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.
