Description
AI
Microchip's LAN9514/LAN9514i are the industry's first fully-integrated, Hi-Speed USB 2.0 hub and high-performance 10/100 Ethernet controllers. The LAN9514/LAN9514i are specifically designed to provide system architects with a low-cost, power-efficient, small-footprint USB to Ethernet and multi-port USB connectivity solution in a single package.
The LAN9514/LAN9514i contain a Hi-Speed USB 2.0 hub with four fully-integrated downstream USB 2.0 PHYs, an integrated upstream USB 2.0 PHY, a 10/100 Ethernet MAC/PHY controller, and an EEPROM controller. It offers Microchip's highest level of USB 2.0 and 10/100 Ethernet compliance and interoperability. Additionally, the LAN9514/LAN9514i devices simplify system design by leveraging the existing USB stack and reducing the PCB footprint by up to 65% compared to discrete competitive solutions. 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.
