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.

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.

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.

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.

The Microsemi (Actel, now Microchip) A54SX08-VQ100 is an SX-family antifuse FPGA with 8,000 system gates, 512 logic modules, up to 240 MHz system performance, and 81 user I/Os, housed in a 100-pin TQFP/VQFP (14x14 mm) package. It operates from dual supply rails of 3.0 V to 3.6 V and 4.75 V to 5.25 V. An FPGA (Field-Programmable Gate Array) is a semiconductor device containing programmable logic blocks and interconnects that designers configure after manufacturing. Unlike SRAM-based FPGAs, the Actel SX family uses antifuse programmable interconnect, which is one-time programmable: the configuration is permanent, immune to configuration readback attacks, needs no external boot flash, and powers up instantly with the design already loaded. The SX family features a sea-of-modules architecture delivering ASIC-like density and performance. The A54SX08 offers 0.35 um process technology, 512 register cells, toggle rates to 240 MHz, and a flexible I/O structure supporting 3.3 V and 5.0 V signaling. The antifuse fabric also yields very low static power and high resistance to SEU configuration upsets compared with SRAM FPGAs. Architecturally, the SX device is organized as an array of logic modules surrounded by horizontal and vertical routing channels, with dedicated clocks and I/O modules around the periphery. Logic is implemented in combinatorial and sequential modules that map efficiently from Verilog or VHDL via the Actel/Microchip Libero design flow. Typical applications include glue logic integration, bus bridging, industrial control, communications line cards, mil-aerospace sub-systems, and replacement of multiple discrete 74-series devices where boot-time, security, and radiation tolerance of configuration matter. A key design consideration is that antifuse devices are one-time programmable: prototype carefully and reserve spare gates and I/Os for late changes, since the programmed device cannot be reconfigured in-system.
