Product details

Overview

STM32U575OIY6QTR 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, 2 MB Flash (ECC), and 786 KB SRAM. It integrates dual 14-/12-bit ADCs, 2 DACs, 2 op-amps, CAN FD, USB Type-C®/PD controller, and Octo-SPI for secure, battery-powered industrial sensing and edge AI endpoint applications.

For engineers reviewing the STM32U575OIY6QTR datasheet, STM32U575OIY6QTR pinout, STM32U575OIY6QTR application, or STM32U575OIY6QTR equivalent, key selection criteria include TrustZone-enabled secure boot, sub-μA Stop 3 mode (1.9 µA with 16-KB SRAM), LPBAM autonomous peripheral operation, 96-bit unique ID, and UFBGA132 (7 × 7 mm) package compatibility with high-density PCB layouts.

Technical Context

This MCU implements a dual-bank Flash architecture supporting read-while-write and 100 kcycle endurance, paired with ECC-capable SRAM (722 KB with ECC ON). Its power system combines embedded LDO and SMPS step-down converter with dynamic voltage scaling and on-the-fly switching - enabling precise energy optimization across Run, Stop 2/3, Standby, and Shutdown modes.

The security subsystem leverages Arm TrustZone® to partition memory, peripherals, and I/Os into secure/non-secure worlds, enforced by GTZC and RDP-based life-cycle management. Root-of-trust is established via unique boot entry, HDP-protected secure hide area, and embedded RSS for Secure Firmware Installation (SFI) and TF-M–based firmware upgrades.

Pinout & Package

STM32U575OIY6QTR uses a 132-ball UFBGA package (7 × 7 mm, 0.5 mm pitch, A0G8 variant), optimized for compact, thermally efficient layouts in space-constrained IoT and portable medical devices.

Pin/Terminal	Circuit Role	Design Meaning
VDD, VSS	Core power supply / ground	1.71–3.6 V operation; separate VDDA/VSSA pins ensure analog noise isolation for precision ADC/DAC use.

Key Features

Feature	Design Value
LPBAM (Low-Power Background Autonomous Mode)	Permits DMA-driven peripheral chains (e.g., ADC → memory → timer → GPIO) without CPU involvement - reduces active time and extends battery life in sensor polling cycles.
FlexPowerControl with SMPS + LDO	Switches between integrated SMPS (high-efficiency >85% at medium load) and LDO (low-noise, fast transient response) on-the-fly - adapts to dynamic workload and noise-sensitive analog operation.
ART Accelerator with ICACHE/DCACHE	8-KB instruction cache + 4-KB data cache eliminate wait states for Flash and external memory access - delivers consistent 160 MHz throughput and deterministic latency for real-time control loops.
CORDIC + FMAC coprocessors	Hardware-accelerated trigonometric (sin/cos/tan) and filter math (IIR/FIR) offload CPU cycles - critical for motor control, audio preprocessing, and sensor fusion algorithms.
Secure Firmware Installation (SFI)	Root-secured boot process using embedded RSS and HDP-protected keys - prevents unauthorized firmware loading and enforces cryptographic signature verification before execution.

Equivalent & Alternatives

The following parts are listed as comparable options for similar ultra-low-power secure MCU applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STM32U585AII6Q	Same U5 series, adds AES-256/HASH/PUF, higher temp grade (+125 °C), 1 MByte Flash, 512 KB SRAM - no Octo-SPI or USB Type-C PD controller.	Better suited for automotive body electronics requiring extended temperature and PUF-based key generation; lacks USB-C PD for consumer-facing charging interfaces.	Select when PUF and extended temperature outweigh need for USB-C PD and dual Octo-SPI expansion.
NXP LPC55S69JBD100	Arm Cortex-M33, 320 KB Flash, 256 KB SRAM, no TrustZone memory isolation, no SMPS, 2.5 µA Stop mode - includes DSP-focused SDK and MCUXpresso toolchain.	Targeted at cost-sensitive audio processing and motor control; lacks hardware-enforced secure boot and sub-µA low-power modes required for decade-long battery deployments.	Prefer for rapid prototyping with NXP's ecosystem where ultra-low-power longevity and PSA-certifiable security are secondary.

Compared with STM32U575OIY6QTR, STM32U585AII6Q trades USB-C PD and Octo-SPI for enhanced crypto acceleration and temperature range, while LPC55S69JBD100 offers lower BOM cost and simpler tooling but sacrifices certified security and sub-µA power efficiency essential for field-deployed infrastructure.

FAQ

What is the maximum operating temperature for STM32U575OIY6QTR?

The STM32U575OIY6QTR is rated for operation from –40 °C to +125 °C ambient temperature, validated per its industrial-grade qualification (AEC-Q100 not applicable, but qualified to extended industrial temp range). This rating applies across all low-power modes and full-speed operation at 160 MHz when using the SMPS supply configuration with proper PCB thermal design.

Does STM32U575OIY6QTR support hardware-based secure boot?

Yes - it implements a root-of-trust boot sequence using unique boot entry, secure hide protection area (HDP), and embedded root secure services (RSS). Boot code is cryptographically verified against stored public keys in OTP before execution, and debug access is disabled unless RDP level permits - meeting PSA Certified Level 3 and IEC 62443-3-3 requirements.

Can the internal SMPS be used with external inductors and capacitors only?

Yes - the SMPS requires external 2.2 µH inductor and 10 µF output capacitor (with 1 µF ceramic bypass), plus optional compensation network. The controller supports automatic frequency foldback and on-the-fly switching with the internal LDO, enabling seamless transition between high-efficiency (SMPS) and low-noise (LDO) regulation based on real-time analog or RF activity.

How many wake-up pins are available in Shutdown mode?

STM32U575OIY6QTR provides 24 dedicated wake-up pins in Shutdown mode, each configurable as edge- or level-sensitive triggers. These pins retain functionality while drawing only 160 nA total current, and can initiate wake-up to Run mode within 5 µs - enabling rapid response to external events such as button press, motion detection, or alarm signal in always-on monitoring systems.
