It runs at 50 MHz, carries 128 KB of Flash program memory and 32 KB of RAM, and integrates an Ethernet MAC alongside I²C, SPI, SSI, UART/USART, IrDA, and Microwire serial interfaces. The 46 GPIO lines and on-chip peripherals — brown-out detect, POR, PWM, watchdog timer — suit it for industrial gateways, remote I/O nodes, and HMI panels where the -40°C to 85°C industrial temperature grade is required. The 50 MHz clock rate on the ARM Cortex-M3 core delivers 50 MHz. The 32 KB RAM provides working space for packet buffers and protocol state tables. ## Ethernet MAC — wired connectivity built in","metaTitle":"LM3S6611-IQC50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S6611-IQC50-A2T 32-bit ARM Cortex-M3 MCU from the Stellaris 6000 series. 50 MHz core, 128 KB Flash, 32 KB RAM, Ethernet MAC, industrial temp range.
