STMicroelectronics STM32U5 Series
STM32U5 Series - The flagship of ultra-low power MCUs with advanced performance and security
Discover the secure, high-performance, and ultra-low power STM32 microcontrollers that will revolutionize your design.
The STM32U5 microcontrollers combine the Arm® Cortex®-M33 core with power-saving features and advanced security to meet the most demanding power/ performance requirements for smart applications, including wearables, personal medical devices, home automation, and industrial sensors.
Offering up to 4 Mbytes of flash memory (dual bank) memory and 2514 Kbytes of SRAM, the STM32U5 series of microcontrollers takes performance to the next level with advanced graphics capabilities.
The STM32U5 series offers 4 different packages (LQFP, TFBGA, UFBGA and WLCSP) from 48 to 216 pins, and supports up to 125°C ambient temperature.
Enhanced security
Building on the cyber security features of the STM32L5 MCU, with its Arm Cortex-M33 core that incorporates Arm’s TrustZone® technology and an ST-specific security feature set, the STM32U5 series introduces state-of-the-art innovations:
- AES encryption and Public Key Accelerator (PKA) are now side-channel hardware- resistant
- Secure data storage with a Hardware Unique Key (HUK)
- Active tamper detection. Internal monitoring, that can erase secret data in the event of perturbation attacks, helps meet the PCI Security Standards Council (PCI SSC) requirements for Point Of Sales (POS) applications.
- PSA level 3 and SESIP (Security Evaluation Standard for IoT Platforms) level 3 certification target
Integration, size and performance
- Ensures enhanced application responsiveness:
- Arm Cortex-M33 running at 160 MHz
- New ST ART Accelerator: working both on internal and external Flash (8 Kbytes of instruction cache)
- 240 DMIPS and 651 CoreMark scores
- Up to 0.5 Mbytes of on-chip Flash offers increased cycle life, up to 100,000 read/write cycles to ensure reliable storage of user data.
- High integration and innovation: large memory with ECC on Flash and SRAM, USB Type-C w/power delivery controller, CAN FD, 14- and 12-bit ADC, Multi-function Digital Filter (MDF) and Audio Digital Filter (ADF)
