Product details

Overview

STM32U575CGT6Q 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 STM32U575CGT6Q datasheet, STM32U575CGT6Q pinout, STM32U575CGT6Q application, or STM32U575CGT6Q equivalent, key selection criteria include TrustZone-enabled secure boot, 160 nA Shutdown mode, 14-bit 2.5-Msps ADC with hardware oversampling, and dual Octo-SPI interfaces for external memory expansion.

Technical Context

The STM32U575CGT6Q implements a dual-bank Flash architecture with read-while-write capability and ECC protection, enabling safe firmware updates without halting execution. Its FlexPowerControl system combines LDO and SMPS regulators with dynamic voltage scaling, allowing real-time power mode transitions between Run (19.5 µA/MHz) and Stop 3 (1.9 µA with 16 KB SRAM retained).

TrustZone security is hardware-enforced across memory (Flash/SRAM), peripherals (I/Os, timers, ADCs), and boot flow - anchored by unique boot entry, secure hide protection area (HDP), and embedded root secure services (RSS) for secure firmware installation. The CORDIC and FMAC coprocessors accelerate trigonometric and filter computations independently of the CPU.

Pinout & Package

STM32U575CGT6Q uses the UFQFPN48 (7 × 7 mm) package with 48 pins, optimized for space-constrained portable and wearable designs. Pin functions are validated per STMicroelectronics DS13737 Rev 10 Section 4.2 (Pin description) and Table 12 (Pin mapping for UFQFPN48).

Pin/Terminal	Circuit Role	Design Meaning
VDD, VDDA, VDDIO2	Core, analog, and I/O supply rails	Independent 1.71–3.6 V domains enable mixed-voltage I/O (up to 5 V tolerant on most pins) and low-noise analog operation.
PA0–PA15, PB0–PB15, etc.	General-purpose I/Os	Up to 136 fast I/Os with interrupt capability; 14 support independent 1.08–3.6 V supply for interfacing with low-voltage peripherals.

BOOT0	Boot mode selection	Configures boot source (system memory, main Flash, or SRAM); sampled at reset and latched for secure boot enforcement.

Key Features

Feature	Design Value
LPBAM (Low-Power Background Autonomous Mode)	Enables 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	Integrated step-down DC-DC converter replaces external regulator; achieves >85% efficiency at 100 mA and supports seamless on-the-fly switching between LDO/SMPS during voltage scaling.
Chrom-ART Accelerator (DMA2D)	Hardware-accelerated 2D graphics rendering offloads CPU for GUI-driven HMI applications - supports ARGB8888 blending and memory-to-memory transfers.
Secure Firmware Installation (SFI)	Root-of-trust boot process using embedded RSS validates firmware signature before execution - prevents unauthorized code injection during field updates.
VBAT domain retention	Maintains RTC operation, 32×32-bit backup registers, and 2 KB backup SRAM during main power loss - preserves time, state, and calibration data across power cycles.

Use Value: 14-bit 2.5-Msps ADC with hardware oversampling captures high-fidelity biosignals; 1.9 µA Stop 3 mode preserves SRAM context between heartbeat-triggered wake-ups.

Industrial Wireless Sensor Node

Secure Edge Gateway

Use Scenario: LoRaWAN or Thread endpoint collecting temperature, humidity, and vibration data in factory environments.

IC Role / Device Role / Timing Role: Low-power host MCU executing sensor fusion algorithms, managing radio sleep/wake cycles, and enforcing secure OTA update policies.

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
STM32L562VET6	Same Cortex-M33 core and TrustZone, but only 512 KB Flash, 256 KB SRAM, no Octo-SPI, and lower ULPMark™-CP (340 vs. 450).	Targeted at cost-sensitive, lower-feature edge nodes without external memory expansion needs.	Select when Flash/SRAM requirements are ≤512 KB and dual Octo-SPI is unnecessary - offers smaller footprint (LQFP100 vs. UFQFPN48) and lower BOM cost.
NXP KW38	ARM Cortex-M4F core without TrustZone, integrated BLE 5.0 radio, 512 KB Flash, 128 KB SRAM, no CAN FD or Octo-SPI.	Optimized for BLE-centric wireless sensor hubs where radio integration outweighs general-purpose compute and security depth.	Choose when native BLE connectivity is mandatory and hardware-enforced security isolation is secondary to RF integration and antenna matching simplicity.

Compared with STM32L562VET6, the STM32U575CGT6Q delivers 4× more Flash, dual Octo-SPI, and superior ultra-low-power metrics; versus KW38, it trades integrated BLE for deeper TrustZone isolation, CAN FD, and deterministic real-time performance - making it optimal for certified industrial gateways and secure metering.

FAQ

What is the maximum operating temperature range for STM32U575CGT6Q?

The STM32U575CGT6Q is rated for –40 °C to +125 °C ambient operation, validated per DS13737 Rev 10 Section 5.3.1. This extended range supports deployment in harsh industrial environments such as motor control cabinets and outdoor utility enclosures without derating.

Does STM32U575CGT6Q support hardware-accelerated cryptography beyond HASH?

Yes - in addition to the HASH accelerator, it includes a NIST SP800-90B-compliant True Random Number Generator (TRNG), 96-bit unique ID, 512-byte one-time programmable (OTP) memory, and secure boot ROM with embedded Root Secure Services (RSS) for authenticated firmware loading and TF-M-based secure firmware upgrades.

Can STM32U575CGT6Q operate from a single-cell Li-ion battery without external regulators?

Yes - its integrated SMPS step-down converter accepts 1.71–3.6 V input and supports direct connection to a single-cell Li-ion (2.7–4.2 V) with external inductor/capacitor. The SMPS can be dynamically switched with the LDO during runtime to optimize efficiency across load conditions, as specified in Section 3.9.1 of the datasheet.

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

The STM32U575CGT6Q provides 24 dedicated wake-up pins in Standby mode, confirmed in DS13737 Rev 10 Section 3.9.3. These pins retain interrupt capability while consuming only 210 nA (without RTC) or 530 nA (with RTC enabled), enabling responsive event-driven operation in battery-critical applications.
