Product details

Overview

STM32U575VIT6Q 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, dual 14-/12-bit ADCs, 2 DACs, 2 op-amps, CAN FD, USB Type-C®/PD controller, and Octo-SPI - deployed in battery-powered industrial sensors and secure edge nodes.

For engineers reviewing the STM32U575VIT6Q datasheet, STM32U575VIT6Q pinout, STM32U575VIT6Q application, or STM32U575VIT6Q equivalent, key selection criteria include TrustZone-enabled secure boot, sub-µA Stop 3 mode (1.9 µA with 16-KB SRAM), LPBAM autonomous peripheral operation, 136 GPIOs (most 5V-tolerant), and UFBGA100 package compatibility for space-constrained designs.

Technical Context

The STM32U575VIT6Q implements a dual-bank Flash architecture supporting read-while-write and 100 kcycle endurance on 512 KB, paired with ECC-capable SRAM (722 KB with ECC ON). Its power system combines embedded LDO and SMPS step-down converter with dynamic voltage scaling and switch-on-the-fly capability for optimal efficiency across operating modes.

TrustZone® enforces hardware-isolated secure/non-secure worlds, with GTZC managing memory, peripheral, and I/O securability. The device supports secure firmware installation (SFI) via embedded root secure services (RSS) and TF-M–based firmware upgrades, while CORDIC and FMAC coprocessors accelerate trigonometric and filter computations without CPU load.

Pinout & Package

STM32U575VIT6Q is housed in a 100-pin LQFP (14 × 14 mm, 0.5 mm pitch) package, designated as part number code '1L' per ST's ordering matrix. This package supports full peripheral mapping including dual ADC inputs, Octo-SPI signals, USB D+/D−, CAN FD TX/RX, and all 136 GPIOs (with 14 independently supplied down to 1.08 V).

Pin/Terminal	Circuit Role	Design Meaning
VDD, VDDA, VDDIO2	Power supply domains	VDD (1.71–3.6 V core), VDDA (analog domain), VDDIO2 (I/O bank 2) enable independent voltage scaling and noise isolation for mixed-signal operation.
PA0–PA15, PB0–PB15, etc.	General-purpose I/O	136 fast GPIOs with interrupt capability; most 5V-tolerant, up to 14 support independent 1.08–3.6 V supply - simplifies level-shifting in heterogeneous subsystems.

Use Value: Dual ADCs sample synchronized analog channels at 2.5 Msps; Stop 3 mode with 16-KB SRAM preserves context between 15-minute wake intervals - cuts energy per measurement by 4×.

Secure Edge Gateway

Medical Wearable Monitor

Use Scenario: Field-deployed gateway connecting Modbus RTU devices to cloud via cellular or Ethernet, requiring TLS encryption and firmware signing.

IC Role / Device Role / Timing Role: Secure host processor running TF-M, handling TLS handshake acceleration via HASH + TRNG, and managing CAN FD/USB Type-C interfaces.

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
STM32U585AII6	Same U5 series, but adds AES-256/HSM and higher-temp grade (–40 °C to +125 °C); 144-pin TFBGA vs. 100-pin LQFP.	Required for automotive under-hood or industrial high-temp environments where extended thermal range and certified HSM are mandatory.	Select when hardware security module certification (e.g., PSA Certified Level 3) and >85 °C ambient operation are required - not drop-in due to package and pinout change.
RA4M3GFP	Renesas RA4M3 with Cortex-M33, 1 MB Flash, 384 KB SRAM, no TrustZone-based memory isolation; lower ULPMark™-CP (380 vs. 450).	Suitable for cost-sensitive consumer IoT where basic secure boot suffices but advanced peripheral autonomy (LPBAM) and ECC memory are non-critical.	Choose for simpler BOMs and toolchain continuity in Renesas ecosystems - lacks VBAT domain, Octo-SPI, and sub-µA shutdown modes of STM32U575.

Compared with STM32U575VIT6Q, STM32U585AII6 offers enhanced security certification and thermal range at the cost of larger footprint and non-compatible pinout, while RA4M3GFP trades ultra-low-power precision and TrustZone granularity for lower unit cost and simpler integration in less demanding environments.

FAQ

What is the maximum operating temperature for STM32U575VIT6Q?

The STM32U575VIT6Q is rated for industrial temperature range: –40 °C to +85 °C. Its datasheet specifies full functionality and guaranteed electrical characteristics across this range, including all low-power modes, ADC accuracy, and Flash write/erase endurance. No derating is required within these limits.

Does STM32U575VIT6Q support external memory interfaces beyond Octo-SPI?

Yes - it integrates a Flexible Static Memory Controller (FSMC) supporting SRAM, PSRAM, NOR, NAND, and FRAM memories with address/data bus multiplexing. Unlike Octo-SPI (optimized for serial flash), FSMC provides parallel 8-/16-bit access with configurable timing, enabling legacy memory compatibility and high-throughput frame buffers.

How does TrustZone implementation differ between STM32U575VIT6Q and earlier STM32L5 devices?

STM32U575VIT6Q enhances TrustZone with Global TrustZone Controller (GTZC) managing memory, peripheral, and I/O security classification - unlike STM32L5's fixed peripheral assignment. It also adds secure hide protection area (HDP) and root-of-trust boot entry, enabling certified secure firmware installation (SFI) and TF-M–based updates not available in L5.

Can the 14-bit ADC operate autonomously in Stop 2 mode?

No - only the 12-bit ADC4 supports autonomous conversion in Stop 2 mode. The 14-bit ADC1 requires the CPU or DMA to be active and cannot initiate conversions while the core is stopped. This distinction is documented in Section 3.28.1 and Table 54 of DS13737 Rev 10.
