UPD17P203A
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.
µPD17P203A and µPD17P204 are suitable for evaluating a program when developing µPD17203A and 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.
FEATURES
