The 60 general-purpose I/O pins give headroom for parallel displays, keypads, or custom logic interfaces without external GPIO expanders. Texas Instruments lists this part as NRND (Not Recommended for New Designs). Existing production runs and maintenance spares are still viable, but new projects should evaluate the current-generation Stellaris or Tiva-C family for pin-compatible or functionally equivalent migration. The 108-BGA (10x10 mm) package and 2.25-2.75 V supply rail are specific to this variant — any replacement must match the footprint and voltage domain to avoid a board spin. ## Industrial temperature and board integration The internal oscillator eliminates the external crystal in many applications, though the 50 MHz core clock can also be driven from an external source for tighter timing accuracy.","metaTitle":"LM3S2950-IBZ50-A2T Texas Instruments ARM Cortex-M3 MCU","metaDescription":"Texas Instruments LM3S2950-IBZ50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz, 256 KB flash, 64 KB RAM, 108-BGA.
