Comparison of ARM Cortex-M Core Features

We know that STM32 microcontrollers are an organic combination of ST’s peripherals and various ARM Cortex cores. ST has produced many microcontrollers based on different Cortex-M cores. I found a comparison table of different Cortex-M core feature parameters on ARM’s website, and I would like to share it here for those interested to bookmark for future reference. The table below lists a total of 11 types of Cortex-M core feature parameters, such as instruction set architecture, support for FPU, support for hardware division, bus type, CoreMark data, support for TrustZone, etc. 【The image in the text can be zoomed in and moved for viewing on mobile】
