A microprocessor is a CPU that features multiple integrated circuits containing logic, control, and arithmetic circuitry needed for a typical CPU to function correctly.
The microprocessor was invented by a team of silicon engineers and logic architects: Marcian (Ted) Hoff, Masatoshi Shima, Federico Faggin, and Stanley Mazor.
The microcontroller puts the central processing unit and other peripherals onto the same chip to function. The microcontroller features a single-chip housing a more powerful CPU; this chip also connects to other external peripherals.
