USB 2.0 to 10/100 Ethernet Controller
SMSC LAN950x Family 3 Revision 1.1 (04-18-13)
PRODUCT PREVIEW
Overview
The LAN950x is a high performance Hi-Speed USB 2.0 to 10/100 Ethernet controller. With applications
ranging from embedded systems, set-top boxes, and PVR’s, to USB port replicators, USB to Ethernet
dongles, and test instrumentation, the device is a high performance and cost competitive USB to
Ethernet connectivity solution.
The LAN950x contains an integrated 10/100 Ethernet PHY, USB PHY, Hi-Speed USB 2.0 device
controller, 10/100 Ethernet MAC, TAP controller, EEPROM controller, and a FIFO controller with a total
of 30 KB of internal packet buffering.
The internal USB 2.0 device controller and USB PHY are compliant with the USB 2.0 Hi-Speed
standard. The device implements Control, Interrupt, Bulk-in, and Bulk-out USB Endpoints.
The Ethernet controller supports auto-negotiation, auto-polarity correction, HP Auto-MDIX, and is
compliant with the IEEE 802.3 and IEEE 802.3u standards. An external MII interface provides support
for an external Fast Ethernet PHY, HomePNA, and HomePlug functionality.
Multiple power management features are provided, including various low power modes and "Magic
Packet", "Wake On LAN", and "Link Status Change" wake events. These wake events can be
programmed to initiate a USB remote wakeup.
An internal EEPROM controller exists to load various USB configuration information and the device
MAC address. The integrated IEEE 1149.1 compliant TAP controller provides boundary scan via JTAG.
