A54SX72A-2FGG256I

Overview

The A54SX72A-2FGG256I is an industrial-grade Field Programmable Gate Array from the SX-A family, featuring 108,000 system gates and a 256-pin Fine Pitch Ball Grid Array package. It supports up to 360 user I/Os with mixed-voltage operation at 2.5 V, 3.3 V, and 5 V. The device operates within a temperature range of -40°C to +85°C and utilizes antifuse technology for nonvolatile configuration.

Feature Summary

• Supports hot-swap capabilities and power-up/down friendly operation without supply voltage sequencing requirements.
• Provides deterministic timing through unique local routing resources including DirectConnect and FastConnect.
• Includes Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.

Applications

• High-performance logic integration requiring low-power operation
• Systems requiring hot-swappable interface compatibility
• Applications needing secure, nonvolatile single-chip FPGA solutions

Procurement Notes

Verify component authenticity by checking markings against official datasheet specifications. Confirm that the ordering suffix matches the required speed grade and temperature range. Ensure proper handling procedures are followed due to moisture sensitivity classification.

Selection Notes

Select this model when 108,000 system gates and 360 user I/Os are required in a 256-pin FBGA package. Choose the -2 speed grade for approximately 25% faster performance than standard devices. Verify industrial temperature range compliance for environments between -40°C and +85°C.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilize metal-to-metal programmable antifuse interconnect elements. The family offers high-density logic modules and dedicated clock networks suitable for complex digital designs requiring deterministic performance.

Replacement Considerations

Compatible alternatives within the SX-A family include A54SX72A-1FGG256I (standard speed) or A54SX72A-FGG256I (slower speed). Verify pinout compatibility and ensure the replacement meets the specific timing and thermal requirements of the original design.

FAQ

What is the maximum number of user I/Os supported by the A54SX72A?

The A54SX72A device supports up to 360 user I/Os when packaged in the 256-pin FBGA configuration.

How does the A54SX72A handle power-up sequences?

The device is power-up/down friendly, meaning VCCA and VCCI do not need to be stable during power-up and can be powered in any order without sequencing requirements.

What security features are included in the SX-A architecture?

The device includes Actel Secure Programming Technology with FuseLock, which prevents unauthorized reading of the bitstream and protects against reverse engineering by hiding security fuses throughout the fabric.
