FG400: 400-ball Fine-pitch Ball Grid Array
The 400-ball fine-pitch ball grid array, FG400, supports two
different Spartan-3E FPGAs, including the XC3S1200E and
the XC3S1600E. Both devices share a common footprint for
this package as shown in Table 152 and Figure 88.

I/O
Table 152 lists all the FG400 package pins. They are sorted
by bank number and then by pin name. Pairs of pins that
form a differential I/O pair appear together in the table. The
table also shows the pin number for each pin and the pin
type, as defined earlier.
