The 80 MHz Cortex-M3 core delivers enough throughput to run a full TCP/IP stack (lwIP or similar) alongside a CANopen or Modbus RTU application without a dedicated protocol offload engine. The 512 KB Flash holds that stack plus a bootloader and application image; the 96 KB RAM leaves headroom for packet buffers and real-time data arrays. If your design needs to bridge an Ethernet fieldbus to a CAN-based drive network, this part handles both PHY interfaces on-chip. Texas Instruments has marked this part as obsolete. For legacy BOM lines requiring this exact MCU, sourcing is through surplus or independent distribution. ## Connectivity and I/O count","metaTitle":"Texas Instruments LM3S9DN6-IQC80-A2 ARM Cortex-M3 MCU, 80 MHz","metaDescription":"TI Stellaris LM3S9DN6-IQC80-A2: 32-bit ARM Cortex-M3 MCU, 80 MHz, 512 KB Flash, 96 KB RAM, Ethernet MAC, CAN, USB OTG, 100-LQFP, -40°C to 85°C.
