FG900: 900-lead Fine-pitch Ball Grid
Array
The 900-lead fine-pitch ball grid array package, FG900,
supports three different Spartan-3 devices, including the
XC3S2000, the XC3S4000, and the XC3S5000. The foot-
prints for the XC3S4000 and XC3S5000 are identical, as
shown in Table 34 and Figure 15. The XC3S2000, however,
has fewer I/O pins which consequently results in 68 uncon-
nected pins on the FG900 package, labeled as “N.C.” In
Table 34 and Figure 15, these unconnected pins are indi-
cated with a black diamond symbol (‹).
All the package pins appear in Table 34 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.
If there is a difference between the XC3S2000 pinout and
the pinout for the XC3S4000 and XC3S5000, then that dif-
ference is highlighted in Table 34. If the table entry is
shaded, then there is an unconnected pin on the XC3S2000
that maps to a user-I/O pin on the XC3S4000 and
XC3S5000.
