UPD75P218 Overview
DATA SHEET MOS INTEGRATED CIRCUIT µPD75P218 4-BIT SINGLE-CHIP MICROPUTER The µPD75P218 is a one-time PROM version that can be written to only once or an EPROM version that allows program writing, erasing, and rewriting, of the µPD75218 Note. Since the program can be written by the user, the µPD75P218 is suitable for preproduction use during system development, or limited production. Read this material together with...
