The

µPD17068 is a 4-bit single-chip microcontroller for digital tuning systems. It contains an image display

controller (IDC) that supports many types of display, and a PLL synthesizer.

The CPU of the

µPD17068 is capable of 4-bit parallel addition, logical operations, bit tests, setting/resetting

of a carry flag, and supports a powerful interrupt function and timer function.

The image display controller for on-screen display is user-programmable, allowing a range of displays to

be programmed.

The peripheral hardware includes a full complement of I/O ports, controlled with powerful I/O instructions,

as well as a serial interface, a 6-bit A/D converter, and an 8-bit D/A converter (PWM output).
