XC3S5000-5FG676C

XC3S5000-5FG676C - 5M Gate Spartan-3 FPGA | AMD/Xilinx

The AMD/Xilinx XC3S5000-5FG676C is a Spartan-3 field-programmable gate array with 5 million system gates, 74,880 logic cells, and a maximum stated operating frequency of 725 MHz. The device uses 90 nm process technology, operates from a 1.2 V core supply, and is packaged in a 676-pin fine-pitch ball grid array. The commercial-grade C suffix corresponds to an operating-temperature range of 0°C to 85°C according to the published product information. A field-programmable gate array, or FPGA, is a programmable semiconductor containing configurable logic blocks, programmable interconnect, input/output resources, and embedded memory. FPGAs belong to the programmable-logic hierarchy, combining digital design flexibility with high-density parallel processing. The Spartan-3 family targets cost-sensitive embedded systems where designers require substantial logic capacity, multiple I/O, and field-updatable configurations without changing the assembled PCB. The XC3S5000-5FG676C provides 74,880 logic cells, 5 million system gates, and a 725 MHz stated maximum frequency. Its 676-ball package supports a high pin count compared with smaller FPGA packages, making it suitable for designs requiring extensive parallel interfaces. The 90 nm fabrication process and 1.2 V core supply are important for system planning because power dissipation, configuration requirements, and external I/O voltage levels must be evaluated as a complete power architecture. Its programmable logic can implement control logic, serial and parallel interfaces, protocol bridges, state machines, signal conditioning, and embedded datapaths. Designs can combine multiple fixed-function functions in one device, reducing component count and allowing configuration changes during product maintenance. Because an FPGA is programmed after fabrication, its internal architecture supports field updates, debugging, and product differentiation without physically replacing the IC. Typical uses include industrial automation, communications equipment, test and measurement systems, embedded control, video processing, and high-density interface aggregation. The large 676-ball package is especially relevant when a design requires many I/O sites or a substantial connector count. A smaller Spartan-3 device may be preferable when the system does not require the XC3S5000's 74,880 logic cells or high pin count. When designing a board around this FPGA, use the manufacturer datasheet and package documentation to verify every ball assignment, configuration interface, power rail, decoupling requirement, and I/O standard. The 1.2 V core supply and 725 MHz frequency figure describe the device itself, but actual clocking, performance, and power depend on the selected I/O standards, logic utilization, speed grade, configuration method, PCB construction, and thermal design. This page combines the published XC3S5000-5FG676C specifications, sourcing information, application guidance, and verified same-family alternatives into an engineering-focused reference for FPGA designers and component selectors.

XC3S500E-4PQ208I

XC3S500E-4PQ208I - Spartan-3E FPGA 208-BFQFP | AMD

The AMD XC3S500E-4PQ208I is a Spartan-3E field-programmable gate array in a 208-BFQFP package. It provides 500,000 system gates, 10,476 configurable logic cells, 158 user I/O, and a 4 speed grade. The industrial-temperature suffix I supports operation from 0°C to 85°C. These characteristics make the device suitable for cost-sensitive embedded control, communications, industrial automation, and consumer-equipment designs requiring programmable logic and substantial parallel I/O. A field-programmable gate array is a semiconductor whose digital logic and connectivity are configured after manufacture. Within the product hierarchy, an FPGA is a programmable logic device and a semiconductor. The Spartan-3E family combines configurable logic blocks, programmable I/O, block RAM, dedicated arithmetic resources, and clock-management functions on one device. This integration allows a board to implement control logic, protocol handling, data acquisition, and peripheral interfaces without relying on a collection of discrete logic ICs. The XC3S500E-4PQ208I includes 10,476 configurable logic cells and 158 user I/O, providing high connectivity for parallel buses, industrial interfaces, and embedded processor peripherals. Its 4 speed grade is intended for designs operating below the 5 speed-grade ceiling. The 208-pin surface-mount package supports higher I/O density than the smaller 100-pin and 132-pin alternatives in the same family, while the 28 mm by 28 mm footprint requires careful PCB routing and thermal analysis. Spartan-3E devices use configurable logic blocks and distributed or block memory resources to implement digital systems whose requirements may evolve after hardware design begins. The XC3S500E family also supports dedicated multipliers, block RAM, and clock functions for designs requiring arithmetic, local storage, or multiple clock domains. Configuration, pin constraints, timing, and power behavior should be evaluated with the current AMD FPGA design tools before schematic sign-off. Typical applications include industrial automation controllers, telecommunications line-card logic, data-acquisition systems, embedded control platforms, and instrumentation. In these systems, the high I/O count can connect external memories, transceivers, sensors, and parallel processors, while programmable logic allows firmware-independent field updates. Designers should confirm timing closure for the intended clock frequency and verify that the selected I/O standards suit each interface. PCB implementation requires a stable multilayer structure, continuous ground-plane coverage, and careful decoupling around every supply pin. The 208-BFQFP lead pitch requires a qualified assembly process, and exposed programming and configuration signals must be routed away from high-speed nodes. A finished design should also include a defined startup or configuration strategy so the FPGA operates deterministically after power application. This page combines package, logic-resource, temperature, and application guidance with practical drop-in replacement analysis. It also organizes pin, procurement, and selection questions around the device's industrial Spartan-3E positioning, helping engineers compare footprint compatibility, temperature grade, speed grade, and lifecycle needs before releasing a PCB.

XC3S500E-4PQG208C - 500K Gate Spartan-3E FPGA | AMD
XC3S500E-4PQG208C

XC3S500E-4PQG208C - 500K Gate Spartan-3E FPGA | AMD

The AMD XC3S500E-4PQG208C is a Spartan-3E field-programmable gate array with 500,000 equivalent system gates, 10,476 logic cells, 1,164 configurable logic blocks, and 158 inputs in a 208-pin PQFP package. The device uses a 1.2 V supply and is identified by the provided data as supporting up to 572 MHz. It is a surface-mount programmable logic device for embedded control, signal processing, interface bridging, and parallel data acquisition systems. A field-programmable gate array, or FPGA, is a programmable digital logic device whose configurable logic and interconnect resources can be programmed after manufacture. FPGAs sit above fixed-function logic devices and programmable gate arrays in the digital-semiconductor hierarchy: a design can use programmable logic to implement counters, state machines, ALUs, control logic, and interface circuits without requiring a custom ASIC. Spartan-3E devices provide a practical balance between logic capacity, device cost, and design flexibility for embedded systems. The verified specifications identify the XC3S500E-4PQG208C as a 500K-gate Spartan-3E FPGA with 10,476 logic cells, 1,164 CLBs, 158 inputs, and a maximum clock frequency of 572 MHz. The 208-PQFP package provides a leaded, inspectable footprint for conventional surface-mount assembly. The C suffix and the verified distributor listings identify the exact commercial ordering code; the supplied sources do not provide a complete temperature-grade or lifecycle classification. This FPGA is suitable for control and sequencing logic where multiple parallel channels, counters, timers, and state machines must be implemented in one device. Its logic capacity can also support moderate data paths and protocol interfaces. The 572 MHz maximum clock figure should be treated as a device-level headline value; actual achievable clock rates depend on the selected I/O standard, timing constraints, routing, logic depth, and the external memory or transceiver interface. Typical applications include industrial automation, test-and-measurement front ends, communications adapters, embedded control systems, and signal-processing support. The package is particularly useful where a leaded package is preferred over a fine-pitch BGA and where the design requires a moderate number of I/O connections. Designers should verify board pinout, configuration requirements, power sequencing, I/O standards, and signal-integrity margins against the manufacturer datasheet before layout release. The principal design consideration is package-related routing and signal integrity. A 208-pin PQFP requires adequate copper clearances and controlled escape routing, especially for high-speed clock and interface nets. Configuration storage, bank supply voltages, decoupling, and pinout details must be implemented exactly as specified in the AMD Spartan-3E documentation. This page combines verified distributor and AMD documentation references with application guidance, lifecycle caveats, package-specific design notes, and explicitly qualified replacement analysis for engineers evaluating the XC3S500E-4PQG208C.

AMD XC3S50A-4FT256C is a Spartan-3A field-programmable gate array with approximately 50,000 logic gates, 144 user I/O, and a 256-pin fine-pitch ball grid array package. The device operates from a 1.14 V to 1.26 V core-voltage range and is identified as a last-time-buy product. Its 4 speed grade supports cost-sensitive programmable logic applications where a compact, nonvolatile FPGA implementation is preferable to a fixed-function logic device. A field-programmable gate array is a semiconductor whose digital logic, interconnect, and input/output functions are configured after manufacture. Within the FPGA hierarchy, the Spartan-3A family belongs to the low-to-medium-density programmable-logic segment. The XC3S50A combines approximately 50,000 gates, 144 I/O, and a 256-ball FTBGA package in a surface-mount device suitable for compact embedded control, interface, data-capture, and industrial automation equipment. The available specifications identify 144 user I/O, a 1.14 V to 1.26 V core-voltage range, and an approximate gate count of 50,000. These resources support parallel control logic, protocol interfaces, glue logic, and modest embedded processing systems. The C suffix identifies the commercial product variant, while the -4 portion denotes the device speed grade. Detailed RAM, clock, configuration, and I/O standards were not present in the supplied verified data and must be confirmed from the AMD Spartan-3A family datasheet before design release. The XC3S50A-4FT256C is supplied in tray packaging according to the available product listing. Its 256-pin fine-pitch BGA format creates a compact land pattern but requires careful PCB layout, via-in-pad or via-under-bump considerations, and assembly processes capable of handling closely spaced balls. Signal-integrity, power-delivery, thermal, and exact package-dimension guidance should be taken directly from the AMD DS529 family document and the device pinout information. Typical uses include industrial automation controllers, instrumentation, embedded communications, consumer interfaces, and cost-sensitive control systems. Because the part is listed as last time buy, new production should include lifecycle review, planned end-of-life inventory, and a qualified second source. Lead time is listed as 12 weeks, making procurement planning essential for designs that cannot tolerate a supply interruption. Design engineers should verify the exact pinout, supported I/O standards, configuration interface, memory resources, and power requirements in the AMD Spartan-3A family datasheet before layout release. This page consolidates the supplied distributor data, lifecycle information, pricing references, drop-in family variants, and practical implementation considerations to support engineering selection.

XC3S50A-4FT256I - Spartan-3A 256-LBGA FPGA | AMD
XC3S50A-4FT256I

XC3S50A-4FT256I - Spartan-3A 256-LBGA FPGA | AMD

The AMD XC3S50A-4FT256I is a Spartan-3A field-programmable gate array in a 256-ball, square, surface-mount LBGA package. The -4 suffix identifies the device speed grade, the FT code identifies the 256-ball package configuration, and the final I indicates industrial-temperature grading. Verified distributor information identifies the device as an FPGA with 144 I/O, 55,296 gates, and 1,584 logic cells. It is positioned for designs that require programmable digital logic, parallel interfaces, embedded control, and compact system integration. A field-programmable gate array is a semiconductor whose digital configuration is defined after fabrication. The FPGA category sits above programmable logic devices and below configurable digital system components, combining configurable logic blocks, programmable I/O, and dedicated resources in one integrated circuit. This hierarchy allows engineers to implement control, communications, data acquisition, signal processing, and interface logic on hardware that can be revised without changing the printed circuit board. The Spartan-3A family provides configurable logic blocks containing lookup tables and flip-flops, along with programmable general-purpose I/O and dedicated multiplier and accumulator resources in DSP48A slices. Those DSP48A resources are useful for multiply-accumulate operations, while the 144-I/O configuration supports systems with substantial external bus and control connectivity. The exact switching, timing, configuration-memory, and electrical limits must be confirmed in the AMD DS529 Spartan-3A family data sheet before a design is released. The XC3S50A-4FT256I is differentiated by its combination of the -4 performance grade, industrial-temperature grading, and 256-ball LBGA package. The industrial marking makes it more appropriate for temperature-controlled factory, telecom, and test equipment than a commercial-temperature alternative. The compact 17 x 17 mm package also supports dense board layouts, although its 256-ball geometry requires careful inspection and assembly planning. Typical applications include industrial automation, telecommunications, embedded instrumentation, data-acquisition systems, and compact control platforms. In these systems, the FPGA can consolidate parallel interface logic, perform protocol conversion, coordinate control sequencing, or implement DSP pipelines. Pairing it with an external data converter, communications transceiver, and nonvolatile configuration storage can produce a complete embedded processing subsystem. Designers should treat the 256-LBGA footprint as a demanding assembly constraint. The board should use an appropriate ball pitch and copper-compatible surface finish, while assembly planning must account for inspection, cleaning, placement, and solder-joint verification. Power rails, configuration sequencing, decoupling, clocking, and I/O standards should be designed from the complete AMD datasheet rather than inferred solely from the ordering code. This page combines verified distributor specifications, package data, and the AMD DS529 family reference with practical considerations that are not visible in a basic distributor listing. It also separates documented facts from parameters that still require schematic-level and board-level verification, helping engineers evaluate the XC3S50A-4FT256I for industrial FPGA designs without relying on assumptions.

XC3S50A-4FTG256C

XC3S50A-4FTG256C - 50K Spartan-3A FPGA | AMD

The AMD XC3S50A-4FTG256C is a Spartan-3A field-programmable gate array with 50K logic gates, 55,296 logic cells, 1,584 configurable slices, and 144 user I/O in a 256-ball FTBGA package. It is manufactured on 90 nm CMOS technology, operates from a 1.2 V core supply, and is specified at a nominal 667 MHz performance point. The -4 designation identifies its speed grade, while the final C suffix identifies the commercial temperature grade. A field-programmable gate array is a semiconductor whose digital logic, interconnect, and I/O functions are configured after fabrication. An FPGA belongs to the programmable-logic device hierarchy, alongside CPLDs, and provides parallel hardware implementation of control, signal-processing, communications, and data-acquisition functions. The Spartan-3A family combines moderate logic density with a large I/O count in a cost-conscious architecture for embedded control and industrial equipment. The XC3S50A-4FTG256C provides 144 user I/O, giving it substantial connectivity for parallel buses, control signals, and external interfaces. Its 1,584 slices divide the 55,296 logic cells into parallel programmable resources for combinational and sequential logic. The 50K-gate description provides a relative scale for system architects, while the 667 MHz figure establishes the device's timing-performance class for clocked designs. The 256-ball FTBGA package supports compact PCB integration but requires careful escape routing, via-in-pad considerations, and thermal design. A 90 nm fabrication process and 1.2 V core supply place this device in an established low-power FPGA generation. Designers should use the AMD DS529 family data sheet for package dimensions, pin definitions, configuration requirements, bank voltage rules, and supported I/O standards. Typical uses include industrial control systems, instrument interfaces, digital signal-processing front ends, communications equipment, and embedded test systems. Its combination of 144 I/O and 1,584 slices is useful when an application needs many parallel external connections or moderate logic parallelism rather than the density of a larger FPGA. Configuration storage, clocking, power sequencing, and JTAG programming remain essential board-level functions. When replacing another device, verify the exact BGA ball map, power rails, configuration interface, I/O voltage standards, and speed grade rather than relying only on the logic-cell count. The C-grade suffix and -4 speed designation affect system timing and environmental requirements. Use the manufacturer's package pinout and configuration guidance to validate every board-level connection before production release. This product record combines the verified Spartan-3A device characteristics with package-aware replacement guidance, commercial sourcing instructions, and practical design notes for 256-ball FTBGA implementation. It is intended to accelerate initial component screening while preserving the verification work required for production-quality FPGA designs.

XC3S50A-4TQ144C

XC3S50A-4TQ144C - 50K Spartan-3A FPGA | AMD/Xilinx

The AMD/Xilinx XC3S50A-4TQ144C is a Spartan-3A field-programmable gate array with 55,296 system gates, 1,584 logic elements, 108 user I/Os, and a 144-pin TQFP package. Designed for high-volume, cost-sensitive commercial applications, the device uses a 90 nm process technology and a 1.2 V core. The “-4” grade identifies its performance speed grade, while the “C” suffix denotes the commercial temperature option. A field-programmable gate array, or FPGA, is a semiconductor whose digital logic, interconnect, and I/O resources are configured after manufacture. An FPGA sits within the programmable-logic hierarchy above simple fixed logic devices and below software-configured processors. Unlike a mask-programmable ASIC, an FPGA allows design revisions, field updates, and logic changes without fabricating a new custom chip. The XC3S50A-4TQ144C combines a moderate logic capacity with 108 user I/Os in a surface-mount TQFP package. The primary headline features are 55,296 system gates, 1,584 logic elements, and 108 user I/Os. Search results also describe the device as a 50,000-system-gate Spartan-3A FPGA. Its 144-pin TQFP package provides 108 user I/Os for external interfaces and board-level connections, making this device suitable for compact embedded systems requiring substantial parallel connectivity. The Spartan-3A architecture combines configurable logic, programmable I/O, dedicated memory resources, and clock-management resources within a single programmable device. The 90 nm fabrication process supports a compact and cost-sensitive implementation compared with larger, more complex programmable-logic devices. The device’s combination of moderate gate capacity and high I/O availability allows designers to consolidate control, interface, and state-machine functions without using a discrete combination of multiple smaller devices. Typical applications include industrial control, instrumentation, communications equipment, consumer peripherals, embedded control, and general-purpose I/O expansion. The 108 user I/Os are especially useful for systems that need parallel data acquisition, digital control, display interfaces, or external memory connections. In these designs, the FPGA can implement parallel processing and control logic while its configuration system preserves update flexibility. A primary design consideration is supply voltage and I/O compatibility. The available source material specifies a 1.2 V core but does not provide the complete recommended operating ranges, I/O standard options, configuration memory requirements, or power-loss configuration behavior. These values must therefore be confirmed against the complete manufacturer datasheet before schematic capture, pin assignment, and PCB layout are released. This product data consolidates verified distributor specifications, package information, pricing, availability, and same-family replacement options with practical selection guidance. It adds value beyond a basic distributor listing by separating confirmed parameters from missing technical data and explaining where each Spartan-3A option is appropriate.

XC3S50A-4TQ144I - 50K Spartan-3A FPGA | AMD/Xilinx

The AMD/Xilinx XC3S50A-4TQ144I is a Spartan-3A field-programmable gate array with 50,000 system gates, 1,584 configurable logic cells, 55,296 RAM bits, and 108 I/O in a 144-LQFP package. It operates from a 1.14 V to 1.26 V core supply and is specified for an industrial junction-temperature range of -40°C to 100°C. The -4 suffix identifies the device speed grade, while the TQ144 package designation identifies the surface-mount 144-lead package used by the XC3S50A family. A field-programmable gate array, or FPGA, is a semiconductor whose digital logic, interconnect, and I/O behavior can be programmed after manufacture. Within the product hierarchy, an FPGA is a programmable logic device and ultimately a semiconductor. Compared with a fixed-function application-specific integrated circuit, an FPGA allows parallel hardware functions, interface adaptation, and design revisions without changing the PCB. The Spartan-3A family is positioned for compact, cost-sensitive designs requiring moderate logic density and extensive user I/O. The Spartan-3A architecture provides five principal programmable functional elements, including configurable logic blocks, programmable interconnect, dedicated block RAM, input/output blocks, and configuration resources. Each configurable logic block contains four-input lookup tables and flip-flop resources for implementing combinational and sequential logic. The available 1,584 logic cells and 55,296 RAM bits support control logic, bus arbitration, low-speed communication interfaces, instrumentation, and general-purpose digital processing. With 108 I/O, the XC3S50A-4TQ144I offers more interface capacity than the smallest devices in the Spartan-3A family. The 144-LQFP package exposes those I/O along with configuration and power pins on a conventional surface-mount footprint. The 50,000-gate rating describes the family’s system-gate scale rather than a guaranteed clock rate, while the -4 speed designation and the manufacturer’s timing specifications determine actual performance. Configuration and pinout details should be verified against the DS529 family datasheet before PCB release. Typical applications include industrial control, telecommunications equipment, consumer electronics, embedded instrumentation, interface bridging, and low-density signal-processing systems. In each case, the combination of 1,584 logic cells, 55,296 RAM bits, 108 I/O, and a compact 144-lead package allows logic and interface functions to be consolidated without adopting a larger FPGA or a separate microcontroller for basic control tasks. Designers should preserve the required core-supply decoupling, use the manufacturer-recommended configuration interface, and confirm every signal’s I/O standard, drive strength, slew rate, and termination requirements against the DS529 datasheet. Programming tools, bitstream compatibility, and end-of-life considerations should also be reviewed because FPGA toolchains and family support evolve over time. This page consolidates verified distributor availability, package and resource details, drop-in replacement analysis, and practical design guidance into a compact engineering reference. It distinguishes documented device facts from parameters that still require manufacturer-data or board-level confirmation.

XC3S50A-4TQG144C - Spartan-3A FPGA, 108 I/O | AMD

The AMD XC3S50A-4TQG144C is a Spartan-3A field-programmable gate array with 15,840 logic cells, 108 user I/O, 1,584 internal configuration bits, and a 144-pin LQFP package. Its -4 speed designation supports operation up to 250 MHz, while 6.8 kB of block RAM provides dedicated on-chip storage for counters, packet buffers, and small data pipelines. The device is manufactured in a 1.2 V FPGA technology and targets compact embedded control, communications, instrumentation, and industrial logic systems. A field-programmable gate array is a semiconductor whose digital logic, interconnect, and input/output behavior are configured after manufacture. An FPGA belongs to the programmable-logic hierarchy, alongside CPLDs, but provides substantially more configurable logic and routing resources. This makes it suitable for parallel data acquisition, protocol conversion, control sequencing, embedded signal processing, and other designs that benefit from hardware concurrency. Configuration data determines the implemented circuit, allowing design revisions without changing the PCB. The Spartan-3A architecture combines programmable logic blocks, dedicated block RAM, digital clock management resources, and selectable I/O standards in a single device. The 108 I/O positions give a board designer substantial connectivity in a 144-lead surface-mount package. The 250 MHz headline operating figure should not be interpreted as a guaranteed logic-clock rate for every arbitrary design; actual timing depends on the selected clocking resources, routing path, I/O standard, speed grade, and board conditions. The -4 suffix identifies the device speed grade, while the TQG144C portion identifies the 144-pin package and device-grade ordering information. This ordering code must be checked against the PCB footprint, temperature grade, and production requirements rather than treated as interchangeable with every XC3S50A suffix. The Spartan-3A family is an established programmable-logic platform, and the official DS529 family data sheet remains the primary document for configuration requirements, pin descriptions, electrical characteristics, and package drawings. Typical uses include industrial control and data acquisition, serial-interface bridging, embedded communications gateways, low-cost test equipment, and compact embedded processing systems. A microcontroller can handle supervisory control while the FPGA performs deterministic sampling, protocol conversion, or parallel computations in parallel with the processor. Such partitioning reduces pressure on a general-purpose CPU and can simplify timing-sensitive implementations. Board design should follow the AMD package pinout and configuration guidance exactly. Confirm that the LQFP-144 footprint, power rails, decoupling, configuration interface, and JTAG connections match the selected board revision. Because the Spartan-3A is a mature architecture, also verify software-tool support, bitstream compatibility, and the availability of any required configuration memory before committing the design to production. This product record combines the exact XC3S50A-4TQG144C identifiers with the AMD family data sheet and same-package replacement analysis. It also highlights practical configuration, layout, timing, and thermal checks that engineers can apply when qualifying an FPGA design for low-cost, compact, or industrial equipment.

XC3S50A-4TQG144I - 50K Spartan-3A FPGA | AMD Xilinx

AMD Xilinx XC3S50A-4TQG144I is a Spartan-3A field-programmable gate array with 50,000 system gates, 1,584 configurable logic cells, 55,296 RAM bits, and 108 user I/O in a 144-LQFP package. The device operates from a 1.14 V to 1.26 V core supply and is implemented using 90 nm CMOS technology, with a stated maximum clock frequency of 667 MHz. A field-programmable gate array, or FPGA, is a semiconductor whose digital logic, interconnect, and I/O behavior are configured after manufacture. The XC3S50A belongs to the Spartan-3A hierarchy of low-cost FPGAs, combining programmable logic with block RAM and a high pin count. This makes it a practical platform for embedded control, protocol conversion, signal conditioning, and data acquisition where a fixed application-specific integrated circuit would be too specialized. The principal device characteristics include 1,584 logic cells organized into 176 logic array blocks, 55,296 bits of block RAM, and 108 user I/O. Its -4 speed designation corresponds to the stated 667 MHz performance level, while the industrial I suffix identifies the extended-temperature grade. The -40 °C to 100 °C junction-temperature range supports industrial and otherwise temperature-demanding equipment, provided the board-level thermal design keeps the junction within its rated limit. Spartan-3A devices combine programmable logic fabric, configurable I/O blocks, dedicated block RAM, and internal clocking resources on one die. The 1.2 V core architecture reduces supply requirements while leaving the I/O structure capable of supporting external system connections. Design timing, however, depends on the selected clock region, logic depth, routing congestion, I/O standards, and external timing budget, so the 667 MHz figure should not be interpreted as a guaranteed operating frequency for every design. Typical uses include industrial automation modules with sensors and actuators, telecommunications interface equipment, embedded display and control systems, and low-cost data-acquisition products. The 108 available user I/O are particularly useful when the design must bridge multiple buses, capture parallel signals, or provide discrete control outputs while keeping the logic in reprogrammable hardware. The principal design consideration is the 144-LQFP footprint. Place all decoupling capacitors close to the supply pins, preserve the manufacturer-defined VCC and ground connections, and assign I/O standards only through supported pins. Use the AMD Spartan-3A family data sheet for the complete pin table, configuration requirements, and board-level power sequencing before fabrication. This page combines device specifications, application guidance, engineering design notes, and a focused replacement comparison to help engineers evaluate the XC3S50A-4TQG144I beyond a basic distributor parameter listing.

AMD XC3S50A-4VQ100C is a Spartan-3A field-programmable gate array (FPGA) providing 1,584 logic cells, 55,296 RAM bits, 68 user I/Os, and approximately 50,000 logic gates in a 100-pin TQFP package. The device operates from a 1.14 V to 1.26 V core supply, uses 90 nm FPGA technology, and is implemented on a 0.667 GHz performance grade. A field-programmable gate array is a semiconductor device whose digital logic, memory, and I/O behavior are defined by a programmable configuration bitstream. An FPGA belongs to the programmable-logic hierarchy, alongside CPLDs, and provides reconfigurable parallel logic for cost-sensitive, I/O-intensive electronic products. Unlike a fixed-function application-specific integrated circuit, an FPGA can be reprogrammed during development or, where configuration technology permits, after deployment. The Spartan-3A family targets high-volume designs requiring moderate logic density. This device includes 176 configurable logic blocks, 68 user I/Os, and 55,296 bits of block RAM. Supported configuration approaches include Master Serial mode using platform flash PROM, Master SPI mode using commodity serial flash, BPI mode using commodity parallel flash, Slave Parallel mode using SelectMAP or a processor, and Slave Serial mode. These interfaces allow the configuration source and board-level design to be selected according to cost, density, and update requirements. The XC3S50A-4VQ100C is identified as a -4 speed-grade device with 667 MHz performance, a 1.2 V core, and a commercial operating-temperature range of 0°C to 85°C junction temperature. Its 100-terminal surface-mount package provides 68 user I/O positions according to the verified distributor data. Configuration data is retained externally in a PROM or flash device, so the FPGA's implemented logic is not fixed at manufacture. Typical uses include industrial control interfaces, communication adapters, instrumentation, test equipment, embedded control, and general-purpose programmable logic. Its 68 I/Os make it appropriate for parallel data acquisition, control, bridging, and interface-conversion designs where a small pin count, legacy 90 nm economics, and reconfigurability are more important than the density offered by newer FPGA families. The primary design consideration is that configuration storage, programming, clocking, decoupling, and I/O voltage compatibility must be planned before schematic capture. Designers should use the AMD Spartan-3A family data sheet for the exact package pinout and device-specific constraints, and should verify the selected configuration PROM against the supported bitstream and interface requirements. This page consolidates the verified AMD and distributor specifications, exact package and resource information, commercially sourced alternatives, and practical replacement-selection guidance. It is intended to help engineers identify whether the XC3S50A-4VQ100C remains appropriate for an existing Spartan-3A design without overlooking temperature-grade or speed-grade differences.

XC3S50A-4VQ100I - 50K Spartan-3A FPGA | AMD | Industrial

AMD XC3S50A-4VQ100I is a Spartan-3A field-programmable gate array with 50,000 system gates, 1,584 logic cells, 68 user I/Os, and a maximum stated performance of 667 MHz, supplied in a 100-pin TQFP package. The device operates from a 1.2 V core supply and is specified for industrial-temperature use from -40°C to +100°C. A Spartan-3A FPGA is a programmable logic device within the broader semiconductor and FPGA hierarchy. Unlike a fixed-function application-specific integrated circuit, it combines configurable logic, programmable interconnect, memory resources, and general-purpose I/O. Its 100-pin TQFP package makes it suitable for designs requiring moderate logic density and external peripheral connectivity without using a large ball-grid-array package. The XC3S50A-4VQ100I provides 1,584 logic cells and 68 I/Os, allowing designers to implement control logic, interface protocols, data acquisition, or embedded state machines in one programmable device. The -4 speed designation identifies its performance grade, while the I suffix identifies the industrial-temperature option reported in the verified product data. The 90 nm fabrication process and 1.2 V core supply are consistent with the Spartan-3A generation. Its architecture supports configuration from several serial and parallel memory interfaces, including Master Serial, Master SPI, BPI, Slave Parallel, SelectMAP, and Slave Serial modes. Configuration storage can therefore use commodity serial flash, parallel flash, or platform flash, depending on board-level requirements. The exact configuration file size, supported I/O standards, and recommended termination network are not included in the supplied source snippets. Typical uses include industrial automation, communications equipment, test and measurement systems, embedded control, and I/O-intensive consumer or industrial products. The 68 available I/Os support external sensors, displays, memory devices, and communications transceivers, while the 50K-gate device size is appropriate for moderate parallel logic rather than high-throughput processor applications. Design planning should include correct configuration-pin connections, suitable bypass capacitors, and a verified JTAG programming chain. The 100-TQFP footprint also requires careful escape routing for fine-pitch leads and adequate board area for power distribution. Because a detailed pin map and current pricing were not present in the supplied data, the package pinout is intentionally left unavailable and the commercial tiers require a current quotation. This product record consolidates verified distributor specifications, same-family drop-in candidates, application guidance, and practical FPGA design considerations. It is intended to help engineers assess package compatibility, configuration strategy, thermal requirements, and procurement without substituting unsupported electrical or lifecycle assumptions.

XC56309VF100A - 24-bit 100MHz DSP 196-MAPBGA | NXP Semiconductors

The NXP Semiconductors XC56309VF100A is a 24-bit fixed-point Digital Signal Processor (DSP) operating at a 100 MHz clock rate (100 MIPS), housed in a 196-pin MAPBGA (15x15 mm) surface-mount package. It belongs to the DSP563xx family, integrating 24 kB of on-chip RAM and 576 B of non-volatile memory, with Host Interface, SSI, and SCI peripherals for flexible system integration. What is a fixed-point DSP? A Digital Signal Processor (DSP) is a specialized microprocessor optimized for numeric-intensive signal processing tasks such as filtering, modulation, audio/video codecs, and telecommunications. Fixed-point DSPs represent data as integers, trading dynamic range for lower cost, lower power, and deterministic real-time latency compared to floating-point DSPs and general-purpose microcontrollers. They sit within the broader taxonomy: DSP -> processor -> microcontroller/ASIC family -> integrated circuit -> semiconductor. Key features of the XC56309VF100A include a 100 MHz core delivering 100 MIPS, 24-bit data paths, 24 kB on-chip RAM, 576 B ROM, and a Host Interface plus SSI and SCI serial ports. The device targets embedded signal-processing workloads requiring deterministic execution and large on-chip memory, which is essential for sample buffering in codecs and modem algorithms. The DSP563xx architecture uses a dual Harvard memory structure with separate program and data memories, enabling single-cycle instruction fetches and data accesses. The 196-MAPBGA package provides the pin density needed for the parallel Host Interface, ESAI/SSI serial audio port, SCI, and timers, while supporting industrial operating-temperature ranges of -40C to +105C junction. Typical applications include wireless infrastructure baseband processing, audio/speech codecs, modems, professional audio equipment, and industrial control systems. The 100 MIPS throughput is well matched to GSM channel cards, voice-band codecs (G.711/G.723/G.729), and consumer audio DSP where deterministic latency matters. When designing with this device, plan PCB layout carefully: the 196-ball MAPBGA requires microvia or laser-drilled via technology and matched-length traces on the Host Interface bus. Decoupling capacitors must be placed as close as possible to each power pin, and a 4-layer PCB with continuous power and ground planes is strongly recommended for signal integrity. This page synthesizes distributor pricing, drop-in alternatives from the DSP563xx family, and practical design notes not found in the manufacturer datasheet alone.

XC56L307VF160

XC56L307VF160 - 24-Bit Fixed-Point DSP, 160MHz | NXP / Freescale

The NXP (formerly Freescale) XC56L307VF160 is a 24-bit fixed-point Digital Signal Processor (DSP) running at 160 MHz core clock, packaged in a 196-ball LBGA (15 x 15 mm). It is part of the DSP56L300 family, designed for applications requiring large on-chip memory such as networking and wireless infrastructure. The device integrates up to 576 KB of on-chip RAM and features Host Interface, SSI, and SCI peripherals, with 3.30 V I/O. What is a Fixed-Point DSP? A Digital Signal Processor is a specialized microprocessor whose architecture is optimized for the high-throughput, real-time numeric workloads of signal processing. Fixed-point DSPs represent samples as integers (here, 24-bit words) and execute multiply-accumulate operations in a single cycle, making them well-suited for cost-sensitive and power-sensitive signal chains. They sit within a broader hierarchy of: DSP -> microprocessor -> microcontroller -> semiconductor device. Key features of the XC56L307VF160 include a 24 x 24-bit program RAM expansion area with a 24-bit instruction cache, a small 576-byte ROM area for boot/test code, and a memory architecture geared toward high-data-rate streaming applications. The 196-LBGA package and industrial temperature grade make it a common choice in densely-populated, thermally-contained systems. Technically, the DSP56L307 uses a dual Harvard-style architecture with separate program and data memory spaces. The 24-bit datapath provides extended dynamic range for codec and modem algorithms, and the SSI (Synchronous Serial Interface) supports connection to common audio and voice codecs. The 160 MHz clock rate yields 160 MIPS of arithmetic throughput for typical MAC-heavy DSP kernels. Typical applications include VoIP gateways, audio processing for conferencing systems, wireless baseband front-end processing, and industrial control loops where deterministic DSP performance is required. The combination of large on-chip memory and a strong peripheral set removes the need for an external SRAM, lowering system BOM cost. When designing with this part, ensure your PCB layout provides adequate thermal dissipation through internal power/ground planes, because the LBGA package dissipates heat almost entirely through the PCB. Use the manufacturer reference design to validate ball-pin escape routing.

XC5VLX30-1FF324I

XC5VLX30-1FF324I - 30,720-Cell Virtex-5 LX FPGA | AMD

The AMD XC5VLX30-1FF324I is a Virtex-5 LX field-programmable gate array with 30,720 configurable logic cells, 220 I/O, and a 324-ball FCBGA package. It is a -1 speed-grade device with an industrial-temperature ordering suffix, designed for programmable digital logic, signal processing, interface bridging, communications, and embedded control systems. The device provides 1,179,648 FPGA gates, as identified in the product listing, while its architecture integrates programmable logic, block RAM, dedicated input/output resources, and configurable interconnect resources into one reconfigurable semiconductor package. A field-programmable gate array, or FPGA, is a digital integrated circuit whose logic, memory, and I/O behavior is defined after fabrication. An FPGA belongs to the broader programmable-logic hierarchy, which includes complex programmable logic devices and other reconfigurable digital semiconductors. Compared with a fixed-function application-specific integrated circuit, an FPGA allows parallel processing, hardware customization, in-system updates, and shorter development cycles for algorithms that benefit from simultaneous operations. The XC5VLX30 combines a 30,720-cell Virtex-5 LX implementation with 220 I/O in a compact 324-ball FCBGA package. The 220-I/O interface supports external memory, data converters, network transceivers, clock sources, and parallel peripherals, although final signal counts depend on the selected pin assignments and device constraints. Its substantial programmable logic fabric is useful for protocol handling, packet processing, filter implementations, finite-state-machine control, and custom datapaths. The “-1” portion identifies the device speed grade, while the “I” suffix denotes the industrial temperature option. These ordering details are important because the device is not simply interchangeable with every Virtex-5 LX configuration. A replacement must match the XC5VLX30 resource count, 324-ball footprint, pin assignment, speed grade, temperature range, voltage requirements, configuration interface, and any legacy or production requirements applicable to the original design. Typical uses include industrial networking equipment, test and measurement systems, video processing, communications infrastructure, embedded instrumentation, and high-speed control logic. In these systems, the FPGA can execute multiple parallel channels, maintain precise timing, or implement custom protocols while reducing reliance on external programmable devices. PCB implementation requires careful attention to power integrity, decoupling, clock routing, differential-pair geometry, and thermal performance of the large FCBGA package. Use the pinout and board-layout guidance in the manufacturer documentation, preserve the required power and ground planes, and validate signal-integrity and power-delivery margins before releasing the PCB. This page organizes the exact catalog identifiers, package information, sourcing details, technical comparisons, and practical replacement considerations for engineers evaluating the XC5VLX30-1FF324I in new or existing Virtex-5 LX designs.

XC5VLX30-1FF676C

XC5VLX30-1FF676C - 30K Logic Cell Virtex-5 LX FPGA, 676-BBGA | Xilinx

The Xilinx XC5VLX30-1FF676C is a Virtex-5 LX field programmable gate array (FPGA) providing 30,720 logic cells, 400 user I/O and approximately 1,179,648 gates in a 676-ball FCBGA (676-BBGA) package at the -1 speed grade. It is a member of the Virtex-5 family built on the second-generation ASMBL column-based architecture and is targeted at high-performance logic, DSP and multi-gigabit serial interface designs. An FPGA is a programmable semiconductor whose logic fabric, block RAM and dedicated hardware resources are configured at power-up from a bitstream held in external flash. Within the device hierarchy, the XC5VLX30-1FF676C sits in the Virtex-5 LX platform: Virtex-5 family, Virtex-5 LX sub-family, then LX device class, then the specific XC5VLX30 density. LX devices combine general-purpose configurable logic, dedicated DSP48E slices and multi-gigabit transceiver resources, making them the general-purpose member of the Virtex-5 line compared with the smaller Spartan-3 devices. Key features of this part include the 676-ball flip-chip BGA package with a 1.0 mm ball pitch footprint, a -1 performance speed grade, and full Virtex-5 LX configuration support through ISPEED, CORE Generator and ISE Design Suite. The -1 suffix denotes the mid-range speed bin, which balances timing closure margin against cost and power versus the faster -2 grade. The 'C' package suffix denotes the commercial temperature grade, and the 'FF' package code identifies the 676-ball FCBGA option. Architecturally the device uses the ASMBL column-based fabric with slice-based logic elements, distributed and block RAM, and dedicated DSP48E multiplier-accumulator blocks. Configuration data is loaded through the standard 8-bit or parallel JTAG/serial configuration ports, and the device supports multi-boot configuration handling for field updates. Because the fabric is SRAM-based, the configuration memory is volatile and a bitstream must be reloaded after each power cycle. Typical applications for the XC5VLX30-1FF676C include telecommunications line cards and aggregation equipment, industrial control and test instrumentation, high-speed data acquisition, video and image processing pipelines, and any design needing multiple high-speed serial transceivers with logic capacity beyond small Spartan devices. It also serves well in prototype-to-production migration paths where a single 676-ball board footprint must support several density options. Design considerations center on power delivery to the large BGA array and on thermal performance. A 676-ball FCBGA demands a multilayer PCB with a solid ground plane and careful decoupling close to every supply ball; use of a plane-power structure with stitching vias prevents supply droop at high toggle rates. Because Virtex-5 LX devices are legacy technologies, confirm availability and lifecycle status with AMD before committing to a long production run, and confirm the exact I/O standard, clocking resources and transceiver capabilities required by your design in the manufacturer datasheet. This page consolidates distributor availability, verified drop-in alternatives in the same 676-ball footprint, and practical implementation guidance that engineers would otherwise have to piece together from multiple sources.

The AMD XC5VLX30-1FF676I is a Virtex-5 LX field-programmable gate array with 30,720 logic cells, 400 I/O, a 1098 MHz listed operating frequency, and a 676-ball FCBGA package. The device is specified as industrial grade and operates from a 1 V supply, making it suitable for embedded systems requiring programmable logic, parallel interfaces, control functions, and high-speed digital signal processing. An FPGA is a programmable semiconductor in which the logic fabric, interconnect, and input/output resources can be configured after manufacture. The Virtex-5 LX family belongs to the broader FPGA and CPLD hierarchy, combining configurable logic blocks, programmable interconnect, block RAM, dedicated input/output resources, and embedded processor options. This makes the XC5VLX30-1FF676I useful when a design needs flexible hardware behavior, rapid design revisions, or parallel hardware acceleration without committing the function to a custom ASIC. The device provides 30,720 logic cells organized into 2,400 configurable logic blocks and offers 400 I/O in a 676-ball, 27 mm by 27 mm FCBGA package. Its industrial temperature grade differentiates it from commercial-grade XC5VLX30 variants. The 1 V operating supply supports low-voltage system integration, while the large ball-count package exposes the substantial I/O and power-distribution resources associated with a high-performance programmable logic platform. The XC5VLX30-1FF676I is identified by the XC5VLX30 base device, the -1 speed grade, the FF676 package and finish designation, and the I industrial-temperature suffix. Similar suffix combinations can change speed grade, temperature grade, package finish, or lead-free status without changing the underlying Virtex-5 LX device family. Consequently, replacement decisions must compare all ordering suffixes rather than treating every XC5VLX30 part as interchangeable. Typical applications include industrial control systems, test and measurement equipment, communications infrastructure, embedded video processing, network-interface equipment, and high-throughput data acquisition. The 400 available I/O positions are particularly useful for parallel buses, clock distribution, control signals, and interfaces to external converters or memories. The 30,720-cell fabric can implement parallel datapaths, protocol engines, state machines, and fixed-function blocks concurrently rather than forcing them into a sequential microcontroller architecture. When assigning this FPGA to a board, verify power sequencing, decoupling, clocking, configuration memory, bank-voltage constraints, and the complete 676-ball footprint before layout. The large FCBGA package also requires careful via-in-pad or via-under-bump construction, differential-pair routing, and thermal design. Use the manufacturer pinout and design-support documentation to assign every power, ground, configuration, clock, and user I/O ball correctly. This product page combines the exact ordering information, package details, search-query coverage, practical design guidance, and a parameter-by-parameter comparison of verified drop-in alternatives. It also distinguishes same-footprint candidates from changes that affect speed grade or temperature range, helping engineers shortlist replacements without overlooking qualification and lifecycle constraints.

A field-programmable gate array, or FPGA, is a programmable semiconductor in which digital logic is configured after manufacture. The FPGA category sits above programmable logic and configurable logic arrays and provides configurable blocks, programmable routing, and general-purpose I/O for parallel interface, control, processing, and signal-processing functions. Virtex-5 devices use Xilinx ASMBL column-based architecture, allowing system functions to be implemented as hardware rather than through sequential software execution. The XC5VLX30 provides 30,720 logic cells and 220 configurable I/O in a compact square FCBGA package. Its 19 mm by 19 mm package supports high-density board layouts where larger leaded packages would be impractical. The target MPN includes the -2 performance designation and the C commercial-temperature grade, distinguishing it from faster, industrial-temperature, or otherwise differently suffix-coded members of the same device family. The 1 V core voltage reflects the low-voltage operation associated with 65 nm FPGA technology. Designers must provide suitable supply rails and decouple the power rails close to the device because high-speed switching inside the programmable array can create transient current demands. The manufacturer datasheet remains the controlling reference for pin assignment, configuration pins, clock requirements, power sequencing, and exposed-pad connections. Typical uses for this FPGA include embedded industrial control, communications infrastructure, high-speed data acquisition, image and video processing, network equipment, and test-and-measurement systems. Its combination of logic capacity and 220 I/O is appropriate for designs requiring parallel interfaces and multiple externally accessible signals rather than a very small control-only design. Board design should begin with the exact FF324C pinout and power tables in the manufacturer datasheet. Confirm ball assignments, configuration mode, clock connectivity, voltage requirements, and thermal-management details before layout. Because this is a complex BGA device, escape routing, plane continuity, via structures, and solder-mask design require deliberate PCB engineering rather than a generic component footprint assumption. This page combines the exact device identity, package and electrical facts, qualified same-family alternatives, comparison parameters, sourcing guidance, and practical integration notes. It is intended to help engineers narrow the replacement decision while preserving the requirement for an exact package, pin-compatible footprint, and appropriate speed and temperature grade.

It uses 65 nm CMOS technology and operates from a 0.95 V to 1.05 V core supply. The industrial-temperature suffix I supports an operating junction-temperature range of -40°C to 100°C. The -2 speed grade, 676-ball package, and FPGA architecture place it in the Virtex-5 LX family for configurable logic, embedded processing, high-speed serial connectivity, and system-level signal processing. A field-programmable gate array is a programmable digital integrated circuit whose interconnect and logic resources are configured after manufacture. An FPGA belongs to the broader hierarchy of programmable logic devices, semiconductor integrated circuits, and digital electronics. Unlike a fixed-function application-specific integrated circuit, a Virtex-5 LX FPGA can implement parallel processing, control, protocol, and interface logic in one device, allowing hardware behavior to be revised without changing the printed circuit board. The XC5VLX30 provides 2,400 logic blocks according to the device overview, together with 30,720 logic cells for constructing datapaths, state machines, controllers, and arithmetic pipelines. Its 1,179,648 bits of block RAM allow substantial data buffering and dual-port storage without external memories.

The 676-ball FCBGA measures 27 mm by 27 mm and supports dense PCB routing required by large Virtex-5 designs. The -2 designation identifies the device performance grade within the Virtex-5 LX family, while I identifies the industrial temperature option. Device configuration and bitstream loading are central to using an FPGA because the interconnect, logic resources, block RAM, and I/O behavior are established through programmable configuration data. In multi-rail systems, power sequencing, configuration access, and ancillary voltage rails must be coordinated with the device's system power-management design. Typical uses include telecommunications line-card control, industrial automation, high-throughput signal processing, network-interface data planes, instrumentation, and ASIC prototyping. The large I/O count is particularly useful when a design combines multiple bus widths, memory interfaces, clock domains, and high-speed serial links. The device can consolidate programmable control and datapath functions that might otherwise occupy several fixed-function devices, although implementation complexity and FPGA resource planning remain important considerations. PCB design requires careful treatment of the FCBGA escape routing, power delivery, decoupling, and thermal path.

XC5VLX30-3FF324C - Virtex-5 LX 30K Logic Cell FPGA, 324-BBGA
XC5VLX30-3FF324C

XC5VLX30-3FF324C - Virtex-5 LX 30K Logic Cell FPGA, 324-BBGA

The AMD (Xilinx) XC5VLX30-3FF324C is a Virtex-5 LX field-programmable gate array (FPGA) with 30,720 logic cells, 220 user I/O, and 1,179,648 bits of block RAM, offered in a 324-ball flip-chip BGA (FCBGA) package. It is built on the second-generation ASMBL column-based architecture and targets the -3 speed grade. An FPGA (field-programmable gate array) is a programmable logic device: a matrix of configurable logic blocks (CLBs) and programmable interconnect that can be reconfigured at the field to implement any digital design from a single HDL source. In the Xilinx hierarchy, Virtex-5 LX is a general-purpose platform family that sits above the smaller Spartan-3 family and below the larger Virtex-5 LXT/SXT and Virtex-6 device families. The Virtex-5 LX family targets networking, telecommunications, industrial control, and embedded systems requiring medium logic density with high-speed serial and memory resources. Key features of the XC5VLX30-3FF324C include 30,720 logic cells organized in 4,800 4-input LUTs, 1,179,648 bits (1.125 Mbit) of 18 Kb block RAM, and 220 I/O distributed across the 324-BBGA package. The -3 speed suffix denotes the faster of the standard Virtex-5 LX performance grades. The device is offered in a monolithic 324-ball FCBGA package with a square body and ball terminals. Architecturally, the XC5VLX30 uses the ASMBL column-based fabric, with configurable logic blocks, dedicated 18 Kb block RAM tiles, 18x18 multiplier accumulators, and dedicated distributed RAM per LUT. Because the fabric is column-based, routing between columns is highly regular and repeatable, which simplifies timing closure compared with row-based fabrics of the previous generation. Typical applications include network interface and line-card designs, industrial control and test equipment, telecom baseband and cross-connect equipment, mid-range embedded video processing, and any design needing a mid-density programmable logic engine in a single 324-ball package. A key design consideration is that the Virtex-5 LX family is a mature generation: new designs should be reviewed against current-generation AMD devices where board area, power, and toolchain support allow, while existing Virtex-5 platforms can reuse the same pinout and bitstream tool flow. This page consolidates parametric details, drop-in replacement candidates for the 324-BBGA footprint, and practical design guidance that is not assembled in one place in the manufacturer documentation.

XC5VLX30-3FF676C - 30,720-Cell FPGA | AMD | Industrial

The AMD XC5VLX30-3FF676C is a Virtex-5 LX field-programmable gate array with 30,720 logic cells, 2,400 configurable logic blocks, and a 676-ball FCBGA package. The device uses 65 nm CMOS technology, operates from a 1 V core supply, and provides 400 input/output pins for logic-intensive digital systems. A field-programmable gate array is a programmable-logic semiconductor that combines configurable logic blocks, programmable interconnect, input/output resources, and embedded memory into one reconfigurable device. Within the product hierarchy, an FPGA is a programmable-logic IC, a semiconductor, and a flexible alternative to a large fixed-function ASIC. It allows designers to implement parallel processing, protocol bridging, interface control, and high-speed digital logic in a single integrated circuit. The XC5VLX30 includes 30,720 logic cells organized into 2,400 configurable logic blocks. Its 400 I/O pins provide substantial connectivity for external memory, data converters, networking interfaces, and control logic. The -3 suffix denotes the device's performance grade within the Virtex-5 LX ordering system, while the 676-ball package supports dense, high-pin-count board-level integration. The FCBGA construction also provides numerous short electrical connections for demanding digital routing requirements. The XC5VLX30 is fabricated using 65 nm CMOS technology and is built around a 1 V core-voltage architecture. This combination supports high programmable logic density while preserving the operating characteristics expected from a high-performance FPGA family. Device interchangeability must still account for the speed grade, package suffix, temperature grade, and power requirements rather than treating every similarly numbered Virtex-5 device as electrically identical. Typical applications include telecommunications line-card and switching equipment, industrial control systems, network interface equipment, high-speed test and measurement platforms, signal-processing installations, and embedded control systems requiring reconfigurable parallel logic. The large pin count is particularly useful when a design must connect several memory devices, high-speed transceivers, parallel buses, or multiple independent I/O interfaces. PCB implementation requires careful attention to the 676-ball package geometry, power-plane continuity, decoupling, and high-speed signal routing. Follow the AMD Virtex-5 package pinout files for the exact ball assignments and differential-pair constraints. Verify the required configuration voltage, clock topology, memory interface routing, and thermal conditions in the applicable Virtex-5 device documentation before releasing a layout. This page combines exact ordering information, a practical application view, same-footprint device alternatives, and design guidance for engineers evaluating the XC5VLX30-3FF676C in a new programmable-logic platform.

XC5VLX50-1FF324C

XC5VLX50-1FF324C - Virtex-5 LX FPGA, 46,080 Cells | AMD

The AMD XC5VLX50-1FF324C is a Virtex-5 LX field-programmable gate array with 46,080 logic cells, 1,769,472 FPGA-equivalent gates, and 220 I/O in a 324-ball FCBGA package. The -1 suffix identifies the device speed grade, while the C suffix identifies the commercial grade variant. This combination makes the XC5VLX50-1FF324C suitable for designs requiring substantial parallel processing, programmable logic, dedicated block resources, and a high pin count within an established FPGA platform. An FPGA is a semiconductor whose digital functions are defined by loading a configuration bitstream after manufacture. The Virtex-5 LX belongs to the Virtex-5 family of platform FPGAs and uses a column-based architecture for implementing general-purpose logic alongside dedicated resources. Compared with an application-specific integrated circuit, an FPGA allows design changes, parallel processing, and hardware acceleration without requiring a new custom silicon fabrication run. The XC5VLX50-1FF324C provides 46,080 logic cells and 220 I/O, giving an engineer a substantial fabric for control logic, protocol handling, image processing, data acquisition, and interface consolidation. Its 324-ball FCBGA package supports a high connection count compared with smaller leaded or perimeter-only packages. That density makes the device appropriate for complex system designs that require numerous high-speed signals and board-level integration. The -1 speed designation places the device in the performance class identified by the manufacturer part numbering system. The C suffix denotes the commercial-grade ordering option. Exact operating-voltage limits, temperature limits, supported I/O standards, block-RAM quantities, DSP resources, and clock-management details must be confirmed in the Virtex-5 device documentation before a production design is released. Typical uses include telecommunications line-card control, industrial automation, video and image-processing pipelines, test equipment, embedded instrumentation, and high-throughput data-acquisition systems. In these applications, the FPGA can execute multiple parallel processing channels, implement protocol bridges, and combine control functions with dedicated accelerator blocks while preserving software-updatable field behavior. PCB design requires careful attention to power, ground, configuration, clock, and high-speed signal integrity. Use the manufacturer package pinout files to assign every ball and plane connection, and follow the documented power-supply sequencing and decoupling requirements. A migration from another Virtex-5 device with a different package should not be assumed to be pin-compatible because BGA ball assignments and power distribution can change with package construction. This page organizes the device identity, verified package data, sourcing routes, comparable ordering variants, and practical design considerations into one engineering reference. It also distinguishes true package-level replacements from speed-, temperature-, and package-family options so engineers can avoid treating an electrically similar FPGA as a drop-in replacement.
