25LC640AT-E/SN Frequently Asked Questions (FAQ)
-
The 25LC640AT-E/SN 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, the device has built-in power-on reset and brown-out detection to prevent data corruption.
-
The recommended operating voltage range for the 25LC640AT-E/SN is 2.5V to 5.5V, with a typical operating voltage of 3.3V or 5V.
-
The HOLD pin is used to pause the serial communication during device operation. When the HOLD pin is low, the device will pause the serial communication and will resume when the HOLD pin is high.
-
The WP (Write Protect) pin is used to prevent accidental writes to the device. When the WP pin is low, the device is in write-protect mode, and no writes are allowed.
