Product Brief Intel 82541PI Gigabit Ethernet Controller ® High-performance, power-optimized Gigabit connection for mobile and desktop PCI-based designs The Intelligent Way to Connect Longer battery life through reduced power usage and enhanced power management System health monitoring and authenticated remote power control with ASF 2.0 Design flexibility with Intel® SingleDriverTM technology and footprint-compatibility with Intel® PRO 10/100 and 10/100/1000 Connections generation Gigabit MAC design with fully The Intel 82541PI Gigabit Ethernet Controller integrated PHY to provide a standard IEEE provides optimized Gigabit networking for 802.3 Ethernet interface for 1000BASE-T, power-sensitive designs, such as mobile PC 100BASE-TX and 10BASE-T applications. applications. This highly efficient controller, with In addition, the controller provides a direct enhanced power management, consumes less Peripheral Component (PCI) Interconnect than 1.0W of power at Gigabit speeds. When designed to be compliant with the PCI 2.3 no signal is detected on the wire, the controller bus up to 66MHz. Packaged in a 15x15mm reduces power consumption by switching to PBGA, the Intel 82541PI Gigabit Ethernet 100 or 10 and powering down the physical- Controller is footprint-compatible with the layer circuitry (PHY). When a signal is detected, Intel® 82551QM Fast Ethernet Controller the controller automatically negotiates the con- and Intel® 82562EX and 82562EZ devices. nection to Gigabit, if available. To reduce the Footprint-compatibility, plus Intel SingleDriver battery drain, the controller automatically technology allow for a flexible Gigabit Ethernet switches the link to 100Mbps operation when or Fast Ethernet implementation on the same on battery power. motherboard layout. The Intel 82541PI Gigabit Ethernet Controller With built-in power management capabilities enhances secure manageability and system and enhanced manageability, the Intel 82541PI health monitoring over the LAN with support Gigabit Ethernet Controller can help extend for IPMI 1.5, ASF 2.0 and Advanced Pass battery life for mobile PC users, giving your Through. For IPMI designs, the on-board SMBus designs a competitive edge for tomorrow’s port can pass management traffic through the mobile PCs. ® Intel in Communications The Intel 82541PI combines Intel’s fifth- controller to a management device, such as a Baseboard Management Controller (BMC). Alternatively, ASF 2.0 provides manageability without the cost burden of external hardware via standardized interfaces. ASF 2.0 circuitry provides advanced system health and security alerting plus authenticated remote power control capabilities.
