A54SX72A-2FG256I

Overview

The A54SX72A-2FG256I is an industrial-grade Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It features 108,000 system gates and operates within a temperature range of -40°C to +85°C. The device utilizes a 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V. It is housed in a 256-pin Fine Pitch Ball Grid Array (FBGA) package with 203 user I/Os. The speed grade '-2' indicates approximately 25% faster performance than the standard speed variant.

Feature Summary

• Supports hot-swap operations for most I/O configurations, allowing safe insertion into active systems without power sequencing requirements.
• Provides deterministic timing through unique local routing resources like DirectConnect and FastConnect, ensuring predictable signal propagation.
• Includes Actel Secure Programming Technology with FuseLock to prevent reverse engineering and unauthorized design access.
• Features configurable weak-resistor pull-up or pull-down options for I/O pins during power-up to ensure known states.

Applications

• High-performance logic integration requiring nonvolatile single-chip solutions
• Systems demanding hot-swappable interface capabilities
• Applications requiring secure embedded designs protected against reverse engineering

Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature grade (-40°C to +85°C). Confirm the package type matches the 256-pin FBGA specification. Ensure compliance with export regulations if applicable. Check datasheet revisions for any updates regarding pin assignments or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when 108,000 system gates are required alongside high-speed performance. The '-2' speed grade offers approximately 25% faster operation than standard grades. Consider the 256-pin FBGA package constraints and verify that the 203 available user I/Os meet interface requirements. Ensure the design leverages the mixed-voltage I/O support for 2.5 V, 3.3 V, and 5 V signals.

Part Context

This part belongs to the SX-A Family FPGAs, which utilize metal-to-metal programmable antifuse interconnect elements. The family includes devices ranging from 12,000 to 108,000 system gates. The A54SX72A represents the highest capacity in this specific series, offering four quadrant clocks and extensive routing resources for complex logic implementations.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing Actel Designer software versions if migrating from other SX-A variants such as the A54SX32A or A54SX16A.
