The LAN9218(i) 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 LAN9218(i) has been specifically architected to provide the highest performance possible for any given architecture. The LAN9218(i) is fully IEEE 802.3 10BASE-T and 802.3u 100BASE-TX compliant, and supports HP Auto-MDIX.

The LAN9218(i) 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. The LAN9218(i) 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(i) memory buffer architecture allows the most efficient use of memory resources by optimizing packet granularity.

The  EEPROM device from Microchip comes with a factory programmed, globally unique EUI-48™ MAC Address. This Ethernet controller will automatically detect and load the EUI-48™ node address from the  EEPROM at start-up or reset.
