A54SX32A-1FG484I

Overview

The A54SX32A-1FG484I is an industrial-grade Field Programmable Gate Array from the Microsemi SX-A family, utilizing antifuse technology. It provides 48,000 system gates and 2,880 configurable logic blocks within a 484-pin Fine Pitch Ball Grid Array package. The device supports up to 249 user-programmable I/O pins and operates at a maximum system frequency of 250 MHz with internal performance reaching 350 MHz. It functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports hot-swap capabilities for safe insertion into active systems without power sequencing requirements.
• Features deterministic timing through metal-to-metal antifuse interconnects and dedicated routing resources.
• Includes IEEE 1149.1 compliant boundary-scan testing for in-system diagnostic verification.

Applications

• High-performance digital signal processing
• Industrial control systems requiring hot-swap functionality
• Complex state machine implementations

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Ensure compatibility with existing design tools and verify that the antifuse-based architecture meets long-term availability requirements for the intended application lifecycle.

Selection Notes

Select this component when high-speed deterministic logic is required alongside robust security features. The SX-A architecture offers full pin-locking capabilities, allowing designers to finalize PCB layouts early in the development cycle while maintaining complete resource utilization.

Part Context

This part belongs to the Actel SX-A FPGA family, which utilizes nonvolatile antifuse technology. Unlike volatile SRAM-based FPGAs, these devices retain their configuration permanently upon programming, eliminating the need for external configuration memory chips.

Replacement Considerations

Cross-reference with other speed grades or package options within the A54SX32A series if pin counts or thermal constraints differ. Verify functional equivalence with newer Microchip FPGA families if long-term supply continuity is a priority.
