PD17P218
4-BIT SINGLE-CHIP MICROCONTROLLER
FOR INFRARED REMOTE CONTROLLER
DESCRIPTION
The
碌
PD17P218 is a model of the
碌
PD17218 with a one-time PROM instead of an internal mask ROM.
Since the user can write programs to the
碌
PD17P218, it is ideal for experimental production or small-scale
production of the
碌
PD17215, 17216, 17217 or 17218 systems.
When reading this document, also read the documents related to the
碌
PD17215, 17216, 17217 and 17218.
Detailed functions are described in the following user鈥檚 manual. Read this manual when designing your
system.
