A54SX32A-1PQG208M

Overview

The A54SX32A-1PQG208M is a nonvolatile Field Programmable Gate Array from the Actel SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 48,000 system gates and supports up to 174 user-programmable I/Os within a 208-pin Plastic Quad Flat Pack (PQFP) package. The device operates at a standard speed grade with internal clock frequencies reaching 350 MHz. It features mixed-voltage I/O support for 2.5 V, 3.3 V, and 5 V standards, including PCI and TTL compatibility. The architecture utilizes a sea-of-modules design with dedicated routing resources like DirectConnect and FastConnect to ensure deterministic timing.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent configuration without external memory.
• Supports hot-swap capabilities and power-up/down friendly operation where supply voltage sequencing is not required.
• Includes IEEE 1149.1 compliant Boundary-Scan Testing with dedicated or flexible JTAG pin configurations.
• Features Actel Secure Programming Technology with FuseLock to prevent reverse engineering and unauthorized access.

Applications

• High-performance logic integration replacing complex CPLDs or gate arrays
• PCI-compliant interface designs requiring 66 MHz system performance
• Systems requiring deterministic timing and full pin-locking capabilities

Procurement Notes

Verify component authenticity through authorized Microchip distributors. Confirm that the ordering suffix corresponds to the specific temperature grade and packaging requirements. Check for end-of-life status or obsolescence notices as availability may be limited. Ensure compliance with export regulations such as EAR if applicable.

Selection Notes

Select this model for applications requiring 48,000 system gates with a 208-pin PQFP footprint. The -1 speed grade offers approximately 15% faster performance than the standard grade. Verify that the commercial temperature range meets environmental needs. Consider the -F grade if slower speeds are acceptable for lower power consumption.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are designed for low-power, high-performance applications. The family includes devices ranging from 12,000 to 108,000 system gates. The A54SX32A variant specifically targets designs needing moderate capacity with robust I/O flexibility and security features inherent to antifuse technology.

Replacement Considerations

Direct replacements include other speed grades within the A54SX32A series, such as the standard speed version or the -F slower version. For higher capacity, the A54SX72A is available in similar packages. Lower capacity options include the A54SX16A. Cross-family migration to newer Microchip FPGA architectures requires significant design re-verification.
