STMicroelectronics STM32U575OGY6QTR

Overview

STM32U575OGY6QTR from STMicroelectronics is an ultra-low-power Arm® Cortex®-M33 32-bit MCU with TrustZone®, FPU, and FlexPowerControl, delivering 240 DMIPS at up to 160 MHz. It integrates 2 MB Flash (ECC), 786 KB SRAM (ECC configurable), and supports LPBAM for autonomous peripheral operation down to Stop 2 mode. Used in battery-powered industrial sensors and secure IoT edge nodes requiring long runtime and cryptographic integrity.

For engineers reviewing the STM32U575OGY6QTR datasheet, STM32U575OGY6QTR pinout, STM32U575OGY6QTR application, or STM32U575OGY6QTR equivalent, key selection criteria include TrustZone-enabled secure boot, ULPMark™-CP score of 450, 160 nA Shutdown mode, and dual 14-/12-bit ADCs with hardware oversampling in Stop 2.

Technical Context

The device implements Arm TrustZone® for hardware-enforced isolation between secure and non-secure firmware execution, with root-of-trust established via unique boot entry and HDP-protected secure hide area. Its FlexPowerControl architecture enables dynamic voltage scaling and on-the-fly SMPS/LDO switching to optimize power across operating modes.

Core peripherals include two independent 14-bit/12-bit ADCs (2.5 Msps with oversampling), dual DACs, two op-amps with PGA, and a CORDIC/FMAC coprocessor for real-time trigonometric and filtering math. The GPDMA and LPDMA controllers remain functional in Stop modes, enabling sensor data acquisition without CPU wake-up.

FAQ

What is the maximum operating frequency and associated DMIPS rating?

The STM32U575OGY6QTR operates at up to 160 MHz, achieving 240 DMIPS per the Dhrystone 2.1 benchmark. This performance is sustained with zero-wait-state execution from Flash thanks to the 8 KB instruction cache (ART Accelerator), making it suitable for real-time control and signal processing in battery-constrained systems.

Does this MCU support hardware-accelerated cryptography beyond HASH and TRNG?

Yes - it includes dedicated accelerators for AES-128/256 (via CRYP peripheral), SHA-1/SHA-256 (HASH), and public-key operations (RSA/ECC via PKA). These are accessible through the STM32CubeU5 HAL libraries and validated against NIST CAVP test vectors, enabling TLS 1.2/1.3 handshakes in under 100 ms.

How does LPBAM differ from traditional DMA-based low-power operation?

LPBAM extends standard DMA by enabling full peripheral-to-peripheral data chains (e.g., ADC → memory → timer → DAC) without CPU intervention - even in Stop 2 mode. Unlike conventional DMA, it uses dedicated low-power triggers and state machines, reducing wake-up latency by up to 50% and eliminating CPU clock gating overhead in sensor aggregation workflows.

What package variant and RoHS status does STM32U575OGY6QTR use?

STM32U575OGY6QTR uses the UFQFPN48 (7 × 7 mm) package with 0.5 mm pitch and is ECOPACK2-compliant - meeting RoHS Directive 2011/65/EU and REACH SVHC requirements. The "QTR" suffix denotes tape-and-reel packaging for automated SMT assembly, with moisture sensitivity level (MSL) 3 per J-STD-020.
