STMicroelectronics STM32H7 dual-core Arm® Cortex®-M7 and M4 cores

STM32H745/755 and STM32H747/757 devices are based on the high-performance Arm® Cortex®-M7 and Cortex®-M4 32-bit RISC cores. The Cortex®-M7 core operates at up to 480 MHz and the Cortex®-M4 core at up to 240 MHz. Both cores feature a floating-point unit (FPU) which supports Arm® single and double-precision (Cortex®-M7 core) operations and conversions (IEEE 754 compliant), including a full set of DSP instructions and a memory protection unit (MPU) for enhanced application security.
