基于CP2200芯片的以太网控制器的设计

Design of Ethernet Controller Based on CP2200 Chip

针对当前以太网控制器体积大、接口电路复杂和实现难度大等问题,文章采用体积小、功能强大的CP2200作为以太网的通信接口控制芯片;以温度/压力监测系统为背景平台,介绍CP2200的功能和以其为核心的以太网控制器的硬件和软件设计;经实验测试表明,在温度/压力监测系统使用CP2200设计的以太网控制器后,能很好地实现网络远程登录对温度和压力实时监测的功能;因此该以太网控制器有着很高的实用价值。

In view of the existing problem of the Ethernet controller, such as the big size, the complex interface circuit and the difficult realization, this paper uses a small, powerful CP2200 as the communication interface chip of a Ethernet controller. At the background and platform of the temperature and pressure monitoring system, it introduces the functions of CP2200 and the hardware and software design based on CP2200. The experiment shows that after using this Ethemet controller in the system, a remote login on network comes true and it can monitor temperature and pressure in time. So this Ethemet controller has high worthy of application.
