It carries an integrated Ethernet MAC+PHY alongside I²C, SPI, SSI, UART, IrDA, LIN, and Microwire — a connectivity set that fits industrial gateways, HMI panels, and motor-drive control boards where one chip handles both fieldbus and TCP/IP traffic. The 100-LQFP package (14x14 mm) routes 46 GPIOs, enough for parallel LCD interfaces or encoder feedback capture without an external port expander. Rated for -40°C to 85°C ambient, this MCU runs on a 3V to 3.6V supply rail. ## Peripherals and DMA for real-time throughput DMA engine and PWM timers with dead-band insertion make this part suitable for dual-motor control loops where the CPU handles comms and the DMA shuttles ADC results to RAM. The 64 KB RAM is enough to buffer a few Ethernet packets or a Modbus TCP transaction without stalling the core. Brown-out detect and watchdog timer add the safety net expected in a machine-control environment.","metaTitle":"LM3S6C11-IQC80-A2T Stellaris ARM Cortex-M3 MCU, 80MHz","metaDescription":"LM3S6C11-IQC80-A2T Stellaris ARM Cortex-M3 MCU, 80MHz, 512KB Flash, 64KB RAM, Ethernet, -40°C to 85°C.
