A54SX08-PLG84 概要
An FPGA (field programmable gate array) is a semiconductor device containing a matrix of configurable logic blocks (CLBs) interconnected by programmable fabric, allowing designers to implement custom digital circuits after manufacturing. Within the programmable logic hierarchy, the A54SX08 belongs to the Actel/Microsemi SX family of antifuse FPGAs - one-time-programmable (OTP) devices positioned below flash-based and SRAM-based FPGAs in system architecture. Antifuse programming gives the SX family inherent resistance to configuration bitstream readback, a key security and reliability trait in defense and industrial designs.
Key features include 8K equivalent system gates, 512 programmable cells organized into Cluster and FastConnect routing structures, 240 MHz maximum toggle performance on a 0.35 um CMOS process, and dual 3.3V/5V tolerant I/O operation. The 84-lead PLCC package uses a 1.27 mm pin pitch with J-bend terminations, offering a robust, reworkable surface-mount footprint popular in legacy board designs and space-constrained industrial assemblies.
Technically, the SX architecture combines C-cell (combinational) and R-cell (register) modules with dedicated flip-flops, delivering fast pin-to-pin timing that simplifies system interface design and supports parallel board-level development. The antifuse interconnect adds less parasitic capacitance than SRAM switches, contributing to the family's speed and low dynamic power.
Typical applications include glue logic consolidation, industrial control, military/aerospace subsystems, communications line cards, and legacy board sparing - anywhere a small, secure, one-time-programmable FPGA in a through-hole-rework-friendly PLCC is required.
Design consideration: because antifuse FPGAs are OTP, verify your netlist thoroughly in simulation and via the Libero/Designer tools flow before programming; there is no in-system reconfiguration as with SRAM FPGAs.

主な用途
A54SX08-PLG84 の用途: 6 件s: Glue Logic Consolidation, Industrial Control Systems, Military and Defense Subsystems, Communications Line Cards, Legacy Board Spares and Obsolescence Management, Test and Measurement Equipment.
Glue Logic Consolidation
The A54SX08-PLG84 excels at replacing dozens of 74-series TTL/CMOS chips with a single 8K-gate antifuse FPGA. Its 69 user I/O and fast, deterministic pin-to-pin timing (240 MHz class) let designers merge address decoders, bus transceivers, state machines, and interrupt controllers into one device, cutting board area and BOM count. Because the antifuse fabric is programmed once, the consolidated logic behaves like an ASIC on power-up with no configuration controller or boot flash required - a decisive advantage over SRAM FPGAs in cost-sensitive legacy boards. The 84-PLCC package also suits older two-sided PCB layouts that cannot accommodate fine-pitch BGAs.
おすすめ
Industrial Control Systems
In PLC I/O modules, motor-control interfaces, and factory automation backplanes, the A54SX08-PLG84 provides deterministic, instantly-ready logic at 3.3V/5V levels - directly compatible with legacy 5V industrial buses without level shifters. The industrial-grade A54SX08-PLG84I variant covers extended temperature, and the one-time-programmable antifuse configuration survives power cycles and ESD events with no configuration reload, improving uptime. The robust 84-PLCC J-lead package withstands rework and vibration better than fine-pitch alternatives, and its 1.27 mm pitch is compatible with standard wave-and-reflow mixed-technology assembly used in industrial hardware.
おすすめ
Military and Defense Subsystems
The SX family is a long-standing choice in defense electronics because the antifuse configuration is non-volatile and cannot be read back as a bitstream, protecting firmware IP and defeating configuration-upset concerns in ground-based military hardware. The 8K-gate A54SX08-PLG84 implements bus interfaces, telemetry formatting, and secure-boot support logic. Its instant-on behavior meets the power-up immediacy requirements of weapon and radar subsystems, and Microchip's proven longevity program supports long program lives. For radiation-exposed flight paths, Microchip's RTAX-S rad-hard family (e.g., RTAX1000SL) provides the migration path.
おすすめ
Communications Line Cards
Telecom and datacom line cards historically used SX FPGAs for framing, error detection, and backplane interface logic. The A54SX08-PLG84's 240 MHz toggle capability and FastConnect routing handle counters, CRC engines, and protocol state machines at legacy T1/E1 and backplane rates. The 3.3V/5V tolerant I/O connects directly to 5V TTL backplane signals common in installed telecom chassis, and the antifuse fabric adds no configuration latency at card slot-in. The 84-PLCC footprint also matches the through-hole-repair practices of telecom field service, simplifying maintenance of deployed racks.
おすすめ
Legacy Board Spares and Obsolescence Management
Boards designed in the late 1990s and 2000s around the A54SX08 in PLCC-84 continue in service across industrial, medical, and defense fleets. The A54SX08-PLG84 serves as the exact-form-fit-function spare for these repairs, and its same-footprint variants (A54SX08-PLG84I, -2PLG84, -2PLG84I) give buyers alternate temperature and speed grades when commercial grade is exhausted. Because antifuse programming is permanent and the design tools (Microchip Libero/Designer) still support the SX family, a spare device can be programmed from archived netlists years after the original build, keeping legacy systems fieldable without board redesign.
おすすめ
Test and Measurement Equipment
Bench instruments, ATE fixtures, and interface adapters benefit from the A54SX08-PLG84's instant-on, one-time-programmed logic for timing generators, trigger logic, and pattern capture. The 240 MHz-class performance covers counter and timing-reference duties, while 69 I/O with 5V tolerance interfaces directly with legacy instrument buses and test points. Deterministic antifuse routing gives repeatable propagation delays fixture-to-fixture - valuable when test correlations depend on consistent timing. The PLCC-84 socket-compatible package even allows socketed programming and swap in bench prototypes, something BGA-based FPGAs cannot offer.

設計ノート
The A54SX08-PLG84 is one-time programmable: after antifuse programming there is no reconfiguration path. Complete functional simulation, timing closure, and design-rule checks in the Microchip Designer (Libero SoC) flow before releasing the programming file to production. Keep archived programming (STAPL/FUSE) files together with your netlist and tool version records, since re-programming a mis-programmed part requires physically replacing the device on the board.
The 84-PLCC package uses a 1.27 mm J-lead pitch on a standard square land pattern; most CAD libraries' PLCC-84 footprints apply directly. Because PLCC parts can be socketed, decide early whether the board uses a socket (eases programming and field replacement but adds contact resistance and reliability risk in vibration) or direct SMD attachment (better electrical integrity). Decouple each VCC pin pair with 0.1 uF ceramics placed within a few millimeters of the package, plus bulk 10 uF near the supply entry.
The SX family operates with 3.3V core/5V-tolerant I/O configurations per the 54SX datasheet; confirm the exact supply scheme for your I/O bank before routing. Estimated: at 240 MHz with a large portion of the 512 cells toggling, dynamic current remains modest on the 0.35 um process, but verify with Designer's power estimator for your netlist rather than assuming. Ensure power-up monotonicity per datasheet requirements - antifuse FPGAs need no configuration device, but they do need clean, in-spec ramps at the pins.
