STMicroelectronics STM32U575ZIT6Q

Overview

STM32U575ZIT6Q 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 secure, battery-constrained edge nodes, it delivers 450 ULPMark™-CP and supports autonomous low-power background operation (LPBAM) down to Stop 2 mode.

For engineers reviewing the STM32U575ZIT6Q datasheet, STM32U575ZIT6Q pinout, STM32U575ZIT6Q application, or STM32U575ZIT6Q equivalent, key selection considerations include its dual-bank read-while-write Flash, 14-bit 2.5-Msps ADC with hardware oversampling, TrustZone-enabled peripheral isolation, and UFBGA132 (7 × 7 mm) package with 136 fast I/Os - critical for secure IoT sensor hubs, industrial telemetry endpoints, and medical wearables requiring certified firmware integrity and sub-μA standby.

Technical Context

The STM32U575ZIT6Q implements a dual-core security architecture: the Cortex-M33 core executes in both Secure and Non-secure states, enforced by TrustZone memory and peripheral protection, while the GTZC (Global TrustZone Controller) enables runtime reconfiguration of securable resources. Its FlexPowerControl system combines SMPS + LDO regulation, voltage scaling, and dynamic clock gating to achieve 160 nA Shutdown mode and 530 nA Standby with RTC.

Peripheral autonomy is enabled via LPBAM - allowing DMA-driven sequences across timers, ADCs, and communication interfaces without CPU wake-up - and supported by two independent DMA controllers (GPDMA and LPDMA), both functional in Stop modes. The device includes three PLLs (system, USB, audio), dual Octo-SPI interfaces, and a CAN FD controller, enabling concurrent high-bandwidth memory access, real-time networking, and secure firmware updates via TF-M.

Key Specifications

Pinout & Package

STM32U575ZIT6Q is housed in a 132-ball UFBGA package (7 × 7 mm, 0.5 mm pitch), optimized for compact, thermally constrained PCB layouts. Pin assignment follows ST's standardized UFBGA132 footprint (package code A0G8), with VDD/VSS pairs distributed for low-noise power delivery and dedicated VREF+/- pins for precision analog operation.

FAQ

What is the maximum operating temperature range for STM32U575ZIT6Q?

The STM32U575ZIT6Q is qualified for operation from –40 °C to +125 °C ambient temperature, validated per industrial-grade specifications. This extended range supports deployment in harsh environments such as under-hood automotive modules, outdoor utility meters, and factory-floor controllers where thermal stress exceeds standard commercial limits.

Does STM32U575ZIT6Q support hardware-based secure boot?

Yes - it implements a root-of-trust boot sequence anchored in immutable ROM code, verified boot using SHA-256 hash and public-key signature (ECDSA P-256), and secure hide protection area (HDP) for bootloader confidentiality. Boot integrity is enforced before any user code executes, and debug access is disabled unless RDP level permits.

How many I/O pins support independent 1.08 V supply?

Up to 14 I/O pins (grouped as VDDIO2 domain) support independent supply down to 1.08 V, enabling direct interfacing with ultra-low-voltage peripherals like certain MEMS sensors or energy-harvesting PMUs without level shifters - critical for minimizing BOM count in self-powered edge nodes.

Can STM32U575ZIT6Q run TF-M (Trusted Firmware-M) out of the box?

Yes - ST provides official TF-M porting layers and pre-certified images for the STM32U5 series, including the ZIT6Q variant. The device's TrustZone-enforced memory isolation, secure boot, and hardware crypto accelerators (HASH, TRNG, PKA) meet TF-M v1.7+ requirements for PSA Certified Level 3, enabling immediate integration into PSA-compliant firmware architectures.
