FG676: 676-Ball Fine-Pitch Ball Grid Array
The 676-ball fine-pitch ball grid array, FG676, supports both the XC3SD1800A and the XC3SD3400A FPGAs. There are
multiple pinout differences between the two devices. For a list of differences and migration advice, see the
Footprint
Migration Differences
section.
XC3SD1800A FPGA
Table 66
lists all the FG676 package pins for the XC3SD1800A FPGA. They are sorted 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.
Pinout Table
Note:
The grayed boxes denote a difference between the XC3SD1800A and the XC3SD3400A devices.
