MOS INTEGRATED CIRCUIT
µPD17P203A, 17P204
4-BIT SINGLE-CHIP MICROCONTROLLER WITH STATIC RAM AND 3-CHANNEL TIMER FOR INFRARED REMOTE CONTROLLER
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
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:
