The 50 MHz core handles motor drives, industrial I/O nodes, and sensor fusion tasks. 128 KB of Flash and 32K x 8 RAM support a CANopen slave node or multi-axis stepper controller. The part includes a full set of peripherals: brown-out detect, POR, PWM, and WDT for watchdog supervision. ## Industrial temperature grade — rated for harsh environments Supply range is 2.25 V to 2.75 V. No official TI successor part number is listed for this order code. For legacy production, the surplus channel is the practical route.","metaTitle":"LM3S2601-EQC50-A2 Stellaris ARM Cortex-M3 MCU, 50MHz, 128KB Flash","metaDescription":"LM3S2601-EQC50-A2 is an obsolete 32-bit ARM Cortex-M3 MCU from TI's Stellaris series. 50MHz core, 128KB Flash, 32K x 8 RAM, -40°C to 105°C.
