The
µ
PD17062 is a 4-bit CMOS microcontroller for digital tuning systems. The single-chip device
incorporates an image display controller enabling a range of different displays, together with a PLL frequency
synthesizer.
The CPU has six main functions: 4-bit parallel addition, logic operation, multiple bit test, carry-flag set/
reset, powerful interrupt, and a timer.
The device contains a user-programmable image display controller (IDC) for on-screen displays. The
different displays can be controlled with simple programs.
The device also has a serial interface function, many input/output (I/O) ports controlled by powerful I/O
instructions, and 6-bit pulse width modulation (PWM) output for a 4-bit A/D converter and D/A converter.
