$Features & Applications

Established in 1998, WIZnet’s core technology ‘TCP/IP Offload Platform’ is an ASSP and silicon-proven IP for custom ASIC, which best fits OS-less devices and is compatible with any Embedded OS. Their fully hardwired TCP/IP algorithm guarantees line speed by on-the-fly processing architecture that is independent of any main processor. This technology has eliminated the need for a main processor by offloading TCP/IP processing, enhancing the overall system performance, particularly in multimedia streaming applications.

WIZnet’s hardwired TCP/IP chip has been adopted worldwide both in OS-less devices (esp. DVR, Remote Control) and OS-based applications (esp. STB, DTV). It provides higher performance and stability than any software internet connectivity solution.

Fully Hardwired Newtwork protocol Embedded Ethernet Controller designed for high speed required
embedded system


  • Supports hardwired TCP/IP protocols : TCP,UDP, ICMP, IPv4, ARP, IGMPv2, PPPoE, Ethernet
