Intel® 82541PI Gigabit Ethernet Controller: Product Brief

The Intelligent Way to Connect

High-performance, power-optimized Gigabit connection for mobile and desktop PCI-based designs
• 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® SingleDriver™ technology and footprint-compatibility with Intel® PRO 10/100 and 10/100/1000 Connections

The Intel®82541PI Gigabit Ethernet Controller provides optimized Gigabit networking for power-sensitive designs, such as mobile PC applications. This highly efficient controller, with enhanced power management, consumes less than 1.0W of power at Gigabit speeds. When no signal is detected on the wire, the controller reduces power consumption by switching to 100 or 10 and powering down the physical-layer circuitry (PHY). When a signal is detected, the controller automatically negotiates the connection to Gigabit, if available. To reduce the battery drain, the controller automatically switches the link to 100Mbps operation when on battery power.

The Intel 82541PI Gigabit Ethernet Controller enhances secure manageability and system health monitoring over the LAN with support for IPMI 1.5, ASF 2.0 and Advanced Pass Through. For IPMI designs, the on-board SMBus port can pass management traffic through the 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.
