A54SX72A-PQG208 概要
An antifuse FPGA is a one-time-programmable (OTP) field-programmable gate array in which programmable interconnect points are formed by antifuse links that permanently connect or isolate routing resources. Within the programmable logic hierarchy, it sits as a device-level component under the FPGA category, itself a branch of programmable logic devices (PLDs) within semiconductors. Because the configuration is hard-wired rather than stored in SRAM, antifuse FPGAs power up instantly with no external configuration ROM, exhibit very low static power, and resist design extraction, making them structurally more secure than SRAM-based alternatives.
Key features include a 217 MHz internal toggle-rate class performance, TTL, LVTTL, LVCMOS2, 3.3V PCI, and 5V PCI compatible input levels, dedicated quadrant clock inputs (CLKA through CLKD) for the A54SX72A die, and single-chip integration that replaces multiple glue-logic devices. The SX-A architecture combines a sea-of-modules logic fabric with a segmented routing structure, delivering deterministic, low-jitter timing compared with larger SRAM FPGAs.
Technical depth: the 0.25 um CMOS process and antifuse interconnect give the device low net capacitance and low static current, while the flip-flop-rich cluster modules support pipelined datapaths at clock rates approaching 217 MHz. Speed grades and temperature variants (standard, I for industrial, M for military, A for automotive) share the same die and footprint.
Typical applications include industrial control and glueless bus bridging, aerospace and defense secure logic, and telecom line-card control, where instant-on operation, low power, and configuration tamper resistance matter.
Design consideration: because the device is one-time programmable, verify the design thoroughly in simulation and use the Libero design flow before programming; plan I/O assignments against the 171 available pins early, since antifuse routing is not re-targetable after programming.

主な用途
A54SX72A-PQG208 の用途: 6 件s: Industrial Control and Glue Logic Integration, Aerospace and Defense Secure Logic, Telecom Line Card Control, Automotive Electronic Control Units, Test and Measurement Instrument Logic, Legacy 5V PCI Bus Bridging.
Industrial Control and Glue Logic Integration
The A54SX72A-PQG208 fits industrial control backplanes and PLC I/O modules where multiple PLD, PAL, and glue-logic devices are consolidated into one chip. Microchip positions SX-A devices as generating system-wide savings by integrating multiple functions into a low-cost single-chip solution. With 108,000 system gates and 171 available I/O, the device absorbs address decoders, bus bridges, interrupt controllers, and state machines in one footprint, and its TTL, LVTTL, LVCMOS2, and 5V PCI compatible inputs interface directly with legacy industrial bus logic. Because the antifuse configuration is non-volatile, the board boots instantly after power-on with no configuration ROM, improving uptime in factory automation equipment where every reset cycle costs production time.
おすすめ
Aerospace and Defense Secure Logic
Antifuse FPGAs like the A54SX72A-PQG208 are structurally resistant to bitstream extraction because the design is physically burned into the interconnect rather than stored in an external configuration flash, which is why the military-grade A54SX72A-PQG208M variant exists. Defense avionics and secure communications modules exploit the 108K-gate fabric for protocol shaping, encryption wrappers, and deterministic control logic with timing that closely matches static timing analysis due to low-capacitance antifuse routing. Instant-on behavior after power application suits safety-critical subsystems that cannot tolerate configuration latency, and the low static power of the 0.25 um process benefits conduction-cooled or battery-backed platforms with limited thermal budgets.
おすすめ
Telecom Line Card Control
Telecom line cards and network interface boards use the A54SX72A-PQG208 for framing control, backplane bus interfacing, and board-level housekeeping logic. The four dedicated quadrant clock inputs (CLKA through CLKD) on the A54SX72A die feed clock distribution networks so timing domains can be allocated per board region, and the 217 MHz class internal performance covers T1/E1 and SONET-adjacent overhead processing. Input compatibility with 3.3V PCI and 5V PCI specifications allows direct attachment to legacy CompactPCI backplanes common in carrier equipment. Since antifuse configuration is immune to configuration upsets that occasionally affect SRAM FPGAs from noisy telecom power environments, the device reduces field-failure mechanisms in always-on infrastructure hardware.
おすすめ
Automotive Electronic Control Units
The automotive variant A54SX72A-PQG208A, documented in the Actel SX-A Automotive Family datasheet, extends this device into ECU body control, gateway, and instrumentation logic where 12V-mains transients and wide temperature ranges are routine. The 72K-gate listing with 4024 cells at 217 MHz provides enough capacity to integrate dash cluster sequencing, sensor polling, and CAN-adjacent control glue in a single 208-pin PQFP. Antifuse one-time programming prevents field tampering of the logic image, a compliance advantage for immobilizer-adjacent functions, and the non-volatile configuration removes the boot-time configuration read that SRAM FPGAs require, letting automotive modules meet strict crank-start timing windows. Standard and A-grade parts share the same footprint, easing qualification reuse.
おすすめ
Test and Measurement Instrument Logic
Bench instruments, data-acquisition systems, and automated test equipment use the A54SX72A-PQG208 as the deterministic control fabric between converters, counters, and host interfaces. Deterministic antifuse routing produces repeatable propagation delays between builds, which matters when firmware revisions must not perturb calibrated timing measurements, and the 2,012 dedicated flip-flops support parallel capture pipelines at rates approaching the 217 MHz family limit. The 171 user I/O pins drive front-panel indicators, relay controls, and multiple sensor buses simultaneously without external decode logic. Because the design is burned in once, EMI and power characteristics are stable across the production run, simplifying EMC pre-compliance for instrument manufacturers.
おすすめ
Legacy 5V PCI Bus Bridging
The A54SX72A-PQG208 supports 5V PCI input levels directly per the Microchip SX-A datasheet, making it one of the few still-stocked fabrics able to bridge legacy 5V signaling, such as industrial PCI/CompactPCI backplanes, to modern 3.3V or LVCMOS2 subsystems without level shifters. Designers map the PCI state machine plus target bridging logic into the 108K-gate array, using quadrant clock inputs to phase-align the bus clock domain. Single-chip integration removes the discrete PAL chains typical of 1990s-era PCI boards, reducing board area and failure points in systems that must stay in service for decades. Availability is constrained by the December 2025 EOL, so last-time-buy planning is essential for this use case.

設計ノート
This is a one-time-programmable antifuse device: once programmed there is no rework path. Complete gate-level simulation, static timing analysis, and I/O assignment review in the Microchip Libero (formerly Actel Designer) flow before generating the fuse file. Reserve spare I/O on the 171 available pins for future ECOs, and lock the quadrant clock assignment (CLKA-CLKD on the A54SX72A) early, because clock network allocation is fixed at programming time.
The 208-pin BFQFP requires attention to fine-pitch soldering: 0.5 mm pitch leads demand a well-controlled reflow profile and inspection of lead coplanarity, since QFP leads are prone to bending during handling. Provide a solid ground plane under the package and decouple each supply pair with 100 nF ceramics placed within a few millimeters of the corner power pins. Follow the SX-A datasheet power-up sequence to avoid latch-up during hot insertion into PCI-style backplanes.
Estimated: with the low static current typical of 0.25 um antifuse fabric, quiescent power is small compared with SRAM FPGAs, but dynamic power scales with clock frequency and toggle rate - at 217 MHz with a heavily toggled fabric, budget core current conservatively and verify against the datasheet power calculator. Since exact per-pin current values are not reproduced here, consult the SX-A datasheet DC characteristics table before finalizing the supply rail design.
