The monolithic integrated circuit said that the monolithic micro controller, it is not completes some logical function the chip, but integrates a computer system to a chip on. Summary speaking: A chip has become a computer. Its volume is small, the quality is light, and the price cheap, for the study, the application and the development has provided the convenient condition. At the same time, the study use monolithic integrated circuit is understands the computer principle and the structure best choice.
The monolithic integrated circuit interior also uses with the computer function similar module, for instance CPU, memory, parallel main line, but also has with the hard disk behave identically the memory component7 what is different is its these part performance is opposite our home-use computer weak many, but the price is also low, generally does not surpass 10 Yuan then Made some control electric appliance one kind with it is not the 'very complex work foot, We use now the completely automatic drum washer, the platoon petti-coat pipe: VCD and so on Inside the electrical appliances may see its form! It is mainly takes the control section the core part.
單片機又稱單片微控制器，它不是完成某一個邏輯功能的芯片，而是把一個計算機系統(tǒng)集成到一個芯片上。概括的講：一塊芯片就成了一臺計算機。它的體積小、質量輕、價格便宜、為學習、應用和開發(fā)提供了便利條件。同時，學習使用單片機是了解計算機原理與結構的最佳選擇。
單片機內部也用和電腦功能類似的模塊，比如CPU，內存，并行總線，還有和硬盤作用相同的存儲器件，不同的是它的這些部件性能都相對我們的家用電腦弱很多，不過價錢也是低的，一般不超過10元即可，用它來做一些控制電器一類不是很復雜的工作足矣了。我們現(xiàn)在用的全自動滾筒洗農機、排煙罩、VCD等等的家電里面都可以看到它的身影！它主要是作為控制部分的核心部件。
