What is the difference between MCU, single -chip machine, chip?

Friends working in the electronic industry often hear the words of chips, single -chip machines, and MCUs, but they may not understand the meaning of the three. Many people will ask what is the difference between MCU, single -chip machine, and chip. Today this article will answer the connection and differences of the three in detail.

First of all, to explain the difference between the MCU and the single -chip microcomputer. The MCU is abbreviated by the English word MicroController Unit, and the Chinese meaning is a single -chip microcomputer, which is called the single -chip microcomputer.

Therefore, the MCU is actually a single -chip microcomputer, but the sayings of various occasions are different. The essence is the same, which is equivalent to the different titles of the same person. Therefore, the following mainly introduces the difference between the single chip machine and the chip.

1. Different body difference
1. Single -chip microcomputer: It is an integrated circuit chip. It is a small and large -scale integrated circuit technology to integrate the central processor CPU, random memory RAM, and only read memory ROM. Complete miniature computer system.

2. Chip: Chip is a collective name for semiconductor component products. It has a wide range. The method of miniaturizing circuits and often manufacture a semiconductor element on the surface of semiconductor wafers.

Second, different advantages
Single -chip machine: Single -chip machine has high integration and strong reliability. Even if the single -chip machine works for a long time, it is not easy to fail.

Chip: The chip is the core of a microprocessor or multi -core processor, which can control everything from the computer to the mobile phone to the microwave oven.

3. Features
Single -chip microcomputer: The volume of the single -chip microcomputer is relatively small. The internal chip is used as a computer system. Its structure is simple, but the function is complete. It is very convenient to use. It can be modularized.

Chip: The scale production capacity of integrated circuit, reliability, and the modular method of circuit design ensure the rapid adoption of standardized integrated circuits instead of design and use of discrete transistors.

In summary, a single -chip microcomputer is also called a single -chip micro computer. Although it looks like a chip, it already has basic processors and memory. It can be written into some simple control programs. Essence Most of the chips cannot be written into programming. They are already set up when they leave the factory, and their functions are relatively single.
