The W5100 is a full-featured, single-chip 10/100 Ethernet controller designed for embedded applications where ease of integration, stability, performance, area and system cost-control are required. The W5200 has been designed to facilitate easy implementation of internet connectivity without an OS. The W5200 is IEE 802.3 10BASE-T and 802.3u 100BASE-TX compliant.

For easy integration, using minimal I/O pins, the W5200 includes a high-speed SPI interface.

The W5200 chip is a Hardwired TCP/IP embedded Ethernet controller that enables easier internet connection for embedded systems using SPI (Serial Peripheral Interface).

W5200 suits best for users who need Internet connectivity for applications that use a single chip to implement TCP/IP Stack, 10/100 Ethernet MAC and PHY. The W5200 is composed of a fully hardwired, market-proven TCP/IP stack and an 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 many years. The W5200 uses a 32 Kbyte internal buffer as its data communication memory. By using W5200, users can implement the Ethernet application they need by using a simple socket program instead of handling a complex Ethernet Controller.

SPI (Serial Peripheral Interface) is provided for easy integration with the external MCU. The W5200 SPI supports a high-speed SPI capable of communicating over SPI at up to 80 MHz.  In order to reduce power consumption of the system, W5200 provides WOL (Wake on LAN) and power-down mode. To wake up during WOL, W5200 should be received magic packet, which is the Raw Ethernet packet.
