Frequently asked questions
What replaces the LM3S2601-IBZ50-A2?
No official successor or cross-reference order code is listed in this ledger. Engineers looking for a replacement will need to reference TI's product change notifications and the broader Tiva C series portfolio for a functionally equivalent ARM Cortex-M3 option at updated production status.
Where can I source the LM3S2601-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 — submit a request and the supply desk will come back with a firm quote and lead time based on current independent channel reach.
What supply voltage does the LM3S2601-IBZ50-A2 require?
The part operates on a 2.25V to 2.75V rail, a 2.5V nominal design — notably narrower than the common 3.3V MCU rail, which requires a dedicated regulator stage on boards that run other logic at 3.3V.
How many I/O pins does the LM3S2601-IBZ50-A2 have?
The part provides 60 general-purpose I/O pins in a 108-lead LFBGA package.
