M41T81S
Serial access real-time clock with alarms
Features
■
Counters for tenths/hundredths of seconds,
seconds, minutes, hours, day, date, month,
year, and century
■
32KHz crystal oscillator with integrated load
capacitance (12.5pf) which provides
exceptional oscillator stability and high crystal
series resistance operation)
■
Oscillator stop detection (monitors clock
operation)
■
Serial interface supports i

c bus (400kHz
protocol)
■
Ultra-low battery supply current of 0.6
μ
A (typ)
■
2.0 to 5.5v clock operating voltage
■
Automatic switchover and deselect circuitry
(fixed reference) which provides full operation
in 3.0V applications)

■
Power-down time stamp (ht bit) which allows
determination of time elapsed in battery back-
up
■
Battery low flag
■
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 for
crystal deviation due to temperature)
■
Operating temperature of –40 to 85°C
■
Package options include an 8-lead SOIC or 18-
lead embedded crystal SOIC
