Secure Manager Memory Mapping for STM32H5F4 (4 MB Flash)

Hello Team,

I am currently reviewing the Secure Manager memory layout described in UM3254 (Secure Manager for STM32H573xx microcontrollers). The document provides predefined flash memory mappings for STM32H573 devices, including the Large Profile layouts shown in Figure 9 and Figure 10.

 

 

 

 

 

 

 

Our plan is to use STM32H5F4, which provides 4 MB of Flash, and I would like to understand the recommended Secure Manager memory mapping for this device.

 

Could you please help with the following:

Is there a predefined Secure Manager flash layout available for STM32H5F4 (4 MB Flash)?
If available, could you share the corresponding memory map.

Could you point me to the exact documentation, application note, user manual section, or reference project that describes Secure Manager support for STM32H5F4 devices?

If no predefined layout exists, could you provide guidance on how the memory regions should be scaled from the STM32H573 large profile/External Flash profile example to support 4 MB Flash devices?

 

Thank you for your support.

Best Regards,

RJ
