STM32H742xI/G and STM32H743xI/G devices are based on the high-performance Arm Cortex-M7 32-bit RISC core operating at up to 480 MHz. The Cortex -M7 core features a floating point unit (FPU) which supports Arm double-precision (IEEE 754 compliant) and single-precision data-processing instructions and data types. STM32H742xI/G and STM32H743xI/G devices support a full set of DSP instructions and a memory protection unit (MPU) to enhance application security.
