ON-CHIP IMAGE DISPLAY CONTROLLER 4-BIT SINGLE-CHIP MICROCONTROLLER FOR VOLTAGE SYNTHESIZER

μPD17053 includes the image display controller (IDC) which is capable of various displays and the 4-bit single-chip microcontroller for the voltage synthesizer in which the 14-bit D/A converter for voltage synthesizer is incorporated.
The CPU has such functions as 4-bit parallel addition, logical operation, multiple-bit testing, carry-flag set/reset, powerful interrupt and timer functions.
Incorporated with a user programmable image dipslay controller for on-screen dipslay, the CPU can control various displays with a simple program.
The appearance, which is 64-pin plastic sealing DIP, has the various I/O ports and serial ingerface functions controled by powerful input/output commands as well as 4-bit A/D converter and D/A converter (PWM) outputs.
