Frequently asked questions
Who supplies the LM3S5951-IQC80-C1 and how is it quoted for volume purchases?
The part is sourced to order against an RFQ through independent distribution. Availability, current pricing, and order quantity breakpoints are confirmed at quote time — no live stock or price displayed on this listing.
What is the LM3S5951-IQC80-C1 speed rating?
The listed speed is 80MHz — the ARM Cortex-M3 core runs at that clock rate from the internal oscillator.
What is the closest pin-compatible alternative to the LM3S5951-IQC80-C1?
No official cross-reference or pin-compatible alternate is listed in the available record. The Stellaris line was superseded by TI's Tiva C Series, but matching a direct functional replacement in the 100-LQFP package with the same peripheral complement and 1.08–1.32V supply range requires verification against the Tiva C pinout before specifying.
