W6100 IPv4/IPv6 Dual-Stack Hardwired TCP/IP Controller

The W6100 is an advanced successor to the W5500, distinguished by supporting both IPv4 and IPv6 dual stacks entirely in hardware. It integrates a 10/100 MAC and PHY with 8 hardware sockets and is pin-compatible with the W5100S — an ideal choice when devices must migrate to IPv6.
