High-performance, power-optimized Gigabit connection for mobile and desktop PCI-based designs
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.
The Intel 82541PI combines Intel's fifth-generation Gigabit MAC design with fully integrated PHY to provide a standard IEEE 802.3 Ethernet interface for 1000BASE-T, 100BASE-TX and 10BASE-T applications. In addition, the controller provides a direct Peripheral Component (PCI) Interconnect designed to be compliant with the PCI 2.3 bus up to 66MHz. Packaged in a 15x15mm PBGA, the Intel 82541PI Gigabit Ethernet Controller is footprint-compatible with the Intel® 82551QM Fast Ethernet Controller and Intel® 82562EX and 82562EZ devices. Footprint-compatibility, plus Intel SingleDriver technology allow for a flexible Gigabit Ethernet or Fast Ethernet implementation on the same motherboard layout.
With built-in power management capabilities and enhanced manageability, the Intel 82541PI Gigabit Ethernet Controller can help extend battery life for mobile PC users, giving your designs a competitive edge for tomorrow's mobile PCs.
