Tz75
EfinixTopazThe Tz75 is a Topaz SoC FPGA from Efinix, built on a 16 nm process. It provides 80,770 LUT4 look-up tables (75,520 logic elements (LEs)), 80,770 flip-flops, 5.3 Mb of block RAM and 264 DSP blocks. Its processing system includes four RISC-V cores. The programmable logic offers up to 223 user I/O pins and 8 SERDES transceivers at up to 12.5 Gb/s, with hard PCI Express Gen3 x4 blocks. It is available in 4 packages, from the FBGA441 (11 × 11 mm) to the FBGA676 (22 × 22 mm). Designs are built with Efinix Efinity.
