25LC640AT-I/ST Frequently Asked Questions (FAQ)
-
The 25LC640AT-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 25LC640AT-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 tied to VCC or left floating during normal operation. Tying the HOLD pin to GND will put the device in a low-power standby mode, and it should only be done when the device is not being accessed.
-
The WP pin is used to prevent writes to the device when it is tied to GND. When WP is tied to VCC, the device is in a normal operating mode, and writes are allowed. When WP is tied to GND, the device is in a write-protected mode, and writes are inhibited.
