User I/Os by Bank
Table 79 and Table 80 indicate how the user-I/O pins are distributed between the four I/O banks on the FGG484 package.
The AWAKE pin is counted as a dual-purpose I/O.
Footprint Migration Differences
Table 81 summarizes the three footprint and functionality differences between the XC3S700AN and the XC3S1400AN
FPGAs that can affect migration between devices available in the FGG484 package. All other pins unconditionally migrate
between the Spartan-3AN devices available in the FGG484 package.
Spartan-3AN FPGAs are pin compatible with the same density Spartan-3A FPGAs in the FG(G)484 package, although the
Spartan-3A FPGAs require an external configuration source.
In Table 81, the arrow (
) indicates that this pin can unconditionally migrate from the device on the left to the device on the
right. Migration in the other direction is possible depending on how the pin is configured for the device on the right.
