STM32U073K8U6

STM32U073K8U6 is STMicroelectronics’ STM32U0 ultra-low-power microcontroller. It uses an ARM Cortex-M0+ core (up to about 48 MHz) with on-chip Flash and RAM and a robust peripheral set. Peripherals typically include USB Full-Speed device, UART/SPI/I2C, multiple timers and PWM, ADCs and DACs, analog comparators, and various wakeup/power-management features. It supports a broad voltage range (roughly 1.65–3.6 V) and several sleep/low-power modes for energy-efficient operation, making it suitable for battery-powered and portable applications. Package options span small to mid-size footprints to fit compact designs. Development is supported by the STM32CubeMX ecosystem, HAL/LL drivers, and STM32CubeIDE, with middleware for USB and other interfaces. Common use cases are IoT sensors, portable devices, USB peripherals, and embedded controllers requiring low power and a compact footprint. If you need exact specs (Flash/RAM sizes, pin count, package type), I can provide the datasheet details.
