The integrated Ethernet MAC handles the frame-level work; the CPU stays free for application logic and the dual CAN controllers manage bus arbitration. For a design that previously needed a separate Ethernet controller or a second MCU for the CAN gateway, this part collapses the BOM.","metaTitle":"TI LM3S9L97-IBZ80-C5 Stellaris ARM Cortex-M3 MCU, 80 MHz","metaDescription":"Texas Instruments LM3S9L97-IBZ80-C5 Stellaris ARM Cortex-M3 MCU, 80 MHz, 128KB Flash, 48KB RAM, Ethernet, dual CAN, USB OTG.
