7 Series FPGAs Overview
DS180 (v2.1) November 15, 2016
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
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.
•
•
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.
Summary of 7 Series FPGA Features
•
•
•
•

offering a special low-power mode, optimized for chip-to-chip
interfaces.
A user configurable analog interface (XADC), incorporating dual
12-bit 1MSPS analog-to-digital converters with on-chip thermal and
supply sensors.
DSP slices with 25 x 18 multiplier, 48-bit accumulator, and pre-adder
for high-performance filtering, including optimized symmetric
coefficient filtering.
•
•
•
•
Powerful clock management tiles (CMT), combining phase-locked
loop (PLL) and mixed-mode clock manager (MMCM) blocks for high
precision and low jitter.
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.
Low-cost, wire-bond, lidless flip-chip, and high signal integrity flip-
chip packaging offering easy migration between family members in
the same package. All packages available in Pb-free and selected
packages in Pb option.
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.
