Spartan-3A DSP FPGA Family: Pinout Descriptions
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 Table 70. 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 Table 70 for designs migrating between these devices.
