DS3234S#T&R 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.
  • Use a battery-backed VCC pin (VBAT) to maintain the RTC's timekeeping during power failures. The DS3234S has a built-in battery switch that automatically switches to the battery when the main power supply (VCC) fails.
  • Yes, the DS3234S can generate a 1Hz to 32kHz clock signal on its SQW pin, which can be used as a clock source for a microcontroller.
  • Use the I2C interface to set the RTC's registers to the desired date and time. The DS3234S has a set of registers that store the seconds, minutes, hours, day, month, and year, which can be written to using the I2C protocol.
  • The EOSC (Enable Oscillator) pin is used to enable or disable the internal oscillator. When EOSC is low, the oscillator is enabled, and when it's high, the oscillator is disabled.
