MOS INTEGRATED CIRCUIT

µPD17P218

DESCRIPTION

The

µPD17P218 is a model of the µPD17218 with a one-time PROM instead of an internal mask ROM.

Since the user can write programs to the

µPD17P218, it is ideal for experimental production or small-scale

production of the

µPD17215, 17216, 17217 or 17218 systems.

When reading this document, also read the documents related to the

µPD17215, 17216, 17217 and 17218.

Detailed functions are described in the following user’s manual. Read this manual when designing your

system.

µPD172×× Series User’s Manual: IEU-1317
