  • Maintains the real time, even when the device is off (powered-off).
  • Has the capability to generate an alarm at a specific time and date.
  • Includes the means for periodic software calibration of the RTC.
  • Includes logic to correct the static fractional inaccuracy of the oscillator.
  • Keeps track of time within a window of more than 136 years (232 seconds) from a reference point.
  • Implemented as three counters.
  • 16-bit tick counter creates one second based on the crystal clock.
  • 4-bit fraction counter keeps track of the static crystal errors in one second that is less than one oscillator tick.
  • 32-bit seconds counter holds the real time and allows on-demand reload whenever current time of the RTC is set.
  • Allows wake-up at a specific second within the 136 years (32-bit alarm)
