The W5500 chip is a Hardwired TCP/IP integrated Ethernet controller that makes it easier for embedded systems to connect to the Internet. W5500 allows customers to integrate Internet access into their applications using a single chip that includes a TCP/IP stack, a 10/100 Ethernet MAC, and a PHY.
TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE protocols are all supported by WIZnet’s Hardwired TCP/IP technology. For Ethernet packet processing, the W5500 includes a 32Kbyte internal memory buffer. If you’re using W5500, all you have to do is write a simple socket program to get the Ethernet application up and running. Using this method instead of any other Embedded Ethernet solution is faster and easier. Users can use up to eight different hardware sockets at the same time.
