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)

SO8 (M)

8-pin SOIC

■ Oscillator stop detection (monitors clock

operation)

■ Serial interface supports i c bus (400kHz

protocol)

■ Ultra-low battery supply current of 0.6μA (typ)

■ 2.0 to 5.5v clock operating voltage

SOX18 (MY)

18-pin (300mil) SOIC

with Embedded Crystal

■ Automatic switchover and deselect circuitry

(fixed reference) which provides full operation

in 3.0V applications)

■ V

= 2.7 to 5.5V

■ 2.5V ≤ V

≤ 2.7V

PFD

■ Power-down time stamp (ht bit) which allows

determination of time elapsed in battery back-

■ 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
