Interfaces include CAN, Ethernet, USB OTG, UART, SPI, I²C, and 16-channel 12-bit ADC. ## 80 MHz and the connectivity stack At 80 MHz the Cortex-M3 has enough headroom to run a lightweight TCP/IP stack (lwIP or similar) alongside a CANopen master and a Modbus RTU slave on the UARTs. The 96 KB SRAM is the tight spot — if you're buffering large Ethernet frames or running a USB host stack, budget that RAM early. The 512 KB Flash holds a full firmware image with room for a bootloader and a small file system.","metaTitle":"LM3S9D92-IBZ80-A2 Stellaris ARM Cortex-M3 MCU, 80 MHz, 512 KB Flash","metaDescription":"LM3S9D92-IBZ80-A2 Stellaris ARM Cortex-M3S 9000 MCU, 80 MHz, 512 KB Flash, 96 KB RAM, CAN/Ethernet/USB OTG.
