We know that STM32 microcontrollers are an organic combination of ST’s peripherals and various Cortex cores from ARM.ST has produced many microcontrollers based on different Cortex-M cores.
I found a comparison table of different Cortex-M core characteristics on the ARM website, and I would like to share it here for those interested to save for reference.
The table below lists a total of 11 types of Cortex-M core characteristics, such as instruction set architecture, support for FPU, support for hardware division, bus type, CoreMark data, and support for TrustZone, etc. 【The images in the article can be zoomed and moved in mobile mode】
The current product line of STM32 microcontrollers based on various Cortex-M cores from ST is shown in the figure below:
