A54SX08A-2PQ208I

Overview

The A54SX08A-2PQ208I is an antifuse-based FPGA from the Microsemi SX-A family, housed in a 208-pin PQFP package. It provides 12,000 system gates and 768 logic modules (CLBs). The device supports up to 130 user-programmable I/O pins and features three global clock networks. Operating within a voltage range of 2.25V to 5.25V, it delivers a typical system performance of 250 MHz with internal clock frequencies reaching 350 MHz. The -2 speed grade offers approximately 25% faster performance than the standard grade. It operates reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports mixed-voltage operation for 2.5 V, 3.3 V, and 5 V I/Os with 5 V input tolerance.
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Includes Actel Secure Programming Technology with FuseLock to prevent reverse engineering and unauthorized access.
• Provides deterministic timing through unique local routing resources like DirectConnect and FastConnect.

Applications

• High-speed controllers and address decoding
• Peripheral bus interfaces including PCI compliance
• DSP and co-processor functions

Procurement Notes

Verify the specific ordering suffix 'G' if RoHS compliant packaging is required, as the base model may default to standard packaging. Confirm the '-2' speed grade designation matches the target frequency requirements. Ensure the 'I' suffix aligns with the necessary industrial temperature operating range for the deployment environment.

Selection Notes

Select this component when a nonvolatile single-chip solution is needed to replace multiple CPLDs or FPGAs. The SX-A architecture is suitable for designs requiring high pin-locking capabilities and full resource utilization. Consider the 0.22 μm / 0.25 μm CMOS process technology for low-power applications requiring fast execution of complex logic functions.

Part Context

This part belongs to the Microsemi SX-A family of Field Programmable Gate Arrays. The family utilizes metal-to-metal programmable antifuse interconnect elements to create permanent low-impedance connections. The A54SX08A variant represents the entry-level capacity within the series, offering 12,000 system gates while sharing the same architectural features as larger devices like the A54SX16A and A54SX32A.

Replacement Considerations

Compatible substitutes include other members of the SX-A family such as the A54SX08A-1PQ208I or A54SX08A-PQ208I, depending on the required speed grade. For higher capacity needs within the same package, the A54SX16A-PQ208I serves as a direct upward migration path.
