A54SX16P-TQG176I Visão geral
An FPGA (Field Programmable Gate Array) is a semiconductor device containing a fabric of configurable logic blocks (CLBs) and programmable interconnects that the designer programs after manufacturing. Within the programmable logic hierarchy, the SX family sits among antifuse-based, one-time-programmable FPGAs, which contrasts with SRAM-based FPGAs that require configuration storage. The SX family uses a sea-of-modules architecture that simplifies design implementation, reduces design cost and power consumption, and shortens time to market for performance-intensive applications.
Key features include 16K usable gates with 924 logic cells, up to 147 programmable I/O pins supporting both 3.3V and 5V signaling, and a 240 MHz maximum system toggle frequency made possible by the 0.35 um process and the fast, predictable antifuse interconnect structure. Because configuration is stored in antifuse elements, the device is immune to configuration-stream corruption, a meaningful reliability benefit in harsh or long-lifetime systems.
Architecturally, the A54SX16P organizes logic into 1452 Configurable Logic Blocks arranged in the sea-of-modules fabric, with routing implemented through metal-to-metal antifuse links that add minimal RC delay. This yields deterministic, timing-driven performance that design tools can predict accurately without re-configuration overhead.
Typical applications include industrial control and automation, aerospace and defense glue logic and co-processing, telecommunications line-card functions, and legacy 5V system bridging, where the 3.3V/5V mixed-supply capability and industrial temperature range are decisive.
When designing with this device, note that antifuse programming is permanent: verify the design in simulation and, if possible, validate on a companion SRAM-family device before committing. Power distribution and decoupling on both VCC rails should follow Microchip/Microsemi application guidance.

Aplicações típicas
A54SX16P-TQG176I é adequado para 6 aplicaçãos: Industrial Control and Automation, Aerospace and Defense Logic, Telecommunications Line Cards, Legacy 5V System Bridging, Test and Measurement Instrumentation, Security and Surveillance Equipment.
Industrial Control and Automation
The A54SX16P-TQG176I fits industrial control and factory automation because its 16K gates and 924 cells provide enough fabric for state machines, interface bridging, and motor-control sequencers, while the 147 5V-tolerant I/O directly connect to legacy 24V-domain sensors through standard level-shifting front ends. The industrial (I) temperature grade supports -40C-class cabinet environments common on factory floors. Because the antifuse configuration is one-time-programmable and immune to single-event configuration upset from electrical noise, control logic retains its function through power brownouts that would force an SRAM FPGA to reload. Placed between a PLC backplane and local I/O cards, the device runs glue logic at deterministic timing derived from its 0.35 um process and 240 MHz-class toggle capability; the trade-off is that any functional change requires a new programmed device rather than a field update.
Recomendado
Aerospace and Defense Logic
Antifuse FPGAs such as the A54SX16P-TQG176I are historically favored in aerospace and defense subsystems because the one-time-programmed configuration cannot be corrupted by radiation-induced configuration memory upset, and the device requires no external configuration flash at power-up. With 16,000 gates, 924 cells, and 147 I/O, it implements payload sequencing, telemetry encoding, and bus-interface glue logic at toggle rates up to 240 MHz-class. The industrial temperature grade and wide 3.3V/5V mixed-supply operation simplify integration into mixed-rail avionics boards. In typical use the FPGA sits between a processor or microcontroller and mission-specific analog or digital peripherals, trading SRAM-family reprogrammability for deterministic timing and startup simplicity. Designers needing higher radiation tolerance later migrate within Microchip's portfolio to RTAX-series radiation-t hardened FPGAs, reusing similar tool flows.
Recomendado
Telecommunications Line Cards
The A54SX16P-TQG176I suits telecommunications line-card designs that require flexible interconnect logic between framers, physical-layer devices, and backplanes. Its 147 user I/O with 5V tolerance interfaces directly to legacy 5V-line-card components while the 3.3V core rail supports denser modern logic, reducing the need for discrete level translators. The 240 MHz-class toggle rate and 0.35 um antifuse fabric handle framing, multiplexing, and alarm-scanning logic at T1/E1 and lower-rate SONET auxiliary functions with deterministic timing that simplifies static timing sign-off. Because configuration is fixed at programming, line cards power up instantly in a known-good state, an operational advantage in carrier equipment where uptime and hot-standby behavior are monitored. Designers should budget I/O bank current per Microchip guidance and decouple both rails locally at the TQFP.
Recomendado
Legacy 5V System Bridging
Many installed industrial, test, and transportation systems still run 5V logic, and the A54SX16P-TQG176I addresses this niche directly: it operates on 3.3V and 5V supplies per Jotrin and FPGAkey listings, so 5V-tolerant inputs accept TTL-level signals without clamping diodes or resistor dividers, and outputs can drive 5V logic thresholds. Within the upgrade path, the FPGA typically sits as the bridge between a legacy 5V backplane (VME-style or parallel bus signals) and a newer 3.3V processor module, implementing bus multiplexing, address decoding, and handshaking in 16K gates. The 176-pin TQFP with 147 I/O provides sufficient pin count for wide parallel buses that modern low-pin FPGAs cannot serve. The key trade-off is one-time programmability: signal-integrity and timing corners should be fully verified in simulation before programming, since the antifuse fabric cannot be reconfigured after deployment.
Recomendado
Test and Measurement Instrumentation
Bench and rack instrumentation benefits from the A54SX16P-TQG176I's predictable, timing-deterministic antifuse fabric when implementing trigger engines, counter/timer channels, and bus decoders. With 16K gates, 924 cells, and a 240 MHz-class toggle rate, the device resolves timing events at fine granularity, while 147 I/O connect to front-end acquisition circuitry, relay banks, and display interfaces across both 3.3V and 5V rails. The industrial temperature grade covers unconditioned test-cell environments. Typical topology places the FPGA between analog front ends (ADCs and amplifiers) and the system processor, offloading hard-real-time capture and event counting that software cannot guarantee. The one-time-programmable nature is acceptable in instruments where logic is frozen at design release; teams that iterate firmware-instrument logic frequently should instead consider SRAM-based families. Local decoupling on both rails preserves measurement noise floors.
Recomendado
Security and Surveillance Equipment
In industrial security controllers, access-control panels, and surveillance system interface boards, the A54SX16P-TQG176I implements sensor-scan logic, alarm arbitration, and video-matrix switching control within its 16K-gate fabric. The 147 I/O at 5V tolerance connect directly to legacy PIR contacts, door loops, and relay drivers without additional translation stages, and the 240 MHz-class fabric timestamps events with deterministic latency, critical for audit-grade access logs. The industrial temperature grade supports outdoor cabinet installations from cold climates to hot plant rooms. Instant-on antifuse configuration means the controller is armed within milliseconds of power application, with no configuration-device load time that could leave a security window open during startup. The design trade-off is that algorithm updates require programmed-device replacement, so systems should stock spare programmed units or reserve the -2 speed grade (A54SX16P-2TQG176I) for future timing margin.

Notas de projeto
The A54SX16P-TQG176I requires both 3.3V and 5V rails. Decouple each rail at the TQFP with at least one 0.1 uF ceramic per supply pin group plus bulk 10 uF per rail. Estimated: SX-family static current is low, but dynamic power scales with toggle rate and I/O loading; at 147 I/O driving 5V loads at moderate frequency, I/O power can dominate the power budget, so compute per the Microchip SX power estimation spreadsheet rather than assuming worst-case values.
The device is antifuse (one-time programmable): once programmed, the logic is permanent. Verify the design with post-layout simulation and confirm timing at the correct speed grade before submitting programming files. Ordering the -2 speed grade (A54SX16P-2TQG176I) adds timing headroom for the same footprint, which is cheaper than respinning a board after a timing failure on the standard grade.
The 176-pin TQFP uses fine-pitch gull-wing leads; specify a 0.5 mm-class footprint per the Microchip/Microsemi package drawing and use solder-mask-defined or non-solder-mask-defined pads per IPC guidance in the datasheet package section. Route 5V-tolerant I/O away from clock traces to reduce coupling, and tie unused I/O to a defined state in the design rather than leaving them floating, which improves noise immunity and reduces standby current.
