M41T256Y

256Kbit (32K x 8) serial RTC

Features

■ 5V operating voltage

■ Serial interface supports extended I2C bus

addressing (400kHz)

■ Automatic switchover and deselect circuitry

■ Power-fail deselect voltages:

–M41T256Y: VCC = 4.5 V to 5.5V;

VPFD = 4.2V < VPFD < 4.5V

■ Counters for tenths/hundredths of seconds,

seconds, minutes, hours, day, date, month,

and year

■ Programmable software clock calibration

■ 32,752 bytes of general purpose RAM

■ Microprocessor power-on reset

■ Holds microprocessor in reset until supply

voltage reaches stable operating level

■ Automatic address-incrementing

■ Tamper indication circuit with time-stamp

■ Sleep mode function

■ Available in ST’s 44-lead SNAPHAT® SOIC -

mates with ST’s removable/replaceable

SNAPHAT® battery/crystal top (ordered

separately)

■ RoHS compliant

– Lead-free second level interconnect
