DATA SHEET
MOS INTEGRATED CIRCUIT
PD17P236
4-BIT SINGLE-CHIP MICROCONTROLLER
FOR SMALL GENERAL-PURPOSE INFRARED
REMOTE CONTROLLER
The
PD17P236 is a model of the
PD17236 with a one-time PROM instead of an internal mask ROM.
Since the user can write programs to the
PD17P236, it is ideal for experimental production or small-scale
production of the
PD17230, 17231, 17232, 17233, 17234, 17235, or 17236 systems.
When reading this document, also read the documents related to the
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.
