A54SX32-1BG329 - SX FPGA 48K Gates 329-BGA | Microchip
The Microchip Technology (Actel) A54SX32-1BG329 is an SX-family antifuse FPGA offering 32K gates (48,000 system gates) with 1,800 logic cells, up to 280 MHz system performance, and 249 user I/Os in a 329-ball PBGA (329-BBGA) package. An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a fabric of configurable logic blocks and interconnects that designers program after manufacturing. The SX family sits in the one-time-programmable (OTP) antifuse FPGA hierarchy, below the radiation-tolerant RTAX series and alongside the higher-density SX-A family, and is manufactured on a 0.35 um CMOS process. Antifuse FPGAs are favored where configuration volatility, instantaneous boot-up, and high resistance to radiation-induced configuration upsets matter more than in-field reprogrammability. Key features of the A54SX32-1BG329 include a sea-of-modules architecture that simplifies design capture and timing closure, dual supply operation of 3.3V core and 5V-tolerant I/O capability, and deterministic performance of up to 280 MHz in system-level benchmarks. The commercial-grade (no I suffix) operating range and 329-ball BGA with 1.27 mm ball pitch provide high I/O density for bus-intensive designs. Technical depth: the SX family uses the Actel combinational-logic module (CLM) fabric with a sea-of-modules routing structure, delivering gate utilization and performance close to masked gate arrays. Because programming is via metal-to-metal antifuse links, configuration data is fixed at power-up with no external boot ROM or configuration flash required, reducing BOM cost and improving security. Typical applications include industrial control, communications and networking line cards, test and measurement instrumentation, aerospace and defense sub-systems (where SX devices later spawned the RTAX rad-hard derivatives), and glueless bus-bridging logic requiring 249 I/Os. Design consideration: antifuse OTP devices cannot be reprogrammed, so thorough simulation and iteration on engineering samples are essential before committing programming current to production units.

A54SX32-1BG329I - 32K Gate SX FPGA, 249 I/O, 329-BGA | Microchip
The Microchip Technology A54SX32-1BG329I is a 32,000-system-gate Actel SX-family FPGA with 2880 logic modules, up to 249 user I/O, and a -1 speed grade, housed in a 329-ball thermally enhanced BGA (329-BBGA) package rated for the industrial temperature range of -40C to +85C. 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 using a hardware description language such as VHDL or Verilog. Within the programmable-logic hierarchy (FPGA -> programmable logic device -> digital IC -> semiconductor), the SX family occupies the high-performance antifuse-based segment, offering non-volatile, one-time-programmable configuration with very low power. Key features include the sea-of-modules architecture built from C-cells and R-cells that delivers gate efficiencies and performance levels beyond typical SRAM FPGAs of its generation, up to 280 MHz system performance, 249 available user I/O with multiple I/O standards, and antifuse interconnect that is inherently non-volatile, resistant to configuration disturbance, and requires no configuration PROM or boot time. Technically, the SX architecture organizes logic into clusters connected through hierarchical routing, enabling predictable timing for performance-intensive designs such as bus bridging, protocol engines, and high-speed data path functions. The one-time-programmable antifuse process also removes the static current draw associated with SRAM configuration cells, reducing total power consumption in dense designs. Typical applications include industrial automation controllers, communications and networking line cards, aerospace and defense data handling, and test-and-measurement instrumentation where a non-volatile, secure, high-performance FPGA fabric is required. A key design consideration is that antifuse FPGAs cannot be reprogrammed: design changes require a new device, so thorough simulation and timing closure are essential before programming.

A54SX32-1BGG329 - 32K-Gate FPGA, 280MHz, 329-BGA | Microchip
The Microchip Technology A54SX32-1BGG329 is a 32,000-gate CMOS field programmable gate array (FPGA) from the Actel SX family, delivering 2880 logic cells, up to 249 user I/O, and a maximum clock frequency of 280 MHz, housed in a 329-ball PBGA (BGG329) package with a 1.27 mm ball pitch. An FPGA is a semiconductor device containing a matrix of configurable logic blocks (CLBs) and programmable interconnects that designers configure in the field, after manufacturing, to implement custom digital logic. Within the programmable logic hierarchy - FPGA -> programmable logic device -> digital IC -> semiconductor - the SX family occupies the high-performance, one-time-programmable (OTP) antifuse segment, distinguished from SRAM FPGAs by its non-volatile, instantly-on configuration and inherent resistance to configuration corruption. Key features include the sea-of-modules architecture that yields deterministic, ASIC-like timing; 2880 configurable logic modules (CLBs) suitable for glue logic, bus bridging, and control-path functions; 249 user-input/output pins that support wide parallel buses; and operation at up to 280 MHz system clock, among the fastest of its generation. The antifuse interconnect technology eliminates configuration boot time, reduces power consumption versus SRAM-based parts, and improves design security because no configuration bitstream is stored externally. Technically, the SX family uses a 0.35 um-class CMOS process with a continuous grid of C-cells (combinational logic) and R-cells (sequential logic) connected through a segmented routing fabric. Unlike SRAM FPGAs, routing delays are predictable after place-and-route, simplifying timing closure for performance-intensive applications. The device supports mixed 3.3V/5V I/O operation per the SX family datasheet, easing interfacing with legacy TTL-level systems. Typical applications include industrial automation controllers, communications and networking line cards, avionics and military legacy-system sustainment, test and measurement equipment, and high-speed bus interface bridge logic where instant-on, high-reliability programmable logic is required. A key design consideration is that antifuse FPGAs are one-time programmable: the design must be fully verified before programming, since a functional change requires a new physical device. Plan JTAG/Secret programming access and boundary-scan test strategy early.

An FPGA (Field-Programmable Gate Array) is a semiconductor device containing configurable logic blocks and interconnects that the designer programs after manufacturing. The SX family belongs to the one-time-programmable antifuse FPGA class, which sits within the broader programmable logic hierarchy: FPGA -> programmable logic IC -> programmable semiconductor. Unlike SRAM FPGAs, antifuse devices retain their configuration permanently, are inherently resistant to configuration readback, and require no external boot configuration memory. Key features include the sea-of-modules architecture that delivers high-performance, high-integration implementation with lower design cost and power consumption than SRAM-based alternatives, 1800 logic cells (2880 configurable logic modules), dual 3.3V/5V I/O compatibility, and the -1 speed grade supporting up to 280 MHz. The 329-ball BGA provides high I/O density for bus-intensive designs while remaining reworkable with standard BGA assembly processes. Technically, the SX family is fabricated on a 0.35 um CMOS process optimized for predictable timing. Because routing is fixed by the antifuse fabric, timing after programming closely matches pre-programming simulation, which simplifies sign-off in high-reliability systems. The device is programmed once using Microchip (formerly Actel/Microsemi) programmer hardware and design tools, then behaves as an ASIC-like fixed-logic device. Typical applications include industrial control and automation, communication and networking interface logic, glueless bus bridging, military/aerospace heritage systems requiring configuration security, and test equipment where deterministic timing is essential. Design consideration: antifuse FPGAs are one-time programmable - verify the design fully in simulation and timing analysis before programming, since a design change requires a new device.

An FPGA (Field-Programmable Gate Array) is a semiconductor device containing programmable logic blocks and interconnects that the designer configures after manufacturing, sitting within the broader hierarchy of programmable logic below system-on-chip devices but above simple SPLDs and CPLDs. The Actel SX family uses a sea-of-modules architecture with antifuse interconnect, meaning the configuration is hard-wired at programming time rather than stored in volatile SRAM, so the device powers up instantly with no external configuration ROM and offers inherent resistance to configuration upset. Key features include 32,000 typical gates (up to 48,000 system gates), 1800 cells organized as 2880 C-cells and R-cells in the sea-of-modules fabric, dual-voltage operation supporting 3.0V to 3.6V core and 4.75V to 5.25V I/O, and 0.35 micron CMOS process technology supporting clock rates up to 240 MHz. The 174 user-I/O pins support both 3.3V and 5V signaling, easing mixed-voltage legacy system integration. Technically, the SX architecture separates dedicated clock resources and high-speed routing from the module fabric, enabling predictable, ASIC-like timing. Because antifuse programming is one-time, the device suits production designs where volatility, security against bitstream theft, and instant-on behavior matter more than in-field reconfigurability. Typical applications include industrial control, military and aerospace interfaces, communications line cards, test equipment, and glueless bridge logic between 5V legacy systems and 3.3V subsystems. The commercial temperature range (-part suffix 1C, 0C to +70C) targets cost-sensitive industrial and commercial deployments. Design consideration: antifuse FPGAs cannot be reprogrammed; reserve adequate I/O and gate margin (20-30%) before committing the design, since design changes require a new device.

A54SX32-1PQG208 - 32K Gate SX FPGA, 208-PQFP | Microchip
The Microchip Technology (Microsemi/Actel) A54SX32-1PQG208 is an SX-family antifuse FPGA with 32,000 typical system gates, 1,800 logic modules, up to 280 MHz system performance, 174 user I/Os, and a 208-pin plastic quad flat pack (208-PQFP / 208-BFQFP) surface-mount package operating from a 3.3V/5V supply mix. An antifuse FPGA is a one-time-programmable (OTP) field-programmable gate array in which each programmable interconnect point is an open antifuse that is permanently shorted during programming. Unlike SRAM FPGAs, antifuse devices retain their configuration in silicon, require no configuration PROM, boot instantly at power-up, and are inherently resistant to configuration corruption - traits that placed the Actel SX family in a hierarchy running FPGA -> antifuse FPGA -> one-time-programmable programmable logic -> programmable semiconductor. Key features include the sea-of-modules architecture built from Combinatorial Modules (CMs) and Register Modules (RMs), which delivers gate utilization and routing efficiency well ahead of SRAM architectures of the same era; a 0.35 um CMOS process enabling internal toggle rates up to roughly 280 MHz; and a wide operating family spanning 6K to 60K system gates with I/O standards supporting 3.3V and 5V signaling. Technically, the SX architecture clusters CM/RM pairs into clusters and superclusters, keeping critical interconnect local and short. This is why the family achieves ASIC-like speed and deterministic timing without the configuration-load penalty of SRAM parts, while consuming low static power. Design entry uses the Actel/Microchip Libero design flow with VHDL or Verilog synthesis; programming is performed once via dedicated programming equipment because antifuses cannot be reprogrammed. Typical applications include glue logic and bus-interface consolidation in industrial control, aerospace and defense boards requiring instant-on, boot-free configuration, telecommunications line cards, and motor/automation controllers where design security matters. The PQFP-208 package suits reflow-soldered, moderately pin-dense boards. Design consideration: because the device is one-time-programmable, simulate thoroughly and freeze the design before committing silicon; a design change requires a new device, so plan procurement accordingly.

The -1 speed grade and I suffix denote a standard speed grade with industrial qualification. An antifuse FPGA is a type of field-programmable gate array whose interconnects are permanently programmed at power-up programming time by antifuse elements, in contrast to SRAM-based FPGAs that require an external configuration device. Within the programmable logic hierarchy, the A54SX32 belongs to the broader class of programmable logic devices (PLDs), positioned above CPLDs in density and below radiation-tolerant families such as RTAX in the Microchip portfolio. The sea-of-modules architecture of the SX family delivers ASIC-like performance and integration levels, simplifying design time and reducing system cost and power consumption. Key features include 0.35 um CMOS antifuse technology, support for both 3.3V and 5V I/O operating environments, a 2,880-module sea-of-modules fabric, and combinational cell delays in the sub-nanosecond class that enable 280 MHz system performance. Because configuration data is stored in antifuses rather than volatile memory, the device is live at power-up with no boot time and inherently resists bitstream readback, a security advantage over SRAM FPGAs. The SX architecture organizes logic into C-cells (combinational) and R-cells (sequential/register) with dedicated fast carry chains and a hierarchical routing structure, allowing wide decoding functions and high-speed state machines. Typical applications include industrial control, embedded glue logic replacement, bus interfacing, telecommunications line cards, test equipment, and military/industrial systems requiring non-volatile, instant-on programmable logic. Design considerations: the 208-pin QFP requires careful PCB land-pattern design with attention to power/ground pin pairs; antifuse devices are one-time programmable, so functional verification in the Libero/Designer flow is essential before programming. Estimated power should be calculated with the manufacturer power calculator using design toggle rates.

An FPGA (Field-Programmable Gate Array) is a reconfigurable logic device that sits above fixed-function ASICs and below general-purpose processors in the system hierarchy, allowing designers to implement custom digital logic, state machines, bus interfaces and glue logic. The Actel SX family on which this device is based uses a sea-of-modules antifuse architecture, meaning its interconnect is programmed one-time at programming time and retains the configuration permanently, unlike SRAM FPGAs that require a configuration PROM and lose configuration on power-down. Key features of the A54SX32-1PQG208M include a one-time-programmable antifuse fabric that removes the need for external boot memory, a compact logic module based on a multiplexer-driven cell optimized for high-speed decode and mux functions, 5V/3.3V dual-supply compatibility, and a fine-pitch 208-terminal PQFP footprint with 0.5 mm lead pitch. The device is fabricated on a 0.35 um CMOS process, which keeps static power low and makes the family well-suited to cost- and power-sensitive embedded systems. Architecturally, the sea-of-modules organization of the SX family delivers ASIC-like routing density and predictable timing, with each logic module connected through a programmed antifuse interconnect matrix. Because configuration is stored in the silicon itself, the part powers up instantly with no configuration time and offers inherent resistance to configuration corruption from radiation or power glitches, an attribute that made SX devices popular in industrial and aerospace heritage designs. Typical applications include industrial control and automation glue logic, bus bridging and interface conversion, telecom line-card control logic, and legacy-system sustainment where the original board footprint must be preserved without redesign. When designing with this device, plan for one-time programmability: verify the design thoroughly in simulation and, where possible, use the same family in a larger die for prototyping, since errors cannot be reprogrammed in the field.

Within the programmable logic hierarchy, the device sits as a one-time-programmable (OTP) fabric under the broader category of programmable logic devices, positioned by Microchip alongside its ProASIC and RTAX families. The SX family uses a sea-of-modules architecture combining C-cells (combinational logic) and R-cells (sequential logic) to deliver ASIC-like performance and integration levels not achieved by SRAM FPGAs of its generation. Key features include the antifuse interconnect technology, which provides non-volatile, secure, radiation-tolerant-friendly configuration with no external boot PROM; 3.3V core operation with 5V-tolerant I/O; and deterministic sub-nanosecond interconnect delays that simplify timing closure. The 280 MHz maximum toggle capability supports performance-intensive applications such as high-speed bus interfacing and protocol bridging. The sea-of-modules architecture eliminates the hierarchical routing delays typical of SRAM FPGAs, enabling predictable, short gate-to-gate delays. Because configuration is stored in antifuse elements, the device draws no configuration current at power-up and offers high resistance to design cloning compared with reprogrammable alternatives. Typical applications include industrial control systems, medical equipment, communications and networking line cards, and military/aerospace embedded control where high gate density, instant-on operation, and design security matter. Supply-chain listings also associate the A54SX32 family with industrial and medical equipment designs. Design consideration: as an OTP antifuse device, prototype iterations require new devices for each design change; plan logic verification thoroughly in simulation before programming. The commercial temperature grade (no I suffix) is specified for 0C to +70C operation.

A54SX32-2BG329 - 32K-Gate SX FPGA, 320MHz, BGA-329 | Microchip
The Microchip Technology (Microsemi/Actel) A54SX32-2BG329 is a high-performance antifase-free CMOS FPGA from the SX family, delivering 32,000 equivalent gates, 2880 configurable logic blocks (CLBs), and a maximum toggle rate of 320 MHz in a 329-ball BGA package with 249 user I/Os. It operates from a nominal 3.3V supply (3.0V to 3.6V range) with 5V-tolerant input capability, fabricated on a 0.35 um CMOS process. 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, sitting within the broader hierarchy of programmable logic devices: SPLDs, CPLDs, and FPGAs, all under the umbrella of programmable system-on-chip and digital logic ICs. The SX family uses a sea-of-modules architecture, which simplifies design timing closure, reduces design cost and power consumption, and shortens time to market for performance-intensive applications. Key features of the A54SX32-2BG329 include the speed-grade -2 rating (the fastest commercial grade of the SX32 family), the high-density 329-ball BGA package suited to fine-pitch surface-mount assembly, and 249 I/Os for wide data-path designs. The CMOS process yields low static power, and the sea-of-modules routing architecture provides predictable, register-to-register delays that support synchronous designs above 100 MHz in practical use. Technically, the SX family achieves its performance through a module-based fabric rather than lookup-table (LUT) based architectures, with each module implementing combinational and sequential functions directly. This delivers higher gates-per-micron efficiency and faster inter-module routing than contemporaneous SRAM FPGAs, while the antifuse-style programming keeps configuration nonvolatile. Typical applications include telecommunications line cards, industrial control and data-acquisition systems, test and measurement instrumentation glue logic, and military/aerospace subsystem logic replacement, where high gate utilization and deterministic timing matter. Designers should verify the supply sequencing and 5V-tolerant I/O interfacing requirements early, and confirm the -2 speed grade is required; slower -1 grade parts in the same BG329 footprint can reduce cost.

A54SX32-2BG329I - 48K-Gate FPGA, 249 I/O | Microchip Technology
The Microchip Technology A54SX32-2BG329I (originally Actel) is an SX-family antifuse FPGA with 48,000 system gates, 249 user I/O, and speed grade -2, housed in a 329-ball BGA (329-BBGA) package and rated for the industrial temperature range. An FPGA (Field-Programmable Gate Array) is a programmable integrated circuit that lets designers implement custom digital hardware logic after manufacturing. The Actel SX family is an antifuse-based FPGA: unlike SRAM FPGAs, its programming connections are permanent one-time fuses, which makes the configuration non-volatile, instant-on at power-up, and inherently resistant to configuration corruption - a hierarchy that places this device within programmable logic > FPGA > one-time-programmable antifuse FPGA. Key features of the SX family include a sea-of-modules architecture that delivers high-performance, high-integration levels, simplifying design time and reducing cost and power consumption for performance-intensive applications. The -2 speed grade denotes a faster timing grade within the family, and the 329-ball BGA provides 249 user I/O for large, pin-intensive designs. Architecturally, the sea-of-modules fabric routes through antifuse interconnect, giving the device low on-chip signal loads and deterministic timing suited to high-speed glue logic, bus bridging, and state-machine integration. Because configuration is stored in silicon, no external boot PROM or configuration controller is required. Typical applications include aerospace and defense systems, industrial automation controllers, communications and networking interface bridging, and test-and-measurement instrumentation where instant-on, secure, single-chip logic integration is required. A key design consideration: antifuse FPGAs are one-time programmable - design changes require a new device, so verify timing closure and pin assignment thoroughly before programming. Note also that per distributor data (digchip), this specific MPN is marked Contains Lead / RoHS Non-Compliant; for lead-free assemblies consider the BGG329 lead-free variants.

A Field Programmable Gate Array (FPGA) is a semiconductor device containing a fabric of configurable logic blocks and interconnects that the designer programs after manufacturing. The SX family belongs to the anti-fuse FPGA branch of the programmable logic hierarchy: unlike SRAM FPGAs (Xilinx, Altera), anti-fuse devices are one-time programmable, so their configuration is non-volatile, resistant to radiation-induced configuration upsets, and available immediately at power-up without an external boot device. Key features of the A54SX32-BG313M include the SX sea-of-modules architecture, which delivers gate-array-like routing efficiency and timing predictability; 249 user-input/output pins brought out on the 313-ball footprint; dual-rail operation supporting both 3.3V-class logic and 5.0V-tolerant legacy systems; and the M-grade temperature offering for extended-temperature and defense-oriented programs. Technically, the sea-of-modules fabric combines combinational and sequential modules with segmented routing, giving deterministic interconnect delays that simplify high-performance synchronous design closure compared with SRAM FPGA architectures. Because configuration is stored in anti-fuse elements, there is no configuration bitstream to load, no configuration controller to design, and a dramatically reduced single-event-upset exposure - the reason SX parts persist in avionics, space, and industrial systems designed around them. Typical applications include glueless bus bridging in 5V industrial systems, military and avionics control logic, high-speed state machines and address decoders, and telecom line-card control where non-volatile, instant-on programmable logic is required.
