The XC6SLX4-2TQG144C is a Spartan?-3AN FPGA, available in various speed grades, with -3 having the highest performance. The timing characteristics of the commercial (XC) -2 speed grade industrial device are the same as for a -2 speed grade commercial device. The -2Q speed grade is exclusively for the expanded (Q) temperature range. The timing characteristics are equivalent to those shown for the -2 speed grades for the automotive and defence-grade devices.
