UPD17933GK

The UPD17933GK is a 4-bit single-chip CMOS microcontroller with hardware for digital tuning systems (DTS).The microcontroller 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.
