Frequently asked questions
Where can I source the LM3S2678-IQR50-A0 and how is it quoted?
The LM3S2678-IQR50-A0 is sourced and quoted to order against an RFQ through independent distribution channels; availability and current pricing are confirmed at quote time. Given the NRND status, lead times and lot traceability are confirmed as part of the RFQ process rather than against live inventory.
What is the LM3S2678-IQR50-A0's clock speed and memory complement?
The LM3S2678-IQR50-A0 runs at 50MHz on an ARM Cortex-M3 core with 128KB Flash and 32KB SRAM — confirmed in the Stellaris ARM Cortex-M3S 2000 series entry.
