Procurement Notes

Verify component authenticity through authorized Microchip distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Review official Product Change Notifications for any recent manufacturing updates. Ensure packaging integrity matches standard tray specifications for surface-mount processing.

Selection Notes

Select this model when 36K system gate capacity and 150 I/Os are required in a 176-pin form factor. Consider the FTQG176 suffix for specific temperature and package variations within the MX series. Evaluate mixed-voltage requirements against available 3.3V or 5.0V I/O options. Compare against other MX devices if different gate counts or pin configurations better suit the design constraints.

Part Context

This component belongs to the Microchip MX FPGA family, originally developed by Actel before acquisition. The series is known for anti-fuse technology providing non-volatile configuration without external memory. The A42MX24 variant represents a mid-range density option within the broader MX portfolio, balancing performance and pin count for complex logic implementations.

Replacement Considerations

Publicly confirmed substitute part numbers for the A42MX24-FTQG176 were not identified in verified documentation. Designers should consult Microchip engineering support for qualified cross-references or migration paths within the current MX product line.
