Intel® 82550 Fast Ethernet Controller
Overview
 
The Intel® 82550 Fast Ethernet Controller is a third generation fully integrated Fast Ethernet Media Access Controller (MAC)/ Physical Layer (PHY) device. The MAC offers a low-cost, high-performance 10/100 Mbps LAN solution. In addition, the 82550 requires low real estate, which is important when competing for precious board space. The 82550's baseline functionality is equivalent to that of the 82559 with the addition of an integrated IP Security (IPSec) encryption engine, and Alert on LAN* 2 functionality.

The 82550, with an integrated IP Security (IPSec) encryption engine and Alert on LAN functionality, is Intel's premium 10/100 Mbps network connectivity solution. It is designed for use in Network.

Interface Cards (NICs) and PC LAN on Motherboard (LOM) designs. The 82550 combines advanced security and manageability features to provide a secure and easily managed Fast Ethernet connectivity solution for today's networked environment.

Intel® 82550 The 82550 continues Intel's platform LAN technology leadership by integrating the following features: Triple Data Encryption Standard (3DES) IPSec encryption engine, Advanced Configuration and Power Interface (ACPI) 1.2A based power management, wake on Magic Packet*, wake on interesting packet and advanced System Management Bus (SMB) based manageability. The 82550 complies with Wired for Management (WfM) Specification 2.0, PC 01 and Server 00 specifications. The 82550 is pin-compatible with the 82559, allowing these designs to be upgraded.
