M41T56

Serial Real Time Clock with 56 bytes NVRAM

Feature summary

■

Counters for seconds, minutes, hours, day,

date, month, years, and century

■

32 KHz crystal oscillator integrating load

capacitance (12.5pF) providing exceptional

oscillator stability and high crystal series

resistance operation

■

Serial interface supports I2C Bus (400kHz

protocol)

■

Ultra-low battery supply current of 450nA

(typ@3V)

■

5V ±10% supply voltage

■

Timekeeping down to 2.5V

■

Automatic power-fail detect and switch circuitry

■

56 bytes of general purpose RAM

■

Software clock calibration to compensate

crystal deviation due to temperature

■

Automatic leap year compensation

■

Operating temperature of –40 to 85°C

■

Packaging options include:

– 28-lead SOIC and SNAPHAT® TOP (to be

ordered separately)
