一、概述在整个计算机产品应用“树”中,其庞大的根系尖端,就是单片微型机化的产品。所渭单片微型机(简称单片机),就是在一片晶体芯片上(自然是一个IC封装之中)将一个典型的数字计算机系统所应有的4个基本组成部份:中央处理器(CPU);程序存储器(ROM);数据存储器(RAM);输入/输出接口(I/O接口)做在一起。例如,Intel公 First, an overview In the entire computer product application “tree”, its huge root tip, that is, single-chip microcomputer products. Wei Wei single chip microcomputer (referred to as single chip microcomputer), is in a crystal chip (which is naturally a IC package) will be a typical digital computer system should have four basic components: the central processing unit (CPU) ; Program memory (ROM); data memory (RAM); input / output interface (I / O interface) together. For example, Intel public
