PD17P203A, 17P204
4-BIT SINGLE-CHIP MICROCONTROLLER WITH STATIC RAM
AND 3-CHANNEL TIMER FOR INFRARED REMOTE CONTROLLER
DESCRIPTION
碌
PD17P203A and
碌
PD17P204 are variations of
碌
PD17203A and
碌
PD17204 respectively and are equipped
with a one-time PROM instead of an internal mask ROM.
碌
PD17P203A and
碌
PD17P204 are suitable for evaluating a program when developing
碌
PD17203A and
碌
PD17204
systems respectively because the program can be written by the user.
When reading this document, also refer to the
碌
PD17203A and
碌
PD17204 Data Sheets.

PD17P203A and
碌
PD17P204 are different from
碌
PD17203A and
碌
PD17204 respectively in the power
supply voltage and the operating ambient temperature. Therefore, use
碌
PD17P203A and
碌
PD17P204
only for the system evaluation.
