Footprint Migration Differences
Unconnected Balls on XC3S50A
Table 73 summarizes any footprint and functionality
differences between the XC3S50A and the XC3S200A or
XC3S400A FPGAs that might affect easy migration between
these devices in the FT256 package. The XC3S200A and
XC3S400A have identical pinouts. The XC3S50A pinout is
compatible, but there are 52 balls that are different.
Generally, designs easily migrate upward from the
XC3S50A to either the XC3S200A or XC3S400A. If using
differential I/O, see Table 74. If using the BPI configuration
mode (parallel Flash), see Table 75.

Legend:
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.
