M41T93

Serial SPI bus RTC with battery switchover

Feature summary

■ 2.0 to 5.5V clock operating voltage

■ Ultra-low battery supply current of 365nA

■ Counters for tenths/hundredths of seconds,

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

year, and century

■ Programmable clock calibration (analog and

digital)

■ Automatic switch-over and reset output

circuitry (fixed reference)

–M41T93S: VCC = 3.0V to 5.5V

(2.85V

≤VRST ≤3.00V)

–M41T93R: VCC = 2.7V to 5.5V

(2.55V

≤VRST ≤2.70V)

–M41T93Z: VCC = 2.38V to 5.50V

(2.25V

≤VRST ≤2.38V)

■ Compatible with SPI Bus serial interface

(positive clock SPI modes)

■ Programmable alarm with interrupt function

(valid even during battery back-up mode)

■ Optional 2nd programmable alarm available

■ Square wave output (defaults to 32kHz on

power-up)

■ RESET (RST) output

■ Watchdog timer

■ Programmable 8-bit counter/timer

■ 7 Bytes of battery-backed user SRAM

■ Battery low flag

■ Power-down time stamp (HT Bit)

■ Low operating current of 80µA

■ Oscillator stop detection

■ Battery or super-cap™ Back-up

■ Operating temperature of –40°C to 85°C

■ Package options include:

– a 16-Lead QFN or an 18-Lead Embedded

Crystal SOIC
