These resources make the device useful for designs combining a processor or microcontroller with dedicated high-speed or parallel logic. Designers should use the official Spartan-6 package pinout and power-guidance documents rather than inferring BGA connectivity from a generic package drawing. PCB layout must provide the specified core and I/O supplies, decoupling, clocking, configuration storage, and exposed-pad thermal treatment. Because the supplied data does not contain the complete 256-ball pinout or recommended operating ranges, those details remain data-needed rather than being inferred. This product page consolidates the verified 24,051-cell, 1.2 V, 45 nm, 256-pin device attributes, current distributor pricing, same-family drop-in candidates, and practical replacement guidance. It provides engineering context that is not available from a distributor inventory listing alone, while clearly separating verified facts from documentation that still requires confirmation.

XC6SLX25-N3FG484C

XC6SLX25-N3FG484C - 24,051-Cell Spartan-6 LX FPGA | AMD

AMD XC6SLX25-N3FG484C is a Spartan-6 LX field-programmable gate array with 24,051 logic cells, 1,879 logic blocks, 958,464 RAM bits, and 266 programmable I/O pins in a 484-pin FBGA package. The device uses 45 nm fabrication technology and operates from a 1.14 V to 1.26 V internal core supply, while its commercial temperature range extends from 0°C to 85°C junction temperature. These characteristics place it in the FPGA & CPLD category as a configurable semiconductor for parallel processing, control, interface, and embedded-logic systems. A field-programmable gate array is a programmable-logic device whose configurable logic blocks, block RAM, programmable I/O, and dedicated resources can be configured after manufacture. An FPGA sits above simple fixed-function logic in the product hierarchy: fixed-function controllers and discrete logic provide predetermined behavior, while an FPGA supports reconfigurable hardware, parallel data paths, adaptable interfaces, and product updates without changing the PCB. The Spartan-6 LX architecture therefore serves as a programmable-logic platform rather than a conventional microcontroller. The XC6SLX25 combines 24,051 programmable logic cells with 266 I/O and 958,464 RAM bits, creating a useful balance between computation and interface capacity. Its 45 nm process technology supports a compact, power-efficient implementation for embedded control, industrial automation, communications, instrumentation, and consumer equipment. The 484-pin FBGA package also provides enough physical connections for wide external data buses, multiple memory interfaces, clocks, and control signals. The -N3FG484C ordering code identifies a Spartan-6 LX resource configuration in the 484-pin FBGA package, while the final C suffix identifies the commercial temperature option. The commercial-grade junction-temperature specification of 0°C to 85°C suits designs operating in controlled indoor, laboratory, telecom, and industrial enclosure environments. Designers must still verify board-level airflow, local heat spreading, and the maximum ambient temperature permitted by the complete system. Typical applications include industrial control and data acquisition, embedded communications gateways, test and measurement instruments, video and image processing, motor-control supervisory logic, and general-purpose accelerator boards. The FPGA can implement parallel algorithms, state machines, protocol conversion, sensor aggregation, and memory-control functions in one device. Designs that require deterministic timing can use dedicated clocking and I/O resources while assigning repetitive operations to configurable logic blocks. The main design consideration is package complexity. A 484-pin FBGA demands careful escape routing, via planning, power-plane integrity, and assembly capability. Follow the AMD Spartan-6 package pinout files for ball assignments and PCB escape geometry. Place decoupling capacitance near the relevant supply balls, keep sensitive clock and configuration paths short, and verify the selected memory interface, I/O standards, clocking topology, and thermal conditions with the manufacturer datasheet and design-tool guidance.

XC6SLX4-2TQG144C - Spartan-6 LX FPGA 4K Logic Cells | AMD Xilinx

The AMD Xilinx XC6SLX4-2TQG144C is a Spartan-6 LX family Field-Programmable Gate Array (FPGA) offering 3,840 logic cells, 4,860 Kbits of block RAM, and 102 user I/Os in a 144-pin LQFP (TQG144) package. The -2 speed grade targets commercial temperature operation (0 °C to +85 °C), and the 'C' suffix indicates the commercial temperature tier suitable for most industrial and consumer environments. An FPGA (Field-Programmable Gate Array) is a class of programmable logic device containing an array of configurable logic blocks (CLBs), programmable interconnect, and dedicated silicon blocks such as Block RAM, DSP slices, and clock management tiles. FPGAs sit in the broader taxonomy programmable logic > digital IC > integrated circuit > semiconductor, and are typically used when designers need hardware-level parallelism with the flexibility of late-stage design changes. Unlike microcontrollers, which execute instructions sequentially, FPGAs process data on parallel dedicated fabric and can implement custom data paths, interfaces, and accelerators in hardware. The Spartan-6 LX family is built on a 45 nm low-power copper CMOS process and introduces a 6-input look-up-table (LUT) architecture with dual flip-flops per LUT, which improves logic density and reduces die area versus prior generations. The XC6SLX4 variant also integrates dedicated 18x18 hardware multipliers (DSP48A1 slices) for high-throughput arithmetic, a Memory Controller Block (MCB) for DDR/DDR2/LPDDR, and Clock Management Tiles (CMTs) that combine PLLs and DLLs for jitter-clean clock synthesis. Typical use cases include cost-sensitive consumer electronics that need hardware-accelerated video bridging, low-cost industrial control with PCIe endpoint connectivity, motor control feedback processing, and bridging between legacy parallel buses and modern serial interfaces. Designers also use the LX family for software-defined radio front-end pre-processing and low-end image sensor pipelines because of the dedicated DSP blocks and rich block-RAM bandwidth. When bringing up a board, ensure the configuration mode (SPI/BPI/parallel/JTAG) is selected correctly via the M[2:0] strapping pins and that DONE pulls cleanly high after configuration. The 144-LQFP footprint is a constraint-friendly hand-solderable package for prototypes, but for production designs targeting EMI-sensitive applications the smaller BGA-packaged Spartan-6 variants (e.g. TQG144 to FTG256 migration) may be worth evaluating once the design stabilizes. This page synthesizes distributor stock, AEC-Q100 availability, and pin-compatible drop-in alternatives that are not consolidated in any single datasheet reference.

The AMD XC6SLX4-2TQG144I is a Spartan-6 LX field-programmable gate array with 3,840 logic cells, 221,184 bits of RAM, and 102 available I/O pins in a 144-pin TQFP package. The -2 speed grade operates from a 1.14 V to 1.26 V supply, and verified distributor data identifies a maximum clock frequency of 375 MHz. It also provides digital clock management and PLL resources for clock generation, conditioning, and phase alignment. The XC6SLX4 combines programmable logic, block RAM, programmable I/O, and dedicated clocking resources in one reconfigurable device. An FPGA, or field-programmable gate array, is a semiconductor whose digital logic, interconnect, and I/O behavior can be configured after manufacture. FPGAs sit above fixed-function logic devices in the hardware hierarchy and are commonly used where protocols, interfaces, control logic, or product requirements must change without redesigning an ASIC. The Spartan-6 family targets cost-sensitive embedded systems, industrial controls, communications interfaces, signal processing, and general programmable-logic applications. The XC6SLX4 includes 3,840 logic cells, 221,184 bits of RAM, 102 user I/O, DCM, and PLL resources according to the supplied distributor and technical data. Its 144-pin TQFP package uses a 0.5 mm pitch and a 20 mm by 20 mm body. The industrial-temperature suffix and lead-free status are supported by the retrieved part data, but exact temperature limits, electrical timing limits, and detailed compliance certificates were not included in the source set and require confirmation from the manufacturer datasheet. The -2 designation identifies the performance grade, while TQG144I identifies the package and temperature-market ordering options. Designers must configure the FPGA using an AMD-supported device definition and ensure that every external interface uses the correct voltage, slew, drive-strength, and timing constraints. Clocking should be planned carefully because incorrect clock constraints or phase relationships can make an otherwise valid design fail post-route timing. Typical uses include industrial data acquisition, embedded communications bridges, motor and motion control, sensor aggregation, protocol conversion, and control systems with parallel or serial interfaces. The 102 available I/O pins are useful for parallel buses, while the clocking and RAM resources can support buffering, state machines, packet handling, and sampled-data paths. The device is best suited to designs that need moderate logic density and flexible field updates. A key design consideration is that FPGA interchangeability depends on the bitstream, pin constraints, supported I/O standards, timing closure, and package footprint. Before purchasing a replacement, verify the exact MPN suffix, package drawing, pinout, configuration voltage, memory initialization, and supported design tools.

The device combines configurable logic, block RAM, dedicated digital clocking resources, programmable I/O, and on-chip support features within one integrated package. Its -3 speed grade is intended to provide higher timing performance than lower-numbered Spartan-6 speed grades. Because an FPGA is a programmable digital device, final performance also depends on placement, routing, clocking, I/O standards, memory interfaces, and the selected tool version; the 862 MHz figure should therefore not be interpreted as a guaranteed operating frequency for every design. Typical uses include industrial control, networking equipment, embedded instrumentation, video interfaces, sensor processing, and communications bridges. Its 102 I/Os make it suitable for designs needing substantial external connectivity, while 221,184 bits of embedded RAM can support buffering, packet handling, data acquisition, and general-purpose state storage. The 20 x 20 mm LQFP footprint is also practical for boards that cannot accommodate very dense BGA packages. A key design consideration is the device's relatively low logic-cell count compared with larger Spartan-6 devices. Designs requiring multiple high-speed interfaces, large frame buffers, or substantial parallel processing may need a larger FPGA. Engineers should also verify speed-grade timing against the slowest clock domain and use the AMD Spartan-6 package pinout files when assigning all 144 package pins. This product page consolidates verified distributor specifications, a complete same-package alternative set, practical application guidance, and design cautions that are not presented together in a single manufacturer datasheet.

For these applications, the L1 device provides a practical balance between logic density, memory, DSP capability, and power efficiency. Configuration should be planned with the manufacturer's configuration guidance so the FPGA receives a valid bitstream at power-up. PCB design should preserve clean power distribution to the 1.0 V core and associated supply rails, provide decoupling close to the device, and route sensitive inputs away from high-speed outputs. Thermal performance depends on the board, copper area, airflow, and total switching activity, so an enclosure-level estimate is more meaningful than package size alone. Use the AMD package files and Spartan-6 documentation to validate every connection. This product page combines the exact XC6SLX4-L1CSG225I identifiers with practical selection guidance, verified resource counts, package considerations, and engineering-focused design notes. It helps teams distinguish the low-power industrial device from other Spartan-6 LX speed and package options before committing a board to the CSG225 footprint.

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.

XC6SLX45-2FGG484C - Spartan-6 LX FPGA, 43,661 Logic Cells | AMD

The AMD (formerly Xilinx) XC6SLX45-2FGG484C is a Spartan-6 LX field-programmable gate array (FPGA) integrating 43,661 logic cells, 2,138,112 system gate equivalents, and 316 user I/O pins in a 484-ball fine-pitch BGA package (FGG484). It is offered in the -2 commercial speed grade with a 1.14 V to 1.26 V core supply. A Field Programmable Gate Array (FPGA) is a reconfigurable semiconductor device whose logic and routing are defined by a user-programmed configuration bitstream rather than at fabrication. FPGAs occupy the wider hierarchy of programmable logic devices (PLD) -> reconfigurable logic -> parallel processing accelerators -> digital integrated circuits (IC). The Spartan-6 family specifically targets cost-sensitive, high-volume embedded designs where power efficiency and integrated peripherals matter more than the absolute performance of a Virtex-class device. Key features of the XC6SLX45 include 2,011 Kbit of block RAM, 58 DSP48A1 slices running up to 390 MHz, four clock management tiles (CMTs) each containing two DCMs and one PLL, and SelectIO technology supporting I/O voltages from 1.2 V to 3.3 V on a per-bank basis. The device also exposes an integrated hard Endpoint block for PCI Express Gen1 in the LXT variant, plus a 10/100/1000 Ethernet MAC. The FGG484 package, measuring 23 x 23 mm with 1.0 mm pitch, is pin-compatible across all Spartan-6 LX/LXT devices with this ball-out. 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.

XC6SLX45-2FGG484I - Spartan-6 LX FPGA, 43,661 Logic Cells | AMD

The AMD (formerly Xilinx) XC6SLX45-2FGG484I is a Spartan-6 LX Field Programmable Gate Array (FPGA) delivering 43,661 logic cells, 2,138,112 bits of block RAM, and 316 user I/O pins in a 484-ball fine-pitch BGA package. Built on a 45 nm low-power copper CMOS process, the -2 speed grade targets an industrial operating temperature range (-40C to +100C for the I suffix), and supports DDR3, LVDS, and 3.3V I/O standards. An FPGA (Field-Programmable Gate Array) is a programmable logic device containing an array of configurable logic blocks (CLBs), programmable interconnect, and dedicated silicon blocks such as block RAM, DSP slices, and clock management tiles. Within the broader semiconductor taxonomy, FPGAs sit between general-purpose microcontrollers and ASICs: they are slower and more power-hungry than purpose-built ASICs but offer complete hardware re-programmability, making them ideal for prototyping, low-volume production, and designs requiring hardware acceleration. The Spartan-6 LX family is positioned as a cost-optimized, high-volume family aimed at bridging, motor control, video processing, and embedded DSP applications. Key features of the XC6SLX45 include 6,822 logic slices (each containing four 6-input LUTs and eight flip-flops), 58 DSP48A1 slices for fixed- and floating-point math, 12 clock management tiles (CMTs) with PLL and DCM blocks, and integrated hard IP for PCI Express and GTP serial transceivers on the LXT sub-family. The device supports up to 800 Mbps LVDS, 1,066 Mbps DDR3 memory interfaces, and offers 16 dedicated multiplier lines and SelectIO technology for flexible I/O standard support. The architecture uses a hierarchical routing fabric with 3-fine-tolerant ASIC-class clock networks, making timing closure predictable. The 45 nm process yields roughly half the static power of prior Spartan generations. Built-in security features include AES-256 bitstream encryption and Device DNA for IP protection, supporting secure field upgrades in deployed systems. Typical applications include industrial machine vision, motor and motion control, automotive infotainment bridging, video surveillance and broadcast equipment, low-cost software-defined radio, and high-volume consumer products needing DSP pipelines. The 316 user I/Os and abundant block RAM make it well-suited for multi-channel data acquisition systems. The -2 speed grade balances performance and power for cost-sensitive industrial designs that do not require the fastest -3 grade. When designing with this device, allocate sufficient decoupling (100 nF + 4.7 uF per VCCIO/VCCAUX rail), use 1.0 mm-pitch BGA fanout with microvia stacks, and route the 484-ball FBGA substrate with a symmetrical thermal copper pour to keep junction temperature within industrial limits. The design should use the Xilinx ISE Design Suite or Vivado for synthesis, place-and-route, and bitstream generation.
