DS1302Z+T&R Frequently Asked Questions (FAQ)

  • A simple RC circuit with a 1kΩ resistor and a 10μF capacitor can be used to provide a power-on reset signal to the DS1302. This ensures that the device is properly reset during power-up.

  • When the power is interrupted, the BBRAM contents are retained as long as the battery voltage remains above 1.5V. To ensure data integrity, it's recommended to stop writing to the BBRAM before power-down and to avoid accessing it during power-up until the device is fully powered.

  • The maximum clock frequency for the DS1302 is 32.768 kHz, which is the typical frequency for a 32.768 kHz crystal oscillator.

  • The DS1302 can be synchronized with an external clock source by applying the external clock signal to the CLKIN pin. The device will then synchronize its internal clock with the external clock signal.

  • The EOSC (End of Shutdown) pin is an output that goes high when the device is fully powered up and the oscillator is stable. It can be used to reset external circuits or to indicate that the device is ready for operation.
