MPN: A54SX16-2VQG100 ✓ פעילA54SX16-2VQG100 סקירה
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. Within the programmable logic hierarchy, the A54SX16 sits at the FPGA level above CPLDs and below large system-on-chip FPGAs, making it a classic glue-logic integration and high-speed state-machine device. The Actel SX family pioneered a sea-of-modules architecture that delivers ASIC-like performance and integration without the NRE cost or lead time of a masked ASIC.
Key features of the A54SX16-2VQG100 include antifuse-based one-time programmable configuration, which is inherently non-volatile, immune to configuration readback attacks, and removes the need for an external boot flash. The 0.35 um process with sea-of-modules routing yields deterministic, short interconnect delays that support the family's rated clock rates. Dual 3.3V/5V supply support simplifies migration of legacy 5V designs into mixed-voltage systems.
Technically, the device contains 924 logic cells organized as 1452 modules per the SX module architecture, and the -2 speed grade denotes the faster of the standard commercial speed bins. Because configuration is stored in antifuse elements rather than SRAM, the A54SX16 powers up instantly with no configuration time, a decisive advantage in control, avionics-adjacent industrial, and telecommunications line-card applications where instant-on behavior is required.
Typical applications include industrial automation controllers, telecommunications and networking line cards, defense and aerospace subsystem upgrades, and high-speed state machines replacing multiple TTL/CMOS glue-logic devices. The 100-TQFP footprint with 81 I/O offers a good balance of pin count and board area.
Design considerations: the SX family is one-time programmable, so functional changes require a new device rather than a reflash; allocate engineering time for verification before committing boards. Estimated power depends heavily on toggle rates, so use the manufacturer power calculator during budgeting.

יישומים טיפוסיים
A54SX16-2VQG100 מתאים עבור 6 יישוםs: Industrial Automation Controllers, Telecommunications Line Cards, Defense and Aerospace Subsystem Upgrades, High-Speed State Machines and Glue Logic Integration, Test and Measurement Instrumentation, Battery-Powered and Portable Data Acquisition.
Industrial Automation Controllers
The A54SX16-2VQG100 fits industrial controller designs that need deterministic, high-speed logic with instant-on behavior. Its 16,000 gates and 924 logic cells integrate state machines, encoders, and interface glue logic that would otherwise occupy dozens of 74-series devices, and the antifuse configuration means the controller is active the moment power is applied with no configuration boot delay. The dual 3.3V/5V supply domains (3V-3.6V and 4.75V-5.25V) allow direct interfacing with legacy 5V TTL sensors and 3.3V microcontrollers on the same board. The commercial 0C to +70C rating suits factory-floor cabinets with active ventilation. Because the device is one-time programmable, freeze the logic design before production and reserve engineering units for field validation of timing at the -2 speed grade.

Telecommunications Line Cards
Telecom line cards historically built around 5V backplane signaling benefit directly from the A54SX16-2VQG100's dual-domain operation across 3V-3.6V and 4.75V-5.25V. The SX family's sea-of-modules architecture and 0.35 um process deliver deterministic interconnect delays supporting the family's rated performance up to 320 MHz, sufficient for framer/PHY glue logic, HDLC controllers, and backplane arbitration. The 81 user I/O on the 100-TQFP handle per-channel signaling, alarms, and jtag-boundary functions in a compact 14x14 mm surface-mount footprint that eases reflow on high-density cards. Non-volatile antifuse configuration eliminates the configuration PROM that SRAM FPGAs require, improving card availability and reducing bill-of-materials count. Verify AC timing at the -2 speed grade against the backplane protocol before release.
מומלץ
Defense and Aerospace Subsystem Upgrades
Defense maintainers frequently sustain aging platforms whose original ASICs or EPLDs are obsolete; the A54SX16-2VQG100 is a common retrofit because its antifuse configuration is immune to configuration readback, supporting program-security requirements, and its dual 3.3V/5V supplies allow drop-in replacement of legacy 5V programmable logic on unchanged boards. The sea-of-modules architecture provides ASIC-like timing determinism, simplifying worst-case timing analysis for safety-relevant logic. The 100-TQFP (14x14 mm) package matches many legacy socket footprints and supports solder rework in depot conditions. For extended-temperature platforms, the same die is available as A54SX16-VQG100I rated -40C to +85C, enabling one schematic to serve both commercial and industrial variants. Note that OTP technology requires strict design sign-off since field updates require a physical device swap.
מומלץ
High-Speed State Machines and Glue Logic Integration
Replacing multiple TTL/CMOS glue devices is the classic SX use case, and the A54SX16-2VQG100 executes it well: 16,000 gates and 924 cells absorb address decoders, bus arbiters, wait-state generators, and interrupt controllers that previously consumed 20 or more SSI/MSI packages. Deterministic sea-of-modules routing keeps pin-to-pin delays short and predictable, and the -2 speed grade supports system clocks well into the tens of megahertz with family performance rated up to 320 MHz for critical paths. Instant-on antifuse configuration means glue logic is functional before the host CPU completes reset, which matters for bus-hold and reset-contoller roles. Consolidation cuts board area, power, and assembly cost while the 100-TQFP's 81 I/O provide ample pin budget. Estimate dynamic power with the manufacturer calculator using actual toggle rates.
מומלץ
Test and Measurement Instrumentation
Bench and rack instruments need precisely timed trigger chains, counter/timer arrays, and interface logic with deterministic delays, which the A54SX16-2VQG100 provides through its sea-of-modules architecture and -2 speed grade timing. The antifuse configuration eliminates configuration-time jitter at power-up, so the instrument is measurement-ready immediately, a real advantage in automated test environments cycling power frequently. The 81 user I/O support multi-channel trigger I/O, and the dual 3.3V/5V domains bridge modern 3.3V control circuitry with legacy 5V signal conditioning front ends. The commercial 0C to +70C rating matches laboratory environmental specifications. Because the device is one-time programmable, calibrate timing in simulation and validate on engineering units before programming production devices; design changes then require new devices rather than reflashing.
מומלץ
Battery-Powered and Portable Data Acquisition
Portable and battery-powered acquisition systems select the A54SX16P family members (A54SX16P-VQG100 in the same 100-TQFP footprint) when power is the constraint, but the A54SX16-2VQG100 remains appropriate where its logic integrates the entire acquisition sequencer and removes a microcontroller's real-time burden. The antifuse draw is effectively zero in static terms compared with SRAM FPGAs that maintain configuration memory, and the sea-of-modules process reduces dynamic consumption per Microchip's architecture notes. The 14x14 mm TQFP conserves board area in handheld enclosures, and the 81 I/O connect multiple sensor channels directly. For lowest power in this footprint, populate the A54SX16P variant without PCB change. Use clock gating in the RTL and the manufacturer's power estimator with realistic toggle rates to confirm battery budget compliance before layout freeze.

הערות תכנון
Dual supply domains are the defining power consideration: connect VCCI banks to 3.3V or 5V per I/O standard and VDD to the core supply, following the 54SX datasheet power-pin connection rules. Estimated: dynamic power scales linearly with toggle rate, so a state machine clocked at 50 MHz with 30% activity draws a small fraction of the 320 MHz worst case - use the Microchip SX power calculator with your actual utilization rather than a single datasheet number. Decouple each supply pin pair with 0.1 uF ceramic plus bulk 10 uF capacitance placed within a few millimeters.
The 100-TQFP (14x14 mm) has 0.5 mm pitch leads; specify a solder-mask-defined footprint per the datasheet mechanical drawing and use a no-clean or water-wash profile compatible with the package body. Fan out with 0.2 mm via-in-pad or dogbone escapes on a standard 4-layer stack, reserving one inner layer as a solid ground plane for signal return integrity. Because the device is surface mount with leads on all four sides, inspect with X-ray or AOI at reflow, not visual-only, to catch bridging on the fine-pitch edges.
The SX family is one-time programmable: there is no reflash path, so any post-production logic change consumes a new device. Lock the RTL and run full simulation sign-off (timing closure at the -2 grade with worst-case corners) before submitting devices to programming. Second pitfall: do not assume -2 timing margins transfer to the standard speed grade if you substitute A54SX16-VQG100 for this part during a shortage - re-run static timing. Finally, respect the 0C to +70C commercial rating; industrial deployments need the A54SX16-VQG100I.
