25LC640AXT-I/ST Frequently Asked Questions (FAQ)

  • The 25LC640AXT-I/ST has a minimum of 1 million write cycles, but the actual number of write cycles may vary depending on the usage and operating conditions.

  • To ensure data integrity, it is recommended to use the WP (Write Protect) pin to prevent accidental writes during power-down or power-up. Additionally, using a voltage supervisor or a power-on reset circuit can help prevent data corruption.

  • The recommended operating voltage range for the 25LC640AXT-I/ST is 2.5V to 5.5V. Operating the device outside of this range may affect its performance and reliability.

  • The HOLD pin should be held low during read and write operations to prevent the device from entering a low-power state. Holding the HOLD pin high will put the device in a low-power state, which may affect read and write operations.

  • The WP pin is used to prevent accidental writes to the device. When the WP pin is tied low, the device is in a write-protected state, and any write attempts will be ignored. When the WP pin is tied high, the device is in a normal operating state, and writes are allowed.
