WIZnet
Connecting Devices and Igniting Interconnected Futures

Imagine a data transmission autobahn, where information zips along at thought’s speed, unhampered by the usual digital gridlock.

Data transfer often resembles a congested highway plagued with security risks and inefficiencies in the current landscape.

WIZnet aims to turn the data transfer pathways from congested ‘highways’ to seamless data transmission ‘autobahns’ by merging TCP/IP, MAC, and PHY into a single-chip solution.

Traditional systems handle these elements separately, leading to slower and less efficient data processing. Integrating all three streamlines the data journey and enhances security and speed, setting a new standard in the industry.

The integration represents a technological leap, offering a smarter, more reliable solution for modern data needs and significantly reducing conventional multi-chip setups’ complexities and vulnerabilities.

Superior to traditional software, WIZnet’s single-chip design also simplifies the creation of boards and the replacement of outdated components, eliminating the need for a separate PHY chip.

“The advancement is more than just an upgrade; it’s a complete overhaul of the data transmission process, propelling businesses and users into an era of speed and security,” says Jake Lee, global director of operations.

Revolutionizing Network Communication with TCP/IP TOE

The technology behind WIZnet’s offerings is the hardwired TCP/IP Offload Engine (TOE), which minimizes internet frame loss and streamlines data traffic in embedded systems by processing TCP/IP protocols through separate, dedicated resources. It stably provides fast network speeds by designing processors and their operation methods for the four network layers—from the physical layer to the transport layer— with hardware logic. This approach ensures network speeds more than twice as fast as those of software TCP/IP solutions. It maintains over 80 percent communication stability even under traffic surges and network attacks like DDoS, Smurf, and Spoofing.

This means that a system’s performance is no longer a bottleneck in network communication, allowing for faster and more reliable data handling. With TOE, even systems with limited processing power can achieve robust networking capabilities, which is crucial for IoT devices and other connected technologies.

The WIZnet Ethernet chip, commercialized as an ASIC with products like the W5500, W5100S, and W6100 models, illustrates this with features tailored to speed and efficiency. It supports a hardware-based TCP/IPv4v6 stack for 100/10 Ethernet communication, enabling low-cost IoT solutions. It also offers compatibility with various hardware platforms, like Arduino and ARM embed, ensuring that developers can quickly and easily implement these chips into their designs.

Performance tests have shown that TOE significantly outperforms software TCP/IP, especially in environments with low-spec embedded systems. For instance, using the IPERF tool, TOE achieved up to 90 Mbps in a 100 Mbps network bandwidth scenario, while software TCP/IP reached only 32 Mbps. This disparity illustrates the efficiency of WIZnet’s hardware-based approach, especially in speed.

Continuously developed, TOE technology has secured 32 technology patents, further solidifying WIZnet’s commitment to advanced and reliable networking solutions.
