The Texas Instruments LM3S2950-EQC50-A2T is a 32-bit ARM Cortex-M3 microcontroller from the Stellaris® Cortex®-M3S 2000 series, clocked at 50 MHz with 256 KB of Flash program memory and 64 KB of SRAM. It integrates a CANbus controller alongside I²C, SPI, SSI, UART, and IrDA interfaces, plus a quadrature encoder interface (QEI) for motor-feedback loops. 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.
Obsolete — sourcing reality
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. We source and quote it against an RFQ — availability and current pricing are confirmed at quote time. 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.
