1.6.10.4 Intel 82541PI Gigabit Ethernet Controller (Optional)
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.
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.
