A54SX08A-PQG208I 概要
An FPGA (Field Programmable Gate Array) is a class of programmable logic device that implements digital logic through configurable logic blocks and programmable interconnect. Unlike SRAM FPGAs, the Actel SX-A family uses antifuse programming, which is one-time programmable, non-volatile at power-up, and inherently more resistant to configuration readback attacks. In the device hierarchy, the SX-A sits within programmable logic: FPGA -> antifuse FPGA -> programmable logic device -> digital IC.
Key features include the sea-of-modules architecture built from R-cells (register cells) and C-cells (combinatorial cells) with virtually no routing overhead, fast pin-to-pin timing for predictable interfacing, and 512 logic cells in this density grade. The 238 MHz toggle frequency supports performance-intensive glue logic, bus interfacing, and state machines. The industrial temperature rating and wide supply tolerance suit harsh-environment embedded systems.
Architecturally, the SX-A sea-of-modules floorplan covers the die with a dense grid of logic modules, minimizing chip area lost to interconnect. This yields short, deterministic routing delays compared with LUT-based SRAM architectures, enabling timing that approaches ASIC predictability without NRE cost.
Typical applications include industrial control and automation backplanes, communications line-card glue logic, aerospace and defense ASIC prototyping, and legacy-system redesign where one-time-programmable secure configuration is valued.
Design consideration: antifuse devices cannot be reprogrammed - verify the design fully in simulation (Libero/Designer software flow) before programming, and plan supply decoupling for the 2.5V core and 3.3V I/O rails.

主な用途
A54SX08A-PQG208I の用途: 6 件s: Industrial Control and Automation, Communications Line-Card Glue Logic, Aerospace and Defense Prototyping, ASIC Prototyping and Emulation, Legacy System Redesign and Obsolescence Management, Medical Instrumentation Control Logic.
Industrial Control and Automation
The A54SX08A-PQG208I fits industrial control backplanes and automation I/O cards because its -40C to +85C industrial grade and 2.25V to 5.25V supply tolerance absorb factory-floor supply variation and temperature swings. The 12,000-gate / 130-I/O capacity implements bus interfaces, counters, encoders, and sequencing glue logic between PLC processors and field I/O. Its one-time-programmable antifuse configuration is non-volatile at power-up, so no configuration flash is required and a brown-out cannot corrupt the bitstream - a real reliability advantage over SRAM FPGAs in unattended equipment. Place it on the 5V or 3.3V logic domain boundary with 0.1 uF decoupling per pin pair, and reserve headroom for 238 MHz-class state machines when partitioning the logic.
おすすめ
Communications Line-Card Glue Logic
In telecom and datacom line cards, the A54SX08A-PQG208I implements address decoding, bus bridging, flow-control state machines, and framer-to-PHY glue logic. The sea-of-modules architecture provides short, deterministic routing delays - beneficial when interfacing to backplane timing budgets - and the 238 MHz toggle capability covers OC-3-class and T1/E1 support logic. The industrial I-grade handles central-office ambient ranges, while the 208-pin 28x28 mm PQFP suits standard reflow assembly. Because antifuse configuration cannot be read back, the device also aids design protection in competitive equipment. Re-verify pin-to-pin timing in the Libero/Designer static timing report against the backplane spec before release.
おすすめ
Aerospace and Defense Prototyping
Actel antifuse FPGAs have a long history in defense electronics, and the SX-A family extends that to higher performance. The A54SX08A-PQG208I provides 12,000 gates for prototype and low-volume weapon-system support logic, with configuration that is inherently resistant to readback - no bitstream is stored in SRAM, so no configuration device can be dumped. The non-volatile antifuse also eliminates configuration boot time, which matters in power-critical avionics. For program lifetimes, stock management is simpler because the programmed configuration is permanent. Verify full functionality in simulation before programming since the device is one-time programmable, and use military-supplier stock screening where conformance documentation is required.
おすすめ
ASIC Prototyping and Emulation
Designers migrating from ASIC to programmable silicon use the A54SX08A-PQG208I as a low-cost prototyping target: its R-cell/C-cell sea-of-modules fabric maps fine-grained ASIC-style netlists (muxes, registers, random logic) more naturally than LUT architectures, and its deterministic routing makes timing closure of small ASIC blocks straightforward. The 12,000-gate / 512-cell capacity accommodates controller cores and peripheral blocks, while 130 I/Os connect to logic analyzers or test benches. Because antifuse parts are programmed once, treat each device as an expendable prototype: fully simulate, compile with placement constraints mirroring the intended ASIC floorplan, and verify timing in Designer before committing the device.
おすすめ
Legacy System Redesign and Obsolescence Management
For sustaining engineering on aging boards that already use Actel FPGAs, the A54SX08A-PQG208I is a direct-fit continuation device: identical 208-PQFP footprint, industrial temperature grade, and 2.25V to 5.25V supply range mean no PCB change. It can also absorb consolidated TTL/PLD glue logic during a redesign, replacing dozens of 74-series devices with one 12,000-gate device and cutting BOM cost and power. Keep the compiled antifuse programming file under revision control together with the programmer calibration record, since the configuration is permanent. Where future growth is expected, lay out for the pin-compatible A54SX16A-1PQG208I or A54SX72A-1PQG208I and stock the density that fits today.
おすすめ
Medical Instrumentation Control Logic
Benchtop medical instruments - analyzers, patient-interface controllers, and imaging support electronics - benefit from the A54SX08A-PQG208I's non-volatile, one-time-programmable configuration, which eliminates configuration-image corruption as a field-failure mode and shortens power-on time to active logic. The 12,000 gates implement motor-index sequencing, sensor-interrupt handling, and host-interface glue logic, while 130 I/Os cover front-panel and actuator connections. Industrial temperature margins give headroom inside enclosed instruments with limited airflow. Standard PQFP assembly keeps manufacturing simple for contract manufacturers. Validate EMI behavior of the 2.5V core rail with bulk plus 0.1 uF decoupling near the 60 Hz line-powered supply section of the design.

設計ノート
The A54SX08A-PQG208I uses antifuse programming and cannot be erased or reprogrammed. Complete all RTL simulation, place-and-route, and static timing analysis in the Actel/Microsemi Designer (Libero) flow before programming any device. Keep one unprogrammed spare per board in production. Programmed devices cannot be returned to stock, so sample-scale your programming runs and treat each programming session as a committed material decision. Verify the speed grade suffix on incoming parts matches the compiled design's speed grade assumption.
The device operates from a 2.25V to 5.25V supply with a 2.5V nominal core. Although antifuse FPGAs draw less static current than SRAM FPGAs (no configuration memory to hold), simultaneous switching of up to 130 I/Os creates ground bounce. Use one 10 uF to 47 uF bulk capacitor per voltage rail plus 0.1 uF ceramics distributed at alternating VCC/GND pairs around the 208-pin perimeter. Provide solid ground planes and limit outputs switching simultaneously, or stagger edge rates, to keep SSN within I/O timing margin.
The 208-PQFP (28x28 mm, 0.5 mm pitch) requires careful SMT assembly: specify a stencil with 0.15 to 0.18 mm apertures, use no-clean or water-wash flux profiles, and inspect solder joints under the fine-pitch perimeter with AOI. Route the pin-compatible upgrade path (A54SX16A/A54SX72A in the same footprint) into the layout from day one - all family members share the land pattern, so a single PCB can carry the density chosen at build time. Keep high-fanout clock sources on short traces to preserve the fabric's timing predictability.
