MOS INTEGRATED CIRCUIT

µPD17P236

The

µPD17P236 is a model of the µPD17236 with a one-time PROM instead of an internal mask ROM.

Since the user can write programs to the

µPD17P236, it is ideal for experimental production or small-scale

production of the

µPD17230, 17231, 17232, 17233, 17234, 17235, or 17236 systems.

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

µPD17230, 17231, 17232, 17233, 17234,

17235, and 17236.

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