A54SX08A-2PQG208

Overview

The A54SX08A-2PQG208 is a field-programmable gate array from the SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 12,000 system gates and 768 logic modules (combinatorial cells). The device supports up to 130 user I/Os in a 208-pin plastic quad flat pack (PQFP) package. It operates within a voltage range of 2.25 V to 5.25 V and features mixed-voltage I/O support for 2.5 V, 3.3 V, and 5 V standards. The -2 speed grade delivers approximately 25% faster performance than the standard grade, with internal clock frequencies reaching 350 MHz.

Feature Summary

• Supports hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Features nonvolatile single-chip architecture that prevents reverse engineering and eliminates configuration bitstream interception.
• Includes configurable weak-resistor pull-up or pull-down capabilities for deterministic I/O states during power-up.

Applications

• High-performance digital logic integration requiring fast execution of complex functions
• Systems requiring deterministic timing and pin-locking capabilities
• Applications needing secure design protection against unauthorized access

Procurement Notes

Verify the specific ordering suffixes to confirm temperature grade and packaging compliance. The 'I' suffix indicates industrial temperature range operation. Confirm RoHS status if lead-free packaging is required for assembly processes. Ensure compatibility with existing PCB footprints for the PQFP-208 package dimensions.

Selection Notes

Select this model when 12,000 system gates are sufficient for the design complexity. The -2 speed grade is appropriate for designs requiring higher throughput than the standard version. Verify that the 208-pin PQFP package fits the mechanical constraints of the target application. Consider the mixed-voltage I/O flexibility if interfacing with multiple logic families.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilizes metal-to-metal programmable antifuse interconnect elements. The family offers a sea-of-modules architecture with dedicated routing resources like DirectConnect and FastConnect for optimized signal propagation. Microsemi Corporation acquired Actel, integrating these high-reliability antifuse devices into their broader portfolio.

Replacement Considerations

Compatible alternatives within the same family include the A54SX08A-1PQG208 for standard speed requirements. For higher capacity needs, the A54SX16A series provides increased logic resources in similar packages. Verify pinout compatibility when substituting between speed grades or capacity variants.
