MPN： A54SX16P-VQG100M ✓ 啟用中A54SX16P-VQG100M 概覽
An FPGA is a reconfigurable (in this case, one-time-programmable antifuse) integrated circuit that implements custom digital logic through a sea of programmable modules. Within the semiconductor hierarchy, the A54SX16P belongs to the Actel SX family, under the FPGA product class, within the programmable logic / application-specific IC domain. The SX family's sea-of-modules architecture delivers gate-level ASIC-like performance without NRE costs or mask charges.
Key features include a 0.35um process technology, system frequencies up to 240 MHz, 81 user-programmable I/O pins supporting 3.3V and 5V signaling, and antifuse interconnect that is inherently non-volatile and highly secure against design extraction. Because configuration is stored in antifuse elements rather than SRAM, the device is live at power-up with no external boot memory, reducing board cost and improving system reliability.
The SX architecture uses a sea-of-modules routing fabric that minimizes interconnect delay, enabling dramatic reductions in design time, power consumption, and time to market for performance-intensive applications such as glue logic consolidation, bus interface bridging, and high-speed state machines.
Typical applications include industrial control systems, communications and networking line cards, avionics and military subsystems requiring secure one-time programming, and high-speed protocol bridging where 240 MHz-class performance is required.
Design consideration: the A54SX16P is one-time programmable; validate the design thoroughly in simulation and, if possible, on a higher-density SX-A SRAM-family prototype before committing to production programming.

典型應用
A54SX16P-VQG100M 適用於 6 應用s: Industrial Control and Automation, Communications and Networking Line Cards, Avionics and Defense Secure Logic, Test and Measurement Instrumentation, Legacy 5V System Migration and Glue Logic Consolidation, Medical Device Control Logic.
Industrial Control and Automation
The A54SX16P-VQG100M fits industrial controllers that need deterministic, instant-on logic with 5V-tolerant I/O. Its 81 user I/Os and dual 3.3V/5V supplies interface directly with legacy PLC sensor and actuator buses, while the 240 MHz system capability handles fast state machines and encoders. Because antifuse configuration is non-volatile, the FPGA begins operating at power-up with no configuration host, improving uptime in factory automation cells. Place it as the glue-logic and sequencing hub between a microcontroller and I/O drivers; the trade-off versus reprogrammable parts is fixed logic, so lock the design after validation.
推薦
Communications and Networking Line Cards
In telecom and datacom line cards, the A54SX16P provides 240 MHz-class logic for framing, deskewing, and protocol bridging between physical interfaces and backplane buses. The sea-of-modules architecture keeps interconnect delays short and predictable, supporting pipelined datapaths that SRAM FPGAs of the era could not match deterministically. Its antifuse fabric also reduces dynamic power versus segmented routing. Use it for address decoding, packet-count statistics, and bus width conversion; at 3.3V I/O it pairs cleanly with PHY devices while 5V tolerance protects against legacy backplane signaling.
推薦
Avionics and Defense Secure Logic
Antifuse FPGAs like the A54SX16P are valued in avionics and defense subsystems because the programmed interconnect cannot be read back, protecting proprietary or mission logic from extraction. Instant-on behavior eliminates configuration-boot vulnerabilities during power sequencing, important in flight control and telemetry paths. The device's low routing capacitance also yields good SEU-adjacent design margins for controlled environments. Deploy it for voter logic, bus interfaces, and safety monitors; plan programming at the authorized facility since one-time programming prevents field rework.
推薦
Test and Measurement Instrumentation
Bench and automated test equipment benefit from the A54SX16P's deterministic timing: counter/timer channels, trigger state machines, and instrument bus glue logic all run with predictable delays from the low-capacitance antifuse fabric. With 81 user I/Os in a compact 100-pin VQFP, it consolidates discrete TTL glue and reduces board area and BOM count. The 240 MHz rating supports high-resolution time-to-digital front ends. Designers should reserve I/O for calibration interfaces because the design cannot be changed after programming.
推薦
Legacy 5V System Migration and Glue Logic Consolidation
Many installed systems mix 5V TTL with 3.3V devices; the A54SX16P's dual 3.3V/5V operation lets it bridge both domains on one chip, absorbing address decoders, bus transceivers' control logic, and interrupt controllers previously built from dozens of 74-series devices. Consolidation reduces board area, assembly cost, and failure points while the non-volatile antifuse configuration removes any need for a configuration PROM, simplifying upgrades of legacy control shelves. Quantify savings by counting replaced SSI/MSI packages against one FPGA plus programming cost.
推薦
Medical Device Control Logic
Portable and benchtop medical instruments use the A54SX16P for deterministic control sequencing, sensor timing, and interface glue where power-up immediacy and predictable latency matter for safety interlocks. Antifuse non-volatility means the interlock logic is active from the instant of power application, with no configuration gap that could allow uncontrolled states. The compact 100-pin VQFP (approximately 14x14 mm class) suits space-limited mainboards, and 5V-tolerant I/O simplifies integration with legacy analog front-end boards commonly retained across instrument generations.

設計說明
The A54SX16P is one-time programmable antifuse silicon: once programmed, the design cannot be erased or reworked. Complete functional simulation, static timing analysis at your speed grade, and design reviews before submitting to programming. If design iteration risk is high, prototype logic on a higher-density SX-A SRAM-based family part first, then migrate the frozen netlist to the A54SX16P for production.
The A54SX16P supports both 3.3V and 5V supply operation; decouple each supply pin with 0.1 uF ceramics placed within a few millimeters of the pin, plus bulk 10 uF per rail. Minimize simultaneous switching on the 81 user I/Os by spreading outputs across banks and adding small series resistors (22-33 ohm) to control ground bounce on 5V-logic edges. Estimated power scales with toggle rate - keep high-activity nodes short-routed in the place-and-route tool.
Use the standard VQFP-100 land pattern (0.5 mm pitch) with a fine-pitch soldering process; inspect with X-ray or AOI since J-leads on VQFP hide solder joints. Reserve programming access per the datasheet's dedicated programming pins, and keep them free of heavy pull-ups that can disturb programming waveforms. The exposed VQFP has no thermal pad, so 81 I/O plus power pins on two layers is generally adequate thermally for this density.
