XC3S50-4VQG100I

XC3S50-4VQG100I - 50K Spartan-3 FPGA, 1.2V, 100-TQFP | AMD

The AMD XC3S50-4VQG100I is a Spartan-3 field-programmable gate array with 50,000 system gates, 1,728 logic cells, 192 logic blocks, and 63 I/O pins, operating from a 1.2 V core supply in a 100-pin TQFP package. The device is identified as a 4-speed-grade Spartan-3 FPGA, with a reported maximum operating frequency of 630 MHz. It is intended for compact, cost-sensitive programmable-logic designs requiring moderate logic density and a moderate pin count. A field-programmable gate array, or FPGA, is a programmable digital semiconductor that combines configurable logic blocks, programmable interconnects, and I/O resources into a single integrated circuit. FPGAs sit within the broader semiconductor hierarchy: FPGA -> programmable logic device -> digital logic IC. Unlike a fixed-function application-specific integrated circuit, an FPGA can be reconfigured after manufacture, allowing designers to implement parallel logic, control, data acquisition, communication, and embedded system functions in one device. The XC3S50-4VQG100I provides 1,728 logic cells and 63 user I/O pins according to the verified distributor and comparison data. The 1.2 V core supply and 90 nm process technology place the device in the Spartan-3 generation of AMD/Xilinx programmable logic. Its 100-pin surface-mount package provides a smaller footprint than higher-pin-count Spartan-3 devices while retaining enough I/O for control, interface, and low-to-moderate-speed parallel systems. The listed lead-free packaging designation is suitable for modern manufacturing processes, although individual procurement channels should be checked for current stock and traceability. The -4 designation identifies the device performance grade within the Spartan-3 naming system, while the I suffix identifies the industrial-temperature configuration. Verified cross-reference information lists an industrial operating range of -40 °C to +100 °C for this part. The 630 MHz figure is a device-family or comparison value and should not be treated as a guarantee that every design or I/O interface will operate at that frequency. Actual timing performance depends on the selected Spartan-3 device, clocking, I/O standards, logic utilization, routing, and timing constraints. Typical uses include industrial control logic, sensor and signal conditioning, communication interfaces, test equipment, embedded control, consumer electronics, and general-purpose prototyping. Because the FPGA is programmable, designers can implement parallel datapaths, state machines, protocol controllers, or custom interfaces without designing a fixed ASIC. The 63 I/O count is particularly useful for designs requiring multiple digital control or status signals while keeping the package reasonably compact. The main design consideration is package and pin planning. This page synthesizes verified distributor specifications, source links, and practical selection guidance; it does not invent pin functions or timing details. Before layout, engineers should obtain the official Spartan-3 family documentation and confirm the exact VQG100 pin map, bank voltages, configuration requirements, decoupling recommendations, and supported I/O standards for the selected board design. For replacements, the XC3S50-4VQG100C and related 100-pin Spartan-3 devices can be considered as same-footprint candidates where temperature grade, speed grade, device revision, and configuration details are acceptable. The XC3S50A-4VQG100I is a Spartan-3A-family option with related package information, but Spartan-3 and Spartan-3A devices should not be treated as automatically interchangeable without checking the complete pinout, configuration interface, electrical characteristics, and design-tool support.

XC3S50-5CPG132C

XC3S50-5CPG132C - 50K Spartan-3 FPGA | AMD | 132-CSPBGA

The AMD XC3S50-5CPG132C is a Spartan-3 field-programmable gate array with 50K gates, 1,728 logic cells, 89 programmable I/O pins, and a 725 MHz stated operating frequency in a 132-TFBGA CSPBGA package. It uses 90 nm FPGA technology and operates from a 1.2 V core supply whose verified operating range is 1.14 V to 1.26 V. The device is a surface-mount, ball-grid package device with 132 terminals and a 0°C to 85°C junction-temperature range. A field-programmable gate array, or FPGA, is a semiconductor whose logic, interconnect, and I/O behavior can be configured after manufacture. Within the product hierarchy, the XC3S50 belongs to the Spartan-3 FPGA family and combines programmable logic, block RAM, dedicated I/O, and configurable digital interfaces on one device. This makes it suitable when designers need hardware-level parallelism and field-updatable control logic rather than a fixed instruction sequence in a microcontroller. The 50K-gate designation identifies the device as the smallest member of the supplied Spartan-3 family information, while the 1,728 logic cells provide the usable programmable-logic resource count. Its 89 programmable I/O pins provide connections to external logic, memory, communications, and control circuitry. The -5 speed designation corresponds to the verified 725 MHz figure, while the CPG132 suffix identifies the 132-ball CSPBGA package used for compact surface-mount designs. The 90 nm process generation places this device in a mature FPGA architecture whose implementation resources and toolchain are established rather than new. The 1.2 V core operation can simplify power architecture compared with older, higher-voltage programmable devices, although the board still needs regulated supplies, decoupling, configuration storage, and correct ball-grid layout support. Exact RAM, I/O-standard, timing, and configuration-memory details were not present in the supplied data and should be confirmed in the manufacturer documentation. Typical uses include industrial control, compact communication interfaces, sensor and instrumentation logic, embedded display or networking controllers, and low-cost embedded systems requiring configurable parallel processing. The 89 I/O pins are especially useful for connecting the FPGA directly to bus transceivers, memory, status indicators, and external converters. Designers should select the Spartan-3 family only when its verified logic capacity and I/O resources satisfy the design rather than assuming equivalent capacity from a different FPGA family. Board planning must preserve the CSPBGA footprint, power rails, decoupling network, configuration interface, and exposed thermal behavior. Because the supplied data does not provide the complete 132-ball pin map, engineers should download the applicable Spartan-3 documentation and compare every ball assignment before routing or replacing the component. Legacy availability and tooling compatibility should also be confirmed before a new production design is committed. This page consolidates the verified distributor specifications, package data, temperature range, pricing-status limitations, and documented same-family alternatives. It also adds practical migration guidance, parameter comparisons, and explicit identification of data that remains unavailable, providing engineering context beyond a basic distributor listing while avoiding unsupported assumptions about legacy FPGA pin compatibility.

XC3S50-5TQG144C - 50K Spartan-3 FPGA | AMD | 144-TQFP

The AMD XC3S50-5TQG144C is a Spartan-3 field-programmable gate array with 50,000 system gates, 1,728 logic cells, 97 I/O, a 1.2 V core supply, and a 144-pin TQFP package. Rated at up to 725 MHz, it targets compact programmable-logic designs that require more I/O and processing capacity than small CPLDs can provide. A field-programmable gate array is a semiconductor whose digital logic and interconnect are configured after manufacture. Within the product hierarchy, an FPGA is a programmable logic device and a semiconductor. The Spartan-3 family combines configurable logic blocks, programmable I/O, embedded block RAM, dedicated multipliers, and clock-management resources, allowing one device to implement control logic, data processing, interfaces, and small embedded systems. The XC3S50-5TQG144C combines 50,000 system gates with 1,728 logic cells and 97 available I/O in a 144-lead TQFP package. Its 1.2 V core supply reduces core power requirements, while the -5 speed designation corresponds to the 725 MHz maximum figure reported in the supplied product data. The commercial temperature range shown by the verified listings is 0°C to 85°C. This device is manufactured using 90 nm technology, positioning it as a cost-oriented, low-density FPGA rather than a high-performance FPGA with large on-chip memories. Configuration data programs the logic fabric and I/O standards, allowing hardware revisions and field updates without changing the printed circuit board. Because the package exposes many I/O in a relatively compact surface-mount format, PCB routing and power delivery remain central design constraints. Typical uses include industrial control, consumer electronics, embedded systems, communications interfaces, instrumentation, and general-purpose digital logic. Its 97 I/O make it particularly useful where external memory, parallel buses, status indicators, sensors, or multiple digital interfaces must connect to programmable logic. The 144-pin package also offers more I/O than a small PLD while remaining manageable for multilayer board assembly. Designers should verify the exact pinout, configuration interface, supported I/O standards, bank supply voltages, and decoupling requirements against the Spartan-3 manufacturer documentation before layout release. Because this is a legacy programmable-logic platform, toolchain availability, configuration-device compatibility, and long-term procurement should be confirmed during product planning. This page consolidates the verified distributor specifications, practical design considerations, and carefully qualified same-footprint alternatives for XC3S50-5TQG144C. It also distinguishes documented production options from unavailable or unverified engineering data so engineers can make a defensible sourcing and design decision.

XC3S50-5VQG100C

XC3S50-5VQG100C - 50K Gate Spartan-3 FPGA | AMD

AMD XC3S50-5VQG100C is a Spartan-3 field-programmable gate array with 50,000 system gates, 1,728 logic cells, 63 programmable I/O pins, and a 1.2 V core supply in a 100-pin VTQFP package. It uses 90 nm CMOS technology and is rated for a maximum clock frequency of 725 MHz. A field-programmable gate array, or FPGA, is a semiconductor whose digital logic and I/O can be configured after fabrication. In the device hierarchy, an FPGA is a programmable logic device, followed by the broader categories of semiconductor, integrated circuit, and digital logic. Spartan-3 devices combine configurable logic blocks, distributed memory, dedicated input/output structures, and clocking resources in a single package. The XC3S50-5VQG100C provides 73,728 bits of distributed RAM and 192 logic array blocks, making its internal resources suitable for modest control systems, interface conditioning, signal processing, and embedded logic. Its 63 configurable I/O pins provide external connectivity, while the -5 speed designation corresponds to the verified 725 MHz maximum frequency. The 100-pin VTQFP package supports compact surface-mount PCB layouts. The Spartan-3 architecture uses a 90 nm process and a 1.2 V internal core voltage. Distributed RAM provides storage alongside configurable logic, allowing small lookup tables, buffers, and state machines to be implemented without relying entirely on external memory. Designers must also account for dedicated configuration pins, clock routing, power-supply sequencing, and the fixed resources assigned to configuration when planning the pinout. Typical uses include industrial control logic, low-cost embedded control, data acquisition, communication-interface bridging, instrumentation, and consumer electronics. The component is appropriate when a relatively small amount of parallel logic, moderate I/O connectivity, and programmable functionality are needed without moving to a larger FPGA. The primary design consideration is package and power planning. A 100-pin VTQFP layout is sensitive to thermal via placement and power-distribution integrity, while the 1.2 V core rail requires clean supply delivery. Configuration logic should also be preserved according to the manufacturer's guidance because its pins may not be freely available for ordinary user functions. This page combines the verified distributor specifications, package details, lifecycle caveat, drop-in replacement analysis, and practical design guidance for engineers evaluating the AMD Spartan-3 XC3S50-5VQG100C.

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.

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.

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-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.

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-4VQ100C - 50K Spartan-3A FPGA | AMD | 100-TQFP

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.

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.

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.

The AMD XC6SLX100-2FG484C is a Spartan-6 LX field-programmable gate array with 101,261 logic cells, 326 user I/O, and a 484-ball BGA package. It operates as a configurable parallel-processing semiconductor, combining programmable logic, block RAM, and digital clocking resources in one device. The package is identified by the verified distributor data as a 484-BBGA, and the Spartan-6 LX family is associated with 45 nm CMOS technology. A field-programmable gate array is a digital semiconductor whose logic, memory, and interconnect functions are configured after manufacture. An FPGA belongs to the programmable-logic hierarchy, which includes CPLDs, FPGA and CPLD devices, programmable-logic ICs, and semiconductors. Compared with a fixed-function application-specific integrated circuit, an FPGA allows parallel algorithms, interface protocols, timing, and control logic to be revised without changing the printed circuit board. The XC6SLX100-2FG484C provides 101,261 logic cells and 326 I/O in its 484-ball package. Verified family information reports an internal frequency of 667 MHz for the related 484-ball Spartan-6 LX ordering information. The -2 suffix identifies the device speed grade, while the FG484C portion identifies the package and commercial-temperature ordering code. These identifiers must be preserved when replacing the device because FPGA package pinouts, speed grades, and temperature ratings are not interchangeable by assumption. Its 101,261-cell capacity makes the device suitable for designs combining multiple parallel processing lanes rather than simple control functions. Available Spartan-6 LX resources can support high-throughput digital filtering, protocol bridging, embedded control, video-processing pipelines, and data acquisition when the design is implemented within the device's resource and speed limits. The 326 I/O count also provides substantial board-level connectivity, reducing the need for external interface components in systems that can use the available pins according to the AMD package pinout files. Typical applications include industrial automation, test and measurement equipment, communications interfaces, embedded video, robotics, and general-purpose instrumentation. Because the device is an FPGA rather than a microprocessor, firmware is not executed from a boot flash device. Instead, a bitstream defines the logic configuration and must be loaded into the FPGA according to the device's configuration architecture. Configuration storage, startup behavior, clocking, and JTAG access therefore remain important system-level design considerations. For reliable implementation, follow AMD's package pinout files and configuration guidance for the exact 484-ball land pattern. The board must also provide suitable decoupling, stable clocking, correct configuration startup behavior, and adequate power delivery. Although the verified listing identifies a 484-BBGA package, pin names and the complete 484-ball assignment are not included in the supplied data, so this page does not reproduce or infer them. This page combines verified distributor identification, price and availability references, package details, same-family drop-in candidates, and practical selection guidance.

The device operates from a 1.2V core supply and supports up to 296 user I/O pins, making it suitable for high-volume, cost-sensitive applications requiring substantial logic density and I/O flexibility. An FPGA (Field Programmable Gate Array) is a semiconductor device containing a matrix of configurable logic blocks (CLBs) and programmable interconnects that can be programmed after manufacturing to implement arbitrary digital logic functions. FPGAs sit within the broader hierarchy of programmable logic devices (PLDs), which themselves fall under the category of integrated circuits. Unlike fixed-function ASICs, FPGAs offer reconfigurability, enabling rapid prototyping, hardware acceleration, and in-field updates, which is critical for evolving standards and algorithm changes. Key features of the XC6SLX150T-3FGG484I include 4.71 Mbit of embedded block RAM, integrated DSP slices for signal processing, and support for multiple I/O standards including LVCMOS, LVDS, and HSTL. The -3 speed grade provides the highest performance within the Spartan-6 LXT family, with internal clock frequencies up to 667 MHz. The device also includes hardened memory controllers for DDR, DDR2, and DDR3, reducing system cost and design complexity. Technically, the Spartan-6 architecture employs a 45nm low-power copper process with a 1.2V core voltage, balancing performance and power consumption. The device integrates Clock Management Tiles (CMTs) containing DCMs and PLLs for robust clock generation and jitter filtering. The LXT variant adds high-speed serial transceivers (up to 3.125 Gbps) and PCIe endpoints, enabling advanced bridging and serial connectivity applications. Typical applications include automotive infotainment systems, industrial automation controllers, consumer electronics bridging, and high-speed data acquisition. The 296 I/Os and 4.71 Mbit memory make it ideal for video processing, motor control, and protocol conversion. The -3 speed grade ensures timing closure for demanding designs. When designing with this FPGA, careful attention to power supply decoupling is essential. Use multiple 100nF and 10uF capacitors near the VCCINT, VCCAUX, and VCCO pins to minimize noise. Additionally, configure the device's I/O standards to match the external interface voltages to prevent damage and ensure signal integrity.

XC6SLX16-2CPG196C

XC6SLX16-2CPG196C - Spartan-6 LX 375 MHz FPGA | AMD

AMD/Xilinx XC6SLX16-2CPG196C is a Spartan-6 LX field-programmable gate array with 14,579 logic cells, 106 user I/Os, and a maximum stated operating frequency of 375 MHz, supplied in a 196-ball CSBGA package. The device operates from a 1.14 V to 1.26 V core-supply range and is built on 45 nm CMOS technology. It combines programmable logic, block RAM, digital clock managers, and PLL resources in a cost-sensitive FPGA platform for industrial and embedded systems. A field-programmable gate array is a semiconductor device whose digital behavior is configured through a programmable bitstream rather than a fixed circuit layout. Within the product hierarchy, an FPGA is a programmable logic device and semiconductor, while the Spartan-6 LX family combines configurable logic blocks and dedicated resources for parallel processing, control, signal generation, and interface bridging. The XC6SLX16-2CPG196C provides 14,579 logic cells, 106 user I/Os, 375 MHz stated operating performance, and 667 MHz internal frequency according to the verified product listings. Its 196-ball CSBGA footprint measures 19 mm by 19 mm with a 0.80 mm ball pitch. The commercial-temperature suffix C corresponds to the listed 0 °C to 85 °C operating range, while the -2 suffix identifies the device speed grade. Spartan-6 devices use configurable logic and dedicated resources to implement control logic, parallel data processing, memory-intensive functions, and communication bridges. The -2 grade provides a practical balance between processing performance and cost, making the LX16 suitable for cost-sensitive designs that need more integration than a small programmable logic device but do not require a large premium FPGA. Typical uses include industrial automation, motor-control interfaces, machine-vision pre-processing, sensor acquisition, communication bridging, embedded control, and high-volume consumer equipment. The combination of 106 I/Os and 14,579 logic cells allows multiple interfaces and control domains to be consolidated on one programmable device while retaining field-upgradeable behavior. Designers should treat the 1.14 V to 1.26 V core supply as a dedicated power domain, follow AMD Spartan-6 decoupling and configuration recommendations, and verify the exact CPG196 pinout and ball assignments before layout. Thermal, signal-integrity, and configuration-boot requirements must be checked against the applicable Spartan-6 hardware documentation rather than inferred solely from the distributor summary.

XC6SLX16-2CPG196I

XC6SLX16-2CPG196I - 14k Logic Cells Spartan-6 FPGA | AMD

The AMD (Xilinx) XC6SLX16-2CPG196I is a Spartan-6 LX FPGA built on a 45 nm CMOS process, delivering 14,579 logic cells with 106 user I/Os in a 196-ball 8 mm × 8 mm CSBGA (TFBGA) package, with 576 Kbit of embedded block RAM and integrated DSP slices. The “-2” speed grade and industrial-grade (-40 °C to +100 °C) “I” temperature suffix indicate a -2 speed/performance tier intended for industrial-temperature environments. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit built from configurable logic blocks (CLBs), programmable routing, and dedicated hardware resources such as block RAM, multipliers/DSP slices, and clock management tiles (DCMs/PLLs). The Spartan-6 LX series sits in the low-power, low-cost tier of the AMD/Xilinx product hierarchy: FPGA -> programmable logic -> logic IC -> integrated circuit. Spartan-6 LX devices target high-volume, cost-sensitive bridging, control, and signal-processing applications that need the parallelism and reconfigurability of an FPGA without the cost of a Virtex-class device. Key features of the XC6SLX16-2CPG196I include: 14,579 logic cells (~2,300 logic slices), 106 maximum user I/Os (some version/board use this number; package allows up to 106), 576 Kbit (72 Kbyte) of block RAM, 32 DSP48A1 slices, four DCMs and two PLLs for clock management, on-chip memory controllers (MCB) for DDR/DDR2/LPDDR, and a 1.2 V core supply with dedicated high-performance/low-power transceiverless I/O banks. The device is implemented on 45 nm process technology, delivering low static and dynamic power versus previous Spartan generations. The -2 speed grade is the mid-tier in the Spartan-6 family and balances Fmax and power for typical industrial designs. Architecturally, the XC6SLX16-2CPG196I uses a register-rich, columnar LUT-6 architecture with dedicated carry chains, distributed RAM/SRL16 shift-register logic in each CLB, and a hard PCIe endpoint block on higher-density siblings (note: LX16 does not include the integrated PCIe block; it is on LX45+). Multiple I/O standards (LVCMOS, LVDS, HSTL, SSTL) are supported with per-bank reference voltages, and the package is lead-free (Pb-free) RoHS-compliant. The 8 × 8 mm CSBGA package supports high-density board layouts in space-constrained designs. Typical applications include industrial motor control and factory automation, automotive infotainment displays and driver-assistance modules, consumer video bridging (HDMI/LVDS), low-cost software-defined radio front-ends, embedded vision pre-processing, and communication backplane bridging. The 576 Kbit of block RAM and 32 DSP slices make the LX16 well suited to small FIR/IIR filters, modest FFT engines, sensor-fusion pre-processing, and glue-logic aggregation. Pairing with a small external SPI flash for configuration memory keeps the BOM lean. When designing with this FPGA, verify that the -2 speed grade meets your target Fmax for the design floorplan, ensure JTAG and DONE pull-up values match the Spartan-6 configuration user guide, and check I/O-bank voltage compatibility before mixing 3.3 V peripherals with 1.2 V core logic. Note: the LX16 does not include the integrated PCIe block; use LX45/LX75/LX100/LX150 if PCIe hard IP is required.
