Intel 82541 Gigabit Ethernet Controllers

Intel's 82541 Gigabit Ethernet Controllers are single, compact components with an integrated Gigabit Ethernet Media Access Control (MAC) and physical layer (PHY) functions. These are designed for embedded communication, network devices such as web kiosks, and Point-of-Sale terminal designs and desktop, workstation and mobile PC Network designs. Each allows for a Gigabit Ethernet implementation in a very small area that is footprint compatible with current generation 10/100 Mbps Fast Ethernet designs. Each controller is capable of transmitting and receiving data at rates of 1000 Mbps, 100 Mbps, or 10 Mbps. In addition to managing MAC and PHY layer functions, these provide a 32-bit wide direct Peripheral Component Interconnect (PCI) 2.3 compliant interface capable of operating at 33 or 66 MHz.
