STMicroelectronics STM32H563ZGT6

Overview

STM32H563ZGT6 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 STM32H563ZGT6 datasheet, STM32H563ZGT6 pinout, STM32H563ZGT6 application, or STM32H563ZGT6 equivalent, key selection criteria include TrustZone-enforced peripheral isolation, dual-bank read-while-write flash for OTA updates, SMPS/LDO power architecture, 140 GPIOs (most 5 V-tolerant), and hardware-accelerated crypto (HASH, PKA, ECDSA) for secure boot and firmware installation.

Technical Context

The STM32H563ZGT6 implements Armv8-M security extensions via TrustZone®, enabling strict separation of secure/non-secure execution states with up to eight configurable SAU regions. Its dual GPDMA controllers offload CPU-intensive data movement across peripherals including Octo-SPI, FMC, and Ethernet MAC.

It features two independent cache subsystems: an 8-Kbyte instruction cache (ICACHE) enabling zero-wait-state execution from flash or external memory, and a 4-Kbyte data cache (DCACHE) optimized for external memory access. The ART Accelerator tightly couples with both caches to sustain 250 MHz core performance under real-world code density.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating?

The STM32H563ZGT6 operates at up to 250 MHz and delivers 375 DMIPS (Dhrystone 2.1), measured with the ART Accelerator enabled and zero-wait-state execution from flash. This performance is sustained across temperature and voltage ranges per DS14258 Rev 6 Section 5.3.1.

Does this MCU support secure over-the-air (OTA) firmware updates?

Yes - it supports Secure Firmware Installation (SFI) using hardware-accelerated ECDSA signature verification and PKA, combined with TrustZone-enforced secure boot flow. OTA updates are validated before execution, with rollback protection enforced via dual-bank flash and immutable root-of-trust.

What power supply options does the STM32H563ZGT6 support?

It supports both integrated LDO and external SMPS step-down converter configurations. The SMPS output is configurable (0.8–1.4 V) to supply the digital core, reducing system power by up to 30% versus LDO-only operation - detailed in DS14258 Rev 6 Section 3.10.1 and Table 5.3.3.

How many communication interfaces are available for industrial networking?

The device provides two FDCAN interfaces compliant with ISO 11898-1:2015, one Ethernet MAC with DMA, one USB Type-C®/PD controller (UCPD), and up to twelve UART/LPUART channels - enabling simultaneous CAN bus monitoring, wired Ethernet backhaul, USB-C device charging/control, and legacy serial protocol bridging.
