Notes:
1. Some VREF pins are on INPUT pins. See pinout tables for details.
2. All devices have 24 possible global clock and right- and left-half side clock inputs. The right-half and bottom-edge clock pins have shared
functionality in some FPGA configuration modes. Consequently, some clock pins are counted in the DUAL column. 4 GCLK pins, including
2 DUAL pins, are on INPUT pins.
Electronic versions of the package pinout tables and foot-
prints are available for download from the Xilinx website.
Download the files from the following location: Using a
spreadsheet program, the data can be sorted and reformat-
ted according to any specific needs. Similarly, the
ASCII-text file is easily parsed by most scripting programs.
