DS3234S# 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 corresponding registers (seconds, minutes, hours, day, date, month, and year) in the correct format (BCD or binary, depending on the mode). Then, set the OSF (oscillator stop flag) bit to 0 to start the clock.
  • The VBAT pin is used to connect a backup battery, which maintains the clock's operation and retains the time and alarm settings when the main power supply (VCC) is interrupted or removed.
  • You need to set the alarm registers (AL1-AL4) to the desired values, enable the alarm interrupt (AIE) bit, and configure the interrupt output (INT/SQW) pin to output a signal when the alarm matches the current time.
  • The maximum frequency of the SQW/INT output is 32.768 kHz, which is the same as the crystal oscillator frequency.
