Product overview
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.
