It carries 32 KB of Flash program memory and 8K x 8 of SRAM, with 34 GPIOs, a 2-channel 10-bit ADC, and serial interfaces covering I²C, Microwire, SPI, SSI, and UART/USART. The 50 MHz core speed on this Stellaris part is enough for a single motor-control PWM loop or a Modbus RTU master with a few analog inputs. It is not a high-throughput part — the 8K x 8 SRAM limits buffering for Ethernet or heavy data logging. For a simple drive controller or a sensor hub handling one or two UART streams, the 50 MHz Cortex-M3 with its integrated PWM and watchdog peripherals is a clean fit.","metaTitle":"Texas Instruments LM3S615-EQN50-C2T Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"Obsolete TI Stellaris LM3S615-EQN50-C2T 32-bit ARM Cortex-M3 MCU, 50 MHz, 32 KB Flash, 8K x 8 RAM, -40°C to 105°C.
