IC, the abbreviation of integratedcircuit, that is, integratedcircuit), is a general term for semiconductor component products. More broadly speaking, it also involves all electronic components, such as resistors, capacitors, circuit plates \/PCB plates, and many other related products. MCU(MicroControlUnit) Chinese name is called micro control unit, also known as single chip microcomputer (SingleChipMicrocomputer) or MCU, refers to the emergence and development of large-scale integrated circuits, The computer's CPU, RAM, ROM, timing counter and a variety of I\/O interfaces are integrated on a chip to form a chip-level computer. The single chip microcomputer (MUC) is an IC(integrated circuit) single chip. The electronic module is usually composed of a variety of ics with a certain function of the device or integrated circuit board.
