SX 2500
AlteraStratix 10 GX/SXSoCThe SX 2500 is a Stratix 10 GX/SX SoC FPGA from Altera, built on a 14 nm process. It provides 821,150 adaptive logic modules (ALMs) (2,422,000 logic elements (LEs)), about 1,642,300 LUT4 equivalents, 195 Mb of block RAM and 5,011 variable-precision DSP blocks. Its processing system includes four Arm Cortex-A53 cores running at up to 1.5 GHz. The programmable logic offers up to 1,160 user I/O pins and 96 XCVR/XCVR transceivers at up to 28.3 Gb/s, with hard PCI Express Gen3 x16 blocks. It is available in 3 packages, from the F1760 (42.5 × 42.5 mm) to the F2912 (55 × 55 mm). Designs are built with Altera Quartus Prime.
