摘要
本文主要介绍了一种新颖的MCS-51单片机大容量数据存储器(超过64K)的扩展方法,并在Proteus7.7下仿真通过,验证了该方法的可行性.该方法新颖之处有两点:一是不占用任何一个I/O端口;二是扩展用器件常见、简单.
The paper introduces a new method to extend MCU, and the method is tested by ProteusT.7 simulation. The port, and the extended chips are simple and common. mass data .memory （to exceed 64K）based on MCS-51 method has two advantages：it doesn＇t occupy any I/O
