ST STM32U5
The ST STM32U5 series are 32-bit ultra low power microcontrollers based on the ARM Cortex-M33 processor.
Device family
The STM32U5 device family consists of several subfamilies: STM32U57xxx, STM32U58xxx, STM32U59xxx and STM32U5Axxx.

On-Chip Memory Regions
The internal flash consists of up to 4MiB of memory.
Device | Flash size (MiB) | Start address | End address |
---|---|---|---|
STM32U5xxxG | 1 | 0x08000000 | 0x080FFFFF |
STM32U5xxxI | 2 | 0x08000000 | 0x081FFFFF |
STM32U5xxxJ | 4 | 0x08000000 | 0x083FFFFF |
Reset
No special reset is required.
Example Application
The following example project was created with the SEGGER Embedded Studio project wizard and should run out-of-the-box on any ST STM32U5xxxx device. It is a simple for loop incrementing the integer i. The application is linked into the internal flash.
