The 80 MHz clock rate sets the timing budget for control loops running at tens of kilohertz and for protocol stacks like TCP/IP or CANopen without external PHY bottlenecks. 128 KB Flash is enough for moderate-complexity firmware — a bootloader, a real-time kernel, and a few protocol stacks — but not for a full embedded Linux or heavy GUI. The 64 KB RAM supports moderate data buffering; designs needing larger packet buffers or multiple frame stores should budget for external SRAM via the EBI/EMI interface. Housed in a 100-LQFP (14x14 mm) surface-mount package, with 65 general-purpose I/O.","metaTitle":"LM3S9792-IQC80-C5 Stellaris ARM Cortex-M3 MCU, 80 MHz","metaDescription":"LM3S9792-IQC80-C5 32-bit ARM Cortex-M3 MCU from TI's Stellaris series. 80 MHz core, 128 KB Flash, 64 KB RAM, CAN/Ethernet/USB OTG, -40°C to 85°C.
