Description
M24256-DFMN6TP is a 256-kilobit serial EEPROM memory IC used for non-volatile data storage in embedded systems. It provides byte-addressable read/write with support for page writes and is typically accessed over an I2C-compatible serial bus. The device is organized as about 32K × 8 (32K bytes) of memory, enabling storage of configuration data, calibration constants, small logs, and similar data. It comes in an 8-pin package suitable for cost-sensitive, low-pin-count designs. Address pins on the package allow multiple devices on the same I2C bus. Temperature and voltage ranges, timing parameters, and the exact package variant depend on the manufacturer revision; consult the official datasheet for precise specifications, pinout, and operating conditions.
