7 Series FPGAs Data Sheet: Overview
DS180 (v2.6) February 27, 2018 Product Specification
General Description
Xilinx 7 series FPGAs comprise four 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 FPGAs include:
Spartan-7 Family: Optimized for low cost, lowest power, and high Kintex-7 Family: Optimized for best price-performance with a 2X
I/O performance. Available in low-cost, very small form-factor improvement compared to previous generation, enabling a new class
packaging for smallest PCB footprint. of FPGAs.
Artix-7 Family: Optimized for low power applications requiring serial Virtex-7 Family: Optimized for highest system performance and
transceivers and high DSP and logic throughput. Provides the lowest capacity with a 2X improvement in system performance. Highest
total bill of materials cost for high-throughput, cost-sensitive capability devices enabled by stacked silicon interconnect (SSI)
applications. 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.
