The Virtex-7 H580T FPGA is the first 3D heterogeneous all programmable device, featuring up to eight 28 Gbps and 48 13.1 Gbps transceivers, making it the only single-chip solution to provide customers with the system integration to meet space, power and cost challenges of transitioning to 100G CFP2 optical modules.
As the world’s first 3D heterogeneous all programmable FPGA, the Virtex-7 H580T FPGA has clearly advanced the state-of-the-art in 3D IC technology. Like other Xilinx 3D IC devices, the Virtex-7 H580T FPGA addresses the challenges of interconnecting multiple FPGAs utilizing Xilinx’s Stacked Silicon Interconnect (SSI) technology, enabling high-bandwidth connectivity between multiple die and providing a 100x improvement in inter-die bandwidth per watt compared to multi-chip approaches. It also imposes much lower latency and consumes dramatically lower power than multi-FPGA or multi-chip module approaches, while enabling the integration of transceivers and on-chip resources within a single package. SSI technology leverages proven microbump technology combined with coarse pitch through-silicon vias (TSVs) on a passive (no transistors) 65nm silicon interposer to deliver high reliability interconnect without performance degradation on one FPGA device. This breakthrough technology provides the next level of advanced system integration for applications requiring high logic density and tremendous computational performance.
