UPD17P218

DATA SHEET MOS INTEGRATED CIRCUIT µPD17P218 4-BIT SINGLE-CHIP MICROCONTROLLER FOR INFRARED REMOTE CONTROLLER DESCRIPTION The µPD17P218 is a model of the µPD17218 with a one-time PROM instead of an internal mask ROM. Since the user can write programs to the µPD17P218, it is ideal for experimental production or small-scale production of the µPD17215, 17216, 17217 or 17218 systems. When reading this document, also read the documents related to the µPD17215, 17216, 17217 and 17218. Detailed functions are described in the following user’s manual. Read this manual when designing your system. 5 µPD172×× Series User’s Manual: IEU-1317 FEATURES Pin compatible with µPD17215, 17216, 17217 and 17218 (except PROM programming function) Carrier generator circuit for infrared remote controller (REM output) 17K architecture: General-purpose register method Program memory (one-time PROM): 16K bytes (8192 × 16) Data memory (RAM): 223 × 4 bits Pull-up resistor can be connected to RESET pin Note.
