STM32U5 is the first STM32 to receive SESIP and PSA level 3 certification.Built-in, certified security features take cyber protection to a new level and streamline your IoT design process.
The new MCUs extend the memory range from 128Kbyte Flash and 274KB of SRAM for cost-sensitive applications, while also adding high-density versions for complex applications and sophisticated smartphone-like user interfaces. Among these, the STM32U59x/5Ax with 4Mbyte Flash and 2.5Mbyte SRAM has the largest on-chip memory of any STM32 MCU to date.The STM32U5 series also breaks the constraints on graphics performance that typically apply to ultra-low-power MCUs. Variants with ST’s advanced NeoChrom graphics processing unit (GPU) on-chip can run a sophisticated graphical user interface (GUI), previously only possible with an expensive microprocessor-based system. A tiny, embedded processor can now host smartphone-like user experiences and GUI development can leverage ST’s TouchGFX framework that now features SVG support and rich graphical assets.
Also, unlike the processors typically needed to support such sophisticated capabilities, STM32U5 MCUs come in an economical LQFP100 package that permits a simplified PCB construction with minimal layer count.
