A54SX32-PQG208I - SX FPGA 48K Gates 174 I/O | Microchip
The Microchip Technology (Microsemi/Actel) A54SX32-PQG208I is a member of the SX family of anti-fuse FPGAs offering 32,000 logic gates (48K system gates), 1800 logic modules, 174 user I/Os, and system performance up to 240 MHz, housed in a 208-pin Plastic Quad Flat Pack (PQG208/BFQFP) with industrial temperature rating of -40C to +85C. It operates from a 3.3V/5V supply on 0.35 um CMOS technology. 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 A54SX32 sits at the device level under FPGA -> programmable logic -> digital logic IC. The SX family uses a sea-of-modules architecture built on a patented antifuse interconnect, which delivers ASIC-like routability and performance with no configuration storage element required. Key features include one-time-programmable antifuse technology that eliminates the need for external boot flash and removes configuration-bitstream security concerns, sub-10 ns deterministic interconnect delays, 174 user-input/output pins on the 208-pin QFP body, and low static power consumption typical of antifuse CMOS fabric. Technically, the device integrates combinational and sequential logic modules (the 1800-cell array) with dedicated clock resources, achieving deterministic, delay-predictable routing that SRAM FPGAs of the era could not match. The antifuse elements add near-zero capacitance to the routing network, which is the primary reason for the 240 MHz toggle capability at 0.35 um geometry. Typical applications include industrial control and automation logic, glueless bus interfacing and bridge logic, telecommunications and data-communication line-card control, and military/avionic systems where instant-on and configuration-security properties of antifuse technology are valued. A key design consideration is that antifuse FPGAs are one-time programmable: any functional change requires a new device, so reserve engineering margin in I/O count and module utilization before committing the design.

A54SX32-PQG208M - SX FPGA 32K Gates 208-QFP | Microchip
The Microchip Technology (Actel/Microsemi) A54SX32-PQG208M is an SX-family antifuse FPGA with 32K system gates (2880 CLBs) and 174 user I/Os, housed in a 208-terminal PQFP (208-BFQFP) surface-mount package with a 0.5 mm terminal pitch. An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a matrix of configurable logic blocks (CLBs) interconnected by programmable fabric, allowing designers to implement custom digital logic after manufacturing. The Actel SX family belongs to the one-time-programmable (OTP) antifuse class of FPGAs, positioned within the broader programmable logic hierarchy: FPGA -> programmable logic IC -> CMOS digital IC. Antifuse technology stores configuration physically, giving it inherently high resistance to configuration upset compared with SRAM-based FPGAs. Key features of the A54SX32 include a sea-of-modules architecture that delivers very high routing efficiency and performance per gate, a maximum toggle rate of approximately 280 MHz, and a supply voltage range of 3.0 V to 3.6 V (nominal 3.3 V) with support for 5 V-tolerant operation modes. The sea-of-modules topology simplifies timing closure because every module sits within short routing reach, enabling dramatic reductions in design time, power consumption, and time to market for performance-intensive applications. Technically, the device provides 2880 combinational and sequential capability modules organized as a dense mesh. Because configuration is stored in antifuse elements rather than volatile SRAM, no external configuration PROM is required, reducing BOM cost and board space and improving system security since the bitstream is not readable. The PQG208 commercial temperature variant supports 0 C to +70 C ambient operation. Typical applications include industrial control and automation logic, communications and networking glue logic, test and measurement instrumentation, and mil/aero-adjacent ground equipment where one-time programmability and design security are valued. A key design consideration: antifuse FPGAs are OTP - an incorrect programming run consumes a device, so reserve spare I/Os and gate margin, and use Microchip Libero/Designer tool timing reports before committing to programming.

This eliminates configuration time and configuration readback security risks common to SRAM FPGAs. Architecturally, the SX family combines C-cells (combinational) and R-cells (register) in a sea-of-modules array, delivering gate-level performance approaching ASIC-like timing predictability. The 0.35 um-class process yields high toggle rates with low interconnect delay variation, making static timing analysis straightforward. Typical applications include industrial control, communications and networking glue logic, avionics and defense embedded controllers, and ASIC prototype translation, where instant-on behavior and design security matter.

An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a matrix of configurable logic blocks (CLBs) interconnected by programmable interconnects, allowing designers to implement custom digital logic after manufacturing. Within the programmable logic hierarchy, the A54SX32A sits at the mid-density tier of the SX-A antifuse family, above the SX08/SX16 devices and below the SX72. Antifuse FPGAs are one-time programmable (OTP): their configuration is permanently set at programming time, giving inherent resistance to bit-flip configuration corruption and no need for an external configuration flash. Key features include a 2.5V core supply, 0.25 um CMOS process technology, a -1 speed grade supporting toggle rates up to 278 MHz, and industrial temperature operation signified by the I suffix. The 249 available I/O provide substantial interface capability for glue logic consolidation, bus bridging, and control-plane designs. Technically, the SX-A architecture uses a sea-of-modules fabric with combinational and sequential cells; the 2880 CLB/cell count maps to approximately 48,000 system gates. Because the device is OTP antifuse, designers verify logic thoroughly in simulation before programming, since the bitstream cannot be re-flashed in the field. Typical applications include industrial control and automation, telecommunications line cards, aerospace and defense systems where configuration security matters, and legacy system sustenance where the SX-A family remains the qualified solution. Design consideration: plan power distribution for a single 2.5V supply domain and account for the one-time-programmable nature by reserving spare logic and I/O in your design budget.

Key features include 48K system gates of antifuse-based programmable logic, up to 249 user-programmable I/Os in the 329-BGA package, and a 278 MHz toggle/system frequency enabled by the 0.25 um process. The 2.5V core supply keeps dynamic power low, and the one-time-programmable (OTP) antifuse architecture inherently resists configuration readback, providing design security advantages plus immunity to configuration-upset issues in harsh environments. Technically, the SX-A architecture uses a fine-grained sea-of-modules structure with combinational and sequential logic modules, enabling efficient synthesis of state machines, glue logic, bus interfaces, and data-path functions. The -1 speed grade balances performance and cost, and the M suffix denotes a specific shipping media variant per Microchip ordering conventions. Typical applications include military and aerospace systems requiring instant-on, secure configuration, industrial control backplanes, communications line-card glue logic, and obsolescence mitigation for legacy Actel/Microsemi designs still in field service. Design consideration: because the device is one-time-programmable, thoroughly verify the design in simulation and, where feasible, prototype in an SRAM-based device before committing to antifuse programming.

A54SX32A-1FGG256 - SX-A FPGA, 48K Gates, 256-FBGA | Microchip
The Microchip Technology (formerly Microsemi/Microsemi formerly Actel) A54SX32A-1FGG256 is an SX-A family antifuse FPGA offering 48,000 system gates (32,000 typical gates) with 2880 configurable logic blocks (CLBs), 203 user I/O, and a maximum clock frequency of 278 MHz, housed in a 256-ball Fine-Pitch Ball Grid Array (FBGA) package. A field-programmable gate array (FPGA) is a semiconductor device containing a matrix of configurable logic blocks interconnected by programmable fabric, allowing designers to implement custom digital circuits after manufacturing. The SX-A family sits in the FPGA hierarchy as a one-time-programmable (antifuse) device, part of the broader programmable logic category alongside CPLDs and flash-based FPGAs. Antifuse technology means the configuration is permanent, inherently secure, and immune to configuration-readback attacks, with no external configuration PROM required at power-up. Key features of the A54SX32A-1FGG256 include a 0.25 um CMOS process, a 2.5V core supply, and a combinatorial CLB delay as low as 1.1 ns, delivering fast, deterministic single-chip logic integration. With 1800 logic cells, the device suits mid-density glue logic, bus interface, and control-path designs. The 203 available I/O support common 2.5V and 3.3V signaling environments used in industrial and embedded systems. Architecturally, the SX-A fabric uses a sea-of-modules structure with combinational and sequential modules, enabling efficient mapping of wide decoders, state machines, and datapath functions. Because configuration is stored in antifuse elements rather than SRAM cells, there is no configuration time at power-up, a design advantage over SRAM FPGAs, and resulting designs are resistant to bitstream cloning. Typical applications include industrial control and automation, communications and networking line cards, avionics and defense systems requiring configuration security, and legacy ASIC/ASSP bridging where a permanent, low-power single-chip logic solution is preferred. A key design consideration: the 2.5V core and fixed antifuse routing mean the design must be fully frozen before commit; simulation and timing verification should be completed prior to programming, since a programmed device cannot be erased or reprogrammed.

An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a fabric of programmable logic blocks and interconnects that designers configure after manufacturing. Within the programmable-logic hierarchy - FPGA -> programmable logic device -> digital IC - antifuse FPGAs like the SX-A are one-time-programmable (OTP): configuration is permanently written, giving inherent resistance to configuration readback attacks and no need for an external configuration flash, which improves system reliability and security compared to SRAM FPGAs. Key features include the sea-of-modules architecture built from two logic module types: the C-cell (combinatorial) and R-cell (register), providing essentially lossless floorplan area utilization. The -1 speed grade balances performance and cost, the 256-FPBGA footprint supports high-density surface-mount assembly, and the wide 2.25V to 5.25V supply tolerance plus military-grade temperature rating make it suitable for harsh environments. RoHS3 compliance (the M suffix denotes moisture-sensitivity/lead-free flow per distributor listings) supports modern assembly processes. Architecturally, the SX-A covers the entire die with a grid of logic modules and routing, so virtually no chip area is lost to interconnect. The 32K-gate-class A54SX32A die (marketed at 48K system gates) integrates multiple glue-logic, interface, and control functions into a single low-cost chip, replacing multi-chip PAL/GAL/ASIC solutions and reducing board area, power, and BOM cost. Typical applications include aerospace and defense control logic, industrial automation controllers, communications interface bridging, and test equipment, where one-time programmability, instant-on startup, and tamper resistance matter more than reprogrammability. Design consideration: because SX-A devices are OTP, verify your design thoroughly in simulation (Libero SoC / Designer flow) before programming; there is no design iteration on the same silicon, so account for the approximately 20-week manufacturer lead time in your procurement plan.

An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a fabric of programmable logic blocks and interconnects that designers configure after manufacturing. Within the programmable logic hierarchy, the A54SX32A belongs to the one-time-programmable (OTP) antifuse class, positioned under FPGAs, programmable logic ICs, and digital semiconductors. Antifuse technology stores its configuration physically, so it retains programming permanently, powers up instantly, and is inherently resistant to configuration readback. Key features of the A54SX32A-1FGG484 include 32K gates of SX-A fabric built on a 0.25 micron CMOS process, the -1 standard speed grade, and 249 user-available I/O on the 484-ball fine-pitch BGA. The 2.5 V supply keeps dynamic power low, while the antifuse architecture eliminates configuration PROMs and boot time entirely. Technically, the SX-A architecture uses a sea-of-modules fabric with combinational and sequential cells connected by antifuse-programmed routing. Because the routing is programmed once, signal paths exhibit low, deterministic impedance, supporting the 278 MHz toggle-rate capability specified for the family. The part is lead free per distributor data (PCB Electronics lists it as LEAD FREE). Typical applications include glue-logic integration, bus interfacing, industrial control, telecommunications line-card functions, and military/aerospace designs that value the configuration security and instant-on behavior of antifuse FPGAs. A key design consideration: antifuse devices are one-time programmable, so debugging requires careful up-front simulation; prototype on a slower-speed or larger-density same-family device before committing the -1 speed grade.

A54SX32A-1PQG208I - SX-A FPGA 48K Gates 208-PQFP | Microchip
The Microchip Technology (formerly Microsemi/Actel) A54SX32A-1PQG208I is an antifuse FPGA from the SX-A family delivering 32K gates (48K system gates) with 1800 logic cells, up to 278 MHz system performance, and a 0.25 um process, housed in a 208-pin PQFP (QG) package rated for the industrial temperature range. An FPGA (Field-Programmable Gate Array) is a semiconductor device that implements digital logic through programmable interconnect and configurable logic blocks (CLBs), sitting above standard logic ICs and below ASICs in the programmable-logic hierarchy. The SX-A family uses a one-time-programmable antifuse architecture, which means the configuration is hard-wired at programming time rather than loaded from an external configuration memory at every power-up, giving inherent immunity to configuration readback and radiation-induced configuration upset. Key features include 2880 CLBs, 174 user I/O pins, 2.5V core operation, and a -1 speed grade supporting toggle rates up to 278 MHz. The antifuse fabric provides low on-resistance interconnect and deterministic routing delays, while total static power is far lower than SRAM FPGAs of similar density, making the family attractive for power-sensitive, high-reliability designs. Technically, the SX-A architecture combines sea-of-modules logic with a three-level metal routing fabric on a 0.25 um CMOS process. The D-module (combinational) and R-module (register-capable) cells give an efficient mix for both datapath and control logic. Because the antifuse is programmed once, design changes require a new device - a deliberate trade of flexibility for security, cost, and reliability. Typical applications include industrial control and automation glue logic, communications interface bridging, aerospace and defense systems that benefit from configuration immunity, and medical equipment requiring stable single-chip logic integration. Design consideration: the 2.5V core requires a dedicated supply rail and correct power sequencing relative to I/O banks; plan the 208-pin PQFP land pattern and thermal relief early since the package is not drop-in compatible with other footprints.
