Spartan-3E FPGA Family: Pinout Descriptions
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 151 and Figure 87.

Table 151 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.
