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.
The NEC uPD17P203A and uPD17P204 are 4‑bit single‑chip microcontrollers designed for infrared remote‑control applications. They integrate static RAM, a one‑time programmable PROM, and three timer channels, and are supplied in a 52‑pin plastic QFP package.
The document provides pin configurations, electrical specifications, programming procedures for the one‑time PROM, and handling guidelines for CMOS devices. It also includes ordering information, package drawings, and recommended soldering conditions.
