5CSXC4

AlteraCyclone VSoC

The 5CSXC4 is a Cyclone V SoC FPGA from Altera, built on a 28 nm process. It provides 15,880 adaptive logic modules (ALMs) (40,000 logic elements (LEs)), about 31,760 LUT4 equivalents, 60,376 flip-flops, 2.6 Mb of block RAM and 84 variable-precision DSP blocks. Its processing system includes two Arm Cortex-A9 cores. The programmable logic offers up to 145 user I/O pins and 6 XCVR transceivers at up to 3.125 Gb/s, with hard PCI Express Gen1 blocks. It comes in a single package, the U672 (23 × 23 mm). Designs are built with Altera Quartus Prime.
