4-BIT SINGLE-CHIP MICROCONTROLLERS

WITH DIGITAL TUNING SYSTEM HARDWARE

The µPD17933 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.
