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 scalable, optimized fourth-generation Advanced Silicon Modular Block (ASMBL™) column-based architecture that reduces system development and deployment time with simplified design portability.

Xilinx 7系列FPGA主要特性:

• 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.

• High-performance SelectIO™ technology with support for DDR3 interfaces up to 1,866 Mb/s.

• High-speed serial connectivity with built-in multi-gigabit transceivers from 600 Mb/s to maximum rates of 6.6 Gb/s up to 28.05 Gb/s, 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 flipchip 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.

Virtex®-7 FPGAs are available in -3, -2, -1, and -2L speed grades, with -3 having the highest performance. The -2L devices can operate at either of two VCCINT voltages, 0.9V and 1.0V and are screened for lower maximum static power.

When operated at VCCINT = 1.0V, the speed specification of a -2L device is the same as the -2 speed grade. When operated at VCCINT = 0.9V, the -2L performance and static and dynamic power is reduced. The -2G speed grade is available in devices utilizing Stacked Silicon Interconnect Technology. The -2G speed grade supports 12.5 Gb/s GTX,13.1 Gb/s GTH, and 28.05 Gb/s GTZ transceivers as well as the standard -2 speed grade specifications.

Virtex-7 FPGA DC and AC characteristics are specified for commercial, extended, and industrial temperature ranges.

Except the operating temperature range or unless otherwise noted, all the DC and AC electrical parameters are the same for a particular speed grade (that is, the timing characteristics of a -1 speed grade industrial device are the same as for a -1 speed grade commercial device). However, only selected speed grades and/or devices are available in
each temperature range.

All supply voltage and junction temperature specifications are representative of worst-case conditions. The parameters included are common to popular designs and typical applications.
