摘　　要：单片机技术的应用是现代诸多智能终端电子产品的主要技术之一,与其相关的课程是大部分高校工科类学生必修课程之一。为辅助学生对单片机存储单元数据的烧写、读取和擦除的工作原理及过程的理解,采用CD4520同步加计数器、74HC154 4线-16线译码器和开关矩阵电路等器件,研究设计基于Proteus的实验电路模型。通过仿真实验,展现了数据在存储器中的烧写、读取和擦除的工作原理及过程。The application of single chip microcomputer(SCM) is one of the main technologies in smart terminal electronics of modern society, and relevant courses present compulsory ones of university students in engineering. In order to improve students’ understanding of the operating principle and the process of programming, reading and erasing the data in the memory units of a SCM,this paper adopts CD4520(synchronous counter), 74HC154(a 4-line to 16-line decoder), and a switch matrix circuit to design a model of experimental circuit based on Proteus. The simulation experiment demonstrates the operating principle and the process of programming, reading and erasing the the data in the memory units of a SCM.
