A54SX08-FG144 概要
An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a fabric of configurable logic blocks and interconnects that the designer programs after manufacturing. Within the programmable-logic hierarchy, the SX family occupies the high-speed antifuse segment: device -> FPGA -> antifuse FPGA -> Actel/Microchip SX family. Unlike SRAM-based FPGAs, antifuse FPGAs are non-volatile and configure once, which makes them resistant to configuration upset and unsuitable for repeated reprogramming.
Key features include 8,000 system gates organized as 512 cells in a sea-of-modules architecture, 111 user-input/output capability on the 144-ball package, I/O operation from 3.3V and 5V supply domains, and high-speed performance suited to state machines, bus bridging, and glue logic consolidation. The sea-of-modules architecture delivers routing efficiency and deterministic timing that simplify high-speed design closure.
Technically, the SX family is fabricated on a 0.35 um CMOS process and uses Actel's antifuse interconnect, which provides low on-resistance, low parasitic capacitance routing segments. This yields higher toggle rates and lower interconnect delay than contemporary SRAM routing switches, contributing to the family's 240 MHz class performance in performance-intensive applications.
Typical applications include industrial automation control, telecommunications and networking interface logic, military/aerospace systems requiring one-time-programmable non-volatile configuration, and embedded bridge or protocol-glue logic where 5V-tolerant I/O eases interfacing with legacy circuits.
Designers should note that antifuse devices are one-time programmable: the design must be finalized before programming, and design iterations require a new device. Choose the -I temperature-grade suffix (A54SX08-FG144I) for industrial -40C to +85C environments.

主な用途
A54SX08-FG144 の用途: 6 件s: Industrial Automation Control, Telecommunications Interface Logic, Military and Aerospace Systems, Legacy 5V Bus Bridging, Secure One-Time-Programmable Systems, Glue Logic Consolidation in Embedded Systems.
Industrial Automation Control
The A54SX08-FG144 fits industrial automation because its 5V-tolerant I/O (3.3V/5V operation) directly interfaces legacy PLC backplanes, sensor buses, and TTL-level control signals without external level shifters. Its 8,000 gates and 512 cells consolidate glue logic, address decoders, and state machines that would otherwise require multiple 74-series devices. The antifuse fabric provides deterministic, non-volatile configuration that survives power cycling without a configuration PROM, improving system boot time on factory floors. Used as a bridge between motor-controller logic and a higher-level CPU, its 240 MHz class toggle performance comfortably handles encoder-counting and interlock logic.
おすすめ
Telecommunications Interface Logic
Telecom line-card and backplane designs benefit from the A54SX08-FG144's high-speed sea-of-modules architecture, which delivers deterministic routing delays suited to framing, deserialization, and protocol-glue functions at line rates below its 240 MHz toggle class. The 111 user I/O in a compact 144-ball FBGA conserves board area on dense line cards, and 3.3V/5V I/O eases integration with legacy T1/E1 framer and backplane components. Because the antifuse configuration is non-volatile, remote equipment reboots without a boot device, improving carrier-grade availability. Designers should reserve I/O for JTAG boundary-scan test access during production.
おすすめ
Military and Aerospace Systems
The A54SX08-FG144 suits military and aerospace subsystems because antifuse configuration is inherently non-volatile and resistant to configuration upset, eliminating the external configuration storage that SRAM FPGAs require. Its 8,000-gate capacity handles payload sequencing, telemetry formatting, and bus-bridging logic in avionics boxes where board space and power are constrained. The 240 MHz class performance supports fast counters and parallel interfaces, while 3.3V/5V tolerance eases integration with mixed-voltage heritage designs common in legacy platforms. For higher-reliability programs, engineers often prototype on SX and migrate to the RTAX radiation-tolerant family while reusing RTL.
おすすめ
Legacy 5V Bus Bridging
Many installed systems still run 5V TTL and 5V CMOS buses that modern 3.3V-only devices cannot safely interface. The A54SX08-FG144's specified 3.3V/5V operation allows direct connection to these legacy rails, making it an ideal one-chip bridge between old and new subsystems during phased upgrades. Its 111 I/O can absorb dozens of discrete 74-series glue devices, reducing board area, power, and failure points. The 240 MHz class performance covers even aggressive bus turnaround timing. Antifuse one-time programming is acceptable here because bridge functions are fixed at design time, and configuration integrity over decades of service is a benefit rather than a limitation.
おすすめ
Secure One-Time-Programmable Systems
Designs with security requirements favor the A54SX08-FG144 because antifuse configuration cannot be read back or altered after programming, unlike SRAM FPGAs whose bitstreams are exposed during configuration loading. The 8,000-gate fabric is sufficient for authentication logic, secure key-handling state machines, and tamper-response glue logic in payment terminals, access-control systems, and licensed equipment. The 111 I/O in the 144-ball FBGA supports parallel interfaces to secure elements and host processors. With no external configuration PROM, there is no bitstream to intercept in transit, reducing the attack surface. Non-volatility also guarantees that no reprogramming occurs in the field.
おすすめ
Glue Logic Consolidation in Embedded Systems
Embedded board designers use the A54SX08-FG144 to consolidate address decoding, wait-state generation, interrupt aggregation, and memory-mapped glue logic into one 144-ball device. Compared with a handful of 5V and 3.3V PAL/GAL/74-series parts, the SX device provides recompilable (pre-programming) flexibility, deterministic timing from the antifuse fabric, and 240 MHz class speed margin. The 512-cell capacity typically absorbs the entire glue function of a microprocessor board, and 5V-tolerant I/O connects directly to legacy peripherals. Consolidation reduces BOM count, assembly cost, and inter-device skew, while the non-volatile configuration removes boot-time configuration delays from reset sequencing analysis.

主な差別化要因

- Higher timing headroom （vs A54SX08-2FGG144I)
設計ノート
Antifuse devices are one-time programmable. Unlike SRAM FPGAs, the A54SX08-FG144 cannot be erased or reprogrammed after configuration burn, so any post-silicon fix requires a new physical device. Budget unprogrammed spares into every build, freeze the design file before releasing devices to programming, and validate fully in the Libero/Designer simulation flow first. Also note the FG (leaded) plating may conflict with RoHS assembly profiles; select the FGG variant for lead-free reflow lines.
The 144-ball FBGA requires a carefully controlled land pattern and via-in-pad or dog-bone escape routing on fine pitch. Follow the Microchip SX datasheet package drawing for pad geometry, and verify ball-map pinout directly against the official datasheet before layout release - third-party ball maps for legacy Actel parts frequently contain errors. Plan JTAG programming access on the board, since antifuse programming and boundary-scan test both occur through the JTAG port; include a programming header or bed-of-nails access.
The SX family operates from 3.3V/5V supply domains per the verified data; exact per-rail current figures are not in the verified data and must be taken from the manufacturer datasheet power calculator. As a general practice, decouple each supply ball group with at least 0.1 uF ceramic capacitors placed close to the package, plus bulk capacitance per rail. Because antifuse fabric has no configuration inrush, power sequencing is simpler than SRAM FPGAs, but 5V-tolerant I/O should still not be driven before VDD is stable.
コンプライアンス情報
The FG144 suffix denotes standard (leaded) plating; the FGG144 variants are the lead-free option per Microchip naming convention. RoHS/REACH status for this specific suffix was not stated in verified data - verify with distributor compliance certificates before export-controlled or EU shipments.
