An on-board Maxim Integrated DS3232 device provides a very accurate, temperature-compensated real-time clock (RTC) resource with:
 +
* Temperature-compensated crystal oscillator
 +
* Date, time and calendar
 +
* Alarm capability
 +
* Backup power from external battery
 +
* ±3.5ppm accuracy from -40°C to +85°C
 +
* 236 Bytes of Battery-Backed SRAM
