CY23EP09ZXI-1HT datasheet by Cypress Semiconductor

CY23EP09ZXI-1HT Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for CY23EP09ZXI-1HT?
  The recommended operating voltage range for CY23EP09ZXI-1HT is 2.7V to 3.6V, although it can operate from 2.3V to 3.6V with reduced performance.
• How do I implement a clock signal for the CY23EP09ZXI-1HT?
  The CY23EP09ZXI-1HT requires an external clock signal, which can be generated using a crystal oscillator or an external clock source. The clock frequency should be within the specified range of 1 MHz to 33 MHz.
• What is the maximum frequency for the I2C interface on the CY23EP09ZXI-1HT?
  The maximum frequency for the I2C interface on the CY23EP09ZXI-1HT is 400 kHz, although it can operate at higher frequencies with reduced performance.
• How do I handle power-up and power-down sequencing for the CY23EP09ZXI-1HT?
  It is recommended to power up the VDD pin before the VDDQ pin, and power down the VDDQ pin before the VDD pin to ensure proper operation and prevent latch-up.
• What is the purpose of the WP pin on the CY23EP09ZXI-1HT?
  The WP (Write Protect) pin is used to prevent accidental writes to the device. When the WP pin is tied low, the device is in write-protect mode, and when it is tied high, the device is in normal operation mode.
