The M24256X-F is a 256-Kbit I2C-compatible EEPROM (electrically erasable programmable memory) organized as 32 K × 8 bits.

The M24256X-F can operate with a supply voltage from 1.65 V to 3.6 V, with a clock frequency up to 1 MHz, over an ambient temperature range from -40 °C to +85 °C. It can also operate down to 1.6 V, under some restricting conditions.

The M24256X-F offers three additional features, namely a 64-byte page, named identification page, which can be used to store sensitive application parameters that can be (later) permanently locked in read-only mode, a first 8-bit register, named configurable device address (CDA) register, authorizing the user, through software, to configure up to eight possibilities of chip enable address, and a second 8-bit register, named software write protection (SWP) register, authorizing the user, through software, to write protect a part or the full memory array.
