Hi,

These are the data I can read ..

/******************* Device electronic signature ***************/

#define UID_BASE            0x1FFF7A10UL       /*!< Unique device ID register base address */

#define FLASHSIZE_BASE      0x1FFF7A22UL       /*!< FLASH Size register

Is there any other CPU-specific data I can read? for example the F2 ... F4 family etc.

thank you

Hi,

​

Look for DBGMCU_IDCODE in your reference manual.

You can know the part number, core version, core revision.

​

Some MCUs like L4 can also tell you its package size.

 uint32_t idcode = DBGMCU->IDCODE & 0xFFF; // STM32 Model, upper portion has die stepping version

ARM MCU via SCB->CPUID;
