Product overview

Description

The M24256E-F is a 256-Kbit I²C-compatible EEPROM (electrically erasable programmable memory) organized as 32 K x 8 bits. It can operate with a supply voltage from 1.65 V to 5.5 V with a clock frequency up to 1 MHz, over an ambient temperature ranging from -40 °C to +85 °C. It can also operate down to 1.6 V under some restricting conditions.

The device offers an additional 8-bit register, called the configurable device address (CDA) register. This page authorizes the user, through software, to configure up to eight possible chip enable address.

The device also offers an additional 64-byte page, called the identification page. This page can be used to store sensitive application parameters, which can later be permanently locked in read-only mode.

On demand, the EEPROM can be delivered with a preprogrammed and locked device address.
