A54SX08-FGG144I 概要
An FPGA (field programmable gate array) is a semiconductor device containing a fabric of programmable logic blocks and interconnects that the designer configures after manufacturing. Within the programmable logic hierarchy, the FPGA sits above CPLDs and below ASSPs/ASICs in integration, and the SX family belongs to the antifuse-based, nonvolatile class of FPGAs, meaning the configuration is permanently set at programming time and is retained without a configuration PROM or boot sequence.
Key features of the A54SX08-FGG144I include a sea-of-modules architecture delivering up to 320 MHz internal toggle performance, 3.7 ns clock-to-out (pin-to-pin), 0.1 ns input setup, and 0.25 ns clock skew, making it suitable for high-speed glue logic, state machines, and interface bridging. The device is fabricated on a 0.35 um CMOS process and supports both 3.3 V and 5 V operating supply voltages, which simplifies integration into legacy 5 V industrial backplane systems alongside modern 3.3 V logic.
The SX family's antifuse architecture provides two significant engineering advantages over SRAM FPGAs: the configuration is inherently nonvolatile and secure, and there is no need for external boot memory, reducing board area and configuration time to zero. Logic is implemented in efficient combinational and sequential modules that allow single-chip integration of functions previously requiring multiple CPLDs, with the datasheet highlighting 66 MHz PCI integration as a single-chip solution.
Typical applications include industrial automation control, 66 MHz PCI interface bridging, telecommunications line-card glue logic, military/aerospace subsystems requiring nonvolatile configuration, and obsolescence-mitigation redesigns of legacy Actel-based designs.
Designers should note that antifuse FPGAs are one-time programmable; a change in the netlist requires a new device, so reserve sufficient I/O margin and simulate thoroughly before committing. The 144-FBGA package requires careful ball-map verification against the latest Microchip datasheet before layout.

主な用途
A54SX08-FGG144I の用途: 6 件s: 66 MHz PCI Interface Bridging, Industrial Automation Control, Telecommunications Line Cards, Aerospace and Defense Subsystems, Legacy Redesign and Obsolescence Mitigation, Test and Measurement Instrument Logic.
66 MHz PCI Interface Bridging
The A54SX08-FGG144I is explicitly positioned by Microchip as a single-chip 66 MHz PCI solution, replacing multi-CPLD PCI implementations. Its 3.7 ns pin-to-pin clock-to-out, 0.1 ns input setup, and 0.25 ns clock skew provide the timing headroom required by the 66 MHz PCI specification, while 111 user I/O accommodate complete 32-bit or 64-bit PCI signal groups plus auxiliary bridge logic. In a typical topology, the FPGA sits between a host backplane and application-specific peripherals, implementing target/master state machines, arbitration assist, and address decoding in the 512-cell fabric. Because the antifuse configuration is nonvolatile, the PCI interface is functional immediately at power-up with zero configuration latency - a distinct advantage over SRAM FPGAs in systems where the bus must respond within milliseconds of reset release. Verify final timing against the chosen speed grade and Microchip's PCI reference designs.
おすすめ
Industrial Automation Control
Industrial programmable logic controllers, motor-control interface cards, and factory automation modules benefit from the A54SX08-FGG144I's industrial -40C to +85C rating and 3.3 V / 5 V dual supply compatibility, which allows direct interfacing with legacy 5 V sensor and actuator logic as well as modern 3.3 V microcontroller domains. The 8,000-gate fabric integrates sequencers, encoders, PWM generators, and interlock logic that previously required several CPLDs, reducing board area and BOM count. Its antifuse one-time-programmable configuration is immune to configuration upsets from electrically noisy industrial environments and eliminates the external configuration flash that could be a single point of failure. Designers typically combine the FPGA with a microcontroller or with Microchip's analog monitoring parts, keeping control algorithms in firmware and hard real-time sequencing in the deterministic SX fabric with its 240 MHz internal performance.
おすすめ
Telecommunications Line Cards
Telecom line-card designs use the A54SX08-FGG144I for glue logic, framing-interface support, backplane handshaking, and LED/status sequencing where deterministic, immediately available logic is mandatory. The 144-ball FGG144 package with 1 mm ball pitch fits the high-density surface-mount layouts typical of carrier equipment, and the 111 user I/O connect to backplane connectors, framer devices, and alarm buses. The 0.25 ns clock skew specification supports clean distribution of a common line-card clock across multiple synchronous domains. Nonvolatile antifuse configuration ensures the card presents its backplane handshake immediately upon slot insertion, which simplifies hot-swap state sequencing. Designers should decouple each supply ball pair and verify the 3.3 V I/O levels against backplane standards in use. The same footprint accommodates the faster A54SX08-2FGG144I if timing margins tighten during system bring-up.
おすすめ
Aerospace and Defense Subsystems
Actel/Microsemi SX-family FPGAs have a long heritage in aerospace and defense electronics, where the A54SX08-FGG144I's antifuse technology offers intrinsic design security (the configuration cannot be read back), tolerance to radiation-induced configuration upsets compared with SRAM fabrics, and zero boot-time availability - attributes valued in satellite payloads, avionics sensor interfaces, and secure communications equipment. The single-chip integration of 8,000 gates replaces multiple configurable devices, reducing points of failure in mission-critical assemblies. The 5 V-tolerant dual-supply operation eases integration with legacy mil-spec 5 V logic. For new space-grade designs, Microchip's RTAX radiation-tolerant family continues the same architectural lineage; for flight programs already qualified on SX silicon, the FGG144I remains a sourcing-stable choice through Microchip's long-lifecycle policy. Verify program-specific screening requirements before selection.
おすすめ
Legacy Redesign and Obsolescence Mitigation
A large installed base of Actel SX-based boards requires maintenance spares and redesign bridges. The A54SX08-FGG144I serves as the continuation part for designs originally built with Actel-branded A54SX08 devices, since Microchip maintains the same silicon and the original 54SX datasheet. Its 3.3 V / 5 V operation and FBGA footprint match boards laid out in the late 1990s and 2000s, allowing drop-in refresh of logic that has no equivalent in modern low-voltage FPGA families without level-shifting redesign. When combined with the same-footprint commercial and -2 speed-grade variants, sourcing teams can qualify a single footprint across multiple build temperatures and timing budgets. Engineers migrating away from the platform should evaluate the SX-A family (A54SX08A-FGG144I) as the nearest same-package step, or Microchip's IGLOO/PolarFire families for a functional (non-pin-compatible) redesign path.
おすすめ
Test and Measurement Instrument Logic
Bench and rack instruments use the A54SX08-FGG144I for timing chains, trigger logic, counter front-ends, and bus interfacing where deterministic sub-nanosecond-class clock skew (0.25 ns) and 240 MHz internal performance are more important than logic density. The 512-cell fabric handles trigger state machines and prescalers that discrete 74-series glue logic cannot integrate within the same power and area budget. Nonvolatile configuration means the instrument is logic-functional the instant power is applied - no configuration controller, boot PROM, or configuration watchdog is required, improving MTBF and simplifying safety certification. The 111 user I/O connect front-panel connectors, ADC data buses, and IEEE-488 or UART control interfaces. Designers should allocate spare I/O for diagnostics and use the -2 speed grade variant where trigger-path timing margins are tight.

設計ノート
The SX family is antifuse-based and one-time programmable: a netlist change requires physically new devices, unlike SRAM FPGAs. Freeze the design through full simulation and timing verification before ordering production quantities, and order a small pilot lot first. Budget programming service lead time if you do not have in-house antifuse programming capability. Also confirm your design tools (Microchip Libero or legacy Actel Designer) support the original SX family before committing to new development on this platform.
The device supports 3.3 V and 5 V supplies. When driving 5 V loads, verify per-bank I/O standards in the datasheet and ensure ground bounce on simultaneously switching outputs stays within budget - with 111 user I/O, group SSO-capable pins and use the recommended number of ground balls per bank. Decouple each VCC/VCCA ball pair with 0.1 uF ceramics placed within 2-3 mm of the ball, plus bulk 10 uF per supply domain. VCCA ( PLL/analog supply, if used) requires the cleanest rail per manufacturer application guidance.
The 1 mm-pitch 144-FBGA requires a controlled reflow profile; follow the latest Microchip/JEDEC-type soldering profile for BGA packages and inspect via X-ray, since collapsed balls hide solder opens. Via-in-pad with filled vias is acceptable for escape routing on 4+ layer boards; otherwise use dog-bone escapes on the outer two ball rows and route inner rows on inner layers. Confirm ball coordinates against the official 54SX datasheet pin table - never copy ball maps from third-party CAD libraries without datasheet verification.
With 3.7 ns pin-to-pin clock-to-out and 0.25 ns clock skew, timing closure for 66 MHz PCI and similar interfaces depends heavily on place-and-route quality. Enable timing-driven placement, constrain all clock domains explicitly, and review the static timing report against the speed-grade tables in the Microchip 54SX datasheet. For high-fanout clocks, use the dedicated routing resources identified in the datasheet rather than general interconnect to keep skew at the specified 0.25 ns level.
