A54SX72A-2FG484 Übersicht
An antifuse FPGA is a one-time-programmable (OTP) programmable logic device whose interconnect switches are permanently formed at programming time. Within the programmable logic hierarchy (FPGA -> field programmable gate array -> programmable logic device -> semiconductor), antifuse FPGAs occupy the non-volatile, high-security niche: unlike SRAM FPGAs they need no configuration ROM, power up instantly with no configuration time, and their bitstream cannot be read back, making them a staple in military, aerospace, and industrial designs where IP protection matters.
Key features include 0.25 um/0.22 um CMOS antifuse technology, 2.25V to 2.75V core supply with mixed 3.3V/2.5V/1.5V-capable I/O banks, 360 available I/Os in the FBGA-484 package, and registered per-module performance up to 294 MHz. The SX-A architecture uses a sea-of-modules fabric with C-cells (combinational) and R-cells (sequential), each driving local and long-line routing for predictable, ASIC-like timing.
The SX-A family provides a low-cost single-chip integration path that replaces multi-chip glue-logic with one time-safe, secure, low-power device. Design entry uses Libero SoC / Designer software with VHDL or Verilog, and timing is verified post-layout, not estimated.
Typical applications include bridge logic and bus interface integration in industrial equipment, secure control planes in defense and avionics systems, and glueless processor/peripheral interfacing where instant-on and configuration-readback protection are required.
Design consideration: the device is one-time programmable and RoHS non-compliant in this commercial speed grade; verify temperature range (0C to +70C) and soldering process compatibility before commit. For lead-free assembly choose the -2FGG484 green variant with identical footprint.

Typische Anwendungen
A54SX72A-2FG484 ist geeignet für 6 Anwendungs: Industrial Bridge and Glue Logic Integration, Secure Defense and Avionics Control Logic, Processor Peripheral and Bus Interface Bridging, Test and Measurement Instrument Logic, Communications and Networking Line-Card Logic, Legacy System Life-Extension and Obsolescence Redesign.
Industrial Bridge and Glue Logic Integration
The A54SX72A-2FG484 consolidates discrete PLDs, PALs, and bus-transceiver glue logic into a single 108K-gate antifuse device, cutting BOM count and board area. Its 360 user I/Os in the 27x27 mm FBGA-484 handle wide parallel buses between microprocessors, FPGAs, memories, and backplanes, while 2.5V core operation keeps static power low for always-on industrial controllers. Because the antifuse fabric is non-volatile, the board is functional at the instant power is applied - no configuration controller or serial flash is needed, improving system uptime and simplifying safety certification. Timing is deterministic post-layout because the actel antifuse routing is fixed once programmed, an advantage over SRAM FPGA re-timing across power cycles. Design the 2.5V core rail with bulk plus 0.1 uF decoupling per supply pin group and verify the 0C to +70C range covers the enclosure environment, or select the -I industrial grade variant.

Secure Defense and Avionics Control Logic
Antifuse interconnect makes the A54SX72A attractive for defense and avionics subsystems where the programmed netlist must not be extractable: there is no configuration bitstream in external memory to intercept, and the device powers up functional with zero configuration latency - critical for systems with strict boot-time requirements. The 108K-gate capacity implements interfaces such as MIL-STD-1553-style protocol glue, sensor aggregation, and redundant-path voting logic across 360 I/Os. The one-time-programmed fabric also resists single-event configuration upsets that affect SRAM FPGAs, complementing system-level SEU hardening strategies. For airborne platforms specify the -I or higher-grade orderable part numbers covering -40C to +100C, and verify package qualification level against program requirements. This commercial -2FG484 unit suits ground-based and benign-temperature defense electronics; recompile the same Libero design for the industrial or military orderable codes without PCB changes.
Empfohlen
Processor Peripheral and Bus Interface Bridging
The SX-A architecture's R-cell (sequential) rich fabric and 294 MHz-class registered performance suit bus bridges, DMA controllers, memory controllers, and legacy interface translation (PCI-style glue, local bus expansion, proprietary parallel links). The A54SX72A-2FG484 provides enough capacity for a full bridge function plus FIFOs and status registers, with I/O banks supporting 3.3V and 2.5V signaling to interface directly with both legacy 5V-tolerant-adjacent and modern 2.5V logic domains. Because routing is antifuse-fixed, register-to-register delays are stable across temperature and lifetime, simplifying setup/hold closure on wide buses. Designers should budget one module per flip-flop and use Libero timing reports post-place-and-route rather than pre-layout estimates. With a 10-week factory lead time, secure prototype quantities early; the same footprint accepts speed-grade and temperature-grade variants for design reuse across product tiers.
Empfohlen
Test and Measurement Instrument Logic
Instrument makers use the A54SX72A-2FG484 for trigger engines, timing generators, and acquisition-path interface logic where deterministic, fixed routing matters for repeatable measurements. The antifuse fabric delivers cycle-accurate timing that does not drift between power cycles, supporting calibration-stable instruments, while 360 I/Os connect front-end ADCs, comparators, and rear-panel digital buses. The 294 MHz-class module performance supports fast trigger decision pipelines, and the 2.5V core limits power inside thermally constrained chassis. Because the device is one-time programmable, firmware features must be frozen before programming; keep field upgradability in an accompanying microcontroller or reserve a socketed device strategy. For benchtop instruments with controlled environments the 0C to +70C commercial range is adequate; portable or outdoor equipment should use the A54SX72A-2FG484I variant with the identical footprint and pinout.
Empfohlen
Communications and Networking Line-Card Logic
Networking line cards and backplane adapters benefit from the SX-A's balance of gate density and I/O count: the A54SX72A-2FG484 implements framing, deskew, error-checking, and backplane interface logic across 360 I/Os while fitting a compact 27x27 mm footprint. Fixed antifuse routing yields consistent latency between identical channels - important for deskew and channel-matching functions - and non-volatile configuration eliminates the boot delay that SRAM FPGAs add before links can train. The 2.5V core supply integrates with standard telecom 2.5V/3.3V rail architectures. Note that this commercial temperature grade and non-green package may not suit telecom-temperature or RoHS-restricted products; the A54SX72A-2FGG484 green variant and -I industrial units share the same footprint, letting one PCB layout serve multiple compliance and temperature markets with only ordering-PN and recompile changes.
Empfohlen
Legacy System Life-Extension and Obsolescence Redesign
When legacy ASICs, ECL glue, or discontinued PLDs reach end-of-life, the A54SX72A-2FG484 is a practical consolidation target: 108K gates absorb multiple obsolete devices, and the SX-A family's long-lived, mature 0.25 um process keeps the replacement available for years - itself an obsolescence-mitigation feature. Migrating requires translating original netlists or RTL into VHDL/Verilog, recompiling in Libero, and validating I/O levels against the original 3.3V/2.5V domains. The antifuse one-time-programming model mirrors masked-ASIC behavior, easing qualification for systems where firmware upgradeability is not required. Budget the 10-week factory lead time into redesign schedules and consider dual-sourcing speed/temp grades (for example A54SX72A-FFG484 alongside the -2 grade) to hedge allocation. Pin-compatible family variants allow one board design to be populated according to availability.

- Faster speed grade for timing-critical paths (vs. A54SX72A-FFG484)
Designhinweise
Provide separate 2.5V (VCCA, core/analog) and I/O-bank (VCCI) rails with independent local decoupling: at least 0.1 uF ceramic at every supply pin group plus 10 uF bulk per rail. Never share the core rail with noisy I/O switching loads; SX-A antifuse devices draw negligible static core current once programmed, so the core regulator can be sized mainly for transient and I/O currents. Observe the 2.25V to 2.75V core tolerance and follow the SX-A datasheet power-up guidance, since core-before-I/O or simultaneous rails are acceptable but brown-out during programming/verification is not recoverable on a one-time-programmable device.
The FBGA-484 uses a 1 mm ball pitch on a 27x27 mm body; specify a standard NSMD pad (approximately 0.4 mm pad on 0.5 mm mask opening) and use via-in-pad with filled vias or dogbone fanout on 1.0-1.2 mm channel pitch. Route power and ground through dedicated ball arrays and flood at least two internal planes to keep I/O return paths short. For assembly, note that this standard -2FG484 package is RoHS non-compliant: lead-free reflow profiles may not be qualified for it, so either specify the green A54SX72A-2FGG484 for lead-free lines or confirm the solder process with your contract manufacturer before production.
Antifuse devices are one-time programmable - a design error after programming cannot be patched, so always run full post-layout timing simulation and functional verification in Libero/Designer before committing silicon. Account for the roughly 10-week factory lead time when scheduling prototypes, and reserve identical-footprint alternates (A54SX72A-2FGG484 for RoHS, -2FG484I for temperature) in the same design database so a compliance or temperature change requires only a recompile. Do not extrapolate timing from the -2 grade to the -F grade; each speed grade has its own timing model that must be selected in the software.
Compliance-Informationen
RoHS non-compliant per Microchip USA listing (standard package finish); the A54SX72A-2FGG484 green variant is the compliant option. Commercial temperature grade (0C to +70C), not automotive qualified.
