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
- I²C Interface
Backup power is provided through the RTC_VBAT signal:
- on Bora it is connected to J2.113
- on Bora Lite it is connected to J1.22
If not used, RTC_VBAT must be externally connected to GND. For a detailed description of RTC characteristics, please refer to the DS3232 datasheet.
