What is a single chip, for example, common single chip microcomputer manufacturers and common single

1. The microcontroller is a typical embedded microcontroller (microcontrollerunit), which is composed of combinators, controllers, memory, input and output devices, etc., which is equivalent to a micro computer.

2. Compared with the general-purpose microprocessor used in personal computers, it emphasizes more self-improvement (without external hardware) and cost saving. Its biggest advantage is that it is small in size and can be placed inside the instrument, but the storage capacity is small, the input and output interface is simple, and the function is low. Due to its rapid development, the definition of the old microcontroller can no longer be satisfied, so it is called a wider range of microcontrollers in many applications; From the 80s of the last century, from the 4-bit and 8-bit single-chip microcomputers at that time, it has developed to the current 32-bit 300m high-speed single-chip microcomputer.

3. Due to the wide application of single-chip microcomputer in the field of industrial control, single-chip microcomputer is developed from a special processor chip with only CPU. The original design idea was to integrate a large number of peripherals and CPUs into a single chip, making computer systems smaller and easier to integrate into complex and bulky control devices.

In daily life, single-chip microcomputers can often be seen, but even if the group is like this, there are many people who don't know what a single-chip microcomputer is? To put it simply, a single-chip microcomputer is a chip, but this chip is a highly integrated circuit chip, which is a very small computer system, I think there should be many people curious about what a single-chip microcomputer is at this time? Next, I will give you a detailed introduction to what a monolithic dry machine is.

MCU definition.

Single-chip microcomputer, also known as single-chip microcontroller, English name is microcontrollers, it is a special chip, and the circuit inside the chip is very dense, in addition, it is these circuits that bring together the best processor CPU, I O port, memory ROM and other functions together, single-chip microcomputer and computer are relatively speaking, most of its functions are still the same, except that single-chip microcomputer does not have I o equipment, but the volume of single-chip microcomputer and ** is smaller than the computer, And the microcontroller is more convenient to carry.

Since the 80s of the 20th century, the single-chip microcomputer has maintained rapid development, in terms of its development process, from the initial 4-bit single-chip microcomputer, 8-bit single-chip microcomputer, to today's 300m single-chip microcomputer.

Application classification of single-chip microcomputer.

Generally speaking, there are three types of application classifications of single-chip microcomputers, namely general-purpose type, control type, and bus type.

The basic structure of a single-chip microcomputer.

The basic structure of the microcontroller is very simple, consisting of three parts, namely combinator, main register, and controller. There are five main registers, namely accumulator A, data register DR, instruction register IR and instruction decoder ID, program counter PC, and address register AR.

The application range of single-chip microcomputer.

The application range of single-chip microcomputer has developed from the initial only use of industrial aspects, to the current multi-faceted and wide field, basically every field and every industry will be used to single-chip microcomputer, especially in industries with high technology content, such as: automobiles, network communications, household appliances, intelligent machines, etc.

Characteristics of the microcontroller.

There are many characteristics of single-chip microcomputer, so I will talk about it specifically.

1. The size of the single-chip microcomputer is very small and it is very convenient to carry.

2. The reliability of the single-chip microcomputer is very strong, and it can work continuously for a day without any problem.

3. The power consumption and energy consumption of single-chip microcomputer are very small.

4. The operation of single-chip microcomputer is very convenient.

5. The adaptability of single-chip microcomputer is very strong.

6. The structure of the single-chip microcomputer is very simple, and it is very convenient to use.

7. The processing system of single-chip microcomputer is still very powerful.

Single chip microcomputer (single chip microcomputer) microcomputer is referred to as single-chip microcomputer, is a typical embedded microcontroller (microcontroller unit), single-chip microcomputer chip commonly used abbreviation of English letters MCU means single-chip microcomputer, single-chip microcomputer is also known as single-chip microcontroller, it is not a chip that completes a certain logic function, but integrates a computer system into a chip. The microcontroller is composed of combinators, controllers, memory, and input and output devices, which is equivalent to a miniature computer (the smallest system), and compared with the computer, the microcontroller lacks peripheral devices. In a nutshell:

A chip becomes a computer. It is small in size, light in weight and cheap, which provides convenient conditions for learning, application and development. At the same time, learning to use a microcontroller is the best choice to understand the principles and structure of computers.

It was first used in the field of industrial control.
