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.
