25LC640A-I/SN Frequently Asked Questions (FAQ)
-
The 25LC640A-I/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 25LC640A-I/SN is 2.5V to 5.5V, with a typical operating voltage of 3.3V or 5V.
-
The HOLD pin should be tied to VCC or left floating during normal operation. When the HOLD pin is low, the device will be in a 'hold' state, and all inputs will be ignored.
-
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.
