UPD17P204
Overview
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.
- 17K architecture: General-purpose register format
- Pin-compatible (except for PROM programming function): µPD17P203A with µPD17203A µPD17P204 with µPD17204
- Internal one-time PROM: 4096 x 16 bits (µPD17P203A) 7936 x 16 bits (µPD17P204)
- Static RAM: 16 Kbits (µPD17P203A) 8 Kbits (µPD17P204)
- Power supply voltage: 2.9 to 5.5 V (at TA = -20 to +75°C, fX = 4MHz) 2.0 to 5.5 V (at TA = -20 to +75°C, fXT = 32kHz) The features of each product is shown in the following table: Item Pull-up resistor of RESET pin Pull-up resistor of P0A and P0B pins Main clock oscillator circuit Subclock oscillator circuit µPD17P203A-001 µPD17P204-001 µPD17P203A-002 µPD17P204-002 Not provided Provided Not provided µPD17P203A-003 µPD17P204-003 Not provided Provided µPD17203A µPD17204 On request (mask option) Provided 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. This document explains µPD17P204 as a typical product where no specification is made.
