Microchip Technology LAN7500 USB 2.0 to Ethernet Controller

Microchip Technology LAN7500 USB 2.0 to 10/100/1000 Ethernet Controller provides 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 LAN7500 supports 10BASE-T, 100BASE-TX, and 1000BASE-T Ethernet and implements Control, Interrupt, Bulk-in, and Bulk-out USB endpoints. This device supports auto-negotiation, auto-polarity correction, HP Auto-MDIX support, and is compliant with IEEE 802.3/802.3u/802.3ab standards.

The LAN7500 includes Microchip 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 Microchip Technology LAN7500 USB 2.0 to 10/100/1000 Ethernet Controller is offered in a 56-pin QFN package. The LAN7500i variant features an extended -40°C to 85°C industrial operating temperature range.
