Procurement Notes

Verify the specific suffix D80 against official documentation to confirm the operational temperature range and package variant. Confirm RoHS compliance status through current datasheets. Check for obsolescence notices or lifecycle changes directly from Texas Instruments before finalizing procurement plans.

Selection Notes

Select this model when an 800 MHz processing speed is required alongside extensive connectivity options. Ensure the design accommodates the 324-pin BGA footprint and thermal requirements for the specified industrial temperature range. Compare against lower-frequency variants if power consumption is a critical constraint.

Part Context

This component belongs to the AM335x Sitara series, designed for cost-sensitive embedded applications. It shares architectural similarities with other members like the AM3352 and AM3354 but offers higher performance. The series targets markets demanding Linux-capable processors with rich peripheral sets.

Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify pin-to-pin compatibility and software compatibility with existing designs when considering replacements.
