Frequently asked questions
Where can I buy the LM3S2139-EQC25-A2T and what is the lead time?
This part is sourced to order through independent distribution; availability and current pricing are confirmed when you request a quote. No authorised-stock position is available — the procurement step is an RFQ, not a direct online purchase.
What is the supply voltage range of the LM3S2139-EQC25-A2T?
The device operates from 2.25 V to 2.75 V — a narrower band than the standard 3.3 V rail, so verify your board's power architecture before committing this to a BOM line.
Does the LM3S2139-EQC25-A2T have a pin-compatible second source or successor?
No official TI cross-reference or second-source alternate is cited in this listing's ledger. Any alternate part will need a cross-functional review against the 100-LQFP pinout, 56 I/O allocation, and the 2.25–2.75 V supply window.
