Features

 Ultra-low battery supply current of 365 nA

 Factory calibrated accuracy ±5 ppm typical

after 2 reflows (SOX18) (much better

accuracies are achievable using built-in

programmable analog and digital calibration

circuits)

 2.0 V to 5.5 V clock operating voltage

 Counters for tenths/hundredths of seconds,

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

year, and century

 Automatic switchover and reset output circuitry

(fixed reference):

M41T93S: VCC = 3.0 V to 5.5 V;

M41T93R: VCC = 2.7 V to 5.5 V;

M41T93Z: VCC = 2.38 V to 5.50 V

 Compatible with SPI bus serial interface

(supports SPI mode 0 [CPOL = 0, CPHA = 0])

 Programmable alarm with interrupt function

(valid even during battery backup mode)

 Optional 2nd programmable alarm available

 Square wave output (defaults to 32 KHz on

power-up)

 RESET (RST) output

 Watchdog timer

 Programmable 8-bit counter/timer

 7 bytes of battery-backed user SRAM

 Battery low flag

 Low operating current of 80 μA

 Oscillator stop detection

 Battery or supercapacitor backup

 Operating temperature of –40 °C to +85 °C

 Package options include a 16-lead QFN and an

18-lead embedded crystal SOIC
