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 and physical layer (PHY).
Using W5100 doesn't need to consider the control of Ethernet, it only needs a simple port (Socket) programming.
Specification:
3.3 V power supply, IO is compatible with 5 V voltage signal
A variety of interfaces can choose: direct bus, indirect bus, and the SPI bus., Support hardware TCP/IP protocol stack, supports TCP, UDP, ICMP and IGMP, IPv4, ARP, PPPoE.
Internal integration 16-byte transceiver cache
Indicate the output, a variety of information including RX and TX, Full/Duplex, Collision, Link, Speed
