A54SX72A-PQ208I

Overview

The A54SX72A-PQ208I is an industrial-grade Field Programmable Gate Array from the Microchip SX-A family, housed in a 208-pin Plastic Quad Flat Pack (PQFP). It provides 108,000 system gates and supports up to 360 user-programmable I/Os. The device operates within a voltage range of 2.25 V to 5.25 V and functions reliably between -40°C and +85°C. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology, enabling nonvolatile configuration without external memory.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance and drive strength.
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Includes dedicated clock resources such as HCLK, CLKA, CLKB, and quadrant clocks for deterministic timing control.

Applications

• High-performance logic integration replacing complex CPLDs or gate arrays
• Hot-swappable system designs requiring safe board insertion
• Mixed-voltage interface applications supporting multiple I/O standards

Procurement Notes

Verify component authenticity through authorized Microchip distributors. Confirm package integrity and pin alignment prior to installation. Ensure design compatibility with the specific PQFP-208 footprint and thermal requirements defined in the datasheet.

Selection Notes

Select this model for designs requiring high gate density and robust security features inherent to antifuse technology. Consider the industrial temperature grade and mixed-voltage capabilities when interfacing with diverse system components.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are characterized by their use of antifuse technology rather than volatile SRAM configurations. The SX-A series offers high performance and security, making it suitable for applications where data retention and protection against reverse engineering are critical.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX72A series, such as A54SX72A-1PQ208I or A54SX72A-2PQ208I, provided timing constraints allow. Cross-family replacements require careful evaluation of logic capacity and I/O compatibility.
