The LM3S2918-IQC50-A2 is a 32-bit ARM Cortex-M3 MCU from TI's Stellaris family, clocked at 50 MHz with 256 KB of Flash and 64 KB of RAM.
It is not yet end-of-life, but TI has flagged it — so new designs should look elsewhere, and existing BOMs need a replacement plan before the last-time-buy window closes.
It is NRND (Not Recommended for New Designs), not yet fully discontinued, but TI has signaled that the part is on the path to end-of-life. Existing production can continue through the remaining supply window, but new BOMs should select a replacement.
The ARM Cortex-M3 core runs at 50 MHz — enough for real-time control and serial protocol handling, but not for heavy DSP or floating-point workloads.
