Product details

NRND — plan your last-time buy

If you are qualifying this part for a new BOM, you are already behind — look at the Stellaris family's active successors or a pin-compatible ARM Cortex-M3 from a current portfolio. For ongoing builds, secure your last-time-buy quantities now; the window is open but not indefinite.

25 MHz ARM Cortex-M3 with 64 KB Flash

The 41 GPIOs give you room for local sensor interfacing or relay control without an external expander.

Industrial temperature grade, BGA package

The 108-ball BGA (10x10 mm body) means reflow assembly and X-ray inspection — not a field-swap part.

Frequently asked questions

Is LM3S1110-IBZ25-A2 obsolete or still available?

That means it is still available for existing production but not recommended for new designs. Plan a last-time buy or a migration to an active successor.

What is the best replacement for LM3S1110-IBZ25-A2?

TI's Stellaris family has been superseded by the Tiva C series (TM4C123x) and later ARM Cortex-M4F parts. A direct pin-compatible drop-in is not guaranteed due to the BGA footprint change, but functionally the TM4C123GH6PM offers more Flash, RAM, and a 80 MHz Cortex-M4F core. Check the migration guide for peripheral compatibility.
