Part Number: AM2732

Hi Experts:

When connecting the AM2732 in CCS,  there are 2 cortex_M4 cores in the debug window.

but these M4 cores are not mentioned in datasheet,

What are the cores intended for? Can them be programmable like  common cores or are they associated with specific usage?

    Hi Ken,

    These M4's are used for HSM functionality. AM273x contains Cortex M4-based Hardware Security Module for running security services in a secure island. 
    You can refer to TRM security addendum for more information on the HSM. This is not released publicly and you need to connect to marketing/sales team.

    Regards,
