STM32U5 Series of Ultra-Low-Power MCUs

STMicroelectronics STM32U5 Series of Ultra-Low-Power MCUs are advanced power-saving microcontrollers based on the Arm® Cortex®-M33. The devices meet the most demanding power/performance requirements for smart applications. These applications include wearables, personal medical devices, home automation, and industrial sensors. The STM32U5 series of microcontrollers takes performance to the next level with up to 2Mbytes of Flash (dual bank) memory and 786Kbytes of SRAM. The STM32U5 is a large portfolio with 8 packages (from 48 to 169 pins) and supports up to 125°C ambient temperature.
