DATA SHEET  
MOS INTEGRATED CIRCUIT  
µPD17225, 17226, 17227, 17228  
4-BIT SINGLE-CHIP MICROCONTROLLER  
FOR SMALL GENERAL-PURPOSE INFRARED  
REMOTE CONTROL TRANSMITTER  
DESCRIPTION  
µPD17225, 17226, 17227, 17228 (hereafter called µPD17225 subseries) are 4-bit single-chip microcontrollers for  
small general-purpose infrared remote control transmitters.  
It employs a 17K architecture of general-purpose register type devices for the CPU, and can directly execute  
operations between memories instead of the conventional method of executing operations through the accumulator.  
Moreover, all the instructions are 16-bit 1-word instructions which can be programmed efficiently.  
In addition, a one-time PROM model, µPD17P218, to which data can be written only once, is also available. It is  
convenient either for evaluating the µPD17225 subseries programs or small-scale production of application systems.  
Detailed functions are described in the following manual. Be sure to read this manual when designing your  
system.
