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.
