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.

Unit

V3P3SYS and V3P3A Supply Voltage for

precision metering operation (MSN mode).

Voltages at VBAT and VBAT_RTC need

not be present.

VBAT=0 V to 3.8 V

VBAT_RTC =0 V to

3.8 V

3.0

3.6

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.

V3P3SYS < 2.8 V

and

Max (VBAT_RTC,

V3P3SYS) > 2.0 V

2.5

3.8

VBAT_RTC Voltage. VBAT_RTC is not

needed to support the RTC and non-

volatile memory unless V3P3SYS < 2.0 V

V3P3SYS<2.0 V

Operating Temperature

-40

+85

ºC

Notes:

GNDA and GNDD must be connected together.

V3P3SYS and V3P3A must be connected together.
