DATA SHEET  
MOS INTEGRATED CIRCUIT  
µPD17240,17241,17242,17243,17244,17245,17246  
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.
