A54SX16A-1TQG100I 概要
An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a fabric of configurable logic blocks and programmable interconnects that designers configure to implement custom digital circuits. Within the programmable logic hierarchy, the SX-A sits in the one-time-programmable (OTP) antifuse FPGA category, positioned below flash-based and SRAM-based FPGAs but offering superior security and instant-on behavior. The sea-of-modules architecture of the SX family simplifies design migration and reduces power consumption relative to SRAM FPGAs.
Key differentiating features include the antifuse fabric, which is non-volatile, requires no configuration PROM, and resists bit-stream extraction, making designs exceptionally hard to clone. The -1 speed grade supports clock rates up to 263 MHz toggle, and the 2.5V core delivers low static power compared with older 3.3V-generation FPGAs. The 100-lead TQFP (1.4 mm height) provides a cost-effective, hand-assembly-friendly surface-mount footprint.
The SX-A architecture organizes logic into C-cells and R-cells with dedicated fast carry chains and a segmented routing matrix, enabling efficient datapath, state-machine, and glue-logic implementations. Because configuration is stored in antifuses, the device powers up instantly with no boot latency, and there is no external configuration flash to corrupt.
Typical applications include industrial automation control, aerospace and defense subsystems, bridge/protocol conversion, bus interface bridging, and replacing multiple ASIC/MSI glue-logic chips in a low-cost single-chip solution.
A key design consideration: antifuse FPGAs are one-time programmable, so prototype thoroughly in simulation; choose speed grade and package with future upgrades in mind since the same TQG100 footprint accommodates other SX-A family members.

主な用途
A54SX16A-1TQG100I の用途: 6 件s: Industrial Automation Control, Aerospace and Defense Subsystems, Protocol and Bus Bridging, Glue Logic Integration and BOM Reduction, Test and Measurement Equipment, Secure Embedded Systems.
Industrial Automation Control
The A54SX16A-1TQG100I fits industrial control and automation boards where deterministic, instant-on logic is required near motors, sensors, and PLC backplanes. Its 24,000 system gates and 1452 CLBs absorb glue logic, state machines, and interface bridging that would otherwise occupy several MSI/PLD devices, cutting BOM cost and board area. The industrial -40C to +85C rating and 2.5V core (low static power) suit unattended factory-floor cabinets. Because the antifuse fabric needs no configuration flash, the FPGA is active the instant power is applied, eliminating boot delays in safety interlocks. Designers implement counters, PWM generators, and parallel bus interfaces across the 81 user I/Os at toggles up to 263 MHz.
おすすめ
Aerospace and Defense Subsystems
The SX-A antifuse architecture makes the A54SX16A-1TQG100I attractive for defense electronics such as avionics interface adapters, telemetry encoders, and secure logic where configuration tamper-resistance matters. Antifuse interconnects are one-time programmed and cannot be read back, providing inherent IP protection unavailable in SRAM FPGAs that store bitstreams in external flash. Instant-on behavior removes configuration-latency concerns in power-cycled payloads, and the absence of a configuration device removes a common failure point. The M-grade sibling (A54SX16A-1TQG100M) extends temperature coverage for harsher environments in the same footprint, enabling a single PCB to serve multiple environmental classes.
おすすめ
Protocol and Bus Bridging
The A54SX16A-1TQG100I is well suited to bridging legacy parallel buses, backplane interfaces, and asynchronous protocol converters. With 81 user I/Os and dedicated fast routing in the sea-of-modules fabric, designers map wide parallel data buses and generate handshaking state machines operating at toggle rates up to 263 MHz on the -1 speed grade. Instant-on antifuse configuration means the bridge is functional before host processors complete boot, which matters in systems where the FPGA must pass through early-bus traffic. Because the design is fixed after programming, bridge behavior is fully deterministic across every unit shipped, simplifying qualification for industrial and defense programs.
おすすめ
Glue Logic Integration and BOM Reduction
A primary SX-A value proposition stated by Microchip is system-wide savings from integrating multiple functions into a low-cost single-chip solution. The A54SX16A-1TQG100I replaces clusters of 74xx MSI devices, GALs, and CPLDs with one 100-pin TQFP, shrinking board area, cutting assembly cost, and eliminating multi-vendor obsolescence risk. The 24,000 system gates comfortably hold address decoders, wait-state generators, interrupt controllers, and bus transceiver control. Compared with SRAM CPLDs, the antifuse fabric draws near-zero static current, valuable in always-on industrial equipment. The TQFP package supports straightforward rework and inspection, lowering total manufacturing cost for mid-volume boards.
おすすめ
Test and Measurement Equipment
Bench and rack instrumentation benefits from the A54SX16A-1TQG100I as timing, trigger, and scanner control logic. The -1 speed grade supports toggling to 263 MHz, sufficient for trigger decision paths and event counters, while the 81 user I/Os interface front-panel switches, relays, and multiple measurement channels. One-time-programmable configuration guarantees that a calibration profile baked into the logic cannot drift or be corrupted by a failed configuration device, an advantage over SRAM FPGAs in fielded instruments. Low 2.5V-core static power reduces internal heating in enclosed instruments, easing thermal design within the -40C to +85C industrial envelope.
おすすめ
Secure Embedded Systems
For embedded systems where firmware extraction is a concern, the A54SX16A-1TQG100I provides hardware-level protection: once antifuses are programmed, the interconnect pattern cannot be electrically read out, and there is no external configuration flash to clone. Designers host cryptographic helpers, secure boot-check logic, and license enforcement state machines across the 1452 CLBs. Combined with the instant-on fabric, security checks can run before the host CPU leaves reset. The industrial temperature grade supports deployed outdoor and unattended equipment, and the TQFP-100 footprint allows migration to higher-capacity A54SX32A variants if the trusted logic grows, without PCB respin.

主な差別化要因

設計ノート
The A54SX16A-1TQG100I is one-time programmable (antifuse). There is no design iteration on the same physical part - each programming run consumes a device. Complete thorough simulation (gate-level with timing back-annotation from Libero) before committing hardware. Order engineering quantities with the production build, and keep the programming file under revision control with a checksum tied to the board serial number for traceability.
The 2.5V core supply requires a clean, low-noise rail; the antifuse fabric draws near-zero static current, but dynamic power scales with toggle rate - at 263 MHz operation provide solid 2.5V and 3.3V I/O decoupling (100 nF ceramic per supply pin pair plus bulk 10 uF). Estimate: dynamic power is dominated by clocked cells, so gating unused clocks in the Libero design significantly reduces consumption versus leaving clocks free-running.
The 100-pin TQFP (0.5 mm lead pitch) requires careful PCB footprint adherence to the JEDEC-style TQFP-100 drawing in the SX-A family datasheet; use solder-mask-defined or non-solder-mask-defined pads per the datasheet recommendation. Place 100 nF decoupling capacitors within 3 mm of the power pins. The 1.4 mm package height allows inspection under the package body with angled cameras for AOI coverage of all four lead sides.
