Ethernet
Microchip's Ethernet Product Offerings
Ethernet is a ubiquitous, high throughput, low-cost networking technology that has become the standard for connectivity from factory floors to office environments to home entertainment systems. With Microchip’s acquisition of SMSC, we have expanded our portfolio to include products that are particularly well-suited for embedded applications supporting non-PCI designs. SMSC’s tradition as a reliable, worldwide supplier with significant expertise in providing leading edge, highly-integrated Ethernet devices ensures Microchip’s long-term support for a variety of products that can enable customers to quickly add high-performance Ethernet connectivity to their designs.
USB to Ethernet Controllers
The USB to Ethernet connection takes advantage of the ubiquity and speed of USB, replacing older means of transferring information. USB-based networking technology offers a cost-effective and smart design alternative to traditional PCI/PCI-Express networking solutions due to the flexibility of routing and placement of Ethernet and USB connectivity ports.
Microchip integrates Hi-Speed USB 2.0 and high-performance 10/100/1000 Ethernet in its line of standalone USB to Ethernet controllers and USB to Ethernet hub controllers.

ARCNET Controllers
ARCNET has many characteristics that make it ideal for industrial and embedded networking environments. This is due to the deterministic token passing scheme nature of ARCNET, its high reliability and fault tolerance, and its adaptability to a wide variety of cabling media and configurations. Microchip is the market leader in ARCNET devices and has a full spectrum of solutions to meet any customer's price and performance needs.
CircLink, an ARCNET derivative, further improves on the protocol by eliminating the need for an external processor and is optimized as a wire-replacement technology inside industrial and commercial machines.
