A54SX72A-1CQ256 - SX-A 108K-Gate Antifuse FPGA | Microchip
The Microchip Technology A54SX72A-1CQ256 is a 108,000-system-gate antifuse FPGA from the SX-A family, implemented in 0.25 um process technology, operating from a single 2.5 V supply in a 256-pin ceramic CQFP (BFCQFP with tie bar) surface-mount package with 203 user I/O pins. 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. This page synthesizes verified distributor data, drop-in same-package alternatives, and practical design guidance not found in the manufacturer datasheet, giving engineers a single citation-ready reference.

A54SX72A-1CQ256B - 108K-Gate Antifuse FPGA | Microchip
The Microchip Technology (formerly Microsemi/Actel) A54SX72A-1CQ256B is a 108,000-system-gate antifuse FPGA from the SX-A family, offering 6,036 logic array blocks (LABs) and 203 user-programmable I/O pins in a 256-pin ceramic BFCQFP (CQ256) package with tie bar and 0.5 mm lead pitch. 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.
A54SX72A-1CQ256M - 108K Gate Antifuse FPGA, 2.5V | Microchip
The Microchip Technology A54SX72A-1CQ256M is an SX-A family antifuse FPGA with 108,000 system gates (72,000 raw gates, 4,024 logic cells), 213 user I/O pins, and a 2.5V core supply, housed in a 256-pin CQFP (75x75 mm) ceramic package - specifically a 256-BFCQFP with tie bar for surface-mount assembly. 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.

A54SX72A-1FG256 - 108K-Gate SX-A Antifuse FPGA | Microchip
The Microchip Technology A54SX72A-1FG256 is a 108,000-system-gate antifuse FPGA from the SX-A family, implemented on a 0.25 um CMOS process, offering 6036 Configurable Logic Blocks (CLBs), a maximum toggle rate of 250 MHz, and 203 user I/Os in a 256-ball Fine-Pitch Ball Grid Array (FBGA-256) package with 1 mm ball pitch. 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. This page synthesizes verified distributor pricing, same-family drop-in speed-grade and temperature-grade alternates, and practical design notes not found in the manufacturer datasheet.
A54SX72A-1FG256I - 72K Gate Antifuse FPGA 2.5V | Microchip
The Microchip Technology (formerly Actel/Microsemi) A54SX72A-1FG256I is an SX-A family antifuse FPGA with 72K gates (108K system gates), 4024 logic cells, 250 MHz system performance, 2.5V core supply, and 203 user I/O in a 256-ball FBGA package (17x17x1.97 mm), industrial temperature grade, supplied in tray. 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.

A54SX72A-1FG256M - 108K-Gate Antifuse FPGA, 256-FBGA | Microchip
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.

A54SX72A-1FG484M - 108K-Gate Antifuse FPGA 484-BGA | Microchip
The Microchip Technology A54SX72A-1FG484M is an SX-A family antifuse FPGA with 108,000 system gates, 360 user I/Os, and 250 MHz system performance, housed in a 484-ball FBGA package and rated for the -55C to +125C military temperature range. 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. This page synthesizes distributor pricing context, drop-in same-package alternatives, and practical design notes not found in the manufacturer datasheet.
A54SX72A-1FGG256 - 108K-Gate Antifuse FPGA, 256-FBGA | Microchip

An antifuse FPGA is a type of field-programmable gate array whose interconnect programming elements are one-time programmable antifuse cells. Within the programmable logic hierarchy, the A54SX72A sits at the top of the SX-A family (FPGA -> antifuse FPGA -> one-time-programmable programmable logic device), offering non-volatile configuration without a configuration boot device, which distinguishes it from SRAM-based FPGAs. 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.

An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a fabric of programmable logic blocks and interconnects that designers configure to implement custom digital circuits. Within the programmable logic hierarchy, the SX-A family sits under one-time-programmable (OTP) antifuse FPGAs, a category valued for instant-on startup, low power, and high design security compared to SRAM-based FPGAs. Key features include a 0.25 um CMOS antifuse architecture with no configuration memory to load (achieving full function at power-up), 2.5V single-supply operation that reduces power versus 3.3V fabrics, quadrant and global clocking resources (CLKA, CLKB, and QCLK networks on the A54SX72A), and the secure -1 speed grade for industrial temperature ranges of -40C to +85C. The antifuse fabric provides inherent resistance to bitstream extraction and cloning because no configuration data exists externally, making the device attractive for defense, avionics, and industrial systems where IP protection matters. The 250 MHz toggle capability supports high-speed state machines, glue logic consolidation, and bus interfacing. Typical applications include aerospace and defense control logic, industrial automation controllers, telecommunications line cards, and single-chip integration of multiple ASSP/glue-logic functions to reduce board count and bill-of-material cost. Design consideration: because SX-A devices are one-time programmable, verify the final netlist thoroughly in simulation and with the Silicon Explorer II debugging tool before programming production units.

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. This page synthesizes distributor pricing, package-specific FPGA alternatives, and practical design guidance that is not always repeated in the manufacturer datasheet, with data verified from Microchip and authorized distributor sources as of 2026-09-03.

Key features of the A54SX72A include 108K system gates of register-rich logic (6,036 modules / 4,024 cells organization), 250 MHz toggling capability in 0.25 um CMOS, single-chip integration that replaces multiple glue-logic devices, and a wide supply window specified around a 2.5 V nominal rail. The -1 speed grade is the standard commercial grade, rated for 0 C to +70 C ambient operation. Architecturally, the SX-A array is organized as a sea of combinational and sequential logic modules interconnected by antifuse-programmed routing channels, with dedicated global and quadrant clock resources (CLKA, CLKB, QCLK) described in the Microchip SX-A family datasheet for high-fanout, low-skew clocking. Typical applications include industrial control and automation, communications and networking line cards, test and measurement instrumentation, avionics and defense subsystems requiring OTP security, and glue-logic consolidation in embedded systems. Design consideration: because the device is one-time programmable, verify your design thoroughly in simulation before programming, and reserve spare I/O and logic margin for field fixes since no rework is possible.

A54SX72A-1FGG484I - 108K-Gate Antifuse FPGA 484-BGA | Microchip
The Microchip Technology A54SX72A-1FGG484I is an SX-A family antifuse FPGA with 108,000 system gates (72,000 typical gates), 4024 logic cells, up to 360 user I/O, and a 250 MHz system performance rating, housed in a 484-ball Fine-Pitch Ball Grid Array (FBGA/FGG484) package for industrial temperature 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
The Microchip Technology (formerly Microsemi/Actel) A54SX72A-1FGG484M is an SX-A family antifuse FPGA with 108K system gates, 72K usable gates, 360 user I/O, and a 250 MHz system performance rating, housed in a 484-ball Fine-Pitch Ball Grid Array (FBGA-484) with 1 mm ball pitch. 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.

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.

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.
