Intel® 82540EP/82541(PI/GI/EI), 82562EZ(EX) Dual Footprint (AP-444)
Introduction
Intel currently supports several footprint compatible Ethernet options depending upon the target application. The term “footprint compatible” means that the silicon devices are all manufactured in a 15 mm x 15 mm, 196-ball grid array package with the same ball pattern. Many of the critical signal pin locations are identical, allowing designers to create a single LAN on Motherboard (LOM) design that accommodates all devices. This is a flexible, cost-effective, multipurpose design technique allowing maximized value while matching performance needs.
Note:
Since some of the signal pins have different usages, the term “pin-compatible” is not applicable.
Available LAN components with the same footprint include the 82540EP/82541xx Family of Gigabit Ethernet Controllers and the 82562EZ(EX) Platform LAN Connect components.
Note:
Throughout this document, the notation “82541xx” will be used to denote the 82541 Family of Gigabit Controllers (82541PI, 82541GI, and 82541EI).
The LAN component used on a specific platform depends on the end user’s need for connection speed and manageability. As the requirements change, footprint compatibility makes it possible to re-focus the platform without the need to redesign a new a motherboard.
