A54SX32-2TQG176 - SX FPGA 48K Gates 147 I/O TQFP-176 | Microsemi

The Microsemi (now Microchip Technology) A54SX32-2TQG176 is an SX-family FPGA providing 48,000 system gates and 147 user I/O pins in a 176-pin TQFP (24x24 mm, 0.5 mm pitch) surface-mount package. It operates from dual supply rails of 3V to 3.6V (core) and 4.75V to 5.25V (I/O), with a maximum clock frequency of 320 MHz and a worst-case CLB combinatorial delay of 0.7 ns. An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a matrix of configurable logic blocks (CLBs) interconnected by programmable routing, allowing designers to implement custom digital circuits without fabricating an ASIC. FPGAs sit at the top of the programmable logic hierarchy, below full-custom ASICs and above CPLDs in gate density and flexibility. The A54SX32 uses Actel's sea-of-modules architecture based on antifuse programmable elements. Unlike SRAM-based FPGAs, the antifuse technology is non-volatile and one-time programmable: configuration is fixed at power-up with no external boot device, no configuration bitstream can be read back, and interconnect switch resistance and capacitance are low, enabling the 320 MHz system performance and improved radiation and power characteristics. The 0.35 um CMOS process supports 3.3V/5V mixed-voltage I/O. Key features include 2880 logic modules organized for efficient wide-gate functions, 147 programmable I/Os with mixed 3.3V/5V tolerance, a -2 commercial speed grade, and a 176-TQFP footprint that eases assembly on standard PCB processes. Microchip describes the SX family as dramatically reducing design time, cost, power consumption, and time to market for performance-intensive applications. Typical applications include industrial control and automation logic, communications and networking glue logic and bridge functions, avionics and defense systems requiring non-volatile, configuration-security-friendly devices, and high-speed state machines replacing multi-chip TTL/ASIC solutions. Designers should note that antifuse FPGAs are one-time programmable: unlike SRAM FPGAs, design iterations require new physical parts, so verification flow maturity matters. Supply both the 3.3V core and 5V I/O rails with proper decoupling and power sequencing per the Microchip SX family datasheet.

A54SX32-BG313I

A54SX32-BG313I - 32k Gate FPGA, 249 I/O, 313-BGA | Microsemi

The Microsemi (Microchip) A54SX32-BG313I is a 32,000-gate SX-family antifuse FPGA in a 313-ball BGA (BBGA) package, offering 249 user I/O, 2880 configurable logic modules, and clock rates up to 240 MHz at a nominal 3.3V supply (3.0V to 3.6V operating range). An antifuse FPGA is a type of field-programmable gate array whose interconnect switches are permanently programmed at power-up programming time, in contrast to SRAM-based FPGAs that load configuration data from external memory at every boot. Within the programmable logic hierarchy (FPGA -> programmable logic device -> digital IC -> semiconductor), antifuse devices are valued for instant-on behavior, non-volatile configuration, low power, and high resistance to configuration error or radiation-induced upset. Key features include the SX sea-of-modules architecture that shortens design time and reduces power, dual supply ranges (3V~3.6V core and 4.75V~5.25V per listed specification data), and a dense 35x35 mm 313-PBGA footprint delivering 249 I/O for wide-bus designs. The -I suffix denotes industrial temperature operation. Architecturally, the SX family's sea-of-modules fabric provides predictable routing and high effective gate utilization, supporting performance-intensive applications where SRAM FPGA reconfiguration is unnecessary. Typical applications include industrial control, communications and networking line cards, aerospace and defense logic glue, and test equipment, where non-volatile, instant-on logic is required. Design consideration: because antifuse programming is one-time, complete functional simulation and pin-planning verification before programming are essential; there is no field rework path.

A54SX32-BG313M

A54SX32-BG313M - SX FPGA 249 I/O 313-BBGA | Microsemi

The Microsemi (Actel) A54SX32-BG313M is a 36,000-gate-class SX family anti-fuse FPGA with 249 user I/O, housed in a 313-ball BGA (313-BBGA / 313-PBGA, 35x35 mm) package, operating from dual supply rails of 3.0V to 3.6V and 4.75V to 5.25V. 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. When designing with this device, verify that both supply rails meet the 3.0V-3.6V and 4.75V-5.25V windows and confirm the -M grade against your program temperature requirement before layout.

The Microsemi (Microchip) A54SX32-BG329 is a 48,000-system-gate antifuse FPGA from the SX family, offering 2,880 logic cells, 249 user I/O, and system speeds up to 240 MHz, housed in a 329-ball plastic BGA (31x31 mm, 1.27 mm pitch) surface-mount package. It operates from dual 3.3V and 5.0V supply rails (3.0V-3.6V and 4.75V-5.25V). An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a matrix of configurable logic blocks that designers interconnect using a hardware description language such as Verilog or VHDL. FPGAs sit within the broader hierarchy of programmable logic devices, above CPLDs in density and below ASICs in per-unit cost efficiency, and the SX family uses an antifuse programming technology that is one-time programmable but inherently more secure and radiation-tolerant than SRAM-based alternatives. Key features of the A54SX32-BG329 include the sea-of-modules architecture, which delivers ASIC-like routing efficiency and deterministic timing, a 0.35 um CMOS process, dual-voltage operation that lets 5V-tolerant I/O interface with legacy 5V systems while core logic runs at 3.3V, and the high-density 329-BGA package providing up to 249 simultaneous user I/O for wide bus interfaces. Technically, the device organizes its 48,000 system gates into 2,880 configurable logic modules, with Register Transfer Level timing models in Libero IDE supporting synthesis and timing-driven place-and-route. Antifuse interconnects add virtually no parasitic delay compared with pass-transistor SRAM routing, which is why SX devices reach 240 MHz counter frequencies and suit performance-critical glueless logic integration. Typical applications include industrial control and automation, communications and networking equipment, test and measurement instrumentation, and military/aerospace system upgrades where the secure, non-volatile antifuse fabric is valued. The dual 5V/3.3V capability makes it particularly convenient for retrofit designs on older 5V boards. Design consideration: the antifuse fabric is one-time programmable, so verify the design fully in simulation before programming production devices; also budget for the 329-BGA footprint and plan power sequencing for the dual rails.

A54SX32-BG329I

A54SX32-BG329I - 48K Gate SX FPGA 329-BGA | Microchip

The Microchip Technology (Microsemi) A54SX32-BG329I is an Actel SX-family antifuse FPGA with 48K system gates (1800 logic cells), 249 user I/O, and system performance up to approximately 240 MHz, housed in a 329-ball plastic BGA (329-BBGA) package with 1.27 mm ball pitch and industrial temperature rating (I suffix). An antifuse FPGA is a type of field programmable gate array whose interconnect is permanently programmed at power-up programming time: unlike SRAM-based FPGAs from Xilinx or Intel (Altera), the SX family stores its configuration in one-time-programmable antifuse elements, so the device is non-volatile, requires no external configuration ROM, and is inherently resistant to configuration upset - a key reason antifuse FPGAs remain popular in military, aerospace, and industrial systems. Within the power management hierarchy of system logic devices, the SX sits in the one-time-programmable FPGA class alongside Microchip's newer ProASIC and RTAX families. Key features include the sea-of-modules architecture delivering high-speed, low-jitter interconnect; dual voltage support of 3.3V core with 5V-tolerant I/O capability (3.3V/5V per FindIC data); 0.35 um CMOS process technology; and 2880 combinatorial logic blocks (CLBs) equivalent cells. The 249 user I/O in the 329-ball package gives high pin utilization for wide bus interfaces. Technical depth: the SX sea-of-modules architecture shortens routing delays versus channel-based architectures, enabling consistent propagation performance. Because programming is one-time, designers validate the bitstream once and gain the supply-chain and security benefits of a fixed-function device without configuration-boot time. Typical applications include aerospace and defense control logic, industrial automation controllers, communication bridge logic, and glueless interface integration in legacy systems where SRAM FPGA volatility is undesirable. Design consideration: antifuse devices cannot be reprogrammed - a design change requires a new physical part, so thorough simulation and a proven programming flow (Libero/Designer software) are essential before committing.

A54SX32-BG329M

A54SX32-BG329M - 32K Gate FPGA 240MHz 329-BGA | Microsemi

The Microsemi (Actel, now Microchip Technology) A54SX32-BG329M is an antifuse-based FPGA from the SX family delivering 32,000 system gates (1,800 logic cells) with a maximum toggle frequency of 240 MHz, housed in a 329-ball BGA (329-BBGA) package with 249 user I/O. 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. Within the programmable logic hierarchy, the SX family sits among high-performance, one-time-programmable (OTP) antifuse FPGAs, which contrasts with SRAM-based FPGAs: configuration is permanent, immune to configuration-readback, and requires no external boot configuration device. Key features include a sea-of-modules architecture enabling high logic utilization and predictable timing, dual-rail operation at 3.3V or 5V (3.0V-3.6V and 4.75V-5.25V supply ranges), 2,880 configurable logic modules, and 0.35 um CMOS process technology. The -M speed grade indicates standard performance; -1 and -2 grades offer faster timing. Antifuse programmability delivers very low static power and instant-on operation. Architecturally, each logic module drives fast local and long-line routing, allowing critical paths to run at frequencies up to 240 MHz, and typical combinational delays in the sub-nanosecond range (datasheet cites a 900 ps representative delay for the SX family). Security against design theft is inherent because the programmed antifuse pattern cannot be read out. Typical applications include industrial control, aerospace and defense logic replacement, telecommunication line cards, and ASIC prototype or glue-logic consolidation where non-volatile, instant-on programmable logic is required. Design consideration: as a one-time-programmable device, verify the design thoroughly in simulation and, if possible, prototype on a larger SX-A family device before programming production units. Power-up sequencing of the 3.3V and 5V rails should follow the datasheet guidelines.

The Microchip Technology A54SX32-BGG329 is a 32,000-system-gate antifuse FPGA from the Actel SX family, offering 2880 logic cells, 249 user I/O, and up to 240 MHz internal performance, housed in a 329-ball BGA (329-BBGA) package. It operates from 3.3V/5V supplies and is 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. Within the programmable-logic hierarchy, the SX family sits among one-time-programmable (OTP) antifuse FPGAs, which sit above SPLDs/CPLDs in gate density. Unlike SRAM FPGAs, antifuse devices are non-volatile, secure, and require no configuration PROM, making them attractive for high-reliability and space-constrained systems. Key features include a sea-of-modules architecture that yields high routing efficiency and deterministic timing, 3.7 ns pin-to-pin clock-to-output, 0.1 ns input setup, and 0.25 ns clock skew. The device supports 66 MHz PCI integration as a single-chip solution, combining CPLD and FPGA functions without external glue logic. Technically, the SX family uses a fine-grained sea-of-modules fabric built around C-cells (combinational) and R-cells (register), giving near-ASIC logic utilization. The antifuse interconnect provides low parasitic capacitance, supporting the 240 MHz internal clock rate and lower static power than equivalent SRAM FPGAs. Typical applications include industrial control, communications and networking line cards, avionics and military subsystems requiring design security, and PCI-compliant interface bridging where the 66 MHz PCI capability eliminates a separate bridge chip. Designers should note that this is a one-time-programmable device: the design must be finalized before programming, and speed-grade selection (-1, -2, standard) directly affects the achievable internal frequency.

The Microchip Technology (Microsemi/Actel) A54SX32-BGG329I is a 32,000-system-gate antifuse FPGA from the SX family with 2,880 logic cells, 249 user I/O, and up to 240 MHz internal system performance, housed in a 329-ball plastic BGA (329-BBGA) package in an industrial-grade (I-suffix) temperature variant. A Field-Programmable Gate Array (FPGA) is a user-configurable integrated circuit whose internal logic is defined after manufacturing rather than fixed at the fab. Within the semiconductor hierarchy, an FPGA sits above fixed-function logic (CPLD, standard logic) and below ASICs in volume economics: it offers ASIC-like integration without mask costs or NRE. The Actel SX family uses a sea-of-modules architecture built on antifuse programmable interconnect, which is one-time programmable but keeps configuration data non-volatile and resistant to readback. Key differentiating specifications include 320 MHz internal toggle-class performance, 3.7 ns pin-to-pin clock-to-out, 0.1 ns input setup time, and 0.25 ns clock skew - timing figures that allow the SX32 to replace multi-chip CPLD/FPGA combinations and to implement 66 MHz PCI logic in a single-chip solution. The 0.35 um CMOS process supports dual 3.3V core / 5V tolerant I/O operation. Architecturally, the SX family's sea-of-modules structure eliminates the long routing delays typical of channel-based FPGAs, so timing is predictable and largely independent of placement. Because antifuse interconnect adds no configuration cell capacitance in the signal path, the device achieves performance-intensive operation at reduced power versus SRAM FPGAs of comparable capability, and its design is inherently secure since no bitstream is stored on chip. Typical applications include 66 MHz PCI bus interfaces, industrial control and automation, aerospace and defense logic integration (where the I-grade industrial variant is common), communications line cards, and single-chip glueless integration of previously discrete CPLD and FPGA functions. Design consideration: antifuse FPGAs are one-time programmable, so logic must be verified thoroughly in simulation with Actel (Microchip) Libero-style toolchains before programming; there is no in-system reconfiguration as with SRAM FPGAs.

A field-programmable gate array (FPGA) is a semiconductor device containing programmable logic blocks and interconnects that designers configure after manufacturing. The SX family sits in the broader hierarchy of FPGA -> programmable logic device -> digital IC, and specifically uses Actel's antifuse (one-time programmable) technology rather than SRAM configuration, which means the configuration is non-volatile, immediately active at power-up, and inherently resistant to configuration readback. Key features of the A54SX32-CQ208 include its sea-of-modules architecture, which delivers high gate utilization and predictable timing; dual-voltage operation (3.0 V to 3.6 V core/I/O and 4.75 V to 5.25 V for 5 V-tolerant systems); 174 programmable I/O pins supporting legacy 5 V interfaces; and the ceramic CQFP package with a tie bar, which provides excellent thermal and mechanical robustness for military-style and high-reliability sockets. The antifuse fabric also eliminates the need for external configuration storage such as flash or boot PROMs, reducing bill-of-material cost and board area. Technically, the SX architecture uses a sea-of-modules approach with combinable C-cells and R-cells, enabling dense pipelined designs at up to 205 MHz. Routing resources are rich and local, keeping interconnect delays short and predictable, which is why the SX family was widely adopted in performance-intensive data-path, glue-logic consolidation, and embedded control designs. Typical applications include industrial control systems, communications and networking equipment, aerospace test instrumentation, and legacy 5 V system upgrades where a non-volatile, instantly-on FPGA is required. When designing with this device, note that antifuse programming is one-time only: final logic must be verified in simulation before programming, and the dual-supply system requires careful power sequencing to avoid latch-up during mixed-voltage bring-up.

Technically, the SX architecture combines dedicated registers with combinatorial modules, enabling register-heavy pipelines at clock rates up to 238 MHz. Because antifuse interconnect has no SRAM configuration bitstream overhead, the device offers lower static power and inherent resistance to configuration upset compared with SRAM FPGAs, an important attribute in radiation-tolerant and secure system designs. Typical applications include military avionics glue logic and bus interfaces, spacecraft and missile electronics, industrial systems requiring secure one-time-programmable logic, and legacy design sustainer builds where the SX family was originally designed in. A key design consideration: this part is RoHS non-compliant due to lead-containing ceramic package terminations, so it is restricted to military and aerospace exemptions.

The antifuse fabric is inherently non-volatile and immediately active at power-up, requiring no configuration device, which improves security and simplifies the power supply design. Technically, the SX family uses a sea-of-modules architecture in which each module is a compact logic cell implementing both combinational and registered functions. Because routing is performed by sub-micron antifuse elements rather than SRAM pass gates, the device achieves ASIC-like speed and low power with very low switching noise, while remaining reprogrammable at the device level only in the sense of one-time programming at programming time. Typical applications include high-reliability and long-lifecycle systems such as industrial control, avionics and defense platforms, communications infrastructure glue logic, and bus-interface bridging where 66 MHz PCI integration and single-chip logic consolidation are required. A key design consideration is that antifuse FPGAs are one-time programmable: the design must be fully verified before programming, and engineering changes require new devices.

Unlike SRAM-based FPGAs from Xilinx or Altera, antifuse devices are non-volatile, radiation-tolerant by nature of their architecture, and immune to configuration bitstream interception, making them a member of the broader programmable logic family that also includes CPLDs and flash-based FPGAs. Key features of the A54SX32-CQ256M include the sea-of-modules architecture that delivers ASIC-like routing efficiency, 0.35 um process technology supporting up to 205 MHz system performance, dual-rail power operation (3.3V core/I-O and 5.0V tolerant supply range) for mixed-voltage systems, and a ceramic package suited to high-reliability and extended-temperature environments. Technically, the SX family uses a patented sea-of-modules fabric built from combinational and sequential logic modules, giving deterministic, short interconnect delays that distinguish it from SRAM FPGA architectures. Design entry and implementation are performed with Actel/Microsemi Libero SoC (Designer) tooling, and the design is one-time-programmable, which removes the need for an external configuration PROM and reduces board-level BOM cost. Typical applications include aerospace and defense signal processing, industrial control, communications infrastructure glue logic, and bridge/interface functions where 5V compatibility and non-volatile one-time programming are required. The 203 user I/O capacity supports wide parallel bus interfacing in legacy backplane systems. A key design consideration is that antifuse devices cannot be reprogrammed: verify the design fully in simulation before programming production units, and note that the CQFP package requires careful socket or solder handling due to its lead-frame construction.

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. Unlike SRAM FPGAs, the SX family uses antifuse programming technology, which is one-time programmable: the configuration becomes a permanent, non-volatile connection at power-up with no external configuration device, no configuration time, and inherently high resistance to design theft and SEU-induced reconfiguration issues. Key features of the A54SX32-PQ208 include a sea-of-modules architecture for high logic utilization with 100% pin locking, 3.0V to 3.6V core operation (nominal 3.3V) with 5.0V-tolerant capability via dual-rail support of 4.75V to 5.25V, and timing performance of 320 MHz internal toggle with 3.7 ns pin-to-pin clock-to-out, 0.1 ns input set-up, and 0.25 ns clock skew. These characteristics support 66 MHz PCI single-chip integration. The sea-of-modules floorplan covers the entire die with a grid of logic modules built around C-cells and S-cells, enabling predictable routing and full-resource utilization. The antifuse fabric yields low static power consumption compared to SRAM FPGAs of similar capacity. Typical applications include glueless 66 MHz PCI designs, industrial control, communications line cards, military/aerospace subsystems requiring non-volatile, instant-on programmable logic, and as a drop-in capacity upgrade path within the SX family. Design consideration: because the device is one-time programmable, verify the full design via simulation before programming the antifuses; there is no in-system reconfiguration.

The device supports 66 MHz PCI designs as a single-chip CPLD/FPGA integration solution, and its 3.3 V operation with 5.0 V tolerant inputs simplifies interfacing to legacy 5 V TTL buses. Technically, the A54SX32 is fabricated in a 0.35 um CMOS process and contains 2,880 LABs/CLBs organized as a sea of C-cells and R-cells. This fine-grained architecture yields deterministic timing: clock skew is held to 0.25 ns and clock-to-out to 3.7 ns across the full 174 I/O, allowing high-frequency state machines and PCI interfaces to close timing without iterative floorplanning. Typical applications include PCI bus interface logic, glueless system integration replacing multiple CPLDs and ASSPs, industrial automation controllers, and defense/industrial systems requiring non-volatile, single-chip programmable logic with long-term availability. Design consideration: the device is one-time programmable, so prototype thoroughly in simulation and verify I/O assignments before programming; there is no in-system reprogramming fallback.

A54SX32-TQ176

A54SX32-TQ176 - 32K-Gate SX FPGA, TQFP-176 | Microchip

The Microchip (Actel/Microsemi) A54SX32-TQ176 is a 32,000-system-gate antifuse FPGA from the SX family, built on a 0.35 um process with up to 240 MHz performance, 147 user I/Os, and a 176-pin TQFP (24x24 mm) surface-mount package operating from a 3.3 V (3.0 V to 3.6 V) core supply with 5.0 V (4.75 V to 5.25 V) I/O capability. An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a fabric of programmable logic blocks and interconnects that engineers configure after manufacturing, sitting in the hierarchy of programmable logic below full-custom ASICs and above fixed-function logic ICs. The SX family differs from SRAM-based FPGAs because it uses antifuse programming elements: the configuration is one-time programmable (OTP), non-volatile, and inherently immune to configuration-readout attacks and radiation-induced configuration upsets. Key features of the A54SX32 include a sea-of-modules architecture with 2880 logic modules, dual-voltage operation (3.3 V core, 5 V-tolerant I/O), and deterministic interconnect that delivers ASIC-like timing predictability. According to the Microchip SX family datasheet, the family was designed for performance-intensive applications requiring dramatic reductions in power consumption compared with SRAM FPGAs. Technically, the 0.35 um antifuse process provides low routing capacitance, which is the root cause of the SX family's speed advantage: signals travel through fewer buffered segments, so critical paths see lower delay and jitter. The OTP nature also removes the configuration PROM and power-up configuration time required by SRAM FPGAs, improving system boot behavior andglitch resistance. Typical applications include telecommunications and networking line cards, industrial control, aerospace and defense payloads, and test equipment glue-logic consolidation, where the combination of 32K gates, 147 I/Os, and 5 V-tolerant I/O matches legacy board designs. A critical design consideration is that this commercial-temperature (0 to 70 C) leaded part is obsolete and RoHS non-compliant; new designs should use the green A54SX32-TQG176 variants or plan a lifecycle strategy.
