W5100 is a multi-purpose single internet interface chip, integrated 10/100 ethernet controller inside,and applied to embedded system which is high integration, high stability, high performance and low cost. It can be connected to Internet without operating system and compatible with IEEE802.3 10BASE-T and 802.3u 100BASE-TX. It contains TCP/IP protocol stack that is full-hardware and verified by market for years, ethernet medium transport layer and physical layer. You don’t need to consider the control of ethernet, and just need simple program of ports.
