FT256: 256-lead Fine-pitch Thin Ball
Grid Array
The 256-lead fine-pitch thin ball grid array package, FT256,
supports three different Spartan-3 devices, including the
XC3S200, the XC3S400, and the XC3S1000. The footprints
for all three devices are identical, as shown in
Figure
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.
An electronic version of this package pinout table and foot-
print diagram is available for download from the Xilinx web-
site at
