Product details

Overview

STM32U575QGI6TR 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 supports LPBAM autonomous peripheral operation down to Stop 2 mode. Designed for secure, battery-constrained edge nodes, it delivers 450 ULPMark™-CP and operates across –40 °C to +85 °C.

For engineers reviewing the STM32U575QGI6TR datasheet, STM32U575QGI6TR pinout, STM32U575QGI6TR application, or STM32U575QGI6TR equivalent, key selection criteria include TrustZone-enabled secure boot, sub-µA low-power modes (e.g., 160 nA Shutdown), dual 14-/12-bit ADCs with Stop 2 autonomy, CAN FD interface, and UFBGA132 package compatibility with space-constrained industrial sensor hubs and portable medical devices.

Technical Context

The device implements a dual-bank Flash architecture enabling read-while-write and secure firmware installation (SFI) via embedded Root Secure Services (RSS). Its power system combines an LDO and SMPS step-down converter with on-the-fly voltage scaling, supporting dynamic transition between Run (19.5 µA/MHz @ 3.3 V) and Stop 3 (1.9 µA with 16-KB SRAM) modes.

TrustZone® partitions memory, peripherals, and I/Os into secure/non-secure worlds, enforced by the Global TrustZone Controller (GTZC) and securable SYSCFG. The ART Accelerator includes 8-KB instruction cache and 4-KB data cache, enabling zero-wait-state execution at up to 160 MHz while maintaining deterministic timing for real-time control loops.

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
STM32L562VEJ6	Same Cortex-M33 + TrustZone, but 512 KB Flash, 256 KB SRAM, no UCPD or CAN FD; lower ULPMark-CP (345 vs. 450).	Suitable for cost-sensitive, non-USB-PD applications where CAN FD and extended memory are unnecessary.	Select when footprint compatibility with LQFP100 is required and USB Type-C negotiation is not needed.
NXP LPC55S69JBD100	Cortex-M33 + TrustZone, 640 KB Flash, 320 KB SRAM, no integrated SMPS, higher active current (24 µA/MHz), lacks LPBAM and Octo-SPI.	Better suited for audio-centric designs with multiple I²S interfaces, but less optimal for battery lifetime-critical sensor nodes.	Prefer when leveraging NXP's MCUXpresso SDK ecosystem and requiring dual-core asymmetric operation (Cortex-M33 + Cortex-M0+).

Compared with STM32L562VEJ6, the STM32U575QGI6TR offers 4× more Flash, CAN FD, and USB Type-C/USB PD-making it superior for future-proof industrial gateways. Against LPC55S69JBD100, its LPBAM, SMPS, and 160 nA Shutdown deliver significantly longer battery life in always-on edge sensing.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating?

The STM32U575QGI6TR achieves a maximum CPU frequency of 160 MHz, delivering 240 DMIPS (Dhrystone 2.1) performance. This is enabled by the ART Accelerator's 8-KB instruction cache, which eliminates flash wait states. The core also supports DSP instructions and a single-precision FPU for efficient floating-point computation in control and signal-processing applications.

Does this MCU support secure boot and runtime attestation?

Yes. The device implements a hardware-enforced secure boot chain starting from ROM-based first-stage bootloader (FSBL), verifying signed firmware images using public-key cryptography. Runtime attestation is supported via TrustZone-isolated secure monitor calls and the HASH accelerator, enabling remote verification of firmware integrity and execution state without exposing secrets.

What low-power modes are available, and what is the lowest achievable current draw?

Seven low-power modes are supported: Shutdown (160 nA), Standby (210 nA), Standby with RTC (530 nA), Stop 2 (4.0–8.95 µA), Stop 3 (1.9–4.3 µA), and two Run modes with voltage scaling. The lowest current is 160 nA in Shutdown mode with 24 configurable wake-up pins-ideal for long-term battery-backed applications like utility meters and environmental sensors.

Is the UFBGA132 package RoHS-compliant and suitable for reflow soldering?

Yes. The STM32U575QGI6TR in UFBGA132 (A0G8) packaging is ECOPACK2-compliant and qualified for standard Pb-free reflow soldering per JEDEC J-STD-020. Its 0.5 mm ball pitch and 7 × 7 mm footprint meet IPC-7351B standards, supporting automated assembly in high-volume manufacturing with controlled thermal profiles.
