DS1305E+ Frequently Asked Questions (FAQs)

  • The recommended crystal oscillator frequency for the DS1305E+ is 32.768 kHz, which is a standard frequency for real-time clocks.
  • The DS1305E+ has a built-in battery switchover circuit that automatically switches to the backup battery during power failure, ensuring continuous operation of the real-time clock.
  • The maximum backup battery life for the DS1305E+ depends on the battery type and capacity, but typically ranges from 5 to 10 years, assuming a 48mAh battery and a trickle charge current of 1μA.
  • Yes, the DS1305E+ can be used in a 5V system, but it requires an external voltage regulator to regulate the voltage to 3V, which is the maximum operating voltage for the device.
  • The DS1305E+ automatically handles leap year corrections, taking into account the rules for leap years, including century years that are divisible by 400.
