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.

A54SX72A-2FGG484I - SX-A FPGA 72K Gates 484-FBGA | Microchip
The Microchip Technology (Microsemi/Actel) A54SX72A-2FGG484I is an antifuse FPGA from the SX-A family delivering 72,000 system gates, 4,024 logic cells (modules), up to 360 user I/Os, and system performance up to 294 MHz, housed in a 484-ball Fine-Pitch Ball Grid Array (FBGA/FPBGA, 27 x 27 mm, 1.0 mm ball pitch). 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.
A54SX72A-2PQG208 - 108K Gate Antifuse FPGA | Microchip
The Microchip Technology (formerly Microsemi/Actel) A54SX72A-2PQG208 is an SX-A family antifuse FPGA with 108,000 system gates (72,000 typical gates), 4,024 logic cells, 171 user I/O pins, and a -2 speed grade, housed in a 208-pin plastic quad flat pack (PQFP/BFQFP, 28 mm x 28 mm, 0.5 mm pitch). A field programmable gate array (FPGA) is an integrated circuit that implements user-defined digital logic through a programmable interconnect fabric. 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.

A54SX72A-2PQG208I - 108K-Gate Antifuse FPGA, 171 I/O | Microchip
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.

A54SX72A-CQ208 - 108K-Gate Antifuse FPGA, 2.5V | Microchip
The Microchip (Microsemi/Actel) A54SX72A-CQ208 is an SX-A family antifuse FPGA offering up to 108,000 system gates, 171 user-programmable I/O pins, and a 217 MHz system performance ceiling, packaged in a 208-pin ceramic CQFP (BFCQFP with tie bar) operating at a 2.5V core supply. An antifuse FPGA is a field-programmable gate array whose interconnect elements are permanently programmed at power-up via antifuse links. Unlike SRAM-based FPGAs, antifuse devices retain their configuration without any external boot memory, provide inherent resistance to configuration readback attacks, and exhibit low static power. Within the programmable-logic hierarchy, the SX-A family sits in the one-time-programmable (OTP) FPGA class, positioned above simple PLDs/CPLDs and below flash-based SoC FPGAs. Key features include a 0.25 um CMOS process technology, up to 2,012 dedicated flip-flops, 4,024 program modules (combinatorial and sequential cells), quadrant and global clock networks (CLKA, CLKB, and QCLK resources) supporting high-speed synchronous designs, and a ceramic package suited to demanding environments. 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.

Operating from a single 2.5V supply (2.25V to 2.75V), it is built on a 0.25 um CMOS process. An antifuse FPGA is a one-time-programmable (OTP) programmable logic device in the broader hierarchy: FPGA -> programmable logic device -> digital IC -> semiconductor. Unlike SRAM-based FPGAs, the SX-A family programs via proprietary antifuse interconnect elements, so the configuration is fixed at programming time and retained without any external configuration memory, boot PROM, or configuration controller. Key differentiating features include the 108K-gate capacity of the largest SX-A member, up to 2,012 dedicated flip-flops with 4,024 registers total, 217 MHz toggle performance, and single-chip integration that removes the cost and reliability burden of external configuration devices. The ceramic CQFP with tie bar package provides the mechanical robustness and hermeticity required in high-reliability (HiRel) systems, and the -55C to +125C operating range suits military and aerospace environments. Architecturally, the SX-A device uses a sea-of-modules structure with combinational and sequential logic modules interconnected through low-resistance antifuse links. Clocking resources include CLKA, CLKB, and quadrant clock (QCLK) networks, described in the Microchip SX-A Family FPGAs datasheet (sxa_ds.pdf) and the Using A54SX72A and RT54SX72S Quadrant Clocks application note, enabling low-skid global and regional clock distribution. Typical applications include satellite and space-adjacent electronics, military avionics, glue-logic integration and bus interface in defense systems, industrial high-reliability controllers, and legacy design sustainment where an OTP, radiation-tolerant-family-derived FPGA is preferred. Designers value the single-chip solution for reducing board area and eliminating configuration-flash security concerns. Design consideration: the antifuse fabric is one-time programmable - verify timing closure and functional simulation in Libero SoC before programming, and budget I/O count carefully since 171 I/Os are available on this CQFP-208 variant versus up to 360 on other packages.

An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a fabric of programmable logic blocks and interconnects that the designer configures after manufacturing. Within the programmable logic hierarchy, the SX-A sits in the antifuse FPGA category: one-time programmable (OTP) devices whose interconnect is permanently set at programming time, in contrast to SRAM-based FPGAs from the volatile-configuration branch of power management of system digital logic. Key differentiating features include the antifuse interconnect, which provides non-volatile, configuration-readback-free operation with inherent design security and no external configuration PROM requirement; support for TTL, LVTTL, LVCMOS2, 3.3 V PCI, and 5 V PCI input standards; quadrant clock inputs (CLKA-CLKD) feeding global clock distribution networks; and low static power typical of antifuse technology. Architecturally, the SX-A fabric combines combinational and sequential modules, dedicated flip-flops, and wide-decode resources, enabling glue logic consolidation, bus interfacing, and state-machine integration into a single chip. The ceramic CQFP package with tie bar supports surface-mount assembly and delivers superior thermal and reliability characteristics compared with plastic packages, making it suited to demanding environments. Typical applications include industrial control and automation, communications and networking backplanes, aerospace and defense prototyping systems, medical instrumentation, and test equipment, where single-chip integration of legacy ASIC or multiple-CPLD functions reduces board cost and power. Design consideration: antifuse FPGAs are one-time programmable, so functional verification must be complete before programming; use Actel/Microchip Libero or Designer software flows and reserve I/O and quadrant clocks per the SX-A datasheet guidelines.

It operates at a 2.5V core supply on a 0.25um/0.22um CMOS process with toggle rates up to 217-250 MHz. An antifuse FPGA is a one-time-programmable (OTP) programmable logic device whose interconnect switches are permanently formed at programming time. Unlike SRAM FPGAs, antifuse devices retain their configuration through power cycles without any external configuration ROM, offer intrinsic resistance to bitstream readback attacks, and exhibit very low static power - placing them in the programmable logic hierarchy below modern SRAM-based FPGA families but above ASICs for low-to-medium volume designs. Key features include 72K gates of registered programmable logic, high-speed flip-flops with clock rates in excess of 200 MHz, dedicated global and quadrant clock networks (CLKA, CLKB, and QCLK) for low-skew clocking, and the military-grade ceramic CQFP package with tie bar for reliable solder mounting and hermetic sealing. The 0.25um CMOS antifuse technology delivers deterministic timing, making the device well suited to glue logic consolidation and state-machine heavy designs. The SX-A architecture uses a Sea-of-Modules fabric composed of combinatorial and sequential modules organized into clusters and quadrants. Interconnect is formed by one-time programmable antifuse elements, giving fixed, timing-verified routing after programming. Design entry is via Libero SoC (formerly Actel Designer), with VHDL/Verilog synthesis and static timing analysis. Typical applications include military and aerospace embedded controllers, industrial automation glue logic, communications interface bridging, and obsolescence-mitigation redesigns where OTP security and instant-on configuration are required. Design consideration: because the device is one-time-programmable, verify the complete design with simulation and a target-board prototype before programming production units; antifuse programming is irreversible. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
A54SX72A-CQ256M - 108K Gate Antifuse FPGA, 256-CQFP | Microchip
The Microchip Technology A54SX72A-CQ256M is an antifuse FPGA from the SX-A family delivering 108,000 system gates, 213 user I/O, and a 256-ball BFCQFP with tie bar (256-CQFP, 75x75 mm) package, fabricated on a 0.25 um process and operating from a 2.5 V core supply. The M suffix denotes the extended (military) temperature operating grade. An antifuse FPGA is a one-time-programmable (OTP) programmable logic device in the broader FPGA hierarchy: FPGA -> field-programmable gate array -> programmable logic IC -> semiconductor. Unlike SRAM-based FPGAs, Actel (now Microchip) antifuse devices are non-volatile as-programmed, require no configuration PROM, are highly resistant to configuration upset, and offer inherently low power consumption at high gate counts. Key features of the A54SX72A include dedicated bidirectional clock buffers (CLKA, CLKB and QCLK circuits, unique to the A54SX72A within the family), up to 4,024 logic cells, and maximum toggle performance in the 217-250 MHz range per family datasheet data. The ceramic CQFP package with tie bar supports socketing and high-reliability surface-mount assembly, which is why the M-grade CQ256M variant is frequently used in defense, avionics, and space-adjacent programs requiring extended temperature range and ceramic packaging. Typical applications include military and aerospace glue logic integration, radiation-tolerant-adjacent industrial control, communications infrastructure, and obsolescence-driven redesigns where multiple discrete logic devices are consolidated into a single low-cost, low-power, secure one-time-programmable device. When designing with this device, note that antifuse programming is permanent - the completed design must be frozen before programming, and design changes require a new device. Verify I/O bank allocation and the 213 usable I/O against your pinout early, since CQFP packages cannot be re-routed after board layout.

A54SX72A-FFG256 - 108K-Gate SX-A FPGA, 256-BGA | Microchip
The Microchip Technology A54SX72A-FFG256 is a 108,000-system-gate SX-A family antifase-free CMOS Field Programmable Gate Array (FPGA) delivering 72,000 typical usable gates, 6,036 configurable logic blocks (CLBs), up to 203 user I/O pins, and a maximum clock frequency of 172 MHz in a 256-ball fine-pitch BGA (FBGA) package operating from a 2.5V supply. An FPGA (Field Programmable Gate Array) is a semiconductor device containing a fabric of programmable logic blocks and interconnects that designers configure in the field to implement custom digital circuits. Within the programmable logic hierarchy, the FPGA sits above CPLDs and below full ASIC/SoC solutions, offering ASIC-like integration without non-recurring engineering cost. The SX-A family from Microchip (originally Actel/Microsemi) is an antifuse-free one-time-programmable architecture known for nonvolatile configuration, instant-on operation, and strong resistance to configuration corruption - historically favored in military, aerospace, and industrial systems. Key features of the A54SX72A-FFG256 include the highest logic density in the SX-A family (108K system gates), 6,036 CLBs with a typical combinatorial delay of approximately 1.8 ns per CLB, and quadrant clock inputs (A/B/C/D) supporting four low-skew regional clock domains. The 256-ball FBGA packages the full I/O capability of the die in a compact 1.0 mm pitch footprint, and the 2.5V core supply keeps power consumption low for a device of this density. Architecturally, the SX-A fabric combines combinational logic modules and register modules with segmented routing resources. Being a CMOS 0.25 um/0.22 um generation device, it trades leading-edge process for proven reliability, radiation tolerance heritage, and long-life availability. Design entry is done with the Microchip (Microsemi) Libero SoC toolchain, which also supports the older Actel Designer flows. Typical applications include glueless system integration in aerospace and defense electronics, industrial control and automation, test and measurement instruments, and communications backplane logic where a single-chip, nonvolatile, instant-on programmable device replaces multiple ASSPs and MSI logic. A key design consideration: because SX-A devices are programmed once (nonvolatile), plan I/O banking and power sequencing carefully before programming, and verify quadrant clock assignments early in layout to avoid routing congestion on the 256-ball package.

A field programmable gate array (FPGA) is a semiconductor device containing a matrix of configurable logic blocks interconnected by programmable fabric, allowing designers to implement custom digital logic without fabricating an ASIC. The SX-A family uses Actel antifuse programmable-interconnect technology, which permanently programs connections at power-up configuration time - in contrast to SRAM FPGAs, the configuration is non-volatile, immune to configuration readback attacks, and requires no external configuration ROM. Key features include 2.25 V to 5.25 V supply operation, 0.25 um CMOS process technology, 0 C to +70 C commercial operating temperature range, and true single-chip integration that removes the need for boot PROMs. The antifuse fabric delivers deterministic interconnect delays, predictable timing, and low static power, while the 360 available I/O support mixed-voltage board environments common in industrial and aerospace logic designs. Architecturally, the SX-A array combines dedicated flip-flops, combinational modules, and embedded routing channels sized for high fan-out synthesis. Design entry and programming use the manufacturer's Libero SoC design suite with Synopsys or third-party synthesis flows targeting the Actel/Microsemi antifuse toolchain. Typical applications include glueless bus interfacing, industrial control logic, communication protocol bridging, military/aerospace secure logic (the antifuse fabric resists configuration readout), and ASIC prototyping where a one-time-programmable, radiation-tolerant-friendly fabric is preferred. Design consideration: because this is a one-time-programmable (OTP) antifuse device, verify the design fully in simulation and timing analysis before programming, and use the -FFG (commercial speed) grade only within the 0 C to +70 C range; the industrial -I grade is required for extended temperatures.

A54SX72A-FFGG256 - 108K Gate Antifuse FPGA, 256-BGA | Microchip
The Microchip Technology A54SX72A-FFGG256 is a 108,000-system-gate antifuse FPGA from the SX-A family, offering 72,000 typical usable gates, 6,036 configurable logic blocks (CLBs), and 203 user I/Os in a 256-ball Fine-Pitch BGA (FBGA-256) package. It operates from a nominal 2.5V supply (2.25V to 2.75V range) with a maximum clock frequency of up to 172 MHz and a typical combinatorial CLB delay of 1.8 ns. An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a fabric of configurable logic blocks and programmable interconnects that designers configure after manufacturing. Within the programmable logic hierarchy, the SX-A belongs to the antifuse FPGA category, sitting under the broader families of FPGAs, programmable logic devices (PLDs), and logic ICs. Unlike SRAM-based FPGAs, antifuse devices are one-time programmable, which provides inherent design security and non-volatile configuration without an external boot flash. Key features of the A54SX72A-FFGG256 include the 0.25 um CMOS process technology, low static power consumption typical of antifuse architecture, and the high-density 256-ball package that concentrates 203 user I/Os in a 17x17 mm-class footprint. 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.

An FPGA is a reconfigurable (or, in the antifuse case, one-time-programmable) logic device that sits within the broader semiconductor hierarchy of programmable logic ICs, below system-on-chip devices but far more flexible than fixed-function ASICs or PLDs. The SX-A family uses antifuse interconnect technology, which provides permanent, non-volatile routing after programming, eliminating configuration memory and giving inherent resistance to bit-stream readback attacks. Key features include 108,000 system gates, up to 360 I/O, a wide 2.25V to 5.25V supply range for the I/O structure, CMOS technology for low static power, and commercial-grade operation from 0C to +70C. One-time programmability means no configuration PROM is required on the board, reducing BOM cost and boot time to essentially zero. Technically, the SX-A architecture is based on the Actel (now Microchip) antifuse module structure with combinatorial and sequential modules, supporting system frequencies reported by distributors up to approximately 156-172 MHz depending on speed grade. Designs are compiled once; the antifuse programming is permanent, which suits long-lifecycle industrial and defense-oriented platforms. Typical applications include industrial control and automation, communications and networking line cards, aerospace and defense logic integration, and ASIC prototyping or bridge logic where single-chip integration replaces multiple glue-logic devices. Design consideration: because antifuse devices are one-time programmable, verify the netlist thoroughly in simulation before programming production units, and account for the 10-week manufacturer lead time when planning builds.

The one-time-programmable antifuse fabric gives inherent design security because the programmed bitstream is not stored in an externally readable configuration memory. Architecturally, the SX-A family uses a sea-of-modules structure with Combimodule (combinational + sequential) logic cells on a channeled routing fabric, balancing interconnect delay predictability with high logic density. The 217 MHz toggle capability suits timing-critical glue logic and datapath integration. Typical applications include military and aerospace systems, industrial automation controllers, communications backplanes, and automotive electronics where non-volatile, single-chip, instant-on programmable logic is required. The A-grade temperature variant supports -40C to +125C ambient operation.

The Microchip Technology (formerly Microsemi/Actel) A54SX72A-FG256I is an SX-A family antifuse field programmable gate array (FPGA) delivering 108K system gates (72K raw gates, 4024 module cells), 203 user I/O, and system performance up to 217 MHz in a 256-ball fine-pitch BGA (17x17 mm) package, rated for the industrial temperature range of -40C to +85C. An antifuse FPGA is a one-time-programmable (OTP) programmable logic device in which each programmable interconnect point is an open circuit until permanently programmed. Unlike SRAM-based FPGAs, antifuse devices retain their configuration through power cycles without any external configuration device, offer intrinsically higher design security because the bitstream cannot be read back, and add very little static power. The SX-A family sits within the broader hierarchy: FPGA -> antifuse FPGA -> programmable logic device -> semiconductor. Key differentiating features include 0.25 um CMOS antifuse technology, a wide 2.25V to 5.25V supply range supporting mixed 3.3V and 5V system environments, quadrant and global clock networks (CLKA, CLKB, QCLK) for low-skew timing, and single-chip integration that eliminates the external configuration PROM required by SRAM FPGAs. Architecturally, the A54SX72A is built from C-cells and S-cells organized into clusters, providing a register-rich structure well suited to state machines, glue logic consolidation, bus interfaces, and control-plane functions. The datasheet details quadrant clock usage in the A54SX72A via the Global Clock Networks application notes. Typical applications include industrial automation control, military and aerospace subsystems, telecommunications line cards, and legacy system life-cycle extensions where OTP security and instant-on behavior are required. Design consideration: the 256-FBGA requires careful ball-map planning for power and ground integrity; because the device is OTP, verify the bitstream thoroughly in simulation before programming.

A54SX72A-FG256M - 72K Gate Antifuse FPGA 256-BGA | Microchip
The Microchip (formerly Microsemi/Actel) A54SX72A-FG256M is a 72,000-gate antifuse FPGA from the SX-A family, delivering 108K system gates, 4,024 logic modules, and up to 217 MHz system performance in a 256-ball FBGA package with 203 user I/O. An antifuse FPGA is a type of field-programmable gate array whose interconnect elements are permanently programmed at power-up or via a programmer, rather than stored in a configuration SRAM cell. As a class of programmable logic devices (PLDs), antifuse FPGAs sit alongside SRAM FPGAs and flash FPGAs in the programmable logic hierarchy. Because the configuration is hard-wired, antifuse devices retain their programming through power cycles, are inherently immune to configuration readback, and offer lower static power and better SEU robustness than SRAM-based alternatives. Key features of the A54SX72A include a 0.25 um process technology, a single 2.5V core supply, and clock resources including dedicated CLKA and CLKB global clocks plus quadrant clocks (QCLK) for localized timing domains. The SX-A architecture uses a sea-of-modules structure with combinational and sequential logic modules, enabling high gate utilization typical of Actel antifuse families. Technically, the device's 4,024 cells implement both combinational and registered functions, and the 217 MHz figure reflects the family's toggling-rate capability, suitable for glue logic consolidation, bus bridging, and state-machine implementations. The antifuse interconnect provides deterministic, one-time programmable routing that eliminates configuration-time boot delays - a distinct advantage over SRAM FPGAs in systems requiring instant-on operation. Typical applications include industrial control, communications and networking line cards, avionics and military subsystems where configuration security matters, and single-chip integration of multiple discrete logic functions for system-wide cost savings. When designing with this device, plan pin assignment carefully: antifuse FPGAs are one-time programmable, so a design error requires a new device rather than a simple reconfiguration. Verify I/O standards and power sequencing against the SX-A family datasheet before committing the design.
