Architectural Overview

External Architecture Block Diagram

The 82541(PI/GI/EI) architecture is a derivative of the 82542, 82543, and 82544 designs that

provided Media Access Controller (MAC) functionality as well as an integrated 10/100/1000Mbps

copper PHY. The 82541(PI/GI/EI) family architecture now adds SMBus-based manageability and

an integrated ASF controller functionality to the MAC.
