Product details

Overview

STM32U575RGT6Q from STMicroelectronics is an ultra-low-power Arm® Cortex®-M33 32-bit MCU with TrustZone® security, 240 DMIPS performance, 2 MB Flash (ECC), 786 KB SRAM, and integrated SMPS regulator - deployed in battery-powered industrial sensors, secure IoT edge nodes, and medical wearables requiring <1.9 µA/MHz run current and hardware root-of-trust.

For engineers reviewing the STM32U575RGT6Q datasheet, STM32U575RGT6Q pinout, STM32U575RGT6Q application, or STM32U575RGT6Q equivalent, key selection criteria include TrustZone-enforced peripheral isolation, LPBAM autonomous peripheral operation in Stop 2 mode, 14-bit 2.5-Msps ADC with hardware oversampling, CAN FD + USB Type-C/USB PD controller integration, and UFBGA100 package compatibility for space-constrained designs.

Technical Context

The STM32U575RGT6Q implements a dual-bank Flash architecture with read-while-write capability and ECC protection, enabling secure firmware updates without runtime interruption. Its TrustZone security enforces strict memory and peripheral partitioning between secure/non-secure worlds, backed by a hardware root of trust via unique boot entry and HDP (Hide Protection Area).

Power management integrates an SMPS step-down converter with on-the-fly voltage scaling and LDO fallback, supporting dynamic transition between 160 MHz full-performance and sub-µA Stop 3 modes. The ART Accelerator includes 8-KB instruction cache and 4-KB data cache, delivering zero-wait-state execution from Flash at 160 MHz and accelerating external memory access.

Pinout & Package

STM32U575RGT6Q is housed in a 64-pin LQFP64 (10 × 10 mm) package with exposed thermal pad, optimized for reflow assembly and thermal dissipation in compact industrial modules.

Pin/Terminal	Circuit Role	Design Meaning
VDD, VSS	Core power supply and ground	Supports 1.71–3.6 V operation; decoupling required per datasheet layout guidelines to maintain low-noise core voltage under dynamic load.
VDDA, VSSA	Analog domain power and ground	Independent analog supply pins enable precise ADC/DAC reference stability; must be filtered separately from digital rails.
PA0–PA15, PB0–PB15, etc.	General-purpose I/Os	Up to 136 fast I/Os with interrupt capability; most are 5V-tolerant and support independent supply down to 1.08 V for mixed-voltage interfacing.

BOOT0	Boot mode selection	Configures boot source (system memory, embedded Flash, or SRAM); sampled at power-on reset and must be held stable during startup.
OSC_IN / OSC_OUT	External crystal oscillator interface	Supports 4–50 MHz crystals; used for high-accuracy system clock or USB timing; requires matched trace length and proper load capacitance.
VBAT	Backup domain supply	Provides power to RTC, 32×32-bit backup registers, and 2-KB backup SRAM during main power loss - enables timekeeping and state retention.

Key Features

Feature	Design Value
LPBAM (Low-Power Background Autonomous Mode)	Enables DMA-driven peripheral chains (e.g., ADC → memory → timer → GPIO) to execute without CPU intervention in Stop 2 mode - reduces active time and extends battery life.
FlexPowerControl with SMPS + LDO	Integrated switch-mode power supply supports dynamic voltage scaling between 0.95 V and 1.2 V core voltage, reducing active power by up to 40% vs. LDO-only operation.

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
STM32L562RET6	Same Cortex-M33 + TrustZone core but limited to 512 KB Flash, no SMPS, no UCPD, lower analog performance (12-bit ADC only).	Suitable for cost-sensitive secure IoT nodes without USB-C or high-resolution analog sensing.	Select when budget constraints outweigh need for 2 MB Flash, CAN FD, or USB PD functionality.
NXP LPC55S69JBD100	Arm Cortex-M33 with TrustZone, 640 KB Flash, no SMPS, no integrated UCPD, lacks LPBAM and advanced analog peripherals.	Better suited for audio-centric edge devices using SAI and DSP workloads, not power-constrained sensor nodes.	Prefer when leveraging NXP's MCUXpresso SDK ecosystem and requiring dual-core asymmetric processing (Cortex-M33 + Cortex-M0+).

Compared with STM32L562RET6 and LPC55S69JBD100, the STM32U575RGT6Q delivers superior ultra-low-power autonomy (LPBAM), higher memory density, integrated USB-C PD control, and richer analog subsystem - making it optimal for next-generation secure, battery-operated industrial and medical endpoints where feature integration and energy efficiency are co-prioritized.

FAQ

What is the maximum operating temperature range for STM32U575RGT6Q?

The STM32U575RGT6Q is qualified for industrial operation from –40 °C to +125 °C ambient temperature. This extended range is validated per JEDEC JESD22-A108 and supports deployment in harsh environments such as motor control enclosures, outdoor utility meters, and automotive under-hood telemetry modules without derating.

Does STM32U575RGT6Q support hardware-based secure boot with public-key verification?

Yes. The device implements a hardware root of trust with immutable boot ROM that verifies signed firmware images using ECDSA P-256 before execution. Public keys are stored in the 512-byte OTP area, and signature validation occurs entirely in secure world - preventing rollback, unsigned code execution, or key extraction attacks.

Can the integrated SMPS be used alongside external DC-DC converters?

Yes. The SMPS can be disabled and bypassed via configuration bits, allowing use of external DC-DC supplies. When enabled, it supports seamless on-the-fly switching between SMPS and LDO modes based on load conditions - critical for dynamic power optimization in variable-workload applications like intermittent sensor polling.

Is the 14-bit ADC capable of oversampling at full 2.5-Msps throughput?

No. At 2.5-Msps, the 14-bit ADC operates in standard mode. Hardware oversampling (up to 256×) reduces effective sampling rate proportionally - e.g., 16× oversampling yields 16-bit resolution at ~156 ksps. Oversampling is autonomous in Stop 2 mode, enabling ultra-low-power background acquisition without CPU wake-up.
