The 96 KB SRAM leaves room for Ethernet frame buffers and a modest RTOS heap. If your application needs to service CAN, USB, and Ethernet concurrently, budget the interrupt latency — the nested vectored interrupt controller (NVIC) handles preemption cleanly, but heavy DMA use (the part includes a DMA controller) reduces CPU load for data movement. ## Industrial temperature range and 108-ball BGA footprint Supply voltage is a tight 1.235 V to 1.365 V core rail, so a clean 1.3 V LDO is needed; the I/O bank runs separately (3.3 V typical, though the evidence does not specify the I/O supply range explicitly).","metaTitle":"LM3S9DN6-IBZ80-A2 Stellaris ARM Cortex-M3 MCU, 80 MHz","metaDescription":"LM3S9DN6-IBZ80-A2 Stellaris ARM Cortex-M3 MCU with 80 MHz core, 512 KB Flash, 96 KB SRAM, Ethernet, USB OTG, CAN.
