The W5100 Ethernet Module is a full-featured, single-chip.  This Ethernet controller is designed for embedded applications; where ease of integration, stability, performance, area.

The W5100 Ethernet Module has been designed to facilitate easy implementation of Internet connectivity without OS. W5100 is IEEE 802.3 17 BASE-T and 802.3u 10 BASE-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 application for several years. A 16kbytes internal buffer is included for data transmission.

Features :

• Support Hardwired TCP/IP Protocols: TCP, UDP, ICMP, IPv4 ARP, IGMP, PPPoE, Ethernet
• 10BaseT/100BaseTX Ethernet PHY embedded
• Auto-Negotiation (Full-duplex and half duplex)
• Support Auto MDI/MDIX
• Simultaneously Supports to 4 independent sockets
• Not support to IP Fragmentation
• Internal 16Kbytes Memory for Tx/Rx Buffers
• 0.18 µm CMOS technology
• 3.3V operation with 5V I/O signal tolerance
• Provide Serial Peripheral Interface (SPI MODE 0, 3) support
• Support ADSL connection (with support PPPoE Protocol with PAP/CHAP Authentication mode)
