STMicroelectronics STM32H573VIT6TR

Overview

STM32H573VIT6TR from STMicroelectronics is a high-security, high-performance Arm® Cortex®-M33 32-bit MCU with TrustZone®, FPU, 250 MHz max clock, 2-Mbyte ECC flash, and 640-Kbyte SRAM. It integrates dual AES coprocessors (one DPA-resistant), PSA Level 3/SESIP3-certified security, Octo-SPI with on-the-fly decryption, and cryptographic accelerators for secure firmware upgrade via TF-M in industrial control and IoT edge nodes.

For engineers reviewing the STM32H573VIT6TR datasheet, STM32H573VIT6TR pinout, STM32H573VIT6TR application, or STM32H573VIT6TR equivalent, key selection criteria include TrustZone-aware peripheral configuration, dual-bank read-while-write flash with 100K-cycle data retention, 1.71–3.6 V supply range with SMPS support, and verified 5 Msps ADC performance in 12-bit mode.

Technical Context

The device implements Armv8-M mainline security with configurable SAU regions and preconfigured immutable root of trust (ST-iROT), enabling hardware-enforced secure boot and runtime isolation. Its dual GPDMA controllers offload CPU during concurrent crypto operations and high-bandwidth peripheral transfers.

ART Accelerator includes 8-Kbyte instruction cache and 4-Kbyte data cache, enabling zero-wait-state execution from flash and external memories. The CORDIC and FMAC coprocessors accelerate trigonometric and filter computations without CPU intervention-critical for real-time motor control and sensor fusion.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating?

The STM32H573VIT6TR operates at up to 250 MHz with an Arm Cortex-M33 core, achieving 375 DMIPS (Dhrystone 2.1). This performance is sustained with zero-wait-state execution from flash thanks to the 8-Kbyte instruction cache (ART Accelerator), and validated across industrial temperature ranges (–40°C to +105°C).

Does this MCU support secure boot with hardware root of trust?

Yes. It features a preconfigured immutable root of trust (ST-iROT) with secure hide protection area (HDP), unique boot entry validation, and hardware-unique key (HUK) generation. Boot firmware is cryptographically verified before execution, and secure debug authentication enforces life cycle state transitions per PSA specifications.

What external memory interfaces are supported, and which include hardware encryption?

The MCU supports Octo-SPI (with on-the-fly decryption), FMC for SRAM/PSRAM/SDRAM/NOR/NAND, and two SD/SDIO/MMC interfaces. Only Octo-SPI has integrated OTFDEC-enabling transparent AES-128/256 decryption of external flash contents during instruction fetch or data read without CPU involvement.

How many ADC channels and what sampling rate does the device support?

It integrates two independent 12-bit ADCs, each supporting up to 5 Msps in 12-bit mode with programmable resolution down to 6-bit. Both ADCs feature hardware oversampling, analog watchdogs, and DMA-triggered continuous conversion-validated per DS14121 Rev 5 Section 5.3.23 for full-scale linearity and offset error across temperature.
