Description

The M41T81SMY6T is a low power Serial RTC with a built-in 32.768kHz oscillator (external crystal controlled). Eight bytes of the SRAM M41T81SMY6T are used for the clock/calendar function and are configured in binary coded decimal (BCD) format.

The features of M41T81SMY6T can be summarized as (1)counters for tenths/hundredths of seconds, seconds, minutes, hours, day, date, month, year, and century; (2)32khz crystal oscillator with integrated load capacitance (12.5pf) which provides exceptional oscillator stability and high crystal series resistance operation); (3)oscillator stop detection (monitors clock operation); (4)serial interface supports i2c bus (400khz protocol); (5)ultra-low battery supply current of 0.6a (typ); (6)2.0 to 5.5v clock operating voltage; (7)power-down time stamp (ht bit) which allows determination of time elapsed in battery back-up; (8)battery low flag; (9)programmable alarm and interrupt function (valid even during battery back-up mode); (10)accurate programmable watchdog timer (from 62.5ms to 128s); (11)software clock calibration (to compensate for crystal deviation due to temperature); (12)operating temperature of 40 to 85°c; (13)package options include an 8-lead soic or 18-lead embedded crystal soic.

The absolute maximum ratings of M41T81SMY6T are:(1)Storage Temperature (VCC Off, Oscillator Off):55 °C to 125 °C; (2)Supply Voltage:0.3V to 7 V; (3)Lead Solder Temperature for 10 Seconds:Lead-free lead finish..260 °C,Standard (SnPb) lead finish..240 °C; (4)Input or Output Voltages:0.3V to Vcc+0.3 V; (5)Output Current:20 mA; (6)Power Dissipation:1 W.
