High-performance Internet Connectivity Solution
W5300
W5300 is a 0.18 µm CMOS technology single chip into which 10/100 Ethernet controller, MAC,
and TCP/IP are integrated. W5300 is designed for Internet embedded applications where easy
implementation, stability, high performance, and effective cost are required.
W5300's target application is the embedded internet solution requiring high performance such
as multi-media streaming service. Comparing to existing WIZnet chip solution, W5300 has been
improved in memory and data process. W5300 is the most appropriate to the products of IPTV,
IP-STB and DTV transferring multi-media data with high-capacity.
The Internet connectivity can be implemented easily and quickly only with single chip having
TCP/IP protocol and 10/100 Ethernet MAC & PHY.
High-Performance Hardware TCP/IP single chip solutions
WIZnet retains the technology of full hardware logic of communication protocols such as TCP,
UDP, IPv4, ICMP, IGMP, ARP and PPPoE. In order to provide high-performing data
communication, the data communication memory is extended to 128Kbyte and 16bit bus
interface is supported in W5300. Users can utilize independent 8 hardware SOCKETs for high-
speed data communication.
More flexible memory allocation for various applications
The memory for data communication can be allocated to each SOCKET in the range of
0~64Kbytes. It is more flexible for users to utilize the memory according to their application.
Users can develop more efficient system by concentrating on the application of high
performance.
Easy to implements for beginners
W5300 supports BUS interface as the host interface. By using direct and indirect access
methods, W5300 can easily interfaced to the host as like SRAM memory. The data
communication memory of W5300 can be accessed through TX/RX FIFO registers that exist in
each SOCKET. With these features, even beginners can implement Internet connectivity by
using W5300.
