A54SX72A-FGG256I

Overview

The A54SX72A-FGG256I is an industrial-grade Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It features 108,000 system gates and 6,036 logic modules within a 256-pin Fine Pitch Ball Grid Array package. The device supports up to 203 user I/Os and operates at a maximum frequency of 172 MHz. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and requires a supply voltage range of 2.25 V to 5.25 V. The component is designed for applications requiring nonvolatile configuration and deterministic timing.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements
• Supports mixed-voltage operation with 5 V input tolerance and configurable I/O standards
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing
• Includes boundary-scan testing compliance with IEEE Standard 1149.1 (JTAG)

Applications

• High-performance digital signal processing and control systems
• Industrial automation and communication interface protocols
• Secure embedded designs requiring protection against reverse engineering

Procurement Notes

Verify the specific ordering suffix 'I' confirms the Industrial temperature grade (-40°C to +85°C). Confirm the 'FGG' package designation matches the required 1.0 mm Fine Pitch Ball Grid Array footprint. Ensure compatibility with Actel Designer software for programming the antifuse structure. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this model when high gate density and deterministic performance are required in an industrial environment. The SX-A architecture offers full pin-locking capabilities, facilitating concurrent PCB development. Consider the 172 MHz speed grade for complex logic functions. Verify that the 256-pin FBGA package fits the available board space and thermal constraints.

Part Context

This component belongs to the Actel SX-A FPGA family, which provides cost-effective, low-power solutions. The SX-A series is known for its unique sea-of-modules architecture and patented antifuse technology. It serves as a bridge between CPLDs and larger FPGAs, offering immediate configuration upon power-up without external memory requirements.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX72A series, such as the standard or faster variants, provided timing requirements are met. Cross-family migration to newer Microchip ProASIC3 or PolarFire devices may require schematic and design tool adjustments.
