Frequently asked questions
Where can I buy the LM3S1R26-IQR80-C5 and how do I get a price?
The LM3S1R26-IQR80-C5 is sourced to order through independent distribution against an RFQ — no live catalog stock is available. Send the order code and required quantity; availability and a quoted price are confirmed when the RFQ is processed.
What is the speed and memory rating of the LM3S1R26-IQR80-C5?
The LM3S1R26-IQR80-C5 runs at 80MHz with 256KB Flash and 48KB SRAM — the highest-flash variant in the Stellaris 1000 series at that clock rate, before stepping up to the 1000-E series or moving into the Tiva family.
