4-BIT SINGLE-CHIP MICROCONTROLLERS

FOR SMALL GENERAL-PURPOSE INFRARED

REMOTE CONTROL TRANSMITTERS

DESCRIPTION

The µPD17240, 17241, 17242, 17243, 17244, 17245, 17246 (hereafter called the µPD17246 Subseries) are 4-

bit single-chip microcontrollers for small general-purpose infrared remote control transmitters.

This subseries employs 17K general-purpose register system architecture for the CPU, and can directly execute

operations between data memories instead of the conventional method of executing operations through an

accumulator. Moreover, all the instructions are 16-bit/1-word instructions, enabling efficient programming.

In addition, a one-time PROM model, the µPD17P246, to which data can be written only once, is also available.

This product is convenient either for evaluating the µPD17246 Subseries programs or for small-scale production of

application systems.

Detailed function descriptions are provided in the following user's manual. Be sure to read them before

designing.
