Peripherals include USB OTG, CAN, I²C, SPI, SSI, UART, LIN, IrDA, 16-channel 10-bit ADC, PWM, and QEI. ## EOL — last-time-buy window closed This part is obsolete. The last-time-buy window has passed; production ceased. Any available units are from surplus or broker channels. The 80 MHz core on this Stellaris MCU handles real-time control loops and protocol stacks without external memory. The 128 KB Flash is enough for moderate firmware loads; the 32K x 8 SRAM supports a modest RTOS heap and data buffers. The USB OTG peripheral adds host/device flexibility for field-update or data-logging applications.","metaTitle":"LM3S5651-IBZ80-C3 Stellaris ARM Cortex-M3 MCU, 80 MHz, 128 KB Flash, 108-BGA","metaDescription":"LM3S5651-IBZ80-C3 is an obsolete Stellaris ARM Cortex-M3 MCU with 80 MHz core, 128 KB Flash, 32K x 8 RAM, and USB OTG.
