10CX105

AlteraCyclone 10 GX

The 10CX105 is a Cyclone 10 GX FPGA from Altera, built on a 20 nm process. It provides 38,000 adaptive logic modules (ALMs) (104,000 logic elements (LEs)), about 76,000 LUT4 equivalents, 152,000 flip-flops, 7.5 Mb of block RAM and 125 variable-precision DSP blocks. It offers up to 284 user I/O pins and 12 XCVR transceivers at up to 12.5 Gb/s, with hard PCI Express Gen2 x4 blocks. It is available in 3 packages, from the U484 (19 × 19 mm) to the F780 (29 × 29 mm). Designs are built with Altera Quartus Prime.
