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
ever, has fewer I/O pins which consequently results in 68
unconnected pins on the FG900 package, labeled as “N.C.”
In
indicated with a black diamond symbol ( ).
All the package pins appear in
bank number, 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.
If there is a difference between the XC3S2000 pinout and
the pinout for the XC3S4000 and XC3S5000, then that dif-
ference is highlighted in
shaded, then there is an unconnected pin on the XC3S2000
that maps to a user-I/O pin on the XC3S4000 and
XC3S5000.
An electronic version of this package pinout table and foot-
print diagram is available for download from the Xilinx web-
site at
