PRELIMINARY DATA SHEET
MOS INTEGRATED CIRCUIT
µPD17717, 17718, 17719
4-BIT SINGLE-CHIP MICROCONTROLLERS WITH DEDICATED
HARDWARE FOR DIGITAL TUNING SYSTEM
The µPD17717, 17718, and 17719 are 4-bit single-chip CMOS microcontrollers containing hardware for
digital tuning systems.
Provided with a wealth of hardware, these microcontrollers are available in many variations of ROM and RAM
capacities to support various applications.
Therefore, a high-performance, multi-function digital tuning system can be configured with only one chip.
In addition, a one-time PROM model, µPD17P719, which can be written only once and therefore is ideal for
program evaluation and small-scale production of a µPD17717, 17718, or 17719 system, is also available.
FEATURES
• Program memory (ROM)
µPD17717
: 24K bytes (12288 × 16 bits)
µPD17718, 17719: 32K bytes (16384 × 16 bits)
• General-purpose data memory (RAM)
µPD17717, 17718: 1120 × 4 bits
µPD17719
: 1776 × 4 bits
• Instruction execution time
1.78 µs (with fX = 4.5-MHz crystal oscillator)
• PLL frequency synthesizer
Dual modulus prescaler (130 MHz MAX.),
programmable divider, phase comparator, charge
pump
• Abundant peripheral hardware units
General-purpose I/O ports, serial interfaces, A/D
converter, D/A converter (PWM output), BEEP
output, frequency counter
• Many interrupts
External: 6 sources
Internal : 6 sources
• Power-ON reset, CE reset, and power failure
detection circuit
• Supply voltage: VDD = 5 V ± 10 %
