UPD17P236

DATA SHEET MOS INTEGRATED CIRCUIT µPD17P236 4-BIT SINGLE-CHIP MICROCONTROLLER FOR SMALL GENERAL-PURPOSE INFRARED REMOTE CONTROLLER The µPD17P236 is a model of the µPD17236 with a one-time PROM instead of an internal mask ROM. Since the user can write programs to the µPD17P236, it is ideal for experimental production or small-scale production of the µPD17230, 17231, 17232, 17233, 17234, 17235, or 17236 systems. When reading this document, also read the documents related to the µPD17230, 17231, 17232, 17233, 17234, 17235, and 17236. Detailed functions are described in the following user's manual. Read this manual when designing your system. µPD172×× Series User's Manual: U12795E FEATURES Pin compatible with µPD17230, 17231, 17232, 17233, 17234, 17235, and 17236 (except PROM programming function) Carrier generator circuit for infrared remote controller (REM output) 17K architecture: General-purpose register method Program memory (one-time PROM): 32 Kbytes (16,384 × 16) Data memory (RAM): 223 × 4 bits Low-voltage detection circuit Input/output of P1A0 pin, clock selection for carrier generation µPD17P236M1 Input/output of P1A0 pin Clock (RfX) selection for carrier generation Output RfX = fX/2 µPD17P236M2 Input µPD17P236M3 Output RfX = fX µPD17P236M4 Input Supply voltage: VDD = 2.2 to 3.6 V (fX = 4 MHz: high-speed mode, 4 µs) VDD = 3.0 to 3.6 V (fX = 8 MHz: high-speed mode, 2 µs) APPLICATIONS Preset remote controllers, toys, and portable systems The info...
