The gate level integrated TCP/IP Hardwired-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.
The SPI (up to 80 MHz) 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.
