W5200
W5200 
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 application that uses 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. 
W5200  uses  a  32Kbytes 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.   
Using the only 4 pins of SPI to connect with MCU, it is possible to design for small form 
factor system with the MCU’s I/O pin limit. 
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.
