The STMicroelectronics High performance microcontrollers of the STM32H5 series, based on the high performance Arm Cortex-M33 32 bit RISC core. They operate at a frequency of up to 250 MHz. The Cortex-M33 core features a single precision floating point unit, which supports all the Arm single precision data-processing instructions and all the data types. Low power consumption
Two dual port DMAs with FIFO
Embedded regulator with configurable scalable output to supply the digital circuitry
Arm TrustZone with Armv8-M mainline security extension
