Footprint Migration Differences
Table 23
ences between the XC3S250E, the XC3S500E, and the
XC3S1200E FPGAs that may affect easy migration
between devices in the FG256 package. There are 26 such
balls. All other pins not listed in
migrate between Spartan-3E devices available in the FT256
package.
The XC3S250E is duplicated on both the left and right sides
of the table to show migrations to and from the XC3S500E

DIFFERENCES
summarizes any footprint and functionality differ-
This pin is identical on both the device on the left and the right.
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.

and the XC3S1200E. The arrows indicate the direction for
easy migration. A double-ended arrow (
the two pins have identical functionality. A left-facing arrow
( ) indicates that the pin on the device on the right uncon-
ditionally migrates to the pin on the device on the left. 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.
