STMicroelectronics M24256E-F 256-Kbit Serial I2C BUS EEPROM is organized as 32K × 8 bits, and can operate with a supply voltage from 1.65V to 5.5V. The device has a clock frequency of 1MHz (or less), over an ambient temperature range of -40°C/+85°C. The M24256E-F can also operate down to 1.6V, 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.
