PDF datasheet of 338 KB covering the 24AA01 and 24LC01B, the 1 Kbit members of this I2C serial EEPROM line. It gives the pinout, electrical limits, addressing, page write details and timing diagrams. Technicians use such a sheet to identify a small eight-pin memory found on a board, verify its supply and bus lines, and read or replace it with a programmer. Check the marking on the chip against these part numbers, and keep a backup of whatever data it holds before writing or swapping it.
