The W5500 is a full-featured TCP/IP embedded Ethernet controller that provides an easier Internet connection solution for embedded systems. The hardware logic gates are used to implement the transport layer and network layer of the TCP/IP protocol stack (eg TCP). , UDP, ICMP, IPv4, ARP, IGMP, PPPoE and other protocols), and integrated data link layer, physical layer, and 32K bytes of on-chip RAM as data transceiving buffer. The host computer main control chip only needs to undertake the processing task of the TCP/IP application layer control information. Thereby, the workload of the host computer for data copying, protocol processing and interrupt processing is greatly saved, and the system utilization and reliability are improved.
