CY22381FXCT datasheet by Cypress Semiconductor

CY22381FXCT Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the CY22381FXCT?
  The recommended power-up sequence is to apply VCC first, followed by VDD, and then the clock signal. This ensures proper initialization and prevents latch-up.
• How do I handle the clock signal when the device is in power-down mode?
  When the device is in power-down mode, the clock signal should be stopped or held low to prevent unnecessary power consumption and ensure proper wake-up.
• What is the maximum capacitance allowed on the clock input?
  The maximum capacitance allowed on the clock input is 20 pF. Exceeding this value may affect the clock signal integrity and device performance.
• Can I use the CY22381FXCT in a system with multiple clock domains?
  Yes, the CY22381FXCT can be used in a system with multiple clock domains, but ensure that the clock signals are properly synchronized and buffered to prevent clock domain crossing issues.
• How do I implement a clock fail-safe mechanism with the CY22381FXCT?
  Implement a clock fail-safe mechanism by using a clock supervisor or a watchdog timer to monitor the clock signal and reset the device if the clock signal is lost or corrupted.
