A54SX72A-PQ208M - 108K-Gate SX-A Antifuse FPGA | Microchip
MPN: A54SX72A-PQ208M ✓ פעילA54SX72A-PQ208M סקירה
An antifuse FPGA is a type of field-programmable gate array whose interconnect is permanently configured at power-up programming time via antifuse links. Unlike SRAM-based FPGAs from Xilinx or Intel (Altera), antifuse devices are non-volatile and one-time programmable: the configuration is stored physically in the silicon, requires no external configuration ROM, boots instantly, and is inherently resistant to configuration readback, making the SX-A family a historical choice for secure, high-reliability industrial and aerospace logic designs.
Key features of the A54SX72A include 108,000 available system gates, a 0.25 um CMOS process technology, system-level toggle rates up to 217 MHz on the core, and up to 360 user-programmable I/O across the full family. The device provides multiple global and quadrant clock networks (CLKA, CLKB and QCLK resources) for low-skew clock distribution, and single-chip integration replaces multiple ASSPs or glue-logic devices for system-wide cost savings.
Architecturally, the SX-A fabric consists of combinatorial modules and sequential modules arranged in clusters, with a fine-grained routing architecture. The 0.25 um process delivers low static power compared to SRAM FPGAs of the same era, and the antifuse interconnect adds near-zero routing capacitance, supporting performance with low power consumption.
Typical applications include industrial control and automation, secure communications and encryption interfaces, military and avionics subsystems, test equipment, and bus-interface or bridge logic where instant-on, tamper-resistant, single-chip integration is valued.
Designers should note that antifuse FPGAs are one-time programmable: a design change requires a new physical device, so thorough simulation before programming is essential. Also, being a legacy product line, new designs should verify lifecycle availability.

יישומים טיפוסיים
A54SX72A-PQ208M מתאים עבור 6 יישוםs: Industrial Control and Automation, Secure Communications and Encryption, Military and Avionics Subsystems, Test and Measurement Equipment, Legacy Board Repair and Obsolescence Management, Single-Chip System Integration / Glue Logic.
Industrial Control and Automation
The A54SX72A-PQ208M integrates PLC glue logic, bus bridges and sequencing functions into a single 108K-gate antifuse chip, replacing multiple ASSP and discrete devices for system-wide cost savings. Its instant-on, non-volatile antifuse configuration means the controller is functional within nanoseconds of power application - no configuration loader, no boot delay and no external flash to corrupt in electrically noisy factory environments. The 171 user I/O in the 208-pin PQFP provides ample parallel interface capacity for backplane and sensor-bank connectivity, and the 2.5V core on a 0.25 um process keeps static power low in always-on control cabinets.
מומלץ
Secure Communications and Encryption
Antifuse configuration data cannot be read back from a programmed A54SX72A, giving designers inherent protection against bitstream extraction and IP cloning that SRAM FPGAs cannot match without battery-backed security. This makes the 108K-gate device well suited to encryption engines, authentication blocks and proprietary protocol converters in defense and commercial secure-comms equipment. The device's 217 MHz-class internal toggle capability supports DES/AES-era datapath widths, and quadrant clock networks (CLKA, CLKB, QCLK) allow clean low-skick clocking of multiple independent cipher domains within one chip.
מומלץ
Military and Avionics Subsystems
The A54SX72A-PQ208M's non-volatile antifuse fabric is immune to configuration upsets that affect SRAM cells, eliminating the need for configuration scrubbing in flight-critical logic. The device has a documented history in military programs - it carries an NSN (National Stock Number 5962-01-565-2592) and was originally produced by Actel, the supplier of choice for rad-tolerant antifuse FPGAs. Its 208-pin PQFP package supports conventional through-inspection surface-mount assembly used in defense depots, and its 171 user I/O accommodates MIL-STD bus interfaces and parallel data converters common in avionics line-replaceable units.
מומלץ
Test and Measurement Equipment
Bench instruments and ATE fixtures frequently need flexible sequencing, trigger logic and bus translation that the A54SX72A-PQ208M handles with its 108K gates and 2,012 flip-flops. Instant-on operation means the instrument is ready as soon as power stabilizes - important for equipment that must capture events at power-up. The PQFP package's gull-wing leads simplify rework in low-volume instrument production, and the low static power of the 0.25 um antifuse process keeps self-heating inside a closed instrument enclosure minimal, reducing calibration drift of adjacent analog circuitry.
מומלץ
Legacy Board Repair and Obsolescence Management
Thousands of deployed industrial, medical and defense boards use the A54SX72A in the 208-pin PQFP, and repairs demand a pin-compatible, re-programmable-with-original-design substitute. Same-family variants such as A54SX72A-PQG208M and A54SX72A-PQG208I drop directly onto the existing 208-BFQFP footprint with zero PCB changes. Because antifuse devices ship blank, maintenance depots must keep the original design files and a Silicon Sculptor programmer in the repair loop - a logistics consideration that should be planned before the last-time-buy window closes on this legacy product line.
מומלץ
Single-Chip System Integration / Glue Logic
Microchip positions the SX-A family explicitly as a way to 'generate system-wide savings by integrating multiple functions into a low cost, single-chip solution.' The A54SX72A-PQ208M consolidates address decoders, bus arbiters, state machines and interface translators that previously occupied a rack of 74xx logic into one 108K-gate device. This reduces board area, BOM line items and assembly cost, while the non-volatile antifuse fabric removes the external configuration flash that SRAM FPGA glue logic would require. The 2.5V core also simplifies power-tree design relative to mixed-supply modern FPGAs.

הערות תכנון
Antifuse devices are one-time programmable: a design error after programming renders the physical device unusable. Complete full functional simulation and post-place-and-route static timing analysis in Libero/Designer before releasing the design to the Silicon Sculptor programmer. Budget for a programming yield margin (typically one spare device per 5-10 programmed units) in production planning.
The A54SX72A runs from a 2.5V core supply on a 0.25 um CMOS process with low static current. Provide solid 2.5V decoupling (0.1 uF ceramic per power pin group plus bulk capacitance) and verify inrush during antifuse programming, which differs from normal operating current. When interfacing to 3.3V logic, check I/O tolerance limits in the SX-A datasheet electrical characteristics before direct connection.
Use the dedicated global clock resources (CLKA, CLKB) and quadrant clocks (QCLK) rather than general-purpose routing for clock distribution; Microchip application notes on A54SX72A quadrant clocks describe the supported macros and skew characteristics. Keep clock trace lengths matched on the PCB and avoid routing clocks adjacent to wide switching buses to preserve timing margin at design frequencies approaching the family limits.
The 208-pin PQFP has 0.5 mm pitch gull-wing leads. Follow IPC-recommended land patterns, and allow keep-out areas around the package for inspection and rework access. Because PQFP leads are mechanically compliant, avoid board flex during assembly; a damaged lead on an OTP device can force scrapping the entire programmed part.
