M41T81
Serial access real-time clock with alarm
Features
For all new designs other than automotive, use
M41T81S (contact the ST sales office for
automotive grade)
Counters for tenths/hundredths of seconds,
seconds, minutes, hours, day, date, month,
year, and century
32 KHz crystal oscillator integrating load
capacitance (12.5 pF) providing exceptional
oscillator stability and high crystal series
resistance operation
Serial interface supports I2C bus (400 kHz
protocol)
Ultra-low battery supply current of 0.6 A
(typ at 3 V)
2.0 to 5.5 V clock operating voltage
Automatic switch-over and deselect circuitry
(for 3 V application select M41T81S datasheet)
Power-down time stamp (HT bit) allowing
determination of time elapsed in battery
backup
Programmable alarm and interrupt function
(valid even during battery backup mode)
Accurate programmable watchdog timer (from
62.5 ms to 128 s)
Software clock calibration to compensate
crystal deviation due to temperature
Operating temperature of –40 to 85 °C
ECOPACK package available
