WIZNET W5300

W5300 is a 0.18μm 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. 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 highspeed data communication. 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. 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.
