Overview

The STM32U585AII6Q is a high-performance, ultra-low-power microcontroller based on the ARM Cortex-M33 core with TrustZone and a Floating Point Unit (FPU). Operating at up to 160 MHz, it integrates 2 MB of Flash memory and advanced security features, making it a flagship choice for the STM32U5 series. It is designed to bridge the gap between high processing requirements and strict power consumption limits in battery-operated systems.

Why Choose This Part

This MCU features the LPBAM (Low Power Background Autonomous Mode) which allows peripherals to operate while the CPU is in sleep, significantly reducing average current draw. The inclusion of hardware-based security certifications and 2 MB of dual-bank Flash provides ample headroom for complex application code and secure over-the-air (OTA) updates.

Applications

Secure IoT Edge Nodes
Leveraging TrustZone and hardware cryptographic accelerators to secure sensitive data and firmware updates in connected devices.
Wearable Health Monitors
Utilizing ultra-low-power modes and integrated FPU for real-time biometric signal processing on a limited power budget.
Industrial Sensor Hubs
Managing high-speed data acquisition from multiple sensors with low latency while maintaining minimal thermal output in small enclosures.
