User I/Os by Bank
Table 88 indicates how the 502 available user-I/O pins are
distributed between the four I/O banks on the FG676
package. The AWAKE pin is counted as a dual-purpose I/O.
Footprint Migration Differences
The XC3S1400A FPGA is the only Spartan-3A device
offered in the FG676 package. However, Table 89
summarizes footprint and functionality differences between
the XC3S1400A and the XC3SD1800A in the Spartan-3A
DSP family. There are 17 unconnected balls in the
XC3S1400A that become 16 input-only pins and one I/O pin
in the XC3SD1800A. All other pins not listed in Table 89
unconditionally migrate between the Spartan-3A devices
and the Spartan-3A DSP devices available in the FG676
package. The arrows indicate the direction for easy
migration. For more details on the Spartan-3A DSP family
and pinouts, and additional differences in the FG676 pinout
for the XC3SD3400A device, see DS610.

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.
