A54SX32A-FG256I

Overview

The A54SX32A-FG256I is an industrial-grade Field Programmable Gate Array from the Microchip Actel SX-A family, featuring 48,000 system gates and a 1.0 mm Fine Pitch Ball Grid Array package with 256 pins. It supports up to 203 user I/Os and operates within a voltage range of 2.25 V to 2.75 V. The device functions reliably across an extended temperature range of -40°C to +85°C.

Feature Summary

• Supports mixed-voltage operation for 2.5 V, 3.3 V, and 5 V I/Os with 5 V input tolerance.
• Features hot-swap compliant I/Os that allow safe insertion into active systems without power sequencing.
• Includes IEEE 1149.1 Boundary-Scan Testing capabilities for diagnostic verification.

Applications

• Industrial control systems requiring deterministic timing and robust I/O standards.
• Automotive electronics operating under strict environmental conditions.
• Military applications utilizing high-reliability programmable logic solutions.

Procurement Notes

Verify the specific suffix 'I' confirms the Industrial temperature grade (-40°C to +85°C). Confirm the FG256 designation matches the required 1.0 mm FBGA footprint. Ensure compliance with RoHS packaging requirements if applicable to the manufacturing process.

Selection Notes

Select this model when 48,000 system gates are sufficient for the design logic. Choose the FG256 package for high-density surface-mount assembly needs. Verify that the 203 available I/O pins meet the interface requirements for the target application.

Part Context

This component belongs to the Actel SX-A series, which utilizes antifuse technology for nonvolatile configuration. The SX-A architecture provides high performance through metal-to-metal interconnects and dedicated routing resources like DirectConnect and FastConnect.

Replacement Considerations

Check for other speed grades within the A54SX32A series or alternative packages in the same family. Consult official discontinuation notices for end-of-life status before selecting substitutes.
