82541PI(ER) and 82562GZ(GX) Dual Footprint LOM Design Guide

Pin Number to Signal Mapping with Population
Options
lists the pin names for the three controllers and the corresponding shared ball reference
value. Note that the 82541PI(ER) pin name in the 82541PI(ER) Datasheet/Design Guide is slightly
different from the signal name on the reference schematics. The Datasheet/Design Guide signal
names maintain consistency with the 64-bit gigabit controller naming conventions, while the
schematic names follow the conventions used by our engineers on their design tools.
