A54SX32A-TQG100

Overview

The A54SX32A-TQG100 is a Field Programmable Gate Array from the Microchip SX-A family, featuring 48,000 system gates and 2,880 logic modules. It supports up to 81 user-programmable I/O pins within a 100-pin Thin Quad Flat Pack (TQFP) package. The device operates on a 0.22 μm / 0.25 μm CMOS antifuse process, enabling internal clock frequencies up to 350 MHz and system performance of 250 MHz. It accommodates mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V with 5 V input tolerance.

Feature Summary

• Supports hot-swap compliant I/Os allowing power-up/down without voltage sequencing requirements.
• Includes deterministic timing architecture with DirectConnect and FastConnect routing resources.
• Provides IEEE 1149.1 (JTAG) boundary-scan testing compliance for in-system diagnostics.

Applications

• 66 MHz PCI compliant designs
• High-performance state machines and fast counters
• Data path logic integration

Procurement Notes

Verify the specific suffix 'I' or 'A' against the required temperature grade before ordering. Confirm the package type matches the design footprint. Check for RoHS compliance status if environmental regulations apply. Ensure the speed grade meets the target frequency requirements. Validate that the manufacturing source aligns with project specifications.

Selection Notes

Select this component for applications requiring high-density logic in a compact surface-mount package. Consider the 48K gate capacity for complex digital control tasks. Evaluate the mixed-voltage I/O capabilities for interfacing with diverse system components. Assess the nonvolatile nature for simplified configuration management compared to SRAM-based FPGAs.

Part Context

This part belongs to the Actel SX-A FPGA family, which utilizes antifuse technology. The A54SX32A designation indicates 48,000 system gates. The TQG100 suffix specifies the 100-pin TQFP package and commercial temperature range. This family is known for deterministic timing and security features inherent to antifuse architectures.

Replacement Considerations

Direct pin-compatible replacements within the same package are limited due to the specific antifuse architecture. Review the A54SX32A datasheet for other speed grades or temperature variants. Cross-reference with newer Microchip FPGA families for modern alternatives if antifuse technology is not strictly required.
