STMicroelectronics STM32H747BGT6

Overview

STM32H747BGT6 from STMicroelectronics is a dual-core 32-bit Arm® Cortex®-M7 (up to 480 MHz) and Cortex®-M4 (up to 240 MHz) microcontroller with double-precision FPU, 2 MB flash, 1 MB RAM (including 192 KB TCM), and integrated SMPS regulator. It supports DSI display interface, Ethernet MAC, dual CAN FD, and hardware JPEG codec - deployed in industrial HMI, medical imaging front-ends, and real-time motor control systems.

For engineers reviewing the STM32H747BGT6 datasheet, STM32H747BGT6 pinout, STM32H747BGT6 application, or STM32H747BGT6 equivalent, key selection factors include dual-core asymmetric execution capability, on-chip SMPS power architecture, DSI host + LTDC graphics pipeline, and deterministic low-latency peripheral routing via AXI/AHB interconnect matrix.

Technical Context

The device implements a true heterogeneous dual-core architecture: the M7 core handles high-throughput tasks (e.g., image processing, protocol stacks) with L1 cache (16 KB I-Cache + 16 KB D-Cache) and 1027 DMIPS performance, while the M4 core manages real-time control loops and sensor fusion with ART Accelerator for zero-wait-state flash execution. Both cores operate independently with separate memory maps and privilege domains.

Its power architecture features three isolated voltage domains (D1/D2/D3), an embedded SMPS step-down converter (supporting direct VCORE supply), and dynamic voltage scaling across six ranges - enabling sub-3 µA standby current (RTC/LSE active, Backup SRAM off) and precise energy budgeting per subsystem.

Key Specifications

Pinout & Package

STM32H747BGT6 is housed in a 169-ball UFBGA package (7 × 7 mm, 0.65 mm pitch), compliant with ECOPACK2 environmental standards. Pin functions are defined across five voltage domains (VDD/VSS, VDDA/VSSA, VREF+/VREF–, VCAP, VBAT) and support multiple alternate functions per pin via flexible remapping.

FAQ

What is the maximum operating frequency of each core in the STM32H747BGT6?

The Cortex-M7 core runs at up to 480 MHz with double-precision FPU and L1 cache enabled, delivering 1027 DMIPS; the Cortex-M4 core operates at up to 240 MHz with single-precision FPU and ART Accelerator, achieving 300 DMIPS. Both frequencies are validated under full voltage scaling range 1 (Vcore = 1.32 V) and ambient temperature ≤85°C per DS12930 Rev 3 Section 6.3.14.

Does the STM32H747BGT6 support hardware JPEG encoding and decoding?

Yes - it integrates a dedicated hardware JPEG codec capable of real-time encoding and decoding of YUV422 and RGB565 formats up to 1024×768 resolution. The codec operates independently of both CPU cores, uses DMA for memory transfers, and supports quantization table customization per application requirement as specified in Section 3.27 of the datasheet.

How many power domains does the STM32H747BGT6 have, and what do they control?

The device implements three independent power domains: D1 (high-performance domain hosting Cortex-M7, AXI bus, and GPU-related peripherals), D2 (communication and timer domain with Cortex-M4, USB, CAN, Ethernet), and D3 (low-power domain containing reset/clock/power management logic and RTC). Each domain supports individual clock gating and power switching per Section 3.5.1.

What display interfaces are supported natively without external bridge ICs?

The STM32H747BGT6 natively supports MIPI DSI via its integrated D-PHY physical layer and LCD-TFT controller (LTDC) for direct connection to DSI-compatible panels up to XGA resolution. It also supports parallel RGB (via LTDC) and 8-/16-bit Intel 8080/6800 bus interfaces. No external bridge IC is needed for DSI or RGB output - only passive termination and timing-critical layout adherence per Section 3.26.
