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 •...
