A54SX72A-FPQG208 - 108K Gate Antifuse FPGA 208-QFP | Microchip
MPN: A54SX72A-FPQG208 ✓ نشطA54SX72A-FPQG208 نظرة عامة
An antifuse FPGA is a field-programmable gate array whose interconnect is permanently programmed at power-up programming time via an antifuse element. Unlike SRAM FPGAs, antifuse devices are non-volatile, require no external configuration ROM, are immune to configuration readback, and draw very low static power - placing them in the hierarchy of programmable logic alongside CPLDs and one-time-programmable ASIC alternatives.
Key features include the 108K system gate density (72,000 typical usable gates), 171 user I/O, and quadrant clock inputs (CLKA-CLKD) for flexible global clock distribution. The antifuse fabric provides low on-resistance interconnect and inherent design security because the programmed configuration cannot be read out. Support for TTL, LVTTL, LVCMOS2, 3.3V PCI, and 5V PCI I/O standards gives broad system-level interface compatibility.
The SX-A architecture uses sea-of-modules logic with combinational and sequential modules, enabling high internal toggle rates for state machines, glue logic consolidation, bus interfaces, and address decoding. The 350 MHz internal capability supports counters and pipeline stages far beyond typical CPLD speeds.
Typical applications include industrial control, aerospace and defense systems (where configuration volatility matters), telecommunications line cards, and legacy system re-designs that consolidate multiple discrete devices into a single-chip solution for board-space and BOM savings.
Design consideration: antifuse devices are one-time programmable - verify your design thoroughly in simulation (Libero IDE/Designer flow) before programming, since a design change requires a new physical device.
This page adds value beyond the manufacturer datasheet by synthesizing distributor pricing, pin-compatible PQ208 alternatives within the SX-A family, and practical design notes for one-time-programmable design flows.

التطبيقات النموذجية
A54SX72A-FPQG208 مناسب لـ 6 التطبيقs: Aerospace and Defense Systems, Industrial Control and Automation, Telecommunications Line Cards, Legacy System Redesign and BOM Consolidation, Test and Measurement Equipment, Secure and Tamper-Resistant Logic.
Aerospace and Defense Systems
The A54SX72A-FPQG208 fits aerospace and defense payloads because its antifuse configuration is one-time-programmable and non-volatile: there is no configuration bitstream to read back, corrupt, or upset, which addresses the single-event configuration-upset weakness of SRAM FPGAs. With 108,000 system gates, 6,036 CLBs, and 171 user I/O in a 2.5V-core process, it integrates telemetry formatting, bus interfaces, and sequencing logic in one PQFP-208 device with low static power. Designers typically implement interface and glue logic at internal rates up to 350 MHz, then verify timing statically before irreversible antifuse programming. Screening variants and documentation support are available through Microchip for flight programs.

Industrial Control and Automation
In industrial controllers, the A54SX72A-FPQG208 consolidates address decoding, state machines, interrupt handling, and bus bridging that would otherwise occupy multiple CPLDs and discrete logic. The instant-on, non-volatile antifuse fabric means the board is functional the moment power is applied - no configuration controller or boot flash is required, improving system availability in factory equipment. The 171 user I/O with TTL, LVTTL, LVCMOS2, and 5V PCI compatibility lets it interface directly to legacy 5V backplanes and modern 3.3V logic alike. Its 250 MHz system capability easily covers PLC scan logic and encoder interfaces, while the PQFP-208 package suits standard surface-mount assembly.

Telecommunications Line Cards
Telecom line cards benefit from the A54SX72A-FPQG208's combination of high internal performance (350 MHz) and 3.3V PCI / 5V PCI I/O compliance, making it a natural PCI bus interface and backplane-logic device. The 108K-gate fabric implements framing, counting, and multiplexing functions at line rates within the 250 MHz system envelope, while quadrant clock inputs (CLKA-CLKD) distribute low-skew clocks to per-quadrant logic. Because the antifuse configuration cannot be read out, design IP on carrier equipment is protected, and the non-volatile startup eliminates configuration latency during hot-swap sequences. The 208-pin QFP footprint also simplifies rework on legacy card designs.

Legacy System Redesign and BOM Consolidation
Many aging platforms used multiple Actel SX devices or dozens of 5V TTL parts; the A54SX72A-FPQG208 lets engineers consolidate that logic into a single 108K-gate, single-chip solution, cutting board area, BOM count, and power. Its 5V PCI and TTL-tolerant I/O directly replaces LS-TTL glue on legacy buses without level shifting, and the antifuse non-volatility preserves the fielded system's instant-on behavior. Microchip explicitly positions SX-A for generating system-wide savings by integrating multiple functions at low cost. Because the package is a standard 208-pin QFP, drop-in migration from other SX-A PQ208 variants requires only speed-grade confirmation, not a PCB respin.

Test and Measurement Equipment
Bench instruments and automated test fixtures use the A54SX72A-FPQG208 for trigger logic, counter/timer channels, and interface bridging. The 6,036 CLBs sustain deep counter chains and pipelined comparators at internal rates up to 350 MHz, enabling nanosecond-class event timing, while 171 user I/O provides dense channel counts for fixture adapters. Deterministic, non-volatile configuration means the instrument is ready at power-up without boot delay - important for production-floor uptime. The 2.5V core keeps dynamic power reasonable in always-on rack equipment, and the one-time-programmable fabric guarantees the shipped instrument's logic cannot be inadvertently altered in the field.

Secure and Tamper-Resistant Logic
Where logic IP or key-handling glue must resist extraction, the A54SX72A-FPQG208's antifuse technology provides inherent design security: after programming, the configuration exists as physical antifuse connections that cannot be read back electrically, unlike SRAM FPGA bitstreams stored in external flash. Within the 108K-gate fabric, designers implement authentication state machines, key XOR masking, and access-control logic with 171 I/O across mixed TTL/LVTTL/LVCMOS2 domains. Non-volatile startup also avoids the configuration-glitch window SRAM systems exhibit at power-on, hardening the system against boot-time attack. Verify all timing before programming, since the secure configuration is permanent.

ملاحظات التصميم
The A54SX72A-FPQG208 is antifuse (one-time programmable). Complete behavioral simulation, place-and-route timing signoff in Microchip Designer, and static timing analysis BEFORE burning the device - an engineering change after programming requires a new physical part. Order prototype quantity accordingly and reserve engineering silicon for iterations. Do not treat it like an SRAM FPGA where you can re-flash after bring-up issues.
The SX-A core runs at 2.5 V while I/O banks support TTL, LVTTL, LVCMOS2, 3.3V PCI, and 5V PCI. Confirm board rail availability for the 2.5 V core supply and provide adequate decoupling (bulk plus 0.1 uF ceramic per supply pin group). Antifuse devices have very low static power, so thermal design is usually straightforward, but dynamic power scales with toggle rate - high-speed counters at 350 MHz-class internal rates dominate consumption.
Use the four dedicated quadrant clock inputs (CLKA-CLKD, mapped to bottom-left, bottom-right, top-left, and top-right quadrants) for global clocking rather than routing clocks through general fabric - Microchip's application note on A54SX72A quadrant clocks details supported macros. Keep clock edges away from other QFP pins in layout, and follow 5V PCI / 3.3V PCI loading rules when interfacing PCI buses to guarantee VOL/VOH and setup margins.
