Chip technology is the most important in the field of science and technology. Chip is just needed for any country. Chips are widely used in computers, mobile phones, home appliances, automobiles, and other electronic products and systems. Chips emphasize the integration, production and packaging of circuits. Chips are of great significance for scientific and technological innovation. Chips are everywhere and change our life all the time. No matter what equipment is inseparable from chips. Chips are mainly divided into memory chips, power chips and logic chips according to their functions, but the manufacturing process of chips is very complex, and the chip production line involves about thousands of processes. What are the working principles and functions of the chip?

Chip is a kind of integrated circuit, which is composed of a large number of transistors, also known as integrated circuit. It can be understood as miniaturizing the circuit. Different chips have different integration scales, up to hundreds of millions; As small as dozens or hundreds of transistors. In fact, a chip is a highly integrated circuit board, which can also be called IC. For example, the CPU of a computer is also a chip. Different IC systems have different functions. For example, video encoding and decoding IC is specially used to process video data, and audio encoding / decoding IC is used to process sound. If the CPU is compared to the heart of the whole computer system, the chipset on the motherboard is the trunk of the whole body. For the motherboard, the chipset almost determines the function of the motherboard, and then affects the performance of the whole computer system. The chipset is the soul of the motherboard.

In fact, the role of the chip can be very extensive. It can not only be installed in the computers we usually use, but its role is actually very broad. In our ordinary life, there are chips everywhere, which exist in our mobile phones; In the TV; In the air conditioner; In the water heater; The little thing remote control is inseparable from it. Chips can be seen everywhere in our life. Without chips, we can say that there is no technology. It is the soul of an electrical appliance.

The main function of the chip is to complete the operation and processing tasks. The integrated circuit is to package a circuit into a small component.

The working principle of the chip is to make the circuit on the surface of the semiconductor chip for operation and processing.

Integrated circuits have two main advantages over discrete transistors: cost and performance. The low cost is because the chip prints all components as a unit through photolithography technology, rather than making only one transistor at a time. The high performance is due to the fast switching of components, which consumes less energy because the components are small and close to each other. In 2006, the chip area ranged from a few square millimeters to 350 mm2, reaching one million transistors per mm2.

Digital integrated circuits can contain anything, from thousands to millions of logic gates, flip flops, multitasking and other circuits on a few square millimeters. The small size of these circuits makes them have higher speed, lower power consumption and lower manufacturing cost compared with board level integration. These digital ICs, represented by microprocessors, digital signal processors and microcontrollers, use binary to process 1 and 0 signals.

In fact, there is only one way to connect the chip with the outside world, that is, the pin. The so-called pin is just two functions: one is input, which is used to monitor the external state. Whether it is external interrupt or serial port reception, it is a special state of input; One is output, which is used to control the outside world. Whether it is serial output, PWM is just a special form of output.
