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 I/O performance. Available in low-cost, very small form-factor packaging for smallest PCB footprint.
• Artix®-7 Family: Optimized for low power applications requiring serial transceivers and high DSP and logic throughput. Provides the lowest total bill of materials cost for
high-throughput, cost-sensitive 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.

• Designed for high performance and lowest power with 28 nm, HKMG, HPL process, 1.0V core voltage process technology and
0.9V core voltage option for even lower power.
• Integrated block for PCI Express® (PCIe), for up to x8 Gen3 Endpoint and Root Port designs.
• Wide variety of configuration options, including support for commodity memories, 256-bit AES encryption with HMAC/SHA-256
authentication, and built-in SEU detection and correction.
• Advanced high-performance FPGA logic based on real 6-input lookup table (LUT) technology configurable as distributed memory.
• 36 Kb dual-port block RAM with built-in FIFO logic for on-chip data
buffering.
• DSP slices with 25 x 18 multiplier, 48-bit accumulator, and pre-adder for high-performance filtering, including optimized symmetric coefficient filtering.
