A field-programmable gate array is a semiconductor device whose digital logic, interconnect, and I/O behavior are configured after manufacture. The FPGA category sits above programmable logic devices and forms part of the broader semiconductor and embedded-processing ecosystem. Compared with a fixed-function application-specific integrated circuit, an FPGA supports design changes, parallel processing, custom interfaces, and hardware acceleration without requiring a new ASIC fabrication run. The Virtex-5 LX family uses AMD's second-generation ASMBL column-based architecture.
The XC5VLX85-2FF676I combines 3,538,944 logic cells, 82,944 register bits, and 440 I/O in one high-pin-count package. These figures make the device suitable for systems requiring considerable parallel logic, multiple high-speed interfaces, substantial data movement, or adaptable control paths. The -2 speed designation identifies a specific performance grade, while the industrial temperature designation supports designs intended to operate across an extended environmental range when the complete system and board-level requirements are also satisfied.
The large 676-ball FCBGA footprint exposes substantially more device connections than a typical leaded FPGA package. That interface density can support wide parallel buses, multiple I/O standards, dedicated memory interfaces, clocks, and high-speed differential pairs. Because package escape routing, power delivery, and ball-assignment constraints become more demanding at this density, the device should be designed using the manufacturer’s pinout, package information, and board-design guidance rather than inferred from a generic BGA symbol.
Typical uses include industrial control and automation, communications infrastructure, test and measurement equipment, embedded instrumentation, video processing, and high-throughput data-acquisition systems. Its 440 available I/O can accommodate multiple external interfaces, while the 85K-scale logic fabric can implement parallel algorithms, protocol engines, control logic, and signal-processing pipelines. Industrial temperature grading is particularly relevant to equipment that must operate reliably beyond typical consumer-environment limits.
The main design consideration is that a 676-ball FPGA requires disciplined power-plane segmentation, decoupling, ball-grid layout work, and careful high-speed routing. Designers should preserve the pin and bank functions required by the design, validate every I/O standard against the selected bank, and use the manufacturer’s recommended configuration and power-sequencing procedures. Migration to another device should not be treated as automatic even when logic resources and package names appear similar.
This product page organizes the verified device identity, package details, commercial inquiry path, comparison points, and engineering guidance around the XC5VLX85-2FF676I. It also distinguishes true package-compatible family options from broader FPGA redesign alternatives, helping teams evaluate replacement risk before committing to a new PCB or bitstream.

Talaan ng Disenyo
Implement the Virtex-5 recommended power architecture with separate supply rails where required by the device configuration. Place bulk and high-frequency decoupling capacitors close to their assigned package balls, preserve the recommended power-plane connectivity, and control sequencing across supply groups. Do not estimate rail requirements from generic FPGA experience alone; use the exact device power table and board-design guide for XC5VLX85-2FF676I.
Plan the 676-ball FCBGA escape routing and complete ball-assignment check before schematic release. Match pin functions to the exact ordering code and package revision, retain clock-capable and voltage-reference assignments, and route high-speed differential pairs with continuous reference planes. A package name match does not prove ball-for-ball compatibility between ordering-code variants.
Use the manufacturer’s I/O-standard and bank rules to select voltage, slew, and drive settings. Keep clocks on appropriate clock-capable pins, route source-synchronous interfaces with matched data and strobe topology, and include series termination where the I/O standard and board environment require it. Validate edge quality and timing at the -2 speed grade rather than relying only on functional simulation.
Do not treat the XC5VLX85, XC5VLX110, or different speed and temperature suffixes as unconditional substitutions. The XC5VLX85-3FF676C changes both speed and thermal grade, while XC5VLX110 changes device resources. Confirm lifecycle requirements, I/O assignments, timing, power, configuration behavior, and qualification, then rebuild and rerun all timing and hardware tests before production use.
