µPD17P246
4-BIT SINGLE-CHIP MICROCONTROLLER
FOR SMALL GENERAL-PURPOSE INFRARED
REMOTE CONTROLLER
DESCRIPTION
The µPD17P246 is a model of the µPD17246 with a one-time PROM instead of an internal mask ROM.
Since the user can write programs to the µPD17P246, it is ideal for experimental production or small-scale
production of the µPD17240, 17241, 17242, 17243, 17244, 17245, or 17246 systems.
When reading this document, also read the documents related to the µPD17240, 17241, 17242, 17243, 17244,
17245, and 17246.
Detailed function descriptions are provided in the following user’s manual. Be sure to read them
before designing.
