Indexed as a schematic, this 107 KB PDF covers the Microchip 24LC65, a 64 Kbit Smart Serial I2C EEPROM, and is effectively its datasheet. The Smart Serial parts include features such as a high-endurance block and configurable write protection, described here alongside pinout, addressing and timing. A technician refers to it to select the correct chip type in a programmer, check how address pins are tied on the board and read or replace stored data. Back up the existing contents before any erase or write.
