Frequently asked questions
Where can I buy LM3S2651-IBZ50-A2T and how do I get a price?
The part is sourced to order against an RFQ through independent distribution channels — availability and current pricing are confirmed at quote time. The 108-LFBGA package limits which brokers carry stock, so a direct RFQ is the fastest path to a firm lead time.
What is the closest pin-compatible alternative to LM3S2651-IBZ50-A2T?
TI migrated the Stellaris family to the Tiva C Series (ARM Cortex-M4F), but pin compatibility is not direct — the 108-LFBGA pinout and peripheral mapping differ between the two series. A board respin is required; consult the TI Tiva product line for the closest functional equivalent in your target package.
