STMicroelectronics, 32bit 32 bit MCU, STM32 Microcontroller, 250MHz, 2 Mbyte Flash, 176-Pin LQFP

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 (FPU), which supports all the Arm single-precision data-processing instructions and all the data types.

Includes ST state-of-the-art patented technology
4-Kbyte data cache for external memories
Preconfigured immutable root of trust (ST-iROT)
Secure firmware upgrade support with TF-M
Two AES coprocessors including one with DPA resistance
