At 80 MHz, the Cortex-M3 executes a single-cycle multiply and hardware divide, which matters for real-time control loops and protocol parsing. The Ethernet MAC and USB OTG controller can saturate the bus if the DMA engine isn't configured right — the part includes DMA, so offloading packet movement from the core is the right approach for maintaining throughput on both interfaces simultaneously. ## Connectivity set for a gateway role This MCU carries CAN, Ethernet, and USB OTG on the same die — a combination that made it a natural fit for building-automation controllers and industrial protocol gateways. The EBI/EMI interface also allows glueless connection to external SRAM or Flash, useful when the 96 KB of on-chip RAM isn't enough for large packet buffers or data logs.","metaTitle":"LM3S9B96-IBZ80-C3T Stellaris ARM Cortex-M3 MCU, 80 MHz, 256 KB Flash","metaDescription":"Obsolete LM3S9B96-IBZ80-C3T from TI's Stellaris ARM Cortex-M3S 9000 series. 80 MHz, 256 KB Flash, 96 KB RAM, CAN/Ethernet/USB OTG, 108-BGA.

For a pin-compatible alternative within the Stellaris family, verify the specific package and peripheral set against other LM3S9B96 variants — the base product number LM3S9B96 shares the same die and BGA footprint, but speed and temperature grades differ by suffix. A full BOM re-evaluation with a current-generation Cortex-M4 or M7 part is the practical path for new designs."},{"question":"What are the main specifications of LM3S9B96-IBZ80-C3T?","answer":"The LM3S9B96-IBZ80-C3T is a 32-bit ARM Cortex-M3 MCU running at 80 MHz, with 256 KB Flash, 96 KB RAM, CAN, Ethernet, USB OTG, and 65 GPIOs in a 108-BGA package.
