STMicroelectronics STM32H725AGI6

Overview

STM32H725AGI6 from STMicroelectronics is a high-performance Arm® Cortex®-M7 32-bit microcontroller operating at up to 550 MHz, featuring 1 MB flash with ECC, 564 KB SRAM (all with ECC), dual 16-bit ADCs delivering up to 3.6 MSPS, and integrated FD-CAN, Ethernet MAC, USB 2.0 HS/FS OTG, and Chrom-ART Accelerator - deployed in industrial HMI controllers requiring real-time graphics, deterministic communication, and secure firmware execution.

For engineers reviewing the STM32H725AGI6 datasheet, STM32H725AGI6 pinout, STM32H725AGI6 application, or STM32H725AGI6 equivalent, key selection considerations include its VFQFPN68 package with 68-pin layout, dual-core-ready memory architecture (TCM + system RAM), 3× FD-CAN interfaces for automotive-grade networking, and hardware-accelerated CORDIC/FMAC for motor control math offload.

Technical Context

The STM32H725AGI6 implements a dual-bank Arm Cortex-M7 core with DP-FPU, L1 instruction/data caches (32 KB each), MPU, and 1177 DMIPS performance. Its memory subsystem includes 128 KB data TCM RAM for time-critical variables and up to 256 KB remappable instruction TCM RAM - enabling zero-wait-state execution of safety-critical ISR code.

It integrates three FD-CAN controllers compliant with ISO 11898-1:2015 (CAN FD 2.0 Mbit/s), an Ethernet MAC with DMA, and dual 16-bit ADCs supporting interleaved mode (7.2 MSPS) - all synchronized via a centralized RCC with multiple PLLs (including audio PLL for SAI clocking) and precise sub-second RTC.

Key Specifications

Pinout & Package

STM32H725AGI6 is housed in a 68-pin Very Thin Quad Flat No-lead (VFQFPN68) package, 8 mm × 8 mm, 0.4 mm pitch, with exposed thermal pad. This RoHS-compliant ECOPACK2 package supports high-density PCB layouts and efficient thermal dissipation in fanless industrial enclosures.

FAQ

What is the maximum operating frequency and core type of the STM32H725AGI6?

The STM32H725AGI6 features an Arm Cortex-M7 core with double-precision FPU, rated for operation up to 550 MHz. It achieves 1177 DMIPS (Dhrystone 2.1) at this frequency, supported by 32 KB instruction and 32 KB data L1 caches that enable zero-wait-state execution from flash or external memory. The core includes a memory protection unit (MPU) for RTOS and safety-critical task isolation.

Does the STM32H725AGI6 support hardware encryption or secure boot features?

Yes - the STM32H725AGI6 includes ROP (Read-Out Protection) and PC-ROP (Program Counter Read-Out Protection), tamper detection pins, and a 96-bit unique ID. It supports secure boot from internal flash with hash verification in ROM, though it lacks dedicated AES/SHA accelerators (unlike the H735). Secure firmware updates require software-implemented cryptography or external secure elements.

What are the supported package types and which one corresponds to the STM32H725AGI6?

The STM32H725AGI6 uses the VFQFPN68 package: 68-pin, 8 mm × 8 mm, 0.4 mm pitch, with exposed thermal pad. Other variants in the H725xG family include LQFP100, TFBGA100, WLCSP115, LQFP144, UFBGA169, and UFBGA(176+25), but only the "I6" suffix denotes the VFQFPN68 variant per ST's device marking convention.

Can the STM32H725AGI6 execute code directly from external memory, and what interfaces support this?

Yes - the STM32H725AGI6 supports eXecute-in-Place (XiP) from external memory via two Octo-SPI interfaces, enabling direct code fetch from external flash or PSRAM without copying to internal RAM. It also supports XiP from NOR flash through the Flexible Memory Controller (FMC), allowing scalable memory expansion while maintaining deterministic interrupt latency.
