At 80 MHz the Cortex-M3 delivers 80 MHz core speed. The 64K x 8 SRAM buffers USB descriptors and CAN message objects. ## Obsolete — sourcing reality for this BOM line ## Integration note — 108-BGA on a 10x10 mm grid The 108-ball BGA (10x10 mm) requires a four-layer PCB for fanout. Core supply is 1.08 V to 1.32 V; I/O rail is separate.","metaTitle":"LM3S5791-IBZ80-C1T Stellaris ARM Cortex-M3 MCU, 80 MHz","metaDescription":"LM3S5791-IBZ80-C1T Stellaris ARM Cortex-M3 MCU, 80 MHz, 128 KB Flash, 64K x 8 SRAM, industrial temp -40°C to 85°C, 108-BGA.
