Frequently asked questions
What is the closest pin-compatible alternative to the LM3S5K31-IQC80-C0?
No official L* successor or cross-reference order code appears in the available record for this specific variant. The search should be conducted within the broader LM3S5Kxx base product family or against TI's Tiva C equivalent ARM Cortex-M3 MCUs — both share register-compatible peripheral sets that reduce migration effort compared to a clean-sheet replacement.
Where can I buy the LM3S5K31-IQC80-C0 and what are current lead times?
The LM3S5K31-IQC80-C0 is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no live inventory count or firm lead-time figure is published, as the part moves through the surplus and broker channel.
