A54SX16P-TQG176 Übersicht
An FPGA (Field Programmable Gate Array) is a semiconductor device containing configurable logic blocks (CLBs) and programmable interconnects that designers configure in the field, sitting above discrete logic and below ASICs in the programmable-logic hierarchy. Unlike fixed-function ASICs, FPGAs allow iterative design, lower non-recurring engineering costs, and faster time to market. The SX-A family uses a sea-of-modules architecture that simplifies design, reduces power consumption, and shortens development cycles for performance-intensive applications.
Key features of the A54SX16P-TQG176 include its sea-of-modules routing architecture, a maximum clock frequency of up to 320 MHz for the fastest speed grade (the base -standard grade is rated at 240 MHz per Jotrin listing), dual supply compatibility of 3.3V and 5V I/O operation with a 3.0V to 3.6V core supply range on P-variants, and 1452 Configurable Logic Blocks (logic cells). The 0.35 um CMOS process provides a proven, mature manufacturing platform.
Technically, the device implements antifuse-free, SRAM/flash-style configuration through Actel/Microsemi's SX-A programmed routing fabric, offering non-volatile-like design flow via Actel Libero/Designer toolchain support. The 176-pin TQFP with 0.5 mm pin pitch suits hand-inspectable, reflow-solderable designs.
Typical applications include industrial control logic, glueless bus interfacing, telecommunications line cards, test equipment state machines, and avionics/defense systems requiring mature, radiation-tolerant-family heritage parts.
Design consideration: verify I/O bank voltage compatibility (3.3V vs 5V tolerant requirements) before finalizing schematics, and budget power dissipation using the Microsemi SX-A power calculator.

Typische Anwendungen
A54SX16P-TQG176 ist geeignet für 6 Anwendungs: Industrial Control Logic, Telecommunications Line Cards, Test and Measurement Equipment, Avionics and Defense Legacy Systems, Bus Interface and Glueless Interfacing, Embedded System Prototyping and NPI.
Industrial Control Logic
The A54SX16P-TQG176 fits industrial control applications because its 1452 CLBs and 147 user I/Os absorb state machines, sequencers, and glue logic that would otherwise occupy dozens of 74-series devices, while the sea-of-modules architecture keeps propagation delays predictable for deterministic control timing. Its 3.3V/5V supply compatibility allows direct interfacing with legacy 5V TTL sensors, PLC backplanes, and relay-driver circuits common on factory floors. Implemented between sensor banks and actuator drivers with the 176-TQFP's 0.5 mm pitch enabling reliable reflow assembly, the device consolidates board area and reduces power versus discrete TTL implementations. For wide-temperature cabinets, pair with the -I industrial variant (-40C to +85C).
Empfohlen
Telecommunications Line Cards
Telecom line cards benefit from the A54SX16P-TQG176's predictable, deterministic timing: the SX-A routing architecture gives consistent propagation delays (sub-ns class, with Hotenda listing 700 ps class performance), simplifying setup/hold closure for framing, multiplexing, and TDM glue logic at line rates within the 240 MHz standard-grade ceiling. The 147 I/Os handle E1/T1 framers, serial links, and backplane interfaces, and 3.3V/5V operation bridges newer 3.3V silicon to legacy 5V line-card rails. Deployed between physical-layer transceivers and backplane connectors, the FPGA absorbs bus-width conversions and protocol adapters without external PAL/GAL devices, cutting BOM count and board rework cycles on mature platform designs.
Empfohlen
Test and Measurement Equipment
In test and measurement instruments, the A54SX16P-TQG176 implements counters, trigger state machines, and pattern generators where the deterministic SX-A fabric outperforms microprocessor-driven approaches for tight event timing. With 1452 CLBs and up to 240 MHz standard-grade clock capability (320 MHz on the -2 speed grade), designs achieve sub-10 ns event resolution in counter/timer front ends. The 147 I/Os directly drive probe multiplexers, range-switching relays, and display interfaces, while 3.3V/5V dual-rail operation simplifies integration into benchtop instruments that retain 5V logic domains. Using the 176-TQFP keeps the part hand-inspectable during instrument service and calibration, an operational advantage for long-support-lifetime laboratory equipment.
Empfohlen
Avionics and Defense Legacy Systems
The Actel-heritage SX-A family has a long qualification history in avionics and defense platforms, and the A54SX16P-TQG176 serves as a sustaining or re-qualification choice for programs designed around the SX architecture. The mature 0.35 um CMOS process offers well-characterized behavior, and the related RTAX radiation-tolerant family shares architectural lineage, easing design reuse between commercial prototypes and space/defense derivatives. In these systems the FPGA typically implements MIL-STD-1553 glue logic, discrete-to-digital interfaces, and redundant-lane switching. The 176-TQFP ceramic-compatible flow and stable, long-lived supply position through Microchip USA and authorized distributors support programs with multi-decade support requirements and strict configuration control of firmware and silicon revisions.
Empfohlen
Bus Interface and Glueless Interfacing
For bus interfacing, the A54SX16P-TQG176 directly accepts 5V TTL and 3.3V LVTTL signals thanks to its dual 3.3V/5V supply support, eliminating level-shift devices when bridging PCI-era, VME, ISA, or custom backplane buses to modern 3.3V controllers. The 147 I/Os provide enough pins to implement full-width 32-bit buses with control strobes and parity, and the 1452 CLBs implement bus arbitration, byte-lane swapping, and wait-state generation with deterministic single-cycle latency. Placed between a legacy backplane connector and a modern processor or memory subsystem, the FPGA replaces dozens of glue-logic packages, cutting board area and improving signal quality through shorter internal routing. Verify per-bank voltage assignment in Libero before routing mixed-voltage nets.
Empfohlen
Embedded System Prototyping and NPI
During new product introduction, the A54SX16P-TQG176 serves as a low-risk prototyping fabric for ASIC-to-be logic or for validating control algorithms in hardware before committing to mask ROM or custom silicon. The sea-of-modules architecture gives predictable timing from the first build, reducing place-and-route iteration risk, and the standard 176-TQFP package mounts on inexpensive 4-layer prototype boards without via-in-pad or heatsink complexity. With 16K-24K system gates, it accommodates microprocessor peripherals, interrupt controllers, and interface bridges typical of embedded platforms. Because the family remains orderable at DigiKey and Mouser as of 2026-09-03, prototypes can be respun without the allocation risk seen on newer FPGAs, supporting stable development schedules.

Designhinweise
Budget power using Microchip's SX-A power calculator before layout: dissipation scales with toggle rate and I/O loading, and the 176-TQFP theta_JA is dominated by the PCB copper pour under the die-attach region. Estimated: with 3.3V core and moderate 25% utilization, expect tens-to-low-hundreds of mW; verify against the datasheet power spreadsheet for your netlist. Provide at least 2 oz copper on the top layer under the package for heat spreading when operating near +70C ambient in commercial variants.
The 176-TQFP has a 0.5 mm pin pitch; use NSMD (non-solder-mask-defined) pads with approximately 0.25 mm pad diameter and a 1:1 or slightly-tapered stencil aperture to avoid solder bridging on the fine-pitch perimeter. Add thermal relief vias to ground planes adjacent to the VCC/GND pin pairs and place 0.1 uF ceramic decoupling capacitors at all four package sides - at minimum 8-12 capacitors distributed around the perimeter plus bulk 10 uF near each supply entry point.
When mixing 5V and 3.3V I/O on this dual-rail-capable FPGA, group same-voltage signals on contiguous banks and keep 5V TTL traces short to limit undershoot below ground; series-terminate 22-33 ohm on long backplane stubs. The SX-A output edges are fast relative to legacy TTL, so ringing on unterminated 20 cm+ traces can violate input thresholds - a series resistor at each driver on bus lines is cheap insurance for first-pass success.
Do not assume speed-grade interchangeability closes timing automatically: replacing a -2 (320 MHz) design build with the standard 240 MHz A54SX16P-TQG176 requires a full static timing re-run in the Designer/Libero toolchain. Also confirm the supply-voltage class: P-grade variants (P1/P2) specify a 3.0V-3.6V range while standard SX-A parts support 3.3V/5V operation - substituting across process grades without checking rails can stress I/O structures.
