XC6SLX75T-2FG484I - 74K Spartan-6 LXT FPGA | AMD
MPN: XC6SLX75T-2FG484I ✗ End of LifeXC6SLX75T-2FG484I Overview
A field-programmable gate array, or FPGA, is a semiconductor whose digital logic, memory, and I/O behavior are configured after manufacture. An FPGA belongs to the programmable-logic hierarchy and combines parallel programmable logic blocks with configurable input/output resources. This integration allows one physical device to implement control logic, signal processing, interface bridging, and embedded system functions without relying on a large collection of fixed-function logic ICs.
The Spartan-6 LX device family combines substantial programmable logic capacity with a high number of user I/Os. In the XC6SLX75T-2FG484I, 268 I/Os support communication with external processors, memory, converters, sensors, and industrial peripherals. The -2 performance grade and 667 MHz stated operating speed place the device in the Spartan-6 LX performance range, while the industrial-temperature suffix supports equipment designed for extended commercial and industrial operating environments.
The 484-ball FBGA package uses a 1 mm pitch and provides a compact, high-pin-count surface-mount footprint. Its 23 x 23 mm body makes it appropriate for dense control boards, but the fine ball pitch requires careful PCB layout, manufacturing control, inspection, and connector or test-point planning. The LXT designation also identifies this as a Spartan-6 member intended for designs requiring more logic resources and I/O capacity than smaller LX variants.
Typical uses include industrial automation, data acquisition, motion control, communications gateways, embedded instrumentation, and general-purpose digital signal processing. Its combination of 74,637 logic elements, 5,831 configurable logic blocks, and 268 I/Os is particularly useful when several parallel control paths, high-speed interfaces, and protocol conversion functions must share one programmable device.
PCB design should follow the AMD Spartan-6 package pinout files for every ball assignment and keep sensitive interfaces away from noisy power and switching paths. Decoupling, clock routing, configuration handling, bank voltage planning, and thermal performance require careful implementation before the FPGA is released for production.

Typical Applications
XC6SLX75T-2FG484I is suitable for 6 applications: Industrial Automation and PLC Control, Data Acquisition and Instrumentation, Communications Gateway and Protocol Conversion, Embedded Signal Processing, Motor Control and Power-System Management, Aerospace and Defense Test Equipment.
Industrial Automation and PLC Control
The XC6SLX75T-2FG484I fits industrial controllers that coordinate motion, interlocks, actuators, sensors, and communications in parallel. Its 74,637 logic elements and 5,831 configurable logic blocks provide substantial capacity for state machines, timing logic, protocol conversion, and diagnostic logic, while 268 I/Os provide substantial connectivity to field-level circuits. The industrial-temperature order code is suitable for product platforms designed around extended industrial environments. Designers should assign I/O standards by bank, protect externally accessible signals, and isolate noisy relays or motor-drive stages from precision logic where practical.
Recommended
Data Acquisition and Instrumentation
The XC6SLX75T-2FG484I is appropriate for parallel data-acquisition systems that must combine sensor conditioning, digital filtering, calibration tables, and a communications interface. Its 74,637 logic elements and 5,831 configurable logic blocks can support multiple processing pipelines concurrently, while 268 I/Os allow the device to interface with ADC data buses, status lines, clocks, and control signals. The stated 667 MHz operating speed supports timing-intensive digital functions. Board design should use controlled clock distribution, provide local decoupling for every supply group, and keep analog and digital grounding strategies consistent with the selected analog front end.
Recommended
Communications Gateway and Protocol Conversion
The XC6SLX75T-2FG484I can serve in gateways that translate between serial, parallel, memory-mapped, and packet-oriented interfaces. Its 5,831 configurable logic blocks and 74,637 logic elements are well suited to concurrent buffering, framing, checksum, routing, and flow-control functions. With 268 I/Os, the device can support multiple external buses and control channels without relying on a large fixed-function chipset. Engineers should define clock-domain boundaries, constrain high-speed interfaces, and budget memory or external storage resources early because protocol conversion can consume logic and bandwidth faster than simple combinational control.
Recommended
Embedded Signal Processing
The XC6SLX75T-2FG484I supports parallel filtering, correlation, modulation, waveform generation, and fixed-point signal-processing pipelines. Its 74,637 logic elements provide more implementation headroom than a small control FPGA, while the stated 667 MHz operating speed supports pipelined processing at useful clock rates. The 268 I/Os can connect the processor to parallel ADC or DAC data buses, memory, synchronization signals, and external peripherals. For reliable results, use synchronous design practices, pipeline arithmetic stages, apply appropriate clock constraints, and verify timing against all supported clock and configuration conditions.
Recommended
Motor Control and Power-System Management
The XC6SLX75T-2FG484I can coordinate control sequencing, fault detection, pulse generation, and supervisory logic in motor-drive or power-conversion systems. Its extensive logic capacity allows current control, position tracking, protection state machines, and communications logic to coexist, while 268 I/Os simplify connection to gate drivers, position sensors, measurement systems, and safety-related discrete logic. The FPGA should remain separated from high-dv/dt power stages through appropriate isolation, filtering, and grounding. Production designs must also review the exact device temperature limits, operating voltages, transient behavior, and functional-safety requirements.
Recommended
Aerospace and Defense Test Equipment
The XC6SLX75T-2FG484I can implement compact test and simulation systems when the surrounding equipment requires deterministic parallel logic, extensive interface connectivity, and programmable functionality. Potential uses include automated test equipment, avionics interface simulators, fault-injection systems, and programmable signal-generation platforms. The device's 74,637 logic elements and 268 I/Os allow one FPGA to coordinate acquisition, sequencing, and external communication. Because program-specific aerospace and defense requirements may exceed ordinary industrial specifications, engineers should confirm the exact ordering code, radiation, temperature, traceability, and qualification requirements before using the part in a safety-critical or export-controlled system.

Design Notes
Treat the 484-ball FBGA as a fine-pitch assembly requiring a controlled PCB footprint and manufacturing process. Assign signals directly from the AMD package-device pinout file, preserve the exposed thermal and power-distribution structures required by the package documentation, and verify solder-mask, paste, and inspection capabilities at 1 mm pitch. Avoid constructing the footprint from visual ball spacing alone because package-specific mechanical tolerances and markings affect assembly.
Plan the complete power tree before routing high-speed interfaces. The device's 484-ball package provides many connections, but each supply domain still requires adequate decoupling and distribution. Place bulk and high-frequency decoupling capacitors close to their associated supply and ground balls, follow the manufacturer guidance for each rail, and confirm voltage-bank compatibility before assigning an I/O standard. Configuration voltage, auxiliary voltage, and normal operating supplies must remain within their specified limits.
Reserve a clear configuration and startup strategy that matches the complete device order code. Use dedicated clock-capable pins for system clocks where required, avoid routing sensitive clock or differential pairs through noisy power-stage areas, and apply source-synchronous or other appropriate PCB constraints for high-speed interfaces. Because the device has 268 I/Os, assign board functions and voltage standards during schematic capture rather than after PCB routing begins.
Do not interchange the target XC6SLX75T-2FG484I with similarly named 484-ball Spartan-6 order codes solely because their logic capacity matches. Verify the complete MPN, temperature suffix, performance grade, package code, and applicable AMD pinout file. A suffix change can alter ordering qualification or documentation without changing the broad 74,637-logic-element device family, making procurement and design traceability essential.
