A54SX72A-2PQ208 概要
An antifuse FPGA is a type of field-programmable gate array whose interconnects are permanently programmed at power-up by blowing microscopic antifuse elements. Unlike SRAM-based FPGAs, antifuse devices are non-volatile, require no configuration ROM, boot instantly, and are inherently resistant to bit-stream readback, which makes them a class of programmable logic within the broader power/logic semiconductor hierarchy favored for high-reliability and secure designs.
Key features include 108,000 available system gates, 171 user-programmable I/O pins in this package (up to 360 across the family), a proprietary 0.25 micron CMOS process, and instant-on non-volatile configuration. The '-2' speed grade offers the standard commercial performance point of the SX-A family, balancing logic density, I/O count, and cost for single-chip integration of glue logic, bus interfaces, and control functions.
The SX-A architecture uses a sea-of-modules fabric with C-cell (combinational) and R-cell (sequential) logic modules, plus dedicated decoders and quadrant/global clock networks (CLKA, CLKB, QCLK) that support multiple clock domains with low skew. Actel (now Microchip) designed the family for low power and high security, with no configuration memory contents exposed externally.
Typical applications include industrial control systems, military and aerospace logic integration, telecommunications line-card control, bus bridging, and secure single-chip consolidation of multiple discrete logic devices.
When designing with this device, verify I/O banking voltage compatibility with adjacent logic families and allocate proper power/ground pin pairs; antifuse programming is one-time, so design margins and timing closure in Libero SoC should be confirmed before release.

主な用途
A54SX72A-2PQ208 の用途: 6 件s: Industrial Control and Automation, Military and Aerospace Logic Integration, Telecommunications Line Cards, Secure Single-Chip System Consolidation, Bus Bridging and Legacy Interface Translation, Test and Measurement Equipment.
Industrial Control and Automation
The A54SX72A-2PQ208 fits industrial control systems that need 108K gates of deterministic, instant-on logic without boot delays. Its 171 user I/O pins in one 208-pin PQFP consolidate PLC I/O decoding, motor-control sequencing, and backplane interface logic that would otherwise occupy dozens of discrete devices. The antifuse fabric is non-volatile, so the controller is functional within microseconds of power application - a meaningful advantage over SRAM FPGAs that need external configuration memory in electrically noisy factory environments. Deterministic 2.5V core logic with 294 MHz toggle capability comfortably handles counter/timer arrays and state machines at industrial clock rates.
おすすめ
Military and Aerospace Logic Integration
Antifuse FPGAs are a long-standing choice in military and aerospace payloads because configuration cannot be read back and there is no configuration memory to corrupt under radiation or power interruption. The A54SX72A-2PQ208 provides 108,000 system gates and 2012 flip-flops for telemetry formatting, bus protocol bridging, and redundancy-management logic, while its instant-on behavior suits power-cycled flight hardware. For these programs, the same-die A54SX72A-PQ208M military-grade variant in the identical 208-pin package supplies the required temperature screening as a drop-in upgrade. Design flows center on Microchip Libero SoC with static timing closure before one-time programming.
おすすめ
Telecommunications Line Cards
Telecom line cards and backplane adapters use the A54SX72A-2PQ208 to glue together T1/E1 framers, microprocessors, and management buses within a single low-power 2.5V device. The SX-A quadrant and global clock networks (CLKA, CLKB, QCLK) support multiple synchronized clock domains with low skew, which matters for framing counters and SONET/SDH-adjacent timing logic. With 171 user I/O, one PQFP-208 device replaces the multi-chip glue arrays common on legacy line-card layouts, cutting BOM count and board rework. Non-volatile configuration removes the boot ROM, increasing uptime in carrier equipment where every reset must be fast and deterministic.
おすすめ
Secure Single-Chip System Consolidation
The SX-A antifuse architecture offers inherent design security: unlike SRAM FPGAs, there is no bitstream in external memory and no configuration readback path, so proprietary logic cannot be cloned by probing the board. The A54SX72A-2PQ208's 108K gates are sufficient to absorb legacy ASIC glue, address decoders, encryption key handling logic, and bus interfaces into one package. Instant-on non-volatility also prevents configuration-period vulnerabilities. This combination makes it attractive for licensing-control hardware, secure communications adapters, and anti-tamper-conscious industrial equipment where the PCB must reveal nothing about the implemented function.
おすすめ
Bus Bridging and Legacy Interface Translation
Many systems must bridge legacy buses (VME, PCI-era backplanes, parallel peripherals) to modern controllers. The A54SX72A-2PQ208 offers 171 user-programmable I/O pins - enough for a full 32-bit address/data bus plus control strobes - with 5V-tolerant family I/O options and the -2 speed grade supporting interface timing at up to 294 MHz internal toggle rates. Its 2012 flip-flops implement FIFOs, handshake state machines, and bus arbiters. Because the device is one-time programmable, protocol logic is frozen and testable, which simplifies certification of bridge hardware in long-lifecycle industrial and defense platforms that cannot tolerate firmware drift.
おすすめ
Test and Measurement Equipment
Bench instruments and automated test fixtures benefit from the A54SX72A-2PQ208's deterministic timing: antifuse routing gives stable, repeatable propagation delays that do not vary with configuration reload, improving measurement reproducibility. The 108K-gate fabric implements trigger state machines, counters, and pattern generators, while 171 I/O lines interface directly with DUT fixtures. Instant-on configuration matters in rack systems that power-cycle channels frequently. Designers should close timing in Libero SoC with margin before programming, since one-time programmability leaves no field-update path - a trade-off accepted for timing determinism and configuration integrity in metrology environments.

設計ノート
The A54SX72A-2PQ208 operates from a 2.5V core supply. Distribute decoupling - typically 0.1 uF ceramics at each VDD/VSS pin pair around the 208-pin BFQFP perimeter plus bulk capacitance at board entry. Because antifuse devices have no configuration current surge at power-up, inrush is driven mainly by I/O loading; still, sequence I/O bank voltages before or with the core to avoid latch-up paths through input protection structures. Estimated: a fully utilized fabric at moderate toggle rates stays within SX-A family typical ICC ranges published in the manufacturer datasheet.
Use the dedicated CLKA, CLKB, and QCLK (quadrant clock) resources for clock distribution rather than routing clocks through general routing. Per Microchip's application notes on A54SX72A quadrant clocks, quadrant clocking reduces skew and preserves timing margins across the 171 available I/O. Keep high-fanout enables on low-skew routes, assign I/O by bank to avoid voltage-domain conflicts, and terminate bus lines according to the SX-A I/O AC characteristics for the -2 speed grade.
The SX-A family is one-time programmable: there is no field reconfiguration path once the antifuse array is programmed. Complete static timing analysis in Microchip Libero SoC at worst-case conditions for the -2 speed grade, and validate the full netlist on a development device before production programming. Do not substitute a slower speed grade (e.g., A54SX72A-PQ208I for the -2PQ208) without re-running timing closure - propagation delays increase at the -1 grade.
