STM32 MCUs all (?) use the following memory map to some degree. There are minor differences so always check the relevant datasheet for the specific MCU being used.
Block Diagram
Memory Map
The most interesting bit is the detail in the lower left corner specifying the two first blocks of memory.
Memory Details
Of these, the most interesting for a new developer are:
- Flash - 0x8000000
This is where you upload your application.
- RAM - 0x20000000
This is where dynamic variables are allocated.
All internal peripherals are controlled through registers - each with a specific address. But if using HAL it is not necessary to know these addresses.
