The 82559 10/100 MBps Fast Ethernet controller with an integrated
10/100 MBps physical layer device is Intel’s leading solution for
PCI board LAN designs.
It is designed for use in Network Interface Cards (NICs), PC LAN On
Motherboard (LOM) designs, embedded systems and networking system
products. The 82559 combines a low power and small package design
which is ideal for power and space constrained environments.

The 82559 continues Intel's platform LAN technology leadership
supporting: Advanced Configuration and Power Interface (ACPI) 1.20A
based power management, wake on Magic Packet, wake on interesting
packet, advanced System Management Bus (SMB) based manageability,
Wired for Management (WfM) 2.0 compliance, IP checksum assist,
PCI 2.2 compliance, and PC 98, PC 99, Server 99, and PC 2000
compliance.Designs based on the 82559 for desktop systems, notebooks,
PC cards and servers set a new industry standard for energy
conservation.
