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 Table 25 and
Figure 12.
The FG320 package is an 18 x 18 array of solder balls
minus the four center balls.
All the package pins appear in Table 25 and are sorted by
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.
