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. It is
convenient either for evaluating the µPD17215 subseries programs or small-scale production of application systems.
Detailed functions are described in the follwing manual. Be sure to read this manual when designing your
system.
