The STMicroelectronics 256-Kbit I2C-compatible EEPROM is 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 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. It 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. It 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.

Random and sequential read modes
Write protection of the whole memory array
Configurable device address
Enhanced ESD / latch-up protection
More than 4 million write cycles
More than 200-year data retention
