STMicroelectronics STM32H562RGT6TR

Overview

STM32H562RGT6TR from STMicroelectronics is a high-security, high-performance Arm® Cortex®-M33 32-bit microcontroller with TrustZone®, FPU, and 250 MHz operation. 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 hardware security features including ECDSA, HASH, and NIST SP800-90B-compliant TRNG. It targets secure industrial control, IoT edge nodes, and smart metering systems requiring certified firmware integrity and real-time deterministic execution.

For engineers reviewing the STM32H562RGT6TR datasheet, STM32H562RGT6TR pinout, STM32H562RGT6TR application, or STM32H562RGT6TR equivalent, key selection criteria include TrustZone-enforced peripheral isolation, 250 MHz real-time performance with 375 DMIPS, dual-bank flash for seamless OTA updates, integrated SMPS regulator support, and verified 5 V-tolerant GPIO capability across 140 pins.

Technical Context

The STM32H562RGT6TR implements Armv8-M mainline security with configurable SAU regions and GTZC-managed memory/peripheral partitioning. Its dual GPDMA controllers offload CPU during high-bandwidth transfers to Octo-SPI, FMC, or Ethernet MAC, while ART Accelerator's 8-Kbyte instruction cache enables zero-wait-state execution from flash at full 250 MHz.

Security is enforced at silicon level: SFI enables authenticated secure firmware installation, tamper detection triggers active response, and PKA accelerates ECDSA signature verification. The device supports TF-M (Trusted Firmware-M) deployment with flexible life cycle states-Secure, Non-Secure, and Debug-authenticated-enabling field-upgradable trusted boot chains.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating?

The STM32H562RGT6TR operates at up to 250 MHz and delivers 375 DMIPS (Dhrystone 2.1) with its Arm Cortex-M33 core. This performance is sustained across all operating voltages (1.71–3.6 V) and ambient temperatures (–40°C to +125°C), validated per DS14258 Rev 6 Section 5.3.1. The ART Accelerator's instruction cache ensures zero-wait-state execution from embedded flash at full speed.

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

Yes - the STM32H562RGT6TR supports authenticated, rollback-protected OTA updates via its Secure Firmware Installation (SFI) feature and Trusted Firmware-M (TF-M) compatibility. Firmware images must be cryptographically signed (ECDSA P-256) and verified by the on-chip PKA before loading into secure flash, with hash validation performed by the dedicated HASH accelerator.

What are the key differences between STM32H562 and STM32H563 variants?

The STM32H562RGT6TR excludes the Ethernet MAC interface present in the STM32H563RGT6, but shares identical CPU, memory, security engines, analog peripherals, and package options. All other specifications - including 250 MHz operation, 2 Mbyte flash, TrustZone configuration, and SMPS regulator - are functionally identical between the two families per DS14258 Table 2.

Is the LQFP64 package pinout compatible with other STM32H5 series devices?

No - the LQFP64 pinout for STM32H562RGT6TR is unique to this specific variant and not pin-compatible with other STM32H5 packages (e.g., LQFP100 or UFBGA169). Pin assignments are defined in DS14258 Section 4.1 and vary significantly across package types due to differing peripheral routing constraints and power/ground distribution requirements.
