A54SX72A-2PQG208

Overview

The A54SX72A-2PQG208 is an antifuse-based Field Programmable Gate Array (FPGA) from the SX-A family, manufactured by Microchip Technology. It features a capacity of 108,000 system gates and 6,036 logic modules. The device operates within a supply voltage range of 2.25V to 5.25V and supports mixed-voltage I/O standards including 2.5V, 3.3V, and 5V. It utilizes a 208-pin Plastic Quad Flat Pack (PQFP) package with 171 user I/Os. The -2 speed grade indicates performance approximately 25% faster than the standard speed variant.

Feature Summary

• Supports hot-swap capabilities for most I/O standards, allowing safe insertion into active systems without power sequencing requirements.
• Features deterministic timing through patented metal-to-metal antifuse interconnects and dedicated routing resources like DirectConnect and FastConnect.
• Includes comprehensive security mechanisms such as FuseLock technology to prevent reverse engineering and unauthorized design access.
• Provides flexible clocking options including global routed clocks and quadrant-specific clock networks for high-performance signal distribution.

Applications

• High-speed data path logic and fast counters requiring low propagation delay
• Systems requiring nonvolatile single-chip solutions without external configuration memory
• Industrial and commercial applications needing mixed-voltage I/O compatibility

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified agents. Confirm that the specific ordering suffix matches the required speed grade and temperature range. Check for end-of-life notices or production change notifications relevant to this part number before finalizing procurement plans.

Selection Notes

Select this model when 108,000 system gates are required in a 208-pin PQFP package. The -2 speed grade is suitable for designs needing approximately 25% higher performance than standard speed devices. Ensure the application supports the 2.25V to 5.25V operating voltage range and utilizes the available 171 user I/Os effectively.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are based on antifuse technology rather than volatile SRAM. The SX-A series offers nonvolatile configuration, meaning the design is permanently stored in the silicon upon programming. This family is designed for cost-effective, high-performance embedded logic applications.

Replacement Considerations

Direct pin-compatible replacements within the same package and speed grade may not be available due to the discontinuation of certain speed grades. Consider evaluating other SX-A variants or newer Microchip FPGA families if availability is critical, ensuring functional equivalence in gate count and I/O configuration.
