LAN9211 - High-Performance Small Form Factor 56-Pin Single-Chip Ethernet Controller with HP Auto-MDIX
The LAN9211 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 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, and supports HP Auto-MDIX.
The LAN9211 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 with a 16-bit external bus. The integrated checksum offload engines enable the automatic generation of the 16-bit checksum for received and transmitted Ethernet frames, offloading the task from the CPU. The LAN9211 also includes large transmit and receive data FIFOs to accommodate high latency applications. In addition, the LAN9211 memory buffer architecture allows the most efficient use of memory resources by optimizing packet granularity.
