A54SX32A-1TQG100M - 48K Gate FPGA 81 I/O TQFP-100 | Microchip
The Microchip Technology (Microsemi) A54SX32A-1TQG100M is an SX-A family antifuse field programmable gate array (FPGA) with 48,000 system gates, 81 user I/O, and a -1 speed grade, housed in a 100-pin TQFP (TQG100) surface-mount package. It operates from a 2.5V core supply (2.25V to 5.25V per distribution data) and is qualified across the -55C to +125C military temperature range, indicated by the M grade suffix. An FPGA (Field Programmable Gate Array) is a semiconductor device containing a matrix of configurable logic blocks and programmable interconnects that the designer wires together after manufacturing, sitting within the programmable logic hierarchy above CPLDs and below full-custom ASICs. The SX-A family uses Microsemi antifuse technology, in which programmed connections are permanent one-time links. This yields instant-on operation with no configuration PROM or boot time, high resistance to radiation-induced configuration upsets, and low long-term cost for volume production. Key features of the A54SX32A-1TQG100M include its sea-of-modules architecture built on 0.25 um CMOS processing, a maximum toggle rate of approximately 278 MHz, and 1,800 usable logic cells. The -1 speed grade denotes the base speed bin of the SX-A family; -2 and faster grades trade higher power for additional performance. The 100-pin TQFP package provides a 0.5 mm lead pitch in a 14 mm x 14 mm body suitable for cost-sensitive two-layer and four-layer boards. Because antifuse programming is one-time, designs are finalized by simulation and signed off before programming; this makes the family attractive for fixed-function replacements of gate arrays, glue logic consolidation, and defense/aerospace programs where the wide -55C to +125C temperature range and non-volatile, no-boot behavior are decisive. Typical applications include industrial control, avionics interfaces, communications line cards, and military equipment. Design consideration: the part is programmed once, so verify timing with Microchip Libero/Designer software at the -1 speed grade and reserve I/O margin, since no rework is possible after programming.

Key features include a 0.25um CMOS antifuse process, clock speeds up to 278 MHz, low static power consumption typical of the SX-A family, and a low-cost single-chip integration path. The -1 speed grade is the fastest commercial grade in the SX32A lineup, and the 20x20 mm TQFP-144 body with 1.4 mm height suits surface-mount assembly without fine-pitch BGAs. Architecturally, the SX-A family uses a sea-of-modules fabric with combinational and sequential logic modules (C-cells and R-cells) connected by a segmented routing fabric programmed through antifuse links. This structure yields deterministic, low-jitter routing with interconnect delays comparable to gate arrays, making the family a low-risk ASIC or complex-PAL replacement. Typical applications include industrial control glue logic, communication bridging, state-machine integration, bus interfaces, and cost-sensitive system consolidation where a one-time-programmed configuration is a security or reliability benefit. Design consideration: antifuse devices are one-time programmable - prototype on compatible devices or use the Libero/Microsemi design flow with thorough simulation before committing, since design changes require a new device. Verify 2.5V supply rail sequencing and decouple each VCC pin.

A54SX32A-2BGG329 - 48K Gate FPGA, 313MHz | Microchip Technology
The Microchip Technology A54SX32A-2BGG329 (formerly Actel/Microsemi) is a 48,000-system-gate antifuse FPGA from the SX-A family, delivering 2,880 logic cells, up to 249 user I/Os, and a maximum toggle rate of 313 MHz, housed in a 329-ball BGA (BGG329) package. The -2 speed grade device operates from a single 2.5V core supply and is fabricated on a 0.25 um CMOS process. An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a sea of programmable logic blocks and interconnects that designers configure after manufacturing. The SX-A family belongs to the antifuse FPGA category: unlike SRAM-based FPGAs, its interconnect elements are permanently programmed at the factory or in the lab, so the configuration is retained at power-up without any external boot PROM, improving security and reducing BOM count in the power-management hierarchy of a system design. Key features of the A54SX32A-2BGG329 include 48K system gates (32K raw gates, 2,880 logic cells) for integrating glue logic, bus interfaces, and state machines into a single chip; 249 user I/Os in the 329-ball BGA, supporting high-pin-count board layouts; and the -2 speed grade supporting 313 MHz internal performance. The antifuse architecture contributes inherently low power, high immunity to configuration readback, and essentially non-volatile, single-chip integration, which Microchip positions as lowering the performance premium versus competing architectures. Technically, the device uses a sea-of-modules architecture with repeated logic modules (C-cells and R-cells) and a routing fabric programmed by antifuse elements. Because the bitstream is physically burned in, there is no configuration time at power-up and no external configuration device to attack or corrupt, a property valued in defense, avionics, and industrial control where design protection matters. Typical applications include industrial automation and control, communications and networking line cards, test and measurement instrumentation, aerospace and defense subsystems, and bridging/glue logic for processors and ASICs. The large I/O count and deterministic power-up suit designs requiring many interface signals to be live immediately at reset. A key design consideration: antifuse FPGAs are one-time programmable. Unlike SRAM FPGAs, you cannot reconfigure the same device; design iteration requires new parts, so verification in simulation and timing closure with the Libero/Designer flow should be complete before programming production units.

An antifuse FPGA is a type of field-programmable gate array whose interconnects are permanently programmed at power-up of the configuration step rather than stored in SRAM. Unlike SRAM-based FPGAs, antifuse devices are non-volatile, require no external configuration ROM, and are inherently resistant to configuration upset, making them a member of the broader programmable logic and power/cost-sensitive ASIC- replacement hierarchy. The SX-A family targets designers who need one-time-programmable logic integration at ASIC-like unit cost. Key features of the A54SX32A-2FGG256 include 48K system gates (approximately 1,800 logic cells on a 0.25 um antifuse process per FindIC data), 203 available user I/Os in the 256-FBGA package, a -2 speed grade for mid-to-high-speed glueless integration, and RoHS3-compliant surface-mount assembly. Distributed routing and dedicated clock resources support synchronous designs without external glue logic. Technically, the SX-A architecture uses a sea-of-modules fabric with combinational and sequential modules connected by a program-once antifuse interconnect matrix. Because configuration is hard-wired, there is no configuration readback path, which supports designs where bitstream security matters. The 0.25 um process yields predictable timing, and the -2 grade represents the standard commercial speed bin for this family. Typical applications include industrial control and automation glue logic, telecommunications line-card interface bridging, defense and avionics legacy-design sustainment, and ASIC prototype or low-volume production integration where a single-chip solution replaces multiple discrete logic devices. Design consideration: as a one-time-programmable device, functional changes require new silicon, so lock down the design and verify timing with Microchip Libero/Designer software before committing to programming; the commercial 0C to +70C rating also excludes most automotive and extended-temperature industrial deployments.

The antifuse interconnect is non-volatile and inherently single-chip: no external configuration PROM or boot sequence is required, which reduces BOM cost, board area, and configuration-bitstream security exposure compared with SRAM FPGAs. Architecturally, the device combines two logic module types: C-cells (combinatorial logic modules) and R-cells (register cells), embedded in a segmented routing fabric. Because antifuse links are programmed once at the factory-level programming stage, the device exhibits low static power, deterministic interconnect capacitance, and immunity to configuration upsets, making it attractive in harsh environments. Typical applications include industrial control and automation logic, telecommunications line-card glue logic and protocol bridging, aerospace and defense data paths, and medical instrumentation where single-chip integration replaces multi-chip ASSP and discrete logic solutions. Design consideration: because the SX-A is one-time programmable, prototype on the larger A54SX72A same-footprint device first and lock the design before committing programming; also budget I/O bank voltage selection (2.5/3.3/5 V) at layout time.

Key features of the A54SX32A include its antifuse-based, non-volatile programming technology, which removes the need for external configuration memory, offers inherent design security, and provides instant-on operation at power-up. The 249 available I/Os and high routing capacity make it suitable for glue logic integration, bus interfacing, and state-machine implementations that consolidate multiple discrete functions into a single low-cost chip. Technically, the SX-A architecture combines combinational and sequential modules in a sea-of-modules fabric, delivering deterministic, ASIC-like timing. The 0.25um CMOS process keeps static power low while the module structure supports the family's 238 MHz maximum toggle performance. The 329-ball BBGA (ball grid array) package provides a robust surface-mount footprint with a 1.27 mm ball pitch per related sourcing data. Typical applications include industrial automation controllers, military and avionics systems (enabled by the -55C to +125C operating range), communications equipment, and test instrumentation where legacy programmable logic must be maintained without redesign. Designers should note that antifuse FPGAs are one-time programmable: verification of the design before programming is essential, and design iterations require new devices. Power distribution and decoupling across the 329-ball footprint must follow the manufacturer datasheet guidance.

A54SX32A-FBGG329 - 48K Gate FPGA 329-BGA | Microchip
The Microchip Technology (formerly Microsemi/Microsemi Corporation) A54SX32A-FBGG329 is an SX-A family antifuse FPGA with 48,000 equivalent system gates (32,000 typical gates available for user logic), 2,880 logic cells, up to 249 user I/O, and a maximum clock frequency of 172 MHz, housed in a 329-ball FBGA (S-PBGA-B329) package operating at a 2.5 V core supply and fabricated in 0.25 um CMOS technology. An antifuse FPGA is a type of field-programmable gate array in which the programmable interconnect is formed by one-time antifuse elements that are permanently programmed at the factory or in the field. Unlike SRAM-based FPGAs, antifuse devices retain their configuration through power cycles without an external configuration flash, resist configuration readback attacks, and add essentially zero interconnect delay penalty at rest, making them a subclass of programmable logic within the broader power-management and system-logic semiconductor hierarchy. Key features of the A54SX32A-FBGG329 include the sea-of-modules architecture of the SX-A family, which simplifies design migration and enables single-chip integration of multiple functions at low cost. The device combines high performance (system speeds up to 172 MHz), low static power consumption inherent to antifuse technology, and configuration security because there is no bitstream to intercept at power-up. The fine-pitch 329-ball BGA package supports high I/O density for bus-intensive designs. Technically, the A54SX32A uses a 0.25 um CMOS process with a 2.5 V core and supports both combinational and registered logic implemented in C-cells (logic modules) and R-cells (register modules). The SX-A family is supported by Microchip's Libero SoC design suite, and programming is performed once, after which the device behaves as a fixed ASIC-like logic part with immediate power-on operation. Typical applications include industrial control and automation, communications and networking equipment, military and aerospace systems (particularly the M-grade temperature variants), and glue-logic consolidation where an SRAM FPGA's configuration overhead or security exposure is undesirable. Design consideration: because the device is one-time programmable, verify your design thoroughly in simulation and, ideally, on an in-system reprogrammable development path before committing; pin-compatible speed-grade and temperature-grade variants ease late design changes.

It operates from a 2.25V to 5.25V supply over a 0C to +70C commercial temperature range. An antifuse FPGA is a type of field-programmable gate array in which the interconnect configuration is permanently set at programming time by blowing microscopic antifuse links. Unlike SRAM-based FPGAs, antifuse devices are non-volatile with no configuration PROM, offer inherently higher design security because the bitstream cannot be read back, and consume lower static power. Within the programmable logic hierarchy, the A54SX32A belongs to the FPGA -> field-programmable logic -> programmable semiconductor category. Key features include single-chip integration of multiple functions at low cost, support for 2.5V, 3.3V, and 5V I/O standards on the same device, and fabrication on 0.22 um / 0.25 um CMOS antifuse technology. The 203 I/O count enables glue-logic consolidation, bus bridging, and interface conversion in one package. The 256-ball FBGA footprint is shared across the A54SX32A speed and temperature variants, simplifying second-sourcing within the family. Architecturally, the SX-A family uses a sea-of-modules fabric of combinational and sequential modules routed through a metal-metal antifuse interconnect matrix. Because configuration is hard-wired, the device exhibits no configuration-time delay at power-up, making it suitable for applications requiring immediate availability of logic at reset, and it is immune to configuration-upset effects that affect SRAM FPGAs in radiation-prone environments. Typical applications include industrial control and automation glue logic, legacy system refresh where 5V-tolerant I/O is required, telecommunications line-card interface logic, aerospace and defense boards needing secure non-volatile configuration, and bridging between processors and ASICs or memory subsystems. A key design consideration: antifuse devices are one-time programmable. Fix a logic change requires a new device, so complete functional simulation and prototype validation before committing volume production. Also note the commercial 0C to +70C rating; industrial-temperature applications should use the I-suffix variants such as A54SX32A-FGG256I.

An FPGA is a programmable semiconductor device that implements digital logic through configurable function modules and interconnect. The SX-A family sits within the broader hierarchy of programmable logic: FPGA -> programmable logic device -> digital integrated circuit. Unlike SRAM-based FPGAs, the SX-A uses antifuse (Actel-style) technology, meaning its configuration is permanently set at programming time, providing inherent resistance to configuration readback and better security for military and industrial designs. Key features of the A54SX32A include approximately 48,000 equivalent gates (32,000 typical available for user design), 0.25 um CMOS process technology, and a 2.5V core with supply voltage operation spanning 2.25V to 5.25V per distributor data. The fine-pitch BGA footprint (27 x 27 mm) provides high interconnect density for glue logic consolidation, bus bridging, and embedded control. Its non-volatile antifuse architecture requires no boot PROM, eliminating configuration time at power-up. The SX-A architecture combines C-cell (combinational) and R-cell (sequential) logic modules with fast dedicated routing, enabling predictable, ASIC-like timing. System-wide cost savings come from integrating multiple SSI/MSI functions, PALs, and GALs into a single low-cost chip. Typical applications include industrial automation controllers, telecommunications line cards, military/aerospace subsystems (where antifuse radiation tolerance and security are valued), and legacy system sustainment where the design was originally captured in Actel Designer or Libero flow. Design consideration: the FFGG484 speed grade and 0-to-70C commercial temperature range mean industrial designs should consider the -I industrial variant. Because antifuse devices are one-time programmable, reserve spare capacity (roughly 20-30% of cells) and verify the design thoroughly in simulation before programming.

An antifuse FPGA is a type of field-programmable gate array in which programmable connections are formed permanently at programming time using an antifuse element, rather than SRAM configuration cells. In the programmable-logic hierarchy (FPGA -> field-programmable gate array -> programmable logic device -> digital IC), antifuse devices occupy the non-volatile, single-event-immune end of the spectrum: the configuration is stored physically in the silicon, so no external configuration flash is required at power-up. Key features include 0.25 um CMOS antifuse technology, deterministic 1.2 ns-class flip-flop timing cited by distributors, a 238 MHz toggle/system frequency rating, and low static power typical of 2.5 V antifuse architecture. Because the bitstream is physically burned rather than loaded from flash, the device offers inherent design security against readback - a major reason SX-A parts remain popular in defense, avionics, and industrial designs. The SX-A architecture combines fast, dedicated carry chains with the Actel routing fabric, allowing high-speed counters, state machines, and glue-logic integration in a low-cost single-chip solution. According to Microchip, SX-A devices generate system-wide savings by integrating multiple functions into one device while providing a combination of performance, security, and low power. Typical applications include legacy military/aerospace system sustainment, industrial control glue logic, communication bridging, and secure single-chip state machines where SRAM-FPGA configuration vulnerabilities are unacceptable. Design consideration: antifuse devices are one-time programmable - fully verify the design in simulation and, ideally, on a device from the same speed grade before programming production units.

The SX-A family uses Actel's antifuse programming technology, in which one-time programmable interconnect elements are permanently set at programming time, in a so-called sea-of-modules architecture that tiles the die with combinatorial cells (C-cells) and register cells (R-cells) with virtually no chip area lost to routing. Key features of the A54SX32A include a sea-of-modules architecture delivering high gate utilization, antifuse one-time-programmable interconnect that is inherently non-volatile and resistant to configuration readback (a security benefit versus SRAM FPGAs), low static power consumption, and a fine-pitch 256-ball BGA that saves board area. The device integrates multiple glue-logic functions into a single low-cost chip, reducing BOM cost and board space compared with multi-chip TTL/CPLD solutions. Architecturally, the SX-A fabric provides high-speed combinatorial logic through C-cells and dense sequential logic through R-cells, with segment-based routing that supports system clock rates up to several hundred megahertz depending on speed grade. The 'A' speed grade is the standard-timing member of the A54SX32A family; -1 and -2 speed grades offer faster combinatorial delays for higher clock frequencies. Typical applications include industrial control and automation, telecommunications and networking line cards, aerospace and defense systems where one-time programmability and configuration security matter, medical instrumentation, and legacy system sustainment where the A54SX32A replaces multiple ASIC/SSI/MSI devices. Design consideration: because antifuse devices are one-time programmable, verify the design thoroughly in simulation before programming production units, and plan I/O assignments early since the 256-ball BGA footprint is fixed.

Within the semiconductor hierarchy, the FPGA sits under programmable logic, alongside CPLDs and ASICs. Unlike SRAM-based FPGAs from Xilinx or Intel (Altera), the SX-A family uses antifuse programmability: connections are permanently set at programming time, giving the device non-volatile configuration, high security against bitstream extraction, and very low static power. Key features include the sea-of-modules architecture, in which the entire die floor is covered by a grid of logic modules with virtually no area lost to interconnect. The family provides two module types: the combinatorial C-cell and the register R-cell, enabling fast, predictable routing. Antifuse technology also yields radiation-tolerant behavior and instant-on power-up with no external configuration device required. Technical depth comes from the 0.25um/0.22um CMOS process, which supports the 238 MHz system toggle rate - performance levels that made SX-A devices popular where SRAM FPGAs were too costly or power hungry. The 2.5V core supply keeps static current low, while the permanently programmed fabric eliminates configuration-readout attacks common to SRAM FPGAs. Typical applications include aerospace and industrial glue logic integration, bus bridging, state-machine implementations, communications interfacing, and single-chip consolidation of multiple ASSP/PLD functions to reduce board count and system cost. Design consideration: antifuse devices are one-time programmable; final verification must be completed in simulation before programming, and a spare programmed device should be held for production.

The 256-ball FBGA footprint provides high I/O density in a compact surface-mount outline, with 203 pins available as user I/O. Technically, the SX-A architecture uses a sea-of-modules fabric: combinational and sequential C-cells and R-cells are interconnected through a multilayer metal routing mesh whose antifuse links are one-time programmed. Because routing is hard-wired after programming, timing is deterministic and unaffected by configuration reload, a key advantage for aerospace, defense, and industrial designs requiring immediate-on operation and glitch-free boot. The 0.25 um CMOS process delivers low static power and proven reliability data. Typical applications include avionics glue logic and bus interface integration, satellite and space payload control logic, industrial motor and motion control sequencing, medical equipment interface boards, and legacy 5 V system bridges where SRAM FPGAs are unsuitable.
