M41T93

Serial SPI bus RTC with battery switchover

Features

■ Ultra-low battery supply current of 365nA

■ Factory calibrated accuracy 5PPM

guaranteed after 2 reflows (SOX18)

– Much better accuracies achievable using

built-in programmable analog and digital

calibration circuits

QFN16, 4mm x 4mm (QA)

■ 2.0V to 5.5V clock operating voltage

■ Counters for tenths/hundredths of seconds,

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

year, and century

SOX18 (MY, 18-pin, 300mil SOIC

with embedded crystal)

■ Automatic switch-over and reset output

circuitry (fixed reference)

– M41T93S: V = 3.0V to 5.5V

(2.85V ≤ V

≤ 3.00V)

RST

– M41T93R: V = 2.7V to 5.5V

(2.55V ≤ V

– M41T93Z: V = 2.38V to 5.50V

≤ 2.70V)

RST

■ Package options include:

– a 16-lead QFN or an 18-lead embedded

crystal SOIC

(2.25V ≤ V

≤ 2.38V)

RST

■ Compatible with SPI bus serial interface

■ RoHS compliance: lead-free components are

(positive clock SPI modes)

compliant with the RoHS directive

■ Programmable alarm with interrupt function

(valid even during battery back-up mode)

■ Optional 2 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
