Key features
  • Counters for tenths/hundredths of seconds, seconds, minutes, hours, day, date, month, year, and century
  • 32 KHz crystal oscillator with integrated load capacitance (12.5 pf) which provides exceptional oscillator stability and high crystal series resistance operation)
  • Oscillator stop detection (monitors clock operation)
  • Serial interface supports I2C bus (400 kHz protocol)
  • Ultra-low battery supply current of 0.6 μA (typ)
  • 2.0 to 5.5 V clock operating voltage
  • Automatic switchover and deselect circuitry (fixed reference) which provides full operation in 3.0 V applications)
  • VCC= 2.7 to 5.5 V
  • 2.5 V ≤ VPFD≤ 2.7 V
  • Power-down time-stamp (HT bit) which allows determination of time elapsed in battery backup
  • Battery low flag
  • Programmable alarm and interrupt function (valid even during battery backup mode)
  • Accurate programmable watchdog timer (from 62.5 ms to 128 s)
  • Software clock calibration (to compensate for crystal deviation due to temperature)
  • Operating temperature of –40 to 85 °C
  • Package options include an 8-lead SOIC or 18-lead embedded crystal SOIC
