A54SX72A-PQ208M

Overview

The A54SX72A-PQ208M is a nonvolatile FPGA from the Actel SX-A family, fabricated on 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 108,000 system gates and supports up to 360 user-programmable I/O pins within a 208-pin PQFP package. The device features 6,036 dedicated flip-flops and operates with internal clock frequencies up to 350 MHz. It supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V, including 5 V input tolerance and drive strength. The component includes four quadrant clocks and complies with IEEE Standard 1149.1 for boundary-scan testing.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports hot-swappable I/O configurations allowing power-up/down in any order without supply voltage sequencing requirements.
• Features deterministic timing through unique local routing resources including DirectConnect and FastConnect modules.
• Includes Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.

Applications

• High-performance logic integration requiring deterministic timing and fast counters
• Systems requiring hot-swap capability and cold-sparing redundancy
• Secure applications needing protection against invasive and noninvasive attacks

Procurement Notes

Verify the specific speed grade suffix associated with the PQ208M package variant, as standard speed grades are discontinued. Confirm temperature grade availability (Commercial, Industrial, Automotive, or Military) matches the application environment. Check for RoHS compliance status if lead-free packaging is required for current manufacturing standards.

Selection Notes

Select this device when high gate density and mixed-voltage I/O flexibility are required. Ensure the design utilizes the available quadrant clocks if distributed clocking across the die is necessary. Consider the nonvolatile nature of the antifuse architecture for simplified board design by eliminating external configuration memory components.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are designed for cost-effective, low-power, high-performance designs. The SX-A series offers a sea-of-modules architecture optimized for register/logic mix, providing significant improvements in time-to-market compared to traditional gate arrays or multiple CPLDs.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The -3 speed grades have been discontinued. Verify compatibility with existing Actel Designer software tools for place-and-route implementation.
