DATA SHEET
MOS INTEGRATED CIRCUIT
µ PD17704, 17705, 17707, 17708, 17709
4-BIT SINGLE-CHIP MICROCONTROLLERS WITH DEDICATED
HARDWARE FOR DIGITAL TUNING SYSTEM
The µPD17704, 17705, 17707, 17708, and 17709 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, µPD17P709, which can be written only once and therefore is ideal for
program evaluation and small-scale production of a µPD17704, 17705, 17707, 17708, or 17709 system, is also
available.
