A54SX16A-2TQG144 Обзор
An FPGA (Field Programmable Gate Array) is a semiconductor device containing a matrix of configurable logic blocks interconnected by programmable routing, allowing designers to implement custom digital circuits after manufacturing. Within the programmable logic hierarchy, the A54SX16A belongs to the sea-of-modules antifuse FPGA category: FPGA -> programmable logic IC -> CMOS digital IC. Microchip (formerly Microsemi, originally Actel) positions the SX-A family as a low-cost, single-chip integration platform.
Key differentiating features include the 0.25 um CMOS antifuse technology, which makes configuration permanent and inherently resistant to configuration readback attacks, a single 2.5V supply (2.25V to 2.75V tolerance), speed grade -2 timing with typical combinatorial CLB delay around 1 ns, and non-volatile programming that eliminates the external boot flash and configuration bitstream required by SRAM FPGAs.
The SX-A architecture arranges its 924 logic cells (1,452 CLBs) in a sea-of-modules fabric with dedicated routing resources, supporting both combinatorial and registered functions with clock frequencies approaching 294 MHz. Because the antifuse interconnect is programmed once at the factory-programmable stage or during board assembly, standby power is very low and there is no configuration uptime penalty at power-up.
Typical applications include industrial control and automation glue logic consolidation, aerospace and defense designs requiring design security, telecommunications line-card support logic, and medical instrumentation control circuits. The 113 user I/O supports 2.5V and 3.3V-tolerant signaling common in these domains.
Design consideration: antifuse FPGAs are one-time programmable; finalize the design and verify timing in simulation before committing devices, and budget for the programmer and programming socket during production planning.

Типичное применение
A54SX16A-2TQG144 подходит для 6 применениеs: Industrial Control and Automation, Aerospace and Defense Secure Logic, Telecommunications Line Cards, Medical Instrumentation Control, Test and Measurement Equipment, Legacy System Sustainment and Obsolescence Bridging.
Industrial Control and Automation
The A54SX16A-2TQG144 consolidates PLC I/O decoding, state machines, and bus glue logic into a single 24,000-gate antifuse FPGA. Its 113 user I/O at 2.5V/3.3V signaling interfaces directly with industrial sensor lines and backplane buses, while the 294 MHz toggle rate at speed grade -2 comfortably covers counter and encoder-processing tasks. Because configuration is non-volatile antifuse, the controller powers up instantly with no boot flash or configuration controller, improving system availability in factory equipment. Place it between the microprocessor local bus and field I/O with 0.1 uF decoupling per supply pin; the one-time-programmable fabric also prevents unauthorized design extraction on the factory floor.

Aerospace and Defense Secure Logic
Antifuse FPGAs are a long-standing choice for defense electronics because the A54SX16A-2TQG144's configuration lives in permanent antifuse elements with no external bitstream storage, eliminating configuration readback and bitstream interception risk. The SX16A provides 16,000 usable gates for interface bridging, protocol wrappers, and trusted boot glue logic, with military-temperature sibling A54SX16A-1TQG144M available on the same footprint for extended environments. Design flow uses Microchip Libero/Designer with verification in simulation before programming, since antifuse devices cannot be reprogrammed. Budget programming socket logistics early; the 144-pin TQFP's 1.4 mm profile also suits conduction-cooled board stacks.
Рекомендуется
Telecommunications Line Cards
On telecom line cards, the A54SX16A-2TQG144 serves as system glue logic: address decoding, interrupt aggregation, framer-to-backplane multiplexing, and LED/status control. Its 924 logic cells at speed grade -2 support 294 MHz internal toggling, well above E1/T1 and ST-BUS clock domains, while the single 2.5V rail with 2.25V-2.75V tolerance simplifies power tree design alongside 2.5V DSP and PHY cores. The 113 user I/O absorb the many point signals typical of line-card monitoring, and the non-volatile fabric removes the configuration controller and boot PROM that SRAM FPGAs require, reducing BOM cost per card in mid-volume production.
Рекомендуется
Medical Instrumentation Control
Diagnostic and laboratory instruments use the A54SX16A-2TQG144 for deterministic front-end sequencing, gain-switch control, and communication bridging between analog front ends and host processors. The 16,000 usable gates implement safety interlock state machines with predictable, single-chip behavior, and the antifuse configuration ensures the instrument always starts in a known-good bitstream, an audit-friendly property for controlled medical equipment. Low static power of the 0.25 um CMOS fabric keeps standby draw low for battery-backup scenarios. Use 0.1 uF plus 10 uF decoupling at the 2.5V rail and route the 113 I/O with matched lengths on timing-critical front-end clocks.
Рекомендуется
Test and Measurement Equipment
Bench and automated test instruments deploy the A54SX16A-2TQG144 as pattern generators, timing controllers, and fixture-interface logic. Speed grade -2 timing with roughly 1 ns combinatorial CLB delay supports fast handshaking to DUT interfaces, while 113 user I/O map onto relay drivers, mux select lines, and pass/fail indicators without external PAL glue. The one-time-programmable fabric guarantees the test station's stimulus logic cannot be corrupted between calibration cycles, supporting measurement repeatability. When instrument revisions demand more capacity, the pin-compatible A54SX32A-TQG144A on the same 144-pin TQFP footprint enables an upgrade without PCB respin.

Legacy System Sustainment and Obsolescence Bridging
The A54SX16A-2TQG144 is a practical consolidation vehicle for sustaining mature platforms: it replaces multiple 7400-series, PAL, and GAL devices whose packages are disappearing from catalogs. One 24,000-gate antifuse FPGA absorbs dozens of legacy SSI/MSI functions, cutting board area and inventory count while preserving the platform's interface timing, since speed grade -2 covers 294 MHz toggling far above legacy bus rates. Microchip (formerly Actel/Microsemi) continues to support the SX-A family with Libero design software and authorized distribution stock, giving long-lifecycle programs a stable second source for legacy logic migration with RoHS-compliant, lead-free TQFP-144 packaging.

Заметки по проектированию
The A54SX16A-2TQG144 operates from a single 2.5V rail specified at 2.25V to 2.75V. Provide 0.1 uF ceramic decoupling at each supply pin pair plus at least one 10 uF bulk capacitor per device. Antifuse FPGAs draw very low static current, but dynamic current scales with clock frequency and switching activity, so size the regulator for worst-case design utilization rather than the die's minimum. Because many user I/O tolerate 3.3V signaling, verify each bank's voltage against the SX-A datasheet I/O table before connecting 3.3V drivers to avoid overstress.
This device is one-time programmable: once antifuses are burned, the part cannot be erased or reused. Complete functional simulation, timing analysis, and pin assignment sign-off in Microchip Libero/Designer before submitting devices to programming. Keep the pin-report file from the software under version control, since the 113 user I/O assignments are design-specific and must match the PCB netlist exactly. Also note that most pins are user-definable, so the fixed-pin list (power, ground, programming, test) in the datasheet is the only universal reference for PCB layout.
The 144-pin TQFP has a 0.5 mm pin pitch and 1.4 mm body height. Use solder-mask-defined pads per the datasheet land pattern and route escape traces at 0.15-0.2 mm width with via-in-pad avoided under the die center. For timing-critical buses above 50 MHz, length-match I/O groups and keep stubs short; TQFP leads add roughly 1-2 nH of parasitic inductance per pin, which matters for simultaneous-switching noise on the 113 I/O. A solid ground plane under the device plus one decoupling capacitor per pair of supply pins controls ground bounce effectively.
Mouser lists this part as non-stocked with a 12-week factory lead time as of 2026-09-03. For production builds, order ahead or qualify a same-footprint backup such as the A54SX16A-1TQG144I (industrial temperature) or A54SX32A-TQG144A (higher density) early in the project. When qualifying a speed-grade substitution, re-run timing analysis: the -1 grade is slower than the -2 grade of this part, and designs near 294 MHz timing closure at -2 may fail at -1.
