I2C (2-wire) Serial EEPROMs

Microchip I2C (2-wire) Serial EEPROMs are compatible byte and page writable Serial EEPROMs designed to provide simple, yet flexible data storage for microcontroller, microprocessor, and SoC solutions. Devices have ultra-high write endurance capabilities allowing for greater than 1 million write cycles to each and every memory location to meet the needs of today’s high write endurance applications. These new devices include a factory-programmed 128-bit serial number which does not consume any of the user read/write area.
