Overview

PRELIMINARY DATA SHEET MOS INTEGRATED CIRCUIT µ PD17717, 17718, 17719 4-BIT SINGLE-CHIP MICROCONTROLLERS WITH DEDICATED HARDWARE FOR DIGITAL TUNING SYSTEM The µ PD17717, 17718, and 17719 are 4-bit single-chip CMOS microcontrollers containing hardware for digital tuning systems.
Provided with a wealth of hardware, these microcontrollers are available in many variations of ROM and RAM capacities to support various applications.
Therefore, a high-performance, multi-function digital tuning system can be configured with only one chip.
In addition, a one-time PROM model, µ PD17P719, which can be written only once and therefore is ideal for program evaluation and small-scale production of a µ PD17717, 17718, or 17719 system, is also available.
FEATURES • Program memory (ROM) • Abundant peripheral hardware units General-purpose I/O ports, serial interfaces, A/D converter, D/A converter (PWM output), BEEP output, frequency counter • Many interrupts External: 6 sources Internal : 6 sources • Power-ON reset, CE reset, and power failure detection circuit • Supply voltage: V DD = 5 V ± 10 % µ PD17717 : 24K bytes (12288 × 16 bits) µ PD17718, 17719: 32K bytes (16384 × 16 bits) • General-purpose data memory (RAM) µ PD17717, 17718: 1120 × 4 bits µ PD17719 : 1776 × 4 bits • Instruction execution time 1.
78 µ s (with f X = 4.
5-MHz crystal oscillator) • PLL frequency synthesizer Dual modulus prescaler (130 MHz MAX.
