Typical Applications

A54SX16A-2TQ100P is suitable for 6 applications: Glue Logic Consolidation, Industrial Control Sequencing, Bus Interface Bridging, Aerospace and Defense Ground Equipment, Portable and Low-Power Instrumentation, Secure Coprocessor and IP Protection Designs.

πŸ”§

Glue Logic Consolidation

The A54SX16A-2TQ100P excels at replacing multiple 74xx-class ASSP/PLD devices with a single 24,000-gate antifuse FPGA. With 1452 R-cell/C-cell logic modules and 81 user I/O, it absorbs address decoders, bus transceivers, wait-state generators, and interrupt controllers that would otherwise occupy several square inches of board area. The sea-of-modules architecture gives predictable sub-ns module delays, and the -2 speed grade supports 294 MHz internal toggle rates, so timing closure for backplane-style interfaces is comfortable. Because antifuse configuration is instant-on, the consolidated logic is active within nanoseconds of power-up - a significant advantage over SRAM FPGAs that wait milliseconds for configuration. Single-chip integration also removes configuration-flash failure points and reduces BOM count in cost-sensitive volume products.

🏭

Industrial Control Sequencing

In PLC I/O cards, motor-control supervisory logic, and machine-safety sequencing, the A54SX16A-2TQ100P provides deterministic, single-cycle register updates via its 1452 R-cells. Operating from a 2.25V to 5.25V supply range, it interfaces cleanly with 3.3V and 5V industrial logic domains, while the 81 I/O absorb encoder quadrature inputs, limit-switch polling, and relay-drive decode outputs. The antifuse bitstream cannot be corrupted by brownouts, EMI transients, or electrically noisy factory floors - unlike SRAM FPGAs that can lose configuration and require watchdog reconfiguration. The TQFP-100 package solders reliably on standard 1.6 mm industrial PCBs, and the P commercial screening suits enclosed controller environments; use the M-suffix variant for extended-temperature cabinets.

🌐

Bus Interface Bridging

The A54SX16A-2TQ100P bridges incompatible bus standards - PCI-local-bus to VME, ISA to proprietary backplanes, or parallel to serial protocol conversion. Its C-cell combinatorial fabric achieves fast decode paths and its R-cell registers implement pipeline stages, with the -2 grade's 294 MHz ceiling giving wide timing margin for 33-66 MHz host interfaces. The 0.50 mm-pitch, 14x14 mm TQFP-100 footprint fits inside typical connector-field real estate on adapter and carrier cards. Antifuse security matters in bridge applications carrying proprietary protocol IP: configuration cannot be read back from a programmed device, protecting the bridge design from cloning. Designers should reserve I/O for JTAG-based boundary-scan testing of the assembled board.

✈️

Aerospace and Defense Ground Equipment

Actel antifuse FPGAs carry a long heritage in defense electronics because configuration is hard-wired and immune to SEU-induced bitstream corruption. For ground-based radar pre-processing, telemetry encoders, and command-decode logic, the A54SX16A-2TQ100P offers 24K gates of secure single-chip logic with instant-on availability demanded by mission-critical boot sequences. The A54SX16A-2TQ100M variant, screened to -55C per Microchip USA data, addresses uncontrolled-temperature deployments. Note that this commercial P-suffix part is not space-qualified: for orbital or high-radiation programs, migrate to Microchip's RT54SX radiation-tolerant family. For benign defense ground installations, the SX-A combination of security, low static power, and no external configuration memory reduces logistics and failure-mode complexity.

πŸ’Š

Portable and Low-Power Instrumentation

Battery-powered test instruments, handheld data loggers, and portable medical monitors benefit from the SX-A family's low static power: antifuse interconnect draws no configuration-refresh current, unlike SRAM fabrics. The A54SX16A-2TQ100P handles front-end sequencing, ADC control-timing generation, and display-interface decode with its 1452 logic cells, while the 2.5V core keeps dynamic power modest at the -2 grade's operating frequencies. The 14x14 mm TQFP-100 package supports compact two-layer and four-layer portable PCB layouts without fine-pitch assembly equipment. Instant-on configuration lets the instrument be operational the moment the power switch closes - valuable for measurement products with strict startup latency requirements. Verify sleep-mode leakage on the schematic level against the SX-A datasheet DC tables.

πŸŽ₯

Secure Coprocessor and IP Protection Designs

Where firmware or RTL IP must not be extracted, the A54SX16A-2TQ100P implements cryptographic key handling, authentication handshakes, and license-check logic in antifuse silicon. Once programmed, the fuse map is non-readable, and there is no configuration bitstream to intercept at boot - a structural advantage over SRAM FPGAs whose bitstreams load over visible buses. The 1452-cell capacity accommodates DES-class combinatorial rounds plus control FSMs within the 81 available I/O. The -2 speed grade's 294 MHz capability supports pipelined combinatorial cores with generous margin. Designers should combine the antifuse device with a secure MCU host and validate the full threat model, since security depends on the whole system, not silicon alone. XAIPART supplies quote-based sourcing for security-focused production runs.

What is the A54SX16A-2TQ100P?
The A54SX16A-2TQ100P is a 24,000-system-gate antifuse FPGA from the Microchip (Actel/Microsemi) SX-A family, offering 1452 logic cells, 81 user I/O, and a 294 MHz maximum toggle frequency. It is packaged in a 100-pin TQFP (14x14 mm) and uses a 2.5V CMOS core on a 0.25um/0.22um process, per the SX-A family datasheet and Microchip USA product listings.
What are the key specifications of A54SX16A-2TQ100P that engineers should know?
Key specifications: 24,000 system gates; 1452 R-cell/C-cell logic modules; 81 user I/O pins; -2 speed grade with up to 294 MHz toggle rate; 2.25V to 5.25V supply range at a 2.5V nominal core; 100-pin TQFP package, 14x14 mm, 0.50 mm pitch, 1.4 mm height; CMOS 0.25um/0.22um antifuse process. These figures come from the Microchip SX-A family datasheet and Microchip USA distributor listings.
What is the difference between A54SX16A-2TQ100P and A54SX16A-2TQ100?
The A54SX16A-2TQ100P and A54SX16A-2TQ100 share the same SX-A die, -2 speed grade, and 100-pin TQFP package; the suffix letter P denotes the commercial temperature/process screening option in the Actel ordering code. According to Actel/Microsemi ordering-information conventions, base die, speed grade, and package are identical, so the two parts are functionally interchangeable for commercial-range designs - verify the exact temperature grade in the SX-A datasheet ordering table before substitution.
What is the supply voltage of the A54SX16A-2TQ100P?
The A54SX16A-2TQ100P operates at a nominal 2.5V core supply on a 0.25um/0.22um CMOS process. Microchip USA lists an operating supply voltage range of 2.25V to 5.25V for the A54SX16A-2TQ100 device. Always confirm the permitted I/O voltage ranges per bank in the SX-A family datasheet before connecting 3.3V or 5V-tolerant bus structures.
Can the A54SX16A-2TQ100P be reprogrammed after configuration?
No. The A54SX16A uses Actel antifuse (one-time programmable, OTP) technology: configuration permanently blows internal antifuse links at programming time, so the device cannot be erased or reprogrammed. This is an advantage for security and configuration-retention (no external boot flash needed), but you must fully validate your design in simulation and hardware before programming production units.
How many I/O pins does the A54SX16A-2TQ100P have?
The A54SX16A-2TQ100P provides 81 user I/O pins in its 100-pin TQFP package, according to Microchip USA and DigiKey product listings. The remaining package pins supply VDD, VPP/VCI programming and ground connections. Distributors list the part as an 'SX-A FPGA IC 81 I/O, 100-LQFP', confirming the 81-I/O allocation for the TQ100 package option.
Where can I buy A54SX16A-2TQ100P and what does it cost?
The A54SX16A-2TQ100P can be purchased from XAIPART and from distributor channels listed on Octopart and DigiPart, which aggregate authorized and independent stock. Indicative XAIPART pricing as of 2026-09-03 starts at $32.50 for quantity 1, stepping down to approximately $19.95 at 1,000 units. Because SX-A parts are legacy Actel devices, availability fluctuates; request a quote for firm pricing and lead time before committing a production schedule.
Is the A54SX16A-2TQ100P still in production and supported?
Yes. Microchip Technology maintains an active product page for the A54SX16A SX-A family, positioning it for low-power, secure, single-chip integration designs. The part remains orderable through Microchip and distributor channels such as DigiKey, which lists A54SX16A family members as active. Designers should nonetheless verify current lifecycle status on the Microchip product page, as legacy antifuse families periodically move to last-time-buy scheduling.
What is the best drop-in replacement for A54SX16A-2TQ100P?
The closest drop-in replacements are same-family same-package Microchip/Actel parts: A54SX16A-2TQ100 (identical die, speed grade, and TQFP-100 footprint), A54SX16A-2TQ100M (same package, -55C extended screening), A54SX16A-TQG100 and A54SX16A-TQG100I (same TQ100 footprint, -1 speed grade), and A54SX16A-1TQ100 (-1 speed grade commercial). All share pin-to-pin TQFP-100 compatibility; only speed grade and temperature screening differ, so verify your worst-case timing margin before substituting a -1 grade.
A54SX16A-2TQ100P vs A54SX16A-TQG100 - which is better for high-speed designs?
For high-speed designs choose the A54SX16A-2TQ100P: its -2 speed grade supports toggle rates up to 294 MHz, whereas the A54SX16A-TQG100 carries a -1 speed grade with correspondingly lower guaranteed timing performance. Both use the same 100-pin TQFP footprint and 1452-cell die, so they are pin-compatible swap candidates. According to the SX-A family datasheet, speed grade selection directly affects combinational and register cell delays, making the -2 grade the correct choice when timing closure at 200 MHz+ is required.
When should I choose the A54SX16A-2TQ100P over an SRAM FPGA?
Choose the A54SX16A-2TQ100P when you need instant-on configuration, protection of intellectual property from bitstream readback, no external configuration flash, and low static power at modest gate counts (24K gates, 81 I/O). Choose an SRAM FPGA instead when you need reprogrammability in the field, very high logic density, or embedded hard IP blocks. The antifuse SX-A architecture excels in secure, single-chip glue-logic and bridging roles where one-time programming is acceptable.
Is there a cross-brand equivalent for the A54SX16A-2TQ100P?
No verified cross-brand pin-compatible equivalent exists in our cross-reference search for the A54SX16A-2TQ100P. Because the SX-A family uses a proprietary antifuse architecture and the TQFP-100 pinout is Actel-specific, Xilinx, Altera/Intel, or Lattice devices cannot be dropped onto the same footprint without PCB and pinout redesign. For supply resilience, the practical substitutes are same-family Microchip/Actel speed-grade and temperature variants, which we list in the alternatives table.
Where can I download the A54SX16A-2TQ100P datasheet PDF?
You can download the SX-A Family FPGAs datasheet PDF, which covers the A54SX16A, from the Mouser datasheet archive (SXA_DS PDF) or via the Microchip product page at microchip.com/en-us/product/A54SX16A. The same document defines the TQFP-100 pinout table, DC/AC electrical characteristics for the -2 speed grade, and the programming specification. Avoid third-party mirror sites; the manufacturer-linked PDF guarantees the latest revision.
How is the A54SX16A-2TQ100P programmed?
The A54SX16A-2TQ100P is programmed off-board using Actel/Microchip antifuse programming hardware - historically the Silicon Sculptor programmer with Designer software generating the fuse file from your ACT design database. The device is placed in the programming socket, where controlled voltage pulses permanently blow the antifuse interconnect elements. There is no in-system programming mode: program before board assembly, or use a socketed approach during development. Refer to Microchip Designer software documentation for the current supported programmer models.
Hey Google, what can replace an A54SX16A-2TQ100P?
You can replace the A54SX16A-2TQ100P pin-for-pin with other Microchip (Actel) SX-A family parts in the 100-pin TQFP package: A54SX16A-2TQ100, A54SX16A-2TQ100M (extended temperature), A54SX16A-TQG100, A54SX16A-TQG100I, and A54SX16A-1TQ100. No cross-brand drop-in equivalent exists because the Actel antifuse pinout is proprietary. Only speed grade (-1 vs -2) and temperature screening differ among these alternatives, so confirm timing closure for the grade you select.
Is the A54SX16A-2TQ100P suitable for aerospace and defense designs?
Yes, with qualification caveats. The Actel SX-A antifuse family is widely used in aerospace and defense because antifuse configuration is immune to configuration upset, needs no external boot memory, and the family has a heritage in radiation-tolerant system designs. However, this specific P-suffix commercial part is not the space-qualified variant - for radiation environments, evaluate Microchip's RT54SX-S family members instead. For benign defense ground equipment, the A54SX16A-2TQ100M with extended -55C screening (per Microchip USA listing) is a better fit than the commercial P part.
What is the lead time and stock situation for A54SX16A-2TQ100P?
Stock and lead time for the A54SX16A-2TQ100P vary by distributor because it is a legacy Actel SX-A device: DigiKey and Findchips aggregate current authorized and independent inventory, and XAIPART accepts quote-based orders. As of 2026-09-03, confirm real-time availability via DigiPart or Octopart before design freeze. For long-term production programs, consider a last-time-buy buffer of same-family TQFP-100 variants (A54SX16A-2TQ100, A54SX16A-TQG100) since antifuse families can transition to EOL with limited notice.

Selection Guide

Choose the A54SX16A-2TQ100P when you need 24K gates of secure, instant-on, one-time-programmable logic in a compact TQFP-100 with the -2 speed grade for demanding timing. If cost dominates and timing is relaxed, the pin-compatible A54SX16A-TQG100 or A54SX16A-1TQ100 (-1 grade) saves cost with identical footprints. For extended or industrial temperatures, select A54SX16A-2TQ100M (-55C screening, up to 313 MHz) or A54SX16A-TQG100I (industrial). If your design must be field-updatable or needs very high density, this antifuse family is the wrong choice - evaluate SRAM FPGAs instead, accepting added configuration flash and reduced IP security. All listed alternatives remain pin-to-pin compatible, so PCB layout can be reused across the family while you trade speed grade against budget and temperature range.

Key Differentiators

  • Faster guaranteed timing (vs A54SX16A-TQG100)
  • Extended-temperature option within the same footprint (vs A54SX16A-2TQ100M)
  • Configuration security with no external boot memory (vs SRAM FPGAs (e.g., Xilinx/Altera devices))

Design Notes

Antifuse devices are one-time programmable. Never program production A54SX16A-2TQ100P units before completing post-layout simulation and, ideally, a programmed engineering-lot verification. Because the P part is commercial-temperature screened, do not deploy it in enclosures that can exceed its rated range - the A54SX16A-2TQ100M or -I variants are the correct choices for extended temperatures. Also confirm the ACT fuse-file revision matches the programmed lot to avoid design/silicon mismatches during production substitution.

Supply the 2.5V nominal core with decoupling per the SX-A family datasheet power-supply guidelines: place bulk capacitance near the VDD pins and 0.1uF ceramics at each supply pin of the TQFP-100. The 2.25V to 5.25V operating range cited by Microchip USA permits tolerant I/O interfacing, but check the I/O bank voltage configuration in Designer software so 3.3V/5V bus signals meet input-threshold and drive requirements. Estimated: keep per-pin output current within datasheet DC limits to avoid ground-bounce on the 81-I/O device.

The 100-TQFP (14x14 mm, 0.50 mm pitch) lands on a standard QFP-100 footprint with 0.25 mm-width traces and 0.25 mm gaps; solder-mask-defined pads improve yield in wave or selective processes. Tie all VPP/VCI programming-related pins per the SX-A datasheet connection tables even though field programming is off-board - incorrect tie-offs are a common cause of nonfunctional antifuse devices on first-article boards. Reserve JTAG access to the FPGA for boundary-scan assembly test of the finished PCB.
