Microchip's LAN7800 is a Super Speed USB 3.1 Gen 1 to 10/100/1000 Gigabit Ethernet bridge providing an ultra high-performance and cost-effective USB to Ethernet connectivity solution. The LAN7800 contains an integrated 10/100/1000 Gigabit Ethernet PHY, USB PHY, Hi-Speed USB 2.0 device controller, SuperSpeed USB3.1 Gen 1 device controller, 10/100/1000 Gigabit Ethernet MAC, Integrated OTP, EEPROM controller. 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, auto-polarity 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 LAN7800 is also available with a wide range of drivers including Windows®, Mac® and Linux®.
The LAN7800 also offers Microchip’s NetDetach™ and UniClock™ technologies. NetDetach allows for reduced 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. MSFT QOAC (alway On Always Connected) is also supported. These wake events can be programmed to initiate a USB remote wakeup and if desired, also generate a hardware PME event. The device is available in commercial (0° to 70°C) and industrial temperature range (-40° to 85°C) options.
