The LM3S2911-IBZ50-A2T is a 32-bit ARM Cortex-M3 MCU from TI's Stellaris 2000 series, clocked at 50 MHz with 256 KB of Flash and 64 KB of RAM. That memory split handles a moderate firmware image — think motor-control loops with CANopen stack, or a multi-protocol gateway translating between CAN and serial — without external memory.
NRND — plan the next spin now
Factory support is winding down; future LTB windows are likely. For existing production, secure a last-time-buy buffer or validate a drop-in replacement before the next BOM freeze.
Industrial temperature range and BGA footprint
The 108-ball BGA (10x10 mm) requires a controlled reflow profile.
