XC7S6
AMDSpartan-7The XC7S6 is a Spartan-7 FPGA from AMD, built on a 28 nm process. It provides 3,752 LUT6 look-up tables (6,000 logic cells), about 6,003 LUT4 equivalents, 7,500 flip-flops, 0.2 Mb of block RAM and 10 DSP slices. It offers up to 100 user I/O pins. It is available in 3 packages, from the CPGA196 (8 × 8 mm) to the FTGB196 (15 × 15 mm). Temperature grades: commercial, industrial, expanded. Designs are built with AMD Vivado.
