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

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

  • The 24LC256-E/MF uses a page write buffer that allows for efficient writing of data in 64-byte increments. For block writes, you can use the page write buffer to write data in 64-byte chunks, and then use the internal address counter to automatically increment the address for each subsequent write.

  • The recommended clock frequency for the 24LC256-E/MF is up to 400 kHz for the -E version and up to 1 MHz for the -M version. However, the actual clock frequency may vary depending on the specific application and operating conditions.

  • The 24LC256-E/MF has a built-in power-on reset circuit that initializes the device to a known state. For power-down sequencing, it is recommended to disable the clock signal before powering down the device to prevent any unwanted writes or corruption of data.

  • The 24LC256-E/MF has a minimum data retention period of 200 years at a temperature of 25°C, and 100 years at a temperature of 55°C. However, this can vary depending on the operating conditions and usage patterns.
