XC5VLX85-1FF676C - 82,944-Cell 65 nm FPGA | AMD
料号： XC5VLX85-1FF676C ✓ 量产中XC5VLX85-1FF676C 概述
An FPGA is a programmable-logic semiconductor whose physical array contains configurable logic blocks, programmable input/output resources, block RAM, and dedicated processing or clock resources. Within the product hierarchy, a field-programmable gate array is a programmable-logic device, an application-specific integrated circuit, and a semiconductor. Virtex-5 LX devices combine substantial logic density with high-speed connectivity for communications, industrial control, test equipment, signal processing, and embedded infrastructure applications.
Key characteristics include 82,944 total cells, 12,960 logic cells as identified for the associated Virtex-5 LX comparison entry, 65 nm CMOS technology, a 1 V supply, and a 676-ball FCBGA package. The -1 suffix identifies the selected performance grade, while -FF identifies the package and speed-related ordering form. The listed device is positioned for designs requiring substantial parallel processing capability without moving to a larger FPGA family.
The Virtex-5 architecture allows designers to implement multiple independent data paths, protocol bridges, control logic, and memory-intensive functions in parallel. Dedicated resources can accelerate designs involving serial connectivity, clocking, and embedded memory. Because FPGA routing and I/O resources are fixed after fabrication, design success depends on correct pin planning, timing closure, power budgeting, bank-voltage compatibility, and adequate implementation margins.
Typical applications include industrial networking equipment, telecom line cards, video and image processing, laboratory instrumentation, semiconductor test systems, storage controllers, embedded servers, and defense or aerospace platforms. The high logic count and large I/O count are particularly useful when a design combines multiple interfaces with parallel datapaths and requires deterministic hardware timing.
A critical design step is assigning every external interface to the correct I/O bank and checking the XC5VLX85-1FF676C package pinout before schematic capture. Power rails must also support the 1 V core requirement and the voltage tolerances of each I/O bank. Use the AMD or Xilinx datasheet pin-description table as the authoritative source for ball assignments.
This product summary combines the exact device identifiers with practical FPGA selection guidance, package-aware alternatives, and implementation cautions. It also separates the target grade from related speed or suffix variants, helping engineers determine whether a proposed substitution preserves both the physical footprint and the intended timing class.

典型应用
XC5VLX85-1FF676C 适用于 6 应用s: Industrial Networking, Telecommunications Line Cards, Video and Image Processing, Test and Measurement, Aerospace and Defense Systems, Industrial Control.
Industrial Networking
The XC5VLX85-1FF676C fits industrial Ethernet gateways, protocol converters, and packet-processing equipment because its Virtex-5 LX architecture provides 82,944 total cells while the 676-ball FCBGA exposes a large number of I/O resources. Parallel logic can implement multiple traffic paths, packet classifiers, queues, and control functions in one device. Its 1 V core supply suits a modern FPGA power tree, while the -1 grade provides a defined timing class for system budgets. Engineers should partition interfaces across compatible VCCO banks, preserve timing margin for simultaneous traffic processing, and verify the exact pin and temperature attributes before layout release.
推荐
Telecommunications Line Cards
A Virtex-5 LX device such as the XC5VLX85-1FF676C is appropriate for telecommunications line cards requiring parallel datapaths and extensive external connectivity. The 82,944-cell resource count supports aggregation, framing, queueing, and interface adaptation, while 65 nm CMOS and a 1 V core align with contemporary telecom board power designs. The 676-ball FCBGA provides a high pin count for parallel buses, memory interfaces, and high-speed serial transceivers. Power budgeting must cover core, auxiliary, and I/O supplies simultaneously, while design sign-off should include worst-case routing, bank-voltage rules, clock uncertainty, and thermal behavior.
推荐
Video and Image Processing
The XC5VLX85-1FF676C supports parallel video pipelines, image filtering, pixel classification, and frame-buffer control because the Virtex-5 LX fabric can implement wide datapaths with deterministic timing. Its 82,944 total cells provide more logic capacity than a small programmable logic device, and the 676-ball package allows substantial connection to external memory and sensors. A practical implementation should use dedicated block RAM where applicable, pipeline high-fanout control signals, and place memory and I/O interfaces according to timing and bank constraints. The 1 V core requirement must be separated from external interface voltages during power planning.
推荐
Test and Measurement
The XC5VLX85-1FF676C is useful in automated test equipment, signal analyzers, and instrumentation because its parallel programmable logic can coordinate timing, acquisition, stimulus, and data-processing functions. The large 676-ball package supports connections to converters, memory, clocks, and trigger systems, while the 82,944-cell Virtex-5 LX family supports deterministic hardware automation. Design the clocking tree first, isolate sensitive analog interfaces, and reserve I/O banks for the required logic levels. Timing closure must include instrument-grade calibration paths, trigger latency, and simultaneous acquisition performance rather than relying only on average logic utilization.
推荐
Aerospace and Defense Systems
The XC5VLX85-1FF676C can serve as the programmable core in aerospace, defense, and rugged embedded systems requiring deterministic parallel logic and extensive I/O. Virtex-5 LX fabric supports redundant control, data acquisition, signal conditioning, and communication functions in a single device, while the 676-ball FCBGA supports high-density board integration. Selection for a flight program must confirm the exact temperature grade, qualification status, radiation requirements, and procurement traceability because the commercial ordering code alone does not establish suitability. Engineers should also analyze single-event behavior, configuration reliability, power sequencing, and recovery behavior required by the system safety case.
推荐
Industrial Control
The XC5VLX85-1FF676C fits multi-axis machine controls, industrial controllers, and high-channel-count monitoring systems by combining programmable logic with a large pin count. Control loops, motion sequencing, safety interlocks, data acquisition, and communications can be implemented concurrently in deterministic hardware. Its 82,944-cell capacity supports larger control architectures than compact CPLDs, while the 1 V core supply simplifies integration with modern multi-rail power systems. Place safety-critical logic within the FPGA where appropriate, constrain timing explicitly, separate noisy I/O from sensitive paths, and verify thermal margins across the highest expected channel activity and ambient operating condition.

设计说明
Plan the 1 V core rail separately from the external I/O supplies. The core regulator must support the device's worst-case current, transient response, and permitted ripple, while each VCCO domain must match its connected signals. Decoupling should follow the manufacturer power-supply recommendations, with local high-frequency and bulk capacitance placed close to the relevant supply and ground balls. Configuration sequencing and power ramp limits must also be checked before enabling downstream circuitry.
Use the exact 676-ball FCBGA pin-description table throughout schematic capture and PCB layout. Assign each interface to a compatible voltage bank, preserve orientation and ball numbering, and avoid routing sensitive clocks or differential pairs through unnecessary vias. Because a 676-ball package requires fine-pitch escape routing, confirm the PCB design rules, pad stack, solder-mask definition, and assembly capability before committing the board outline.
Do not treat every XC5VLX85 ordering suffix as equivalent. The -1, -2, and -3 designations denote different speed classes, while final ordering characters can also identify grade-related attributes. A package-compatible alternative can still change timing closure, temperature range, qualification, or sourcing conditions. Review the manufacturer ordering guide, compare every ordering field, and rerun timing and power analysis before approving a substitution.
Define a complete clocking and reset strategy before routing interfaces. Use dedicated clock-capable inputs for high-fanout clock nets, constrain all generated clocks, and control reset distribution to avoid metastability or non-deterministic startup. For memory and high-speed serial interfaces, follow the device's bank and impedance guidance, preserve return paths, and validate eye margin and channel skew during system-level verification.
