Serial access Real-Time Clock with alarm

Feature summary

■ Counters for tenths/hundredths of seconds,

seconds, minutes, hours, day, date, month,

year, and century

■ 32KHz crystal oscillator integrating load

capacitance (12.5pF) providing exceptional

oscillator stability and high crystal series

resistance operation

■ Serial interface supports I C bus (400kHz

protocol)

SO8 (M)

8-pin SOIC

■ Ultra-low battery supply current of 0.6µA

(typ@3V)

■ 2.0 to 5.5V clock operating voltage

■ Automatic switch-over and deselect circuitry

(for 3V application select M41T81S data sheet)

■ Power-down time stamp (HT bit) allowing

determination of time elapsed in battery back

■ Programmable alarm and interrupt function

(valid even during battery back-up mode)

■ Accurate programmable watchdog timer (from

62.5ms to 128s)

■ Software clock calibration to compensate

crystal deviation due to temperature

■ Operating temperature of –40 to 85°C

■ ECOPACK® package available
