描述 Description

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 of 1?MHz (or less), over an ambient temperature range of -40 °C/+85 °C. It can also operate down to 1.6 V, under some restricting conditions.

Moreover the M24256X-F offers three features.

An additional page of 64 bytes, named identification page; it can be used to store sensitive application parameters which can be (later) permanently locked in read-only mode.

A first additional 8-bit register, named the configurable device address (CDA) register authorizing the user, through software, to configure up to eight possibilities of chip enable address.

A second additional 8-bit register, named the software write protection (SWP) register authorizing the user, through software, to write protect partial or full memory array.
