PDF datasheet of 460 KB for the 93C65A, a 93-series serial EEPROM using the three-wire Microwire interface, filed under schematics. The file name does not state the vendor, so density, organisation and voltage specifics should be read from the sheet itself. Such EEPROMs typically keep configuration and calibration data in consumer and industrial electronics. Before reading or rewriting one, look up the pinout and organisation mode here, set the programmer accordingly and keep a backup of the original data in case the write fails.
