Product details
Overview
STM32U575QGI3Q from STMicroelectronics is an ultra-low-power Arm® Cortex®-M33 32-bit microcontroller with TrustZone® security, FPU, and 240 DMIPS performance at up to 160 MHz. It integrates 2 MB Flash (with ECC), 786 KB SRAM (722 KB with ECC ON), 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 from 1.71 V to 3.6 V across –40 °C to +125 °C.
For engineers reviewing the STM32U575QGI3Q datasheet, STM32U575QGI3Q pinout, STM32U575QGI3Q application, or STM32U575QGI3Q equivalent, key selection criteria include TrustZone-enabled secure boot, sub-µA low-power modes (160 nA Shutdown), dual Octo-SPI interfaces, CAN FD support, and hardware accelerators (CORDIC, FMAC, HASH, RNG).
Technical Context
The STM32U575QGI3Q implements a dual-bank Arm Cortex-M33 core with TrustZone isolation, MPU, DSP extensions, and single-precision FPU. Its ART Accelerator includes 8-KB instruction cache and 4-KB data cache, enabling zero-wait-state execution from Flash and external memories.
Power architecture combines embedded LDO and SMPS step-down converter with dynamic voltage scaling and on-the-fly switching. Security relies on root-of-trust boot entry, Secure Hide Protection Area (HDP), and 512-byte OTP for firmware integrity-enabling certified secure firmware installation (SFI) and TF-M-based upgrades.

| FlexPowerControl with SMPS + LDO | Switch-on-the-fly between SMPS (high efficiency) and LDO (low noise) - optimizes power delivery for mixed analog/digital workloads. |
| Octo-SPI x2 interfaces | Supports XIP from high-density serial flash (up to 8 lines) - eliminates external parallel memory, reducing BOM and PCB area. |
| Hardware math accelerators (CORDIC + FMAC) | Offloads trigonometric and filter computations from CPU - cuts motor control loop latency by ~40% vs. software-only execution. |
| Secure Firmware Installation (SFI) | Root-secured boot services verify signed firmware images before execution - prevents unauthorized code injection in field-deployed devices. |

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 core but lacks UCPD, Octo-SPI, and FMAC; 512 KB Flash, no dual-bank RWW. | Suitable for cost-sensitive secure nodes without USB-C or high-speed serial memory needs. | Select when USB PD, XIP from Octo-SPI, or hardware filter acceleration are not required. |
| RA4M3GDB0 | Renesas RA4M3 with Cortex-M33, 1 MB Flash, 384 KB SRAM, no TrustZone-certified secure boot ROM or HDP. | Targets general-purpose industrial HMI where PSA Level 3 compliance is not mandated. | Choose if ecosystem preference (Flexible Software Package) outweighs ST's certified secure boot and tamper resilience. |

FAQ
What is the maximum operating temperature range for STM32U575QGI3Q?
The STM32U575QGI3Q is qualified for operation from –40 °C to +125 °C ambient temperature, meeting industrial and extended-temperature requirements. This rating applies to all package variants including the UFQFPN48, and is validated per JEDEC JESD47 stress testing standards.
Does STM32U575QGI3Q support hardware-accelerated cryptography beyond HASH and RNG?
No-this device integrates dedicated HASH (SHA-1/SHA-224/SHA-256) and NIST SP800-90B-compliant RNG accelerators, but does not include AES, ECC, or RSA engines. Cryptographic operations beyond hash and random generation require software libraries or external secure elements.
Can the 2 MB Flash be used for both code and data storage simultaneously?
Yes-the Flash is organized in two independent banks supporting true read-while-write (RWW) operation. One bank can execute code while the other is erased or programmed, enabling robust OTA firmware updates without halting application execution.
Is the UFQFPN48 package of STM32U575QGI3Q RoHS and REACH compliant?
Yes-STM32U575QGI3Q in UFQFPN48 packaging is ECOPACK2 compliant, satisfying RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, including full declaration of SVHC substances below threshold limits.
