FG456: 456-lead Fine-pitch Ball Grid
Array
The 456-lead fine-pitch ball grid array package, FG456,
supports four different Spartan-3 devices, including the
XC3S400, the XC3S1000, the XC3S1500, and the
XC3S2000. The footprints for the XC3S1000, the
XC3S1500, and the XC3S2000 are identical, as shown in
Table 99
I/O pins which consequently results in 69 unconnected pins
on the FG456 package, labeled as “N.C.” In

black diamond symbol ( ).
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.
If there is a difference between the XC3S400 pinout and the
pinout for the XC3S1000, the XC3S1500, or the XC3S2000,
then that difference is highlighted in
entry is shaded grey, then there is an unconnected pin on
the XC3S400 that maps to a user-I/O pin on the XC3S1000,
XC3S1500, and XC3S2000. If the table entry is shaded tan,
then the unconnected pin on the XC3S400 maps to a
VREF-type pin on the XC3S1000, the XC3S1500, or the
XC3S2000. If the other VREF pins in the bank all connect to
a voltage reference to support a special I/O standard, then
also connect the N.C. pin on the XC3S400 to the same
VREF voltage. This provides maximum flexibility as you
could potentially migrate a design from the XC3S400 device
to an XC3S1000, an XC3S1500, or an XC3S2000 FPGA
without changing the printed circuit board.

print diagram is available for download from the Xilinx web-
