1 / 32 page DATA SHEET © 2000 MOS INTEGRATED CIRCUIT µPD17P236 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 µPD17P236M2 µPD17P236M3 µPD17P236M4 Input/output of P1A0 pin Output Input Output Input Clock (RfX) selection for carrier generation RfX = fX/2 RfX = fX • 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 Document No. U14776EJ1V0DS00 (1st edition) Date Published June 2000 J CP(K) Printed in Japan 4-BIT SINGLE-CHIP MICROCONTROLLER FOR SMALL GENERAL-PURPOSE INFRARED REMOTE CONTROLLER The information in this document is subject to change without notice.
