A54SX72A-FGG484M

Overview

The Microchip Technology A54SX72A-FGG484M is an antifuse-based Field Programmable Gate Array (FPGA) from the SX-A family. It provides 108,000 system gates and supports up to 360 user-programmable I/O pins within a 484-pin Fine Pitch Ball Grid Array (FBGA) package. The device operates with internal clock frequencies up to 350 MHz and delivers 250 MHz system performance. It utilizes 0.22 μm / 0.25 μm CMOS process technology and features nonvolatile configuration, eliminating the need for external configuration devices.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports mixed-voltage operation including 2.5 V, 3.3 V, and 5 V I/O standards with 5 V input tolerance and drive strength.
• Hot-swap compliant I/Os allowing safe insertion into electrically active systems without degrading host reliability.
• Includes dedicated boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG).

Applications

• High-performance digital signal processing requiring deterministic timing.
• Industrial control systems necessitating hot-swappable hardware interfaces.
• Prototyping complex logic functions previously implemented in gate arrays.

Procurement Notes

Verify the specific suffix 'M' against official documentation to confirm military temperature grade compliance (-55°C to +125°C). Ensure the ordering code matches the required speed grade and package specifications. Confirm RoHS status if lead-free packaging is mandated for the application.

Selection Notes

Select this model for designs requiring high pin counts and robust I/O flexibility. The SX-A architecture offers 100% resource utilization and pin locking. Consider the available speed grades and temperature ranges when finalizing the part number for production environments.

Part Context

This component belongs to the Actel SX-A family of FPGAs, originally developed by Actel Corporation and now managed by Microchip Technology. The SX-A series is characterized by its antifuse technology, which provides high security against reverse engineering and eliminates configuration boot times associated with SRAM-based FPGAs.
