描述 Description

The M24256E-F is a 256-Kbit I2C-compatible EEPROM (electrically erasable programmable read only memory) organized as 32 K × 8?bits.

The M24256E-F can operate with a supply voltage from 1.65?V to 5.5?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.

The M24256E-F offers an additional page of 64 bytes, named identification page, which can be used to store sensitive application parameters which can be (later) permanently locked in read-only mode.

The M24256E-F offers also an 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.

On demand, the eeprom can be delivered by STMicroelectronics with a preprogrammed and locked device address (001).
