PDF reference of 112 KB covering the 24LC01 and 24LC02 serial EEPROMs, 1 Kbit and 2 Kbit two-wire memories sharing a common pinout. Despite the schematic label, it is a component datasheet describing addressing, write timing, endurance and voltage range. Technicians use it when servicing equipment that keeps settings or IDs in these chips, for checking the SDA and SCL lines, WP pin and supply, and for selecting the right capacity in programmer software. Confirm the actual marking on the IC before reading or writing.
