Difference between microprocesor and microcontroller

Today in this article I will discuss the difference between a microprocessor and a microcontroller.

What is a Microprocessor?

A microprocessor is the main functional component of a computer. It is an electronic circuit on a small chip called an integrated chip (IC) which consists of various electronic components such as transistors, resistors, diodes, etc that works together to perform an operation.

A microprocessor processes all the user or system inputs and gives the required output to an output device. It also controls all peripheral devices connected to a computer system.

Examples of microprocessors are Intel 4004, 8085, Intel i3, i7, AMD Ryzen 5, etc.

What is a Microcontroller?

A microcontroller or microcontroller unit (MCU) is an electronic chip optimized to perform a specific task. It is consist of a processor, memory, and programmable I/O.

A microcontroller is designed and used in automatically controlled electronic devices to perform a specific task repeatedly. It processes user input or input provided by sensors and outputs a certain action based on the given input.

Examples of microcontrollers are Intel 8031/8051, PIC1x, ATmega328, ATmega8, etc.
