W5300
W5300 is a hardwired TCP/IP stack internet controller chip with WIZnet technology, integrating 10/100 Ethernet MAC and PHY in a single package. It supports multiple protocols such as TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE, proven stable through real-world applications. W5300 provides 8 independent hardware SOCKETs and 128KB of internal buffer memory, allowing Ethernet applications to be developed through socket programming. It also offers direct and indirect BUS interfaces for easy MCU integration.
