The 16-channel 10-bit ADC covers analog feedback for current or temperature sensing. For a BOM engineer, the memory and I/O counts are the first gate: if your application fits in 256 KB and 64 KB, this part has the connectivity to handle most industrial communication protocols. The 108-BGA (10x10 mm) package is a surface-mount BGA with 108 balls; rework requires a hot-air station with a BGA nozzle and X-ray inspection to verify solder-joint integrity.","metaTitle":"LM3S5951-IBZ80-C1T ARM Cortex-M3 MCU, 80 MHz, 256 KB Flash","metaDescription":"LM3S5951-IBZ80-C1T Stellaris ARM Cortex-M3 MCU, 80 MHz, 256 KB Flash, 64 KB RAM, USB OTG, CAN, 108-BGA.
