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 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.

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 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.
