Pinout Descriptions
FG676: 676-ball Fine-pitch Ball Grid Array
The 676-ball fine-pitch ball grid array, FG676, supports the
XC3S1400A FPGA.
Table 78
by bank number and 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.
The XC3S1400A has 17 unconnected balls, indicated as
N.C. (No Connection) in
diamond character ( ) in
An electronic version of this package pinout table and
footprint diagram is available for download from the Xilinx
