A54SX72A-1FGG484

Overview

The A54SX72A-1FGG484 is a Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It features 6036 Configurable Logic Blocks (CLBs) and 4024 dedicated flip-flops, providing up to 108,000 system gates. The device operates with a maximum internal clock frequency of 350 MHz and supports user I/Os up to 360 pins. It utilizes a 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V. The component is housed in a 484-pin Fine Pitch Ball Grid Array (FBGA) package.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports hot-swap compliant I/Os allowing power-up/down without voltage sequencing requirements.
• Includes boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG).
• Features Actel Secure Programming Technology with FuseLock to prevent reverse engineering.

Applications

• High-performance logic integration requiring deterministic timing.
• Systems requiring nonvolatile configuration without external bitstream memory.
• Applications needing mixed-voltage I/O standards including 3.3V/5V PCI and 5V TTL.

Procurement Notes

Verify the specific speed grade suffix '-1' corresponds to approximately 15% faster performance than standard speed. Confirm the 'G' suffix indicates RoHS compliant packaging. Ensure the FBGA-484 package dimensions match the design footprint. Check for current availability as older speed grades may have discontinuation notices.

Selection Notes

Select this model for designs requiring high gate density within the SX-A architecture. The -1 speed grade offers improved timing over standard versions. Consider the 484-pin package size for board space constraints. Verify that the required I/O standards are supported by the configurable I/O modules.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which were originally developed by Actel Corporation before being acquired by Microsemi and subsequently Microchip Technology. The SX-A series is characterized by its antifuse-based nonvolatile fabric and high-speed routing resources like DirectConnect and FastConnect.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing should be performed carefully as speed grades and package options vary significantly within the SX-A family.
