STMicroelectronics STM32H563VGT6

Overview

STM32H563VGT6 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), CORDIC/FMAC math accelerators, dual FDCAN, USB Type-C®/PD controller, and Ethernet MAC - deployed in industrial gateways requiring secure firmware updates and real-time connectivity.

For engineers reviewing the STM32H563VGT6 datasheet, STM32H563VGT6 pinout, STM32H563VGT6 application, or STM32H563VGT6 equivalent, key selection criteria include TrustZone-enabled peripheral partitioning, dual-bank flash with read-while-write for OTA updates, SMPS/LDO power architecture, 140 I/Os with 5 V tolerance, and hardware-accelerated cryptographic functions (ECDSA, HASH, RNG).

Technical Context

The STM32H563VGT6 implements Armv8-M mainline security with configurable SAU regions and GTZC-managed memory/peripheral isolation. Its dual DMA controllers offload CPU for concurrent high-bandwidth transfers across FMC, Octo-SPI, and Ethernet interfaces.

It features two independent 12-bit ADCs (5 Msps), dual 12-bit DAC channels, and dedicated analog blocks including VREFBUF, DTS, and temperature sensor - all accessible in secure or non-secure domains per TrustZone configuration. The ART Accelerator includes 8-Kbyte instruction cache and 4-Kbyte data cache to sustain zero-wait-state execution at 250 MHz.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating?

The STM32H563VGT6 operates at up to 250 MHz and delivers 375 DMIPS (Dhrystone 2.1), measured with ART Accelerator enabled and zero-wait-state flash execution. This performance level is sustained across ambient temperatures from –40°C to +105°C under 1.71–3.6 V supply conditions.

Does the device support secure boot and firmware updates out of the box?

Yes - it implements Secure Firmware Installation (SFI) with hardware-accelerated ECDSA signature verification and HASH computation. Boot process enforces signed images via immutable ROM bootloader, and dual-bank flash enables atomic, rollback-safe OTA updates without external supervision.

What power supply options does the STM32H563VGT6 support?

It supports both integrated SMPS (step-down converter) and LDO regulator modes. The SMPS offers higher efficiency (up to 92%) and configurable output (0.8–1.2 V), while the LDO provides lower noise for analog circuits. Both support dynamic voltage scaling synchronized with CPU frequency changes.

How many I/O pins are 5 V tolerant, and what is the minimum supply voltage for I/O operation?

Up to 140 I/Os are 5 V tolerant when VDDIO2 ≥ 2.7 V. I/Os can operate down to 1.08 V with independent supply (VDDIO2), enabling direct interfacing with ultra-low-voltage peripherals such as certain sensors and RF modules without level shifters.
