A54SX72A-1FGG484I

Overview

The A54SX72A-1FGG484I is a Field Programmable Gate Array from the Microchip SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 108,000 typical system gates and 6,036 logic modules, including dedicated flip-flops. The device supports up to 360 user-programmable I/O pins and features three global clock networks plus four quadrant clocks. It operates within an industrial temperature range of -40°C to +85°C and utilizes 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 for permanent low-impedance connections.
• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance and drive strength.
• Hot-swap compliant I/Os allowing safe insertion into electrically active systems without power sequencing requirements.
• Includes IEEE 1149.1 compliant Boundary-Scan Testing capabilities with dedicated or flexible JTAG pin configurations.

Applications

• High-performance digital signal processing requiring deterministic timing and fast counters
• Industrial control systems necessitating wide temperature operation and mixed-voltage I/O interfaces
• Communication equipment requiring hot-swappable connectivity and protocol conversion

Procurement Notes

Verify the specific speed grade suffix '1' indicates approximately 15% faster performance than standard speed. Confirm the 'I' suffix denotes the industrial temperature grade (-40°C to +85°C). Ensure the FG package type corresponds to the 1.0 mm Fine Pitch Ball Grid Array format. Check for RoHS compliance status indicated by the 'G' suffix if required for environmental regulations.

Selection Notes

Select this model when high gate density and nonvolatile configuration are required without external configuration memory. Consider the A54SX72A variant specifically for designs needing quadrant clock resources and up to 360 I/O pins. Evaluate the 0.22 μm process technology benefits for low-power applications compared to older generations. Ensure PCB design accommodates the 484-pin FBGA thermal and mechanical constraints.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which were originally developed by Actel Corporation before being acquired by Microchip Technology. The SX-A series is characterized by its antifuse-based architecture, offering high reliability and security against reverse engineering through FuseLock technology. It serves as a bridge between complex CPLDs and larger SRAM-based FPGAs in terms of capacity and performance.

Replacement Considerations

Direct replacements within the same family include other A54SX72A variants with different speed grades or packages, such as A54SX72A-2FGG484I. Cross-family migration may require architectural redesign due to differences between antifuse and SRAM technologies. Verify pin compatibility and I/O voltage levels when considering alternative devices from other manufacturers.
