Product details
Overview
STM32U575CGU3 from STMicroelectronics is an ultra-low-power Arm® Cortex®-M33 32-bit MCU with TrustZone® and FPU, delivering 240 DMIPS at up to 160 MHz. It integrates 2 MB Flash (with ECC), 786 KB SRAM, and supports LPBAM autonomous peripheral operation down to Stop 2 mode. Designed for battery-powered industrial sensors and secure IoT edge nodes requiring long runtime and cryptographic integrity.
For engineers reviewing the STM32U575CGU3 datasheet, STM32U575CGU3 pinout, STM32U575CGU3 application, or STM32U575CGU3 equivalent, key selection criteria include its 160 MHz max clock, 19.5 µA/MHz Run mode @ 3.3 V, TrustZone-enabled secure boot, dual 14-/12-bit ADCs with Stop 2 autonomy, and UCPD-based USB Type-C/Power Delivery controller integration.
Technical Context
The STM32U575CGU3 implements a dual-bank Flash architecture with read-while-write capability and hardware ECC, enabling safe over-the-air firmware updates. Its FlexPowerControl system combines LDO and SMPS regulators with dynamic voltage scaling and on-the-fly switching to optimize power across operating modes.
TrustZone security is implemented at silicon level with GTZC (Global TrustZone Controller), securable I/Os, memory regions, and peripherals - including secure hide protection area (HDP) and root-of-trust boot entry. The CORDIC and FMAC coprocessors accelerate trigonometric and filter computations without CPU load.

FAQ
What is the maximum operating frequency and associated performance metric?
The STM32U575CGU3 operates at up to 160 MHz, achieving 240 DMIPS (Dhrystone 2.1) and 651 CoreMark®. Its ART Accelerator with 8 KB instruction cache ensures zero-wait-state execution from Flash, enabling deterministic real-time response in motor control and sensor fusion tasks.
Does this MCU support secure firmware updates in the field?
Yes - it supports Secure Firmware Installation (SFI) via embedded Root Secure Services (RSS) and Secure Firmware Upgrade with TF-M (Trusted Firmware-M). These features enforce signature verification, encrypted image loading, and rollback protection using the 512-byte OTP and TrustZone-secured execution environment.
Which low-power modes retain SRAM content and how much is preserved?
In Stop 2 mode, up to 16 KB of SRAM is retained; in Stop 3, full 786 KB SRAM is preserved. Both modes maintain register state and allow wake-up via 24 dedicated pins. VBAT mode retains 2 KB backup SRAM and 32×32-bit registers independently of main supply.
What USB capabilities does the STM32U575CGU3 provide beyond standard OTG?
Beyond USB OTG 2.0 full-speed, it integrates a dedicated USB Type-C®/Power Delivery (UCPD) controller with hardware PD 3.0 protocol engine, supporting source/sink/DRP roles, VCONN switching, and BMC physical layer - enabling self-powered accessories and programmable power adapters without external PD controllers.
