A54SX16-2PQ208I

Overview

The A54SX16-2PQ208I is a nonvolatile Field Programmable Gate Array from the Microsemi SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 24,000 system gates and features 175 user-programmable I/O pins within a 208-pin Plastic Quad Flat Pack (PQFP) package. The device operates at an industrial temperature range of -40°C to +85°C and supports mixed-voltage operation for 2.5 V, 3.3 V, and 5 V I/Os with 5 V input tolerance.

Feature Summary

• Supports hot-swap capabilities and power-up/down friendly operation without voltage sequencing requirements
• Includes dedicated routing resources such as DirectConnect and FastConnect for deterministic timing
• Integrates boundary-scan testing compliant with IEEE Standard 1149.1 (JTAG)
• Features FuseLock security technology to prevent reverse engineering

Applications

• High-speed controllers and address decoding
• Peripheral bus interfaces including 66 MHz PCI compliance
• DSP and co-processor functions
• ASIC alternatives requiring high performance and low power

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the exact speed grade, package type, and temperature rating. Confirm lead-free packaging status if RoHS compliance is required for the manufacturing process. Ensure the component matches the intended application voltage levels and interface standards before procurement.

Selection Notes

Select this model when 24,000 system gates and 175 user I/Os are sufficient for the design logic. The -2 speed grade offers approximately 25% faster performance than the standard grade. Verify that the PQFP package fits the PCB footprint constraints and that the industrial temperature range meets environmental specifications.

Part Context

This component belongs to the Actel/Microsemi SX-A FPGA family, which utilizes metal-to-metal programmable antifuse interconnect elements. The architecture employs a sea-of-modules design with register cells and combinatorial cells arranged in clusters and superclusters to optimize silicon utilization and signal propagation.

Replacement Considerations

Compatible devices within the same capacity include the A54SX16A series variants with different speed grades or packages. Cross-family replacements may require significant redesign due to architectural differences between antifuse FPGAs and volatile SRAM-based devices.
