RTL8019AS在基于SCM的以太网通信节点中的应用

Application of RTL8019AS to ethernet communication nodebased on SCM

介绍了由89C52控制的RTL8019AS的设计方法.详细介绍了以太网通信节点的框架以及RTL8019AS和89C52组成之间的硬件连接和软件实现,并探讨了实际应用中遇到的问题.

Ethemet communication node can be realized by a single chip microcomputer（SCM） , RTL8019AS controlled by 80C52 can realize the functions ofSCM . In this paper, author not only introduce the framework of Ethemet communication node , hardware connection and soft realization of RTL8019AS and 89C52, but also mention and resolve the problems of application in practice in the end.
