STMicroelectronics STM32H573VIT6

Overview

STM32H573VIT6 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 banks), 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 STM32H573VIT6 datasheet, STM32H573VIT6 pinout, STM32H573VIT6 application, or STM32H573VIT6 equivalent, key selection criteria include TrustZone-enforced peripheral isolation, SAES/SAI/FDCAN coexistence for edge-to-cloud connectivity, 1.71–3.6 V supply flexibility, and LQFP100 package compatibility with legacy STM32H7 routing footprints.

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 firmware validation. Its dual DMA controllers offload CPU during concurrent high-bandwidth operations - such as simultaneous FDCAN message handling, SAI audio streaming, and OTFDEC-secured Octo-SPI memory access.

ART Accelerator includes 8-Kbyte instruction cache and 4-Kbyte data cache to sustain zero-wait-state execution at 250 MHz, while CORDIC and FMAC coprocessors accelerate trigonometric and filter computations without CPU intervention - critical for real-time motor control and sensor fusion algorithms.

FAQ

What is the maximum operating frequency and associated performance metric?

The STM32H573VIT6 operates at up to 250 MHz, achieving 375 DMIPS (Dhrystone 2.1) and 1023 CoreMark®. This performance is sustained via the ART Accelerator's 8-Kbyte instruction cache, which eliminates flash wait states - confirmed in DS14121 Rev 5 Section 3.2.1 and Table 7.

Does STM32H573VIT6 support external memory interfaces beyond Octo-SPI?

Yes - it integrates a Flexible Memory Controller (FMC) supporting SRAM, PSRAM, SDRAM/LPSDR, FRAM, and NOR/NAND memories with up to 16-bit data bus width. This is documented in Section 3.21 and electrical characteristics Table 5.3.18 of DS14121 Rev 5.

How is TrustZone implemented for peripheral security?

TrustZone is enforced via the Global TrustZone Controller (GTZC), which configures up to eight SAU regions to assign secure/non-secure attributes to memory and peripherals. All peripherals - including AES, RNG, and OCTOSPI - are TrustZone-aware and require secure-world access permission, per Sections 3.8 and 3.9 of the datasheet.

What packaging options are available for STM32H573VIT6?

The 'VIT6' suffix denotes the LQFP100 (14 × 14 mm) package with ECOPACK2 RoHS compliance. Other variants exist (e.g., 'ZIT6' = LQFP144, 'IIT6' = UFBGA169), but STM32H573VIT6 is exclusively LQFP100 - confirmed in Table 1 and Package Information Section 6.5 of DS14121 Rev 5.
