A54SX16A-1TQG144M - 16K Gate 2.5V FPGA 144-TQFP | Microchip
The Microchip Technology (Microsemi/Actel) A54SX16A-1TQG144M is an SX-A family antifuse FPGA offering 16,000 raw gates (up to 24,000 system gates), 924 logic modules, and 111 user I/O in a 144-pin TQFP surface-mount package. Fabricated on a 0.25 um process and operating from a 2.5 V core supply, it supports toggle rates up to 263 MHz with a -1 standard speed grade. A field-programmable gate array (FPGA) is an integrated circuit that engineers configure after manufacturing to implement custom digital logic. Within the programmable logic hierarchy (FPGA -> programmable logic device -> digital logic IC -> semiconductor), the A54SX16A belongs to the one-time-programmable (OTP) antifuse category, distinct from SRAM-based FPGAs from Xilinx or Altera because its configuration is stored physically in antifuse elements rather than volatile memory cells. Key features include non-volatile, radiation-tolerant-heritage antifuse interconnect that removes the need for an external configuration PROM, instantaneous power-on operation, low static power typical of antifuse architectures, and secure design IP because the programmed netlist cannot be read back. The 111 user I/O support common 3.3 V and 2.5 V interface standards for board-level connectivity. Architecturally, the SX-A family uses a sea-of-modules fabric with combinational and sequential logic modules (C-cells and R-cells) connected through a hierarchical routing structure. This yields predictable, ASIC-like timing after place-and-route, an advantage over SRAM FPGAs for gluing logic, state machines, and bus-interface functions that must meet fixed timing budgets. Typical applications include industrial control and automation, communications and networking line cards, aerospace and defense systems where configuration volatility is unacceptable, medical instrumentation, and legacy ASIC replacement or system integration of multiple discrete logic devices into one low-cost single-chip solution. Design consideration: because the device is one-time programmable, verify the design thoroughly in simulation before programming and reserve spare I/O and logic margin for late changes; the -1 speed grade and 263 MHz maximum toggle rate bound achievable clock frequencies.

A54SX16A-2PQG208 - 24K Gate Antifuse FPGA, 208-PQFP | Microchip
The Microchip Technology A54SX16A-2PQG208 is a 24,000-system-gate antifuse FPGA from the SX-A family, offering 1452 logic cells (CLBs), a toggle frequency of up to 294 MHz, and 175 user I/Os, housed in a 208-pin plastic quad flat pack (PQFP-208) package. An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a matrix of configurable logic blocks interconnected by programmable fabric, allowing designers to implement custom digital circuits after manufacturing. Within the programmable logic hierarchy, the SX-A family belongs to the one-time-programmable (OTP) antifuse category, sitting alongside SRAM-based and flash-based FPGAs as a power-management and integration solution in embedded systems. Key features include 0.22 um / 0.25 um CMOS antifuse technology for low power and high security, support for 2.5 V, 3.3 V, and 5 V I/O standards, and a speed grade of -2. Because antifuse interconnects are permanently set at programming time, the device offers non-volatile configuration with no external boot flash, low static power consumption, and strong resistance to design theft compared with SRAM FPGAs. The SX-A architecture uses a sea-of-modules fabric with C-cells and R-cells that combine combinatorial and sequential logic efficiently, achieving high utilization and fast predictable routing. Typical system speeds of approximately 100-250 MHz are attainable for common designs, with the 294 MHz figure representing the maximum toggle rate of the logic fabric. Typical applications include industrial control, military and aerospace glue logic, bus interfacing, protocol bridging, and single-chip integration of ASIC prototypes where cost, security, and low power matter more than reprogrammability. Designers should note that the device is one-time programmable: the design must be fully verified before programming, and design changes require a new device. Adequate power supply decoupling and careful I/O bank voltage planning are essential.

A54SX16A-2PQG208I - 24k-Gate Antifuse FPGA, PQFP-208 | Microchip
The Microchip Technology (Microsemi) A54SX16A-2PQG208I is an antifuse FPGA from the SX-A family providing approximately 24,000 system gates (14,520 logic cells / 1,452 CLBs), up to 175 user I/Os, and a maximum toggle frequency of 294 MHz, housed in a 208-pin plastic QFP (PQFP-208 / QFP-208) package for industrial temperature ranges. A field-programmable gate array (FPGA) is a semiconductor device containing configurable logic blocks (CLBs) and programmable interconnects that the designer wires together after manufacturing. Unlike SRAM FPGAs, the SX-A family uses antifuse programming technology: one-time programmable connections that retain configuration through power cycles, need no external configuration memory, and offer inherent resistance to bit-stream readback, making them a subcategory of non-volatile, single-chip programmable logic within the broader power/space/defense-oriented FPGA hierarchy. Key features include 1,452 CLBs of logic capacity, 175 user-input/output pins in the 208-BFQFP footprint, a 294 MHz maximum system frequency, CMOS low-power operation, and RoHS-compliant lead-free plastic packaging. The '-2' speed grade and the 'I' industrial temperature suffix distinguish this member from commercial (-C) and standard speed (-1) variants. Technically, the SX-A architecture combines a sea-of-modules logic fabric with high-speed, low-skew routing resources. The antifuse interconnect adds near-zero programming overhead to routing delay, giving deterministic timing that simplifies closure in glue-logic, bus-interface, and state-machine designs. Because configuration is permanent, designs are secure against cloning and do not require a boot PROM, reducing board cost and turn-on failure modes. Typical applications include industrial control glue logic, legacy aerospace/defense board refresh, communications bridge logic, and single-chip integration of multiple discrete ASSP/PLD functions to cut BOM cost, exactly the system-wide savings Microchip promotes for SX-A devices. A key design consideration: antifuse FPGAs are one-time programmable. Verify the design fully in simulation and, ideally, in a comparable device before committing the flight/production unit, and confirm I/O banking voltages against the SX-A family datasheet.

The -2 speed grade and the P commercial temperature suffix make this part suited to cost-sensitive high-volume designs. An antifuse FPGA is a field-programmable gate array whose interconnect is permanently programmed by blowing microscopic antifuse links at power-up configuration. Unlike SRAM-based FPGAs from Xilinx or Altera, antifuse devices such as the SX-A family need no external configuration memory, offer inherent resistance to configuration corruption, and exhibit lower static power - placing them in the broader hierarchy of programmable logic within the semiconductor and power-management system ecosystem. Key features include the sea-of-modules architecture built from R-cells (register cells) and C-cells (combinatorial cells), a 2.5V CMOS core fabricated on a 0.25um/0.22um process, operation from a nominal 2.5V supply with the documented 2.25V to 5.25V I/O supply range cited by Microchip USA, and single-chip integration that removes external boot flash. The 81 available user I/O deliver broad pinout flexibility in the compact 14x14 mm TQFP-100 body. Architecturally, the SX-A device floor is covered with a grid of logic modules virtually free of routing overhead, giving predictable timing. Cluster and direct interconnect routing minimizes delay, and the -2 speed grade supports clock rates approaching 294 MHz as reported by distributor datasheet listings, with the M automotive-style variant listed up to 313 MHz. Typical applications include glue-logic consolidation, bus interface bridging, industrial control sequencing, and aerospace/military designs that exploit the antifuse family's radiation-tolerant heritage and security advantages. Design consideration: antifuse programming is one-time and irreversible - fully verify the design in simulation before programming production devices, and budget the required ACT/Silicon Sculptor programmer access.

A field-programmable gate array (FPGA) is a type of programmable logic device that implements custom digital circuits through a fabric of configurable logic blocks (CLBs) and programmable interconnect. Unlike SRAM-based FPGAs, the SX-A family uses antifuse programmable interconnect elements, which are one-time programmable and retain their configuration permanently. This places the SX-A in the hierarchy: FPGA -> programmable logic device -> digital logic IC -> semiconductor. Key features include 24K system gates (16K typical available gates), 81 user-programmable I/O with multiple standards support, a low-cost single-chip integration path that replaces multiple glue-logic devices, and a permanently programmed antifuse architecture that provides inherent design security - the configured bitstream cannot be read back. The -2 speed grade offers high clock rates suitable for state machines, bus interfaces, and control logic. Technically, the device is built on CMOS antifuse process technology with 0.22-micron-class geometry, operating from a nominal 2.5 V core supply (2.25 V to 2.75 V range per distributor data) over a commercial temperature range of 0 C to +70 C. The TQFP-100 footprint supports reflow soldering in standard SMT assembly lines. Typical applications include industrial control glue logic, communications bridging, legacy system re-engineering, and military/aerospace program sustainment where one-time-programmable, secure configuration is valued. Design consideration: because antifuse devices are one-time-programmable, always verify the design in simulation and, ideally, on a higher-density prototype part before committing production devices to programming.

A54SX16A-2TQG100I - 24K Gate Antifuse FPGA 81 I/O | Microchip
The Microchip Technology A54SX16A-2TQG100I is a 24,000 system gate antifuse FPGA from the SX-A family, delivering 81 user I/Os and a maximum toggle rate of 294 MHz in a 100-pin TQFP (14x14 mm, TQG100) package rated for the industrial temperature range of -40C to +85C. An antifuse FPGA is a type of field-programmable gate array whose interconnects are permanently programmed at power-up by blowing on-chip antifuse links. Unlike SRAM-based FPGAs, antifuse devices are non-volatile, require no configuration PROM, offer inherent resistance to bit-stream reverse engineering, and draw no configuration power, making them a secure, low-power branch of the programmable logic taxonomy that sits alongside flash-based and SRAM-based FPGA architectures. Key features of the A54SX16A-2TQG100I include 1,452 configurable logic blocks (CLBs), a wide 2.25V to 5.25V supply voltage range supporting mixed-voltage systems, and the speed-grade -2 performance tier, which supports system toggle frequencies up to 294 MHz. The device is fabricated in CMOS, and the antifuse fabric provides deterministic interconnect delays that simplify timing closure in high-reliability designs. Architecturally, the SX-A family uses a sea-of-modules structure composed of logic modules and register cells surrounded by a horizontal and vertical routing channel mesh. The high routing capacity yields high routability and fast pin-to-pin delays. Because configuration is stored in antifuse elements rather than SRAM, the programmed design survives power cycling with zero startup latency and cannot be read back, an important security property for defense and industrial designs. Typical applications include industrial control and automation, glue-logic consolidation, bus interface bridging, secure military and avionics subsystems, and communication equipment where single-chip integration of multiple discrete functions lowers system cost. With 81 I/Os and 24K gates, this density point fits medium-complexity control and interface logic. When designing with this device, plan for one-time programmability: unlike SRAM FPGAs, the antifuse fabric cannot be reprogrammed, so exhaustively verify the design in simulation and on a reprogrammable prototyping path before committing production parts. The 2.25V to 5.25V supply window simplifies legacy 3.3V and 5V board integration.

An FPGA (Field Programmable Gate Array) is a semiconductor device containing a matrix of configurable logic blocks interconnected by programmable routing, allowing designers to implement custom digital circuits after manufacturing. Within the programmable logic hierarchy, the A54SX16A belongs to the sea-of-modules antifuse FPGA category: FPGA -> programmable logic IC -> CMOS digital IC. Microchip (formerly Microsemi, originally Actel) positions the SX-A family as a low-cost, single-chip integration platform. Key differentiating features include the 0.25 um CMOS antifuse technology, which makes configuration permanent and inherently resistant to configuration readback attacks, a single 2.5V supply (2.25V to 2.75V tolerance), speed grade -2 timing with typical combinatorial CLB delay around 1 ns, and non-volatile programming that eliminates the external boot flash and configuration bitstream required by SRAM FPGAs. The SX-A architecture arranges its 924 logic cells (1,452 CLBs) in a sea-of-modules fabric with dedicated routing resources, supporting both combinatorial and registered functions with clock frequencies approaching 294 MHz. Because the antifuse interconnect is programmed once at the factory-programmable stage or during board assembly, standby power is very low and there is no configuration uptime penalty at power-up. Typical applications include industrial control and automation glue logic consolidation, aerospace and defense designs requiring design security, telecommunications line-card support logic, and medical instrumentation control circuits. The 113 user I/O supports 2.5V and 3.3V-tolerant signaling common in these domains. Design consideration: antifuse FPGAs are one-time programmable; finalize the design and verify timing in simulation before committing devices, and budget for the programmer and programming socket during production planning.

The 20x20 mm TQFP-144 footprint with 0.5 mm pin pitch enables surface-mount assembly on standard PCB processes without the expense of fine-pitch BGA assembly. Technically, the SX-A family combines a high-performance module fabric with antifuse interconnect, delivering deterministic timing and low static power consumption. The -2 speed grade supports system toggle rates in the hundreds of MHz, sufficient for glue logic consolidation, bus bridging, state machines, and protocol interfacing in embedded systems. Typical applications include industrial control and automation, communications and networking line cards, aerospace and defense systems requiring configuration security, and legacy system life-extension where a single-chip replacement for multiple TTL/PLD devices reduces board area and cost. A key design consideration is that antifuse FPGAs are one-time programmable: exhaustively verify the design in simulation and, ideally, in a socketed or dev-board environment before committing production programming. Device-specific pin assignments must be cross-checked against the Microsemi/Microchip datasheet.

The 0.25 um process supports system speeds up to 227 MHz toggle frequency, adequate for glue logic, bus interfacing, state machines, and address decoding at moderate clock rates. Architecturally, SX-A devices place routing resources in the top two metal layers above the logic modules, optimizing silicon area and giving predictable, low-skew interconnect. Because the antifuse fabric is one-time programmable, designs are immune to configuration-stream corruption and require no configuration controller, reducing bill-of-materials count versus SRAM FPGAs. Typical applications include industrial control and automation, telecommunications line-card glue logic, aerospace and defense systems requiring non-volatile, secure programmable logic, and legacy board designs where the SX-A family remains the qualified choice. Designers should plan the pinout and one-time programming budget carefully: unlike SRAM FPGAs, an antifuse device cannot be reprogrammed after metal fuses are blown, so functional verification before programming is essential. The PQFP package requires careful PCB land-pattern design for fine 0.5 mm pitch leads.

Key features include 16K system gates of configurable logic capacity, 924 logic cells implemented as fast C-cells and S-cells, internal clock performance up to 227 MHz, and 175 flexible user I/O supporting 2.5V signaling. Because the interconnect matrix is metal-to-metal antifuse, the device exhibits low toggle-rate power consumption and inherently low jitter path delays. The PQFP-208 package provides gull-wing leads for surface-mount assembly and inspection. The SX-A architecture uses a sea-of-modules fabric with a three-tier routing structure (FastConnect, DirectConnect, and general routing), giving deterministic, short interconnect delays that simplify timing closure in state machines, glue logic, and bus interfaces. Programming is performed after assembly via ACTgen and Designer software flows with standard fuse-blow programming hardware. Typical applications include military and avionics glue logic, communication bridging, bus interface conversion, secure single-chip system integration, and industrial control where non-volatile, tamper-resistant configuration is required. Design consideration: the device is one-time programmable, so logic must be fully verified before programming; plan power and I/O budgets against the 175-I/O limit.

A54SX16A-TQG100 - 24K Gate Antifuse FPGA, 81 I/O | Microchip
The Microchip Technology (Actel/Microsemi) A54SX16A-TQG100 is a 24,000-system-gate antifuse FPGA from the SX-A family with up to 81 user-programmable I/O, 2,012 dedicated flip-flops, and a 227 MHz system performance rating, housed in a 100-pin TQFP (TQG100) package. A field programmable gate array (FPGA) is a semiconductor device containing configurable logic blocks and programmable interconnects that designers configure after manufacturing. The SX-A family belongs to the antifuse FPGA category within the broader programmable logic hierarchy (FPGA -> programmable logic device -> digital IC -> semiconductor). Unlike SRAM-based FPGAs, antifuse devices are one-time programmable, which permanently locks the configuration and makes the design immune to readback, giving inherent security and radiation-tolerant behavior advantages for aerospace and defense systems. Key features include 16,000 typical usable gates (24,000 system gates), a sea-of-modules architecture that delivers deterministic interconnect delays, 0.25 um/0.22 um CMOS process technology, and a 2.5 V core supply. The 924 configurable logic cells with dedicated flip-flops support pipelined designs at up to 227 MHz, dramatically outperforming typical SRAM FPGAs of the same era for glue logic and high-speed state machines. Architecturally, the SX-A uses Actel's sea-of-modules structure with C-cells (combinational) and R-cells (register) tiled across the die, connected through a segmented routing fabric. Because antifuse interconnects have very low on-resistance and capacitance, timing is fast and predictable, and total power consumption is substantially lower than equivalent SRAM FPGA implementations. Typical applications include aerospace and defense logic replacement, industrial control, communication bridging, medical equipment glue logic, and obsolescence-driven ASIC integration where a single-chip, non-volatile, secure FPGA is required. When designing with this device, note it is one-time programmable: functional verification in simulation (Libero IDE/Designer) must be completed before programming, and design lock-up files must be retained for future respins. Observe the 2.25 V to 5.25 V I/O supply constraints on the specified pins.

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, allowing custom digital logic without fabricating an ASIC. Within the programmable-logic hierarchy, the A54SX16A belongs to the one-time-programmable antifuse FPGA category under the broader classes of programmable logic devices and application-specific integrated circuit alternatives. Antifuse technology stores its configuration physically, offering inherent resistance to radiation-induced configuration upsets and cloning. Key features of the A54SX16A-TQG100A include 24,000 equivalent system gates with approximately 16,000 typical gates available for design implementation, 1,452 configurable logic blocks organized in the SX-A sea-of-modules architecture, and a wide supply voltage range of 2.25V to 5.25V that simplifies integration into mixed-voltage systems. The device is fabricated on a 0.25 um CMOS process and supports an operating temperature range of -40C to +125C (TA), suitable for harsh-environment and automotive-adjacent applications. Technically, the SX-A family delivers high performance through its Sea-of-Modules architecture with low routing delay, achieving a maximum toggle rate of 227 MHz while keeping static power consumption low compared to SRAM-based FPGAs. Because configuration is stored in antifuse elements, the device powers up instantly with no external configuration PROM, reducing board cost, boot time, and configuration-glitch security risks. Typical applications include industrial control and automation logic, glue logic and bus-interface integration, communication and networking control functions, and military or aerospace systems where single-chip integration, low power, and configuration security are valued. Replacing multiple discrete MSI/SSI devices with one A54SX16A reduces board area, assembly cost, and inventory. A key design consideration is that antifuse FPGAs are one-time programmable: programming errors cannot be corrected in-circuit, so thorough simulation and the vendor programming service flow must be completed before commit. Pinout flexibility at design entry should also be fixed before programming.

Fabricated on a 0.25 um CMOS process, it provides up to 2,012 dedicated flip-flops and non-volatile, single-programmable antifuse interconnect for high security and low power. An antifuse FPGA is a type of field-programmable gate array whose interconnect is permanently programmed at power-up programming time via antifuse links, unlike SRAM-based FPGAs that reload configuration from an external flash device at every boot. Because the configuration is hard-wired, antifuse FPGAs sit within the programmable logic hierarchy (FPGA -> programmable logic device -> digital IC) as a one-time-programmable, non-volatile technology favored where bitstream security, instant-on operation, and radiation robustness matter. Key features of the A54SX16A include the sea-of-modules architecture that simplifies design transfer from the older SX family, dedicated flip-flops with fast setup times, and low static power consumption typical of antifuse technology. With 24K system gates (expandable to 108,000 available system gates across the family), the device targets glue logic integration, bus bridging, state machines, and control-path functions consolidated into a single low-cost chip. The SX-A architecture uses a sea-of-modules routing fabric with a fine-grained logic cell structure, enabling high logic utilization and predictable timing. Programming is performed once using Microchip (Actel) programming hardware; the programmed antifuse network is non-volatile and highly resistant to readback, providing a built-in security advantage over SRAM FPGAs that store bitstreams externally. Typical applications include industrial control and automation boards, aerospace and defense subsystems requiring secure boot logic, communications interface bridging, and legacy design continuity for systems originally qualified around Actel SX/SX-A silicon. When designing with the A54SX16A, remember that antifuse FPGAs are one-time-programmable: exhaustively verify the design in simulation and, where possible, use the same-family SX-A development flow before committing silicon. Package speed-grade and temperature variants are not interchangeable in programming files without re-timing verification.

An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a sea of configurable logic modules and interconnect that designers program to implement custom digital circuits. Within the programmable logic hierarchy, the SX-A family sits in the one-time-programmable (OTP) antifuse FPGA class, as opposed to SRAM-based FPGAs such as Xilinx Spartan or Altera Cyclone devices. Antifuse technology permanently programs each connection at power-up configuration time, giving the device inherent configuration security and no need for an external configuration PROM. Key features include the amorphous-silicon antifuse interconnect with tungsten plug vias, a 2.25 V to 5.25 V single supply operating range, and 0.25 um / 0.22 um CMOS technology. The die uses three layers of metal with the antifuse between Metal 2 and Metal 3. This architecture delivers ASIC-like performance, very low static power, and resistance to bit-stream theft, which is why SX-A remains popular in legacy industrial and defense programs. The sea-of-modules architecture supports 924 usable logic cells organized into 1452 LABs/CLBs, with system performance up to 227 MHz. Because configuration is non-volatile and one-time, the device is immune to configuration readback attacks and eliminates boot-time configuration delays. Typical applications include industrial automation controllers, glueless bus interface and bridge logic, communication equipment control planes, and defense/aerospace legacy designs requiring configuration security. Design consideration: since the device is OTP, thoroughly verify the design through simulation (Libero SoC or legacy Actel toolchains) before programming; there is no rework path after antifuse programming.

The SX architecture uses a sea-of-modules fabric with Combinatorial Modules (CMs) and Register Modules (RMs), achieving a combinatorial CLB delay of approximately 0.8 ns. Because routing is antifase-based, the device is non-volatile, secure against readback, and immune to configuration SEU at power-up, which historically made SX FPGAs popular in aerospace, industrial, and communications platforms. Typical applications include 66 MHz PCI bus interface logic, industrial control and automation glue logic consolidation, telecommunications line-card logic, and legacy military/avionics boards requiring non-volatile programmable logic. When designing with this device, budget the 3.3V core supply and account for the PQFP 28x28 mm footprint and 0.5 mm lead pitch in PCB layout; verify final timing with Microchip (Actel) Designer software after place-and-route.

Architecturally, the A54SX16P uses a sea-of-modules fabric of C-cells and S-modules that yields predictable, routing-independent timing. The 'P' suffix family supports 3.3V core operation with 5.0V-tolerant inputs, easing mixed-voltage system integration and legacy 5V bus interfacing. The -1 speed grade balances performance with lower static power versus -2 parts. Typical applications include industrial automation controllers, PCI bus interfacing, communications and wireless infrastructure, test and measurement equipment, and military/aerospace subsystems where one-time-programmable antifuse security matters. Design consideration: verify timing closure in Libero SoC at worst-case -1 grade conditions rather than typical, since antifuse devices cannot be reprogrammed if speed grades are marginal in-system.
