Features

•

Serial real-time clock (RTC) with alarm functions

–

400 kHz I²C serial interface

–

Memory mapped registers for seconds, minutes, hours, day, date, month,

year, and century

–

Tenths/hundredths of second register

•

350 nA timekeeping current at 3 V

•

Time keeping down to 1.0 V

•

•

32 kHz crystal oscillator integrates crystal load capacitors, works with high

series resistance crystals

•

Oscillator stop detection monitors clock operation

•

Accurate programmable watchdog

–

62.5 ms to 31 minutes timeout

•

Software clock calibration. Timekeeping can be adjusted within ± 2 parts per

million (± 5 seconds per month)

•

Automatic leap year compensation

•

– 40 to + 85 °C operation

•

Two package options
