MOS INTEGRATED CIRCUIT

µPD75P218

4-BIT SINGLE-CHIP MICROCOMPUTER

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 the

µPD75218 materials.
