DS1371U+T&R Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VBAT. This ensures that the internal registers are properly initialized.
  • In the event of a dead or removed battery, the DS1371U will automatically switch to VCC power. However, it's recommended to implement a power-fail detect circuit to ensure a clean shutdown and prevent data corruption.
  • The maximum clock frequency that can be used with the DS1371U is 32.768 kHz. This is due to the internal oscillator's frequency limitation.
  • To ensure the oscillator starts up correctly, a 1-10 kΩ resistor should be connected between the X1 pin and ground. This helps to stabilize the oscillator and prevent startup issues.
  • The RST pin is an active-low reset input that can be used to reset the DS1371U. It should be tied to VCC through a 1-10 kΩ resistor and can be driven low by an external reset signal to initiate a reset.
