A54SX32-2BGG329

Overview

The A54SX32-2BGG329 is a nonvolatile Field Programmable Gate Array from the Actel SX-A family, featuring 48,000 system gates and 2,880 logic modules. It operates with an internal clock frequency of up to 350 MHz and supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V. The device provides up to 249 user-programmable I/O pins and utilizes a 0.22 μm / 0.25 μm CMOS antifuse process. It is housed in a 329-pin Plastic Ball Grid Array (PBGA) package and supports commercial temperature ranges.

Feature Summary

• Supports hot-swap capabilities for simplified system integration without supply voltage sequencing requirements.
• Provides deterministic timing through patented metal-to-metal antifuse interconnects and dedicated routing resources.
• Includes IEEE 1149.1 compliant Boundary-Scan Testing for enhanced diagnostic and verification capabilities.

Applications

• 66 MHz PCI compliant single-chip solutions
• Low-power high-performance designs requiring nonvolatile configuration
• Systems requiring mixed-voltage operation with 5 V input tolerance

Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors or direct channels. Confirm that the specific ordering suffix matches the required speed grade, package type, and temperature range specifications before procurement. Ensure compliance with relevant environmental regulations applicable to the intended deployment region.

Selection Notes

Select this model when 48,000 system gates and 249 I/Os are required within a 329-pin BGA footprint. Consider the -2 speed grade for performance levels approximately 25% faster than standard variants. Verify that the application environment aligns with the commercial temperature rating and mixed-voltage I/O support capabilities.

Part Context

This component belongs to the Actel SX-A FPGA family, which utilizes antifuse technology for permanent, nonvolatile configuration. The SX-A series is designed to replace multiple CPLDs and gate arrays in complex digital logic applications, offering high density and low power consumption compared to previous generation devices.

Replacement Considerations

Direct functional replacements within the same package and pinout may include other speed grades of the A54SX32A series, such as the A54SX32-1BGG329 or A54SX32-BGG329, provided timing constraints allow for slower performance. Cross-family migration requires schematic and design rule checks.
