MICROCHIP LAN9117-MT

The LAN9117 is a full-featured, single-chip 10/100 Ethernet controller designed for embedded applications where performance, flexibility, ease of integration and system cost control are required. The LAN9117 has been specifically architected to provide the highest performance possible for any 16-bit application. The LAN9117 is fully IEEE 802.3 10BASET and 802.3u 100BASE-TX compliant. The LAN9117 includes an integrated Ethernet MAC and PHY with a high-performance SRAM-like slave interface. The simple, yet highly functional host bus interface provides a glue-less connection to most common 16-bit microprocessors and microcontrollers as well as 32-bit microprocessors exposing a 16-bit external bus. The LAN9117 includes large transmit and receive data FIFOs with a high-speed host bus interface to accommodate high bandwidth, high latency applicatio
