UPD17933 Product details

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.

FEATURES
• Program memory (ROM)
    µPD17933 : 12K bytes (6144 × 16 bits)
    µPD17934 : 16K bytes (8192 × 16 bits)
• General-purpose data memory (RAM) )
    448 × 4 bits
• Instruction execution time
    53.3 µs (with 75-kHz crystal resonator)
• PLL frequency synthesizer
    Dual modulus prescaler (220 MHz MAX.),
    programmable divider, phase comparator,
    charge pump
• 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: VDD = 1.05 to 1.8 V
