The 50 MHz Cortex-M3 core provides enough throughput for control loops and protocol stacks without external memory. The 128 KB Flash is sized for mid-complexity firmware — a Modbus TCP stack plus a PID loop fits; a full web server or large data-logging buffer would push the budget. The 32K x 8 RAM supports moderate packet buffering and stack depth for Ethernet communication.","metaTitle":"LM3S6611-EQC50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz, 128 KB Flash","metaDescription":"LM3S6611-EQC50-A2 is an obsolete Stellaris ARM Cortex-M3 MCU with 50 MHz core, 128 KB Flash, 32 KB RAM, Ethernet, industrial temp range.
