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...
