It has 512 KB of Flash and 96 KB of RAM, with Ethernet, USB OTG, CAN, and multiple serial interfaces. 80 MHz on a Cortex-M3 provides 80 MIPS of single-cycle throughput. This supports a Modbus TCP stack alongside a PID loop at a few kilohertz. ## 512 KB Flash and 96 KB RAM — sizing the firmware 512 KB of program Flash is generous for a mid-range MCU — it holds a full TCP/IP stack, a USB device stack, and application code without external memory. The 96 KB SRAM handles packet buffers and runtime data; if your application uses Ethernet jumbo frames or large lookup tables, watch the RAM budget.","metaTitle":"LM3S9DN5-IQC80-A2 Stellaris ARM Cortex-M3 MCU, 80 MHz","metaDescription":"LM3S9DN5-IQC80-A2 Stellaris ARM Cortex-M3S 9000 MCU, 80 MHz, 512 KB Flash, 96 KB RAM, Ethernet/USB OTG/CAN, -40 to 85°C.
