Range datasheet in a 63.4 KB PDF for the Catalyst 24WC01 through 24WC16, a family of small two-wire serial EEPROMs, although the index files it as a schematic. One document covers several capacities, so pay attention to the tables that show which address pins are used and how memory blocks are selected on each size. Technicians rely on it to identify the exact density on a board, configure a programmer correctly and verify SDA and SCL signals. Read and save the chip before any erase.
