UPD17062

DATA SHEET MOS INTEGRATED CIRCUIT µPD17062 4-BIT SINGLE-CHIP MICROCONTROLLER CONTAINING PLL FREQUENCY SYNTHESIZER AND IMAGE DISPLAY CONTROLLER The µPD17062 is a 4-bit CMOS microcontroller for digital tuning systems. synthesizer. The single-chip device incorporates an image display controller enabling a range of different displays, together with a PLL frequency 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. FEATURES 4-bit microcontroller for digital tuning system Internal PLL frequency synthesizer: With prescaler Internal image display controller (IDC) (user-programmable) Number of characters in display: Up to 99 on a single screen Display configuration: 14 rows × 19 columns Number of character types: 120 Character format: 10 × 15 dots (rimming possible) Number of colors: 8 Character size: Four sizes in each of the horizontal and vertical dimensions Internal 1H circuit for preventing vertical deflection Internal 8-bit serial interface (One system with two channels: three-wire or two-wire) Interrupt...
