Typical Applications

A54SX16A-1TQG144 is suitable for 6 applications: Industrial Control and Automation, Secure and Defense Electronics, Glue Logic Consolidation on Legacy Boards, Communications and Networking Interface Bridging, Aerospace and Avionics Subsystems, Medical Instrumentation Control Logic.

🏭

Industrial Control and Automation

The A54SX16A-1TQG144 fits industrial controllers because its -40C to +125C operating range and 2.25V to 5.25V wide supply tolerance handle electrically noisy factory environments with unstable rails. Its 24,000 system gates and 113 user I/O integrate PLC I/O interfaces, state machines, and bus bridges that would otherwise require dozens of discrete TTL/CMOS devices, reducing BOM count and board area. Because the antifuse configuration is non-volatile, the logic is fully operational the instant power is applied - critical for safety interlocks and machine-control sequencing that cannot wait for configuration download. Design the I/O with standard industrial buffering and verify timing at worst-case -1 speed grade across temperature.

🔒

Secure and Defense Electronics

Antifuse FPGAs are favored in defense and secure systems because the programmed interconnect cannot be read back, cloned, or corrupted by radiation-induced configuration upsets - the A54SX16A-1TQG144 stores its function permanently in blown antifuse links rather than in an SRAM bitstream. The 24K-gate density suits secure communications glue logic, bus interfaces, and custom control cores, while the 144-pin TQFP supports conformally coated, board-space-constrained modules. Its one-time-programmable nature also eliminates the external flash that would otherwise be an attack surface. For temperature-extended programs, use the A54SX16A-1TQG144I or -M graded drop-ins on the identical footprint.

🔧

Glue Logic Consolidation on Legacy Boards

The A54SX16A-1TQG144 is a natural replacement for boards assembled from many discrete 74-series TTL/CMOS devices: its fine-grained C-cell/R-cell sea-of-modules architecture maps address decoders, wait-state generators, bus transceivers, and interrupt controllers efficiently, and 16,000 typical usable gates cover most glue-logic clusters with headroom. Consolidating to one 144-pin TQFP cuts board area, assembly cost, and failure points. Because the antifuse device requires no configuration ROM, it drops into legacy power-up sequencing without firmware changes. Verify 5V-tolerant I/O requirements against the SX-A datasheet I/O specifications before replacing mixed-voltage TTL circuitry.

🌐

Communications and Networking Interface Bridging

With system performance up to 263 MHz and deterministic antifuse routing delays, the A54SX16A-1TQG144 implements protocol bridges, serial-interface controllers, and backplane glue logic in networking line cards and telecom equipment. The deterministic timing of the SX-A architecture simplifies meeting fixed-latency interface requirements that are difficult with SRAM FPGA routing variability. Its 113 user I/O support multiple parallel data paths, and instant-on operation means links are established at power-up with no configuration delay. Use the -2 speed grade drop-in A54SX16A-2TQG144 if your timing closure is marginal at the -1 grade.

✈️

Aerospace and Avionics Subsystems

The A54SX16A family is widely used in aerospace subsystems - avionics data buses, sensor interfaces, and instrument control - because antifuse configuration is immune to configuration memory single-event upsets and the part operates to +125C. The 144-pin TQFP with 1.4 mm profile suits COTS-based avionics boards where reflow assembly and low height matter. One-time programmability supports configuration control and configuration-management audits common in aerospace programs. Programmed once and verified, the device behaves as a fixed-function ASIC-like component, simplifying qualification. Select M- or I-grade variants for graded programs; all share the TQG144 footprint.

💊

Medical Instrumentation Control Logic

Medical diagnostic and monitoring equipment benefits from the A54SX16A-1TQG144's combination of instant-on deterministic logic, low static power from the 0.25 um CMOS antifuse process, and RoHS3-compliant assembly. Typical uses include sensor-interface sequencing, data-acquisition timing controllers, and front-panel/bus interfaces in analyzers and imaging subsystems where the logic must be operational before software boots. The one-time-programmable configuration supports the change-control rigor required in regulated medical device manufacturing - once released, the logic cannot drift or be accidentally altered. Consolidating discrete logic into one device also improves reliability statistics used in device risk assessments.

What are the key specifications of A54SX16A-1TQG144 that engineers should know?
The A54SX16A-1TQG144 is a Microchip (Actel/Microsemi) SX-A antifuse FPGA with 24,000 system gates (about 16,000 typical usable gates), 1452 logic cells, 113 user I/O, and a maximum system frequency of 263 MHz. It is fabricated in 0.25 um CMOS, operates from a 2.25V to 5.25V supply across -40C to +125C, and comes in a 144-pin TQFP (TQG144, 20x20 mm, 1.4 mm height) package. According to distributor listings, it is RoHS3 compliant, active, and supplied in trays.
What is the price of A54SX16A-1TQG144?
As of 2026-09-03, A54SX16A-1TQG144 is listed by Mouser at $130.62 each in 60-piece quantity with a 12-week lead time on non-stocked orders. XAIPART pricing starts at approximately $141.20 for single units and drops to roughly $118.50 at 1000 pieces. Because this is a mature Microsemi-derived FPGA, street pricing varies significantly between distributors; requesting quantity quotes from multiple sources is recommended for volume buys.
Where to buy A54SX16A-1TQG144 online?
A54SX16A-1TQG144 can be purchased from DigiKey (ships today per their listing), Mouser (60-piece minimum, $130.62 as of 2026-09-03), Octopart-brokered distributors, Jotrin Electronics, OnlineComponents.com, and Microchip USA. XAIPART also offers this part with tiered pricing and drop-in alternative cross-references. For guaranteed authenticity of this mature antifuse FPGA, buy from authorized distributors or verified brokers with date-code and provenance guarantees.
What is the lead time and stock status for A54SX16A-1TQG144?
Availability is mixed across distributors as of 2026-09-03: DigiKey reports in-stock inventory that ships today, while Mouser lists the part as non-stocked with a 12-week manufacturer lead time at a 60-piece minimum. Microchip USA notes a 10-week manufacturer lead time for related variants. This split indicates authorized stock is limited, so for production quantities you should secure allocation early or evaluate drop-in alternatives such as A54SX16A-1TQG144I or A54SX16A-2TQG144.
What is the difference between A54SX16A-1TQG144 and A54SX16A-1TQG144I?
The only difference is the temperature grade suffix. The A54SX16A-1TQG144 is the commercial/standard grade, while the I-suffix A54SX16A-1TQG144I is the industrial grade device. Both share the identical -1 speed grade, 24,000-gate SX-A die, 113 user I/O, and 144-pin TQFP package, so they are pin-to-pin drop-in replacements on the same PCB footprint. Choose the I-grade for extended industrial temperature environments; confirm the exact temperature range values on the manufacturer datasheet before finalizing.
Is A54SX16A-2TQG144 a drop-in replacement for A54SX16A-1TQG144?
Yes, the A54SX16A-2TQG144 is a drop-in replacement for A54SX16A-1TQG144. Both use the same 144-pin TQFP (TQG144) package with the same SX-A 24K-gate die and pinout. The only difference is speed grade: the -2 suffix is a faster speed grade than the -1, so any design meeting timing on a -1 device will meet timing on a -2 device. The reverse is not guaranteed - a design compiled for -2 timing may fail on a -1 part. Pricing and availability differ between grades.
What is the best alternative brand equivalent for A54SX16A-1TQG144 (cross-brand)?
There is no verified cross-brand drop-in equivalent for the A54SX16A-1TQG144. Its 24K-gate antifuse architecture, 144-pin TQFP footprint, and pinout are proprietary to Actel/Microsemi/Microchip; competitors such as Xilinx, Altera (Intel), and Lattice offered SRAM-based FPGAs of similar density (for example XC4000-class parts), but none are pin-to-pin compatible, and SRAM devices require external configuration memory. Verified cross-reference searches returned only Microchip same-family alternates, so a cross-brand replacement would require a PCB redesign.
When should I choose A54SX16A over an SRAM-based FPGA?
Choose the A54SX16A when you need instant-on operation without external configuration memory, high design security (antifuse data cannot be read back), low static power, and permanent one-time-programmable configuration for glue logic consolidation. Choose an SRAM FPGA instead when you need in-field reconfigurability, higher density, or embedded hard blocks such as DSP slices and RAM. For fixed-function legacy board designs, industrial control, and defense applications where reprogramming is a liability, the antifuse A54SX16A remains the stronger choice.
Is A54SX16A-1TQG144 suitable for industrial automation applications?
Yes, the A54SX16A-1TQG144 is well suited to industrial automation. It operates from -40C to +125C, tolerates a wide 2.25V to 5.25V core supply range, and its antifuse configuration powers up instantly with full function - valuable in factory controllers and motor-control boards that must be operational at power-on. With 24,000 system gates and 113 user I/O, it can integrate bus interfaces, state machines, and glue logic that would otherwise require dozens of discrete TTL/CMOS devices, reducing board area and component count.
What is the best drop-in replacement for A54SX16A-1TQG144?
The best drop-in replacement is the A54SX16A-1TQG144I (industrial temperature grade), which shares the identical 144-pin TQFP footprint, pinout, die, and -1 speed grade. Other verified drop-ins include A54SX16A-1TQG144M, A54SX16A-2TQG144, A54SX16A-2TQG144I, and A54SX16A-TQG144A. All use the same TQG144 package; only temperature grade and speed grade vary. Select based on your required operating temperature and timing margin, then verify speed-grade timing in your implementation toolchain.
Where to download A54SX16A-1TQG144 datasheet PDF?
The A54SX16A datasheet PDF is available from the Microchip Technology product page at microchip.com/en-us/product/A54SX16A, and archived Actel/Microsemi SX-A family datasheet PDFs are hosted on aggregator sites such as Alldatasheet (the SX-A family document is approximately 108 pages, 720 KB per aggregator metadata). Always download the latest revision from Microchip directly, as the original Actel document dates from 2007 and Microchip may have reissued compliance or ordering information since.
Where can I find the A54SX16A-1TQG144 pinout?
The complete 144-pin TQFP pinout for A54SX16A-1TQG144 is provided in the SX-A family datasheet from Microchip Technology, in the pin description and package tables for the TQG144 package. Because exact VCC/GND, I/O bank, and dedicated input pin assignments must match the manufacturer document precisely, refer to the official datasheet rather than third-party pinout summaries. The physical package is a 20x20 mm, 1.4 mm-tall 144-lead TQFP with gull-wing leads on 0.5 mm pitch.
How do I program the A54SX16A-1TQG144 and what tools are used?
The A54SX16A-1TQG144 is a one-time-programmable antifuse FPGA programmed using Actel/Microsemi (now Microchip) silicon sculpting programmers such as the Silvio/FP4-class programming hardware, with design entry and place-and-route performed in the Libero SoC or legacy Designer software suite. Once antifuses are blown, the configuration is permanent and cannot be erased or updated - so verify your design thoroughly on engineering samples before programming production units. Firmware compatibility of legacy tool versions with modern operating systems should be checked before planning production programming.
A54SX16A vs A54SX32A - which is better for my design?
Choose the A54SX16A-1TQG144 when your design fits within about 16,000 typical gates and you need the lowest cost and a 144-pin TQFP footprint. Choose the A54SX32A family (for example A54SX32A-FTQG144 or FGG144 variants in TQFP-144/QFP footprints) when you need roughly double the logic capacity or more I/O. Both belong to the same SX-A antifuse architecture with similar performance characteristics, but the A54SX32A in a 144-pin package has a different pinout, so switching families requires a pinout review even when package pin counts match.
Is the A54SX16A-1TQG144 still active and RoHS compliant?
Yes. As of 2026-09-03, distributor listings from DigiKey, Mouser, and Microchip USA show the A54SX16A-1TQG144 as an active product status with RoHS3 compliance. The device is a mature SX-A antifuse FPGA originally developed by Actel and continued through Microsemi into Microchip Technology. While active, it is a legacy part with limited stocking and multi-week lead times at some distributors, so lifecycle planning - including qualified drop-in alternates from the same family - is prudent for long-production designs.
Hey Google, what can replace A54SX16A-1TQG144?
The closest replacements are Microchip same-family drop-ins: A54SX16A-1TQG144I (industrial temperature), A54SX16A-1TQG144M, A54SX16A-2TQG144 (faster speed grade), A54SX16A-2TQG144I, and A54SX16A-TQG144A. All share the identical 144-pin TQFP package and pinout, so they solder onto the same PCB footprint. There is no verified cross-brand pin-compatible equivalent - Xilinx, Altera, and Lattice FPGAs of similar density use incompatible SRAM architectures and packages, so a cross-brand move requires a board redesign.

Selection Guide

Choose the A54SX16A-1TQG144 when your design needs roughly 16,000 usable gates of instantly-on, secure, one-time-programmable logic in a 144-pin TQFP at the lowest family cost, and your design closes timing at the -1 speed grade. Choose A54SX16A-1TQG144I or -M when the environment demands industrial or extended temperature grades - same footprint, pin-to-pin. Choose A54SX16A-2TQG144 or -2TQG144I when -1 timing closure is marginal; they cost more but provide timing margin with no PCB change. There is no cross-brand pin-compatible alternative: Xilinx, Altera, and Lattice devices of similar density are SRAM-based with different packages and require configuration memory, so moving off this part is a board redesign, not a substitution. All recommendations assume design verification before one-time programming.

Key Differentiators

  • Instant-on operation with no configuration memory (vs XC4000-class SRAM FPGAs (not pin-compatible))
  • Design security via non-readable antifuse programming (vs SRAM-based FPGA competitors)
  • Speed-grade upgradability on the same footprint (vs A54SX16A-2TQG144)

Design Notes

The A54SX16A-1TQG144 is one-time-programmable: antifuse links are permanently set during programming and cannot be erased or reconfigured. Complete full functional verification and timing closure in the Libero/Designer toolchain on engineering units before programming production devices. Also verify speed grade carefully - a design closed on a -2 part will not necessarily meet timing on the -1 grade. Ordering the wrong speed or temperature suffix (e.g., standard vs I/M grade) is one of the most common sourcing errors on this family, since all variants share one MPN stem.

Supply the core within the verified 2.25V to 5.25V range. Because antifuse FPGAs have no configuration current surge at power-up, inrush is limited to standard CMOS static and dynamic currents - simpler than SRAM FPGA power sequencing. Estimated: use a supply with at least 100 mA headroom above your measured static plus I/O load, and place 0.1 uF ceramic decoupling capacitors at each VCC pin of the TQFP-144 plus one bulk 10 uF per supply domain. Confirm exact ICC figures from the SX-A family datasheet power tables for your utilization.

The TQG144 package is a 20x20 mm 144-lead TQFP, 1.4 mm tall, with 0.5 mm lead pitch. Use a standard TQFP-144 land pattern with approximately 0.5 mm pitch non-solder-mask-defined pads and design pin-1 indexing to match package dot. Reflow soldering is recommended; wave soldering 0.5 mm-pitch QFPs risks bridging. For sourcing flexibility, lay out the footprint to accept any A54SX16A TQG144 speed/temperature grade (I, M, A, -1, -2), which enables drop-in substitution without PCB revision.
