The single-cycle multiply and hardware divide keep interrupt latency predictable. ## Memory sizing: 64 KB Flash, 8 KB RAM 64 KB of Flash suits firmware images for a single control algorithm plus a modest bootloader. 8 KB of RAM handles stack, UART buffers, and ADC conversion tables. The LM3S818-EGZ50-C2 is marked with an EOL hot lifecycle stage, meaning it is approaching end-of-life or in last-time-buy status.","metaTitle":"LM3S818-EGZ50-C2 Stellaris ARM Cortex-M3 MCU, 50 MHz, 64 KB Flash","metaDescription":"LM3S818-EGZ50-C2 32-bit ARM Cortex-M3 MCU from Stellaris series. 50 MHz core, 64 KB Flash, 8 KB RAM, 6x10b ADC, -40 to 105 °C.
