5SGXA4

AlteraStratix V

The 5SGXA4 is a Stratix V FPGA from Altera, built on a 28 nm process. It provides 158,500 adaptive logic modules (ALMs) (420,000 logic elements (LEs)), 634,000 flip-flops, 37.1 Mb of block RAM and 256 variable-precision DSP blocks. It offers up to 696 user I/O pins and 36 GX transceivers at up to 14.1 Gb/s, with hard PCI Express Gen3 blocks. It is available in 3 packages, from the F1152 (HF35) (35 × 35 mm) to the F1517 (KF40) (40 × 40 mm). Designs are built with Altera Quartus Prime.
