A54SX08-2PQG208I 概要
An FPGA (Field-Programmable Gate Array) is a semiconductor device that implements custom digital logic through programmable interconnect and logic modules. The SX family uses a sea-of-modules antifuse architecture, which means the programming connections are one-time-programmable rather than SRAM-based. This places the SX family in the broader hierarchy of programmable logic: FPGA -> programmable logic device -> digital IC -> semiconductor. Antifuse FPGAs are non-volatile by nature, requiring no configuration PROM and offering inherent resistance to configuration readback.
Key features of the A54SX08-2PQG208I include a dual supply voltage arrangement of 3.0V to 3.6V (core) and 4.75V to 5.25V (I/O), which supports 5V-tolerant legacy system interfaces. The 0.35um CMOS process delivers deterministic sub-nanosecond-class routing delays, and the '-2' speed grade denotes the faster of the family's standard speed bins. The industrial temperature grade ('I' suffix) supports -40C to +85C operation.
The sea-of-modules architecture eliminates the segmented routing delays of SRAM FPGA architectures, giving designers predictable timing that simplifies high-speed state machine and datapath design. Because programming is antifuse-based, the device is secure against design extraction and draws near-zero static configuration current.
Typical applications include industrial control and automation, bridge and interface logic between 5V legacy buses and 3.3V subsystems, telecommunications line-card glue logic, and military/aerospace systems that require one-time-programmable, configuration-free FPGAs.
When designing with this part, plan the power budget around the dual-rail requirement and verify that your programming programmer supports the SX family antifuse flow.

主な用途
A54SX08-2PQG208I の用途: 6 件s: Industrial Control and Automation, 5V Legacy Bus Bridge Logic, Telecommunications Line-Card Glue Logic, Aerospace and Defense Secure Logic, Medical Instrumentation Control Logic, Test and Measurement Equipment.
Industrial Control and Automation
The A54SX08-2PQG208I fits industrial control and factory automation designs because it combines an industrial -40C to +85C temperature rating with a 5V-tolerant I/O ring supplied from 4.75V to 5.25V, letting it interface directly with legacy PLC backplanes and TTL sensor buses that modern SRAM FPGAs cannot drive without level shifting. Its 12,000 gates and 512 cells are sufficient for sequencers, counters, and bus-bridge glue logic, and the 320 MHz toggle capability comfortably covers typical industrial clock domains in the 10-50 MHz range. Because the antifuse fabric is non-volatile, the controller is operational the instant power is applied with no configuration device, improving system boot behavior and fault tolerance on machinery that must restart unattended after power dips.
おすすめ
5V Legacy Bus Bridge Logic
Bridging 5V legacy buses such as VME backplanes, ISA-style instrumentation interfaces, or 5V TTL peripheral ports to modern 3.3V subsystems is a natural fit for the A54SX08-2PQG208I. The device's I/O ring operates from a dedicated 4.75V to 5.25V rail while the core runs at 3.0V to 3.6V, so it absorbs 5V signals natively without external translators - a capability largely absent from current-generation FPGAs. The 130 user I/Os provide ample width for 16- or 32-bit data paths, and the deterministic antifuse routing delays simplify meeting fixed bus setup/hold budgets. Deploying the -2 speed grade keeps propagation margins generous; designers should budget the dual-rail power consumption and provide independent decoupling per the 54SX family datasheet power guidelines.
おすすめ
Telecommunications Line-Card Glue Logic
Telecom line cards frequently need a dependable FPGA for framing, multiplexing, and control-plane glue logic between physical-layer devices and backplane interfaces. The A54SX08-2PQG208I serves this role with 12,000 gates, 130 user I/Os, and a 320 MHz internal toggle ceiling that covers T1/E1 and STM-class clock domains. The antifuse fabric's fixed routing delays make timing sign-off deterministic, which matters in carrier equipment where redesign cycles are expensive, and the one-time-programmable configuration eliminates bitstream-upset concerns in electrically noisy central offices. With 0.35um CMOS, static power is modest compared with denser SRAM devices. For designs outgrowing 12K gates, the pin-compatible A54SX16-2PQG208I doubles capacity without a PCB respin.
おすすめ
Aerospace and Defense Secure Logic
Antifuse FPGAs like the A54SX08-2PQG208I are a mainstay in defense electronics because the one-time-programmable fabric cannot be read back, dumped, or remotely reconfigured - a significant advantage for design-ip protection compared with SRAM FPGAs that expose their bitstream. The industrial -40C to +85C grade covers many sheltered avionic and ground-based defense environments, and the non-volatile configuration means the logic is live at power-on with no external configuration PROM to fail or be attacked. At 12,000 gates the device handles secure sequencers, key-storage state machines, and anti-tamper supervisory logic. Microsemi (now Microchip) remains the incumbent supplier for this class of radiation-tolerant-heritage programmable logic, and design tools support remains available through the Libero suite.
おすすめ
Medical Instrumentation Control Logic
Bench-top and portable medical instrumentation - patient monitors, analyzers, and imaging peripherals - benefits from the A54SX08-2PQG208I's deterministic, configuration-free operation. The 12,000-gate capacity implements sensor interface sequencers, front-end timing controllers, and host interface glue logic, while the 130 user I/Os accommodate multi-channel sensor banks. Instant-on antifuse configuration removes boot-latency concerns in devices that must be ready immediately after power-up, and the industrial temperature range accommodates autoclave-adjacent and unconditioned clinical environments. Its 5V I/O rail also eases integration with older analog front-end components still supplied at 5V. Deterministic timing simplifies verification documentation required in regulated device development, reducing the validation burden compared with timing-drift-prone alternatives.
おすすめ
Test and Measurement Equipment
Prototype and production test equipment uses the A54SX08-2PQG208I as a configurable timing, triggering, and interface controller. The 320 MHz toggle rate and -2 speed grade support high-resolution edge generation, while the fixed antifuse routing delays give repeatable channel-to-channel skew - essential when measurement repeatability is the product. The 5V-tolerant I/O ring connects directly to legacy instrument buses and DUT interfaces, and the 130 user I/Os provide generous test-point fan-out. Because the configuration is non-volatile and instant-on, test fixtures power up deterministically between DUT cycles. Engineering teams can also exploit the same-package A54SX16-2PQG208I when test sequences grow beyond the 12K-gate budget, preserving the existing fixture PCB.

設計ノート
The A54SX08-2PQG208I requires two independent supplies: 3.0V-3.6V for the core and 4.75V-5.25V for the I/O ring. Provide separate regulators or filtered rails with local ceramic decoupling (typically 0.1 uF per supply pin pair plus bulk capacitance) on both domains. Because the I/O rail is 5V, verify your 5V regulator can source the dynamic I/O switching current of your design; 130 I/Os switching simultaneously can draw significant transient current. Estimated: with all 130 outputs toggling at 20 pF loads and 33 MHz, transient current can reach hundreds of milliamps - size bulk capacitance accordingly.
This is a one-time-programmable antifuse device: you cannot reprogram it in-system to fix logic bugs, unlike SRAM FPGAs. Complete thorough simulation and static timing analysis in Microchip Libero/Designer before committing to programming. Also note speed grade matters at purchase time - a '-1' or standard grade part cannot be made to meet '-2' timing. Order the '-2' suffix (as in A54SX08-2PQG208I) when your timing closure is near the limit, and stock spares since a failed programming cycle renders the device unusable.
Use the 208-pin PQFP (28x28 mm) land pattern from the Microchip 54SX family datasheet package section, which specifies 0.5 mm terminal pitch. Keep the 5V I/O domain traces separated from sensitive analog routing, and place decoupling capacitors within 2-3 mm of each supply pin. PQFP leads are delicate: avoid repeated reflow cycles and handle by the body. A thermal pad is not provided, so rely on lead-frame conduction; power dissipation is modest at 0.35um CMOS and rarely requires special thermal management in this gate count class.
