DATA SHEET
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.
Note Under development
FEATURES
