What is a microcontroller? Application of Microcontrollers

Internationally, microprocessors are divided into three categories based on their application areas: general-purpose high-performance microprocessors,

embedded microprocessors, and microcontrollers. General purpose microprocessors pursue high performance and are mainly

used in workstations and high-performance personal computer systems. Embedded processors are mainly used to run specialized programs for specific fields,

equipped with lightweight operating systems. Its applications are extremely extensive, such as mobile phones VCD、

Set top boxes all use this type of processor. A microcontroller is a single-chip microcomputer that integrates the main components of a microcomputer

onto a single chip. Microcontrollers are mainly used for self-control equipment in fields such as automotive air conditioning and automatic machinery.

Microcontrollers are widely used in various industrial and civilian embedded systems due to their small size, low power consumption, and convenient use.

Microcomputer System Architecture

What is a microcontroller?
A microprocessor is a computer. All computers, whether they are personal desktop computers, large computers, or microcontrollers, have many similarities:

All computers have a CPU (Central Processing Unit) for executing programs. If you are sitting in front of a desktop computer reading this article, the CPU

of this computer is currently executing a program, which is a web browser used to display this webpage.

The CPU loads programs from a device. On your desktop computer, browser programs are loaded from the hard drive.
