FG484: 484-ball Fine-pitch Ball Grid Array
The 484-ball fine-pitch ball grid array, FG484, supports both
the XC3S700A and the XC3S1400A FPGAs. There are
three pinout differences, as described in
Table 74
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.
The shaded rows indicate pinout differences between the
XC3S700A and the XC3S1400A FPGAs. The XC3S700A
has three unconnected balls, indicated as N.C. (No
Connection) in
character ( ) in
An electronic version of this package pinout table and
footprint diagram is available for download from the Xilinx
website at
