Frequently asked questions
Where can I buy LM3S2637-IBZ50-A2 and how do I get a price?
The part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no live stock or price is listed on this listing. Contact the sourcing desk to open a quote.
What is the closest pin-compatible alternative to LM3S2637-IBZ50-A2?
There is no TI-published pin-compatible successor order code on this listing. The Stellaris 2000 series has been superseded by the Tiva C Series (TM4C); a second-source path would require cross-checking pinout and peripheral compatibility with a TI TM4C equivalent or an alternative supplier's Cortex-M3 in the same package footprint.
