A54SX08-2FGG144 概要
An FPGA (Field-Programmable Gate Array) is a semiconductor device that implements custom digital logic through programmable interconnect and configurable logic blocks, sitting within the broader hierarchy of programmable logic devices alongside CPLDs and ASICs. The Actel SX family uses a sea-of-modules antifuse architecture: unlike SRAM-based FPGAs, its configuration is permanently set at programming time, giving it instant-on behavior, very low cryptographic vulnerability, and no external configuration memory requirement.
Key features include 320 MHz internal performance, 3.7 ns pin-to-pin clock-to-out timing, 0.1 ns input setup, and 0.25 ns clock skew, per the manufacturer datasheet. These timing figures enable single-chip integration of 66 MHz PCI-class designs with 100% resource utilization and 100% pin locking, a hallmark of the SX architecture.
Technically, the sea-of-modules architecture routes through antifuse elements, delivering ASIC-like speed and integration with deterministic timing. The device provides 111 user inputs and 111 user outputs in the 144-ball package, with fast pin-to-pin timing that simplifies system interfacing and enables parallel board-level design.
Typical applications include glue logic consolidation, bus interface and bridging (PCI and similar protocols), industrial control, aerospace/defense FPGA prototyping, and performance-intensive embedded control where instant-on, non-volatile configuration is required.
Design consideration: antifuse FPGAs are one-time programmable; functional changes require a new device, so verify the design in simulation thoroughly before programming. Power and I/O banking on the 3.3V/5V-tolerant I/O structure should be validated against the datasheet.
This page synthesizes verified distributor data, drop-in alternatives within the SX/SX-A families, and practical design notes not found in the manufacturer datasheet.

主な用途
A54SX08-2FGG144 の用途: 6 件s: 66 MHz PCI Bus Interface and Bridging, Glue Logic Consolidation, Industrial Control Systems, Aerospace and Defense Logic, Telecommunications Line-Card Logic, Test and Measurement Fixtures.
66 MHz PCI Bus Interface and Bridging
The A54SX08-2FGG144 fits 66 MHz PCI-class designs directly: its 320 MHz internal performance, 3.7 ns pin-to-pin clock-to-out, 0.1 ns setup, and 0.25 ns clock skew exceed PCI timing requirements with margin, enabling single-chip bridge or target/master logic per the manufacturer datasheet. In a bridge application, the device terminates the PCI bus in its I/O banks, implements arbitration or address decoding in its 512 logic cells, and benefits from antifuse instant-on configuration so the bus is available at power-up without configuration latency. Trade-off: antifuse programming fixes the logic permanently, so interface changes require new silicon.
おすすめ
Glue Logic Consolidation
Designers use the A54SX08-2FGG144 to replace dozens of 74-series devices, PALs, and GALs with one 8,000-gate antifuse FPGA. With 111 user inputs and 111 outputs on the 144-ball FBGA, the device absorbs address decoders, bus transceivers, wait-state generators, and interrupt controllers in a single package, cutting board area and BOM count. The SX sea-of-modules architecture supports 100% resource utilization with 100% pin locking, so consolidated logic can be finalized without repinning the PCB. Instant-on antifuse configuration ensures decoded chip-selects are valid immediately at power-up, which SRAM FPGAs cannot guarantee.
おすすめ
Industrial Control Systems
In industrial controllers, the A54SX08-2FGG144 provides deterministic, non-volatile logic for motor sequencing, I/O scanning, and safety interlocks. The 3.3V core with 5.0V-tolerant I/O lets it interface directly with legacy 5V TTL sensors and PLC I/O racks without level shifters, reducing component count and failure points. Antifuse configuration is immune to configuration corruption from power glitches or bit-flips, a meaningful reliability advantage on factory floors, and there is no bitstream to load at power-up. The 320 MHz performance ceiling leaves ample headroom for fast counter and PWM functions relative to typical industrial clock rates in the tens of MHz.
おすすめ
Aerospace and Defense Logic
Antifuse FPGAs like the A54SX08-2FGG144 are historically favored in aerospace and defense systems because the configuration is inherently radiation-tolerant against configuration upsets (no stored bitstream to corrupt), requires no external configuration memory, and powers up instantly with the design active. The 8,000-gate capacity suits custom bus interfaces, telemetry encoders, and command decoders, while 111 bidirectional-capable I/O cover backplane signaling. The Microsemi/Microchip lineage (same vendor as the RTAX space FPGAs) supports long-term procurement expectations. Designers should note the one-time-programmable constraint and budget engineering patches as new programmed devices rather than field reconfiguration.
おすすめ
Telecommunications Line-Card Logic
Telecom line cards use the A54SX08-2FGG144 for framing logic, backplane interfacing, and clock-domain bridging. The 320 MHz internal performance and 0.25 ns clock skew support high-frequency counters and synchronous logic, while fast pin-to-pin timing (3.7 ns clock-to-out) keeps backplane handshake paths inside tight system timing budgets. The non-volatile antifuse configuration means cards enumerate and pass traffic immediately upon shelf insertion - a real operational advantage in carrier equipment where SRAM FPGA configuration delay would stall system bring-up. Five-volt tolerant I/O simplifies mixing with legacy T1/E1 framer devices on older card designs.
おすすめ
Test and Measurement Fixtures
Bed-of-nails and functional test fixtures employ the A54SX08-2FGG144 as timing generators, pattern engines, and protocol responders. Instant-on antifuse operation means the fixture is live the moment power is applied - no configuration download delaying test throughput. The 320 MHz performance supports fast strobe generation, and 111 I/O in the compact 144-ball FBGA provides dense channel counts within a small footprint. Because the programmed design is fixed and physically unobservable through the antifuse array, test IP embedded in the fixture is inherently protected from extraction, unlike SRAM FPGA bitstreams which can be read from configuration memory.

設計ノート
The A54SX08-2FGG144 is a one-time-programmable antifuse FPGA. Unlike SRAM FPGAs, a design change after programming requires a new physical device. Complete full gate-level timing simulation and functional verification in Microchip Libero (or legacy Actel Designer) before committing silicon, and order spare programmed units for engineering patches. Budget 5-10% device overhead above required utilization since 100% packing, while achievable per the datasheet, leaves no margin for late ECOs.
Supply the FPGA core and I/O at 3.3V per the datasheet specification; the 5.0V-tolerant I/O supports legacy TTL interfaces without level translation, but input rise/fall and drive-current limits must still be checked against the SX family electrical tables. Decouple the 144-ball FBGA power balls with a network of 0.1 uF ceramic capacitors placed within 2-3 mm of the package, plus bulk 10 uF per rail. Simultaneous switching output (SSO) noise on the 111 user I/O should be managed by distributing ground return balls, per the SX family package guidelines.
The 144-ball FBGA (FGG144) requires fine-pitch BGA layout practice: via-in-pad or dogbone fanout with 0.3-0.5 mm via drills, controlled-impedance routing for high-speed pin-to-pin paths (3.7 ns clock-to-out assumes standard load per the datasheet), and attention to the BGA reflow profile - PBGA packages are moisture-sensitive, so bake and follow MSL floor-life rules from the device packing label. Keep clock routing short and matched to reduce the 0.25 ns clock-skew budget impact across the array.
