摘　　要：I^2C串行总线是Philips公司为有效实现电子器件之间的控制而开发的一种简单的双向两线总线。现在,I^2C总线已经成为国际标准,应用涉及家电、通信、控制等众多领域,特别是在ARM嵌入式系统开发中得到广泛应用。TD-SCDMA(时分同步码分多址)技术是中国具有自主知识产权的第三代移动通信系统技术,打破了国外垄断通信市场的局面,它作为民族产业,在最近几年得到了突飞猛进的发展。文中介绍基于OMAP(开放式多媒体应用平台)的I^2C串行接口在TD-SCDMA手机的RTC(实时时钟)控制功能。I^2C serial bus is one kind of simple bi-directional two line bus which is developed for effective control between the electronic devices by the Philips corporation. Now I^2C bus has become an international standard, and it is used in household electrical appliances, communications, controlling, and many other fields, especially in the ARM embedded system development. TD-SCDMA technology has independent intellectual property rights in China, and it is a third-generation mobile communication system technology, which has broken the monopoly of market by foreign communications companies. As a branch of national industry, it developed rapidly in recent years. This paper introduces the I^2C serial interface based on the OMAP platform and the RTC（real time clock）control functions in TD-SCDMA mobile phones.
