The onsemi CAT24C512WI-GT3 is a 512kb serial EEPROM organised as 64K x 8 and accessed over a 2-wire I2C interface. It operates from 1.8V to 5.5V, supports bus clock rates up to 400 kilohertz, and has an access time of 3.5µs. The CAT24C512WI-GT3 is supplied in an 8-pin SOIC surface-mount package on tape and reel and is specified from -40°C to 85°C.

Serial EEPROM is byte-alterable non-volatile memory, so it holds the small quantities of data that must survive a power cycle and still be rewritten in place: calibration constants, serial numbers, configuration settings, and event counters. The 1.8V to 5.5V range and I2C interface let the CAT24C512WI-GT3 sit alongside almost any microcontroller without level translation, and the -40°C to 85°C rating covers industrial instrumentation, networking, and appliance designs. The 8-pin SOIC body is chosen where inspection and rework matter more than board area. Typical users are embedded designers in industrial control, consumer appliances, and communications hardware.
