Product details
Overview
STM32H573VIT3Q from STMicroelectronics is a high-security, high-performance Arm® Cortex®-M33 32-bit microcontroller with TrustZone®, FPU, and 250 MHz operation delivering 375 DMIPS. It integrates 2 Mbyte flash with ECC, 640 Kbyte SRAM (including ECC-protected SRAM2/SRAM3), dual AES coprocessors, and on-the-fly Octo-SPI decryption - deployed in secure industrial gateways requiring real-time control, encrypted firmware updates, and hardware-rooted trust.
For engineers reviewing the STM32H573VIT3Q datasheet, STM32H573VIT3Q pinout, STM32H573VIT3Q application, or STM32H573VIT3Q equivalent, key selection criteria include TrustZone-enforced peripheral isolation, SAES/PKA cryptographic acceleration, 24-timer concurrency (including six low-power timers active in Stop mode), and dual DMA controllers supporting deterministic real-time I/O offload.
Technical Context
The device implements Armv8-M mainline security with configurable SAU regions and preconfigured immutable root of trust (ST-iROT), enabling secure boot via unique entry point and HDP-protected secure hide area. Its dual-bank flash supports read-while-write with 100K-cycle data retention per bank, while SRAM3 offers flexible ECC configuration for safety-critical data buffers.
Security co-processing includes DPA-resistant public key accelerator (PKA) and two AES engines - one hardened against side-channel attacks - paired with NIST SP800-90B-compliant TRNG and hardware-unique key (HUK) for secure key derivation. The OTFDEC engine enables authenticated, decrypted execution directly from external Octo-SPI memories without software intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-security MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32H753VIT6 | No TrustZone, no PKA or DPA-resistant AES; higher max clock (480 MHz) but lower security certification (PSA Level 1) | Suitable for non-regulated real-time control where crypto is software-implemented | Select when raw DSP throughput outweighs hardware security requirements. |
| NXP i.MX RT1176AVM8B | Arm Cortex-M7 + M4 dual-core; lacks integrated OTFDEC and SAES but adds GPU and display pipeline | Better suited for HMI-rich edge devices needing GUI rendering over secure boot | Choose when human interface capability and Linux coexistence are prioritized over PSA Level 3 compliance. |
Compared with STM32H573VIT3Q, the STM32H753VIT6 trades hardware security for higher clock speed and larger flash, while the i.MX RT1176AVM8B shifts focus toward multimedia integration at the expense of dedicated cryptographic accelerators and SESIP3 certification - making the H573 optimal for regulated, crypto-intensive embedded systems.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating?
The STM32H573VIT3Q operates at up to 250 MHz and delivers 375 DMIPS (Dhrystone 2.1), measured with ART Accelerator enabled and instruction cache active. This performance is sustained across temperature ranges (-40°C to +125°C) and supply voltages (1.71–3.6 V), verified per DS14121 Rev 5 test conditions.
Does this MCU support secure debug access, and how is it enforced?
Yes - secure debug requires authenticated access via SWD using a challenge-response protocol tied to the device's unique ID and life cycle state. Debug is permanently disabled in "Closed" life cycle mode unless authorized via secure debug token provisioned during manufacturing, preventing unauthorized firmware extraction or modification.
How does the flexible ECC on SRAM3 improve functional safety compliance?
SRAM3 allows per-sector ECC configuration (full/partial/none), enabling allocation of fully protected memory for ASIL-B/C safety-critical variables (e.g., control loop outputs) while reserving unprotected sectors for transient buffers - reducing overhead and simplifying ISO 26262 FMEDA analysis without compromising fault coverage.
Can the Octo-SPI interface execute code directly from external flash, and what security mechanisms apply?
Yes - the Octo-SPI interface supports XIP (execute-in-place) with on-the-fly AES-128/256 decryption using keys derived from the hardware-unique key (HUK). Decryption occurs transparently in hardware; plaintext never appears on the bus, and access is gated by TrustZone permissions - ensuring code confidentiality and integrity without software overhead.
