Difference between Microprocessor and Microcontroller

Arduino Jan 25, 2022

Hello People. This post explains the difference between microprocessor and microcontroller. Choosing between a microprocessor and a microcontroller is an important step.

What is a Microcontroller?

A Microcontroller is a single Integrated Circuit.  It is used for a specific application and designed to implement certain tasks. Example products are devices that must be automatically controlled in certain situations like appliances, power tools, automobile engine control systems, and computers.

Basically a microcontroller gathers input, processes this information, and outputs a certain action based on the information gathered. Microcontrollers usually operate at lower speeds, around the 1MHz to 200 MHz range. They are designed to consume less power because they are embedded inside other devices that can have greater power consumptions in other areas.

What is a Microprocessor?

A Microprocessor is an electronic component. It is used by a computer to do its work. It is a central processing unit on a single integrated circuit chip containing millions of very small components including transistors, resistors, and diodes that work together. Microprocessors help to do everything from controlling elevators to searching the Web. Everything a computer does is described by instructions of computer programs, and microprocessors carry out these instructions many millions of times a second.

Difference Between Microprocessor and Microcontroller

The main difference between microprocessor and microcontroller is that the IC of a Microprocessor just has a particular CPU inside it whereas the Microcontroller IC also has ROM, RAM, and other instruments attached to it. Some common examples of the microprocessor are AMD Athlon, Intel Core i7, Broadcom BCM2711, Raspberry Pi, etc. Some popular examples of microcontrollers are STM32, Arduino UNO, ATmega328, PIC16F877A, etc.

Choosing between Microprocessor and Microcontroller can be crucial. The need to have the best balance between performance, price, and power consumption has different key factors. At first you should focus on the model . However, when the microprocessor (MPU) or the microcontroller (MCU), becomes the foundation of the system approach, your final decision may become important. As a result, knowing the difference between microprocessor and microcontroller becomes a considerable subject at this step.
