DS1372U+ 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 and the device operates correctly.
  • In this case, the device will automatically switch to battery-backed mode, and the internal registers will be maintained. However, it's recommended to ensure that VBAT is always higher than or equal to VCC to prevent any potential issues.
  • The RST pin is an active-low reset input that resets the device and clears all registers. It can be used to reset the device in case of a fault or to initialize the device during power-up. A low pulse on the RST pin (typically 1-2 ms) is required to reset the device.
  • To ensure accurate timekeeping, it's essential to use a high-quality crystal oscillator and to follow the recommended crystal loading and layout guidelines. Additionally, the device should be calibrated periodically to account for any crystal frequency deviations.
  • The maximum allowed capacitance on the X1 and X2 pins is 15 pF. Exceeding this limit can affect the oscillator's start-up time and frequency stability, leading to inaccurate timekeeping. It's essential to follow the recommended layout and component selection guidelines to ensure reliable operation.
