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.

Target Applications

The W5100 is well suited for many embedded applications, including:

Home Network Devices: Set-Top Boxes, PVRs, Digital Media Adapters

Serial-to-Ethernet: Access Controls, LED displays, Wireless AP relays, etc.

Parallel-to-Ethernet: POS / Mini Printers, Copiers

USB-to-Ethernet: Storage Devices, Network Printers

GPIO-to-Ethernet: Home Network Sensors

Security Systems: DVRs, Network Cameras, Kiosks

Factory and Building Automations

Medical Monitoring Equipments

Embedded Servers
