The 100-LQFP package exposes 67 GPIOs and a 16-channel 10-bit ADC, rated for -40 to 85 °C. At 80 MHz the Cortex-M3 executes a single-cycle multiply and a hardware divide, so a PID loop or a Modbus packet handler finishes in deterministic time. ## Connectivity and I/O — industrial gateway fit USB OTG plus CAN and a full set of UART/SPI/I²C ports make this MCU a natural fit for an industrial gateway or an HMI controller that talks to both a fieldbus and a host PC. The 67 GPIOs in a 100-pin LQFP give enough headroom for a parallel LCD interface or a keypad matrix without an external port expander.","metaTitle":"LM3S5651-IQC80-C0 Stellaris ARM Cortex-M3 MCU, 80 MHz, 128 KB Flash","metaDescription":"LM3S5651-IQC80-C0 is an obsolete Stellaris ARM Cortex-M3 MCU with 80 MHz speed, 128 KB Flash, 32 KB RAM, USB OTG, and CAN.
