W5100 Ethernet Module

W5100 is a versatile single-chip network interface chip, internal integration 10/100 Ethernet controller, mainly used in high integration, high stability, high performance and low cost of embedded systems.Using W5100 can realize no Internet connection of the operating system.W5100 with IEEE802.3 10 base-t and 802.3 u 100 base - TX compatible.W5100 internal integration of the whole hardware, and after many years of market validation of TCP/IP protocol stack, Ethernet medium transport layer (MAC) and physical layer (PHY).Using W5100 don't need to consider the control of Ethernet, only need for a simple port (Socket) programming.
