STM32H747/757系列集成了工作频率高达480 MHz的Cortex-M7内核（具有双精度浮点单元）与工作频率高达240 MHz的Cortex-M4内核（具有单精度浮点单元）的性能，与STM32F7系列相比，动态功耗（运行模式）降低一半。
性能
在Cortex-M7的480 MHz fCPU 以及Cortex-M4的240 MHz频率下，从Flash存储器执行时，STM32H7475/757系列能够提供3220 CoreMark /1327 DMIPS的性能，并且利用其L1缓存和ART实现零等待状态。DSP指令和双精度FPU扩大了产品的应用范围。得益于Cortex-M7上的L1缓存（16 KB+16 KB I缓存和D缓存）与Cortex-M4上的ART（自适应实时加速器），可以使用外部存储器而没有性能损失。
安全性
可以使用安全固件安装和安全启动 – 安全固件更新（2019年第3季度推出）以安全的方式执行器件的初始编程，或者执行安全的现场代码升级。这些服务仅适用于嵌入加密/哈希模块的STM32H757器件。
高能效：
多功耗域架构可在低功耗模式设置不同的功耗域，优化功耗效率。除了在运行和停止模式期间用主稳压器和SMPS特性电压调整为不同电压范围的内核供电，设备还内置有USB稳压器来为嵌入式物理层（PHY）供电，以及一个备份稳压器。
- 在运行模式（外设关）和SMPS，典型为145 µ/MHz @VDD = 3.3 V和25 °C
- 2.80 µA待机模式的典型电流（低功耗模式）
图形
支持双层的新型LCD-TFT 充分利用了Chrom‑ART Accelerator™的优势。该图形加速器的内容创建速度是单核的两倍。除了高效的2-D原始数据复制以外，Chrom-ART加速器还支持其他功能，比如图像格式转换或图像混合（定义水平的透明度混合）。这样，Chrom-ART加速器就提高了图形内容创建速度，为其余程序节省了MCU内核处理带宽。此外，STM32H747/757系列内置有一个JPEG硬件加速器，可进行快速JPEG编码和解码，这能够减轻CPU负荷，让它能处理其它任务。
STM32H7x7系列还内置一个MIPI-DSI接口，用于驱动移动电话和手持设备中常见的DSI显示技术。
集成
