The LAN9215 is a full-featured, single-chip 10/100 Ethernet controller designed for embeddedapplications where performance, flexibility, ease of integration and system cost control are required.The LAN9215 has been architected to provide the best price-performance ratio for any 16-bitapplication with medium performance requirements. The LAN9215 is fully IEEE 802.3 10BASE-T and802.3u 100BASE-TX compliant, and supports HP Auto-MDIX.The LAN9215 includes an integrated Ethernet MAC and PHY with a high-performance SRAM-likeslave interface. The simple, yet highly functional host bus interface provides a glue-less connection tomost common 16-bit microprocessors and microcontrollers as well as 32-bit microprocessors with a16-bit external bus. The LAN9215 includes large transmit and receive data FIFOs to accommodatehigh latency applications. In addition, the LAN9215 memory buffer architecture allows the most efficientuse of memory resources by optimizing packet granularity.
