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

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

  • The 24LC256-I/SM uses a page write buffer to handle writes. The device is organized into 128-byte pages, and writes can be performed in increments of 1 byte to 128 bytes. For block writes, the device can be written in blocks of 128 bytes or more.

  • 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 to VCC, the entire device is write-protected. When the WP pin is tied to a specific block address, only that block is write-protected.

  • The 24LC256-I/SM requires a specific power-up and power-down sequencing to ensure proper operation. The device should be powered up with VCC rising from 0V to the operating voltage, and powered down with VCC falling from the operating voltage to 0V.

  • The maximum clock frequency for the 24LC256-I/SM is 400 kHz for standard mode and 1 MHz for fast mode.
