DS1302ZN+T&R Frequently Asked Questions (FAQs)

  • A 0.1uF capacitor and a 1kΩ resistor in series can be used to create a power-on reset circuit for the DS1302. This ensures that the device is properly reset during power-up.
  • During power-down, the BBRAM contents are retained as long as the battery voltage remains above 2.0V. It's recommended to use a battery with a capacity of at least 48mAh to ensure data retention for at least 10 years.
  • The maximum clock frequency for the DS1302 is 32.768 kHz, which is the typical frequency for a 32.768 kHz crystal oscillator.
  • To ensure accurate timekeeping, use a high-quality 32.768 kHz crystal oscillator, and trim the oscillator circuit to minimize frequency error. Also, ensure that the device is operated within the recommended temperature range.
  • No, the DS1302 is not designed to work with lithium-ion batteries. It's recommended to use a 3V lithium coin cell battery, such as the CR2032, which has a stable voltage output and a long shelf life.
