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. µPD172×× Subseries User's Manual: IEU-1317 FEATURES Infrared remote controller carrier generator circuit (REM output) 17K architecture: General-purpose register system Program memory (ROM), Data memory (RAM) µPD17215 Program memory (ROM) 4 K bytes (2048 × 16) Data memory (RAM) µPD17216 8 K bytes (4096 × 16) µPD17217 12 K bytes (6144 × 16) µPD17218 16 K bytes (8192 × 16) 111 × 4 bits 223 × 4 bits 8-bit timer : 1 channel Basic internal timer / Watchdog timer: 1 channel ...
