UPD17933

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 memory (RAM) ) Instruction execution time 53.3 µ s (with 75-kHz crystal resonator) PLL frequency synthesizer Dual modulus prescaler (220 MHz MAX.), programmable divider, phase comparator, charge pump ORDERING INFORMATION Part Number Package 80-pin plastic TQFP (12 × 12 mm, 0.5 mm pitch) 80-pin plastic TQFP (12 × 12 mm, 0.5 mm pitch) µ PD17933GK- ××× -BE9 µ PD17934GK- ××× -BE9 Remark ××× indicates ROM code suffix.
