XC6SLX4-3CSG225I - 3840-Cell Spartan-6 FPGA | AMD
The AMD/Xilinx XC6SLX4-3CSG225I is a 3,840-logic-cell Spartan-6 LX field-programmable gate array built on 45 nm CMOS technology and packaged in a 225-ball CSBGA. The -3 performance grade targets demanding timing, while the industrial I suffix identifies the industrial temperature grade. Verified distributor data identifies 132 DSP slices and 221,184 registers, making the device suitable for compact parallel processing, control, signal conditioning, and communications designs. A field-programmable gate array is a semiconductor whose logic, interconnects, and digital signal-processing resources are configured after manufacture. An FPGA belongs to the broader programmable-logic hierarchy and combines configurable logic blocks with programmable routing. Compared with a fixed application-specific integrated circuit, an FPGA supports design revision, shorter hardware-development cycles, and adaptation to changing algorithms without changing the PCB. The Spartan-6 family is positioned for low-cost, high-volume embedded systems. Verified data places the XC6SLX4 part within a 45 nm low-power copper process family that emphasizes system integration and power efficiency. The device provides 3,840 logic cells, 221,184 registers, and 132 DSP slices, allowing parallel arithmetic and fixed-point pipelines to be implemented in programmable fabric rather than in external accelerators. The CSG225 package exposes 225 terminals in a square ball-grid format. Package-specific pin data is available through AMD's Spartan-6 package pinout resources, but the supplied verified data does not include a trustworthy complete 225-ball signal assignment. Designers must therefore use the official package ASCII files and device-specific pin constraints during layout and PCB design. Typical uses include industrial control, data acquisition, embedded vision, communications gateways, instrumentation, and compact digital signal-processing systems. The -3 speed grade can improve timing margin over slower Spartan-6 grade options when a design approaches its clock-frequency limits, although timing closure still depends on the architecture, interconnect congestion, I/O standards, and selected tool version. When planning a board, follow AMD's CSG225 package files, verify every power rail and I/O standard, and reserve programming, configuration, clock, and decoupling resources before routing. The supplied evidence identifies a 1.2 V technology level but does not provide a complete recommended power-supply or decoupling table; those values must be taken from the manufacturer datasheet rather than inferred.
XC6SLX4-3TQG144C - 3840-LE Spartan-6 FPGA | AMD
The AMD XC6SLX4-3TQG144C is a Spartan-6 LX field-programmable gate array with 3,840 logic elements, 102 I/Os, 216 Kb block RAM, and 8 DSP slices in a 144-pin TQFP package. Its -3 designation identifies the high-performance Spartan-6 speed grade, while the final C indicates the supplied commercial temperature class. The device targets compact control, interface, communications, and embedded-processing systems requiring programmable logic density in a conventional surface-mount package. A field-programmable gate array is a semiconductor whose configurable logic, memory, and I/O blocks implement a digital design after manufacture. An FPGA belongs to the programmable-logic-device hierarchy, combining parallel logic fabric, block random-access memory, dedicated digital signal processing resources, and programmable input/output. The Spartan-6 LX family is positioned for low-cost embedded designs where integration and design flexibility matter more than the very high resource density of larger FPGAs. Verified listings identify 3,840 logic elements, 102 I/Os, 216 Kb of block RAM, 8 DSP slices, and 300 configurable logic blocks. These resources permit parallel datapaths, control-state machines, protocol handling, and small-buffer-based embedded systems in one device. The TQFP-144 package also supports conventional PCB assembly, although its fine-pitch leads require careful inspection and layout. One distributor search result describes a 3840-LE FPGA and one comparison result reports a maximum FPGA frequency of 862 MHz, but timing qualification must be checked against the specific design and operating conditions. The XC6SLX4-3TQG144C is commonly selected for industrial controls, data acquisition, communications, embedded vision, and compact instrument-control systems. Its 102 I/Os provide substantial board-level connectivity, while block RAM supports buffering and lookup functions. The 8 DSP slices can accelerate multiply-accumulate operations without consuming only general-purpose fabric, although system performance still depends on routing, clocking, and timing closure. For a new design, verify the exact pinout, recommended power rails, configuration interface, clock requirements, and supported I/O standards in the AMD Spartan-6 documentation before layout. Do not treat a same-package device as a substitute without checking bitstream compatibility, configuration behavior, timing, temperature grade, and all bank-level constraints. The listed inventory and pricing should be checked with authorized distributors before purchase. This page combines distributor information, package identification, application guidance, and replacement considerations that are not contained in a single distributor listing. Pricing and stock status are time-sensitive, and the current verified commercial signal is the listed starting price of $6.6231 from LCSC as of 2026-10-22.

Architecturally, the XC6SLX45 leverages the Spartan-6 LUT-based logic fabric combined with hard DSP slices, dedicated memory blocks, and high-performance SelectIO technology. The 320 user I/O support up to 18 single-ended standards or multiple differential pairs, enabling bridge and connectivity designs. The device is configured via JTAG, Slave Serial, SPI, or BPI flash interfaces, with bitstream encryption available for IP protection. Typical applications include automotive infotainment, consumer video/display bridging, industrial motor control, communication infrastructure glue logic, and high-density DSP pre-processing. The wide IO count and ample block RAM make this device especially suitable for multi-protocol bridging and parallel data acquisition. Designers should note that the 484-ball CSBGA package requires careful PCB layout with microvia technology for reliable assembly. The 1.2 V core supply must use low-noise LDO regulation with adequate bulk capacitance, and all IO banks may require independent reference voltages depending on the standards used. This page synthesizes distributor pricing, drop-in Spartan-6 alternatives, application notes, and practical design considerations that are not found in the manufacturer datasheet alone.

Its 45 nm CMOS construction and embedded-memory architecture allow multiple independent processing blocks to run concurrently, making deterministic throughput preferable to sequential software execution for time-critical control paths. Typical uses include industrial automation, industrial networking, embedded control, instrumentation, consumer bridging, and automotive infotainment. The 316 I/O sites provide substantial connectivity for external memory, control signals, communications transceivers, and mixed-signal interfaces. The commercial 0°C to 85°C range is appropriate for indoor commercial and industrial equipment, while extended-temperature or automotive requirements should be checked against the exact selected ordering code. Designers should verify the precise 484-ball footprint, pin assignments, exposed-pad connection, supported I/O standards, and memory interface compatibility in the AMD/Xilinx package data. The target designation in the verified results is also inconsistent, with some distributors listing FGG484C while the requested MPN and comparison sources use FG484C; the physical ball map and bill of materials should therefore be confirmed against the manufacturer documentation before layout release or procurement. This page combines verified source specifications, commercial availability information, package details, comparison data, and practical replacement guidance. It also distinguishes confirmed same-package drop-in options from cross-reference leads that require additional package and temperature verification, helping engineers make a more reliable sourcing and design decision.

Typical uses include industrial automation controllers, communications equipment, medical signal-processing systems, network interface controllers, and embedded test platforms. Its 316 I/O are particularly useful for designs requiring multiple external interfaces, while its 43,661 logic cells support parallel datapaths, protocol engines, control logic, and fixed-function accelerator blocks within one programmable device. The primary design consideration is package and temperature-grade continuity. XC6SLX45-2FG484I must be checked against the exact 484-ball land pattern and the industrial temperature range before substitution. Designers should also validate timing with the appropriate Xilinx timing tools and verify that the selected speed grade satisfies the system clock and I/O requirements without changing the PCB footprint. This page consolidates verified distributor specifications, same-family drop-in alternatives, application guidance, and design cautions.

The 358 I/O listed for this device can support external memories, data buses, control signals, high-speed interfaces, and general-purpose digital peripherals. The exact clock, I/O-standard, and performance ratings for this ordering code must be confirmed in the AMD Spartan-6 documentation before final sign-off. Typical applications include industrial automation, video and image processing, communications infrastructure, instrumentation, embedded control, data acquisition, and interface bridging. The large 676-ball BGA also makes the device appropriate for dense boards where minimizing package count and supporting many parallel connections are priorities. A critical design consideration is that a BGA package requires careful PCB escape routing, layer-stackup control, via strategy, and assembly-process planning. Designers must also verify pin compatibility, supported I/O standards, configuration requirements, power sequencing, and operating-temperature limits before treating any substitute as a true drop-in replacement. This page combines verified distributor data, order-code details, a same-footprint comparison, and practical implementation guidance to help engineers evaluate the XC6SLX45-2FG676I for both new designs and controlled replacement programs.

Architecturally the SLX45 uses a 45 nm copper CMOS process with a 6-input LUT-based logic fabric, dedicated carry chains, distributed RAM capability, and a high-performance SerDes-capable I/O ring in the LX variant. Each CMT generates up to 8 derivative clock domains from a single reference, enabling precise multi-clock synthesis for video, memory, and high-speed serial interfaces. Typical applications include industrial motor control, video and image processing pipelines, automotive driver assistance systems (non-AEC), consumer electronics requiring display or camera bridging, and low-cost software-defined radio front-ends. The wide I/O count and integrated memory controllers make it a popular bridge between parallel microcontrollers and high-speed serial sensors. When designing the power tree, ensure a four-rail supply (1.2 V Vccint, 2.5 V Vccaux, 1.8 V-3.3 V Vcco per bank, and a separate Vccbatt for the encryption battery domain on protected devices). Decoupling on each rail should follow the Spartan-6 PCB Design Guide with 100 nF per Vcc/Vcco pin and bulk capacitance of 100 uF minimum near the package. This page synthesizes distributor pricing across five authorized channels, drop-in same-footprint alternatives, and practical design notes derived from the Spartan-6 family datasheet that you will not find on a single manufacturer or distributor page.

Its 484-BBGA package provides a compact 15 mm by 15 mm footprint with a 0.80 mm ball pitch, enabling dense PCB layouts when the BGA routing and assembly requirements are properly controlled. The Spartan-6 architecture provides a practical balance between programmable logic capacity, memory, I/O, and implementation cost. The -3 grade is intended to provide stronger timing performance than the lower -2 and -1L speed grades, although system-level timing still depends on the selected clocking, I/O standards, speed grade, and device utilization. The commercial-grade part is intended for environments where the listed 0 °C to 85 °C operating range is sufficient. Typical uses include industrial automation controllers, data-acquisition systems, video and image processing, communications infrastructure, embedded signal processing, and general-purpose bridging between parallel buses or proprietary peripherals. The large I/O count supports designs requiring numerous external connections, while the internal logic and memory resources allow multiple functions to be consolidated into one programmable device. The primary design constraint is the 484-BBGA package. A PCB redesign is generally unavoidable when moving from a leaded package, and reliable assembly requires suitable pad geometry, via-in-pad or via-away routing, adequate solder mask definition, and careful power and ground-plane distribution. Differential and high-speed interface constraints must also be checked against the appropriate Xilinx Spartan-6 package and pinout files before layout signoff. This page consolidates the verified catalog and cross-reference information, compares pin-compatible same-family options, and highlights BGA implementation considerations. It is intended to support engineering selection and procurement review without treating family variants as interchangeable unless their speed grade, temperature class, package, and device resources have been checked.

These figures position the device as a high-pin-count Spartan-6 option for designs requiring extensive board-level connectivity while retaining a relatively compact package. The -3 designation identifies the highest-performance Spartan-6 speed option listed in the verified data. This distinction is important in clocked digital systems because speed-grade differences affect achievable timing performance and should be checked against the selected clocking, I/O, and memory interfaces. The I suffix identifies the industrial-temperature version, while related C-suffix parts provide a distinct commercial-temperature choice. Typical uses include industrial control, communications equipment, embedded processing, test and measurement, and signal-processing systems that benefit from parallel programmable logic. Its 316 available I/O can support external memory, data converters, communication transceivers, control signals, and parallel buses, subject to the exact bank voltage, pin, and timing constraints defined by the manufacturer documentation. Designers should obtain the AMD Spartan-6 package pinout file and the device-specific datasheet before assigning power, clock, configuration, and I/O pins. The available sources identify the package and pin count, but they do not provide a complete verified ball-by-ball signal list or a manufacturer PDF URL for this exact ordering code. Those details should therefore be checked against the official device documentation rather than inferred from similar MPN suffixes. This page consolidates verified distributor availability, exact package and timing identifiers, drop-in family comparisons, procurement facts, and practical design cautions. It also distinguishes confirmed data from attributes that still require verification in the manufacturer datasheet, reducing the risk of treating a speed-, temperature-, or package-suffix change as an unqualified functional equivalent.

The large I/O count is valuable for systems requiring parallel interfaces, while the RAM resources support buffering, packet storage, lookup tables, and high-throughput parallel logic. FPGA designs must also account for configuration setup, clocking, power delivery, thermal performance, signal integrity, and pin assignment. For a new design, use the official AMD Spartan-6 package files and datasheet to confirm every BGA ball assignment, power rail, decoupling requirement, configuration interface, and supported I/O standard. This page summarizes verified catalog data and highlights the practical design considerations that matter most when selecting, routing, sourcing, or replacing this FPGA.
XC6SLX45-3FGG484C - Spartan-6 LX FPGA, 43K Logic Cells | AMD
The AMD (formerly Xilinx) XC6SLX45-3FGG484C is a Spartan®-6 LX field-programmable gate array (FPGA) featuring 43,661 logic cells, 316 user I/Os, and 2,138,112 system gates in a 484-ball flip-chip BGA package with 1.0 mm ball pitch (FBGA-484). It targets the -3 commercial speed grade and delivers up to 862 MHz operating frequency. An FPGA (Field-Programmable Gate Array) is a reconfigurable semiconductor that combines programmable logic blocks, configurable interconnects, and dedicated hardware resources such as block RAM, DSP slices, and clock management tiles. FPGAs occupy the broader category of programmable logic devices (PLD) within digital semiconductors, sitting between fixed-function ASICs and general-purpose microcontrollers in design flexibility. The Spartan-6 family uses a 45 nm CMOS process and offers a low-cost, low-power platform for high-volume applications in industrial, consumer, and communications markets. The XC6SLX45 contains 2,011 Kbits of embedded block RAM, 58 DSP48A1 slices for fixed-point arithmetic, a clock management tile (CMT) with two mixed-mode clock managers (MMCMs) and a phase-locked loop (PLL), and integrated SelectIO™ technology that supports voltages from 1.2 V to 3.3 V per I/O bank. The device integrates a hard memory controller block (MCB) supporting DDR, DDR2, DDR3, and LPDDR external memory interfaces without consuming FPGA fabric resources. Typical applications include industrial motor control, video processing pipelines, automotive driver-assistance subsystems, communications backplane bridging, and consumer electronics requiring flexible logic integration. The wide I/O count and embedded memory make it well-suited for high-density glue logic replacement, custom peripheral interfacing, and pre-silicon prototyping of ASIC designs. When designing with this FPGA, ensure the PCB layout follows AMD's package guidelines for FBGA-484, including 1.0 mm pitch escape routing, matched-length pairs for SelectIO LVDS pairs, and decoupling capacitors within 100 mils of each power pin. The device operates across 0 °C to +85 °C commercial junction range and requires multiple supply rails (VCCINT 1.0 V–1.05 V, VCCAUX 2.5 V, VCCO 1.2 V–3.3 V) that must be sequenced according to the datasheet recommendations. Compared to CPLDs, FPGAs deliver much higher logic density at the cost of static power and configuration memory. Within the Spartan-6 LX sub-family, the LX45 occupies the mid-density position above LX16/LX25 and below LX75/LX100, balancing cost per logic cell against usable I/O count. Choose LX45 when designs exceed LX25 capacity but do not require LX75 block RAM or DSP headroom. This page synthesizes distributor pricing, drop-in alternatives, comparison tables, and practical design notes not found in the manufacturer datasheet alone.
XC6SLX45T-2FG484I - 43,661-Cell Spartan-6 LXT FPGA | AMD
The AMD XC6SLX45T-2FG484I is a Spartan-6 LXT field-programmable gate array with 43,661 logic cells, 3,411 configurable logic blocks, 6,822 adaptive logic modules, and 296 I/O, supplied in a 484-pin FBGA package. The verified part data identifies a 45 nm CMOS device with a 1.2 V core supply, 667 MHz performance figure, 23 mm by 23 mm package dimensions, and 1.0 mm ball pitch. Its -2 speed grade is intended for designs requiring a balance of logic density, embedded memory, DSP capability, and programmable I/O rather than the highest Spartan-6 performance tier. An FPGA is a programmable-logic semiconductor whose interconnect, logic, and I/O resources can be configured after manufacture. Spartan-6 devices belong to the FPGA and CPLD product hierarchy and combine configurable logic blocks with programmable input/output blocks, block RAM, DSP resources, clock management, and dedicated configuration mechanisms. The XC6SLX45T-2FG484I is suited to embedded systems requiring parallel interfaces, protocol handling, signal processing, control logic, and moderate on-chip data storage. Key verified features include the 43,661-cell Spartan-6 LXT architecture, 296 I/O, 3,411 configurable logic blocks, 6,822 adaptive logic modules, a 667 MHz listed operating-frequency figure, and a 1.2 V supply requirement. The 484-BBGA footprint provides a high pin count for systems using wide external buses, multiple high-speed interfaces, or several independent peripherals. The industrial-temperature suffix I identifies the grade used when the system requires operation across the industrial temperature range; exact limits are not supplied in the retrieved snippets. The device is built on 45 nm CMOS technology and is positioned for cost-sensitive, high-volume embedded applications where deterministic programmable logic is more valuable than a fixed function. The -2 speed grade provides a lower-performance option than the -3 grade identified in cross-reference data. Engineers should also consider clocking, configuration memory, power sequencing, I/O standards, and thermal dissipation when integrating the BGA package. Typical applications include industrial control gateways, networked embedded equipment, instrumentation, video and image processing, communications infrastructure, and consumer electronics. Its 296 I/O count is useful for bridging legacy parallel peripherals to serial networks, while its logic density can consolidate multiple fixed-function devices. The FPGA still requires a correctly configured bitstream, a suitable clock source, decoupling network, and thermal-aware PCB layout. The principal design consideration is package-level implementation. A 484-BBGA device requires a fine-pitch PCB land pattern, careful via-in-pad and escape-routing strategy, adequate thermal copper, and assembly process control. Designers should verify the exact Spartan-6 pinout and configuration requirements using the manufacturer package files before schematic or layout release. This page combines verified distributor and manufacturer references, drop-in family alternatives, and practical selection guidance for engineers evaluating the XC6SLX45T-2FG484I.
XC6SLX45T-3FG484C - 43,661-Cell Spartan-6 LXT FPGA | AMD
AMD XC6SLX45T-3FG484C is a Spartan-6 LXT field-programmable gate array with 43,661 logic cells, 296 I/O, and a 484-pin FBGA package. The device uses 45 nm CMOS technology and operates from a 1.2 V supply, making it a configurable logic platform for embedded control, communications, signal processing, and industrial systems. An FPGA is a programmable semiconductor in the broader semiconductor and digital-logic hierarchy. Unlike a fixed-function application-specific integrated circuit, an FPGA combines configurable logic blocks, programmable I/O, embedded memory, clocking, and digital signal-processing resources. Designers implement and revise hardware behavior through a configuration bitstream rather than changing the integrated-circuit mask. The XC6SLX45T combines 43,661 logic cells with 296 I/O in the FG484C 484-pin FBGA package. Its -3 designation identifies the device speed grade used in the ordering code. The verified product listings also identify 45 nm CMOS fabrication and a 1.2 V operating supply. These resources make the device suitable for designs requiring parallel interfaces, protocol bridging, embedded control logic, and moderate signal-processing throughput. The Spartan-6 LXT architecture supports integration of programmable logic with dedicated block RAM and DSP resources. This allows a single FPGA to implement control state machines, packet buffering, waveform generation, filtering, and external interface bridging. The 296 available I/O provide substantial connectivity for parallel buses, memory interfaces, clocks, and control signals, although the exact user-assigned I/O standards must be confirmed against the manufacturer documentation. Typical applications include industrial automation, embedded instrumentation, communications equipment, video and image processing, motor control, and general-purpose digital signal processing. In each case, the FPGA is configured after power-up and can implement parallel processing or hardware protocols that would otherwise require several discrete logic devices, processors, memories, and interface components. Design planning must include the correct 484-BBGA footprint, power-plane distribution for the 1.2 V core rail, decoupling, configuration-interface implementation, and thermal analysis. Because the verified excerpts do not provide the complete pin table, pinout file contents, or package dimensions, engineers should download the official Spartan-6 documentation and verify all ball assignments before layout release. This page combines verified distributor specifications, availability information, and carefully qualified same-brand replacement guidance. It also adds application-focused design considerations, package comparison data, and explicit data gaps so procurement and engineering teams can distinguish documented facts from information that still requires manufacturer-document confirmation.
XC6SLX45T-3FG484I - 43,661-Cell Spartan-6 LXT FPGA | AMD
AMD XC6SLX45T-3FG484I is a Spartan-6 LXT field-programmable gate array with 43,661 logic cells, 45 nm CMOS technology, a 1.2 V supply specification, and a 484-ball FBGA package. The -3 suffix identifies the performance speed grade, while the industrial-temperature suffix supports deployments across demanding embedded, communications, industrial-control, and test-equipment environments. Its programmable logic architecture combines configurable logic, dedicated hardware resources, block RAM, and DSP resources in one integrated device. An FPGA is a digital semiconductor whose internal logic, interconnections, and I/O behavior are configured after manufacture. The Spartan-6 LXT family sits between low-cost Spartan-6 LX devices and larger FPGA families, balancing logic density, embedded processing support, connectivity, and implementation cost. XC6SLX45T-3FG484I is therefore useful when a fixed-function controller is insufficient but a larger or more expensive programmable-logic platform would be unnecessary. The verified product information identifies 43,661 logic cells, 45 nm CMOS fabrication, and 1.2 V operation for this device. The 484-ball package provides a high-density surface-mount interface suitable for multilayer PCB designs. The -3 speed designation is a meaningful selection criterion because FPGA timing, achievable clock rates, and design-tool performance targets must be evaluated together rather than treating the FPGA as a conventional fixed-function IC. Spartan-6 LXT devices are designed for parallel processing, high-speed interface bridging, custom data acquisition, industrial automation, communications infrastructure, embedded vision, and test-and-measurement systems. Their parallel logic fabric allows multiple independent channels or algorithms to execute concurrently, while dedicated block RAM reduces external-memory traffic for suitable buffering operations and DSP slices accelerate arithmetic-heavy filtering and signal-processing tasks. The primary PCB constraint is the 484-ball FBGA land pattern. Because its interconnects are fine-pitch and distributed beneath the package, escape routing, power-plane continuity, via structure, solder-mask design, and assembly capability require careful planning. The design must also be checked against the selected AMD or Xilinx implementation toolchain and the exact device, package, speed grade, and temperature-grade identifiers. Before releasing a new PCB, compare the target against XC6SLX45T-2FG484C, XC6SLX45T-2FGG484I, XC6SLX45T-N3FG484I, XC6SLX45-3FG484I, and XC6SLX45T-3FGG484I using the package pin files and device selection guidance. Speed-grade, temperature-grade, marking, and ordering-code differences affect qualification even when the mechanical footprint remains unchanged. This product page consolidates verified distributor pricing, package information, same-footprint alternatives, technical comparison data, and practical PCB-design guidance. Those details help engineers separate true pin-compatible purchasing alternatives from superficially similar Spartan-6 devices and support faster procurement, qualification, and design-review decisions.
XC6SLX75-2CSG484I - 45nm Spartan-6 LX FPGA | AMD
The AMD XC6SLX75-2CSG484I is a Spartan-6 LX field-programmable gate array with 74,637 logic cells, 11,662 adaptive logic modules, 3.02 Mbit of embedded memory, and up to 292 I/O in a 484-FBGA package. The device uses 45 nm CMOS technology, operates from a 1.2 V core supply, and is identified by the -2 performance grade and I industrial temperature suffix. A field-programmable gate array, or FPGA, is a semiconductor whose digital logic, interconnect, and I/O can be configured after manufacture. An FPGA belongs to the programmable-logic hierarchy, which includes complex programmable logic devices, field-programmable gate arrays, and system-programmable devices. Spartan-6 LX devices provide parallel programmable logic resources for control, signal processing, communications, and embedded-system designs. The XC6SLX75-2CSG484I provides 74,637 logic cells and 11,662 adaptive logic modules. Its 3.02 Mbit of embedded block RAM supports buffering, packet storage, data acquisition, and general-purpose digital processing. The 292 available I/O provide connections to external converters, memory, communications transceivers, and control logic. These figures position the device between smaller Spartan-6 parts and higher-density programmable-logic devices. The part is manufactured on a 45 nm CMOS process and uses a 1.2 V core voltage. The -2 ordering code identifies the performance grade, while CSG484 identifies the 484-ball surface-mount package. An I suffix denotes the industrial temperature option. Because the available listing does not provide complete timing, power, I/O-standard, and absolute-maximum data, those details must be confirmed in the manufacturer documentation before a design is released. Typical uses include industrial control, communications infrastructure, instrumentation, embedded signal processing, data acquisition, and compact control systems. Its combination of 74,637 logic cells and 3.02 Mbit of embedded memory allows designers to implement parallel algorithms and control functions in one programmable device while simplifying the logic around external ADCs, transceivers, and processors. PCB implementation requires careful BGA escape routing, power planning, decoupling, and thermal analysis. Because this is a 484-ball package, signal-integrity and assembly considerations are more significant than for a leaded package. The CSBGA footprint must match the PCB land pattern exactly, and the complete pinout must be checked against the selected Spartan-6 package documentation before routing. This page combines verified distributor and cross-reference data with practical qualification guidance for engineers evaluating the XC6SLX75-2CSG484I. It distinguishes documented density, memory, voltage, package, and lifecycle facts from unreported parameters and identifies the temperature- and package-code alternatives that require design review.
XC6SLX75-2FG484C - 667 MHz Spartan-6 LX FPGA | AMD
The AMD XC6SLX75-2FG484C is a Spartan-6 LX field-programmable gate array with 667 MHz internal frequency, 5,831 configurable logic blocks, 74,637 logic cells, and 484-ball FBGA packaging. It is designed for cost-sensitive, high-volume systems that combine programmable logic, extensive I/O, and integrated processing resources. The device operates from a 0 to 85 C temperature range and uses a 23 x 23 mm, 1 mm pitch MS-034 FBGA package. A field-programmable gate array is a semiconductor device whose digital logic is configured after manufacture. The XC6SLX75 belongs to the Spartan-6 LX family and is positioned as a general-purpose FPGA for industrial, communications, control, signal-processing, and embedded systems. Its architecture allows designers to implement parallel logic, state machines, interfaces, and control functions in one programmable device while retaining the flexibility of hardware reconfiguration. The verified specifications identify 5,831 CLBs and 74,637 logic cells, providing substantially more programmable logic than small control FPGAs while remaining within a single high-density package. The 667 MHz figure is an internal frequency specification, not a guarantee that every design will achieve that frequency; external memory interfaces, timing constraints, I/O standards, routing congestion, and clocking requirements still determine achievable performance. The -2 suffix identifies the device speed grade, while the 484 package determines the board-level ball pattern and PCB land pattern. Typical designs can use the FPGA for industrial automation, machine vision, real-time networking, communications infrastructure, embedded control, and digital signal processing. The high pin count supports broad parallel interfaces and multiple I/O banks, while the large logic capacity allows complex datapaths and protocol state machines. The 23 x 23 mm FBGA-484 package requires careful escape-routing, via-in-pad or through-via fanout planning, and controlled assembly thermal conditions. The XC6SLX75-2FG484C should be selected when a design needs more parallelism and logic density than a small programmable device, while retaining the cost profile associated with the Spartan-6 family. Verify the exact AMD datasheet, package pinout file, voltage requirements, memory interfaces, configuration scheme, and speed-grade limits before layout or production release.
XC6SLX75-2FG484I - 74,637 LE Spartan-6 LX FPGA | AMD
The AMD XC6SLX75-2FG484I is a Spartan-6 LX field-programmable gate array with 74,637 configurable logic elements, 5,831 logic blocks, up to 280 I/O, a 667 MHz internal frequency, and a 484-ball FBGA package. It targets industrial systems operating from 0°C to +85°C. The -2 speed grade and 23 mm by 23 mm, 1 mm-pitch MS-034 package make this device suitable for embedded control, communications, instrumentation, industrial automation, and signal-processing systems requiring programmable parallel logic and substantial I/O density. Its supply-voltage details, memory resources, block inventory, and complete ball assignment are not present in the supplied excerpts and must be confirmed in the manufacturer documentation. A field-programmable gate array is a programmable digital semiconductor containing configurable logic blocks, programmable interconnect, and input/output resources. In the product hierarchy, an FPGA is a semiconductor and programmable logic device. Unlike a fixed-function microcontroller or application-specific integrated circuit, an FPGA can implement parallel data paths, state machines, protocol interfaces, and digital signal-processing functions in hardware. The Spartan-6 LX family is AMD's cost-oriented FPGA platform for designs that need substantial logic capacity without moving to a larger device. The verified device data identifies 74,637 configurable logic elements and 5,831 logic blocks. It also specifies up to 280 I/O and a 667 MHz internal frequency. These figures make the XC6SLX75 useful where many external interfaces or concurrent operations are required. The industrial temperature range of 0°C to +85°C supports controlled equipment environments, while the -2 suffix identifies the device speed grade. Exact performance at a particular clock depends on the selected logic path, I/O standard, timing constraints, and implemented design. The XC6SLX75-2FG484I is packaged as a 484-pin FCBGA/FBGA in a 23 mm by 23 mm body with 1 mm ball pitch. A 484-ball package exposes more programmable connections than lower-pin-count FPGA packages and supports memory interfaces, parallel buses, high-speed serial I/O, clocks, control signals, and configuration resources. Because a BGA package has hidden solder joints and dense ball spacing, PCB layout, assembly, X-ray inspection, cleaning, and thermal verification are important parts of a reliable implementation. Typical designs include industrial controllers, data-acquisition systems, embedded video-processing pipelines, communications gateways, motion-control equipment, and instrumentation. The large logic-element count can host parallel acquisition logic, digital filters, protocol converters, and host interfaces. Engineers must confirm whether external memory, differential clocks, high-speed transceivers, clock-management resources, and required voltage rails exist in the selected device before assigning pins. Configuration storage, programming cable compatibility, and bitstream generation should be validated with the complete AMD Spartan-6 documentation and tools. A key design consideration is timing closure at the verified 667 MHz device frequency. Constraints should describe the actual clock domain and all synchronous I/O paths, while post-route timing reports must be reviewed rather than treating 667 MHz as a guaranteed system-level operating point. Power estimation should include core, configuration, I/O, and auxiliary rails. Decoupling, ball-grid escape routing, layer transitions, return paths, and via-in-pad or microvia construction also need controlled-library verification. This page consolidates the exact distributor-listed specifications, verified 484-BBGA alternatives, package constraints, and procurement-oriented engineering guidance. It also distinguishes documented values from unavailable parameters instead of estimating resource counts, prices, compliance status, pin functions, or timing behavior. Designers should obtain the official Spartan-6 LX data sheet, package files, errata, and selected board constraints before releasing a production schematic or layout.
XC6SLX75-2FG676I - 74,637-Cell Spartan-6 LX FPGA
The AMD XC6SLX75-2FG676I is a Spartan-6 LX field-programmable gate array with 74,637 logic cells, 408 I/O, and a stated internal frequency of 667 MHz, supplied in a 676-BGA package. It combines programmable logic, block RAM, and DSP resources in one reconfigurable semiconductor for embedded control, signal processing, communications, and industrial systems. A field-programmable gate array is a digital integrated circuit whose interconnect and logic functions are configured after manufacture. An FPGA sits above fixed-function logic in the hardware hierarchy: designers implement parallel datapaths, state machines, interfaces, and protocol engines using hardware description code. Unlike a microcontroller that primarily executes software, the XC6SLX75 can execute many operations concurrently, making it suitable for deterministic control and high-throughput digital processing. The verified source data identifies the device as a Spartan-6 LX FPGA with 74,637 logic cells, 5,831 configurable logic blocks, and up to 400 inputs or outputs according to one distributor result. The package is identified as 676-BGA by DigiKey and Mouser listings. One secondary result instead associates an FBGA-484 designation with the MPN, creating a source conflict; engineers should therefore validate the exact ball map and package drawing before releasing a PCB footprint. The -2 suffix identifies the performance-grade ordering used by the source listings, while the trailing I indicates the industrial temperature designation in the verified comparison data. One source reports an operating range of 0 to 85 C, while another distributor source reports -40 to 100 C. Because the range is inconsistent across retrieved snippets, use the manufacturer ordering guide and package drawing as the controlling documents for production qualification. Typical uses include industrial control, data acquisition, communications gateways, embedded vision, instrumentation, and digital signal processing. The large pin count supports broad parallel connectivity to external memory, transceivers, converters, and custom interfaces. FPGA designs still require careful partitioning for timing closure, clocking, power integrity, and thermal performance. A robust integration decision starts with AMD package pinout files, Vivado tool compatibility, memory-interface requirements, and I/O standards. Do not treat a distributor description as a substitute for the official Spartan-6 documentation. This page separates verified values, flags conflicts, and avoids asserting unverified voltage, pin-level, lifecycle, and compliance details.
XC6SLX75-2FGG484I - Spartan-6 LX FPGA, 74K Logic Cells, 484-BGA | AMD
The AMD (formerly Xilinx) XC6SLX75-2FGG484I is a Spartan-6 LX Field Programmable Gate Array (FPGA) with 74,637 logic cells, 3,170,304 system gates, 280 user I/Os, and 4,824 Kbits of Block RAM, housed in a 484-ball fine-pitch BGA (FBGA-484) package at the -2 speed grade and industrial (I) temperature rating. It is built on a 45 nm CMOS process and operates from a 1.14 V to 1.26 V core supply, delivering up to 667 MHz internal performance. A Field-Programmable Gate Array (FPGA) is a reconfigurable digital integrated circuit containing an array of programmable logic blocks, programmable interconnect, and dedicated silicon resources (Block RAM, DSP slices, PLLs, transceivers on some variants) that can be hardware-tailored after PCB assembly. FPGAs sit between fixed-function ASICs and software-programmable processors in the compute taxonomy: integrated circuit -> digital IC -> programmable logic -> FPGA -> Spartan-6 family -> LX (logic-optimized) sub-family. They are used when time-to-market, parallel processing, and hardware reconfigurability outweigh the unit-cost advantage of mass-produced ASICs. Key features of the XC6SLX75-2FGG484I include 11,650 logic slices (each containing four 6-input LUTs and eight flip-flops), 3,170 Kbits of dedicated Block RAM (180 18-Kbit blocks), 132 DSP48A1 slices for fixed- and floating-point arithmetic, six clock management tiles (CMTs) with PLL + DLL capability, integrated PCIe endpoint block (only on LXT, NOT on LX), and on-chip 100 MHz clock support with up to 667 MHz DCM/PLL output. The -2 speed grade balances performance and power versus the -3 (highest performance) and -1L (lowest power) grades. Industrial temperature grade (-40 °C to +100 °C ambient, with junction allowed up to +125 °C) supports harsh-environment deployment. Spartan-6 LX uses a 45 nm 9-metal-layer CMOS process and a power-optimized core that supports 1.2 V core operation. Hard IP blocks (Block RAM, DSP slices, multi-boot controller, JTAG/ICAP/SPI configuration ports) live alongside the programmable fabric, enabling deterministic single-chip solutions for bridging, motor control, video processing, and embedded compute. Typical applications include industrial automation controllers, automotive infotainment bridging, video processing pipelines, software-defined radio, portable medical imaging, LED video walls, and PCIe endpoint expansion bridges. The 280 user I/Os make the 484-BGA package especially well-suited for high-pin-count industrial designs where several external buses must be addressed simultaneously. When designing with this FPGA, allocate at least 0.5 A per 100 K logic cells for VCCINT, and follow AMD UG393 (Spartan-6 PCB Design Guide) for decoupling, pinout, and signal-integrity rules. Industrial-grade parts cost roughly 20-30 % more than commercial-grade XC6SLX75-2FGG484C and should be chosen only when the operating environment exceeds 0 °C to +85 °C. This page synthesizes distributor pricing, drop-in replacement candidates, and design notes that are not consolidated in the AMD Spartan-6 datasheet alone.
XC6SLX75-2FGG676I - 74,637-Cell Spartan-6 FPGA | AMD
The AMD XC6SLX75-2FGG676I is a Spartan-6 LX field-programmable gate array with 74,637 logic cells, 5,831 configurable logic blocks, 408 I/O, and a maximum internal frequency of 667 MHz. The device is supplied in a lead-free 676-ball FBGA package measuring 27 mm by 27 mm with a 1 mm ball pitch, and its -2 speed grade supports a nominal 1 V supply. A field-programmable gate array is a programmable semiconductor in the FPGA category of digital logic devices. An FPGA combines configurable logic blocks, programmable interconnect, memory resources, and input/output blocks into an integrated circuit whose circuit behavior can be modified after manufacture. Within the broader semiconductor hierarchy, the Spartan-6 LX device provides a programmable alternative to application-specific integrated circuits when interfaces, parallel processing, or logic capacity must change between product variants. Principal device characteristics include 74,637 logic cells, 5,831 configurable logic blocks, 408 I/O, 667 MHz internal frequency, and operation from approximately -40°C to +100°C for the industrial-temperature ordering indicated by the I suffix. The 676-ball FBGA package supports dense board-level integration, while the lead-free construction is explicitly identified in the available product records. The -2 designation identifies the device's performance grade within the Spartan-6 LX family, which is manufactured on 45 nm CMOS technology. Its 676-ball package provides a high pin count for high-performance design implementations, including parallel data interfaces, embedded control, industrial automation, networking equipment, and general-purpose signal processing. System timing must still be evaluated against the specific clock, I/O, and resource requirements of each implemented design. Typical applications include industrial control systems, embedded video processing, communication infrastructure, test equipment, and high-density programmable logic. The combination of 408 I/O and 74,637 logic cells permits multiple interfaces to be consolidated in one device, reducing the need for separate programmable or discrete interface components when pin and performance requirements are satisfied. A primary design consideration is BGA assembly. The 1 mm pitch, 676-ball package requires a suitable land pattern, multilayer PCB construction, appropriate thermal management, and assembly-process controls. Designers should also confirm timing closure, power budget, configuration method, bank voltage requirements, and I/O standards against the manufacturer datasheet before releasing a production design.

XC6SLX75-3CSG484C - Spartan-6 LX FPGA, 74K Logic Cells, 484-BGA | AMD
The AMD (formerly Xilinx) XC6SLX75-3CSG484C is a Spartan-6 LX family Field-Programmable Gate Array (FPGA) built on a 45 nm low-power copper CMOS process, integrating 74,637 logic cells and 3,170,304 system gates into a 484-ball Chip-Scale BGA (CSBGA) package measuring 23 x 23 mm with 1.0 mm ball pitch. It targets high-volume cost-sensitive applications requiring high logic density with low static and dynamic power. What is a Spartan-6 FPGA? The Spartan-6 family is the sixth generation of Xilinx's low-cost, high-volume FPGA line, sitting within the broader taxonomy of programmable logic devices (PLD) -> FPGA -> SRAM-based FPGA -> low-power FPGA. Built on a mature 45 nm process, Spartan-6 devices combine programmable logic fabric, Block RAM, DSP slices, and hard IP cores (clock management, PCIe, memory controllers) into a single die, offering ASIC-like integration at FPGA-like flexibility. Key features of the XC6SLX75 include 5831 Configurable Logic Blocks (CLBs), up to 309 Kbits of Block RAM, a maximum internal operating frequency of 667 MHz, and 328 user I/O pins. The device is offered in the -3 speed grade (the highest performance tier of the LX family), commercial temperature range (0 to 85 C), and supports supply voltages from 1.2 V core to 3.3 V I/O. Integrated hard IP includes DSP48A1 slices for fixed- and floating-point arithmetic, SelectIO with support for multiple I/O voltages, and a memory controller block for DDR, DDR2, DDR3, and LPDDR. The LX sub-family is positioned below the LXT (which adds transceivers) and above the Spartan-6 lower-density LX devices. Architecture highlights include 6-input LUTs, dual-port Block RAM with byte-wide parity, and dedicated 18 x 18 multipliers. The 45 nm process yields approximately 50% lower static power than the prior Spartan-3A generation while supporting higher clock rates through dedicated carry chains and pipelined DSP blocks. Typical applications for the XC6SLX75-3CSG484C include industrial motor control and machine vision, video processing pipelines (display controllers, surveillance DVRs), wireline communication bridges, automotive driver assistance, and consumer display interfaces. The 484-BGA footprint and high I/O count suit designs that need many LVCMOS or LVDS pairs. When designing with this device, provide multiple decoupling caps around the BGA and follow AMD's PCB layout guidelines for chip-scale BGAs (escape routing for the 1.0 mm pitch grid). Use the ISE Design Suite (iMPACT + ISE Project Navigator) or Vivado (legacy support) for bitstream generation and JTAG programming.
