It targets industrial control, building automation, and networked embedded systems where on-chip Ethernet, CAN, and USB OTG eliminate the need for external interface chips. The 108-ball BGA package (10x10 mm) keeps the board footprint compact for space-constrained designs. ## Lifecycle status: obsolete — sourcing reality for the BOM line The internal oscillator eliminates the crystal for UART and I²C timing, saving two BOM lines, though Ethernet and CAN still require an external clock source for precision.","metaTitle":"LM3S9792-IBZ80-C1 Stellaris ARM Cortex-M3 MCU, 80MHz, 128KB Flash","metaDescription":"LM3S9792-IBZ80-C1 Stellaris ARM Cortex-M3 MCU. 80MHz, 128KB Flash, 64KB SRAM.
