Frequently asked questions
Where can I buy the LM3S2776-IQR50-A0 and what is the lead time?
The part is sourced and quoted to order through independent distribution against an RFQ; availability and current pricing are confirmed at quote time. Lead time varies by channel and lot date code — request a quote to get a specific schedule for your order quantity.
What supply voltage does the LM3S2776-IQR50-A0 require?
The LM3S2776-IQR50-A0 operates on 2.25V to 2.75V, which is narrower and lower than a standard 3.3V industrial rail — a dedicated 2.5V regulator or LDO is typically required on the board.
What replaces the LM3S2776-IQR50-A0 if I need a new-design alternative?
TI's Stellaris line was succeeded by the Tiva C series; the Stellaris base product number LM3S2776 is the entry point for cross-referencing compatible variants. Confirm the recommended replacement with a TI field representative for your specific voltage and peripheral requirements.
