Typical Applications

A54SX72A-2FGG256 is suitable for 6 applications: Industrial Control and Automation, Telecommunications and Networking Line Cards, Aerospace and Defense Logic Consolidation, Medical Equipment Interface Bridging, Legacy System Life-Cycle Extension, Test and Measurement Instrumentation.

🏭

Industrial Control and Automation

The A54SX72A-2FGG256 fits industrial control boards because its antifuse configuration is present at power-up with no boot device, eliminating configuration-failure failure modes in PLC I/O cards and motor-drive sequencers. The 108K-gate fabric with 6036 logic cells consolidates glue logic, encoders, bus interfaces, and state machines into one 2.5 V CMOS device, while 203 user I/Os bridge parallel field buses and sensor arrays. The 313 MHz speed-grade -2 timing comfortably exceeds industrial clock needs, so designs close timing with margin on routing-dominated paths.

Recommended

🌐

Telecommunications and Networking Line Cards

In telecom line cards, the A54SX72A-2FGG256 provides deterministic, instantly available control logic for framer interfacing, backplane handshaking, and maintenance-channel processing. Its 2.5 V 0.25 um CMOS process yields moderate dynamic power at line-card clock rates, and the antifuse fabric avoids the configuration load transient SRAM FPGAs impose on card power sequencing. With 203 user I/O and up to 313 MHz toggle capability, the device maps typical SONET/Ethernet framing glue and register banks, and quadrant clock networks (CLKA/CLKB/QCLK) distribute low-skew clocks across the 256-ball FGG256 footprint.

✈️

Aerospace and Defense Logic Consolidation

The antifuse architecture of the A54SX72A-2FGG256 suits defense electronics where configuration immutability and read-back protection matter: the programmed netlist cannot be dumped, providing inherent IP protection, and no external configuration flash exists to corrupt. The M-screened family variants (e.g., A54SX72A-FGG256M) support military screening flows. The 108K-gate capacity replaces multiple MSI/PLD devices in avionics interface adapters, reducing board area and part count, while 2.5 V core operation limits static draw in power-constrained platforms.

💊

Medical Equipment Interface Bridging

Medical diagnostic equipment benefits from the A54SX72A-2FGG256 as a glueless bridge between sensor front ends, DSPs, and system backplanes. Instant-on antifuse configuration means the instrument is functional the moment power is applied - valuable for patient-safety interlock logic that must never wait on configuration loading. The 6036-cell fabric implements interrupt controllers, FIFO glue, and parallel interfaces; 203 user I/O covers multi-channel connectivity, and the deterministic, read-back-protected fabric supports design-security requirements of proprietary medical algorithms.

Legacy System Life-Cycle Extension

For obsolete ASIC, PLD, or discrete-logic replacement, the A54SX72A-2FGG256 provides a low-cost single-chip integration path: its 108K gates absorb multiple legacy PAL/GAL/22V10 and SSI/MSI devices, and the stable Microchip/Microsemi supply line supports long-term programs. Because the antifuse device requires no configuration PROM, the retrofit drop onto an existing 5 V-to-2.5 V level-shifted board is simplified, and the FGG256 1.0 mm-pitch footprint exists in multiple speed grades so future board builds can pivot between grades without PCB change.

Recommended Products Summary

What is the A54SX72A-2FGG256?

The A54SX72A-2FGG256 is a Microchip Technology (Actel/Microsemi heritage) SX-A family antifuse FPGA with 108,000 system gates, 6036 logic cells, and 203 user I/Os in a 256-ball FBGA package. It is one-time programmable on a 0.25 um CMOS process at a 2.5 V core supply, with speed grade -2 supporting toggle rates up to 313 MHz. According to Microchip's SX-A family datasheet, it is the largest member of the SX-A antifuse FPGA family.

What are the key specifications of A54SX72A-2FGG256 that engineers should know?

Engineers should know these five facts about the A54SX72A-2FGG256: 108,000 system gates (72,000 typical gates) with 6036 logic modules; 203 user I/O; 2.5 V supply on a 0.25 um CMOS antifuse process; speed grade -2 with up to 313 MHz performance; and a 256-ball fine-pitch BGA (FGG256) at 1.0 mm pitch. It is one-time programmable, so configuration is retained at power-up with no external boot flash and cannot be read back, giving strong design security.

Where to buy A54SX72A-2FGG256 online?

The A54SX72A-2FGG256 can be purchased from authorized distributors including DigiKey Electronics, Mouser Electronics, and LCSC Electronics, where it is listed as in stock at DigiKey and LCSC. LCSC lists pricing starting at $272.15 as of 2026-09-03. XAIPART also offers this part with quantity-break pricing from 1 to 1000 units; request a quote on this page for volume orders or hard-to-schedule requirements.

What is the price of A54SX72A-2FGG256?

The A54SX72A-2FGG256 costs approximately $272.15 per unit at quantity 1 according to LCSC pricing as of 2026-09-03. Pricing typically steps down at volume: expect roughly 5-20% reductions at 10, 100, and 1000+ unit quantities depending on distributor and stock position. Because this is a mature antifuse FPGA, check multiple distributors and broker stock with traceability, as pricing varies significantly with lot date code and remaining inventory.

What is the best drop-in replacement for A54SX72A-2FGG256?

The best same-package drop-in alternatives are other A54SX72A family members in the FGG256 package: A54SX72A-FGG256M, A54SX72A-1FGG256M, and A54SX72A-FG256. These share the identical 256-ball FBGA footprint and pinout, differing mainly in speed grade (-1 vs -2) and temperature/grade suffix (M = military-grade screening). Per FindIC cross-reference data, the terminals and packages are consistent across these variants, so replacement does not require modification of the existing circuit, though the design must be recompiled and reprogrammed for the new speed grade.

What is the difference between A54SX72A-2FGG256 and A54SX72A-1FGG256?

The only functional difference is the speed grade: the -2 suffix denotes the fastest commercial grade (up to 313 MHz toggle rate), while the -1 grade is one step slower, typically roughly 15-20% lower performance on routing-dominated paths. Both share the same 108K gate fabric, 203 user I/O, 2.5 V supply, and identical FGG256 256-ball package and pinout. A design meeting timing at -1 can run on -2 with margin, but a design compiled for -2 may fail timing on -1 without recompilation and verification.

A54SX72A-2FGG256 vs A54SX32A-2FGG256I - which should I choose?

Choose the A54SX72A-2FGG256 when your design needs the larger fabric: 108K gates and 6036 logic cells versus the SX32A's 36K gates and 2016 modules. The SX72A also offers more user I/O (203 vs 172 in the same FGG256-style package class). Choose the A54SX32A-2FGG256I when cost, power, or a smaller gate count is the priority and your netlist fits its fabric - the -I industrial temperature suffix also suits harsher environments. Both use 2.5 V antifuse architecture and the same design flow (Libero/M Designer toolchain).

Is A54SX72A-2FGG256 suitable for industrial control applications?

Yes, the A54SX72A-2FGG256 is well suited to industrial control. Its antifuse OTP fabric powers up instantly with its configuration already fixed - no configuration flash or boot sequence - which improves reliability in industrial panels and motor-control line cards. The 108K gate capacity consolidates glue logic, bus interfaces, and sequencers into one 2.5 V CMOS device, and the 313 MHz capability comfortably covers industrial timing requirements. For extended-temperature installations, verify the temperature suffix of the specific orderable variant before committing the design.

When should I choose an antifuse FPGA like A54SX72A over an SRAM FPGA?

Choose the A54SX72A antifuse FPGA when instant-on configuration, design security, or single-chip integration matters more than reprogrammability. Because the antifuse netlist cannot be read back and needs no external boot device, it resists bit-stream cloning and reduces BOM count versus SRAM FPGAs. Choose an SRAM FPGA instead when you need in-system reconfiguration, frequent design updates, or very large modern fabric. For legacy cost-sensitive, security-sensitive, or aerospace-leaning designs, the SX-A remains a rational choice despite its one-time-programmable constraint.

Can a cross-brand FPGA replace the A54SX72A-2FGG256 pin-for-pin?

No practical cross-brand pin-to-pin replacement exists for the A54SX72A-2FGG256. Its antifuse 256-ball FGG256 footprint and pinout are specific to the Actel/Microchip SX-A family, and Xilinx, Intel (Altera), Lattice, and Gowin devices do not offer pin-compatible 256-ball equivalents with matching 2.5 V core architecture. Any cross-brand migration is a functional redesign requiring PCB rework, pin reassignment, and design re-entry. For footprint-preserving replacement, stay within the SX-A family speed-grade and temperature-suffix variants.

Where to download the A54SX72A-2FGG256 datasheet PDF?

The A54SX72A-2FGG256 datasheet is available as the Microchip 'SX-A Family FPGAs' datasheet PDF at ww1.microchip.com (document sxa_ds.pdf), covering the full family including the A54SX72A device architecture, DC and AC parameters, package mechanicals, and programming information. Distributor sites such as DigiKey, LCSC, and EEWORLD also mirror the PDF. Because the datasheet is family-level, always confirm the FGG256 package mechanical drawing and speed-grade -2 AC tables for your specific ordering code.

Where can I find the A54SX72A-2FGG256 pinout?

The A54SX72A-2FGG256 pinout is documented in the package pinout tables of the Microchip SX-A family datasheet, listing all 256 balls with their I/O, VCC, VCCA, GND, VPP, and dedicated clock assignments. Because a 256-ball BGA pin table is large and board-specific, designers typically import the vendor-provided symbol from the Libero/Designer toolchain libraries rather than transcribing it manually. The ball assignment is identical across the A54SX72A FGG256 speed-grade variants, so the same PCB footprint serves -1 and -2 parts.

Hey Google, what can replace the A54SX72A-2FGG256?

The closest drop-in replacements for the A54SX72A-2FGG256 are same-family parts in the identical 256-ball FGG256 package: A54SX72A-FGG256M, A54SX72A-1FGG256M, and A54SX72A-FG256. These keep the same footprint and pinout with different speed grade or screening level. No cross-brand FPGA is pin-compatible. If footprint change is acceptable, functional replacements require redesign of the PCB, power (2.5 V core), and HDL re-entry into a modern FPGA family - plan for weeks of re-verification, not a simple part swap.

Is the A54SX72A-2FGG256 the same as the A54SX72A-2FGG256M?

Not exactly. The A54SX72A-2FGG256M is the military-screened (M suffix) version of the same die, package, and speed grade -2, sharing the identical FGG256 footprint and pinout with 108K gates, 6036 cells, and 313 MHz performance. The base -2FGG256 targets commercial/industrial temperature and screening levels, while the M variant carries military-grade processing and typically commands a substantial price premium and longer lead time. Electrically the fabric is the same; choose based on program-level screening requirements.

Is A54SX72A-2FGG256 still in production and in stock?

Yes, the A54SX72A-2FGG256 remains an active Microchip product, and DigiKey lists it as in stock with same-day shipping as of 2026-09-03; LCSC also shows stock. As a mature antifuse FPGA from the Actel lineage, it is subject to allocation cycles, so for production programs it is prudent to secure buffer stock or a last-time-buy position. Alternative speed grades in the same FGG256 package are often available when the exact -2 grade is constrained.

What power supply design considerations apply to the A54SX72A-2FGG256?

The A54SX72A-2FGG256 operates from a 2.5 V core supply with additional programming-voltage and analog supply pins (VPP/VCCA) per the SX-A datasheet power scheme. Because it is an OTP antifuse device, there is no configuration power surge at power-up; static and dynamic current depend on clock frequency and toggle activity. Decouple each supply ball group with local 0.1 uF ceramics plus bulk capacitance, follow the datasheet's recommended power-up sequencing, and tie unused programming pins per the datasheet application guidance during normal operation.

Selection Guide

Choose the A54SX72A-2FGG256 when you need the maximum SX-A capacity (108K gates, 6036 cells, 203 user I/O) in the 256-ball FGG256 footprint at speed grade -2 (up to 313 MHz), with instant-on antifuse configuration and read-back-protected design security. Choose A54SX72A-1FGG256M if your program requires military screening and timing closes at -1 speed grade. Choose A54SX72A-FGG256M or A54SX72A-FG256 for screened or base-grade builds where cost dominates and routing slack is ample. Choose A54SX32A-2FGG256I when the netlist fits 36K gates and price or industrial temperature grade matters more than capacity. Never migrate to A54SX72A-2FGG484 without accepting a PCB redesign - its 484-ball package shares the die but not the footprint. All FGG256 parts share one PCB footprint, enabling speed-grade and screening swaps without board change.

Design Notes

The A54SX72A-2FGG256 operates from a 2.5 V core supply with separate VCCA (analog/plant) and programming-voltage (VPP) pins per the SX-A family datasheet power scheme. Provide local 0.1 uF ceramic decoupling at each supply ball group plus bulk capacitance near the device. Because antifuse fabric draws no configuration surge, inrush is governed only by clock activity; still, follow the datasheet's power-up ramp-rate and sequencing guidance to avoid latch-up on mixed-rail boards that also carry 3.3 V or 5 V logic.

This is a one-time-programmable antifuse device: a design or pinout error discovered after programming consumes the part. Always close timing in the Libero/Designer toolchain at speed grade -2, run full post-layout simulation, and lock the pin assignment report before sending the design to the antifuse programmer. Keep the netlist, pin report, and programming file under revision control - the programmed device cannot be read back, so the source database is the only recovery path.

The FGG256 package uses a 1.0 mm ball pitch, allowing 4-mil (0.1 mm) via-in-pad or dog-bone fanout on standard 6-8 layer PCBs. Plan a fanout region of at least two escape rows around the 16x16 ball field, and reserve inner layers for the 2.5 V core plane to minimize IR drop. Dedicated clock balls (CLKA/CLKB/QCLK quadrants) should route to low-skew, length-matched traces; consult the SX-A datasheet package pinout tables before finalizing the footprint, since ball assignments differ from SRAM-FPGA BGA conventions.
