STMicroelectronics STM32H747AGI6

Overview

STM32H747AGI6 from STMicroelectronics is a dual-core 32-bit Arm® Cortex®-M7 (up to 480 MHz) and Cortex®-M4 (up to 240 MHz) microcontroller with 2 MB flash, 1 MB RAM, integrated SMPS regulator, MIPI DSI host, and hardware JPEG codec. It supports real-time deterministic control and high-throughput multimedia processing in space-constrained industrial HMI and edge AI inference nodes.

For engineers reviewing the STM32H747AGI6 datasheet, STM32H747AGI6 pinout, STM32H747AGI6 application, or STM32H747AGI6 equivalent, key selection criteria include dual-core asymmetric execution capability, on-chip SMPS for power efficiency, DSI interface for embedded display subsystems, and hardware-accelerated JPEG encoding/decoding for vision preprocessing.

Technical Context

The device implements a heterogeneous dual-core architecture where the M7 core handles high-performance tasks (e.g., real-time control loops, DSP algorithms) with double-precision FPU and 32 KB L1 cache, while the M4 core manages communication stacks, peripheral offloading, and low-latency I/O handling using ART Accelerator for zero-wait-state flash execution.

Its interconnect matrix comprises one AXI and two AHB bus matrices with five AHB2-APB bridges and two AXI2-AHB bridges, enabling concurrent high-bandwidth data movement across domains - critical for simultaneous camera capture (DCMI), display output (LTDC + DSI), and Ethernet MAC DMA transfers without CPU contention.

FAQ

What is the maximum operating frequency of each core in the STM32H747AGI6?

The Arm Cortex-M7 core operates at up to 480 MHz with double-precision FPU and 32 KB L1 cache, while the Cortex-M4 core runs at up to 240 MHz with single-precision FPU and ART Accelerator. Both cores support independent clock sources and voltage scaling, enabling dynamic performance/power trade-offs during runtime.

Does the STM32H747AGI6 support hardware-accelerated cryptography?

No, the STM32H747AGI6 does not include dedicated cryptographic accelerators such as AES, SHA, or PKA engines. It provides ROP and PC-ROP for basic code protection and tamper detection, but full cryptographic operations must be implemented in software or via external secure elements.

Can the STM32H747AGI6 drive an RGB LCD panel directly without external components?

Yes - the integrated LCD-TFT controller (LTDC) supports parallel RGB interfaces up to XGA resolution (1024×768) with up to 24-bit color depth and hardware layer blending. It requires only passive termination resistors and timing-matched trace routing; no external display bridge or level shifters are needed for standard RGB panels.

How many power domains does the STM32H747AGI6 have, and what do they control?

The device has three independent power domains: D1 (high-performance, hosts M7 core and AXI bus), D2 (communication peripherals and timers), and D3 (reset/clock/power management). Each can be clock-gated or powered down individually, enabling granular power optimization - for example, keeping D3 active for RTC while shutting down D1/D2 in standby mode.
