®
Product Brief
Overview
The Intel
®
82550 Fast Ethernet Multifunction PCI/CardBus 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 10/100Mbps 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.
Product Description
The 82550, with an integrated IP Security (IPSec) encryption engine and Alert on LAN functionality,
is Intel’s premium 10/100 network connectivity solution. It is designed for use in Network Interface
Cards (NICs), PC LAN on Motherboard (LOM) designs, embedded systems, and networking
systems products. The 82550 combines advanced security and manageability features to provide a
secure and easily managed Fast Ethernet connectivity solution for today’s networked environment.
The 82550 continues Intel’s platform LAN technology leadership by integrating the following features:
Triple Data Encryption Standard (3DES) IPSec encryption engine, Alert on LAN 2 functionality
and Advanced Configuration and Power Interface (ACPI) 1.2A-based power management. It also
supports wake on Magic Packet*, wake on interesting packet, and advanced System Management
Bus (SMB) 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.
