摘要

随着电子通信技术的发展，电子产品已被广泛的用于社会的各个领域，成为推动社会发展的技术动力一种。而在电子产品应用中，单片机的作用十分突出，单片机已经发展成为电子技术的核心，主导着电子产品的开发和电子技术市场的进一步的开拓。电子产业已成为社会电子信息化进程中的一个战略性产业。在电子技术的应用中，单片机的开发技术尤其是应用型电子产品的开发技术成了重中之重。不断开发适应用户需求、市场需要的新型电子产品。随着社会的发展，单片机也在不断的更新换代。AT89C51是一个低电压，高性能CMOS 8位单片机，利用AT89C51单片机控制发光二极管点亮来表现一按键多种功能。文章对AT89C51单片机芯片，晶体振荡器，涉及到的各元器件以及按键控制模型做了详细的介绍。

Abstract

With the development of electronic communication technology, electronic products have been widely used in various fields of society, becoming the driving force for social development of a technology. Electronic products in applications, a very prominent role of single-chip, single-chip electronic technology has developed into the core dominate the electronic product development and electronic technology to open up the market further. Electronics industry has become a society of electronic information in the process of a strategic industry. In electronic technology applications, single-chip technology, especially the development of application-oriented product development of electronic technology has become a top priority. Adapt to user needs to continuously develop, the market required a new type of electronic products. With the development of society, single-chip microcomputer are also constantly upgrading. AT89C51 is a low-voltage, high-performance CMOS 8-bit single chip, using AT89C51 single-chip microcomputer to control the performance of LED lighting to a variety of functions one button. Article on the AT89C51 single-chip microcomputer chip, crystal oscillator, involving the various components as well as the button control model to do a detailed introduction.
