A54SX32A-FGG484M

Overview

The A54SX32A-FGG484M is a 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 (CLBs). The device supports up to 249 user-programmable I/O pins and includes dedicated flip-flops for sequential logic. It operates with internal clock frequencies up to 350 MHz and system performance up to 250 MHz. The component is housed in a 484-pin Fine Pitch Ball Grid Array (FGG) package with a 1.0 mm pitch. The 'M' suffix indicates a military temperature grade ranging from -55°C to +125°C.

Feature Summary

• Nonvolatile antifuse architecture providing permanent configuration without external memory.
• Supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V operation with 5 V input tolerance.
• Hot-swap compliant I/Os allowing insertion into active systems without power sequencing requirements.
• Integrated Boundary-Scan Testing (BST) compliant with IEEE Standard 1149.1 for diagnostic verification.

Applications

• High-performance digital signal processing and control systems requiring deterministic timing.
• Industrial and aerospace applications necessitating wide operating temperature ranges and radiation hardness.
• Complex state machine implementations and fast data path logic using DirectConnect routing resources.

Procurement Notes

Verify the specific ordering suffixes against the manufacturer's current datasheet to confirm package type, speed grade, and temperature range. Ensure that the military grade designation matches the required environmental specifications for the target application. Cross-reference the part number with official distributor catalogs to confirm availability and authenticity of the source.

Selection Notes

Select this component when a nonvolatile FPGA solution with high-speed internal routing is required. The SX-A architecture offers 100% pin-locking capabilities, which facilitates concurrent PCB layout and design. Consider the available speed grades and I/O voltage compatibility when integrating with other system components. Verify that the 484-pin FBGA package fits the physical constraints of the design.

Part Context

This device belongs to the Actel SX-A family of FPGAs, fabricated on a 0.22 μm / 0.25 μm CMOS process. The family includes devices ranging from 8,000 to 108,000 system gates. The A54SX32A variant specifically targets designs requiring moderate logic density with high performance and security features inherent to antifuse technology.

Replacement Considerations

Direct replacements within the same package and pinout are limited due to the discontinuation of many speed grades. Check for updated revisions or equivalent parts from the Microchip Technology portfolio. Verify functional compatibility if substituting with other antifuse-based FPGAs.
