At 50 MHz the Cortex-M3 handles a real-time control loop while servicing Ethernet or CAN traffic. ## Peripherals and I/O budget 31 I/O on a 100-pin package means roughly a third of the pins are dedicated to power, ground, and analog functions — typical for a mixed-signal MCU. Ethernet MAC and CAN controllers are integrated, reducing the BOM count for industrial communication nodes. ## Memory sizing It can hold a modest TCP/IP stack plus application code, but leaves limited headroom for large lookup tables or extensive data logging. Designs that need larger firmware images or bigger packet buffers will hit the ceiling — plan accordingly during architecture review.","metaTitle":"LM3S8630-IQC50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz, 128 KB Flash","metaDescription":"LM3S8630-IQC50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz, 128 KB Flash, 32 KB RAM, -40 to 85°C, 100-LQFP.
