A54SX16A-TQG100A 概要
An FPGA (Field Programmable Gate Array) is a semiconductor device containing configurable logic blocks (CLBs) and programmable interconnects that the designer wires together after manufacturing, allowing custom digital logic without fabricating an ASIC. Within the programmable-logic hierarchy, the A54SX16A belongs to the one-time-programmable antifuse FPGA category under the broader classes of programmable logic devices and application-specific integrated circuit alternatives. Antifuse technology stores its configuration physically, offering inherent resistance to radiation-induced configuration upsets and cloning.
Key features of the A54SX16A-TQG100A include 24,000 equivalent system gates with approximately 16,000 typical gates available for design implementation, 1,452 configurable logic blocks organized in the SX-A sea-of-modules architecture, and a wide supply voltage range of 2.25V to 5.25V that simplifies integration into mixed-voltage systems. The device is fabricated on a 0.25 um CMOS process and supports an operating temperature range of -40C to +125C (TA), suitable for harsh-environment and automotive-adjacent applications.
Technically, the SX-A family delivers high performance through its Sea-of-Modules architecture with low routing delay, achieving a maximum toggle rate of 227 MHz while keeping static power consumption low compared to SRAM-based FPGAs. Because configuration is stored in antifuse elements, the device powers up instantly with no external configuration PROM, reducing board cost, boot time, and configuration-glitch security risks.
Typical applications include industrial control and automation logic, glue logic and bus-interface integration, communication and networking control functions, and military or aerospace systems where single-chip integration, low power, and configuration security are valued. Replacing multiple discrete MSI/SSI devices with one A54SX16A reduces board area, assembly cost, and inventory.
A key design consideration is that antifuse FPGAs are one-time programmable: programming errors cannot be corrected in-circuit, so thorough simulation and the vendor programming service flow must be completed before commit. Pinout flexibility at design entry should also be fixed before programming.

主な用途
A54SX16A-TQG100A の用途: 6 件s: Industrial Control and Automation, Glue Logic and Bus Interface Integration, Aerospace and Defense Systems, Communications and Networking Equipment, Automotive Electronic Control Units, Secure and Tamper-Resistant Designs.
Industrial Control and Automation
The A54SX16A-TQG100A consolidates PLC I/O sequencing, encoder decoding, and interlock logic into a single 24K-gate antifuse fabric with 81 user I/O. Its wide 2.25V to 5.25V supply range interfaces directly with legacy 5V and 3.3V industrial backplanes without level-shifters, and the -40C to +125C (TA) rating covers sealed cabinet environments. Because configuration is held in antifuse elements, the logic is active within microseconds of power application - no bitstream loading delay - so safety interlocks and motor-enable chains can be asserted immediately at power-up. Once programmed, the design cannot be altered by firmware faults or electrical transients, increasing system integrity in unattended factory-floor installations.
おすすめ
Glue Logic and Bus Interface Integration
A core value proposition of the SX-A family is replacing dozens of MSI/SSI devices - address decoders, bus transceivers, wait-state generators, and interrupt controllers - with one A54SX16A-TQG100A, saving board area and assembly cost. The 227 MHz toggle capability comfortably handles microprocessor bus timing on legacy 16/32-bit buses, and 81 I/O pins support wide parallel data paths in the 14x14 mm TQFP. Its one-time-programmable antifuse configuration adds no configuration PROM to the BOM and eliminates boot-time configuration glitches, which matters for CPU reset and chip-select logic that must be valid from the first clock edge in embedded controllers and bridge applications.
おすすめ
Aerospace and Defense Systems
Antifuse FPGAs are a mainstay in aerospace payloads and avionics because the A54SX16A-TQG100A's configuration is a physical connection that cannot be upset by single-event effects, unlike SRAM configuration cells that require scrubbing. The part operates from -40C to +125C, draws low static power from a 2.25V to 5.25V rail - valuable in battery- and constrained-power platforms - and provides no readback path for configuration, protecting proprietary or mission-critical logic. Typical uses include telemetry formatting, spacecraft mode-control logic, and radar timing chains, where the 227 MHz performance and deterministic instant-on behavior are matched to flight-qualified design flows.
おすすめ
Communications and Networking Equipment
In telecom line cards and networking backplanes, the A54SX16A-TQG100A implements framing, clock-domain crossing, and backplane interface logic with 924 logic modules and up to 227 MHz internal performance. The 81 user I/O in the compact 14x14 mm TQFP suits dense card layouts, and 5V-tolerant operation within the 2.25V to 5.25V supply window eases integration with legacy telecom signaling. Because the antifuse configuration is fixed at manufacture, deployed units behave identically for their service life - an advantage in carrier equipment where firmware-triggered configuration corruption must be designed out. Deterministic routing delays also simplify timing closure on protocol-critical paths.
おすすめ
Automotive Electronic Control Units
The -A suffix of the A54SX16A-TQG100A designates an automotive/extended temperature grade rated -40C to +125C (TA), targeting under-hood and body-control logic such as door modules, HVAC sequencing, and powertrain auxiliary control. The antifuse fabric starts instantly at key-on with no configuration load time, so safety-relevant outputs are valid within microseconds - faster than MCU firmware boot. With 24,000 gates and 81 I/O, a single device typically replaces an MCU-external logic cluster, cutting component count and improving fault containment. Designers should confirm formal AEC-Q100 qualification scope with Microchip for the specific program before release.
おすすめ
Secure and Tamper-Resistant Designs
The A54SX16A-TQG100A provides hardware-level configuration security: the antifuse programming data cannot be read back through any device interface, so competing bitstream-extraction attacks that work against SRAM FPGAs are not applicable. This makes the device well suited for key storage logic, license enforcement, cryptographic wrapper control, and anti-counterfeiting circuitry in networking and payment terminals. The 24K-gate fabric can host control logic around external crypto cores, and instant-on antifuse configuration ensures the security perimeter is active before the host processor leaves reset - eliminating the unsecured window inherent to SRAM FPGA boot sequences.

設計ノート
The A54SX16A-TQG100A accepts 2.25V to 5.25V on its core supply, but internal timing is specified at nominal conditions - consult the SX-A datasheet DC characteristics for valid VCC/VCCA combinations per speed grade. Static current in antifuse devices is very low compared to SRAM FPGAs, so standby power is rarely the limiting factor; dynamic power scales with clock frequency and switching activity, so gate the clock tree for idle blocks. Decouple VCC and VCCA pins with 0.1 uF ceramics placed within 2 mm of each supply pin on the TQFP footprint.
Antifuse FPGAs are one-time programmable: there is no rework path after the programming current blows the fuse links. Complete full functional simulation in Libero/Microchip design tools, verify I/O assignments against the 100-TQFP pinout table, and program a pilot unit before committing a production batch. Reserve a spare dedicated pin budget for future debug access because pins cannot be reassigned post-commit. Also confirm the temperature suffix (-A vs -I) matches your worst-case ambient - the -I grade tops out at +85C.
The 100-TQFP (14x14 mm) has 0.5 mm pin pitch; design land patterns to the Microchip SX-A datasheet package drawing and use solder-mask-defined pads per IPC guidance verified against your fabricator's capabilities. Provide at minimum a 2x2 via fan-out under the device for thermal relief and low-inductance ground return. Underside thermal resistance depends on copper area per the SX-A datasheet thermal characteristics section - at -40C to +125C operation, estimate junction temperature with your actual dynamic power rather than worst-case gate count.
Estimated: with 24,000 gates and low antifuse static current, typical dissipation in glue-logic applications is well under 0.5 W, which a standard 4-layer PCB with ground plane dissipates without heatsinking. For designs clocking heavily toward the 227 MHz limit, compute dynamic power from the Microchip power calculator output and multiply by the TQFP-100 theta_JA from the SX-A datasheet thermal table to verify junction temperature stays below the +125C ambient-rated envelope.
