Intel® 82541 Gigabit Ethernet Controller Family: Datasheet
The Intel® 82541(PI/GI/EI) Gigabit Ethernet is a single, compact component with an integrated Gigabit Ethernet Media Access Control (MAC) and physical layer (PHY) functions. For desktop, workstation, and mobile PC Network designs with critical space constraints, the Intel® 82541(PI/GI/EI) Gigabit Ethernet Controller allows for a Gigabit Ethernet implementation in a very small area that is footprint compatible with current generation 10/100 Mbps Fast Ethernet designs.
The Intel® 82541(PI/GI/EI) integrates fourth generation gigabit MAC design with fully integrated, physical layer circuitry to provide a standard IEEE 802.3 Ethernet interface for 1000BASE-T, 100BASE-TX, and 10BASE-T applications (802.3, 802.3u, and 802.3ab). The 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, the controller provides a 32-bit wide direct Peripheral Component Interconnect (PCI) 2.3 compliant interface capable of operating at 33 or 66 MHz.
The 82541(PI/GI/EI) also incorporates the Clock Run protocol and hardware-supported downshift capability to two-pair and three-pair 100 Mbps operation. These features optimize mobile applications.
The 82541(PI/GI/EI) on-board System Management Bus (SMB) port enables network manageability implementations required by information technology personnel for remote control and alerting via the Local Area Network (LAN). With SMB, management packets can be routed to or from a management processor. The SMB port enables industry standards, such as Intelligent Platform Management Interface (IPMI) and Alert Standard Forum (ASF) 2.0, to be implemented using the 82541(PI/GI/EI). In addition, on-chip ASF 2.0 circuitry provides alerting and remote control capabilities with standardized interfaces.
