PD17P236
4-BIT SINGLE-CHIP MICROCONTROLLER
FOR SMALL GENERAL-PURPOSE INFRARED
REMOTE CONTROLLER
The
碌
PD17P236 is a model of the
碌
PD17236 with a one-time PROM instead of an internal mask ROM.
Since the user can write programs to the
碌
PD17P236, it is ideal for experimental production or small-scale
production of the
碌
PD17230, 17231, 17232, 17233, 17234, 17235, or 17236 systems.
When reading this document, also read the documents related to the
碌
PD17230, 17231, 17232, 17233, 17234,
17235, and 17236.
Detailed functions are described in the following user's manual. Read this manual when designing your system.
