单片机是一种微控制器件,它是在一块硅片上集成了各种部件的微型计算机。这些部件包括中央处理器CPU、数据存储器RAM、程序存储器ROM、定时器/计数器、中断控制、系统时钟、系统总线、并行I/O、串行I/O等。MCS-51是指由美国INTEL公司生产的一系列单片机的总称,这一系列单片机包括了好些品种.如8031,8051,8751,8032,8052,8752等,其中8051是最早最的典型产品,该系列其它单片机都是在8051的基础上进行功能的增、减、改变而来的,所以人们习惯于用8051来称呼MCS51系列单片机,而8031是前些年在我国最流行的单片机,所以很多场合会看到8031的名
Microcontroller is a micro-control device, which is a micro-computer integrated with various components on a silicon. These components include the CPU, Data Memory RAM, Program Memory ROM, Timer / Counter, Interrupt Control, System Clock, System Bus, Parallel I / O, Serial I / O and more. MCS-51 refers to a series of microcontrollers produced by the United States INTEL company in general, this series of microcontrollers include a number of varieties, such as 8031,8051,8751,8032,8052,8752, etc., of which 8051 is the earliest and most typical products, the Series of other microcontrollers are based on the function of the 8051 increase, decrease, change, so people are accustomed to using the 8051 MCS51 series MCU, and 8031 is a few years ago in our country’s most popular microcontroller, so many occasions Will see the name of 8031
