M24256X-GCU6T/VF 256-Kbit serial I2C bus EEPROM

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

The M24256X-G can operate with a supply voltage of 1.8 V ± 5% (from 1.71 V to 1.89 V), with a clock frequency of 1 MHz (or less), over an ambient temperature range of -40 °C/+85 °C.

The M24256X-G product offers the I/Os compatible with 1.2 V and delivery in a 4-pin package.

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