Footprint Migration Differences
Table 136
ences between the XC3S100E, the XC3S250E, and the
XC3S500E FPGAs that may affect easy migration between
devices in the CP132 package. There are 14 such balls. All

age.
The XC3S100E is duplicated on both the left and right sides
of the table to show migrations to and from the XC3S250E
and the XC3S500E. The arrows indicate the direction for
easy migration. A double-ended arrow (

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.

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.
The XC3S100E FPGA in the CP132 package has four fewer
BPI-mode address lines than the XC3S250E and
XC3S500E.
