It integrates an Ethernet MAC, USB OTG, CANbus, and a 16-channel 10-bit ADC, making it a fit for networked control nodes, HMI panels, and industrial gateways that need wired connectivity without an external PHY or USB controller. The 100-LQFP package (14×14 mm) keeps the board footprint compact for a part with this peripheral set. At 80 MHz, this Cortex-M3 can execute a tight PID loop or Modbus TCP stack with headroom for a small RTOS. The 96 KB SRAM supports moderate packet buffers for Ethernet and USB traffic without external memory. For a panel retrofit or gateway design, the 80 MHz speed is enough to handle a few hundred register updates per second over Ethernet and CAN simultaneously. The 1.235 to 1.365 V core supply is tight — the board designer must keep the regulator output within that window across load and temperature.","metaTitle":"TI LM3S9B92-IQC80-C3T Stellaris ARM Cortex-M3 MCU, 80MHz","metaDescription":"Texas Instruments LM3S9B92-IQC80-C3T ARM Cortex-M3 32-bit MCU, 80MHz, 256KB Flash, 96KB SRAM, Ethernet/USB/CAN, -40 to 85°C, 100-LQFP.
