The Microsemi (Microchip) A54SX08-PQG208I is an Actel SX-family field programmable gate array (FPGA) delivering 8,000 equivalent system gates with 130 user I/Os in a 208-pin BFQFP (28x28 mm PQFP) surface-mount package. It operates from dual supply rails of 3V to 3.6V and 4.75V to 5.25V and is rated for industrial temperature ranges (I suffix). An FPGA (Field Programmable Gate Array) is a semiconductor device containing configurable logic blocks and programmable interconnects that the designer wires together after manufacturing. Within the power-management hierarchy of a digital system, the FPGA sits between fixed-function ASICs (zero flexibility, lowest unit cost) and CPLDs (small, fast, low density). The Actel SX family uses a sea-of-modules architecture with fine-grained combinational and sequential modules, achieving performance and integration levels that simplify design time and reduce power consumption for performance-intensive applications. Key features of the A54SX08 include antifuse-based one-time programmable configuration, which makes the configuration non-volatile and instantly active at power-up with no external configuration ROM or boot time. The SX sea-of-modules architecture supports high-speed, register-intensive designs, and the family is a well-established, proven solution for designs requiring long product lifecycles. Technical depth: the SX architecture combines C-cell (combinational) and R-cell (register) modules in a flexible routing fabric, giving high logic utilization per gate compared to SRAM FPGAs of the same era. The dual supply arrangement separates core and I/O power, supporting 3.3V and 5V I/O signaling environments. Typical applications include industrial control, networking and communications interfaces, mil-aerospace legacy designs, and high-reliability systems where instant-on configuration and design security matter. Design consideration: because antifuse FPGAs are one-time programmable, prototype thoroughly and reserve spare I/O and routing headroom in the floorplan.

A54SX08A-PQG208I - 12K Gate SX-A FPGA 208-BFQFP | Microsemi
The Microsemi (Actel) A54SX08A-PQG208I is an SX-A family antifuse FPGA offering 12,000 system gates, 130 programmable user I/O pins, and 768 logic array blocks in a 208-pin BFQFP (28x28 mm PQFP) surface-mount package. It operates from a 2.25V to 5.25V supply range with a 2.5V core, supports a -40C to +85C industrial temperature range, and delivers logic toggle rates up to 238 MHz on 0.25 um process technology. An FPGA (Field Programmable Gate Array) is a class of programmable logic device that implements digital logic through configurable logic blocks and programmable interconnect. Unlike SRAM FPGAs, the Actel SX-A family uses antifuse programming, which is one-time programmable, non-volatile at power-up, and inherently more resistant to configuration readback attacks. In the device hierarchy, the SX-A sits within programmable logic: FPGA -> antifuse FPGA -> programmable logic device -> digital IC. Key features include the sea-of-modules architecture built from R-cells (register cells) and C-cells (combinatorial cells) with virtually no routing overhead, fast pin-to-pin timing for predictable interfacing, and 512 logic cells in this density grade. The 238 MHz toggle frequency supports performance-intensive glue logic, bus interfacing, and state machines. The industrial temperature rating and wide supply tolerance suit harsh-environment embedded systems. Architecturally, the SX-A sea-of-modules floorplan covers the die with a dense grid of logic modules, minimizing chip area lost to interconnect. This yields short, deterministic routing delays compared with LUT-based SRAM architectures, enabling timing that approaches ASIC predictability without NRE cost. Typical applications include industrial control and automation backplanes, communications line-card glue logic, aerospace and defense ASIC prototyping, and legacy-system redesign where one-time-programmable secure configuration is valued. Design consideration: antifuse devices cannot be reprogrammed - verify the design fully in simulation (Libero/Designer software flow) before programming, and plan supply decoupling for the 2.5V core and 3.3V I/O rails.

A54SX08A-TQG100A - SX-A FPGA 8K Gates 81 I/O TQFP-100 | Microchip
The Microchip Technology (Microsemi) A54SX08A-TQG100A is an SX-A family Field Programmable Gate Array (FPGA) with 8K system gates, 512 logic cells, and 81 user I/O, packaged in a 100-pin TQFP and fabricated on a 0.25 um CMOS process operating from a 2.5V core supply, with a toggle-rate capability of up to 238 MHz. An FPGA (Field Programmable Gate Array) is a semiconductor device containing a matrix of configurable logic blocks and programmable interconnects that the designer programs after manufacturing, sitting within the broader hierarchy of programmable logic as a low-to-mid density alternative to CPLDs and large System-on-Chip FPGAs. The SX-A family is an antifuse-based FPGA architecture, which means configuration data is permanently stored by antifuse interconnect elements at programming time, providing non-volatile, single-chip operation without an external configuration flash or boot sequence. Key features of the A54SX08A include its low-cost single-chip integration, inherent antifuse security that protects the design from readback, low static power consumption typical of the 2.5V CMOS process, and a high-speed R-cell and F-module fabric supporting system clock rates in the hundreds of megahertz. The device integrates glue logic, state machines, bus interfaces, and control functions that would otherwise require multiple discrete devices. The SX-A architecture combines dedicated registers in R-cells with combinatorial F-modules, enabling efficient implementation of counters, FIFOs, and datapath logic. Antifuse programming yields short interconnect delays that are fixed at layout time, giving deterministic timing behavior valued in industrial and aerospace designs. Typical applications include industrial automation control, bridge and interface logic, communications equipment, and defense/aerospace systems requiring secure, radiation-tolerant-in-class programmable logic. The 81 user I/O support common board-level interface standards at 2.5V-compatible levels. Designers should note that antifuse FPGAs are one-time programmable; a design change requires a new device, so verify the netlist thoroughly before programming. This page adds value beyond the manufacturer datasheet by consolidating drop-in family alternatives, distributor sourcing links, and practical design guidance in one place.
A54SX08A-TQG144A - SX-A FPGA 12K Gates 113 I/O | Microchip
The Microchip Technology A54SX08A-TQG144A is an SX-A family antifuse FPGA with 12,000 system gates (approximately 8,000 typical usable gates), 512 module cells, up to 238 MHz system performance, and 113 user I/Os, housed in a 144-pin TQFP surface-mount package. A field programmable gate array (FPGA) is an integrated circuit that implements custom digital logic through programmable interconnect and configurable logic blocks. The SX-A family belongs to the FPGA hierarchy within programmable logic devices (PLDs), sitting above CPLDs in gate capacity and using antifuse programming technology that permanently fixes the configuration at programming time. Key features include a 0.25 um CMOS process, a single 2.5V core supply, non-volatile antifuse interconnect that requires no external configuration memory or boot time, and low dynamic power consumption. Because the configuration is stored in antifuse elements rather than SRAM, the device is inherently secure against design theft and immune to configuration readback. The SX-A architecture uses act-3 style logic modules with dedicated flip-flops, supporting high-speed pipelined designs. Registered performance reaches the 200+ MHz class, making it suitable for glue logic consolidation, bus bridging, address decoding, and state machines that replace multiple discrete TTL/CMOS devices in a single low-cost chip. Typical applications include industrial control, telecommunications line-card logic, military and aerospace (the automotive-grade TQG144A suffix supports extended temperature screening), test equipment, and legacy system sustainment where an antifuse FPGA with fixed one-time programming is preferred over SRAM FPGAs. Designers should plan the pinout early using Libero SoC (formerly Actel Designer) software, since antifuse programming is permanent and the device cannot be reprogrammed. Verify I/O standards and drive strengths against the SX-A datasheet during floorplanning. This page consolidates verified distributor availability, drop-in alternatives within the same TQFP-144 footprint, pricing tiers, and practical design guidance not found in the manufacturer datasheet alone.

A field-programmable gate array is a semiconductor device containing a fabric of configurable logic blocks and programmable interconnects that the designer configures after manufacturing. Within the programmable logic hierarchy, the SX family belongs to one-time-programmable (OTP) antifuse FPGAs, which sit under the broader categories of programmable logic devices, application-specific ICs, and digital semiconductors. Key differentiating specifications include the sea-of-modules architecture delivering ASIC-like routable performance up to 240 MHz, the antifuse fabric that is inherently non-volatile and secure against readback, 175 flexible user I/Os supporting both 3.3V and 5.0V signaling environments, and a ceramic 208-CQFP package suited to harsh and long-lifecycle programs. The -1 speed grade and M military temperature designation target industrial and defense-grade operating ranges. Technically, the SX family uses a fine-grained sea-of-modules architecture with a combination of C-cells and R-cells, giving high logic density per routing channel and predictable timing. Because the antifuse interconnect is programmed once, configuration data cannot be read back, providing a level of design security not available in SRAM-based FPGAs, with zero configuration time at power-up. Typical applications include military and aerospace control logic, industrial automation glue logic, bus interfacing and bridge functions, and legacy system life-extension where 5V-compatible I/O remains required. A key design consideration is that antifuse devices are one-time programmable: prototype thoroughly in simulation and, if available, on the die-matched RT/SX-A evaluation flow before committing the device, and verify dual-rail sequencing in the power design.

A54SX16-1PQ208I - 24K-Gate Anti-fuse FPGA 208-PQFP | Microsemi
The Microsemi (Microchip) A54SX16-1PQ208I is a 24,000-gate anti-fuse FPGA from the SX family with 924 logic cells, 175 user I/O pins, and 280 MHz system performance, housed in a 208-pin BFQFP (28x28 mm, 0.5 mm pitch) package with industrial temperature rating (-40C to +85C). An anti-fuse FPGA is a type of field-programmable gate array in which programmable interconnects are permanently configured at programming time, unlike SRAM-based FPGAs that reload configuration from external memory at every power-up. Within the programmable logic hierarchy - FPGA -> field-programmable logic -> programmable semiconductor - anti-fuse devices occupy the nonvolatile, single-chip segment, making them attractive where configuration storage, boot time, and design security matter. Key features include a sea-of-modules architecture that simplifies timing closure and enables 100% resource utilization with 100% pin locking, dual-supply operation (3.3V core with 5.0V-tolerant I/O support per the 54SX family datasheet), and high internal performance of up to 320 MHz with 3.7 ns pin-to-pin clock-to-out, 0.1 ns input setup, and 0.25 ns clock skew. The SX family supports 66 MHz PCI designs in a single chip. Architecturally, the device uses a 0.35 um CMOS anti-fuse process with a sea-of-modules fabric of C-cells and R-cells, delivering gate densities suited to glue logic integration, bus interfacing, and control-plane logic. Because configuration is stored in the anti-fuse fabric, no external configuration PROM is required, reducing BOM cost and improving system-level security against bitstream extraction. Typical applications include industrial control systems, aerospace and defense logic integration, communications line cards, and PCI-based interface designs requiring deterministic single-chip integration at power-up. Design consideration: anti-fuse devices are one-time programmable - verify the design fully in simulation and, ideally, in the SX-A or RTAX family equivalents before committing hardware; prototype iterations require new devices.

It operates from dual supply rails of 3.0V to 3.6V and 4.75V to 5.25V with a -1 speed grade supporting up to 280 MHz toggle frequency. An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a fabric of configurable logic blocks (CLBs), logic array blocks (LABs), and programmable interconnects that the designer wires together after manufacturing. Within the programmable logic hierarchy, the A54SX16 sits in the antifuse-FPGA branch: FPGA -> programmable logic device -> digital logic IC -> semiconductor. Antifuse FPGAs such as the SX family are one-time programmable, meaning their configuration is permanent and non-volatile, which improves resistance to configuration readback and radiation-induced upset compared with SRAM FPGAs. Key features include the sea-of-modules architecture that shortens design time and lowers power consumption, 1452 logic array blocks / configurable logic blocks, 0.35 um process technology, and dual-voltage operation that simplifies integration into mixed 3.3V/5V legacy systems. The -1 speed grade is the standard performance bin of the SX family, while faster -2 and radiation-tolerant SX-A/SX-S variants exist in the same architecture. The SX architecture uses a deterministic routing fabric built around C-cells and R-cells, giving predictable pin-to-pin delays that simplify timing closure in glue logic, bus interfacing, and state-machine designs. Because configuration is stored in antifuse elements rather than an external boot flash, the device is instantly active at power-up with no configuration time. Typical applications include industrial control glue logic, legacy 5V/3.3V bus bridging, telecommunications line-card control, and defense/aerospace upgrades where one-time programmability and instant-on behavior matter. The 208-pin PQFP with 0.5 mm lead pitch suits standard surface-mount assembly. Design consideration: verify both supply domains at the PCB level, because the SX family requires separate core and I/O rails; inadequate decoupling on the 5V rail is a common pitfall in retrofits.

Architecturally, the SX family uses a sea-of-modules structure with dedicated registers, high module utilization efficiency, and deterministic routing, which yields predictable timing and low power compared to SRAM FPGAs. Because the configuration is stored in antifuse elements rather than an external configuration device, the design cannot be read back, providing strong intellectual-property protection. Typical applications include industrial control and automation, aerospace and defense subsystems, communications and networking glue logic, and bridge/PCI interface integration where single-chip consolidation of multiple devices reduces cost, board area, and power. Design consideration: antifuse programming is irreversible, so verify the full design in simulation and, when possible, use the corresponding Programmer/debug flow before committing a device.

It operates from a dual supply of 3V to 3.6V (core) and 4.75V to 5.25V (I/O), with a commercial operating temperature range of 0C to +70C. An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a fabric of configurable logic blocks and programmable interconnects that the designer wires together after manufacturing. Within the programmable-logic hierarchy, the device sits under FPGA -> programmable logic IC -> application-specific digital IC. The SX family uses antifuse programmability, meaning connections are permanently set at programming time - configuration is stored in the silicon itself, starts up instantly with no external boot memory, and is inherently resistant to configuration readback. Key features of the A54SX16-1TQG176 include its sea-of-modules architecture for high logic utilization, the -1 speed grade suited to standard-performance timing requirements, and 5V-tolerant I/O operation enabled by the 5V supply option. The antifuse fabric delivers low interconnect delay and low static power consumption compared with SRAM-based alternatives of the same era, making it attractive for glue logic consolidation, bus bridging, and control-path integration. Architecturally, the SX family is built on a 0.35 um-class process (per family data) with a module-based fabric that simplifies timing closure and design migration. Because the routing is deterministic and the device is one-time programmable, designers often use it in cost-sensitive systems where a modern SRAM FPGA would be over-specified and higher cost. Typical applications include industrial control logic, communication interface bridging, legacy design continuation, and single-chip integration of multiple 74-series-style functions. The 147 I/O count supports wide parallel buses common in these systems. Design consideration: the device is one-time programmable, so any logic change requires a new physical part - verify the bitstream thoroughly before committing to programming and assembly. Also observe the two-rail power sequencing guidance in the manufacturer datasheet.

A field-programmable gate array (FPGA) is an integrated circuit that implements user-defined digital logic through a programmable interconnect fabric and configurable logic blocks. Within the programmable logic hierarchy, the SX family sits in the one-time-programmable (OTP) antifuse FPGA class: the architecture is fixed permanently at programming time, offering inherent resistance to configuration readback attacks, no external boot configuration memory requirement, and instant-on operation. The SX family's sea-of-modules architecture delivers high routing efficiency and performance for its generation, integrating many functions into a single low-cost chip.

The speed grade is -1, the slowest commercial grade in the family, suiting cost-driven designs rather than maximum-frequency pipelines. Logic capacity is implemented in Actel's module-based fabric, which yields high effective gate utilization compared with SRAM FPGAs of the same era. Technically, the SX family uses a 0.35um antifuse process with a sea-of-modules architecture in which logic modules are surrounded by abundant routing tracks, simplifying place-and-route and shortening design cycles. Because configuration is stored in antifuses rather than SRAM cells, the device requires no configuration PROM and is immune to configuration upset from radiation-induced bit flips in the configuration memory - a classic reason for selecting Actel parts in aerospace-adjacent and high-reliability industrial designs. Typical applications include industrial control and automation glue logic, legacy 5V bus interface bridging, communication equipment control planes, and defense/hi-rel system support logic where OTP security and instant-on boot matter. Design consideration: budget static and dynamic power carefully, as antifuse FPGAs dissipate standby power on dual rails; and verify the -1 speed grade timing in Libero/Microchip design software before committing the pinout.

An antifuse FPGA is a field-programmable gate array whose interconnect elements are open circuits that are permanently programmed to become low-resistance connections. Unlike SRAM-based FPGAs from Xilinx or Altera, an antifuse device is one-time programmable: its configuration is non-volatile, immune to configuration readback attacks, requires no external configuration PROM, and starts functioning within microseconds of power-up. Within the power management hierarchy of programmable logic, the SX family sits as a high-speed, low-power, secure fabric option for fixed-function designs. Key features include a sea-of-modules architecture that yields deterministic sub-nanosecond routing delays, 0.35 um CMOS antifuse technology for low static power, and dual-voltage 3.3 V/5 V I/O operation enabling direct interfacing with legacy 5 V TTL systems. The 280 MHz toggle capability supports performance-intensive glueless integration of high-speed state machines and datapaths. Technically, the SX architecture replaces the segment-and-switchbox routing of SRAM FPGAs with a sea-of-modules structure, so interconnect delay scales predictably with fanout rather than with routing congestion. The A54SX16 provides 16,000 equivalent gates (nominal 24,000 gates on some grades per Microsemi USA listings) implemented in configurable logic modules, supporting counter, arithmetic, and control functions at speeds unattainable by earlier Actel families. Typical applications include industrial control and automation, aerospace and defense logic replacement, 5 V legacy bus interfacing, telecommunications line cards, and single-chip ASIC prototyping where non-volatile instant-on operation is mandatory. Design consideration: antifuse programming is permanent, so verify the design fully in simulation and, ideally, on an SX-A debug device before programming production parts; also plan the 3.3 V core and 5 V I/O rail sequencing on the PCB.
