Chip Ties USB To Ethernet

The LAN9500 USB-to-Ethernet bridge is one of a number of new Ethernet offerings from SMSC. It incorporates a Hi-Speed USB 2.0 controller and physical layer (PHY) with a 10/100 Ethernet interface that includes an auto-MDIX PHY. The LAN9420 PCI Ethernet controller is optimized for 32-bit microcontrollers. It also has the auto-MDIX PHY. The integrated scattergather DMA and IRQ support can significantly reduce CPU overhead while delivering increased throughput. The LAN931x switches target low-port-count applications with two- and three-port versions. Versions are available with a 16- and 32-bit, non-PCI interface that eliminates the need for an Ethernet interface chip or a microcontroller with on-chip Ethernet support.
