• Supports hot-swap operations and power-up/down sequences without voltage sequencing requirements, ensuring safe insertion into active systems.
• Includes dedicated routing resources such as DirectConnect and FastConnect to minimize propagation delays and maximize logic utilization.
• Integrates boundary-scan testing compliant with IEEE Standard 1149.1 (JTAG) for enhanced diagnostic and verification capabilities.

Applications

• High-performance digital signal processing requiring deterministic timing and low latency.
• Industrial control systems necessitating robust I/O flexibility and mixed-voltage interface support.
• Secure embedded applications leveraging antifuse architecture to prevent reverse engineering and design theft.

Procurement Notes

Verify component authenticity through authorized Microchip distributors due to the availability of counterfeits in the market. Confirm that the specific ordering suffix matches the required speed grade and temperature range, as these parameters define the electrical characteristics and operational limits of the integrated circuit.

Selection Notes

Select this model when a nonvolatile FPGA with high-speed internal routing is required. Ensure the design utilizes the available global clock networks and I/O standards compatible with the 2.5 V, 3.3 V, or 5 V supply rails. Consider the 208-pin PQFP package constraints for PCB layout and thermal management during the initial design phase.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. The family offers a range of capacities from 12,000 to 108,000 system gates, providing scalable solutions for various logic density requirements while maintaining consistent architectural features across the series.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Designers migrating from other FPGA families should evaluate pin compatibility and logic resource equivalence carefully, as the SX-A architecture relies on specific antifuse programming tools and methodologies.
