Spartan-3 FPGA Family: Pinout Descriptions
FG676: 676-lead Fine-pitch Ball Grid
Array
The 676-lead fine-pitch ball grid array package, FG676,
supports five different Spartan-3 devices, including the
XC3S1000, XC3S1500, XC3S2000, XC3S4000, and
XC3S5000. All five have nearly identical footprints but are
slightly different, primarily due to unconnected pins on the
XC3S1000 and XC3S1500. For example, because the
XC3S1000 has fewer I/O pins, this device has 98 uncon-
nected pins on the FG676 package, labeled as “N.C.” In
Table 102
cated with a black diamond symbol ( ). The XC3S1500,
however, has only two unconnected pins, also labeled
“N.C.” in the pinout table but indicated with a black square
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 XC3S1000, XC3S1500,
XC3S2000, XC3S4000, and XC3S5000 pinouts, then that
difference is highlighted in
shaded grey, then there is an unconnected pin on either the
XC3S1000 or XC3S1500 that maps to a user-I/O pin on the
XC3S2000, XC3S4000, and XC3S5000. If the table entry is
shaded tan, then the unconnected pin on either the
XC3S1000 or XC3S1500 maps to a VREF-type pin on the
XC3S2000, XC3S4000, and XC3S5000. 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
XC3S1000 or XC3S1500 to the same VREF voltage. This
provides maximum flexibility as you could potentially
migrate a design from the XC3S1000 through to the
XC3S5000 FPGA without changing the printed circuit
board.
