XC6SLX45T-2FG484I - 43,661-Cell Spartan-6 LXT FPGA | AMD
MPN: XC6SLX45T-2FG484I ✗ End of LifeXC6SLX45T-2FG484I Overview
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.

Typical Applications
XC6SLX45T-2FG484I is suitable for 6 applications: Industrial Control Gateway, Network Communication Equipment, Video and Image Processing, Test and Measurement Instrumentation, Embedded Consumer Electronics, Programmable Logic Control Platform.
Industrial Control Gateway
The XC6SLX45T-2FG484I fits industrial gateways that translate between legacy parallel equipment and modern serial networks. Its 43,661 logic cells and 296 I/O can host protocol state machines, buffering, timing, and supervisory logic in one programmable device, while the listed 667 MHz figure provides timing margin for common control interfaces. The industrial I suffix supports evaluation for industrial environments, although exact temperature limits must be confirmed from the AMD datasheet. On the PCB, the 484-BBGA package supports dense I/O assignment, while the implementation team must provide controlled high-density assembly, continuous power planes, thermal copper, and validated configuration storage.
Recommended
Network Communication Equipment
The Spartan-6 XC6SLX45T-2FG484I is suitable for protocol conversion, packet processing, and multi-interface communications equipment. Its 6,822 adaptive logic modules and 3,411 CLBs provide substantial parallel processing capacity without requiring a separate ASIC, while 296 I/O can accommodate byte-wide buses and multiple PHY or serial interfaces. The verified 667 MHz figure is useful for timing-constrained pipeline logic. Designers should use clock-capable pins for high-speed paths, constrain all clocks, and reserve configuration resources according to the AMD design guidance. The 1.2 V core supply also requires a low-noise regulator and careful decoupling close to the device.
Recommended
Video and Image Processing
The XC6SLX45T-2FG484I can implement pixel pipelines, color conversion, frame timing, and interface adaptation in embedded imaging systems. Its 43,661 logic cells and 296 I/O permit parallel video-data routing and control logic to coexist in the same FPGA, while the listed 667 MHz figure supports clocked processing stages. The high I/O count is particularly valuable when connecting sensors or displays that expose parallel data buses. Practical designs must balance external memory bandwidth, constrain video timing precisely, and account for power consumed by large parallel switching fabrics. A 484-BBGA footprint with 1.0 mm pitch demands assembly validation and reliable thermal spreading under sustained image-processing workloads.
Recommended
Test and Measurement Instrumentation
The XC6SLX45T-2FG484I is applicable to programmable test, measurement, and signal-conditioning systems where acquisition control, timing generation, and analysis must be consolidated. Its 43,661 logic cells can support parallel data capture, trigger logic, calibration tables, and communication interfaces, while the 296 I/O count provides broad connectivity to sensors and front-end circuits. The -2 grade and 667 MHz listed frequency are useful for deterministic instrumentation control, subject to the final timing budget. Engineers should reserve dedicated clock-management resources, implement JTAG access for diagnostics, and separate analog-sensitive circuitry from high-speed digital switching. Configuration should also include a safe recovery path for field-updated instruments.
Recommended
Embedded Consumer Electronics
The XC6SLX45T-2FG484I fits cost-sensitive embedded products that need flexible logic, multiple interfaces, and field-configurable behavior. Instead of combining several fixed-function ICs, a design can use the FPGA's 43,661 logic cells for control, display, accessory, and protocol functions. Its 296 I/O is useful for legacy connectors, while its 45 nm CMOS construction reflects the Spartan-6 generation's focus on high-volume integration. The main tradeoff is package complexity relative to a leaded or smaller-BGA device. A successful implementation requires a stable configuration source, factory programming support, production test access, and assembly capability for the 484-BBGA footprint with 1.0 mm pitch.
Recommended
Programmable Logic Control Platform
The XC6SLX45T-2FG484I supports a consolidated control platform for factories, appliances, and specialized equipment that benefit from adaptable hardware. Designers can implement sequencers, safety interlocks, counters, motor-control support logic, and communications in one device, using its 296 I/O to connect sensors and actuators. The listed 667 MHz figure allows clocked control logic to operate alongside slower supervisory tasks. Because the part is a programmable FPGA rather than a real-time microcontroller, deterministic execution must be established through a documented clocking and arbitration architecture. Thermal and signal-integrity reviews are especially important because wide parallel routing can increase switching activity on the 1.2 V core rail.

Design Notes
Create the board footprint from AMD's official Spartan-6 package files rather than converting a generic 484-BBGA symbol. The verified package is 23 mm by 23 mm with 1.0 mm ball pitch. Confirm pad dimensions, solder-mask and paste-mask apertures, via-in-pad requirements, and assembly tolerances against the current AMD package documentation before releasing the PCB.
Provide a low-noise 1.2 V core rail with dense local decoupling and verify sequencing against the device's power requirements in the official family documentation. Keep the regulator, core capacitors, and power-plane connections close to the FPGA. Because the supplied snippets do not state I/O supply limits, transient requirements, or recommended capacitor values, those values must be taken from the manufacturer datasheet rather than inferred.
Use a continuous thermal-via field and copper spreader beneath the 484-BBGA to move heat from the device into the board. Perform thermal analysis using actual logic utilization, clock activity, I/O loading, ambient temperature, and the verified junction-temperature limit from AMD documentation. The supplied data does not provide power coefficients or package thermal resistance, so a defensible junction-temperature estimate cannot be produced from these excerpts alone.
Compliance Information
The verified results do not provide explicit compliance statements for the target MPN. The I suffix identifies an industrial-temperature ordering option, not AEC-Q100 qualification.
