The gate level integrated TCP/IP Hardware-Stack of the W5500 supports all level-3 and -4 protocol layers like TCP, UDP, IPv4, ICMP, ARP, IGMP, PPPoE (ADSL) and Multicast. The HW-Stack also processes the handshaking and the controller is relieved of all protocol tasks. As TX/RX buffer 32kByte dual-port SRAM are available for up to 8 simultaneous Internet connections.

As special function the W5500 supports a power down mode and Wake-on-LAN (WoL).

The controller-interface (up to 80 MHz SPI) supports data rates up to 10MBits/s.
Open source drivers and examples for different μC-platforms are available. No operating system is needed even for WEB-, FTP- or DHCP-client or server.

  • Hardwired TCP/IP:
    • ŸTCP, UDP, ICMP, IGMP, IPv4, ARP, Ethernet
