DATA SHEET MOS INTEGRATED CIRCUIT µPD17215, 17216, 17217, 17218 4-BIT SINGLE-CHIP MICROCONTROLLER FOR SMALL GENERAL-PURPOSE INFRARED REMOTE CONTROL TRANSMITTER DESCRIPTION µPD17215, 17216, 17217, 17218 (hereafter called µPD17215 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.
