商品详细描述

Microchips LAN7500 is a Hi-Speed USB 2.0 to 10/100/1000 Gigabit Ethernet controller providing a high-performance and cost-effective 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, 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 LAN7500 is also available with a wide range of drivers including Windows?, Mac? and Linux?.

The LAN7500 also offers Microchip’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 (0° to 70°C) and industrial temperature range (-40° to 85°C) options.

Microchips complimentary and confidential LANCheck? and USBCheck? online design review services are available for customers who have selected our products for their application design-in*.

?HP Auto-MDIX eliminates the need for special "crossover" cables when connecting LAN devices together.
