24LC256-E/SM Frequently Asked Questions (FAQ)

  • The 24LC256-E/SM has a minimum of 1 million write cycles, but this can vary depending on the operating conditions and usage patterns.

  • The 24LC256-E/SM uses a page write buffer to handle writes. The device is organized into 128-byte pages, and writes can be performed in 1-byte increments. For block writes, the device can perform a 128-byte page write in a single operation.

  • The WP (Write Protect) pin is used to prevent writes to the entire device or a specific block of memory. When the WP pin is tied low, the entire device is write-protected. When the WP pin is tied high, the device can be written to normally.

  • The 24LC256-E/SM has a built-in power-on reset circuit that initializes the device upon power-up. During power-down, the device will automatically enter a low-power standby mode to minimize power consumption.

  • The 24LC256-E/SM has a maximum clock frequency of 1 MHz for standard operation, but this can be increased to 2 MHz for high-speed operation.
