The LM3S2918-IBZ50-A2: The LM3S2918 is a 32-bit ARM Cortex-M3 microcontroller from the Stellaris 2000 series.
If your application needs more headroom, the Stellaris family scales to higher densities — but this part's 50 MHz and memory pairing is the sweet spot for a medium-complexity motor drive or remote I/O node.
If your assembly line is set up for QFP rather than BGA, factor in the process change.
The ARM Cortex-M3 core runs at 50 MHz.
