An FPGA is a reprogrammable semiconductor device that implements digital logic through configurable logic blocks and programmable interconnects. Within the programmable-logic hierarchy, the SX-A sits under antifuse FPGAs -> FPGAs -> programmable logic ICs -> embedded ICs. Unlike SRAM-based FPGAs, the SX-A family uses antifuse programming technology, which retains its configuration permanently and is inherently more resistant to configuration readback and single-event upset, making the family attractive for high-reliability and long-lifecycle systems.
Key features of the A54SX32A include a 0.25 um CMOS process technology, low power consumption typical of antifuse architectures (no configuration SRAM to power), and single-chip integration that replaces multiple glue-logic devices. The device is fabricated on a proven 0.25 um CMOS process, delivering deterministic timing and the security benefits of antifuse programming, which cannot be read back after programming.
Technically, the SX-A architecture provides combinational and sequential logic capacity with dedicated flip-flops enabling synchronous design methodologies. Design entry and programming are performed using Microchip (Microsemi) Libero SoC design tools, and one-time programmable antifuse programming delivers permanent configuration without an external boot device.
Typical applications include industrial control, communications equipment, aerospace and defense subsystems (via industrial/military temp variants), medical instrumentation, and legacy system sustainment where a mature, proven FPGA is required.
A key design consideration is that antifuse FPGAs are one-time programmable: design changes require a new device, so verify the design fully in simulation before programming. Pricing on this page is referenced as of 2026-09-03.

יישומים טיפוסיים
A54SX32A-TQG100A מתאים עבור 6 יישוםs: Industrial Control and Automation, Communications Equipment, Aerospace and Defense Subsystems, Medical Instrumentation, Legacy System Sustainment and Obsolescence Management, Test and Measurement Equipment.
Industrial Control and Automation
The A54SX32A-TQG100A fits industrial control by consolidating PLC glue logic, bus interfacing, and sequencing functions into one antifuse FPGA with 48,000 gates and 81 user I/O on a 0.25 um CMOS process. Its instant-on antifuse configuration means control logic is active the moment power is applied, with no boot delay or external configuration device that could fail in the field. In a typical installation the device sits between a microcontroller and motor drives or field sensors, implementing state machines and safety interlocks with deterministic, security-resistant configuration that cannot be read back or altered in service.
מומלץ
Communications Equipment
In telecom and datacom line cards, the A54SX32A-TQG100A implements framing, address decoding, and backplane interface logic where 81 user-programmable I/O and up to 108,000 system gates provide ample routing resources. The antifuse architecture delivers deterministic timing suited to synchronous backplane protocols and avoids configuration-upset risk during long unattended operation, a known weakness of SRAM FPGAs. Designers typically place it between physical-layer devices and a back-end processor, using the Libero flow to close timing; the permanent configuration also reduces bill-of-materials cost by eliminating the serial flash that SRAM FPGAs require.
מומלץ
Aerospace and Defense Subsystems
Although the commercial-grade A54SX32A-TQG100A is aimed at benign environments, the SX-A antifuse family is widely used in aerospace and defense sustainment programs because its configuration cannot be read back and is inherently resistant to configuration single-event upset. Designers prototype on the commercial grade and migrate to industrial or military SX-A ordering codes for flight builds, retaining the same 100-TQFP footprint. Typical roles include telemetry encoding, arbitration logic, and interface bridging between rad-hard processors and peripheral circuits, with the 2,012 dedicated flip-flops supporting registered, pipeline-heavy designs.
מומלץ
Medical Instrumentation
Medical diagnostic equipment such as patient monitors and lab analyzers benefits from the A54SX32A-TQG100A's combination of 48,000 gates, 81 flexible I/O, and permanent antifuse configuration. Instrument front ends use the FPGA to sequence ADC sampling, drive actuator logic, and buffer data between analog front ends and host processors; the deterministic, instantly-loaded configuration simplifies power-on self-test routines required by regulatory validation. Because medical products have long service lives, the mature, single-sourced SX-A family with documented 0.25 um CMOS process characteristics supports sustained production and change-controlled design baselines.
מומלץ
Legacy System Sustainment and Obsolescence Management
A major use of the A54SX32A-TQG100A is replacing discontinued PLDs and glue-logic in long-lifecycle systems. With 48,000 gates, up to 108,000 system gates, and 81 I/O, one antifuse device can absorb dozens of legacy PAL/GAL/CPLD functions, and its one-time programming permanently fixes the configuration in silicon - no configuration memory to obsolesce. Engineers port legacy schematics into Microchip Libero, close timing, and program new SX-A devices to repair or extend the life of industrial, transportation, and defense platforms where redesigning around a modern FPGA would require costly full-board requalification.
מומלץ
Test and Measurement Equipment
Bench instruments, automated test fixtures, and production test heads use the A54SX32A-TQG100A for timing generation, pattern multiplexing, and interface adaptation. The 2,012 dedicated flip-flops support deep pipelining for pattern engines, and the 81 user I/O handle parallel fixture interfaces; the antifuse configuration loads instantly at power-up so test fixtures are ready with zero boot latency. Deterministic internal timing on the 0.25 um CMOS process simplifies correlation between test stations. Its single-chip integration also reduces fixture part count and improves long-term reproducibility across multiple fixture builds.

הערות תכנון
Antifuse FPGAs are one-time programmable: once the A54SX32A-TQG100A is programmed, the design cannot be changed and the device cannot be reworked. Always complete gate-level simulation, timing closure, and hardware verification on a development device (or in Libero simulation) before programming production units. Given the 12-week lead time and non-stocked status at major distributors (per Mouser, as of 2026-09-03), a programming error can cost months of schedule. Order spare programmed devices.
The 100-TQFP has 0.5 mm pin pitch with leads on four sides; use a land pattern per the Microchip SX-A datasheet package drawing and keep trace widths adequate for 81 potential I/O assignments. Decouple each supply pin with 0.1 uF ceramics placed within 2 mm of the pin, plus bulk capacitance near the device. Since I/O assignment is user-defined in Libero, group switching signals to minimize simultaneous switching noise on shared return paths. Verify power and ground pin locations against the datasheet TQ100 pin tables before routing.
Estimated: antifuse FPGAs draw no static configuration current (no SRAM to hold), so power is dominated by dynamic switching of the routed logic and I/O. Estimate total power in Microchip Libero's power calculator using your toggle rates and I/O loading before fixing the board's supply budget; do not size the regulator from worst-case datasheet numbers alone, as heavily utilized designs on the SX-A die can differ substantially from lightly used ones.
