Intel 82571EB - dual port GbE (256-pin FCBGA) controller

The Intel 82571EB Gigabit Ethernet Controller for PCI Express is designed for high performance and low memory latency. The device is optimized to connect to a system Memory Control Hub (MCH) using up to four PCI Express lanes. Alternatively, the controller can connect to an Input/Output (I/O) Control Hub (ICH) that has a PCI Express interface. Wide internal data paths eliminate performance bottlenecks by efficiently handling large address and data words. Combining a parallel and pipelined logic architecture optimized for Gigabit Ethernet and for independent transmit and receive queues, the controller efficiently handles packets with minimum latency.
