Frequently asked questions
Where can I buy the LM3S1Z16-IQR50-C3 and what is the lead time?
The part is quoted to order through independent distribution channels. Availability and current lead times are confirmed against an RFQ before a BOM commitment — it is not available for immediate shipment from forward stock.
What is the LM3S1Z16-IQR50-C3's clock speed?
The LM3S1Z16-IQR50-C3 runs at 50MHz, driven by an internal oscillator — no external crystal required for the core clock.
What series does the LM3S1Z16-IQR50-C3 belong to?
It is a member of the Stellaris ARM Cortex-M3S 1000 series, TI's 32-bit MCU family that preceded the Tiva rebrand.
