STM32U585QII6
Overview
The STM32U585QII6 is a high-performance, ultra-low-power microcontroller based on the ARM Cortex-M33 core with TrustZone and FPU, operating at up to 160MHz. It features 2MB of Flash and 784KB of RAM, specifically designed for applications requiring high security and efficient power consumption. The device includes a built-in SMPS for optimized power delivery and is certified for PSA Level 3 and SESIP3 security standards.
Why Choose This Part
The STM32U585 offers a class-leading balance of 160MHz performance and efficiency, drawing only 10.50mA at full speed when using the internal SMPS. Its comprehensive security suite, including hardware encryption and lifecycle management, meets the highest industry certifications for secure embedded systems. The large 2MB Flash and 784KB RAM satisfy the memory demands of modern RTOS and graphics stacks in a compact 132-UFBGA package.
