            STM32U3 Ultra-Low-Power Embedded Microcontrollers
                    STMicroelectronics ultra-low-power devices can extend battery life in activity-tracking applications
    

Image of STMicroelectronics STM32U3 Ultra-Low-Power Embedded Microcontrollers Built on innovative subthreshold technology, the STMicroelectronics STM32U3x family of ultra-low-power devices can extend battery life in activity-tracking applications by up to seven times compared with the previous generation. Powered by an Arm® Cortex®-M33 and offering expanded memory options (up to 2 MB of Flash and 640 KB of SRAM), the STM32U3 series supports both standard and extended industrial temperature ranges (-40°C to +85°C and up to +105°C), making it well-suited for demanding industrial environments. The STM32U3B/C5x variants also integrate advanced cryptographic capabilities.
