A54SX32A-2PQG208

Overview

The A54SX32A-2PQG208 is an antifuse-based Field Programmable Gate Array from the Microchip SX-A family, housed in a 208-pin Plastic Quad Flat Pack (PQFP) package. It provides 48,000 system gates and 2,880 configurable logic blocks. The device supports mixed-voltage I/O operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance. It features three global clock networks and complies with IEEE 1149.1 Boundary-Scan Testing standards.

Feature Summary

• Supports hot-swap operations for most I/O configurations without requiring supply voltage sequencing.
• Enables deterministic timing through unique local routing resources including DirectConnect and FastConnect.
• Provides nonvolatile single-chip architecture with Actel FuseLock technology to prevent reverse engineering.

Applications

• High-performance digital signal processing systems
• Industrial control applications requiring mixed-voltage interfaces
• Secure embedded designs utilizing antifuse technology

Procurement Notes

Verify the specific speed grade suffix '2' against current manufacturer availability lists, as discontinued grades may affect sourcing. Confirm that the PQFP package remains in production or qualifies for long-term supply agreements. Ensure design files are compatible with the latest Actel Designer software versions.

Selection Notes

Select this component when high-speed internal performance near 350 MHz is required alongside robust security features. Consider the 208-pin PQFP package if board space constraints favor surface-mount QFP over BGA options. Verify that the 48,000 gate capacity aligns with the specific logic density requirements of the target application.

Part Context

This part belongs to the SX-A family of antifuse FPGAs, which utilize metal-to-metal programmable interconnects. The A54SX32A variant specifically offers a balance of logic density and I/O flexibility. The '-2' designation indicates a speed grade approximately 25% faster than the standard version within the same package and temperature range.

Replacement Considerations

Direct pin-compatible replacements within the same package and speed grade should be verified via official Microchip discontinuation notices. Cross-family migration to newer FPGA architectures requires significant schematic and code revalidation due to architectural differences.
