Features

AI Translation
  • 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
