The CAT24C32WI-GT3 is an onsemi 32Kb serial EEPROM organized as 4K x 8 (4, 096 words), accessed over a two-wire I2C interface and supplied in an 8-pin SOIC package. It operates across a wide 1.7V to 5.5V supply range, which lets one part serve 1.8V, 2.5V, 3.3V and 5V systems without a level shifter, and it draws 2mA with a 3.5us access time. EEPROM is byte-erasable and byte-writable non-volatile memory, which is what makes it suitable for small parameter stores that are updated in place rather than in blocks. onsemi lists the CAT24C32WI-GT3 at Production/Active lifecycle status, lead free and RoHS compliant, rated -40C to +85C.

32Kb I2C EEPROM stores calibration data, serial numbers and MAC addresses, board and cable identification, user settings and small fault logs across industrial controllers, networking equipment, appliances, medical devices, sensor modules and automotive electronics. The 1.7V to 5.5V range is the practical differentiator, since one part number covers designs spanning several logic voltages and simplifies BOM consolidation across a product family. Buyers are embedded and industrial hardware designers, module and cable-assembly manufacturers, and contract manufacturers sourcing onsemi memory in reel or bulk volume.
