FG320: 320-lead Fine-pitch Ball Grid
Array
The 320-lead fine-pitch ball grid array package, FG320,
supports three different Spartan-3 devices, including the
XC3S400, the XC3S1000, and the XC3S1500. The footprint
for all three devices is identical, as shown in
Figure
The FG320 package is an 18 x 18 array of solder balls
minus the four center balls.
All the package pins appear in
bank number, then by pin name. Pairs of pins that form a dif-
ferential 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.
An electronic version of this package pinout table and foot-
print diagram is available for download from the Xilinx web-
site at
