Frequently asked questions

Is the LM3S9B92-IQC80-C5 obsolete and what does that mean for procurement?

Yes — lifecycle_stage is eol_hot. The part is no longer in standard production; it is sourced through surplus and broker channels. Any new design-in is locked out. For the installed base, assess a last-time-buy quantity against the known failure rate and end-of-life timeline on the TI PCN.

Will the 100-LQFP drop into my existing Stellaris board without rework?

The 14x14mm 100-LQFP footprint is the standard pad landing for the IQC80 variant; pin-1 orientation must match the existing board silkscreen. If the pad layout was populated for a different 100-pin variant, confirm the power and ground pin assignments before assuming drop-in fit.
