A54SX72A-1PQ208I - 108K-Gate Antifuse FPGA, 2.5V | Microchip
The Microchip Technology (formerly Microsemi/Actel) A54SX72A-1PQ208I is a 108,000-system-gate antifuse FPGA from the SX-A family with 171 user I/O pins, up to 250 MHz system performance, and a 2.5V core supply, housed in a 208-pin PQFP (208-BFQFP) surface-mount package with industrial temperature rating. A field-programmable gate array (FPGA) is a semiconductor device containing a fabric of configurable logic blocks (CLBs) and interconnects that the designer programs to implement custom digital logic. Within the programmable logic hierarchy, the SX-A sits in the antifuse FPGA class: its interconnect is permanently programmed at power-up by blowing antifuse links, which makes the configuration non-volatile, instantaneous (no configuration PROM or boot time), and highly resistant to bit-stream readback - a key security and reliability advantage over SRAM FPGAs. Key features of the A54SX72A include 6,036 logic array blocks (LABs/cells), 0.25 um CMOS process technology, quadrant clock networks (CLKA, CLKB, and QCLK) for low-skew global clocking, and user-programmable I/O supporting up to 360 pins across the family (171 on this package). The -1 speed grade balances cost and performance for designs clocked up to 250 MHz. The architecture uses a sea-of-modules structure with dedicated flip-flops (up to 2,012 across family variants) and efficient routing, delivering ASIC-like performance in a one-time-programmable device. Because the antifuse fabric is non-volatile, no configuration controller is required, reducing bill-of-materials cost and board complexity. Typical applications include industrial control and automation, communications and networking line cards, aerospace and defense systems (in radiation-tolerant sibling families), and bridge logic or glueless interface integration where a single low-cost, secure, low-power device replaces multiple ASSPs and discrete logic. Design consideration: as a one-time-programmable antifuse device, the design must be fully verified in simulation before programming - there is no in-system reprogramming, so budget for engineering samples and programming socket costs.

A54SX72A-1PQG208I - 108K Gate FPGA 208-PQFP | Microchip
The Microchip Technology A54SX72A-1PQG208I is an SX-A family antifuse FPGA offering 108,000 system gates, 171 user I/O, and 250 MHz system performance, housed in a 208-pin PQFP (BFQFP) package with industrial temperature rating. Originally developed by Actel and later Microsemi, this one-time-programmable FPGA fabricates on a 0.25 um CMOS process operating from a 2.25 V to 5.25 V supply range. An FPGA (Field-Programmable Gate Array) is a semiconductor device containing configurable logic blocks (CLBs) and programmable interconnects that designers configure in the field to implement custom digital circuits. Within the programmable logic hierarchy, the SX-A family belongs to the antifuse FPGA category, sitting alongside SRAM-based and flash-based FPGAs as a third programmable logic architecture. Antifuse devices retain their configuration permanently after one-time programming, giving them inherent radiation tolerance, low static power, and instant-on behavior without external configuration memory. Key features of the A54SX72A-1PQG208I include 6,036 logic array blocks (LABs), a dedicated clock quadrant structure with four quadrant clock inputs for low-skew clock distribution, and 171 user I/O supporting 3.3 V and 5 V compatible signaling. The -1 speed grade supports internal toggle rates up to 250 MHz, adequate for telecommunications framing, glue logic consolidation, and bus-interface functions. Architecturally, the SX-A family uses a sea-of-modules routing fabric with antifuse interconnect elements that are programmed once using Actel/Microchip programming hardware. Because there is no configuration bitstream stored externally, the device powers up functionally within microseconds and presents no configuration-bitstream security exposure, a classic advantage in defense and industrial designs. Typical applications include industrial automation control, telecommunications and data-communications interface boards, bridge logic between legacy buses and modern controllers, and obsolescence-mitigation retrofits in long-lifecycle military and avionic systems where deterministic instant-on startup is mandatory. A critical design consideration is that antifuse FPGAs are one-time-programmable: any logic change requires a new physical device, so thorough simulation before programming is essential. The 208-PQFP also demands careful power-plane decoupling at 2.5 V core and I/O supplies. This page synthesizes distributor pricing, drop-in same-package alternatives, comparison data, and practical design notes not found in the manufacturer datasheet, providing engineering decision support beyond the standard product listing.

Fabricated on 0.25 um / 0.22 um CMOS technology and powered from a 2.5 V core, it supports system clock frequencies up to 250 MHz for high-performance glueless logic integration. An antifuse FPGA is a field-programmable gate array whose interconnect is permanently programmed at power-up programming time by blowing antifuse elements, in contrast to SRAM-based FPGAs that reload configuration from an external memory at every power cycle. Within the programmable logic hierarchy, the A54SX72A sits at the top of the SX-A family (above the SX08, SX16 and SX32 members), providing a non-volatile, single-chip solution that requires no configuration PROM, reducing bill-of-materials cost and improving design security because the bitstream cannot be read back. Key features include 6,036 configurable logic blocks (CLBs), 171 user-programmable I/Os compatible with TTL, LVTTL, LVCMOS2, 3.3 V PCI and 5.0 V PCI signaling standards, four quadrant clock inputs (CLKA-CLKD) feeding dedicated global clock networks, and combinatorial logic delays low enough for 250 MHz system operation at the faster speed grades. The -1 speed grade offers a cost-optimized timing point within the same die and package. The architecture uses a sea-of-modules fabric with dedicated carry logic and embedded clock distribution, enabling designers to integrate multiple glue-logic, state-machine and bus-interface functions into one low-power device. Because programming is one-time (OTP), the part is well suited to long-lifecycle industrial, communications, avionics-adjacent and defense-related platforms where configuration volatility is unacceptable. Typical applications include protocol bridging and bus interface conversion in industrial automation, backplane control logic in networking and telecommunications equipment, and secure single-chip logic integration in systems requiring deterministic power-up behavior without external boot memory. Design consideration: antifuse FPGAs are one-time programmable - reserve spare I/O and logic headroom, and lock the netlist before production programming, since design changes require new devices. This page adds distributor pricing tiers, drop-in alternatives within the same 208-PQFP footprint, and practical design notes synthesized beyond the manufacturer datasheet.

An antifuse FPGA is a one-time-programmable (OTP) programmable logic device in which permanent interconnects are formed at programming time. Unlike SRAM-based FPGAs, antifuse devices are non-volatile, require no configuration PROM, offer inherent resistance to bit-stream readback attacks, and exhibit low static power. Within the programmable logic hierarchy, the A54SX72A belongs to the SX-A family -> antifuse FPGA -> field programmable gate array -> programmable logic IC. Key features include single-chip integration (no external boot device), support for 2.5V, 3.3V, and 5V I/O standards on a 2.5V core, and fabrication on 0.22/0.25 um CMOS antifuse technology. The -2 speed grade balances performance and cost, and the 256-FBGA (17 mm x 17 mm, 1.0 mm ball pitch per distributor listings for the package family) saves board area versus the PQ208 alternatives. The SX-A architecture uses a sea-of-modules fabric with fast carry logic and dedicated flip-flops per cell, enabling pipelined datapaths and state machines at clock rates approaching the datasheet 294 MHz toggle figure. Programming is performed via Microchip (Actel) Silicon Sculptor hardware after board assembly, which makes the device well suited to fixed-configuration, cost-sensitive production designs. Typical applications include industrial control, glue logic integration, bus interface bridging, communications equipment, and military/aerospace systems that value the radiation-tolerant heritage and non-volatile security of antifuse technology. Design consideration: because the device is one-time programmable, freeze the netlist and verify timing in simulation before committing silicon; budget for rework if late design changes are likely.

A54SX72A-2FG256I - SX-A Antifuse FPGA 108K Gates | Microchip
The Microchip Technology (formerly Actel/Microsemi) A54SX72A-2FG256I is an SX-A family antifuse FPGA with 108K system gates (72K typical usable gates, 4024 logic modules), 203 user I/Os, and a 256-ball Fine-Pitch Ball Grid Array (FBGA, 17x17 mm) package in industrial temperature grade (-40C to +85C). An antifuse FPGA is a one-time-programmable (OTP) programmable logic device in which configurable interconnect elements are permanently formed at programming time. In the programmable logic hierarchy, the A54SX72A sits alongside FPGA and CPLD families as a field-programmable gate array; unlike SRAM FPGAs it requires no configuration boot memory, offering instant-on operation, inherent design security against bitstream readback, and very low static power, making it a power-management-friendly alternative to SRAM-based devices. Key features include a sea-of-modules CMOS architecture fabricated on a 0.25 um/0.22 um process, a core supply of 2.5V, and system-level toggle performance up to approximately 294 MHz. The device provides three dedicated clock networks (CLKA, CLKB, and quadrant clock QCLK), giving flexible global and regional clocking for high-performance sequential designs. The industrial I suffix qualifies the device for -40C to +85C operation. Technical depth: the SX-A family uses a fine-grained sea-of-modules architecture with combinational and sequential modules, enabling high logic utilization. Because configuration is stored in antifuse interconnect rather than external flash, the device is immediately active at power-up with no configuration time and no external configuration PROM, reducing board BOM and improving system reliability in hostile environments. Typical applications include industrial automation and control, communications and networking line cards, avionics and military glueless logic integration, and test equipment, where the device integrates multiple discrete logic functions into a single low-cost, secure, low-power chip. Design consideration: because the device is one-time programmable, verify the design fully in simulation (Libero SoC design flow) before programming; spare I/O and margin in module utilization are recommended for late design changes.

An antifuse FPGA is a one-time-programmable (OTP) programmable logic device whose interconnect switches are permanently formed at programming time. Within the programmable logic hierarchy (FPGA -> field programmable gate array -> programmable logic device -> semiconductor), antifuse FPGAs occupy the non-volatile, high-security niche: unlike SRAM FPGAs they need no configuration ROM, power up instantly with no configuration time, and their bitstream cannot be read back, making them a staple in military, aerospace, and industrial designs where IP protection matters. Key features include 0.25 um/0.22 um CMOS antifuse technology, 2.25V to 2.75V core supply with mixed 3.3V/2.5V/1.5V-capable I/O banks, 360 available I/Os in the FBGA-484 package, and registered per-module performance up to 294 MHz. The SX-A architecture uses a sea-of-modules fabric with C-cells (combinational) and R-cells (sequential), each driving local and long-line routing for predictable, ASIC-like timing. The SX-A family provides a low-cost single-chip integration path that replaces multi-chip glue-logic with one time-safe, secure, low-power device. Design entry uses Libero SoC / Designer software with VHDL or Verilog, and timing is verified post-layout, not estimated. Typical applications include bridge logic and bus interface integration in industrial equipment, secure control planes in defense and avionics systems, and glueless processor/peripheral interfacing where instant-on and configuration-readback protection are required. Design consideration: the device is one-time programmable and RoHS non-compliant in this commercial speed grade; verify temperature range (0C to +70C) and soldering process compatibility before commit. For lead-free assembly choose the -2FGG484 green variant with identical footprint.

The Microchip (Actel/Microsemi) A54SX72A-2FG484I is a 108,000-system-gate antifuse FPGA from the SX-A family with 6,036 logic cells, 360 user I/Os, and a 294 MHz toggle capability, fabricated on 0.25 um/0.22 um CMOS antifuse technology and housed in a 484-ball fine-pitch FBGA package rated for the industrial temperature range. An antifuse FPGA is a type of field-programmable gate array in which the interconnect configuration is permanently set at programming time by rupturing antifuse elements. Unlike SRAM-based FPGAs, antifuse devices are nonvolatile, require no external configuration ROM, and power up instantly with a fully determined routing fabric - placing them in the programmable logic hierarchy between one-time-programmable SPLDs and reconfigurable SRAM FPGAs. Key features include single-chip integration of multiple logic functions, support for 2.5 V, 3.3 V, and 5 V I/O standards on a 2.5 V core, low dynamic power consumption typical of antifuse fabrics, and deterministic timing with no configuration readback vulnerability - an inherent security advantage over SRAM FPGAs. The device provides global and quadrant clock networks (CLKA, CLKB, and QCLK) for flexible clock distribution. The SX-A architecture is built around a sea-of-modules fabric of combinational and sequential logic modules interconnected by a fine-grained antifuse routing matrix. The 0.22 um/0.25 um CMOS process yields high gate utilization with predictable interconnect delays. Because configuration is stored physically in the antifuse elements, there is no bitstream to intercept or corrupt, making the family attractive for military, avionics, and industrial designs requiring configuration immutability. Typical applications include glueless bus bridging, industrial control, communications line-card logic, avionics and defense systems requiring one-time-programmable security, and legacy system obsolescence redesigns where a deterministic, nonvolatile FPGA is mandated. When designing with this device, remember the antifuse is one-time programmable: verify the design thoroughly in simulation and with a prototype device before production programming. Plan I/O bank voltage assignments early since 2.5 V, 3.3 V, and 5 V I/O mixing constrains ball assignment.

An antifuse FPGA is a one-time-programmable (OTP) programmable logic device whose interconnect switches are permanently formed at programming time. Unlike SRAM-based FPGAs, antifuse devices retain their configuration through power cycles without an external configuration flash, offer inherent resistance to bit-stream copying, and exhibit lower static power and better SEU immunity. Within the programmable logic hierarchy, the SX-A family sits among Actel-origin (now Microchip/Microsemi) antifuse FPGAs, positioned as a low-cost, high-performance, single-chip integration solution. Key features of the A54SX72A-2FGG256 include the largest gate count in the SX-A family (108K system gates), a sea-of-modules architecture built on a 0.25 um CMOS process operating from a 2.5V core supply, and speed grade -2 performance supporting clocks up to 313 MHz. The FGG256 package provides 203 usable user I/O on a 1.0 mm ball pitch, supporting fine-pitch surface-mount assembly. Technically, the device uses multiplexer-based combinational modules and register modules arranged in a sea-of-modules fabric, with dedicated global and quadrant clock networks (CLKA, CLKB, and QCLK) for low-skew clock distribution. Routing is performed through one-time-programmable antifuse elements, giving deterministic, configuration-free power-up behavior and strong design security since the programmed netlist cannot be read back. Typical applications include industrial control, telecommunications and networking line cards, aerospace/defense logic consolidation, medical equipment glueless interface bridging, and legacy system life-cycle extension where SRAM FPGA configuration overhead or security concerns make OTP antifuse logic preferable. Design consideration: because the device is one-time-programmable, verify the complete design in simulation and, where available, in a larger-package prototype before committing the antifuse programming step; programming errors are not recoverable.

A54SX72A-2FGG256I - 108K-Gate Antifuse FPGA 256-BGA | Microchip
The Microchip Technology (Microsemi/Actel) A54SX72A-2FGG256I is a high-density antifuse FPGA from the SX-A family delivering 108,000 typical system gates (72,000 nominal gates, 4,024 logic cells) with toggle rates up to 294 MHz, housed in a 256-ball Fine-Pitch Ball Grid Array (FBGA, 17x17 mm) package with 203 user I/Os and industrial temperature rating (-40C to +85C). An antifuse FPGA is a type of field-programmable gate array whose interconnect elements are permanently programmed at power-up programming time using a one-time programmable (OTP) antifuse technology. Unlike SRAM FPGAs, antifuse devices retain their configuration without any boot device, offer inherent resistance to configuration readback (a security advantage), and exhibit low static power, making them a foundational category within the programmable logic hierarchy: FPGA -> one-time-programmable FPGA -> antifuse FPGA -> programmable logic device. Key features include 0.25 um CMOS antifuse process technology, single 2.5V core supply operation for low power, dedicated quadrant and global clock networks (CLKA, CLKB and QCLK) supporting high-speed synchronous design, and a sea-of-modules architecture built on C-cells and R-cells that maximizes routable logic density. The -2 speed grade is the fastest commercial bin in the SX-A family, supporting core toggle frequencies up to 294 MHz. Technically, the SX-A architecture combines high-performance routing with predictability: each logic module drives short local and long-line routing segments, and the antifuse interconnect adds negligible capacitance, preserving speed. Because configuration is non-volatile and loaded internally, the device requires no external PROM, reduces board BOM cost, and eliminates configuration-bitstream loading latency at power-up. Typical applications include industrial control and automation glue logic integration, communications and networking line-card functions, aerospace and defense program-protected logic (secure by readback prevention), and single-chip consolidation of multiple ASSP/PLD functions to cut system cost. Design consideration: antifuse devices are one-time programmable, so fully verify your design in simulation and, where possible, prototype on the companion SX-A development flow before committing production programming files.

A54SX72A-2FGG484 - 108K Gate SX-A FPGA 484-BGA | Microchip
The Microchip Technology A54SX72A-2FGG484 is an antifuse FPGA from the SX-A family delivering 108,000 system gates (72,000 typical gates, 6,036 CLBs) with 360 user I/Os and a maximum toggle frequency of 294 MHz, housed in a 484-ball FBGA (FGG484) package operating from a 2.5 V core supply. An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a matrix of configurable logic blocks (CLBs) interconnected by programmable fabric, allowing designers to implement custom digital circuits after manufacturing. Within the programmable logic hierarchy, the SX-A sits in the antifuse FPGA class: its program connections are one-time programmable, which yields lower cost, higher security against bitstream readback, and lower static power than SRAM-based FPGAs. Key features include 0.25 um CMOS antifuse technology, 2.5 V single-supply operation, up to 360 user-accessible I/Os in the 484-ball package, and a 1 mm ball pitch that simplifies PCB layout. The -2 speed grade supports the fastest timing within the SX-A family, making it appropriate for state machines, glue logic consolidation, bus interfacing, and control-plane functions at moderately high clock rates. Technically, the SX-A architecture combines C-cell modules for combinational logic with R-cell register modules for sequential elements, providing predictable single-module routing delays. Because the antifuse fabric is programmed once at the board factory (via a programmer such as Silicon Sculptor), no configuration PROM is needed at power-up, and the design is effectively immune to bitstream cloning. Typical applications include industrial automation control boards, communications line cards, test and measurement backplanes, and defense/aerospace systems where the one-time-programmable, low-power antifuse fabric and long product lifecycle are valued. Design consideration: because antifuse FPGAs cannot be reprogrammed after programming, verify the design completely in simulation and, if possible, prototype on a reprogrammable platform before committing; also reserve spare I/O bank headroom for ECO changes.

An antifuse FPGA is a field-programmable gate array whose interconnect programming elements are one-time-programmable antifuse cells rather than SRAM configuration memory. In the programmable-logic hierarchy (antifuse FPGA -> FPGA -> programmable logic device -> logic IC -> semiconductor), this gives the device inherent non-volatility, no external configuration PROM, instant-on behavior, and high resistance to configuration upset - key reasons antifuse FPGAs remain popular in military, aerospace, and industrial systems. Key features of the -2FGG484I speed grade 2 device include the largest member of the SX-A family at 72K gates, 360 maximum user I/O, a 2.5V core supply (with supply range cited from 2.25V to 5.25V on I/O domains per distributor data), 0.25 um process technology, and industrial operating temperature range of -40C to +85C (TA). The G suffix in FGG484 denotes lead-free / RoHS-compliant ball metallization. Architecturally, the SX-A family uses a sea-of-modules fabric with combinational and sequential logic modules, plus clock resources including CLKA, CLKB, and quadrant clock (QCLK) networks in the A54SX72A, enabling efficient global and regional clocking for synchronous designs. Because the programming layer is antifuse, designers get the timing determinism and security benefits of a fixed interconnect after programming. Typical applications include glueless bus interface and bridge logic, industrial automation controllers, communications line cards, and defense/aerospace electronics where instant-on, configuration-security, and low single-chip system cost matter. Design consideration: as a one-time-programmable device, the bitstream cannot be reloaded in-system - verify your design fully in simulation and use Microchip/LibreOffice-compatible Designer software timing sign-off before programming production units.

A54SX72A-2PQ208 - 108K-Gate Antifuse FPGA 208-PQFP | Microchip
The Microchip Technology (Microsemi/Actel) A54SX72A-2PQ208 is a 108,000-gate antifuse FPGA from the SX-A family, delivering 4024 logic cells, up to 2012 dedicated flip-flops, and 171 user I/O pins in a 208-pin BFQFP (PQFP) surface-mount package. It operates from a 2.5V supply and supports toggle rates up to 294 MHz on 0.25 um CMOS process technology. An antifuse FPGA is a type of field-programmable gate array whose interconnects are permanently programmed at power-up by blowing microscopic antifuse elements. Unlike SRAM-based FPGAs, antifuse devices are non-volatile, require no configuration ROM, boot instantly, and are inherently resistant to bit-stream readback, which makes them a class of programmable logic within the broader power/logic semiconductor hierarchy favored for high-reliability and secure designs. Key features include 108,000 available system gates, 171 user-programmable I/O pins in this package (up to 360 across the family), a proprietary 0.25 micron CMOS process, and instant-on non-volatile configuration. The '-2' speed grade offers the standard commercial performance point of the SX-A family, balancing logic density, I/O count, and cost for single-chip integration of glue logic, bus interfaces, and control functions. The SX-A architecture uses a sea-of-modules fabric with C-cell (combinational) and R-cell (sequential) logic modules, plus dedicated decoders and quadrant/global clock networks (CLKA, CLKB, QCLK) that support multiple clock domains with low skew. Actel (now Microchip) designed the family for low power and high security, with no configuration memory contents exposed externally. Typical applications include industrial control systems, military and aerospace logic integration, telecommunications line-card control, bus bridging, and secure single-chip consolidation of multiple discrete logic devices. When designing with this device, verify I/O banking voltage compatibility with adjacent logic families and allocate proper power/ground pin pairs; antifuse programming is one-time, so design margins and timing closure in Libero SoC should be confirmed before release.

A54SX72A-2PQ208I - 108K-Gate Antifuse FPGA, PQFP-208 | Microchip
The Microchip Technology (formerly Actel/Microsemi) A54SX72A-2PQ208I is a 108,000-system-gate antifuse FPGA from the SX-A family, offering 6036 logic modules, up to 2012 dedicated flip-flops, 171 user-programmable I/O pins, and up to 294 MHz system performance in a 208-pin PQFP (BFQFP, 28x28 mm) package, fabricated on a 0.25 um CMOS process and powered from a single 2.5V supply. An FPGA (field-programmable gate array) is a semiconductor device containing a fabric of configurable logic blocks and interconnects that the designer programs after manufacturing. The SX-A family uses Actel's proprietary antifuse technology: one-time programmable interconnect elements that permanently set the routing at power-on. Compared with SRAM-based FPGAs, antifuse devices need no configuration PROM, have no configuration-readback vulnerability, and provide inherently lower power and higher design security, placing them in the one-time-programmable programmable-logic hierarchy alongside PLDs and CPLDs. Key features include the largest density in the SX-A family at 108K system gates, the -2 speed grade supporting clock rates to 294 MHz, dual 2.5V-tolerant I/O banking with up to 360 user I/Os at family level (171 on the PQ208 package), and quadrant/global clock networks (CLKA, CLKB, and QCLK) for low-skew clock distribution across the die. The 0.25 um CMOS antifuse architecture delivers deterministic interconnect delays, making timing closure more predictable than in SRAM FPGAs. Because configuration is stored in the silicon itself, the device is immediately active at power-up with zero configuration time, a significant advantage in systems with strict boot-latency requirements, and the lack of a bitstream dramatically reduces the risk of design cloning. Typical applications include telecommunications and networking line cards, industrial automation controllers, avionics and space-adjacent control logic, glueless bridge logic between processors and peripherals, and legacy system life-cycle maintenance where the A54SX72A was designed in originally. A key design consideration: antifuse FPGAs are one-time programmable, so design verification must be completed fully before programming production units; use the Libero SoC design suite and microsemi programming hardware, and budget for a small amount of spare logic capacity in the 108K-gate budget. This page adds value beyond the datasheet by synthesizing distributor pricing, drop-in same-package alternatives, and practical design notes for obsolescence-risk planning on the SX-A platform.

The SX-A family uses antifuse programming technology: one-time programmable (OTP) connections that are permanently set at programming time. Within the programmable logic hierarchy, the A54SX72A sits at the top of the SX-A density range, above the A54SX32A and A54SX16A, providing single-chip integration of glue logic, bus interfaces, and state machines. Key features include 108K system gates in a low-cost single-chip solution, a maximum toggle rate of 294 MHz enabled by the -2 speed grade, 0.25 um CMOS process technology, and low power consumption typical of antifuse architectures. Because antifuse interconnects are non-volatile and inherently resist reading back the design, the device provides strong design security and requires no configuration boot time or external configuration memory. The 2.5 V core supply and 171 user I/O pins support board-level bus interfacing at industrial voltages. Quadrant clock networks (CLKA, CLKB, and QCLK resources) distribute low-skew clocks across the die, as documented in Microchip's SX-A family datasheet and the A54SX72A quadrant clocks application note. Typical applications include industrial automation controllers, aerospace and defense logic integration, telecommunications line-card glue logic, and legacy system redesigns that consolidate multiple ASSP/PLD functions into one OTP device. Design consideration: antifuse FPGAs are one-time programmable - verify the design fully in simulation before programming, since no field rework is possible.

The Microchip Technology A54SX72A-2PQG208I is a 108K-system-gate antifuse FPGA from the SX-A family, offering 171 user I/O and a speed grade -2 performance rating, housed in a 208-pin Fine-Pitch Quad Flat Package (PQFP/BFQFP) with industrial temperature rating (-40C to +85C). An antifuse FPGA is a type of field-programmable gate array whose interconnects are permanently programmed at power-up by blowing antifuse links. Unlike SRAM-based FPGAs, antifuse devices are non-volatile and one-time programmable, which means no configuration PROM is required, configuration time is eliminated, and the bitstream is physically invisible to reverse engineering - a built-in security advantage. Key features include 108K system gates of reprogrammable-at-design-time Sea-of-Modules architecture, 171 available user I/O, support for clock speeds up to 217 MHz, and low static power consumption typical of the SX-A family. Input levels are compatible with standard TTL, LVTTL, LVCMOS2, 3.3 V PCI, and 5 V PCI specifications per the SX-A family datasheet. Architecturally, the SX72A die arranges combinational and sequential modules in a Sea-of-Modules fabric with dedicated global and quadrant clock networks (CLKA/CLKB plus four quadrant clock inputs) for low-skew distribution, enabling high-speed state machines and datapath designs. Typical applications include industrial control, communications and networking equipment, avionics and mil-aerospace glue logic, and ASIC prototype or single-chip integration where the board must boot instantly with a secure, non-readable configuration. Design consideration: antifuse devices are one-time programmable - a design change requires a new device, so full simulation and timing closure in Libero/Microchip design tools are mandatory before programming.

The combination of deterministic interconnect delay, low power, and single-chip integration makes SX-A attractive where SRAM configuration overhead is undesirable. Architecturally, the A54SX72A uses Actel's metal-to-metal antifuse switching element in a sea-of-modules fabric. Routing delay is largely independent of fanout, giving designers predictable timing. According to the SX-A family datasheet, designers using quadrant clocks in the A54SX72A should refer to Microchip's quadrant clock application notes for CLKA, CLKB, and QCLK macro usage. Typical applications include aerospace and defense subsystem prototyping (the RTSX-SU CQ208 device is pin-compatible with SX-A in CQ208 for drop-in migration from commercial prototyping to radiation-tolerant production), industrial control, communications line cards, and test equipment glue logic consolidation, where multiple discrete functions are integrated into a low-cost single-chip solution. A key design consideration is that the A54SX72A is one-time programmable: verify the design thoroughly in simulation and, where possible, prototype on in-system-programmable devices before committing. Also note the ceramic CQFP contains lead and is RoHS non-compliant, restricting use to exemptions such as military/aerospace systems.

The FF speed grade designation defines the standard timing grade, while the fine-pitch BGA enables dense, high-I/O board layouts for backplane and mezzanine cards. Technically, the SX-A fabric uses asea-of-modules architecture with C-cells for combinatorial logic and R-cells for sequential logic, routed through a segmented antifuse interconnect. Because the antifuse programming is permanent, designs are immune to configuration readback attacks and do not require configuration PROMs, reducing bill-of-material cost and improving power-up reliability in industrial systems. Typical applications include industrial automation control, telecommunications line cards, test and measurement instrumentation, and military/aerospace legacy systems requiring secure one-time-programmable logic at moderate clock rates. Design considerations: because the device is one-time programmable, timing closure and pin assignment must be finalized before programming; use the Libero SoC design suite for compilation and verify worst-case timing at the 2.25V supply corner. Note the 0C to +70C commercial temperature range when selecting this grade.
