Core Architecture Features of the Virtex-7 XC7VX980T

Advanced 6-Input LUT Fabric

The XC7VX980T-L2FFG1926E is built around Xilinx’s proven 6-input look-up table (LUT) architecture. Each LUT can be configured as a logic element or as distributed RAM/shift register, enabling flexible, high-density logic implementation without sacrificing routing resources.

36 Kb Dual-Port Block RAM with FIFO

On-chip memory is organized into 36 Kb dual-port block RAM tiles, each featuring built-in FIFO logic. This simplifies data buffering architectures significantly, reducing the need for external memory controllers in many pipelined designs.

High-Performance SelectIO Technology

The SelectIO interface supports DDR3 data rates up to 1,866 Mb/s, making the XC7VX980T-L2FFG1926E well-suited for memory-intensive applications such as image processing, financial computing, and radar signal processing.

Multi-Gigabit GTX Transceivers

The device integrates up to 80 GTX transceivers operating from 600 Mb/s to 11.3 Gb/s. A special low-power mode is available, optimized for chip-to-chip interfaces where signal integrity and power efficiency are paramount.

PCIe Gen3 Hard IP Block

An integrated PCIe block supports up to x8 Gen3, enabling seamless connection to high-speed CPU and memory subsystems without consuming soft logic resources. This is particularly valuable in FPGA-accelerated computing and network appliance designs.

Frequently Asked Questions (FAQ)

What does the “L2” speed grade mean in XC7VX980T-L2FFG1926E?

The “L” prefix in the speed grade designation indicates a low-power variant. The -L2 grade is optimized for reduced static power consumption versus the standard commercial -2 grade, while maintaining the same performance characteristics. This makes it suitable for applications where thermal management is a design constraint.

What is the maximum transceiver data rate for XC7VX980T-L2FFG1926E?

The GTX transceivers in the XC7VX980T support data rates from 600 Mb/s up to 11.3 Gb/s per lane, with a special low-power mode available for chip-to-chip interfaces.

Is the XC7VX980T-L2FFG1926E suitable for industrial and defense applications?

Yes. The “E” temperature suffix confirms an extended temperature range of –40°C to +100°C, making it suitable for industrial, defense, and aerospace deployments where commercial-grade temperature ratings are insufficient.

How many user I/Os does the XC7VX980T-L2FFG1926E have?

The FFG1926 package configuration provides 720 user I/O pins. If your design requires more I/Os, the FFG1930 package variant of the same device offers 900 user I/Os.

What PCIe generation does the XC7VX980T support?

The device integrates a hard PCIe IP block supporting PCIe Gen3 x8 for both Endpoint and Root Port designs, enabling high-bandwidth connections to host processors and other system components.
