Frequently asked questions
Is there a direct replacement for the LM3S2776-IQR50-A0T?
There is no TI-published pin-compatible successor at the same order code. The Stellaris line was folded into the Tiva C Series, but the memory map and peripheral configuration differ — any substitute requires a BOM revision and potentially a board respin.
Where can I source the LM3S2776-IQR50-A0T and what is the lead time?
This part is sourced to order through independent distribution against an RFQ — availability and current pricing are confirmed at quote time. Lead time and stock position vary by channel quantity and market depth.
