Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified suppliers. Confirm RoHS compliance status and humidity sensitivity handling requirements prior to assembly. Check for end-of-life notifications or discontinuance notices, as availability may be limited. Ensure proper ESD protection during storage and installation to maintain device integrity.

Selection Notes

Select this model when a 100-pin surface-mount interface is required alongside specific 5V compatibility. Compare against other MX series variants if higher gate counts or different package styles are needed. Consider the PQFP-100 footprint constraints and thermal dissipation capabilities relative to the target PCB design. Verify that the 83 available I/O pins meet the system interconnect requirements.

Part Context

This component belongs to the A42MX09 series, which provides scalable logic density for embedded applications. The MX family is known for non-volatile flash-based technology, allowing instant-on functionality without external configuration memory. This specific part represents a mid-range option within the series, balancing pin count and logic resources for complex digital designs.

Replacement Considerations

Direct substitutes include other parts within the A42MX09 series with different package options, such as A42MX09-PQG100 or A42MX09-3PQ100I, provided pin compatibility is verified. Cross-family replacements from Actel or Microsemi legacy lines may require schematic and layout modifications.
