A54SX16A-2TQG100I 概要
An antifuse FPGA is a type of field-programmable gate array whose interconnects are permanently programmed at power-up by blowing on-chip antifuse links. Unlike SRAM-based FPGAs, antifuse devices are non-volatile, require no configuration PROM, offer inherent resistance to bit-stream reverse engineering, and draw no configuration power, making them a secure, low-power branch of the programmable logic taxonomy that sits alongside flash-based and SRAM-based FPGA architectures.
Key features of the A54SX16A-2TQG100I include 1,452 configurable logic blocks (CLBs), a wide 2.25V to 5.25V supply voltage range supporting mixed-voltage systems, and the speed-grade -2 performance tier, which supports system toggle frequencies up to 294 MHz. The device is fabricated in CMOS, and the antifuse fabric provides deterministic interconnect delays that simplify timing closure in high-reliability designs.
Architecturally, the SX-A family uses a sea-of-modules structure composed of logic modules and register cells surrounded by a horizontal and vertical routing channel mesh. The high routing capacity yields high routability and fast pin-to-pin delays. Because configuration is stored in antifuse elements rather than SRAM, the programmed design survives power cycling with zero startup latency and cannot be read back, an important security property for defense and industrial designs.
Typical applications include industrial control and automation, glue-logic consolidation, bus interface bridging, secure military and avionics subsystems, and communication equipment where single-chip integration of multiple discrete functions lowers system cost. With 81 I/Os and 24K gates, this density point fits medium-complexity control and interface logic.
When designing with this device, plan for one-time programmability: unlike SRAM FPGAs, the antifuse fabric cannot be reprogrammed, so exhaustively verify the design in simulation and on a reprogrammable prototyping path before committing production parts. The 2.25V to 5.25V supply window simplifies legacy 3.3V and 5V board integration.

主な用途
A54SX16A-2TQG100I の用途: 6 件s: Industrial Control and Automation, Secure Defense and Avionics Subsystems, Glue Logic Consolidation, Communications Equipment Interface Bridging, Power Supply and Housekeeping Sequencing, Test and Measurement Instrumentation.
Industrial Control and Automation
Factory automation controllers benefit from the A54SX16A-2TQG100I's industrial temperature rating of -40C to +85C and its wide 2.25V to 5.25V supply window, which interfaces cleanly with legacy 5V and modern 3.3V PLC I/O rails without level-shifting. The 24K system gates and 81 user I/Os are sufficient to consolidate discrete counters, sequencers, and bus-interface glue logic into a single antifuse chip, cutting BOM cost and board area. Because the antifuse configuration is non-volatile, the controller starts instantly at power-up with no configuration device and no boot delay, an operational advantage on production lines where every cycle counts.
おすすめ
Secure Defense and Avionics Subsystems
The A54SX16A-2TQG100I fits defense and avionics platforms that demand design security: the antifuse bitstream cannot be read back, and the M-suffix siblings (such as A54SX16A-1TQG100M) serve military-range applications within the same footprint. The -2 speed grade supports toggle rates up to 294 MHz for interface and telemetry logic, while deterministic antifuse interconnect delays simplify worst-case timing analysis required in safety-reviewed designs. Non-volatile configuration removes external configuration PROMs, reducing both the part count and a common attack and failure surface in radiation- and tamper-conscious environments.
おすすめ
Glue Logic Consolidation
Board designers frequently use the A54SX16A-2TQG100I to replace dozens of 74-series logic devices, PALs, and GALs. With 24K system gates, 1,452 CLBs, and 81 I/Os, a single chip absorbs address decoders, wait-state generators, interrupt arbiters, and bus transceivers, shrinking PCB area and eliminating device-to-device timing skew. The 294 MHz toggle capability covers even fast bus decode paths, and the 100-TQFP (14x14 mm) footprint with 1.4 mm profile suits dense 2-4 layer industrial boards. Instant-on antifuse configuration means the consolidated logic is active within nanoseconds of power application, matching the behavior of the discrete devices it replaces.
おすすめ
Communications Equipment Interface Bridging
Line cards and backplane adapters use the A54SX16A-2TQG100I to bridge protocol domains, for example converting between a parallel local bus and serial framing interfaces. The -2 speed grade sustains internal clock rates up to 294 MHz, adequate for T1/E1-class and fast parallel data paths, while 81 I/Os provide enough pins for dual-bus bridging with parity. The wide 2.25V to 5.25V supply eases integration with mixed-voltage backplanes common in telecom shelves. Because configuration is fixed in antifuse, the bridge logic is present immediately at hot-swap power application, avoiding the enumeration delay of SRAM FPGAs.
おすすめ
Power Supply and Housekeeping Sequencing
The instant-on nature of antifuse configuration makes the A54SX16A-2TQG100I attractive for power-supply supervisory and sequencing logic in multi-rail systems. Unlike SRAM FPGAs that are blank for milliseconds during configuration, this device executes sequencing, brown-out, and enable-chain logic from the first instant of power, using its 2.25V supply floor. The 24K-gate capacity implements voltage monitors, PWM gates, and fault latches with spare room for revision changes that would otherwise force a respin of a discrete-logic board. Its -40C to +85C range covers outdoor telecom rectifiers and industrial power shelves.
おすすめ
Test and Measurement Instrumentation
Bench instruments and automated test fixtures use the A54SX16A-2TQG100I for timing generation, pattern capture, and interface control. Deterministic antifuse routing delays allow repeatable edge placement across production units, supporting measurement repeatability, while the 294 MHz toggle ceiling covers fast clock and strobe generation. The 81 I/Os connect counter chains and pattern registers to a host bus, and industrial temperature rating permits use in unconditioned test-floor environments. Because the design is permanently programmed, instrument firmware-as-logic cannot drift between power cycles, improving long-term calibration stability.

設計ノート
The A54SX16A-2TQG100I is one-time programmable. Unlike an SRAM FPGA, an antifuse part cannot be reprogrammed after a logic change, so a functional bug means scrapping the device. Budget for the full verification flow: RTL simulation, gate-level timing simulation with the SX-A place-and-route delays, and hardware prototyping before committing production silicon. Purchase one or two extra devices per revision cycle as programming-yield spares, since antifuse programming yield is not 100 percent.
The 2.25V to 5.25V supply range supports 2.5V, 3.3V, and 5V systems, but all I/O thresholds and output drive scale with the chosen rail. Decouple the VCC pins with at least 0.1uF ceramic capacitors placed within 5 mm of each supply pin plus bulk 10uF capacitance near the package. Avoid sequencing violations between VCC and input signals driven by external devices; external logic should not drive SX-A inputs before the supply rail is established.
At -2 speed grade toggle rates approaching 294 MHz, treat outputs faster than roughly 50 MHz as transmission-line loads: add 22-50 ohm series termination resistors near the TQFP pins for point-to-point traces longer than about 5 cm. Match trace lengths for bus groups to minimize skew. The 14x14 mm TQFP has inductive leads (~1-2 nH per pin, typical estimate), so ground return paths must be direct; use a solid ground plane on layer 2 directly under the device.
Estimated: at 24K-gate typical utilization with moderate toggle activity, the SX-A family's low static CMOS current keeps dissipation typically below 1 W at 3.3V. The 100-TQFP theta_JA of approximately 60-90 C/W (estimate; consult the Microchip SX-A datasheet thermal table for the exact value) keeps junction rise under 60 C in still air at 1 W. For -2 grade designs clocked continuously at high frequency, verify dynamic power with Microchip's power calculator and consider airflow if ambient exceeds +70C.
