A54SX16A-2TQ100P Présentation
An antifuse FPGA is a field-programmable gate array whose interconnect is permanently programmed by blowing microscopic antifuse links at power-up configuration. Unlike SRAM-based FPGAs from Xilinx or Altera, antifuse devices such as the SX-A family need no external configuration memory, offer inherent resistance to configuration corruption, and exhibit lower static power - placing them in the broader hierarchy of programmable logic within the semiconductor and power-management system ecosystem.
Key features include the sea-of-modules architecture built from R-cells (register cells) and C-cells (combinatorial cells), a 2.5V CMOS core fabricated on a 0.25um/0.22um process, operation from a nominal 2.5V supply with the documented 2.25V to 5.25V I/O supply range cited by Microchip USA, and single-chip integration that removes external boot flash. The 81 available user I/O deliver broad pinout flexibility in the compact 14x14 mm TQFP-100 body.
Architecturally, the SX-A device floor is covered with a grid of logic modules virtually free of routing overhead, giving predictable timing. Cluster and direct interconnect routing minimizes delay, and the -2 speed grade supports clock rates approaching 294 MHz as reported by distributor datasheet listings, with the M automotive-style variant listed up to 313 MHz.
Typical applications include glue-logic consolidation, bus interface bridging, industrial control sequencing, and aerospace/military designs that exploit the antifuse family's radiation-tolerant heritage and security advantages.
Design consideration: antifuse programming is one-time and irreversible - fully verify the design in simulation before programming production devices, and budget the required ACT/Silicon Sculptor programmer access.

Applications typiques
A54SX16A-2TQ100P convient pour 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.
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.
Recommandé
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.
Recommandé
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.
Recommandé
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.
Recommandé
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.

Notes de conception
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.
