The LAN9218-MT is a high-performance single-chip 10/100 Ethernet Controller with HP Auto-MDIX support. It has been specifically architected to provide the highest performance possible for any given architecture. The LAN9218 is fully IEEE 802.3 10Base-T and 802.3u 100Base-TX compliant and supports HP Auto-MDIX. It 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 and 32-bit microprocessors and microcontrollers. It includes large transmit and receive data FIFOs with a high-speed host bus interface to accommodate high bandwidth, high latency applications. In addition, the LAN9218 memory buffer architecture allows highly efficient use of memory resources by optimizing packet granularity. It supports numerous power management and wakeup features.
