Datasheet

– Hibernation clock input failure detect with a switch to the internal oscillator on detection

■ RTC operational and hibernation memory valid as long as V

or V

BAT

is valid

■ Low-battery detection, signaling, and interrupt generation, with optional wake on low battery

■ GPIO pin state can be retained during hibernation

■ Clock source from an internal low frequency oscillator (HIB LFIOSC) or a 32.768-kHz external

crystal or oscillator

■ Sixteen 32-bit words of battery-backed memory to save state during hibernation

■ Programmable interrupts for:

– RTC match

– External wake

– Low battery
