The part operates from 2.25 V to 2.75 V and is rated for -40 °C to 105 °C, making it suitable for industrial control, motor drive, and automotive-adjacent applications where extended temperature and CAN connectivity are required. Texas Instruments has marked the LM3S2950-EQC50-A2T as obsolete. No official successor is listed in the Stellaris family; the Stellaris line was wound down by TI several years ago. This part is available only through the surplus and broker channel. The 100-LQFP package and 2.25-2.75 V supply make it a drop-in for existing BOMs, but new designs should consider active Cortex-M3 or M4 alternatives from TI or other vendors.","metaTitle":"TI LM3S2950-EQC50-A2T ARM Cortex-M3 MCU, 50 MHz, 256 KB Flash","metaDescription":"Texas Instruments Stellaris LM3S2950-EQC50-A2T 32-bit ARM Cortex-M3 MCU, 50 MHz, 256 KB Flash, 64 KB SRAM, CANbus/I²C/SPI/UART, -40 to 105°C, 100-LQFP.
