Product details

For a buyer filling a BOM line, this means the part can be sourced through independent distribution on a quoted-to-order basis, but the window for last-time-buy or transition planning is open.

Memory and peripheral fit for control applications

The 49 I/O pins in a 100-pin LQFP give headroom for parallel LCD interfaces, keypad matrices, and multiple encoder inputs without a port expander. The 3-channel 10-bit ADC is adequate for reading potentiometers, current shunts, or NTC thermistors at sample rates under 200 ksps — not for high-speed data acquisition, but fine for supervisory monitoring in a motor drive or HVAC controller.

Frequently asked questions

Is LM3S2412-IQC25-A2T obsolete?

It remains available for existing production through independent distribution, but Texas Instruments has flagged it for end-of-life transition. Sourcing is confirmed on a quoted-to-order basis against an RFQ.

What is the replacement for LM3S2412-IQC25-A2T?

For a new design, the recommended path is to evaluate a current-production Stellaris or TM4C series ARM Cortex-M4 part from TI with compatible peripheral set and pin count. The NRND status means the original part can still be sourced for legacy BOM lines through independent channels.
