Footprint Compatibility

The Intel 82540EP Gigabit Ethernet Controller and the Intel 82551QM Fast Ethernet Controller are all
manufactured in a footprint compatible 15 mm x 15 mm (1-mm pitch), 196-ball grid array package.
Many of the critical signal pin locations on the 82540EM and the 82551QM are identical, allowing
designers to create a single design that accommodates any one of these parts. Because the usage of some
pins on the 82540EM differs from the usage on the 82551QM, the parts are not referred to as "pin
compatible." The term "footprint compatible" refers to the fact that the parts share the same package
size, same number and pattern of pins, and layout of signals. This allows for flexible, cost effective, and
multipurpose design.
Design guidelines are provided for each required interface and connection. Refer to the following
figures and the subsequent table for the corresponding section of this design guide.
