Xilinx® 7 series FPGAs comprise three new FPGA families that address the complete range of system requirements, ranging from low cost, small form factor, cost-sensitive, high-volume applications to ultra high-end connectivity bandwidth, logic capacity, and signal processing capability for the most demanding high-performance applications. The 7 series devices are the programmable silicon foundation for Targeted Design Platforms that enable designers to focus on innovation from the outset of their development cycle. The 7 series FPGAs include:
• Artix™-7 Family: Optimized for lowest cost and power with small form-factor packaging for the highest volume applications.
• Kintex™-7 Family: Optimized for best price-performance with a 2X improvement compared to previous generation, enabling a new class of FPGAs.
• Virtex®-7 Family: Optimized for highest system performance and capacity with a 2X improvement in system performance. Highest capability devices enabled by stacked silicon interconnect (SSI) technology.
Built on a state-of-the-art, high-performance, low-power (HPL), 28 nm, high-k metal gate (HKMG) process technology, 7 series FPGAs enable an unparalleled increase in system performance with 2.9 Tb/s of I/O bandwidth, 2 million logic cell capacity, and 5.3 TMAC/s DSP, while consuming 50% less power than previous generation devices to offer a fully programmable alternative to ASSPs and ASICs. All 7 series devices share a unified fourthgeneration Advanced Silicon Modular Block (ASMBL™) column-based architecture that reduces system development and deployment time with simplified design portability.
