性能
- 在280 MHz的CPU频率下，从Flash执行程序时，STM32H742系列能够提供1414 CoreMark /599 DMIPS的性能，利用其L1缓存并实现了零等待执行。
- L1缓存（16 KB的I-缓存 +16 KB的D-缓存）提高外部存储器的执行性能。
安全性
STM32H7B3 MCU包含以下额外安全特性：
- 加密/哈希硬件加速
- 在Octo-SPI外部串行闪存上实时解密
- STM32H755还支持安全固件安装（SFI）嵌入式安全服务，可在执行初始程序时执行安全验证并保护软件IP。
- 安全启动和安全固件升级（SBSFU）
高能效
- 多电源域架构可实现将各电源域配置为低功耗模式，进而优化功耗效率。
- 内置SMPS，用于降低电源电压。还可用于为外部电路供电，以及特定应用情况下结合LDO共同使用。
- 在内核运行模式（外设外设关）和SMPS情况下，典型功耗为120 µA/MHz @VDD = 3.3 V和25 °C
- 低功耗停止模式下的典型功耗电流为32 µA
- 低功耗待机模式下的典型功耗电流为2.2 µA
- 带RTC的VBAT模式（低功耗模式）下通常为0.74 µA
图形
- LCD-TFT控制器接口支持双层图形
- Chrom-ART Accelerator™提高了图形内容创建速度，并为其它应用节省了MCU内核处理带宽
- Chrom-GRC™优化RAM使用
- JPEG硬件加速器，可进行快速JPEG编码和解码，从而减轻CPU编解码负荷
