The STMicroelectronics STM32H733xG devices are based on the high-performance Arm Cortex -M7 32-bit RISC core operating at up to 550 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. The Cortex -M7 core includes 32 Kbytes of instruction cache and 32 Kbytes of data cache. STM32H733xG devices support a full set of DSP instructions and a memory protection unit (MPU) to enhance application security.
