Datasheet PDF of about 100 KB for the 24LC02 serial EEPROM, a small 2 Kbit memory with an I2C interface. The name gives only the base part number. This chip often holds configuration bytes, SPD data on older memory modules or settings in TVs and peripherals. The document covers pinout, address pins A0 to A2, page write behaviour and voltage limits. Technicians use it to check that pull-ups and the write-protect pin are correct and to select the proper type in programmer software. Save the original dump before modifying contents.
