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.
