Ti165

EfinixTitanium

The Ti165 is a Titanium SoC FPGA from Efinix, built on a 16 nm process. It provides 159,610 LUT4 look-up tables (162,800 logic elements (LEs)), 159,610 flip-flops, 12.1 Mb of block RAM and 590 DSP blocks. Its processing system includes four RISC-V RV32 cores. The programmable logic offers up to 337 user I/O pins and 16 SERDES transceivers at up to 16 Gb/s, with hard PCI Express Gen4 x4 blocks. It is available in 5 packages, from the FBGA484 (18 × 18 mm) to the FBGA1156 (35 × 35 mm). Designs are built with Efinix Efinity.
