For control loops that need deterministic response, the 80 MHz clock keeps interrupt latency under a microsecond. If your algorithm fits in 256 KB of Flash and you are not doing heavy DSP, this core is a solid fit. ## Connectivity for industrial and automotive gateways That makes it a natural choice for a CAN-to-USB gateway or a multi-protocol bridge between a factory floor and a PC. The 67 GPIOs give you enough headroom to interface to a small keypad, a character LCD, and a handful of sensors without an external port expander. ## Lifecycle reality — obsolete, sourced to order ## Package and environment 108-ball LFBGA (10x10 mm body), surface-mount. Operating temperature -40°C to 85°C. Supply voltage 1.08 V to 1.32 V.","metaTitle":"LM3S5951-IBZ80-C3 Stellaris ARM Cortex-M3 MCU, 80 MHz, 256 KB Flash, Obsolete","metaDescription":"LM3S5951-IBZ80-C3 is an obsolete Stellaris ARM Cortex-M3 MCU with 80 MHz core, 256 KB Flash, 64K x 8 RAM, CANbus & USB OTG.
