DATA SHEET MOS INTEGRATED CIRCUIT µPD17230,17231,17232,17233,17234,17235,17236 4-BIT SINGLE-CHIP MICROCONTROLLER FOR SMALL GENERAL-PURPOSE INFRARED REMOTE CONTROL TRANSMITTER DESCRIPTION µPD17230, 17231, 17232, 17233, 17234, 17235, 17236 (hereafter called µPD17236 subseries) are 4-bit singlechip 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.
