Key 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 2ndprogrammable 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
