A54SX72A-1FGG256M 概要
An FPGA is a semiconductor logic device whose internal gate network can be configured after manufacturing. The SX-A family from Microchip uses antifuse programming elements, so configuration is non-volatile and one-time programmable. In the system hierarchy, this part can be classified as FPGA, programmable logic device, embedded logic chip, and ultimately an integrated circuit. Unlike SRAM FPGAs, antifuse FPGAs require no external boot PROM or SPI flash, eliminating configuration-load failures at startup, improving instant-on response, and reducing BOM area.
Key features include 108,000 system gates, 203 user I/Os, 0.25 µm antifuse CMOS at a 2.5 V core, military case-temperature range of -55°C to +125°C, and ROHS3-compliant FGG package finish. The -1 speed grade is listed at 250 MHz by distributor data, making the device suitable for timing-intensive defense and aerospace logic. The package is a 256-FPBGA, delivered in tray packaging, and Microchip USA reports an active lifecycle status with a 20-week manufacturer lead time.
Technically, SX-A antifuse interconnect is physically programmed during manufacturing, producing predictable low-impedance routing with low power and strong security. The FPGA is live immediately at power-up and has no loadable bitstream to intercept, which reduces the risk of reverse engineering compared with SRAM-based FPGAs that require external configuration memory.
Typical applications include military avionics, secure networking and encryption, industrial control, sensor aggregation, and high-reliability instrumentation. The 108K-system-gate density lets designers consolidate multiple discrete logic and interface functions onto a single-chip solution, lowering board area and total component count.
Because the SX-A device is one-time programmable, complete timing closure and board-level simulation must be finished before programming. Designers should also verify the 256-ball map in the SX-A family datasheet before PCB layout and should confirm the I/O supply strategy because several I/O banks may operate over different voltage ranges.
This page synthesizes distributor pricing, package-specific FPGA alternatives, and practical design guidance that is not always repeated in the manufacturer datasheet, with data verified from Microchip and authorized distributor sources as of 2026-09-03.

主な用途
A54SX72A-1FGG256M の用途: 6 件s: Aerospace and Defense Avionics, Secure Communication Routers and Network Encryption, High-Reliability Industrial Control and Automation, High-Reliability Instrumentation and Data Acquisition, Telemetry and Satellite Ground Station Interface, Legacy FPGA Replacement and Obsolescence Mitigation.
Aerospace and Defense Avionics
The A54SX72A-1FGG256M fits avionics and defense system processing because its military case-temperature rating covers -55°C to +125°C, and antifuse programmability removes external configuration memory that can be corrupted by power interruption or single-event upsets. The 108,000 system gates and 203 user I/Os provide an efficient slice for bus interfaces, discrete I/O consolidation, surface-control logic, and failure-isolation logic. The -1 speed grade supports 250 MHz-class data paths while maintaining deterministic power-up behavior. For harsh environments, package the design with adequate thermal derating and use the JTAG port for board-level test. In larger avionics systems this FPGA can handle sensor preprocessing, actuator command distribution, and power sequencing logic without a soft processor, reducing board complexity and qualification risk.
おすすめ
Secure Communication Routers and Network Encryption
The A54SX72A-1FGG256M is well suited for secure communication systems because its antifuse configuration is permanent and cannot be intercepted as a bitstream. With 108,000 system gates and 203 user I/Os, it can implement packet classification, protocol bridging, CRC engines, or custom encryption state machines. The -1 speed grade provides 250 MHz-class timing for high-throughput datapaths, while the -55°C to +125°C rating supports ruggedized outdoor and airborne networking equipment. Designers can use the device to consolidate FPGA, CPLD, and small serializer functions into one secured component. Since the part is live at power-up, link bring-up time is minimized, which is valuable in redundant network cards that must fail over without long firmware loading delays.
おすすめ
High-Reliability Industrial Control and Automation
In industrial control, the A54SX72A-1FGG256M can replace many discrete logic ICs in PLC I/O modules, motor drives, and robotic controllers. Its 203 user I/Os allow direct connection to optocoupler arrays, encoder interfaces, and digital valve drivers, while the 108,000 system gates absorb glue logic, state machines, and safe-stop functions. The military temperature range gives large margin for sealed enclosures near motors or furnaces, and the instant-on behavior avoids processor boot delays in safety interlocks. Because the device is one-time programmable, firmware cannot be accidentally overwritten in the field, improving reliability. Designers should still verify I/O voltage compatibility with the 24 V industrial buses, as the FPGA core operates at 2.5 V and external level shifting may be required.
おすすめ
High-Reliability Instrumentation and Data Acquisition
The A54SX72A-1FGG256M supports high-reliability instrumentation designs by providing 108,000 system gates, 203 user I/Os, and a 250 MHz -1 speed grade for deterministic control and data formatting. Applications include multichannel data acquisition, waveform capture, sensor linearization, and custom trigger logic. The antifuse architecture adds no startup delay and cannot be altered by unintended writes, which is important for calibration-critical instruments and medical or test equipment used in field environments. The -55°C to +125°C operating range covers thermal chambers and outdoor monitoring stations. With careful I/O bank planning, the FPGA can bridge analog front-end ASICs, ADCs, DACs, and host processors without the need for extra CPLDs, reducing component count and board-level qualification effort.
おすすめ
Telemetry and Satellite Ground Station Interface
The A54SX72A-1FGG256M is useful for telemetry and ground-station equipment because its 203 user I/Os and 108K-system-gate capacity can handle frame synchronization, bit error rate checking, custom UART/SPI bridging, and discrete antenna controls. The military temperature rating of -55°C to +125°C supports unfriendly environmental enclosures and solar-exposed shelters. The non-volatile nature of the SX-A FPGA provides deterministic startup, which is helpful in remote sites where a power cycle must restore operation without an operator loading firmware. With 0.25 µm 2.5 V antifuse technology, the device offers adequate performance for moderate-speed serial streams while keeping power low enough for thermally constrained installations. For evolving telemetry standards, designers can still update surrounding software while the FPGA's hardened functions remain unchanged.
おすすめ
Legacy FPGA Replacement and Obsolescence Mitigation
The A54SX72A-1FGG256M serves legacy FPGA replacement because Microchip continues to list the SX-A family as active, and several same-family 256-ball variants are available as drop-in alternatives. The 108,000 system gates closely match original A54SX72A designs that used smaller CMOS FPGA architectures, while the 203 user I/Os preserve most legacy board-level interfaces. Design teams migrating an older design to this device should verify the original pinout and I/O standard mapping against the SX-A datasheet. The antifuse one-time-programmable profile is also well matched to qualified aerospace/defense programs where design freeze and documentation control are mandatory. For greener manufacturing, the FGG (RoHS3-compliant) package finish is preferred over legacy non-green FG builds.

設計ノート
Because SX-A is an antifuse one-time-programmable family, programming is irreversible. Before programming the A54SX72A-1FGG256M, complete timing closure, simulate board-level I/O, and verify the 256-ball map against the Microchip SX-A Family datasheet. Use the Microchip Libero tool set or a compatible programmer to generate the programming file. There is no configuration bitstream to recover; a wrong fuse pattern can scrap the device and delay the program by weeks. Lock the design revision and record programming log data for military traceability.
Use the actual 256-FPBGA land pattern from the SX-A datasheet instead of a generic BGA-256 pattern. Place decoupling capacitors close to each supply-ball group and provide a solid ground plane for the 203 user I/Os. Because the distributor listing shows a supply range of 2.25 V to 5.25 V while the core is a 2.5 V device, confirm the I/O bank voltages from the datasheet and do not overdrive input pins. For high-speed signals, keep trace lengths matched and avoid routing under the BGA body. Verify fine-pitch fanout vias and assembly clearances with the PCB manufacturer.
The military listing gives an operating case-temperature range of -55°C to +125°C for the A54SX72A-1FGG256M. Estimated power depends on logic utilization and toggle rate; use Microchip's SX-A power-estimation flow early in the design because antifuse routing capacitance is fixed after programming. Provide conduction or forced-air cooling when the FPGA operates near the upper case limit. Remember that the 125°C limit is a case-temperature rating, not an ambient rating; compute junction temperature with the package thermal resistance from the datasheet to ensure derating.
コンプライアンス情報
ROHS3 Compliant according to Microchip USA listing. FGG package denotes green/RoHS-friendly finish; FG variants without the G suffix are legacy non-green and may require RoHS exemption.
