The TCP/IP core is a market-proven hardwired TCP/IP stack with an integrated Ethernet MAC. The Hardwired TCP/IP stack supports the TCP, UDP, IPv4, ICMP, ARP, IGMP and PPPoE which has been used in various applications for years. W7500 suits best for users who need Internet connectivity for application.
