UPD17P218 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.
