A54SX16P-VQG100I Übersicht
A field-programmable gate array (FPGA) is a semiconductor device containing a fabric of configurable logic blocks (CLBs) and programmable interconnects that the designer configures after manufacturing, sitting within the programmable logic hierarchy between CPLDs and large system-on-chip FPGAs. The SX family uses Actel's sea-of-modules architecture combined with antifuse one-time-programmable (OTP) technology, which simplifies design time, reduces power consumption, and provides inherent resistance to configuration corruption from radiation or power cycling - no external configuration ROM is required.
Key features include a 240 MHz toggle rate enabled by the 0.35um process, 16K usable gates for mid-density glue logic, state machines and bus interfacing, and dual 3.3V/5V I/O compatibility for bridging legacy 5V systems with modern 3.3V logic. The antifuse fabric also offers low static power and zero configuration-load time at power-up, a distinct advantage over SRAM FPGAs.
Technically, the device's sea-of-modules architecture provides predictable routing delays, beneficial for timing-critical designs. The 81 user I/O on the 100-pin VQFP give a 0.5 mm-pitch, 14x14 mm-class footprint suitable for compact industrial boards.
Typical applications include industrial glue logic and bus bridging, military/avionics systems where OTP configuration integrity matters, telecommunications line cards, and legacy design sustainment for discontinued SRAM FPGA platforms.
Design consideration: because the SX family is one-time programmable, verify the design thoroughly in simulation before programming; there is no in-system reconfiguration.

Typische Anwendungen
A54SX16P-VQG100I ist geeignet für 6 Anwendungs: Industrial Glue Logic and Bus Bridging, Avionics and Defense Program Sustainment, Telecommunications Line Cards, Legacy Design Sustainment and Obsolescence Management, Test and Measurement Equipment, Security and Surveillance Control Logic.
Industrial Glue Logic and Bus Bridging
The A54SX16P-VQG100I fits industrial glue-logic consolidation because its 16,000 gates, 924 logic cells, and 81 user I/O absorb address decoders, bus transceivers, state machines, and interrupt controllers that would otherwise occupy multiple 74-series devices. The 3.3V/5V I/O compatibility is decisive here: the FPGA can directly interface legacy 5V TTL backplanes while its internal core runs at 3.3V, eliminating level-shift ICs. The Actel sea-of-modules architecture gives deterministic routing delays, so timing across the bus interface is predictable without iterative place-and-route tuning. Because the antifuse fabric configures instantly at power-up with no external boot device, the bridge logic is active within microseconds of system reset - important in factory equipment with short reset windows. Deployed between a microprocessor local bus and peripheral cards, it consolidates board area and improves reliability by replacing 10-20 discrete MSI devices with one RoHS-compliant 100-pin VQFP.

Avionics and Defense Program Sustainment
Antifuse FPGAs like the A54SX16P-VQG100I are historically favored in avionics and defense platforms because the one-time-programmed configuration cannot be upset by radiation-induced configuration flips, power glitches, or SEU events that plague SRAM FPGAs. The 16K-gate density suits flight-critical functions such as discrete-to-digital signal conditioning, ARINC bus interface support logic, and built-in-test sequencers. Instant-on configuration with no configuration PROM removes a single-point failure common to SRAM architectures, and the low static power of 0.35um CMOS antifuse fabric suits conduction-cooled or battery-backed modules. With the device now at End of Life per Microchip PCN CBOL-27QNJT614, program offices should place last-time buys against 100-pin VQFP sockets, or qualify the same-die A54SX16P-2VQG100 variant, before remaining distributor stock at DigiKey and TrustedParts brokers is exhausted. Re-qualification burden is minimized by staying within the SX pin-compatible family.

Telecommunications Line Cards
In telecom line-card designs, the A54SX16P-VQG100I implements framing logic, alarm scanning, LED/relay drivers, and backplane handshake state machines across its 81 user I/O. The 240 MHz toggle capability comfortably covers T1/E1-class and backplane clock domains, while the sea-of-modules fabric provides uniform, predictable routing delays for the timing verification required in carrier equipment. The 100-pin VQFP's 0.5 mm pitch and roughly 14 mm body fit the tight vertical card pitch of telecom shelves, and the industrial -40C to +85C rating covers uncontrolled central-office and outdoor plant environments. Because the antifuse configuration is immune to configuration corruption and needs no boot ROM, line cards return to service instantly after hot-swap power events - a practical availability benefit. Its 3.3V/5V I/O tolerance also lets one device bridge legacy 5V backplane signaling and 3.3V framer ICs without external translators, simplifying mixed-voltage card designs.

Legacy Design Sustainment and Obsolescence Management
A primary modern use of the A54SX16P-VQG100I is sustaining installed equipment whose original programmable logic - whether an SX FPGA itself or a discontinued SRAM/CPLD design - is no longer manufactured. The 16K-gate capacity and 81 I/O reproduce typical 1990s-era CPLD and small-FPGA functions, and the antifuse OTP nature means a programmed replacement device is functionally frozen, exactly matching the original design without firmware-management overhead. Engineering teams port the original design through Microchip Libero/Designer tools, program new devices, and drop them into the unchanged 100-pin VQFP footprint. Because Microchip has issued EOL notification CBOL-27QNJT614 for this catalog number, lifetime buys are the recommended strategy: secure the calculated end-of-program quantity now from DigiKey, Mouser, or authorized brokers. Where stock is insufficient, the same-die A54SX16P-2VQG100 and A54SX16-VQG100I variants on the identical footprint extend supply without PCB respin.

Test and Measurement Equipment
Bench and automated test equipment benefits from the A54SX16P-VQG100I's deterministic timing: the 240 MHz-capable 0.35um CMOS fabric and uniform sea-of-modules routing let engineers define precise trigger pipelines, counter/timer chains, and fixture handshake logic with stable, repeatable propagation delays across units. Its 81 user I/O drive fixture relays, multiplexers, and status indicators, while 3.3V/5V I/O tolerance interfaces both modern controllers and legacy 5V instrument buses on one device. Instant-on antifuse configuration means the tester is operational the moment power is applied - no configuration download delay before the first DUT can be stimulated, which matters in high-throughput production testing. The industrial temperature rating supports non-conditioned factory floors. Since the part is one-time programmable, design changes require new devices; keep spare programmed units, and note the EOL status per Microchip PCN CBOL-27QNJT614 when planning test-platform maintenance cycles.

Security and Surveillance Control Logic
Surveillance and access-control hardware uses the A54SX16P-VQG100I for sensor-matrix scanning, relay and lock driver sequencing, tamper-switch debounce logic, and camera power-cycling controllers across its 81 user I/O. The antifuse architecture contributes to system integrity: because the configuration is physically programmed and cannot be reloaded or modified in the field, the logic cannot be tampered with via configuration attacks that threaten SRAM FPGAs - a meaningful security property for access-control panels. Instant power-up configuration with no external boot device ensures the controller is protecting the site immediately after power restoration following an outage. The 16K-gate capacity and 240 MHz capability handle alarm-processing state machines with margin, and the 3.3V/5V I/O interfaces both legacy 12V/5V sensor signaling through appropriate buffers and modern 3.3V microcontrollers. Industrial temperature rating suits unheated gate and perimeter installations.

Designhinweise
The A54SX16P-VQG100I is one-time programmable (antifuse). There is no field reconfiguration: any design change requires a physically new device. Complete thorough functional simulation and timing closure in Microchip Libero/Designer before programming production units. Additionally, this catalog number is End of Life per Microchip PCN CBOL-27QNJT614 - calculate end-of-life quantities now and place last-time buys with DigiKey or authorized brokers before stock depletes, or pre-qualify the same-footprint A54SX16P-2VQG100 / A54SX16-VQG100I variants.
The device operates from 3.3V core/I-O with 5V-tolerant inputs on the SX 'P' variant. Decouple each VDD pin pair on the 100-pin VQFP with at least 0.1uF ceramic capacitors placed within 2-3 mm of the pin, plus one bulk 10uF capacitor per device. Antifuse FPGAs have low static current but dynamic I/O switching current can be significant with 81 I/O toggling; a solid ground return via the VQFP thermal plane is essential. Estimated: 81 outputs at 20 pF each toggling at 50 MHz would drive meaningful transient current - budget accordingly.
The VQG100 package uses a 0.5 mm lead pitch on a roughly 14x14 mm body - inspect solder joints with X-ray or AOI, as fine-pitch QFP bridging is the most common assembly defect. Follow the SX family datasheet land-pattern recommendation exactly, and tie unused user I/O to a defined logic state (inputs with pull-up/pull-down per the Actel design guidelines) rather than leaving them floating, to avoid uncontrolled static current and noise susceptibility. Program devices before or after reflow per the Microchip programming-service flow.
