LAN7500
Hi-Speed USB 2.0 to 10/100/1000 Gigabit Ethernet Controller
SMSC’s LAN7500 is a Hi-Speed USB 2.0 to 10/100/1000 Gigabit Ethernet controller providing a high-performance and costeffective USB to Ethernet connectivity solution. The LAN7500 contains an integrated 10/100/1000 Gigabit Ethernet PHY, USB
PHY, Hi-Speed USB 2.0 device controller, 10/100/1000 Gigabit Ethernet MAC, TAP controller, EEPROM controller and a FIFO
controller with a total of 32KB internal packet buffering. The device supports 10BASE-T, 100BASE-TX and 1000BASE-T Ethernet
and implements Control, Interrupt, Bulk-in and Bulk-out USB endpoints. The Ethernet controller supports auto-negotiation, autopolarity correction, HP Auto-MDIX* support and is compliant with IEEE 802.3/802.3u/802.3ab standards.
USB-based networking provides flexibility for the routing and placement of network connections anywhere in the system. USB-based
solutions leverage the existing USB stack for the Ethernet driver. The LAN7500 is also available with a wide range of drivers including
Windows®, Mac® and Linux®.
The LAN7500 also offers SMSC’s NetDetach™ and UniClock™ technologies. NetDetach allows for up to a 25% reduction in power
by enabling the host CPU to enter a low-power state when Ethernet is inactive. UniClock simplifies the clocking scheme and reduces
system BOM cost by using a single 25MHz crystal for both USB and Ethernet connectivity. Multiple power management features are
provided, including various low-power modes and Magic Packet™, Wake-on LAN (WOL) and Link Status Change wake events. These
wake events can be programmed to initiate a USB remote wakeup. The device is available in commercial (0º to 70ºC) and industrial
temperature range (-40º to 85ºC) options.
SMSC’s complimentary and confidential LANCheck® and USBCheckTM online design review services are available for customers who
have selected our products for their application design-in**.
