Based on the Wiznet W5100 ethernet chip, the new shield provides a network (IP) stack capable of both TCP and UDP, and supports up to four simultaneous socket connections.

It’s based on the same WizNet W5100 chip that was used in the tiny ethernet board we covered earlier. The W5100 handles the full IP stack and can do TCP or UDP with four simultaneous sockets.

Developed using the W3150A TCP/IP stack IC, the iEthernet W5100 10/100 Ethernet-controller IC includes a hard-wired TCP/IP core and a PHY (physical-layer) interface. This memory-mapped hardware device ...
