A field-programmable gate array (FPGA) is a semiconductor device containing a matrix of configurable logic blocks (CLBs) and programmable interconnects that designers configure in the field, sitting within the broader hierarchy of programmable logic: FPGA -> programmable logic device -> digital IC. Unlike SRAM-based FPGAs, the Actel SX family uses antifuse programming elements that retain configuration permanently and are inherently resistant to configuration upset. Key features include the SX sea-of-modules architecture, which delivers application performance close to that of mask-programmed ASICs while eliminating NRE costs; a 0.35 um CMOS process; dual 3.3V/5V supply compatibility for legacy system integration; and up to 240 MHz system-level performance for compute-intensive glue logic, bus bridging, and state-machine functions. Technically, the sea-of-modules fabric provides high logic density per gate relative to coarser-grained SRAM architectures, with fast, predictable routing. The antifuse interconnect adds near-zero stray capacitance to switch paths, supporting the family's high toggle rates and low static power consumption. The 113 user I/O within the compact 144-lead low-profile quad flat package (0.5 mm terminal pitch) suits space-constrained industrial boards. Typical applications include industrial control and automation sequencing, telecommunications line-card glue logic, and aerospace/military subsystems requiring configuration immutability, where the A54SX32-TQG144I replaces multi-chip TTL/PLD solutions in a single device. Design consideration: the antifuse device is one-time programmable - final programming must occur at the production stage with verified design files, and JTAG-based programming equipment compatible with the Actel SX family is required. Plan the BOM accordingly since in-circuit design iterations require new devices.

An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a fabric of programmable logic blocks and interconnects that designers configure after manufacturing. Within the programmable-logic hierarchy - FPGA -> programmable logic device -> digital IC - antifuse FPGAs like the SX-A are one-time-programmable (OTP): configuration is permanently written, giving inherent resistance to configuration readback attacks and no need for an external configuration flash, which improves system reliability and security compared to SRAM FPGAs. Key features include the sea-of-modules architecture built from two logic module types: the C-cell (combinatorial) and R-cell (register), providing essentially lossless floorplan area utilization. The -1 speed grade balances performance and cost, the 256-FPBGA footprint supports high-density surface-mount assembly, and the wide 2.25V to 5.25V supply tolerance plus military-grade temperature rating make it suitable for harsh environments. RoHS3 compliance (the M suffix denotes moisture-sensitivity/lead-free flow per distributor listings) supports modern assembly processes. Architecturally, the SX-A covers the entire die with a grid of logic modules and routing, so virtually no chip area is lost to interconnect. The 32K-gate-class A54SX32A die (marketed at 48K system gates) integrates multiple glue-logic, interface, and control functions into a single low-cost chip, replacing multi-chip PAL/GAL/ASIC solutions and reducing board area, power, and BOM cost. Typical applications include aerospace and defense control logic, industrial automation controllers, communications interface bridging, and test equipment, where one-time programmability, instant-on startup, and tamper resistance matter more than reprogrammability. Design consideration: because SX-A devices are OTP, verify your design thoroughly in simulation (Libero SoC / Designer flow) before programming; there is no design iteration on the same silicon, so account for the approximately 20-week manufacturer lead time in your procurement plan.

Typical applications include glue-logic integration, bus interfacing, industrial control, telecommunications line-card functions, and military/aerospace designs that value the configuration security and instant-on behavior of antifuse FPGAs. A key design consideration: antifuse devices are one-time programmable, so debugging requires careful up-front simulation; prototype on a slower-speed or larger-density same-family device before committing the -1 speed grade. This page adds value beyond the datasheet by consolidating distributor pricing, stock levels, drop-in family alternatives, and procurement guidance in one place.
A54SX32A-1PQG208I - SX-A FPGA 48K Gates 208-PQFP | Microchip

Key features include 2880 CLBs, 174 user I/O pins, 2.5V core operation, and a -1 speed grade supporting toggle rates up to 278 MHz. The antifuse fabric provides low on-resistance interconnect and deterministic routing delays, while total static power is far lower than SRAM FPGAs of similar density, making the family attractive for power-sensitive, high-reliability designs. Technically, the SX-A architecture combines sea-of-modules logic with a three-level metal routing fabric on a 0.25 um CMOS process. The D-module (combinational) and R-module (register-capable) cells give an efficient mix for both datapath and control logic. Because the antifuse is programmed once, design changes require a new device - a deliberate trade of flexibility for security, cost, and reliability. Typical applications include industrial control and automation glue logic, communications interface bridging, aerospace and defense systems that benefit from configuration immunity, and medical equipment requiring stable single-chip logic integration. Design consideration: the 2.5V core requires a dedicated supply rail and correct power sequencing relative to I/O banks; plan the 208-pin PQFP land pattern and thermal relief early since the package is not drop-in compatible with other footprints. This page synthesizes distributor pricing, same-footprint alternatives, and practical design notes beyond what the manufacturer datasheet alone provides.

The Microchip Technology A54SX32A-1TQG100I is an SX-A family antifuse FPGA providing 48K system gates (32,000 typical gates, 1800 logic modules), 81 user I/Os, and system performance up to 278 MHz, housed in a 100-pin TQFP (TQG100) package with industrial temperature range of -40C to +85C and a 2.5V core supply. An FPGA (Field-Programmable Gate Array) is a type of programmable logic IC that lets designers implement custom digital circuits after manufacturing, sitting above CPLDs and below full-custom ASICs in the programmable logic hierarchy. The SX-A family uses Actel-derived antifuse programming technology, which is one-time programmable (OTP): configuration bits are permanent, giving inherent resistance to configuration readback attacks and no need for external configuration memory at power-up. Key features of the A54SX32A-1TQG100I include a 0.25 um process technology, a sea-of-modules architecture for high gate utilization, 2.5V low-power operation, and the speed grade -1 (fastest commercial bin in the family at 278 MHz toggle capability). Because the configuration is stored in antifuses rather than SRAM, the device powers up instantly with no configuration time and offers lower static power than SRAM FPGAs. Technically, the SX-A architecture combines combinational logic modules (C-cells) and register modules (R-cells) in a sea-of-modules fabric, with dedicated clock resources and embedded boundary-scan test support. The -1 speed grade maximizes combinational and register performance for timing-critical paths. Typical applications include industrial control and automation, communications and networking line cards, aerospace and defense systems where antifuse security and radiation tolerance heritage matter, and glue-logic integration replacing multiple discrete devices in a low-cost single-chip solution. Design consideration: because the device is one-time programmable, iterate designs in silicon-costly steps; verify timing closure thoroughly in Libero/Microchip design tools before programming, and reserve the -1 speed grade budget for genuinely critical paths.

A54SX32A-1TQG100M - 48K Gate FPGA 81 I/O TQFP-100 | Microchip
The Microchip Technology (Microsemi) A54SX32A-1TQG100M is an SX-A family antifuse field programmable gate array (FPGA) with 48,000 system gates, 81 user I/O, and a -1 speed grade, housed in a 100-pin TQFP (TQG100) surface-mount package. It operates from a 2.5V core supply (2.25V to 5.25V per distribution data) and is qualified across the -55C to +125C military temperature range, indicated by the M grade suffix. An FPGA (Field Programmable Gate Array) is a semiconductor device containing a matrix of configurable logic blocks and programmable interconnects that the designer wires together after manufacturing, sitting within the programmable logic hierarchy above CPLDs and below full-custom ASICs. The SX-A family uses Microsemi antifuse technology, in which programmed connections are permanent one-time links. This yields instant-on operation with no configuration PROM or boot time, high resistance to radiation-induced configuration upsets, and low long-term cost for volume production. Key features of the A54SX32A-1TQG100M include its sea-of-modules architecture built on 0.25 um CMOS processing, a maximum toggle rate of approximately 278 MHz, and 1,800 usable logic cells. The -1 speed grade denotes the base speed bin of the SX-A family; -2 and faster grades trade higher power for additional performance. The 100-pin TQFP package provides a 0.5 mm lead pitch in a 14 mm x 14 mm body suitable for cost-sensitive two-layer and four-layer boards. Because antifuse programming is one-time, designs are finalized by simulation and signed off before programming; this makes the family attractive for fixed-function replacements of gate arrays, glue logic consolidation, and defense/aerospace programs where the wide -55C to +125C temperature range and non-volatile, no-boot behavior are decisive. Typical applications include industrial control, avionics interfaces, communications line cards, and military equipment. Design consideration: the part is programmed once, so verify timing with Microchip Libero/Designer software at the -1 speed grade and reserve I/O margin, since no rework is possible after programming.

An FPGA (Field-Programmable Gate Array) is a semiconductor device containing programmable logic blocks and interconnects that designers configure after manufacturing. Within the programmable logic hierarchy, the A54SX32A sits in the mid-density class of one-time-programmable (OTP) antifuse FPGAs: FPGA -> programmable logic device (PLD) -> digital logic IC -> semiconductor. Unlike SRAM FPGAs, Actel antifuse devices retain their configuration permanently and require no external boot configuration ROM. Key features include a 0.25um CMOS antifuse process, clock speeds up to 278 MHz, low static power consumption typical of the SX-A family, and a low-cost single-chip integration path. The -1 speed grade is the fastest commercial grade in the SX32A lineup, and the 20x20 mm TQFP-144 body with 1.4 mm height suits surface-mount assembly without fine-pitch BGAs. Architecturally, the SX-A family uses a sea-of-modules fabric with combinational and sequential logic modules (C-cells and R-cells) connected by a segmented routing fabric programmed through antifuse links. This structure yields deterministic, low-jitter routing with interconnect delays comparable to gate arrays, making the family a low-risk ASIC or complex-PAL replacement. Typical applications include industrial control glue logic, communication bridging, state-machine integration, bus interfaces, and cost-sensitive system consolidation where a one-time-programmed configuration is a security or reliability benefit. Design consideration: antifuse devices are one-time programmable - prototype on compatible devices or use the Libero/Microsemi design flow with thorough simulation before committing, since design changes require a new device. Verify 2.5V supply rail sequencing and decouple each VCC pin.

FPGAs sit in the programmable logic hierarchy alongside CPLDs and ASICs, offering ASIC-like integration without the non-recurring engineering cost and long lead times of a custom mask-set device. Key features of this SX-A device include its 0.25 um CMOS antifuse process, which delivers radiation-tolerant-like nonvolatility and instant-on power-up with no external configuration PROM, and a supply range of 2.25V to 5.25V per distributor data, easing integration into legacy 3.3V and 5V systems. The 1 speed grade supports internal toggle rates up to 278 MHz per parametric listings. Architecturally, the SX-A family uses a sea-of-modules structure with fine-grained logic modules and fast, dedicated routing resources. The antifuse interconnect is programmed once at the factory or in-house using a programmer; it adds nanosecond-level routing delays and inherently resists bit-flip configuration corruption, a security and reliability advantage over SRAM-based FPGAs. Typical applications include industrial control and automation glue logic, communications bridging, aerospace and defense subsystems requiring instant-on and configuration security, and legacy design sustainment where Microsemi (now Microchip) Actel antifuse FPGAs were originally designed in. Design consideration: antifuse FPGAs are one-time programmable - exhaustively verify the design in simulation before programming production units, and reserve engineering spare capacity in the 1800-cell array for late fixes.

It operates from a single 2.5V core supply and is fabricated in a 0.25 um process, with lead-free/RoHS-compliant construction and tray packaging. An FPGA (field programmable gate array) is a semiconductor device containing a fabric of configurable logic blocks and programmable interconnects that the designer configures after manufacturing. Within the programmable logic hierarchy, the SX-A sits among antifuse-based, one-time-programmable FPGAs, positioned under the broader categories of programmable logic ICs and embedded processing hardware. Unlike SRAM FPGAs, antifuse devices such as the SX-A retain their configuration permanently and require no external boot ROM. Key features include the sea-of-modules architecture that reduces design time and cost, one-time-programmable antifuse technology that eliminates configuration storage and improves design security, and low power consumption relative to SRAM-based alternatives. The -1 speed grade supports system frequencies suitable for glue logic consolidation, bus bridging, and state-machine implementations, while the 113 available I/Os handle wide parallel interfaces. Technically, the SX-A fabric combines combinatorial modules with register-rich sequential modules, enabling efficient synthesis of both datapath and control logic. The 0.25 um process balances speed and cost, and the 2.5V core keeps dynamic power low. Designers typically access the device via Microchip (Actel) Designer software with synthesis from standard HDL flows. Typical applications include industrial control, communications bridging, aerospace and defense boards that value the security of antifuse configuration, and obsolete-system lifecycle extensions where the SX32/SX-A footprint must be maintained. A key design consideration: antifuse FPGAs are one-time programmable, so verify pinout, I/O standards, and timing constraints thoroughly before programming.

A54SX32A-2BGG329 - 48K Gate FPGA, 313MHz | Microchip Technology
The Microchip Technology A54SX32A-2BGG329 (formerly Actel/Microsemi) is a 48,000-system-gate antifuse FPGA from the SX-A family, delivering 2,880 logic cells, up to 249 user I/Os, and a maximum toggle rate of 313 MHz, housed in a 329-ball BGA (BGG329) package. The -2 speed grade device operates from a single 2.5V core supply and is fabricated on a 0.25 um CMOS process. An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a sea of programmable logic blocks and interconnects that designers configure after manufacturing. The SX-A family belongs to the antifuse FPGA category: unlike SRAM-based FPGAs, its interconnect elements are permanently programmed at the factory or in the lab, so the configuration is retained at power-up without any external boot PROM, improving security and reducing BOM count in the power-management hierarchy of a system design. Key features of the A54SX32A-2BGG329 include 48K system gates (32K raw gates, 2,880 logic cells) for integrating glue logic, bus interfaces, and state machines into a single chip; 249 user I/Os in the 329-ball BGA, supporting high-pin-count board layouts; and the -2 speed grade supporting 313 MHz internal performance. The antifuse architecture contributes inherently low power, high immunity to configuration readback, and essentially non-volatile, single-chip integration, which Microchip positions as lowering the performance premium versus competing architectures. Technically, the device uses a sea-of-modules architecture with repeated logic modules (C-cells and R-cells) and a routing fabric programmed by antifuse elements. Because the bitstream is physically burned in, there is no configuration time at power-up and no external configuration device to attack or corrupt, a property valued in defense, avionics, and industrial control where design protection matters. Typical applications include industrial automation and control, communications and networking line cards, test and measurement instrumentation, aerospace and defense subsystems, and bridging/glue logic for processors and ASICs. The large I/O count and deterministic power-up suit designs requiring many interface signals to be live immediately at reset. A key design consideration: antifuse FPGAs are one-time programmable. Unlike SRAM FPGAs, you cannot reconfigure the same device; design iteration requires new parts, so verification in simulation and timing closure with the Libero/Designer flow should be complete before programming production units.

It operates from a 2.25V to 5.25V mixed supply environment per distributor data and a commercial temperature range of 0C to +70C. An antifuse FPGA is a type of field-programmable gate array whose interconnects are permanently programmed at power-up of the configuration step rather than stored in SRAM. Unlike SRAM-based FPGAs, antifuse devices are non-volatile, require no external configuration ROM, and are inherently resistant to configuration upset, making them a member of the broader programmable logic and power/cost-sensitive ASIC- replacement hierarchy. The SX-A family targets designers who need one-time-programmable logic integration at ASIC-like unit cost. Key features of the A54SX32A-2FGG256 include 48K system gates (approximately 1,800 logic cells on a 0.25 um antifuse process per FindIC data), 203 available user I/Os in the 256-FBGA package, a -2 speed grade for mid-to-high-speed glueless integration, and RoHS3-compliant surface-mount assembly. Distributed routing and dedicated clock resources support synchronous designs without external glue logic. Technically, the SX-A architecture uses a sea-of-modules fabric with combinational and sequential modules connected by a program-once antifuse interconnect matrix. Because configuration is hard-wired, there is no configuration readback path, which supports designs where bitstream security matters. The 0.25 um process yields predictable timing, and the -2 grade represents the standard commercial speed bin for this family. Typical applications include industrial control and automation glue logic, telecommunications line-card interface bridging, defense and avionics legacy-design sustainment, and ASIC prototype or low-volume production integration where a single-chip solution replaces multiple discrete logic devices. Design consideration: as a one-time-programmable device, functional changes require new silicon, so lock down the design and verify timing with Microchip Libero/Designer software before committing to programming; the commercial 0C to +70C rating also excludes most automotive and extended-temperature industrial deployments.

Key differentiating features of the A54SX32A-2FGG256I include its antifuse interconnect architecture, which is non-volatile and inherently immune to configuration-bit upsets, low static power typical of 2.5 V 0.25 um CMOS process technology, and no external configuration PROM requirement - the device is live and configured at power-up. With 2880 logic cells (approximately 48,000 equivalent system gates), it integrates glue logic, bus interfaces, state machines, and control functions that previously required multiple TTL/PLD devices into a single low-cost chip. Technical depth: the SX-A architecture combines logic modules with dedicated routing channels, achieving predictable, low-skew timing. The 0.25 um CMOS antifuse process gives very low interconnect parasitic capacitance versus SRAM FPGAs of the era, supporting system performance up to 313 MHz toggle rates while minimizing dynamic power. The 256-ball FBGA provides 203 flexible user I/O with industry-standard 2.5 V/3.3 V-compatible I/O banks and surface-mount reflow assembly. Typical applications include industrial control and automation boards, telecommunications line cards, military/aerospace upgrade programs where OTP configuration security matters, embedded glue-logic consolidation, and legacy system life-extension designs that must remain sourced for years. Design consideration: because the device is one-time programmable, verify timing closure and pin assignment in Libero SoC before programming - there is no rework path after antifuse programming, so budget a small pilot run of programmed units for validation.

An FPGA (Field-Programmable Gate Array) is a semiconductor device that implements custom digital logic through programmable interconnect and configurable logic blocks. Within the programmable logic hierarchy, the A54SX32A belongs to the one-time-programmable antifuse FPGA category, positioned under FPGAs > programmable logic ICs > digital logic semiconductors. The SX-A family uses a sea-of-modules architecture in which the chip floor is a dense grid of logic modules, minimizing area lost to routing and enabling high gate utilization at low cost. Key features of the A54SX32A-2FGG484 include 0.25 um CMOS antifuse technology, 2.5 V core operation with support for 2.5 V, 3.3 V, and 5 V compatible I/O standards across the SX-A family, speed grade -2 timing, and a 484-ball FBGA footprint shared across the SX32A/SX72A density range. The antifuse interconnect is non-volatile and inherently single-chip: no external configuration PROM or boot sequence is required, which reduces BOM cost, board area, and configuration-bitstream security exposure compared with SRAM FPGAs. Architecturally, the device combines two logic module types: C-cells (combinatorial logic modules) and R-cells (register cells), embedded in a segmented routing fabric. Because antifuse links are programmed once at the factory-level programming stage, the device exhibits low static power, deterministic interconnect capacitance, and immunity to configuration upsets, making it attractive in harsh environments. Typical applications include industrial control and automation logic, telecommunications line-card glue logic and protocol bridging, aerospace and defense data paths, and medical instrumentation where single-chip integration replaces multi-chip ASSP and discrete logic solutions. Design consideration: because the SX-A is one-time programmable, prototype on the larger A54SX72A same-footprint device first and lock the design before committing programming; also budget I/O bank voltage selection (2.5/3.3/5 V) at layout time.
