Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified suppliers. Confirm RoHS compliance status and check for Product Change Notifications (PCNs) regarding assembly site changes. Ensure proper handling procedures are followed due to moisture sensitivity classification. Validate that the specific suffix matches the required voltage and temperature specifications.

Selection Notes

Select this model when 36,000 system gates and 125 I/O pins are required for complex logic designs. Choose the PQFP-160 package for surface-mount compatibility. Verify that the -1 speed grade meets the target clock frequency requirements. Consider the mixed-voltage I/O options if interfacing with both 3.3V and 5V peripherals.

Part Context

This part belongs to the A42MX24 series within the broader MX FPGA portfolio. It shares architectural similarities with other variants like the A42MX24-2PQG160I but differs in speed grade and operating temperature range. The series is characterized by its non-volatile flash-based technology and robust automotive-grade reliability standards.

Replacement Considerations

Direct replacements include other speed grades within the A42MX24 series, such as the A42MX24-2PQG160I or A42MX24-3PQG160, provided timing constraints allow. Cross-family migration to newer Microchip PolarFire or Igloo devices may be necessary for long-term supply assurance, requiring design re-verification.
