W5100 Ethernet Module
The W5100 is a full-featured, single-chip Internet-enabled 10/100 Ethernet controller designed for embedded applications where ease of integration, stability, performance, area, and system cost control are required. The W5100 has been designed to facilitate the easy implementation of Internet connectivity without OS. The W5100 is IEEE 802.3 10BASE-T and 802.3u 100BASE-TX compliant.
The W5100 includes fully hardwired, market-proven TCP/IP stack and integrated Ethernet MAC & PHY. Hardwired TCP/IP stack supports TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE which has been proven in various applications for several years. 16Kbytes internal buffer is included for data transmission. No need for consideration for handling Ethernet Controller, but simple socket programming is required.
