Microchip Technology LAN9500 Hi-Speed USB 2.0 to Ethernet Controller

Microchip LAN9500 Hi-Speed USB 2.0 to 10/100 Ethernet Controller provides a high-performance, cost-competitive USB to Ethernet connectivity solution containing an integrated 10/100 Ethernet PHY, Hi-Speed USB 2.0 PHY, Hi-Speed USB 2.0 controller, 10/100 Ethernet MAC, TAP controller, EEPROM controller, and FIFO controller in a compact 56-pin QFN package.

The LAN9500 supports ±8kV HBM and ±15kV air discharge ESD protection and requires only a single 25MHz crystal, which helps to keep BOM costs for external components to a minimum. An external MII and Turbo MII interface provides support for Fast Ethernet, HomePlug®, and HomePNA™ (HPNA) functionality.

This device features Microchip's NetDetach™ and UniClock™ technologies. NetDetach allows for up to a 25% reduction in system 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 costs by using a single 25MHz crystal for both USB and Ethernet connectivity, without the need for additional components when adding USB hubs.
