PDF reference, 112 KB, for the 24C64 serial EEPROM, a 64 Kbit two-wire memory widely used in consumer and automotive electronics. The name gives no package or revision, and although catalogued as a schematic it is component documentation. It typically covers pin assignment, two-byte addressing, 32-byte page writes and voltage ranges. Technicians rely on it to check the chip circuit, confirm the WP pin state and configure a programmer for reading or restoring data. Dumps must be 8 KB to fit; save the original first.
