MPN： A54SX08-1TQG144 ✓ 啟用中A54SX08-1TQG144 概覽
A Field Programmable Gate Array (FPGA) is a semiconductor device containing a fabric of configurable logic blocks and programmable interconnects that designers configure in the field to implement custom digital circuits. Within the programmable logic hierarchy, the FPGA sits above CPLDs and PAL/GAL devices, offering higher gate counts and register-rich architectures. The Actel SX family is distinctive because it uses antifuse programming: one-time programmable connections that retain configuration through power cycles with no external configuration memory required.
Key features of the A54SX08-1TQG144 include the SX sea-of-modules architecture delivering 280 MHz-class performance, a 0.35 um CMOS process, 113 user I/O in a compact 144-TQFP footprint, and single-chip antifuse configuration that eliminates the boot-time and configuration-store complexity of SRAM FPGAs. The -1 speed grade denotes the standard speed bin of the SX family.
Technically, the SX family's sea-of-modules architecture provides a high ratio of usable registers to gates, which benefits high-speed state machines, bus interfacing, and glue-logic consolidation. Antifuse interconnect also yields low static power and inherent resistance to configuration upset, a property that made SX devices popular in industrial, communications, and aerospace-adjacent designs.
Typical applications include industrial control and automation, bridge and interface logic between incompatible bus standards, high-speed state machines, and redesign/obsolescence replacement of older ASIC or PAL/PLD circuits where a proven 5V-tolerant, non-volatile FPGA is preferred.
Design consideration: because the device is one-time programmable, verify the design fully in simulation before programming; plan I/O assignments against the 144-TQFP pinout early, and budget power for 3.3V core/5V-tolerant I/O conditions per the SX family datasheet.

典型應用
A54SX08-1TQG144 適用於 6 應用s: Industrial Control and Automation, Bus Bridge and Interface Logic, High-Speed State Machines, Obsolescence Redesign / ASIC Replacement, Communications Line Cards, Medical Instrumentation Control Logic.
Industrial Control and Automation
The A54SX08-1TQG144 fits industrial control and factory automation boards that need deterministic, instant-on logic without configuration boot delays. Its antifuse fabric powers up with the configured design already active - critical for safety interlocks and machine sequencing where a 100-500 ms SRAM-FPGA configuration load is unacceptable. The 3.3V core with 5V-compatible I/O bridges legacy PLC signal levels and 24V-domain buffer circuitry, and the 113 user I/O absorb parallel fieldbus, encoder, and I/O-module interfaces in the 20x20 mm TQFP footprint.
推薦
Bus Bridge and Interface Logic
As a bus bridge, the A54SX08-1TQG144 consolidates address decoding, bus sizing, wait-state generation, and protocol translation between legacy 5V TTL buses and modern 3.3V peripherals. The 280 MHz-class SX fabric easily meets PCI-era and microprocessor-interface timing, and the 800 ps-class propagation paths support fast combinatorial decode. Because the design is one-time programmable, the bridge logic is fixed and audit-friendly - an advantage in certified industrial equipment where post-deployment logic changes must be controlled.
推薦
High-Speed State Machines
The SX family's register-rich sea-of-modules architecture makes the A54SX08-1TQG144 well suited to fast finite-state machines: each logic module pairs a register with routing that supports 280 MHz-class toggle rates in the -1 grade. Typical uses include burst sequencers, memory controllers, and communications framing engines. The 768 logic cells provide enough capacity for multi-process state machines plus counters and comparators, while the antifuse interconnect delivers consistent, fixed timing that simplifies static timing sign-off across temperature and voltage corners.
推薦
Obsolescence Redesign / ASIC Replacement
The A54SX08-1TQG144 is a proven target for replacing discontinued PAL/GAL/PLD clusters and small gate-array ASICs. Its 0.35 um antifuse technology replicates the fixed-timing, non-volatile behavior of the devices it replaces, and the 144-TQFP surface-mount footprint suits legacy board respins. When a long-lifecycle industrial or defense-adjacent program must keep a PCB in production, re-implementing legacy glue logic in the A54SX08 preserves timing behavior while consolidating dozens of SSI/MSI parts into one certified device.
推薦
Communications Line Cards
In telecom and datacom line cards, the A54SX08-1TQG144 handles framing, clock-domain crossing, LED/alarms, and backplane interface logic. The 113 user I/O support dense parallel signaling across the 0.5 mm pitch TQFP, and 5V-tolerant inputs accept legacy backplane levels. Antifuse configuration contributes to low static power consumption, reducing line-card thermal budgets, and instant-on behavior ensures the card presents its management interface as soon as power is applied - useful in redundant, hot-swappable telecom architectures.
推薦
Medical Instrumentation Control Logic
Benchtop medical devices benefit from the A54SX08-1TQG144's deterministic power-up: front-end acquisition sequencing, sensor interface timing, and user-interface scanning run immediately without a configuration loader. Fixed antifuse timing supports repeatable measurement chains, and the 3.3V/5V supply flexibility simplifies mixed-voltage analog front-end integration. The one-time-programmable nature also supports configuration integrity requirements common in regulated equipment, since deployed logic cannot be silently altered in the field.

主要差異化特點
- Instant-on, no external configuration memory (對比SRAM FPGAs (Xilinx/Lattice equivalents))
- 5V-tolerant I/O in a modern FPGA (對比A54SX32-TQG144)
- Trade-off: one-time programmable (對比SRAM-based FPGAs)
設計說明
The A54SX08 is one-time programmable: once the antifuses are blown, the device cannot be erased or reprogrammed. Complete functional simulation and timing closure in the Microchip (Actel/Microsemi) design software, and verify the pin assignment file against the 144-TQFP pinout before submitting to programming. Budget one sacrificial device for programming-flow validation on new designs; a pin-mapping error discovered after programming wastes the part permanently.
The SX family operates from 3.3V/5V supply conditions per the family datasheet. Decouple each supply pin of the TQFP-144 with 0.1 uF ceramic capacitors placed within a few millimeters of the pin, and provide bulk 10 uF capacitance near the device. Because antifuse FPGAs draw little static current, dynamic switching activity dominates consumption; run the vendor power estimator with your utilization numbers before finalizing the supply rails.
The 144-TQFP footprint uses 0.5 mm lead pitch with leads on all four sides. Use a standard TQFP-144 land pattern per the manufacturer package drawing, keep trace widths adequate for 5V-tolerant I/O drive, and route high-speed state-machine or bus signals with short, direct traces to reduce stubs. Expose adequate thermal relief via ground vias around the die-attached center region for heat spreading, though dissipation at 8K-gate densities is modest.
