A54SX72A-FFG256

Overview

The A54SX72A-FFG256 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 domains
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements
• Includes boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG)

Applications

• High-performance digital signal processing requiring deterministic timing
• Industrial control systems necessitating hot-swappable interface capabilities
• Secure embedded applications utilizing FuseLock technology to prevent reverse engineering

Procurement Notes

Verify the specific speed grade suffix associated with the FFG256 package, as standard speed variants exist alongside faster options. Confirm that the industrial temperature grade (-40°C to +85°C) aligns with environmental requirements. Ensure design tools support the SX-A architecture for proper place-and-route implementation.

Selection Notes

Select this component when high gate density and low-power consumption are required in a nonvolatile FPGA format. Consider the A54SX72A for designs needing extensive global clocking resources, including quadrant clocks unique to this capacity level. Evaluate the 256-pin FBGA package constraints against PCB layout capabilities due to fine pitch dimensions.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which transitioned to Microchip Technology following acquisition. The SX-A series is characterized by its use of antifuse programming technology, offering permanent configuration without external memory. This family targets applications demanding high reliability and security in aerospace, defense, and industrial sectors.

Replacement Considerations

Direct pin-compatible replacements within the same package and speed grade should be sourced from the A54SX72A product line. Verify functional equivalence regarding I/O counts and logic resources when considering alternative speed grades or temperature variants.
