Frequently asked questions
What replaces the LM3S8933-IBZ50-A2T?
TI's documented migration path from Stellaris runs to the Tiva C Series (TM4Cxxx). No pin-compatible drop-in replacement exists in this ledger — any substitute will require board footprint review (the Tiva is typically QFP/TQFP, not LFBGA) and firmware porting against the Tiva register set.
What is the speed and series of this MCU?
The LM3S8933-IBZ50-A2T runs at 50MHz on an ARM Cortex-M3 core, part of the Stellaris ARM Cortex-M3S 8000 series.
