STMicroelectronics M24256X-GCU6T/VF, 32 kB EEPROM 4-Pin WLCSP I2C

The STMicroelectronics 256-Kbit I2C-compatible EEPROM (electrically erasable programmable memory) organized as 32 K x 8 bits. It 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.
