基于W5100芯片的网络通信电路设计

摘要

W5100 is a network interface chip with high integration density. 10/100M ethernet controller is integrated in this chip. By a simple interface operation, W5100 chip can realize internet connection without operating system. It is mainly used in the em-bedded system of lower cost and high stability. Internal structure, pins distribution, interface mode and hardware circuit design of W5100 chip are introduced.%W5100芯片是一种高集成度的网络接口芯片，内部集成有10/100M以太网控制器，经过简单的接口操作，可以实现没有操作系统的internet连接，主要应用于成本较低、稳定性较高的嵌入式系统中。本文介绍了W5100的内部构成、引脚分布、接口方式及硬件电路设计。
