The part is rated for industrial temperature range (-40 to 85 °C) and comes in a 108-ball BGA (10x10 mm). This was a mid-range Stellaris part for control and connectivity applications in factory automation, building control, and sensor hubs. There is no official L* successor listed in the evidence. For new designs, look at the current TI Cortex-M4 or M33 portfolio; for existing BOMs, secure last-time-buy quantities or plan a pin-compatible migration.","metaTitle":"LM3S1911-IBZ50-A2 Stellaris ARM Cortex-M3 MCU, 50MHz, 256KB Flash","metaDescription":"LM3S1911-IBZ50-A2 Stellaris ARM Cortex-M3 MCU, 50MHz, 256KB Flash, 64KB SRAM, 60 GPIO, -40 to 85°C, 108-BGA.
