A54SX32A-PQG208A - 48K Gate SX-A FPGA, 208-PQFP | Microchip
The Microchip Technology A54SX32A-PQG208A is a 48,000-system-gate antifuse FPGA from the SX-A family, delivering 174 user I/O, 238 MHz system performance, and 1.2 ns register-to-register timing in a 208-pin PQFP (BFQFP) surface-mount package operating at a nominal 2.5V core supply. An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a fabric of programmable logic blocks and interconnect that designers configure after manufacturing. Within the programmable logic hierarchy, the A54SX32A belongs to the one-time-programmable antifuse FPGA category, positioned above CPLDs in logic density and below SRAM FPGAs in reconfigurability. Its "sea-of-modules" architecture tiles the die with combinatorial cells (C-cells) and register cells (R-cells) with virtually no die area lost to routing. Key features include approximately 48,000 system gates (32,000 typical usable), 2880 logic modules, and 0.25 um antifuse technology. Because configuration is stored in antifuse elements rather than SRAM, the device is inherently secure against bitstream extraction and needs no external configuration ROM, reducing bill-of-materials cost and board complexity. Technically, the SX-A architecture achieves high routing efficiency through its module grid, supporting toggle rates up to 238 MHz with deterministic 1.2 ns pin-to-pin routing delays that do not vary significantly with placement. The antifuse switch adds near-zero parasitic capacitance, contributing to both speed and low static power consumption compared with SRAM-based alternatives of the same era. Typical applications include industrial control and automation logic, military and communications protocol glue logic, bridge functions between microprocessors and custom ASICs, and high-reliability single-chip system integration where configuration data must not be readable. Design consideration: as a one-time-programmable device, prototype iteratively in lower-cost family members before programming production parts; verify supply sequencing and 2.25V-2.75V core tolerance against your power tree.

A54SX32A-PQG208M - 32K-Gate Antifuse FPGA, 208-PQFP | Microchip
The Microchip Technology (Microsemi/Actel) A54SX32A-PQG208M is a 32,000-gate antifuse FPGA from the SX-A family with 1,800 logic modules, 174 user I/Os, and a maximum toggle frequency of 238 MHz, housed in a 208-pin plastic quad flat pack (PQFP, 28x28 mm, 0.5 mm pitch) and qualified for the military temperature range of -55C to +125C. The M suffix denotes the extended military temperature grade. An antifuse FPGA is a one-time-programmable (OTP) programmable logic device in which programming forms permanent low-resistance interconnects. Unlike SRAM FPGAs, an antifuse device retains its configuration through power cycles without an external configuration flash, offers inherent resistance to radiation-induced configuration upsets, and presents no bitstream to steal in the field - a hierarchy of benefits that places the SX-A among the most trusted families for high-reliability, security-sensitive systems. Key features include the sea-of-modules architecture built from combinatorial C-cells and register R-cells, 0.25 um CMOS antifuse technology, a 2.5 V core supply, and combinational logic speeds that support system clocks well above 100 MHz. The 174 available I/Os support both 5 V-compatible and 3.3 V signaling options, easing integration into mixed-voltage legacy boards. Architecturally, the die floor is covered with a dense grid of logic modules with virtually no area lost to routing channels; a rich hierarchical routing fabric connects module, cluster, and array levels. Timing is deterministic because routing is fixed after place-and-route, simplifying worst-case design sign-off for mil/aero programs. Typical applications include avionics and space control logic, military communications, industrial glue logic integration, and obsolescence-driven redesigns consolidating multiple ASICs or PAL/GAL devices into a single chip. Design consideration: because the device is OTP, verify the full netlist in simulation and, where possible, in the companion -A or commercial speed-grade silicon before committing military-grade units to programming.

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.

Fabricated on a 0.25 um CMOS process and operating from a nominal 2.5 V supply, it supports toggle rates up to 238 MHz, making it one of the highest-performance low-cost FPGAs of its class. An antifuse FPGA is a field-programmable gate array whose interconnect is permanently programmed at power-up by blowing one-time-programmable antifuse elements. Unlike SRAM-based FPGAs, antifuse devices need no configuration ROM, retain their configuration through power cycles, exhibit low net capacitance for high routing speed, and resist bitstream readback, providing inherent design security. Within the programmable logic hierarchy, the A54SX32A sits in the mid-range of the SX-A family (8K to 72K gates) alongside predecessors such as the SX family A54SX32. Key features include 2,880 logic modules (up to 2,012 dedicated flip-flops), 81 user I/O on the TQG100 package with 360 I/O available in larger packages, a sea-of-modules architecture for predictable timing, and single-chip integration that eliminates configuration devices. The one-time-programmable antifuse interconnect delivers low junction capacitance, reduced dynamic power, and strong IP protection because the programmed netlist cannot be extracted from the die. The device combines performance, security, and low power in a low-cost single-chip solution. The 0.25 um CMOS process and antifuse fabric enable internal frequencies competitive with much larger SRAM FPGAs, while typical static current remains in the low milliamp range. Supply operation is 2.375 V to 2.625 V nominal 2.5 V core with 3.3 V I/O support, per Microchip family documentation. Typical applications include industrial control, telecommunications line cards, glueless bus bridging, military/aerospace logic replacement (the family is widely used in long-lifecycle systems), and ASIC prototype replacement where design security matters. The M suffix denotes RoHS-compliant, lead-free packaging for new designs. Design consideration: antifuse programming is irreversible, so verify the design fully in simulation and, where possible, use the speed-grade-compatible commercial variants for prototyping before committing production silicon. Pin assignments should also reserve margin because one-time programming forbids later re-mapping.

With 113 user I/O in the 144-TQFP, the device supports a wide range of board-level interfaces, and the 'A' automotive grade suffix and 'TQG144A' ordering code denote the automotive temperature-range tray-packaged variant. Architecturally, SX-A devices use a sea-of-modules fabric built around combinatorial C-cells and register-rich R-cells, enabling both fast combinational decoding and pipelined sequential logic. The antifuse interconnect provides very low net capacitance compared with SRAM switch technology, which is why this 238 MHz rating was competitive for its generation and why signal integrity in radix-based routing remains predictable and timing-closure friendly. Typical applications include industrial control and automation sequencing, glueless bridge logic between legacy processors and modern peripherals, aerospace and defense systems that value the configuration security of antifuse technology, and automotive electronic control units - a use case directly supported by the automotive-grade A54SX32A-TQG144A variant. When designing with this device, plan your design flow around the Libero SoC suite (or legacy Actel Designer tools) and remember that antifuse programming is irreversible - prototype on a larger SX-A device or use abundant floorplanning margin before committing. This page synthesizes distributor pricing, drop-in alternatives within the same 144-TQFP footprint, and practical design notes not found in the manufacturer datasheet, giving engineers a single verifiable reference point.

An antifuse FPGA is a field-programmable gate array whose interconnect switches are one-time-programmable antifuse elements rather than SRAM configuration cells. Within the programmable logic hierarchy (FPGA -> programmable logic device -> programmable semiconductor), antifuse devices are nonvolatile at power-up, immune to configuration readback, and exhibit very low routing capacitance, which yields the high speed and low power the SX-A family is known for. Key features include a sea-of-modules architecture built from C-cell (combinatorial) and R-cell (register) modules, 2880 configurable logic modules per Microchip USA listing, 113 user I/O on the 144-TQFP package, and flexible 2.5 V, 3.3 V, and 5 V I/O operation. Fast pin-to-pin timing of 3.7 ns clock-to-out, 0.1 ns input setup, and 0.25 ns clock skew supports 66 MHz PCI-class designs, with 100% resource utilization and 100% pin locking. The SX-A architecture covers the entire die with a grid of logic modules, so virtually no chip area is lost to interconnect - a major reason the family achieves high gate utilization and predictable timing. Fabricated on 0.22 um / 0.25 um CMOS antifuse process technology, the device is single-chip, low-power, and secure against design extraction, making it attractive for cost- and security-sensitive integration. Typical applications include industrial control and automation logic, communications and networking glue logic, aerospace and defense systems that need power-up nonvolatile and configuration-security, and PCI bridge or bus-interface designs. Design consideration: antifuse devices are one-time programmable - verify your netlist thoroughly in simulation before programming, and select the correct speed grade (IX53 = industrial temperature) since rework after programming is impossible.

An FPGA (Field Programmable Gate Array) is a class of programmable logic IC that lets designers implement custom digital circuits in hardware after manufacturing, sitting in the system hierarchy between fixed-function ASICs and general-purpose processors. The SX-A family uses a sea-of-modules architecture in which the entire die floor is covered by a grid of logic modules with virtually no area lost to routing, combining the density of ASICs with the flexibility of programmable logic. Key features include 320 MHz internal performance, 3.7 ns pin-to-pin clock-to-output, 0.1 ns input setup time, and 0.25 ns clock skew, enabling single-chip integration of glue logic, bus interfaces, and control functions that previously required multiple devices. The family provides two logic module types: the register cell (R-cell) and the combinatorial cell (C-cell), supporting 100% resource utilization with 100% pin locking. Architecturally, the sea-of-modules structure simplifies timing closure and dramatically reduces design cost, power consumption, and time to market for performance-intensive applications. The antifuse-based programming of the SX-A family makes it suitable where configuration security and immediate power-up operation matter. Typical applications include industrial control and automation, communications and networking equipment, 5G-adjacent infrastructure glue logic, and aerospace/defense program replacements for end-of-life logic, where the industrial temperature grade (I suffix) is required.

An antifuse FPGA is a one-time-programmable (OTP) programmable logic device in which permanent low-resistance interconnects are formed at programming. Compared with SRAM-based FPGAs, antifuse devices power up instantly with no configuration PROM, offer inherent resistance to radiation-induced configuration upset, and provide strong design security because the programmed netlist cannot be read back. Within the programmable logic hierarchy, the SX-A family sits among high-speed, low-power OTP FPGAs for aerospace, defense, and industrial systems. Key features include a segmented routing architecture with four dedicated global/quadrant clock networks (CLKA, CLKB, and QCLK circuits), switching performance up to 217 MHz for the SX-A family, and multi-voltage I/O configurable from 2.25V to 5.25V, allowing direct interfacing with 5V legacy buses and 3.3V or 2.5V logic. The fabrication is a 0.22um/0.25um CMOS antifuse process. The -1 speed grade suffix denotes the fastest bin of the 72K-gate SX72A device; the B suffix denotes the military B-grade screening over the full -55C to +125C temperature range, and the ceramic CQFP hermetic package supports high-reliability assembly flows. Typical applications include MIL-STD-1553 and ARINC bus glue logic, satellite and avionics payload control, secure single-chip integration of ASIC prototypes, and industrial control where instant-on configuration and configuration-readback security are required. When designing with this device, plan pin assignments early: antifuse routing flexibility is lower than SRAM FPGAs, so aggressive pin locking can degrade routability and timing. Use the quadrant clock resources for high-fanout signals to preserve general routing.

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. Within the programmable logic hierarchy, the SX-A belongs to the antifuse FPGA subcategory: one-time programmable devices whose interconnect is permanently set at programming time, as opposed to SRAM-based FPGAs that are reconfigurable and require an external configuration memory. Antifuse FPGAs are favored where nonvolatility, security against bitstream extraction, instant-on behavior, and low static power are more important than in-field reprogrammability. Key features of the A54SX72A-1CQ256 include 72,000 gates (equivalent to 4,024 logic cells) and up to 108,000 usable system gates, a maximum toggle frequency of 250 MHz, and 203 user I/Os in the ceramic CQFP package. The ceramic package with tie bar provides superior moisture immunity and thermal performance compared to plastic packages, supporting demanding environments and simplified rework. Speed grade 1 denotes the standard speed bin of the SX-A family, and the device operates over a commercial 0 C to +70 C temperature range. Architecturally, the SX-A family uses a sea-of-modules structure with dedicated FIFO-like logic modules and dedicated high-speed carry logic, supported by three types of clock resources: two hard-wired global clocks (CLKA, CLKB) and quadrant clocks (QCLK) for localized, low-skew clocking, as described in Microchip's SX-A family datasheet. The 0.25 um antifuse interconnect delivers deterministic, low-jitter routing well suited to high-performance state machines, bus interfaces, and glueless integration of multiple logic functions into a single low-cost chip. Typical applications include industrial control and automation logic consolidation, military and aerospace subsystems that leverage ceramic packaging and antifuse security, telecommunications line-card control, and legacy system life-extension where a pin-identical ceramic-package FPGA is already qualified on the board. When designing with this device, note the single 2.5 V core supply requirement and verify power sequencing against the SX-A datasheet; also plan programming logistics, since antifuse devices are one-time programmable and require a programmer-compatible design flow (Libero SoC) before board assembly.

It operates from a 2.25V to 5.25V supply and carries the commercial temperature suffix. An antifuse FPGA is a field-programmable gate array whose interconnect switches are permanently programmed once, rather than stored in configuration memory. In the programmable logic hierarchy, the SX-A sits under FPGA -> field-programmable logic -> programmable SoC/ASIC prototyping devices. Because the antifuse programming is non-volatile and inherently unalterable, these devices deliver ASIC-like security, instant power-up, and no external configuration PROM, making them a single-chip replacement for multi-chip glue-logic implementations. Key features of the A54SX72A include the largest density in the SX-A family at 108K system gates, a sea-of-modules architecture with fine-grained logic modules, quadrant clocking resources (CLKA, CLKB and QCLK networks) that simplify large-design clock distribution, and a ceramic package suited to long-lifecycle and harsh-environment programs. Architecturally, the SX-A uses a two-module logic cell (a C-cell for combinational logic and an S-cell for sequential elements), giving high effective logic utilization per gate. Routing is dominated by short and long antifuse interconnect segments, achieving fast, predictable delays suited to state machines, bus interfaces, and datapath functions. Typical applications include industrial control and automation, communications and networking line cards, military and aerospace upgrades of legacy designs, and ASIC prototyping or bridge logic where single-chip integration reduces BOM cost. Design-wise, program the device once and verify the fuse map in Libero SoC before programming, since antifuse programming is irreversible; budget I/O assignments across the four quadrants to use the quadrant clocks effectively. This page adds value beyond the datasheet by consolidating distributor availability, same-package drop-in variants, and engineering design notes in one place.

An antifuse FPGA is a type of field-programmable gate array in which the interconnect is permanently configured at programming time by blowing microscopic antifuse links. Unlike SRAM-based FPGAs, antifuse devices retain their configuration through power cycles without any external boot memory, offer lower static power, and provide higher resistance to configuration readback - a key advantage in security-conscious and high-reliability systems. Within the programmable logic hierarchy, the SX-A family sits under Actel-origin (now Microchip) antifuse FPGAs, positioned as low-cost, single-chip integration solutions. Key features of the A54SX72A include a 0.25 um process technology, multiple global and quadrant clock networks (CLKA, CLKB, and QCLK resources), and speeds up to 250 MHz as reported for the -1 speed grade. The M suffix in the MPN denotes a moisture-sensitive/lead-free commercial qualification variant of the ceramic quad flat pack. Architecturally, the device uses Actel's multiplexer-based combinatorial logic cells organized into clusters, with four layers of metal interconnect routing resources located between the top two metal layers for efficient silicon use, as described in the SX-A family datasheet. Dedicated quadrant clocking in the 72K-gate A54SX72A supports multiple independent clock domains. Typical applications include glueless bus-interface integration, industrial control, communications line cards, test equipment, and defense/aerospace systems requiring one-time-programmable, configuration-store-free logic. Designers should note the commercial operating range of 0C to +70C and plan the 2.5V core rail accordingly; once programmed, the antifuse fabric cannot be reprogrammed, so design verification must be complete before device programming.

The device operates from a single 2.5 V supply and carries speed grade -1. An antifuse FPGA is a type of field-programmable gate array in which the programmable interconnect is formed by one-time-programmable antifuse elements rather than SRAM configuration cells. Within the programmable logic hierarchy, the A54SX72A sits in the Actel (now Microchip) antifuse FPGA branch: FPGA -> one-time-programmable FPGA -> antifuse FPGA -> SX-A family. Because the configuration is hard-wired at programming, antifuse FPGAs are non-volatile, inherently secure, immune to configuration readback, and require no external configuration PROM at power-up. Key features include the 108K gate organization (72,000 typical gates available for design implementation), 250 MHz system performance, and single-chip integration that eliminates external boot devices. The SX-A architecture locates routing interconnect between the top two metal layers, providing efficient silicon utilization and predictable timing for high-throughput designs. Technically, the A54SX72A uses a sea-of-modules CMOS fabric with fast, dedicated carry logic and registers-per-module ratios that support pipelined datapaths. The antifuse interconnect provides low junction capacitance on switched nodes relative to SRAM switch fabrics, contributing to the family's combination of speed and low static power. Typical applications include industrial control, communications and networking line cards, avionics and high-reliability systems requiring configuration security, and glue-logic consolidation where multiple ASSPs or ASIC prototypes are merged into one low-cost, single-chip solution. A key design consideration is that antifuse devices are one-time-programmable: design changes require a new physical device, so complete functional simulation and timing verification in Libero/Designer software are essential before programming.

An antifuse FPGA is a field-programmable gate array whose interconnect configuration is permanently set at power-up programming time via antifuse elements, unlike SRAM FPGAs that reload configuration from external memory at every boot. In the programmable logic hierarchy, the A54SX72A sits within the FPGA family tree as a one-time-programmable (OTP), non-volatile device, making it immune to configuration readback, bit-stream interception, and radiation-induced configuration upsets. Key differentiating features include zero configuration time (instant-on at power-up), no external configuration PROM or boot flash requirement, low static power typical of 2.5V 0.25um CMOS, and inherent design security because the programmed netlist physically exists in the silicon antifuse array. The SX-A architecture provides a sea-of-modules fabric with combinational and sequential logic modules and rich routing resources. Technically, the device is fabricated on a 0.25um/0.22um CMOS process and supports system clock rates up to 250 MHz. Global and quadrant clock networks (CLKA, CLKB, and QCLK) distribute low-skew clocks across the die, supporting both single-domain and partitioned clocking schemes per Microchip application notes. Typical applications include aerospace and industrial control logic integration, bridge and interface logic, bus controllers, glueless processor support, and secure single-chip integration of multiple ASSP functions where configuration volatility is unacceptable. A key design consideration: because the device is one-time-programmable, final pinout and routing must be fully verified in the Libero/M Designer flow before programming, and engineering prototype wafers should be used during iterative development.

The Microchip Technology A54SX72A-1FG256M is an SX-A family antifuse FPGA providing 108,000 system gates (72,000 typical gates, 4,024 module cells), 203 user I/O, and system performance up to 250 MHz, housed in a 256-ball FBGA (17x17 mm) package with a speed grade of -1 and a wide -55C to +125C (TC) operating temperature range. An antifuse FPGA is a type of field-programmable gate array in which the interconnect programming elements are one-time-programmable antifuse cells. Unlike SRAM-based FPGAs, an antifuse FPGA requires no external configuration ROM, configures in milliseconds at power-up, and offers inherently high resistance to radiation and bit-stream theft, making the technology a subset of one-time-programmable programmable logic within the broader power-management-free, low-risk FPGA hierarchy. Key features include a 0.25 um process operating from a 2.5V core supply, single-chip integration that removes the cost of configuration devices, and the security and low power inherent to antifuse interconnect. The 203 available I/O support multiple voltage-referenced standards, and the -1 speed grade balances performance with availability for long-lifecycle programs. Architecturally, the SX-A fabric combines C-cells (combinatorial logic) and R-cells (sequential logic) with a segmented routing mesh programmed by metal-to-metal antifuse links, delivering fast, deterministic interconnect delays suitable for high-speed state machines and glue logic consolidation. Typical applications include aerospace and defense logic replacement, industrial control, communications line cards, and obsolescence mitigation where a one-time-programmable, configuration-free FPGA is preferred. Design consideration: as a one-time-programmable device, verify the design fully in simulation and, where practical, prototype on the -2 speed grade or PQ208 variant before committing production devices.

A54SX72A-1FG484 - 72K Gate Antifuse FPGA, 484-BGA | Microchip
The Microchip Technology A54SX72A-1FG484 is a high-density antifuse field programmable gate array (FPGA) from the SX-A family, offering 108,000 equivalent system gates (72,000 typical gates), 6036 configurable logic modules, a toggle-rate performance of 250 MHz, and 360 user I/Os in a 484-ball Fine-Pitch Ball Grid Array (FBGA) with 1 mm ball pitch. An antifuse FPGA is a one-time-programmable (OTP) programmable logic device in which permanent interconnects are formed at programming time. Within the programmable logic hierarchy (FPGA -> programmable logic device -> digital IC -> semiconductor), antifuse devices occupy the non-volatile, single-chip niche: unlike SRAM FPGAs they need no configuration PROM, and unlike flash FPGAs their programming is irreversible, which inherently protects the bitstream from readback. Key features of the A54SX72A include the SX-A sea-of-modules architecture with 0.25 um/0.22 um CMOS technology, a 2.5V core supply (supply range 2.25V to 5.25V per family data for I/O configurations), quadrant clocking with global CLKA/CLKB and four quadrant clock networks, and a 1.3 ns logic-module clock-to-out figure cited by distributor data. The combination of 250 MHz toggle rate and OTP security makes the family attractive where design protection matters. The architecture is based on the Actel-origin SX-A sea-of-modules fabric, combining C-cells (combinational) and S-cells (sequential) for efficient mapping of both random logic and registered pipelines, with dedicated routing for carry chains and quadrant clocks. Design entry and compilation use the Actel/Microchip Libero or Designer software flow. Typical applications include industrial control and automation, networking line cards, secure single-chip glueless integration, military/aerospace payloads requiring configuration-free power-up, and test instrumentation. Integrating multiple ASSP and glue-logic functions into one chip cuts board cost, inventory, and failure points. Design consideration: because the device is one-time programmable, prototype with the larger-speed-grade or de-rate timing margins before committing; also confirm the leaded (tin-lead, tin-lead for the -1FG484 suffix) ball finish against your assembly RoHS exemption strategy.

The -1 speed grade and industrial (I) temperature rating make it suited for harsh-environment embedded systems. An antifuse FPGA is a type of field-programmable gate array whose interconnects are permanently configured at power-up by blowing programmable antifuse links. Unlike SRAM-based FPGAs, antifuse devices are non-volatile, require no external configuration memory, and are inherently resistant to configuration bitstream readback attacks, which places them in the one-time-programmable (OTP) programmable logic category alongside CPLDs and flash-based FPGAs. Key features of the A54SX72A include a 0.25um/0.22um CMOS process, low static power consumption typical of 2.5V antifuse architectures, dedicated global and quadrant clock networks (CLKA, CLKB, and QCLK) for low-skew clock distribution, and a sea-of-modules routing fabric that provides high gate utilization. The 360 available I/Os support a wide range of interface standards at 2.5V logic levels. Architecturally, the SX-A family combines C-cell combinational logic modules with R-cell sequential modules, enabling efficient implementation of both wide combinational functions and registered pipelines. The antifuse interconnect provides deterministic, low-capacitance routing that supports the family's 250 MHz performance rating while keeping power draw low compared to SRAM FPGA alternatives. Typical applications include industrial control and automation, secure military and aerospace logic integration, telecommunications line-card glue logic, and single-chip integration of multiple ASIC/SSI/MSI functions where configuration readback protection and instant-on operation matter. A key design consideration: antifuse devices are one-time programmable, so prototype thoroughly in simulation and verify pinout assignments before programming; there is no rework path after programming errors.

An antifuse FPGA is a type of field-programmable gate array in which the interconnect is programmed permanently by blowing microscopic antifuse links at power-programming time. Unlike SRAM-based FPGAs from the broader programmable logic family, antifuse devices are non-volatile, configuration is retained without an external boot flash, and the programmed connections are inherently resistant to readout, making this programmable logic category attractive for secure, single-chip integration in defense, avionics, and industrial systems. Key differentiating specifications include 0.25 um / 0.22 um CMOS antifuse process technology, support for 2.5 V, 3.3 V, and 5 V I/O signaling on a 2.5 V core supply, and the -1 speed grade within the SX-A speed family. The device supports up to 100% resource utilization and 100% pin locking with deterministic, user-controllable timing, which simplifies timing closure at high logic occupancy. Architecturally, the SX-A fabric is organized as a sea-of-modules with 6,036 combinatorial logic cells (CLBs per FindIC cross-reference data) and dedicated registers, delivering predictable routing delays because antifuse interconnect is fixed once programmed. Security features include Actel Secure Programming Technology with FuseLock, which prevents reverse engineering of the programmed design, and boundary-scan testing in compliance with IEEE 1149.1 (JTAG). In-system diagnostic and verification is performed with the Silicon Explorer II tool. Typical applications include military and avionics glue-logic integration, secure industrial control, communications bridging, and legacy socket maintenance where a non-volatile, single-chip solution replaces multiple MSI/LSI devices. Design consideration: because antifuse programming is one-time and irreversible, verify the full netlist in simulation and with Silicon Explorer II diagnostics before committing the device; the -1 speed grade limits timing headroom versus the faster -2 grade.

Key features include a 2.5V core supply, system performance up to 250 MHz, single-chip integration that eliminates external configuration PROMs, and the inherent security and low power of antifuse technology. Because configuration bits are burned into the silicon, the bitstream cannot be read back, providing a higher level of design IP protection than volatile architectures. The SX-A architecture uses a sea-of-modules structure with logic modules (C-cells) and routing resources tuned for high-speed combinational and sequential functions. The 0.25 um process balances speed, power, and cost, making the family a cost-effective single-chip integration path for glue logic consolidation and system functions that would otherwise require multiple devices. Typical applications include industrial control and automation logic, telecommunications and networking line-card functions, military/aerospace-program legacy designs, and general high-speed glue-logic integration where non-volatile, secure, single-chip programmable logic is required. Design consideration: antifuse devices are one-time programmable, so verify the design fully in simulation and, where possible, on a lower-cost family member before committing production units; budget design iterations accordingly.

A54SX72A-1FGG256M - 108K Gate SX-A FPGA | Microchip
The Microchip Technology A54SX72A-1FGG256M is an SX-A antifuse field-programmable gate array (FPGA) that provides 108,000 system gates, 203 user I/O pins, and a 250 MHz maximum clock in its -1 speed grade, housed in a 256-ball fine-pitch BGA (256-FPBGA, 17x17 mm) package. An FPGA is a semiconductor logic device whose internal gate network can be configured after manufacturing. The SX-A family from Microchip uses antifuse programming elements, so configuration is non-volatile and one-time programmable. In the system hierarchy, this part can be classified as FPGA, programmable logic device, embedded logic chip, and ultimately an integrated circuit. Unlike SRAM FPGAs, antifuse FPGAs require no external boot PROM or SPI flash, eliminating configuration-load failures at startup, improving instant-on response, and reducing BOM area. Key features include 108,000 system gates, 203 user I/Os, 0.25 µm antifuse CMOS at a 2.5 V core, military case-temperature range of -55°C to +125°C, and ROHS3-compliant FGG package finish. The -1 speed grade is listed at 250 MHz by distributor data, making the device suitable for timing-intensive defense and aerospace logic. The package is a 256-FPBGA, delivered in tray packaging, and Microchip USA reports an active lifecycle status with a 20-week manufacturer lead time. Technically, SX-A antifuse interconnect is physically programmed during manufacturing, producing predictable low-impedance routing with low power and strong security. The FPGA is live immediately at power-up and has no loadable bitstream to intercept, which reduces the risk of reverse engineering compared with SRAM-based FPGAs that require external configuration memory. Typical applications include military avionics, secure networking and encryption, industrial control, sensor aggregation, and high-reliability instrumentation. The 108K-system-gate density lets designers consolidate multiple discrete logic and interface functions onto a single-chip solution, lowering board area and total component count. Because the SX-A device is one-time programmable, complete timing closure and board-level simulation must be finished before programming. Designers should also verify the 256-ball map in the SX-A family datasheet before PCB layout and should confirm the I/O supply strategy because several I/O banks may operate over different voltage ranges.

It operates from a 2.5V core supply on a 0.25 um CMOS process with speed grade -1. An antifuse FPGA is a field-programmable gate array whose interconnect switches are permanently programmed at power-up programming time, unlike SRAM-based FPGAs that reload configuration from external memory on every power cycle. Within the programmable logic hierarchy, the SX-A sits in the one-time-programmable (OTP) FPGA category, providing non-volatile configuration without a configuration PROM, which improves design security and reduces board-level component count. Key features include 108K usable system gates, deterministic sub-nanoseand-class antifuse interconnect delays that do not vary with routing congestion, quadrant and global clocking resources (CLKA, CLKB, and QCLK networks), and a low-power 2.5V core. The 484-ball FGG484 package maximizes I/O availability at 360 user pins, supporting wide bus interfaces and parallel data paths in a single chip. The SX-A architecture is built from Combinatorial Modules and Register Modules organized in clusters, delivering fast, predictable carry logic for arithmetic functions. Because configuration is stored in antifuse elements, the bitstream is not externally readable, giving inherent resistance to design cloning compared with SRAM FPGAs. Typical applications include industrial control and automation, communications and networking line cards, military and aerospace boards requiring one-time-programmable security, medical equipment, and glue-logic integration that replaces multiple ASIC/SSI devices for cost savings. When designing with the A54SX72A, plan the design flow in Libero SoC (or legacy Actel Designer) and verify I/O bank voltage compatibility, since the -1 speed grade and industrial temperature suffix define timing and environmental limits that cannot be changed after programming. This page adds value beyond the manufacturer datasheet by consolidating distributor availability, drop-in family alternates, comparison tables, and practical design notes in one place.
A54SX72A-1FGG484M - SX-A FPGA 108K Gates 484-BGA | Microchip

A field programmable gate array (FPGA) is a semiconductor device containing a matrix of configurable logic blocks (CLBs) interconnected by programmable fabric, allowing designers to implement custom digital logic without fabricating an ASIC. The SX-A family is a one-time-programmable antifuse FPGA line, positioned within the broader programmable logic hierarchy: FPGA -> programmable logic device -> digital IC -> semiconductor. Antifuse technology means the configuration is permanently set at programming time, giving non-volatile, highly secure, radiation-tolerant behavior with no configuration PROM required at power-up. Key differentiating features include the A54SX72A die fabricated on a 0.25 um CMOS process, a 2.5 V core supply, 6036 CLBs (4024 logic cells per distributor parametric listings), and a -1 speed grade supporting up to 250 MHz clock rates. Quadrant clock inputs (A, B, C, D pins) support low-skew global clocking across four die quadrants, per the SX-A family datasheet. Architecturally, the SX-A fabric combines C-cells for combinational logic and R-cells for registers, with dedicated routing segments that provide predictable, near-ASIC timing. Because the antifuse interconnect is permanent, designs benefit from low static power, no configuration bitstream exposure, and inherent resistance to configuration bit-flip issues compared to SRAM FPGAs. Typical applications include industrial control, communications bridging, aerospace and defense glue logic, secure single-chip logic integration, and legacy system continuity where SRAM-based programmability is not required. When designing, verify I/O bank voltage compatibility with the 2.5 V family supply rules and account for the one-time-programmable nature by completing simulation and timing closure before programming.
