PD17P228

4-BIT SINGLE-CHIP MICROCONTROLLER

FOR SMALL GENERAL-PURPOSE INFRARED

REMOTE CONTROLLER

DESCRIPTION

The

碌

PD17P228 is a model of the

碌

PD17228 with a one-time PROM instead of an internal mask ROM.

Since the user can write programs to the

碌

PD17P228, it is ideal for experimental production or small-scale

production of the

碌

PD17225, 17226, 17227 or 17228 systems.

When reading this document, also read the documents related to the

碌

PD17225, 17226, 17227 and 17228.

Detailed functions are described in the following user's manual. Read this manual when designing your system.
