DESCRIPTION

µPD17P203A and µPD17P204 are variations of µPD17203A and µPD17204 respectively and are equipped

with a one-time PROM instead of an internal mask ROM.

µPD17P203AandµPD17P204aresuitableforevaluatingaprogramwhendevelopingµPD17203Aand µPD17204

systems respectively because the program can be written by the user.

When reading this document, also refer to the

µPD17203A and µPD17204 Data Sheets.

µPD17P203A and µPD17P204 are different from µPD17203A and µPD17204 respectively in the power

supply voltage and the operating ambient temperature. Therefore, use

µPD17P203A and µPD17P204

only for the system evaluation.
