The W5500 is one of WIZnet's high-performance Ethernet interface chip series, with integrated hardware/TCP/IP stack + MAC+PHY. The full hardware protocol stack technology uses hardware logic gate circuit to realize complex TCP/IP protocol cluster. Its application has obvious advantages such as simple and fast, high reliability and good security. The internal integrated MAC and PHY technology makes the single chip access Ethernet solution. The hardware design is simpler and more efficient.
