Look at attached file. It is NXP SDK 0.5 Reference Manual. See information about Trustzone in the file.

Have a great day,
Pavel

Hi Pavel,

I had read the datasheet after my post and I am sad because the controller used TZASC380. This controller does not NSAID feature.

It is necessary that I use the TZC400 controller for trustzone protection.

Thanks you very much for your help.

Best regards,

PS: if freescale works on TZC400 and NSAID, I think that is interessant that each CPU have unique NSAID.
