It integrates USB OTG, CAN, and multiple serial interfaces (SPI, SSI, UART, IrDA, Microwire). The 50 MHz Cortex-M3 core delivers enough throughput for real-time control loops (motor commutation, sensor fusion) and protocol handling (USB OTG, CAN) without an external PHY for most cases. 33 GPIOs, a 4-channel 10-bit ADC, internal oscillator, and peripherals including brown-out detect, DMA, POR, PWM, and WDT. The USB OTG interface supports device and host modes.","metaTitle":"LM3S5662-IQR50-A0 Stellaris ARM Cortex-M3 MCU, 50 MHz, 128 KB Flash","metaDescription":"LM3S5662-IQR50-A0 32-bit ARM Cortex-M3 MCU, 50 MHz, 128 KB Flash, 32 KB RAM, USB OTG, CAN, -40°C to 85°C.
