Microcontrollers were produced with the development of electronic computers (computers). With the development of society and the improvement of needs, computers are constantly updated and developed. Since computers were born in response to numerical calculations, electronic computer technology has long been developed to meet the needs of a large number of high-speed numerical calculations. Until the 1970s, electronic computers were used in digital logic operations, reasoning, automatic control, etc. After revealing its extraordinary functions, computer technology development in various control fields began to put forward completely different requirements from traditional large-scale high-speed calculations. These requirements are: facing control objects, facing various sensor signals, facing human-computer interactive operation control, and being able to be easily embedded in industrial control application systems, etc.
In order to achieve the above requirements, in recent years, single-chip microcomputers (referred to as microcontrollers) have emerged. Microcontroller is also called “microcontroller” and “embedded microcontroller”. The term microcontroller originally originated from SCM. When the single-chip microcomputer was born, SCM was an accurate and popular term, and the word “single-chip microcomputer” accurately expressed this concept. As SCM continues to expand its control functions in terms of technology and architecture, the microcontroller can no longer accurately express its connotation as “single-chip microcomputer”. The international community gradually adopts “MCU” (Micro Controller Unit) instead, forming a recognized and ultimately unified term in the microcontroller industry. In China, the term “single-chip microcomputer” has become a common practice, so it continues to be used.
A single-chip computer integrates the basic components of an electronic computer, such as CPU (also known as central processing unit, mainly composed of arithmetic units and controllers), memory, bus, input and output interfaces, etc., on a silicon substrate using integrated circuit technology. . Because the single-chip computer is small in size (only about the size of a finger) and powerful (has the functions of a simple computer), it is widely used as a controller in electronic equipment. At present, it ranges from missiles, rockets, and cutting-edge national defense weapons to small Modern household appliances such as televisions and microwave ovens all use single-chip computers as controllers without exception. Therefore, from a control point of view, we often call it a single-chip microcontroller.

Abstract: SCM, as the electronic computer (computer) created in the development, along with social development and the improvement of demand, computers are also constantly updating and developmen t. The computer is the result of numerical calculations and should have, So long computer technolgy to meet all along the high-speed development of numerical computation, It was not until the 1 970s in the 20th century, computers in the digital logic operations, reasoning, Control areas shown remarkable feature, in various areas to control the development of computer technology with the t raditional high-speed calculation entirely different requirements. These requirements are: Facing the control object, in the face of various sensor signals, in the face of human-computer interaction operational control, can be easily embedded in industrial applications Medium. In order to achieve the above request, in recent years, single-chip microcomputer (SCM) emerged. SCM also called “micro-controller”, “Embedded Microcontrollers.” SCM is the first word from ” Single Chip Microcomputer” called SCM . SCM birth, SCM is an accurate description of the epide mic, “SCM” accurate expression of this – concept With SCM technology, architecture continuously expanded its control function, SCM is no “single-chip micro-computer” to accurately express its substance. formation of microcontroller industry recognized the ultimate reunification of the term. In the domestic as “SCM” has been customary, therefore, continue to be used. Single-chip computer to computer’s basic tasks, such as: CPU (also known as central processing u nits, mainly by the arithmetic unit, controller), memory, bus, the input and output interfaces, Integr ated IC technology used in a silicon-based chip. As the size of a small single-chip computer (only t he size fingers), strong function (with a simple computer function) that is widely used in electronic equipment used for the controller. Presently, the rocket missile defense sophisticated weapons, sm all microwave ovens to the TV and other modern household appliances, within which invariably u se the computer as a single-chip controller. Therefore, from the control point of view, we often call the single-chip microcontroller. Key Words: Embedded Microcontrollers, SCM, Integration.
