It operates from 3 V to 3.6 V and includes a 4-channel 10-bit ADC, PWM, and brown-out detect/reset. ## 50 MHz core and on-chip peripherals — BOM-fit considerations The 50 MHz Cortex-M3 core with 32 KB Flash and 8 KB RAM places this MCU in the value-tier of the Stellaris line. For a design that needs a simple control loop with a handful of serial interfaces and one ADC channel, the LM3S611 delivers without over-provisioning. Brown-out detection and POR are integrated, reducing the need for an external supervisor IC. ## Where the 105°C rating matters The 105°C ceiling allows the MCU to sit next to a switching regulator or a hot power MOSFET without forced airflow, as long as the junction temperature stays under the rated limit. The 48-LQFP package with a 7x7 mm footprint is a common layout for space-constrained industrial PCBs.","metaTitle":"Texas Instruments LM3S611-EQN50-C2 Stellaris ARM Cortex-M3 MCU, 50MHz","metaDescription":"Obsolete TI LM3S611-EQN50-C2 32-bit ARM Cortex-M3 MCU, 50MHz, 32KB Flash, 8KB RAM, -40°C to 105°C, 48-LQFP.
