STMicroelectronics STM32H562AGI6

Overview

STM32H562AGI6 from STMicroelectronics is a high-performance, secure 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 DMA controllers, CORDIC/FMAC math accelerators, and dual FDCAN interfaces. It targets secure industrial control, IoT edge nodes, and smart metering systems requiring real-time processing and firmware integrity.

For engineers reviewing the STM32H562AGI6 datasheet, STM32H562AGI6 pinout, STM32H562AGI6 application, or STM32H562AGI6 equivalent, key selection criteria include TrustZone-enabled secure boot, 250 MHz deterministic execution, dual-bank flash with read-while-write, 140 I/Os (most 5 V-tolerant), and support for USB Type-C®/PD, Ethernet MAC, and Octo-SPI external memory expansion.

Technical Context

The STM32H562AGI6 implements an Armv8-M mainline architecture with hardware-enforced TrustZone isolation, enabling secure and non-secure execution environments. Its dual-cache ART Accelerator includes 8-Kbyte instruction cache and 4-Kbyte data cache, eliminating wait states for flash execution and accelerating external memory access.

It features two independent GPDMA controllers supporting memory-to-memory, peripheral-to-memory, and memory-to-peripheral transfers with FIFO buffering. The security subsystem includes HASH, PKA, ECDSA verification, NIST SP800-90B-compliant TRNG, and active tamper detection-enabling certified secure firmware installation (SFI) and over-the-air updates via TF-M.

Key Specifications

Pinout & Package

The STM32H562AGI6 is housed in a 169-ball UFBGA package (7 × 7 mm, 0.5 mm pitch) with 140 user I/Os, VDD/VSS power pins, dedicated debug (SWD/JTAG), reset (NRST), and multiple voltage domains (VDDA, VREF+, VCAP).

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-security, high-performance MCU applications.

Compared with STM32H562AGI6, the STM32H563AGI6 adds integrated Ethernet PHY and HDMI-CEC at the cost of slightly higher power and reduced SMPS flexibility, while the i.MX RT1189 trades TrustZone peripheral isolation and SFI acceleration for higher single-thread performance and larger on-chip memory-making it less optimal for certified secure firmware lifecycle management.

FAQ

What is the maximum operating temperature range for STM32H562AGI6?

The STM32H562AGI6 is rated for industrial temperature range: –40 °C to +105 °C ambient. This is validated per JEDEC JESD22-A108 and confirmed in Section 5.3.1 of DS14258 Rev 6. Operation beyond this range may cause timing violations or flash write failures due to voltage margin loss.

Does STM32H562AGI6 support external SDRAM, and what interface is used?

Yes, it supports external SDRAM up to 128 MB using the Flexible Memory Controller (FMC) with 16-bit data bus and standard SDRAM command protocol. The FMC also supports LPSDR SDRAM, PSRAM, NOR/NAND, and FRAM-configurable via RCC and FMC registers per RM0481 reference manual.

How many TrustZone-secured peripheral regions can be configured on STM32H562AGI6?

The STM32H562AGI6 implements up to eight configurable SAU (Security Attribution Unit) regions, allowing precise memory and peripheral address ranges to be marked as secure or non-secure. This is documented in Section 3.8 (GTZC) and Section 3.9 of DS14258 Rev 6.

Is the UFBGA169 package of STM32H562AGI6 RoHS and REACH compliant?

Yes, the UFBGA169 package is ECOPACK2 compliant-meeting RoHS Directive 2011/65/EU, REACH Regulation (EC) No. 1907/2006, and halogen-free requirements. Full compliance documentation is available in ST's "Environmental Compliance" database under part number STM32H562AGI6.
