A54SX72A-FFGG256

Overview

The A54SX72A-FFGG256 is a Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It features 108,000 system gates and 6,036 configurable logic blocks (CLBs). The device supports up to 203 user I/Os and includes 4,024 dedicated flip-flops. It operates within a supply voltage range of 2.25 V to 5.25 V and functions at temperatures between -40°C and +85°C. Packaged in a 256-pin Fine Pitch Ball Grid Array (FBGA), it utilizes antifuse technology for nonvolatile configuration.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements
• Supports mixed-voltage operation with 5 V input tolerance and drive strength across 2.5 V, 3.3 V, and 5 V supplies
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements
• Includes boundary-scan testing compliance with IEEE Standard 1149.1 (JTAG) for diagnostic verification

Applications

• High-performance digital signal processing requiring deterministic timing
• Industrial control systems necessitating hot-swappable interface capabilities
• Secure embedded applications utilizing FuseLock anti-tamper protection
• Complex state machine implementations leveraging fast local routing resources

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified agents. Confirm that the specific ordering suffix matches the required speed grade and temperature range. Ensure proper handling procedures are followed due to moisture sensitivity classification. Review the latest datasheet revisions for any updates regarding pin assignments or electrical characteristics prior to final procurement decisions.

Selection Notes

Select this model when high gate density and robust I/O flexibility are required for complex logic designs. Consider the antifuse architecture for permanent configuration needs where reprogramming is unnecessary. Evaluate the specific speed grade requirements against the standard performance metrics. Ensure the 256-pin FBGA package fits the available PCB real estate and thermal constraints of the target application environment.

Part Context

This component belongs to the Actel SX-A FPGA family, which was originally developed by Actel Corporation before being acquired by Microchip Technology. The SX-A series is characterized by its use of antifuse technology rather than SRAM-based configuration, providing inherent security and nonvolatile storage. This specific part represents one of the higher-density devices within the commercial and industrial temperature grade offerings of that generation.

Replacement Considerations

Direct replacements may include other A54SX72A variants with different speed grades or packages, such as A54SX72A-FG256I. Verify compatibility with existing design tools and ensure that any substitute maintains the same pinout and electrical specifications. Cross-reference with current Microchip product portfolios for potential next-generation alternatives if long-term availability is a concern.
