A3C 135

AlteraAgilex 3

The A3C 135 is an Agilex 3 FPGA from Altera, built on the Intel 7 process. It provides 45,800 adaptive logic modules (ALMs) (135,110 logic elements (LEs)), about 91,600 LUT4 equivalents, 183,200 flip-flops, 6.9 Mb of block RAM and 184 variable-precision DSP blocks. Versions with the optional hard processor system include two Arm Cortex-A55 cores. The programmable logic offers up to 392 user I/O pins and 4 XCVR transceivers at up to 12.5 Gb/s, with hard PCI Express Gen3 x4 blocks. It is available in 3 packages, from the M16A (16 × 16 mm) to the B23C (23 × 23 mm). Designs are built with Altera Quartus Prime.
