3SYS and V3P3A Supply Voltage for precision
metering operation (MSN mode). Voltages at
VBAT and VBAT_RTC need not be present.
VBAT Voltage (BRN mode). V3P3SYS is below
the 2.8 V comparator threshold. Either V3P3SYS
or VBAT_RTC must be high enough to power the
RTC module.
VBAT_RTC Voltage. VBAT_RTC is not needed to
support the RTC and non-volatile memory unless
V3P3SYS<2.0 V

32.768 kHz crystal – electrically
equivalent to ECS .327-12.5-17X or
Vishay XT26T, load capacitance 12.5 pF
Load capacitor values for crystal depend
on crystal specifications and board
parasitics. Nominal values are based on
4 pF board capacitance and include an
allowance for chip capacitance.
