DS1374U-33 Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DS1374U-33?
  The recommended power-up sequence is to apply VCC first, followed by VBAT. This ensures that the internal registers are properly initialized.
• How do I handle the oscillator startup time?
  The oscillator startup time is typically around 2-3 milliseconds. You can add a delay or use a reset signal to ensure that the oscillator is stable before accessing the device.
• What is the purpose of the RST pin?
  The RST pin is an active-low reset input that resets the device when pulled low. It can be used to reset the device in case of a fault or to initialize the device during power-up.
• How do I ensure that the clock output is stable?
  To ensure a stable clock output, make sure to add a load capacitor (CL) between the X1 and X2 pins, and use a suitable crystal oscillator with a frequency of 32.768 kHz.
• What is the maximum frequency for the clock output?
  The maximum frequency for the clock output is 1 Hz to 64 kHz, depending on the configuration of the device.
