XCSU45P

AMDSpartan UltraScale+

The XCSU45P is a Spartan UltraScale+ FPGA from AMD, built on a 16 nm process. It provides 24,000 LUT6 look-up tables (53,000 system logic cells), about 38,400 LUT4 equivalents, 48,000 flip-flops, 2.5 Mb of block RAM and 96 DSP slices. It offers up to 262 user I/O pins and 4 GTH transceivers at up to 16.3 Gb/s, with hard PCI Express Gen4 x4 blocks. It is available in 3 packages, from the CMVE529 (12 × 12 mm) to the SBVB625 (21 × 21 mm). Temperature grades: extended, industrial. Designs are built with AMD Vivado.
