Key Features

  • Ultra-low battery supply current of 365 nA.
  • Factory-calibrated accuracy of ±5 ppm typical after 2 reflows (SOX18).
  • Much better accuracies 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).
  • M41T83.
