The LAN9211 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 LAN9211 has been specifically designed to provide the highest performance possible for any 16-bit application.The LAN9211 is fully IEEE 802.3 10BASE-T and 802.3u 100BASE-TX compliant, andsupports HP Auto-MDIX.The LAN9211 includes an integrated Ethernet MAC and PHY with a high-performance SRAM-like slaveinterface. The simple, yet highly functional host bus interface provides a glue-less connection to mostcommon 16-bit microprocessors and microcontrollers as well as 32-bit microprocessors with a 16-bitexternal bus. The integrated checksum offload engines enable the automatic generation of the 16-bitchecksum for received and transmitted Ethernet frames, offloading the task from the CPU. TheLAN9211 also includes large transmit and receive data FIFOs to accommodate high latencyapplications. In addition, the LAN9211 memory buffer architecture allows the most efficient use ofmemory resources by optimizing packet granularity.
