Overview

The STM32U585RIT6 is an ultra-low-power 32-bit microcontroller based on the Arm Cortex-M33 core with TrustZone and FPU, operating at up to 160MHz. It integrates 2MB of Flash and 786KB of RAM, featuring advanced hardware accelerators like the Chrom-ART Accelerator and FMAC for efficient processing. This MCU is designed for demanding IoT and industrial applications that require high security and minimal power consumption, utilizing an embedded SMPS and LDO for flexible power management.

Why Choose This Part

It offers exceptional efficiency through its 160MHz Cortex-M33 core and dedicated hardware accelerators which reduce CPU load and power draw. The inclusion of TrustZone and specialized security features provides a hardware-isolated environment for secure boot and key storage. Additionally, the massive 786KB SRAM and 2MB Flash allow for complex software stacks and local data buffering without external memory.

Applications

Secure IoT Nodes
Leverages TrustZone, active tampers, and hardware cryptographic features to protect sensitive data in connected devices.
Battery-Powered Wearables
Utilizes ultra-low-power modes like Stop 2 (8.95uA) and a 19.5uA/MHz run mode to extend battery life in portable electronics.
Edge AI and Sensor Fusion
Uses the CORDIC and Filter Mathematical Accelerator (FMAC) to offload complex DSP tasks from the main CPU.
Industrial Instrumentation
Integrates a wide range of serial interfaces including CANbus, SPI, and USB OTG for robust communication in factory environments.

Getting Started

Start development using the STM32CubeU5 software suite, which includes the STM32CubeIDE and initialization code generators. For hardware evaluation, the NUCLEO-U575ZI-Q or the B-U585I-IOT02A Discovery kit provides a direct path to testing the U5 series features. Ensure you leverage the Power Shield (X-NUCLEO-LPM01A) to accurately measure the ultra-low-power consumption modes during firmware optimization.
