W5100 Datasheet
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 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 of consideration for handling Ethernet Controller, but
simple socket programming is required.
For easy integration, three different interfaces like memory access way, called direct,
indirect bus and SPI, are supported on the MCU side.
