A54SX72A-2FGG484I

Overview

The A54SX72A-2FGG484I is a Field Programmable Gate Array from the Microchip SX-A family, featuring 108,000 system gates and 6,036 logic modules. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology for nonvolatile configuration. The device operates within an industrial temperature range of -40°C to +85°C and supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V. It is housed in a 484-pin Fine Pitch Ball Grid Array (FBGA) package with a 1.0 mm pitch.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements
• Supports hot-swap compliant I/Os allowing power-up/down without supply voltage sequencing requirements
• Includes dedicated clock resources such as HCLK, CLKA, CLKB, and quadrant clocks for deterministic timing
• Provides IEEE 1149.1 Boundary-Scan Testing compliance with flexible or dedicated JTAG pin configurations

Applications

• High-performance digital signal processing requiring fast execution of complex logic functions
• Industrial control systems necessitating robust operation across wide temperature ranges
• Hardware prototyping and design verification leveraging nonvolatile antifuse architecture
• Systems requiring secure IP protection through Actel FuseLock anti-tamper mechanisms

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm that the ordering suffix matches the required speed grade and temperature rating. Ensure compatibility with existing PCB footprints and verify that all unused pins are properly terminated according to the device manual.

Selection Notes

Select this model when designs require high gate density combined with low-power consumption and deterministic performance. Consider the specific speed grade requirements relative to standard performance levels. Evaluate the need for mixed-voltage I/O support and ensure the FBGA package fits the available board space constraints.

Part Context

This component belongs to the Actel SX-A FPGA family, which was acquired by Microchip Technology. The SX-A series is characterized by its use of antifuse technology rather than volatile SRAM-based configuration. This family provides a cost-effective platform for integrating CPLD functionality into a single chip while maintaining high-speed performance capabilities.

Replacement Considerations

Compatible alternatives within the same product line include the A54SX72A-1FGG484I for standard speed performance and the A54SX72A-FGG484I for slower speed grades. Verify that any substitute maintains the identical 484-pin FBGA footprint and meets the necessary electrical and thermal specifications.
