Microprocessors Procurement Notes

Verify the specific ordering suffix PQA against the manufacturer's current datasheet to confirm package type, temperature range, and mass storage options. Ensure compatibility with required DDR3L or DDR4 memory configurations and validate pin assignments for the FC-PBGA 448-ball layout during hardware design.

Microprocessors Selection Notes

Select this component for designs requiring a cost-effective, power-efficient single-core solution with robust networking capabilities. It is suitable for applications needing TSN support and high-speed I/O without the complexity of multi-core architectures. Consider the 1.5 GHz performance ceiling and available SerDes lanes when evaluating bandwidth requirements.

Microprocessors Part Context

This part belongs to the NXP QorIQ Layerscape family, specifically the LS1017A series.
