IPv4/IPv6,Hardwired TCP/IP w/ 802.3 Ethernet MAC and PHY, 8-sockets, Fast SPI/BUS
W6100-EVB is an evaluation board for W6100 chip based on the 32-bit ARM® Cortex™-M3 microcontroller. It is the easy way to develop internet connection for efficient and small embedded systems using W6100, WIZnet's hardwired TCP/IP embedded Ethernet controller. It has been designed to be hardware pin-compatible with 'Arduino shields' for the 'Arduino UNO...
W6100 Ethernet Shield is based on W6100. For more information about W6100, please visit W6100 Datasheet. This Ethernet Shield can be used on boards with an Arduino Pin Header Form factor.

W6300 is a WIZnet 10/100 TOE ethernet chip that combines the high-speed ethernet performance with Dual IPv4/v6 Hardware stack. To support ethernet performance up to 90Mbps and above, it supports 150MHz system clock and QSPI interface(including 4 Data lines). W6300 supports a total SRAM size of 64KB for 8 sockets, each has 4KB TX/RX buffer by default.
