Product details

Overview

STM32U575CGU6Q from STMicroelectronics is an ultra-low-power Arm® Cortex®-M33 32-bit microcontroller with TrustZone® security, FPU, and 240 DMIPS performance. It integrates 2 MB Flash (with ECC), 786 KB SRAM, and operates from 1.71 V to 3.6 V across –40 °C to +125 °C. Designed for battery-powered edge nodes, it delivers 19.5 µA/MHz in Run mode and supports autonomous low-power background operation (LPBAM) down to Stop 2 mode.

For engineers reviewing the STM32U575CGU6Q datasheet, STM32U575CGU6Q pinout, STM32U575CGU6Q application, or STM32U575CGU6Q equivalent, key selection criteria include TrustZone-enabled secure boot, sub-µA Stop modes with RTC retention, dual 14-/12-bit ADCs with hardware oversampling, CAN FD interface, and UFQFPN48 package compatibility with space-constrained industrial sensors and portable medical devices.

Technical Context

The STM32U575CGU6Q implements a dual-bank Flash architecture enabling read-while-write operations and secure firmware installation (SFI) via embedded Root Secure Services (RSS). Its power architecture combines an LDO and SMPS step-down converter with dynamic voltage scaling and on-the-fly switching to optimize efficiency across operating modes.

TrustZone® partitions memory and peripherals into secure/non-secure worlds, enforced by the Global TrustZone Controller (GTZC), while the ART Accelerator includes 8 KB instruction cache and 4 KB data cache to sustain zero-wait-state execution at up to 160 MHz - critical for deterministic real-time control in safety-aware applications.

Key Specifications

Max Clock Speed	160 MHz - supports 240 DMIPS performance and zero-wait-state execution via 8 KB instruction cache.
Flash Memory	2 MB with ECC, dual-bank, 100 kcycle endurance - allows safe over-the-air updates and concurrent code execution/programming.
SRAM	786 KB total (722 KB with ECC ON) - provides large buffer space for sensor fusion, audio preprocessing, or secure TLS stacks.
Low-Power Modes	160 nA Shutdown, 530 nA Standby with RTC, 4.3 µA Stop 3 with full SRAM - extends battery life in always-on IoT endpoints.
Analog Peripherals	14-bit 2.5-Msps ADC (autonomous in Stop 2), dual 12-bit DACs, 2 op-amps with PGA, 2 ultra-low-power comparators - supports precision analog sensing without waking CPU.
Communication	1 CAN FD, 6 USARTs, 4 I²C (FM+), 2 SAI, USB OTG FS, UCPD, 2 SDMMC - enables robust connectivity for industrial gateways and USB-C powered devices.

Pinout & Package

STM32U575CGU6Q is housed in a 7 × 7 mm UFQFPN48 package (pitch: 0.5 mm), optimized for compact PCB layouts in space-constrained applications. The package features exposed thermal pad for enhanced heat dissipation and supports reflow soldering per JEDEC J-STD-020.

Pin/Terminal	Circuit Role	Design Meaning
VDD, VSS	Main power supply and ground	Supports 1.71–3.6 V operation; multiple pins ensure low-impedance power delivery and noise immunity.
VDDA, VSSA	Analog power and ground	Independent analog domain supply enables high-precision ADC/DAC operation with reduced digital coupling noise.
PA0–PA15, PB0–PB15, etc.	General-purpose I/Os	Up to 136 fast I/Os; most are 5 V-tolerant and support interrupt generation - simplifies level-shifting in mixed-voltage systems.
BOOT0	Boot mode selection	Configures boot source (system memory, main Flash, or SRAM); critical for secure bootloader initialization and field recovery.
NRST	Reset input	Active-low reset with internal pull-up; accepts external reset signals or watchdog timeout pulses to guarantee deterministic system restart.
VBAT	Backup power supply	Supplies RTC, 32×32-bit backup registers, and 2 KB backup SRAM during main power loss - preserves timekeeping and state across power cycles.

Key Features

Feature	Design Value
Low-Power Background Autonomous Mode (LPBAM)	Enables DMA-driven peripheral chains (e.g., ADC → memory → timer → GPIO) without CPU intervention - reduces active time and extends battery life in sensor nodes.
Secure Boot & Firmware Upgrade	Leverages TrustZone, RDP, HDP, and TF-M integration to enforce authenticated, encrypted firmware loading and over-the-air updates - meets PSA Level 3 and SESIP certification requirements.
ART Accelerator with ICACHE/DCACHE	8 KB instruction cache + 4 KB data cache eliminate wait states for Flash and external memory access - sustains 160 MHz core frequency with predictable timing for real-time control loops.
Dual High-Resolution ADCs	14-bit 2.5-Msps ADC1 and 12-bit 2.5-Msps ADC4 both support hardware oversampling and operate autonomously in Stop 2 mode - enables continuous sensor monitoring at <1 µA system current.
Integrated Power Management	Embedded SMPS + LDO with on-the-fly switching and voltage scaling - achieves >90% conversion efficiency across load ranges and dynamically adapts to performance vs. power trade-offs.

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
STM32U585QIT6Q	Same U5 series, but adds integrated SMPS controller (vs. SMPS regulator in U575), higher temp grade (+125 °C), and 1 MB more Flash (3 MB).	Targeted at higher-power edge AI inference or multi-sensor fusion where extended Flash and tighter thermal management are required.	Select when needing >2 MB Flash, integrated SMPS control logic, or guaranteed operation above +105 °C ambient.
RA4M3GDBM20#AC0	Renesas RA4M3 with Cortex-M33, 1 MB Flash, 384 KB SRAM, no TrustZone hardware partitioning, lower ULPMark™-CP (380).	Suitable for cost-sensitive industrial HMI or motor control where full PSA-certified security is not mandated.	Choose for simpler security models, lower BOM cost, or existing Renesas ecosystem alignment - but verify absence of hardware-enforced memory isolation.

Compared with STM32U575CGU6Q, the STM32U585QIT6Q offers greater Flash headroom and tighter thermal specs for demanding edge compute, while the RA4M3GDBM20#AC0 trades TrustZone enforcement and ultra-low-power benchmarks for lower unit cost and simplified toolchain integration.

FAQ

What is the maximum operating temperature for STM32U575CGU6Q?

The STM32U575CGU6Q is qualified for operation from –40 °C to +125 °C ambient temperature, meeting industrial and extended-temperature requirements. This rating is validated per ST's production test flow and applies to all package variants including the UFQFPN48, with thermal derating guidelines provided in Section 6.9 of DS13737 Rev 10.

Does STM32U575CGU6Q support hardware-based secure boot?

Yes - it implements a root-of-trust via unique boot entry, secure hide protection area (HDP), and flexible life cycle scheme with Read-Out Protection (RDP). Secure firmware installation (SFI) is enabled through embedded Root Secure Services (RSS), and TrustZone enforces strict isolation between secure and non-secure firmware images during boot and runtime.

Which low-power modes retain SRAM content and RTC functionality?

Stop 2, Stop 3, Standby, and VBAT modes retain full SRAM content and RTC operation. Specifically, Stop 2 retains up to 16 KB SRAM at 4.0 µA, Stop 3 retains full 786 KB SRAM at 4.3 µA, Standby with RTC consumes 530 nA, and VBAT mode maintains RTC, 32×32-bit backup registers, and 2 KB backup SRAM using external coin-cell power.

Is the UFQFPN48 package RoHS and ECOPACK2 compliant?

Yes - the UFQFPN48 package for STM32U575CGU6Q complies with RoHS Directive 2011/65/EU and ECOPACK2 standards, including halogen-free materials and lead-free terminations.
