5CGXC4

AlteraCyclone VSoC

The 5CGXC4 is a Cyclone V FPGA from Altera, built on a 28 nm process. It provides 18,868 adaptive logic modules (ALMs) (50,000 logic elements (LEs)), about 37,736 LUT4 equivalents, 75,440 flip-flops, 2.4 Mb of block RAM and 70 variable-precision DSP blocks. It offers up to 336 user I/O pins and 6 XCVR transceivers at up to 3.125 Gb/s, with hard PCI Express Gen1 blocks. It is available in 5 packages, from the M301 (11 × 11 mm) to the F672 (27 × 27 mm). Designs are built with Altera Quartus Prime.
