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 con-
nection 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.
