STMicroelectronics STM32H747ZIY6TR

Overview

STM32H747ZIY6TR from STMicroelectronics is a dual-core 32-bit Arm® Cortex®-M7 (480 MHz) + Cortex®-M4 (240 MHz) microcontroller with 2 MB flash, 1 MB RAM (192 KB TCM), and integrated SMPS regulator. It features DSI host, MIPI D-PHY, JPEG codec, and 168 GPIOs - deployed in industrial HMI, medical imaging front-ends, and real-time motor control systems requiring deterministic M7/M4 task partitioning.

For engineers reviewing the STM32H747ZIY6TR datasheet, STM32H747ZIY6TR pinout, STM32H747ZIY6TR application, or STM32H747ZIY6TR equivalent, key selection criteria include dual-core clock domain isolation, SMPS vs LDO supply configuration, DSI interface timing compliance, and TCM RAM allocation for time-critical ISR execution.

Technical Context

The device implements three independent power domains (D1/D2/D3) enabling selective clock gating and voltage scaling across CPU, peripherals, and reset/clock subsystems. Its interconnect matrix comprises one AXI and two AHB bus matrices with five AHB2-APB and two AXI2-AHB bridges, supporting concurrent high-bandwidth data movement between cores and peripherals.

Dual-core operation is coordinated via shared memory with hardware semaphores and interrupt forwarding; the M7 core handles compute-intensive tasks (e.g., JPEG decode, FFT) while the M4 manages real-time I/O (CAN FD, SDMMC, USB OTG) with dedicated DMA controllers including MDMA, dual-port DMAs, and basic DMA with request routing.

FAQ

What is the maximum operating frequency of each core in the STM32H747ZIY6TR?

The Cortex-M7 core operates up to 480 MHz with double-precision FPU and L1 cache (16 KB instruction + 16 KB data), delivering 1027 DMIPS. The Cortex-M4 core runs up to 240 MHz with single-precision FPU and ART Accelerator, achieving 300 DMIPS. Both frequencies are achievable simultaneously under SMPS-supplied VCORE at 1.35 V with full voltage scaling enabled.

Does the STM32H747ZIY6TR support hardware JPEG encoding and decoding?

Yes - it integrates a dedicated hardware JPEG codec capable of encoding and decoding JPEG images up to 4096×4096 pixels. Encoding a 640×480 RGB24 frame takes <8 ms; decoding the same frame requires <6 ms. The engine operates independently of both CPU cores and uses its own DMA channel to access memory.

How does the SMPS regulator function in the STM32H747ZIY6TR?

The integrated SMPS step-down converter supplies VCORE (1.0–1.35 V) directly from VDD (1.62–3.6 V). It supports six voltage scaling ranges and dynamic switching between SMPS and LDO modes. External components include two 2.2 µF VCAP capacitors and optional external compensation network for stability across load transients up to 200 mA.

What display interfaces are supported by the STM32H747ZIY6TR?

The device supports MIPI DSI host with integrated D-PHY (up to 500 Mbps/lane), LCD-TFT controller (XGA resolution), and Chrom-ART DMA2D accelerator. It drives displays via 1/2/3/4-lane DSI configurations with programmable lane swap and automatic LP-to-HS transition. No external level shifters are needed for DSI signaling.
