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.
