1, flash IC is used to store data, I think it is more appropriate to call storage IC, also called BIOS in the PC world, similar IC and EEPROM, the function is basically the same, but the capacity is not the same;
2, logic IC is also logic IC, logic circuit, used for logical judgment, the common 74 series logic IC (74ACT....) , 74HC........ Etc.);
3, power IC is the power supply IC, used to supply power to the CPU, GPU, MCU and other core processors, common LDO, DC\/DC, PWM, Driver and so on
4, Amplifier IC, used to magnify, common: one used to operation amplification power; The other is audio IC;
5, protection IC used to protect the circuit, common ESD IC (electrostatic protection), OCP(overcurrent protection), OVP (overvoltage protection) and so on
6, the main control IC is the main chipsets, common GPU, CPU, MCU and so on
7, the industry's dedicated IC is used to achieve some specific functions, such as PC motherboard with NET(network card IC), CODEC (sound card IC), I\/0 (interface IC); Conversion ics for PC graphics cards (ics for VGA to DP, DP to HDMI, etc.)
An IC (Integrated Circuit) is an electronic component formed by integrating multiple discrete devices together. There are many kinds of ics, which can be divided into analog integrated circuits, digital integrated circuits, hybrid integrated circuits, microprocessors and so on according to different classification methods.
The analog integrated circuit is mainly used for analog signal processing, the digital integrated circuit is mainly used for digital signal processing, and the hybrid integrated circuit is a combination of the two. In addition, there are application-specific integrated circuits, such as sensor integrated circuits, power integrated circuits, etc. Common IC brands are TI, ADI, ST, NXP, Freescale, Infineon and so on.
