What kinds of IC chips does the main control chip supplier talk about

Integrated circuit (IC) is a kind of integrated circuit which is formed by a large number of microelectronic components (transistors, resistors, capacitors, diodes, etc.) on a plastic base to make a chip. At present, almost all the chips we see can be called IC chips.

Integrated circuit is a kind of micro electronic device or component. Using a certain process, the transistor, diode, resistor, capacitor, inductor and other components needed in a circuit are interconnected and fabricated on a small or several small semiconductor chips or dielectric substrates, and then packaged in a shell to form a micro structure with the required circuit function; All the components have been integrated in the structure, which makes the electronic components a big step towards miniaturization, low power consumption and high reliability. It is represented by the letter "IC" in the circuit. The inventors of integrated circuits are Jack Kilby (silicon-based integrated circuits) and Robert Noyce (germanium based integrated circuits). Nowadays, most of the applications in semiconductor industry are silicon-based integrated circuits.

Now the main control chip industry will call the integrated circuit IC chip.

What are the types of IC chips

（1） Classification by functional structure

According to their functions and structures, integrated circuits can be divided into analog integrated circuits and digital integrated circuits.

Analog integrated circuits are used to generate, amplify and process all kinds of analog signals (signals whose amplitude changes with time). For example, the audio signal of the semiconductor radio, the tape signal of the tape recorder and player, etc.), and the digital integrated circuit is used to generate, amplify and process various digital signals (signals with discrete values in time and amplitude). For example, VCD, DVD playback audio signal and video signal).

The basic analog integrated circuits include operational amplifier, multiplier, integrated voltage regulator, timer, signal generator, etc. There are many kinds of digital integrated circuits. Small scale integrated circuits have many kinds of gate circuits, such as NAND gate, not gate, or gate, etc.; medium scale integrated circuits have data selector, encoder, decoder, trigger, counter, register, etc. Large scale or ultra large scale integrated circuits include PLD (programmable logic device) and ASIC (application specific integrated circuit).

From the perspective of PLD and ASIC, the difference between components, devices, circuits and systems is no longer very strict. Moreover, PLD device itself is only a hardware carrier, loading different programs can achieve different circuit functions. Therefore, modern devices are no longer pure hardware. Software devices and corresponding software electronics have been widely used in modern electronic design, and their status is becoming more and more important.

There are many kinds of circuit components, with the continuous improvement of electronic technology and process level, a large number of new devices continue to appear, the same device also has a variety of packaging forms, such as: chip components are everywhere in modern electronic products. For different environments, the same device has different industrial standards. Domestic components usually have three standards: civil standard, industrial standard and military standard. Different standards lead to different prices. The price of military standard devices may be ten times or even more than that of civil standards. Industry standard is between the two.

（2） Classified by manufacturing process

Integrated circuits can be divided into semiconductor integrated circuits and thin film integrated circuits according to the manufacturing process.

Thin film integrated circuits are classified into thick film integrated circuits and thin film integrated circuits.

（3） Classified according to the level of integration

According to scale, integrated circuits are divided into small scale integrated circuits (SSI), medium scale integrated circuits (MSI), large scale integrated circuits (LSI), very large scale integrated circuits (VLSI) and very large scale integrated circuits (ULSI).

（4） Classification according to conductive type

Integrated circuits can be divided into bipolar integrated circuits and unipolar integrated circuits.

Bipolar integrated circuits have complex manufacturing process and high power consumption. The representative integrated circuits are TTL, ECL, HTL, lst-tl, sttl and so on. Unipolar IC is easy to be made into large-scale integrated circuit because of its simple manufacturing process and low power consumption. The representative IC includes CMOS, NMOS, PMOS and so on.

（5） Classification by use

Integrated circuits can be divided into TV integrated circuits according to their uses. Integrated circuits for audio, video disc player, video recorder, computer (microcomputer), electronic organ, communication, camera, remote control, language, alarm and other special integrated circuits.

The integrated circuits for TV include line and field scan integrated circuits, middle amplifier integrated circuits, sound integrated circuits, color decoding integrated circuits, AV / TV conversion integrated circuits, switching power supply integrated circuits, remote control integrated circuits, Liyin decoding integrated circuits, picture in picture processing integrated circuits, microprocessor (CPU) integrated circuits, memory integrated circuits, etc.

Audio IC includes AM / FM high and medium frequency circuit, stereo decoding circuit, audio preamplifier circuit, audio operational amplifier IC, audio power amplifier IC, surround sound processing IC, level driving IC, electronic volume control IC, delay reverberation IC, electronic switch IC, etc.

The integrated circuits for DVD player include system control integrated circuit, video coding integrated circuit, MPEG decoding integrated circuit, audio signal processing integrated circuit, audio effect integrated circuit, RF signal processing integrated circuit, digital signal processing integrated circuit, servo integrated circuit, electric drive integrated circuit, etc.
