UPD17062 Datasheet 4-bit Single-chip Microcontroller

Manufacturer: NEC (now Renesas Electronics)

Overview: 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.
