STMicroelectronics M24M02E-U 2M-Bit I2C-Compatible EEPROM
STMicroelectronics M24M02E-U 2M-Bit I2C-Compatible EEPROM is organized as 256K x 8 bits. It can operate with a supply voltage from 1.6V to 5.5V and a clock frequency of up to 1MHz over an ambient temperature range from -40°C to +85°C. The device offers three 8-bit registers: the device type identifier (DTI) register, the configurable device address (CDA), and the software write protection (SWP) register.
The device also offers a 256-byte identification page. This additional page stores a 128-bit (16-byte) unique factory-programmed serial number, locked in read-only mode at factory delivery. The uniqueness of the serial number is ensured across the whole portfolio of serial EEPROMs manufactured by STMicroelectronics, offering a unique identifier.
