A54SX72A-1FG256

Overview

The A54SX72A-1FG256 is a Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It features 108,000 system gates and 6,036 logic modules within a 256-pin Fine Pitch Ball Grid Array (FBGA) package. The device supports up to 203 user I/Os and operates with supply voltages ranging from 2.25 V to 5.25 V. It includes dedicated flip-flops for sequential logic and supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V. The -1 speed grade indicates performance approximately 15% faster than the standard speed variant.

Feature Summary

• Nonvolatile antifuse architecture providing permanent configuration without external memory
• Hot-swap compliant I/Os allowing insertion into active systems without power sequencing
• Deterministic timing through metal-to-metal programmable interconnect elements
• Integrated boundary-scan testing compliant with IEEE Standard 1149.1

Applications

• High-performance digital signal processing requiring deterministic latency
• Industrial control systems utilizing hot-swap capabilities
• Secure embedded applications protected by FuseLock technology
• PCI-compliant interface designs supporting 66 MHz operations

Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation to confirm temperature grade and packaging compliance. Confirm availability status as lead times may vary due to manufacturing changes or discontinuance notices associated with legacy FPGA families.

Selection Notes

Select this component when high gate density and nonvolatile configuration are required in a single-chip solution. Ensure the design utilizes the available quadrant clocks if complex clock distribution across the die is necessary. Verify that the 256-FBGA package dimensions fit the target PCB layout constraints.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which utilize CMOS antifuse technology. The SX-A series is designed for low-power, high-performance applications, offering a cost-effective alternative to traditional gate arrays. The A54SX72A represents the highest capacity device in this specific family lineup.

Replacement Considerations

Direct functional replacements are limited due to the proprietary antifuse architecture. Consider reviewing the broader Microchip FPGA portfolio for modern alternatives, though pinouts and programming tools will differ significantly.
