Overview

DATA SHEET MOS INTEGRATED CIRCUIT µ PD17933, 17934 4-BIT SINGLE-CHIP MICROCONTROLLERS WITH DIGITAL TUNING SYSTEM HARDWARE The µ PD17933 and 17934 are 4-bit single-chip CMOS microcontrollers with hardware for digital tuning systems (DTSs).
These microcontrollers integrate a prescaler that operates at a voltage as low as 1.
05 V and up to 220 MHz, a PLL frequency synthesizer, an intermediate frequency (IF) counter, and an LCD controller/driver on a single chip.
Therefore, a high-performance digital tuning system for a portable set can be organized with a single chip.
FEATURES • Program memory (ROM) • Peripheral hardware General-purpose I/O ports, LCD controller/driver, serial interface, A/D converter, BEEP output, frequency counter • Interrupt External: 1 source Internal : 3 sources • Reset by RESET pin • Low power consumption • Supply voltage: V DD = 1.
05 to 1.
8 V µ PD17933 µ PD17934 448 × 4 bits • : 12K bytes (6144 × 16 bits) : 16K bytes (8192 × 16 bits) • General-purpose data me...
