Footprint Migration Differences
There are multiple migration footprint differences between
the XC3SD1800A and the XC3SD3400A in the FG676
package. These migration footprint differences are shown in
Tabl e 6 7 . Migration from the XC3S1400A Spartan-3A
device in the FG676 package to a Spartan-3A DSP device
in the FG676 package is also possible. The XC3S1800A pin
migration differences have been added to Ta bl e 6 7 for
designs migrating between these devices.
