A54SX16A-TQG100 개요
A field programmable gate array (FPGA) is a semiconductor device containing configurable logic blocks and programmable interconnects that designers configure after manufacturing. The SX-A family belongs to the antifuse FPGA category within the broader programmable logic hierarchy (FPGA -> programmable logic device -> digital IC -> semiconductor). Unlike SRAM-based FPGAs, antifuse devices are one-time programmable, which permanently locks the configuration and makes the design immune to readback, giving inherent security and radiation-tolerant behavior advantages for aerospace and defense systems.
Key features include 16,000 typical usable gates (24,000 system gates), a sea-of-modules architecture that delivers deterministic interconnect delays, 0.25 um/0.22 um CMOS process technology, and a 2.5 V core supply. The 924 configurable logic cells with dedicated flip-flops support pipelined designs at up to 227 MHz, dramatically outperforming typical SRAM FPGAs of the same era for glue logic and high-speed state machines.
Architecturally, the SX-A uses Actel's sea-of-modules structure with C-cells (combinational) and R-cells (register) tiled across the die, connected through a segmented routing fabric. Because antifuse interconnects have very low on-resistance and capacitance, timing is fast and predictable, and total power consumption is substantially lower than equivalent SRAM FPGA implementations.
Typical applications include aerospace and defense logic replacement, industrial control, communication bridging, medical equipment glue logic, and obsolescence-driven ASIC integration where a single-chip, non-volatile, secure FPGA is required.
When designing with this device, note it is one-time programmable: functional verification in simulation (Libero IDE/Designer) must be completed before programming, and design lock-up files must be retained for future respins. Observe the 2.25 V to 5.25 V I/O supply constraints on the specified pins.

Aerospace and Defense Logic Integration
The A54SX16A-TQG100 fits aerospace and defense payload and avionics logic because its antifuse configuration is inherently non-volatile, cannot be read back, and is immune to configuration upset from single-event effects compared with SRAM FPGAs. The 24,000 system gates and 2,012 flip-flops integrate multiple glue-logic, bus-interface, and state-machine functions that previously required several discrete devices, while the 227 MHz rating supports high-speed data path pipelines. Because no configuration PROM is needed at power-up, the design boots instantly and eliminates an entire failure mode. Designers compile once, verify exhaustively in simulation, then program with the Silicon Sculptor flow; the permanently programmed interconnect also improves long-term reliability in vibration and thermal-cycling environments typical of defense platforms.

Industrial Control and Automation
In industrial control, the A54SX16A-TQG100 replaces multi-chip TTL/CPLD glue logic with a single 2.5 V-core, low-static-power antifuse FPGA. Its 81 user I/O handle sensor polling, motor-controller handshaking, and backplane interfacing, while the deterministic antifuse routing guarantees repeatable timing across production units - valuable when PLC I/O modules must meet fixed response windows. The one-time-programmable configuration prevents field tampering of control firmware, and the commercial 0C to +70C grade suits enclosure-based controllers. With 16,000 typical gates, an entire address decoder, interrupt controller, and PWM generator fit on one die, cutting BOM count and assembly cost. Layout effort is modest: the 100-pin TQFP with 0.5 mm pitch routes on two signal layers with standard ground pours.
추천
Medical Equipment Logic
Medical diagnostic equipment benefits from the A54SX16A-TQG100's combination of deterministic timing and secure non-volatile configuration. Patient-interface modules, ultrasound front-end sequencing, and instrument backplane bridges use the 81 user I/O and 227 MHz pipeline capability to meet fixed-latency requirements across calibration and production units - something SRAM FPGAs cannot always guarantee due to routing variability. The antifuse fabric draws near-zero static power, reducing thermal load inside sealed instrument enclosures and improving patient-contact surface temperature compliance. Since the configuration cannot be read back or altered, it supports data-integrity expectations of regulated medical device development. Designs integrate sample-sequencing state machines, filter control, and communication glue logic within the 24K system-gate budget on the compact 100-pin TQFP footprint.
추천
Communications and Bridging
The SX-A family was explicitly positioned by Actel/Microchip for performance-intensive communication designs, and the A54SX16A-TQG100 delivers bridge, multiplexer, and framing logic at up to 227 MHz with deterministic antifuse delays. Typical roles include protocol conversion between legacy backplanes and modern interfaces, serial-to-parallel deskewing, and data-path grooming in line cards and network appliances. The sea-of-modules architecture keeps interconnect capacitance low, so high toggle rates consume less dynamic power than the equivalent SRAM FPGA implementation, easing card-level thermal budgets. The 100-pin TQFP suits short-trace, point-to-point topologies at moderate speeds; follow datasheet I/O standards and add series termination for the fastest banks. One-time programming also prevents unauthorized alteration of deployed network configuration logic.
추천
ASIC Prototyping and Obsolescence Integration
Engineers frequently use the A54SX16A-TQG100 to consolidate aging ASIC, gate-array, or multiple-CPLD designs that face end-of-life, achieving single-chip integration at 16,000 typical gates. The antifuse device becomes a permanent, mask-like replacement: once programmed, it behaves like a fixed-logic ASIC, which simplifies qualification for legacy sockets because there is no possibility of configuration drift or bit-flip in the fabric. Migration typically requires re-entering the netlist in Libero/Designer, retiming for the SX-A architecture, and validating against the original test vectors. Compared with a full ASIC respin, an antifuse FPGA migration costs far less in NRE and reaches production in weeks, making it the standard obsolescence-management approach for 24K-gate-class legacy designs in long-lifecycle equipment.
추천
Secure Embedded Systems
The A54SX16A-TQG100 serves secure embedded platforms where firmware extraction must be impossible: antifuse configuration bits cannot be read back through any documented interface, and the programmed netlist is physically embedded in the die. Security-critical functions such as key-handling state machines, tamper-response logic, and access-control sequencing fit within the 24K system gates with room for the peripheral interface logic. Unlike SRAM FPGAs that load bitstreams from external flash at every power-up - exposing the design to interception - this device stores its entire configuration internally and boots instantly with no external configuration memory to attack or fail. Combined with low static power and the compact 100-pin TQFP, it is a practical security anchor for industrial and infrastructure controllers.

설계 노트
The A54SX16A-TQG100 uses a 2.5 V core with device supply pins per the SX-A datasheet power table for the 100-pin TQFP. Because antifuse fabric draws negligible static current, dynamic power dominates and scales with clock frequency and toggle rate; at 227 MHz designs, provide a low-impedance 2.5 V plane and decouple every supply pin pair with 100 nF ceramics plus 10 uF bulk. Estimate power with Actel/Microchip power calculator before finalizing the regulator - do not size the rail by gate count alone.
The 100-pin TQFP has 0.5 mm lead pitch. Use 0.25 mm solder-mask-defined pads per the datasheet land pattern, and fan out with 5-mil trace/5-mil space to escape all 25 pins per side on two signal layers. Tie exposed corner marks to pin 1 per the package drawing. Do not route fast clocks (>50 MHz) on the innermost pins if trace length matching is required - reserve perimeter pins for the highest-speed I/O to minimize stub length.
This is a one-time-programmable antifuse FPGA: a mis-verified design cannot be reprogrammed, so full gate-level simulation and static timing sign-off in Libero/Designer are mandatory before programming production devices. Retain the lock-up file and design archive for the product lifetime. Also verify speed-grade suffix at ordering - a -1 part placed by a standard-grade BOM will pass visual inspection but not timing on faster designs.
Antifuse interconnect gives deterministic on-chip delays, but board-level I/O still needs termination. For edges faster than approximately 2 ns, add 22-50 ohm series resistors at the FPGA driver or parallel termination at the receiver, per the SX-A datasheet I/O guidelines. Keep stub lengths under 15 mm for the fastest banks and reference high-speed signals to a continuous ground plane; the 100-pin TQFP's lead inductance (~10 nH estimated) limits achievable edge rates at heavily loaded outputs.
