23K640-E/ST Frequently Asked Questions (FAQ)

  • The maximum operating frequency of the 23K640-E/ST is 20 MHz.

  • The HOLD pin should be pulled high during power-up and power-down to prevent unwanted writes to the device. It's recommended to use a pull-up resistor to ensure the pin is held high during these transitions.

  • The recommended voltage range for the VCC pin is 2.7V to 3.6V. Operating the device outside of this range may affect its performance and reliability.

  • To implement a reliable write protection mechanism, use the WP pin to enable or disable write operations. When the WP pin is low, the device is in write-protect mode, and any write attempts will be ignored. You can also use the WPEN bit in the Status Register to enable or disable write protection.

  • The PROTECT pin is used to protect the device from accidental writes during power-up or power-down. When the PROTECT pin is low, the device is in a protected state, and any write attempts will be ignored. This pin should be pulled high during normal operation.
