The onsemi CAT24C64WI-GT3 is a 64kb serial EEPROM with an I2C interface, organized as 8kB of user memory across 8, 000 words. EEPROM is byte-alterable non-volatile memory that retains data without power and can be rewritten in place, which makes the CAT24C64WI-GT3 suitable for configuration and calibration storage. It operates from a wide 1.7V to 5.5V supply at up to 400k Hz, draws a nominal 2mA, and offers a 900ns access time. The device is supplied in an 8-pin SOIC package with gold contact plating on tape and reel, is lead free and RoHS compliant, and is rated from -40C to 85C.

Serial EEPROMs like the CAT24C64WI-GT3 are used to hold small blocks of data that must survive power cycles: board serial numbers, calibration constants, user settings, sensor trim values and event counters. The 1.7V to 5.5V supply range lets one part serve 1.8V, 2.5V, 3.3V and 5V rails without translation, and the -40C to 85C range covers industrial as well as commercial environments. Design engineers, contract manufacturers and industrial OEMs specify parts in this class wherever an I2C host controller needs a small, low-pin-count non-volatile store alongside the main processor.
