A54SX08-1TQG144 - 8K Gate SX FPGA, 113 I/O, TQFP-144 | Microsemi
The Microsemi (Microchip) A54SX08-1TQG144 is an 8,000-gate Actel SX-family antifuse FPGA with 768 logic cells, 113 user I/O, up to 280 MHz system performance, and a 144-pin TQFP (20x20 mm, 0.5 mm pitch) surface-mount package operating from 3.3V/5V supplies. A Field Programmable Gate Array (FPGA) is a semiconductor device containing a fabric of configurable logic blocks and programmable interconnects that designers configure in the field to implement custom digital circuits. Within the programmable logic hierarchy, the FPGA sits above CPLDs and PAL/GAL devices, offering higher gate counts and register-rich architectures. The Actel SX family is distinctive because it uses antifuse programming: one-time programmable connections that retain configuration through power cycles with no external configuration memory required. Key features of the A54SX08-1TQG144 include the SX sea-of-modules architecture delivering 280 MHz-class performance, a 0.35 um CMOS process, 113 user I/O in a compact 144-TQFP footprint, and single-chip antifuse configuration that eliminates the boot-time and configuration-store complexity of SRAM FPGAs. The -1 speed grade denotes the standard speed bin of the SX family. Technically, the SX family's sea-of-modules architecture provides a high ratio of usable registers to gates, which benefits high-speed state machines, bus interfacing, and glue-logic consolidation. Antifuse interconnect also yields low static power and inherent resistance to configuration upset, a property that made SX devices popular in industrial, communications, and aerospace-adjacent designs. Typical applications include industrial control and automation, bridge and interface logic between incompatible bus standards, high-speed state machines, and redesign/obsolescence replacement of older ASIC or PAL/PLD circuits where a proven 5V-tolerant, non-volatile FPGA is preferred. Design consideration: because the device is one-time programmable, verify the design fully in simulation before programming; plan I/O assignments against the 144-TQFP pinout early, and budget power for 3.3V core/5V-tolerant I/O conditions per the SX family datasheet.

A54SX08-1TQG144I - 8K-Gate Antifuse FPGA, 280MHz | Microsemi
The Microsemi A54SX08-1TQG144I is an 8,000-gate Actel SX-family antifuse FPGA with 512 logic cells, up to 280 MHz system performance, and 113 user I/O, housed in a 144-pin TQFP (20x20 mm) surface-mount package rated for -40C to +85C industrial operation. An antifuse FPGA is a type of field-programmable gate array whose interconnects are permanently configured by programmable antifuse elements rather than SRAM configuration cells. Within the programmable logic hierarchy (FPGA -> programmable logic device -> semiconductor), antifuse devices occupy the one-time-programmable (OTP) niche, offering non-volatility, immunity to configuration readback, and very low standby power in exchange for a single programming cycle. Key features of this device include the sea-of-modules Actel SX architecture built on a 0.35 um CMOS process, dual supply operation of 3.3V (3V to 3.6V core) and 5.0V (4.75V to 5.25V) I/O, and the -1 speed grade supporting toggle rates up to 280 MHz. The 113 user I/O pins support both 3.3V and 5V signaling, simplifying integration into legacy 5V industrial systems. Architecturally, the SX family combines C-cell (combinational) and R-cell (sequential) modules in a fine-grained sea-of-modules array, delivering gate-density efficiency and deterministic routing delays closer to a gate array than a typical SRAM FPGA. Programming is performed post-assembly via the antifuse network, eliminating the need for external configuration memory such as a serial flash, which improves system reliability and reduces board area. Typical applications include industrial control and automation, glue-logic consolidation in mixed 3.3V/5V systems, aerospace and defense sub-systems requiring non-volatile instant-on logic, and communication equipment backplanes where configuration readback must be impossible for security reasons. When designing with the A54SX08-1TQG144I, remember the OTP nature: the functional design must be final before programming, so use the Libero/Designer flow with thorough simulation. Power the 5V I/O bank within the 4.75V to 5.25V window to guarantee valid logic levels.

A field-programmable gate array (FPGA) is a semiconductor device containing a matrix of configurable logic blocks and programmable interconnects that designers configure in the field after manufacturing. FPGAs sit above fixed-function ASSPs in the programmable logic hierarchy (FPGA -> programmable logic device -> digital IC -> semiconductor). The SX family uses a one-time-programmable antifuse architecture, meaning configuration is permanent, non-volatile, and immune to configuration-upset issues that affect SRAM FPGAs. Key features include 0.35 um CMOS antifuse technology for non-volatile, instantly-on configuration; dual-rail supply supporting both 3.3 V (3.0-3.6 V) and 5 V (4.75-5.25 V) I/O environments; 768 logic array blocks (LABs) providing usable logic density equivalent to 12,000 system gates; and a low-cost 176-TQFP surface-mount package with 128 available user I/O pins. Architecturally, the SX family organizes logic into modules within logic array blocks, connected through a segmented routing fabric. The -1 speed grade supports internal toggle rates up to 280 MHz in typical designs, sufficient for glue logic, state machines, bus bridging, and moderate-speed datapath functions. Typical applications include industrial control and automation boards, legacy aerospace and defense system sustainment, telecommunications line-card glue logic, and embedded system bus interfacing where instant-on, non-volatile configuration is required. A key design consideration is that antifuse FPGAs are one-time programmable: design changes require a new physical device, and designer verification (via Actel/Microsemi Libero-style toolchains) must be complete before programming.

A54SX08-1TQG176I - 12K-Gate SX FPGA, 176-TQFP | Microsemi
The Microsemi (Actel) A54SX08-1TQG176I is an SX-family antifuse Field Programmable Gate Array (FPGA) with 12,000 system gates, 512 logic cells (768 logic array blocks), and 128 user I/Os, housed in a 176-pin TQFP (24x24 mm) package rated for the industrial temperature range. An FPGA is a programmable logic device that implements custom digital circuits by configuring a fabric of logic blocks and interconnect. The SX family belongs to the higher tier of the Actel/Microsemi FPGA hierarchy, sitting above the ACT-series FPGAs and using a sea-of-modules antifuse architecture that delivers application-specific-IC-like performance and routing density in a one-time-programmable device. Unlike SRAM FPGAs, the antifuse configuration is non-volatile, radiation-tolerant by nature, and requires no configuration PROM, simplifying the bill of materials and improving design security. Key features include a 0.35 um process technology with toggle rates up to 280 MHz, dual supply voltage operation (3.0 V to 3.6 V core and 4.75 V to 5.25 V I/O per Microchip USA data), and 128 programmable user I/Os configurable for interfacing with 5 V-tolerant peripheral systems. The -1 speed grade balances performance with power, and the industrial I-suffix rating supports operation in harsh environments. The sea-of-modules architecture uses two module types, combinational and sequential, in an 8:2 ratio, providing efficient implementation of both wide and narrow logic functions with predictable, low-skew timing. Because routing is fixed at programming time via antifuse links, the device exhibits deterministic interconnect delays that simplify static timing analysis. Typical applications include industrial control and automation, communications and networking glue logic, bridge and interface logic, and defense/aerospace embedded control where one-time programmability and configuration immunity are valued. Design consideration: as a one-time-programmable antifuse device, functional errors cannot be re-fixed in the field, so complete simulation with the Libero/Designer flow is mandatory before programming.

An FPGA is a type of programmable logic device (PLD) that implements digital logic through configurable interconnect and logic blocks programmed by the designer, sitting above fixed-function ASICs in flexibility and below general-purpose processors in abstraction. Within the hierarchy of digital ICs, the Actel SX family belongs to the antifuse-based, one-time-programmable FPGA class, where configuration data is permanently stored in antifuse elements rather than SRAM cells. Key features include the SX sea-of-modules architecture delivering ASIC-like performance, dual supply voltage operation (3.0V to 3.6V core region and 4.75V to 5.25V I/O region per the 3.3V/5V dual-supply scheme), and a 0.35um process technology. The one-time-programmable antifuse fabric makes the device non-volatile, secure against readback, and immune to configuration errors at power-up, which differentiates it from SRAM FPGAs such as the Xilinx XC4000 or Altera FLEX families. Architecturally, the sea-of-modules structure provides high logic density and predictable timing: the 512 combinational and sequential cells connect through a routing fabric optimized for high fan-out, enabling the 280 MHz maximum toggle frequency. The 81 user I/O pins support the 5V-compatible signaling standards required in legacy industrial and avionics systems. Typical applications include industrial control and automation, glue logic integration, high-reliability power-up-critical control logic, and communication backplane interfaces where one-time programmability and 5V I/O tolerance remain design requirements. Design consideration: because antifuse programming is irreversible, verify the design fully in simulation and with the Actel/Microchip Libero design flow before programming production units.

A54SX08-2FG144 - 8K-Gate SX FPGA 320MHz 144-FBGA | Microchip
The Microchip Technology (Actel) A54SX08-2FG144 is an antifuse-based FPGA from the SX-A family delivering 8,000 equivalent system gates (12,000 system gates per distributor data) implemented in 768 configurable logic blocks (512 logic cells), with up to 111 user I/Os and a maximum toggle rate of 320 MHz, housed in a 144-ball fine-pitch BGA (FBGA) package measuring 12 x 12 mm with a 1.00 mm ball pitch. A Field Programmable Gate Array (FPGA) is a semiconductor device containing a matrix of configurable logic blocks and programmable interconnects that the designer wires together to implement custom digital hardware. Within the programmable logic hierarchy, the FPGA sits above CPLDs and SPLDs, and the antifuse-based SX-A subfamily belongs to the one-time-programmable (OTP) class of FPGAs, which retain their configuration permanently and need no configuration ROM or boot sequence. Key differentiating features include the sea-of-modules architecture, which achieves pin-to-pin propagation delays as low as 0.4 ns on FastConnect paths; dual 3.3V/5.0V supply operation supporting mixed-voltage system designs; and nonvolatile antifuse programming, which eliminates configuration time, reduces bill-of-materials cost, and provides inherent resistance to configuration corruption and radiation-induced configuration upsets compared with SRAM FPGAs. Technically, the device is fabricated in a 0.35 um CMOS process and uses DirectConnect, FastConnect, segmented routing, and high-drive routing resources to balance speed and routability. The '-2' speed grade offers the family's fastest timings, and the trade-off for this performance is OTP flexibility: logic changes require a new device rather than a reflash, so designs must be fully verified before production. Typical applications include high-performance glue logic consolidation, bus interfacing and bridge functions, industrial control state machines, communications line cards, and military/aerospace subsystems where antifuse immutability is an advantage. Designers should budget I/O assignment carefully, since OTP devices cannot be reprogrammed; use the Libero SoC design flow from Microchip for synthesis, place-and-route, and timing sign-off at the -2 speed grade.

Because the configuration is stored in antifuse elements, the device is nonvolatile and instantly operational at power-up with no external configuration ROM and no configuration-time vulnerability. Architecturally, each SX logic module is a multiplexer-based cell whose small grain minimizes routing delay, which is why the family achieves ASIC-like timing predictability. Routing resources are organized for short, deterministic interconnect, so designers can meet timing without extensive place-and-route iteration. The dual 3.3V/5V I/O capability allows direct interfacing with legacy 5V TTL systems while the core runs at 3.3V. Typical applications include industrial control and automation, 5V-legacy bus bridging, telecommunications line-card glue logic, and avionics/industrial systems where instant-on, single-chip operation and resistance to configuration corruption are required. Industrial-grade (-I suffix) screening suits harsh environments. Design consideration: the antifuse fabric is one-time-programmable, so programming errors cannot be recovered; prototype on the identical die in a reprogrammable flow or verify the design thoroughly before committing to production programming.

An FPGA (Field Programmable Gate Array) is a semiconductor device containing an array of programmable logic blocks and reconfigurable interconnects that the designer wires together after manufacturing. Within the programmable logic hierarchy, the SX family sits under Actel/Microsemi antifuse FPGAs, one-time programmable (OTP) devices that sit alongside FPGA -> programmable logic -> digital IC in the component taxonomy. Key features include one-time-programmable antifuse architecture with live-at-power-up operation and no configuration PROM, 768 logic array blocks (LABs), pin-to-pin family scalability, and a matte-tin lead finish. Antifuse programming also improves immunity to configuration corruption, a key reliability advantage over SRAM FPGAs in harsh environments. Architecturally, the SX family uses a sea-of-modules grid with combinational and sequential logic cells connected through segmented antifuse routing. The 0.35 um process yields predictable timing; the -2 grade provides the fastest commercial speed bin, and the 5V-tolerant I/O simplifies interfacing to legacy 5V TTL systems. Typical applications include industrial control glue logic, bus interface bridging, communications and networking line cards, and aerospace/defense designs needing OTP configuration. The 144-TQFP balances I/O count and board area for mid-density designs. Design consideration: antifuse devices are OTP, so reserve spare logic and I/O in your design and fully validate the netlist before programming, since a programming error cannot be corrected in-circuit.

The Microsemi A54SX08-2TQG144I is an SX-family antifuse Field Programmable Gate Array (FPGA) with 8,000 system gates, 512 logic cells, a system performance of up to 320 MHz, and 113 user I/O pins, housed in a 144-pin TQFP (20x20 mm) industrial package. It operates from dual supply rails of 3.3V (3.0V to 3.6V) and 5V (4.75V to 5.25V). An FPGA (Field Programmable Gate Array) is a semiconductor device containing configurable logic blocks and programmable interconnects that the designer programs after manufacturing. Within the programmable logic hierarchy, FPGAs sit above CPLDs and SPLDs in logic density and are classified as programmable logic ICs or embedded FPGAs. The Actel SX family pioneered a sea-of-modules antifuse architecture that delivers ASIC-like performance and integration levels, making it distinct from SRAM-based FPGAs because programming is permanent, radiation-tolerant by nature, and requires no configuration boot device. Key features of the A54SX08-2TQG144I include the -2 speed grade for high system clock rates up to 320 MHz, 0.35um antifuse process technology, industrial temperature rating (I suffix, -40C to +85C operating range), and dual 3.3V/5V supply operation that simplifies integration into mixed-voltage legacy systems. The 0.5 mm pin pitch TQFP package enables conventional surface-mount assembly. Technically, the sea-of-modules architecture uses a proprietary antifuse interconnect that adds negligible routing delay compared to SRAM-switch FPGAs, giving deterministic, low-jitter timing. Logic density of 8K gates suits state machines, bus interfaces, glue logic consolidation, and high-speed control paths where flash- or SRAM-based devices cannot meet timing. Typical applications include industrial automation control, telecommunications line cards, military/aerospace subsystems requiring non-volatile instant-on logic, and legacy 5V system upgrades. Design consideration: antifuse devices are one-time programmable - there is no in-system reprogramming, so complete design verification before programming is essential.

A54SX08-2TQG176I - SX FPGA 12K Gates 176-TQFP | Microsemi
The Microsemi (Microchip Technology) A54SX08-2TQG176I is an SX-family antifuse FPGA with 12,000 system gates, 768 logic array blocks (LABs), 128 user I/O pins, and a -2 speed grade, housed in a 176-pin TQFP (24x24 mm) surface-mount package. It operates from 3.3V (3.0V to 3.6V) or 5V (4.75V to 5.25V) supplies and is fabricated in 0.35um CMOS technology. An FPGA (Field-Programmable Gate Array) is a semiconductor device that implements digital logic through configurable interconnects and logic blocks programmed by the designer rather than fixed at the silicon factory. The SX family uses Microsemi antifuse programming technology, which is one-time programmable (OTP), making configured logic non-volatile, immediately active at power-up, and inherently more resistant to configuration corruption than SRAM-based FPGAs. Key features of the A54SX08-2TQG176I include 512 logic cells organized into 768 LABs/CLBs, support for system clock rates up to 320 MHz in the SX family architecture, dual 3.3V/5V I/O operation enabling direct interfacing with legacy 5V TTL systems, and the industrial temperature-grade I suffix for extended-environment deployment. The -2 speed grade designation indicates a mid-range timing bin within the family, balancing propagation delay against cost. Technically, the SX architecture places flip-flops and combinational logic in efficient module cells, with 0.35um antifuse interconnect yielding low on-resistance paths and deterministic timing. Because configuration is stored physically in antifuse elements rather than loaded from an external flash, the design is protected from readback, supporting secure and high-reliability applications. Typical applications include industrial control logic, glueless bus interfacing between 5V and 3.3V subsystems, aerospace and defense support logic, and communications equipment state machines where instant-on operation is required. Design consideration: antifuse FPGAs are one-time programmable, so design changes require a new physical device; verify the bitstream thoroughly in simulation and with engineering-lot programming before committing production units.

A54SX08-2VQG100 - SX FPGA 12k Gates 100-TQFP | Microchip
The Microchip Technology (Microsemi) A54SX08-2VQG100 is an SX-family antifuse Field Programmable Gate Array (FPGA) with 12,000 system gates, 768 logic elements, and 81 user I/O pins, housed in a 100-pin TQFP (14x14 mm, VQG100) surface-mount package. It operates from dual supply rails of 3V to 3.6V (core) and 4.75V to 5.25V (I/O), with speed grade 2 timing. An antifuse FPGA is a one-time-programmable logic device that forms permanent interconnects at programming time. Within the power-management hierarchy of programmable logic, the SX family sits among low-cost, high-reliability, non-volatile FPGAs: unlike SRAM FPGAs, it requires no configuration ROM, boots instantly at power-up, and resists configuration upset from radiation or power glitches, which is why antifuse FPGAs remain popular in aerospace, industrial, and long-lifecycle embedded systems. Key features of the A54SX08-2VQG100 include its SX logic architecture with 768 logic elements for moderate-density glue logic, control, and interface functions; 81 user I/O supporting legacy 5V-tolerant signaling via the 5V rail; and speed grade 2 performance suited to state machines, bus interfaces, and address decoding. The dual-rail architecture separates the 3.3V core from the 5V I/O supply, simplifying integration into older 5V bus systems. Technically, the SX family uses a sea-of-modules architecture with fine-grained combinational and sequential building blocks. Antifuse interconnect provides low on-resistance routing with no configuration memory, contributing to instant-on behavior, low static configuration risk, and long-term bitstream integrity over decades of deployment. Typical applications include industrial control and automation glue logic, telecommunications line-card interface bridging, legacy 5V system upgrades, test and measurement board logic, and defense/aerospace subassemblies where deterministic non-volatile configuration is required. When designing with this device, note that it is one-time programmable: prototype with the appropriate development flow (Libero SoC or legacy Designer software) before committing hardware, and plan I/O budgets since 81 user I/O is fixed per device.

The Microsemi (Microchip) A54SX08-2VQG100I is an SX-family antifuse FPGA with 8K system gates, 512 logic cells, 81 user I/Os, and a 320 MHz system performance rating in a 100-pin VQFP/TQFP surface-mount package, fabricated on a 0.35 um process and operating from 3.3V core supply with 5V-tolerant I/O capability. The industrial-grade I suffix covers operation from -40C to +85C. A field-programmable gate array (FPGA) is a semiconductor device containing programmable logic blocks and interconnects that the designer configures after manufacturing. Within the programmable logic hierarchy, the FPGA sits above CPLDs in gate density and flexibility, and the SX family uses Actel antifuse technology, which is one-time programmable. Antifuse configuration data is permanently stored in silicon, giving the device inherent resistance to configuration readback, bit-flip errors from radiation, and cloning - a key advantage over SRAM FPGAs that load configuration from external memory at power-up. Key features of the A54SX08 include the proprietary Act-1/Act-2 style logic module architecture delivering 512 cells of combinational and sequential logic, 320 MHz internal toggle capability suited to state machines and glue logic, and dual-voltage operation of 3.3V and 5V that simplifies interfacing with legacy 5V TTL systems common in industrial and defense equipment. The one-time-programmable antifuse interconnect eliminates configuration PROMs, reducing bill-of-materials count and board area. Technically, the SX family's fine-grained architecture routes signals through a segmented routing fabric with low interconnect capacitance, which is the basis of its deterministic, predictable timing compared to coarser SRAM-based architectures. Designers implement designs using the Microsemi (Microchip) Libero SoC design suite, and timing analysis can be performed before layout because of the deterministic interconnect delays. Typical applications include industrial control glue logic, bridge and interface translation between 5V and 3.3V subsystems, secure or high-reliability control logic where configuration data must not be read out, and obsolescence-driven redesigns replacing multiple discrete TTL/CMOS devices with one FPGA. A key design consideration: because the device is one-time programmable, the bitstream cannot be updated in the field - verify the design thoroughly in simulation and hardware testing before programming, and include an I/O margin plan for the 5V-tolerant interface banks.

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. Within the programmable-logic hierarchy, the SX family occupies the high-speed antifuse segment: device -> FPGA -> antifuse FPGA -> Actel/Microchip SX family. Unlike SRAM-based FPGAs, antifuse FPGAs are non-volatile and configure once, which makes them resistant to configuration upset and unsuitable for repeated reprogramming. Key features include 8,000 system gates organized as 512 cells in a sea-of-modules architecture, 111 user-input/output capability on the 144-ball package, I/O operation from 3.3V and 5V supply domains, and high-speed performance suited to state machines, bus bridging, and glue logic consolidation. The sea-of-modules architecture delivers routing efficiency and deterministic timing that simplify high-speed design closure. Technically, the SX family is fabricated on a 0.35 um CMOS process and uses Actel's antifuse interconnect, which provides low on-resistance, low parasitic capacitance routing segments. This yields higher toggle rates and lower interconnect delay than contemporary SRAM routing switches, contributing to the family's 240 MHz class performance in performance-intensive applications. Typical applications include industrial automation control, telecommunications and networking interface logic, military/aerospace systems requiring one-time-programmable non-volatile configuration, and embedded bridge or protocol-glue logic where 5V-tolerant I/O eases interfacing with legacy circuits. Designers should note that antifuse devices are one-time programmable: the design must be finalized before programming, and design iterations require a new device. Choose the -I temperature-grade suffix (A54SX08-FG144I) for industrial -40C to +85C environments.

The Microchip (Microsemi/Actel) A54SX08-FG144I is an 8,000-system-gate antifuse FPGA from the SX family, offering 512 logic cells, system performance up to 240 MHz, and 111 user I/O in a 144-ball FBGA (FG144) package with industrial temperature rating of -40C to +85C. The device operates from a 3.3V core with 5V-tolerant I/O capability and is fabricated on a 0.35 um process. A field-programmable gate array (FPGA) is a semiconductor device containing a matrix of configurable logic blocks and interconnects that the designer programs to implement custom digital circuits. The SX family sits within the broader programmable logic hierarchy as a high-speed, one-time-programmable (OTP) antifuse FPGA family, positioned for performance-intensive glue logic, bus bridging, and system integration tasks where SRAM FPGAs would need external boot configuration devices. Key differentiating features of the A54SX08-FG144I include the Actel sea-of-modules architecture, which delivers ASIC-like routability and predictable timing; the antifuse programming technology, which is non-volatile, rugged, and immune to configuration readback attacks; and 5V-tolerant I/O that simplifies interfacing with legacy 5V systems. The 240 MHz system-level toggle capability makes it suitable for high-throughput datapath functions. Technically, the SX family uses a fine-grained sea-of-modules array of C-cells (combinational logic) and R-cells (registers), with a routing fabric implemented in metal layers above the antifuse program elements. The 0.35 um CMOS process provides a stable, mature silicon platform. Programming is performed once at programming stations (e.g., Silicon Sculptor), after which the configuration is permanent and power-on immediate - no configuration PROM or configuration time is required. Typical applications include industrial control and automation, military and avionics subsystems, telecommunications line cards, bus interface and bridge logic, and refresh or redesign of legacy systems that originally used the Actel SX family. The 111 available user I/O covers wide parallel bus interconnection in a compact 144-ball package. A key design consideration: because antifuse FPGAs are one-time programmable, designers must fully verify the design in simulation before committing silicon, and a reprogramming cycle requires a new physical device. Plan spare devices into the build budget.

A54SX08-FGG144 - SX FPGA 8K Gates 144-FBGA | Microchip
The Microchip Technology A54SX08-FGG144 (originally Actel/Microsemi) is an SX-family antifuse FPGA with 8K system gates, 512 logic cells, a maximum toggle rate of 240 MHz, and 111 user I/Os, housed in a 144-ball FBGA (LBGA) surface-mount package. An FPGA (Field-Programmable Gate Array) is a semiconductor device that implements custom digital logic through programmable interconnect and configurable logic blocks. Within the programmable logic hierarchy, the SX family occupies the high-performance, non-volatile segment: unlike SRAM FPGAs, its antifuse fabric is programmed once at the factory or in-house, retains configuration through power cycles, and needs no configuration PROM or boot sequence. This makes it a direct ancestor of the modern power-management and logic-integration role played by one-time-programmable FPGAs in aerospace and industrial systems. Key features of the A54SX08-FGG144 include a 0.35 um antifuse process technology, dual supply operation (core at 3.3V with 5V-tolerant I/O support per the 3.3V/5V operating ranges of 3V-3.6V and 4.75V-5.25V), and a sea-of-modules architecture that delivers high routing efficiency and predictable timing. With 768 LABs and 512 logic cells, it suits moderate-density glue logic, bus interfacing, and state-machine integration. The architecture uses Actel's proprietary antifuse interconnect, which adds near-zero parasitic capacitance on programmed paths - the reason SX devices achieve 240 MHz-class system performance in a mature process node. Non-volatility also yields instant-on behavior and strong resistance to configuration corruption, a key reliability benefit in harsh environments. Typical applications include industrial control and automation glue logic, communication bridge functions, legacy aerospace/defense subsystem upgrades, and power-on-critical control paths where a bitstream-loading FPGA is unacceptable. Design consideration: as a one-time-programmable device, any logic change requires a new programmed part - prototype thoroughly with simulation and, where possible, reserve the industrial-temperature A54SX08-FGG144I variant for extended-environment builds.

A54SX08-FGG144I - 8K Gate SX FPGA 240MHz 144-FBGA | Microchip
The Microchip (Microsemi) A54SX08-FGG144I is an SX-family field programmable gate array (FPGA) with 8,000 system gates, 512 logic cells, up to 111 user I/O, and 240 MHz internal performance, housed in a 144-ball fine-pitch FBGA (FGG144) package and rated for the industrial temperature range of -40C to +85C. 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 FPGA sits above CPLDs and below ASSPs/ASICs in integration, and the SX family belongs to the antifuse-based, nonvolatile class of FPGAs, meaning the configuration is permanently set at programming time and is retained without a configuration PROM or boot sequence. Key features of the A54SX08-FGG144I include a sea-of-modules architecture delivering up to 320 MHz internal toggle performance, 3.7 ns clock-to-out (pin-to-pin), 0.1 ns input setup, and 0.25 ns clock skew, making it suitable for high-speed glue logic, state machines, and interface bridging. The device is fabricated on a 0.35 um CMOS process and supports both 3.3 V and 5 V operating supply voltages, which simplifies integration into legacy 5 V industrial backplane systems alongside modern 3.3 V logic. The SX family's antifuse architecture provides two significant engineering advantages over SRAM FPGAs: the configuration is inherently nonvolatile and secure, and there is no need for external boot memory, reducing board area and configuration time to zero. Logic is implemented in efficient combinational and sequential modules that allow single-chip integration of functions previously requiring multiple CPLDs, with the datasheet highlighting 66 MHz PCI integration as a single-chip solution. Typical applications include industrial automation control, 66 MHz PCI interface bridging, telecommunications line-card glue logic, military/aerospace subsystems requiring nonvolatile configuration, and obsolescence-mitigation redesigns of legacy Actel-based designs. Designers should note that antifuse FPGAs are one-time programmable; a change in the netlist requires a new device, so reserve sufficient I/O margin and simulate thoroughly before committing. The 144-FBGA package requires careful ball-map verification against the latest Microchip datasheet before layout.

A54SX08-PLG84I - 8K Gate SX FPGA 69 I/O PLCC-84 | Microchip
The Microchip Technology (Microsemi/Actel) A54SX08-PLG84I is a member of the Actel SX family of field programmable gate arrays (FPGAs) offering 8000 equivalent system gates, 512 logic cells (768 CLBs), 69 user I/O, and a maximum toggle rate of 240 MHz in an 84-pin PLCC (J-Lead) surface-mount package measuring 29.31 x 29.31 mm. It operates from a dual supply of 3.0 V to 3.6 V and 4.75 V to 5.25 V and is rated for the industrial temperature range. An FPGA (Field Programmable Gate Array) is a semiconductor device containing configurable logic blocks (CLBs) and programmable interconnects that the designer wires together after manufacturing, unlike fixed-function ASICs. Within the programmable logic hierarchy, the SX family sits among antifuse-based one-time-programmable FPGAs, positioned above CPLDs in gate density and below modern SRAM FPGA families in capacity. The SX family uses a sea-of-modules architecture on a 0.35 um CMOS process, delivering ASIC-like performance and integration levels that Actel claimed were not achieved by other FPGA architectures of its era. Because the programming element is antifuse-based rather than SRAM-based, the configuration is retained permanently, requires no external boot PROM, and is inherently resistant to configuration upset - key reasons this family remains in long-lifecycle industrial, aerospace-adjacent, and defense-heritage designs. Combinatorial CLB delay is as low as 0.8 ns on faster speed grades, supporting performance-intensive glue logic, state machines, and bus-interface functions. Typical applications include legacy industrial control and automation boards, telecom line-card glue logic, motion-control sequencers, test and measurement backplanes, and obsolescence-management re-sourcing of 1990s-2000s programmable logic designs that cannot justify a board respin. When designing with this device, note the dual-rail power requirement (3.3 V core/5 V or 3.3 V I/O operation) and the one-time-programmable nature of the antifuse fabric - a programming error renders the device unusable, so design freeze and simulation sign-off should precede programming.

Key features include the Actel sea-of-modules architecture delivering gate-array-like performance, non-volatile antifuse programming that requires no configuration PROM and provides inherent resistance to configuration corruption, 512 logic modules in approximately 8K usable gates, and a broad 130-I/O budget in a surface-mount quad flatpack. Technically, the device is fabricated on a 0.35 um CMOS process. The antifuse architecture yields low routing delay and deterministic timing, historically making SX devices popular in high-reliability, military, and industrial systems where instant-on behavior and design security matter. Typical applications include glue-logic consolidation, bus interfacing and bridging, industrial control sequencing, and aerospace/defense subsystems that previously relied on the Actel SX family. Design consideration: antifuse FPGAs are one-time programmable - validate the bitstream thoroughly in simulation and on engineering silicon before production programming.
