DS3231M+ Frequently Asked Questions (FAQs)

  • The internal oscillator has an accuracy of ±2 ppm from 0°C to 40°C, and ±3 ppm from -40°C to 85°C.
  • You need to write the desired date and time to the timekeeping registers (00h-07h) using the I2C interface. The device will then start counting from the set date and time.
  • The EOSC (Enable Oscillator) pin is used to enable or disable the internal oscillator. When EOSC is high, the oscillator is enabled, and when it's low, the oscillator is disabled.
  • The alarm functions can be used to trigger an interrupt when a specific date and time is reached. You need to set the alarm registers (0Ah-0Fh) with the desired date and time, and enable the alarm interrupt using the control registers (0Eh-0Fh).
  • The SQW (Square Wave) pin can output a square wave at a frequency of up to 32.768 kHz.
