A54SX32A-FGG484I

Overview

The A54SX32A-FGG484I is a Field Programmable Gate Array from the SX-A family, manufactured by Microsemi. It features 48,000 system gates and 2,880 logic modules within a 484-pin Fine Pitch Ball Grid Array package. The device supports up to 249 user-programmable I/Os and includes three global clock networks. It operates on a 0.22 μm / 0.25 μm CMOS antifuse process technology with a maximum internal performance of 350 MHz. The component is rated for industrial temperature ranges (-40°C to +85°C) and supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Hot-swap compliant I/Os allowing safe insertion into electrically active systems without degrading host reliability.
• Configurable weak-resistor pull-up or pull-down capabilities for I/O pins during power-up to ensure deterministic states.
• Supports IEEE Standard 1149.1 (JTAG) boundary-scan testing with dedicated and flexible pin modes.

Applications

• High-performance digital logic integration requiring deterministic timing
• Systems requiring hot-swappable interface capabilities
• PCI-compliant designs operating at 66 MHz

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type, speed grade, and temperature range. Ensure compatibility with Actel Designer software versions for programming and configuration. Confirm RoHS compliance status if required for environmental regulations. Check for any product discontinuation notices or lifecycle changes issued by the manufacturer.

Selection Notes

Select this model based on the requirement for 48,000 system gates and a 484-pin FBGA footprint. Consider the -1 speed grade implied by the suffix for approximately 15% faster performance than standard. Verify that the industrial temperature grade meets the operational environment requirements. Ensure the design utilizes the available 249 user I/Os effectively within the package constraints.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are designed for cost-effective, low-power, high-performance applications. The family utilizes antifuse technology, offering inherent security against reverse engineering due to the difficulty in distinguishing programmed from unprogrammed cells. The SX-A architecture provides a sea-of-modules layout optimized for register/logic mix flexibility.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Alternative packages within the same gate count family may be available. Ensure any replacement maintains the required antifuse technology characteristics and I/O voltage levels.
