Pinout Descriptions
User I/Os by Bank
Table 138
user-I/O pins are distributed between the four I/O banks on
the TQ144 package.

Footprint Migration Differences
Table 140
ences between the XC3S100E and the XC3S250E FPGAs
that may affect easy migration between devices. There are
four such pins. All other pins not listed in
ditionally migrate between Spartan-3E devices available in
the TQ144 package.

This pin can unconditionally migrate from the device on the left to the device on the right. Migration in the other direction may be
possible depending on how the pin is configured for the device on the right.

The arrows indicate the direction for easy migration. For
example, a left-facing arrow indicates that the pin on the
XC3S250E unconditionally migrates to the pin on the
XC3S100E. It may be possible to migrate the opposite
direction depending on the I/O configuration. For example,
an I/O pin (Type = I/O) can migrate to an input-only pin
(Type = INPUT) if the I/O pin is configured as an input.
