Pinout Descriptions
Footprint Migration Differences
Table 151
ences between the XC3S500E, the XC3S1200E, and the
XC3S1600E FPGAs that may affect easy migration
between devices available in the FG320 package. There are
26 such balls. All other pins not listed in
tionally migrate between Spartan-3E devices available in
the FG320 package.
The XC3S500E is duplicated on both the left and right sides
of the table to show migrations to and from the XC3S1200E

DIFFERENCES
This pin is identical on 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.

Migration
and the XC3S1600E. 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.
