## Article

Refer to the chip introduction in the data manual ：“W5500 It's all hardware TCP/IP Embedded Ethernet Controller , It provides a more simple Internet connection scheme for embedded system .W5500 Integrated TCP/IP Protocol stack ,10/100M Ethernet data link layer （MAC） And physical layer （PHY）, So that users can use a single chip to expand network connectivity in their applications .” A lot of people have come into contact with ENC28J60 This network card chip , By comparison W5500 Have your own TCP/IP Protocol stack , and ENC28J60 The chip is just PHY and MAC layer , It needs to be ported LwIP、uIP Wait for the network protocol stack to connect to the network ,W5500 Self contained TCP/IP The protocol stack makes the embedded processor do not have to deal with complicated network protocol stack things , Focus on Application Development . however W5500 There are not many types of protocols supported , Support hardware TCP/IP agreement ：TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE, Application layer protocols need to be implemented by themselves , It doesn't matter , The implementation of the application layer protocol is better than the implementation of the transport layer 、 The network layer is much simpler , But there are too many kinds of protocols in the application layer .
