MCX N947 IFR MAP

stejen — Tue, 18 Nov 2025 11:16:55 GMT

Hello, in the reference manual of the MCX N947 is stated:

For all details related to CMPA and CFPA, including their fields and address settings, see the IFR map file MCXNx4x_PFR_Fusemap.xlsx, attached to this document.

However, I can not find that document anywhere. It is not inside the reference manual and not downloadble anywhere either.

I would like to learn more and have a reference of all the CMPA/CFPA fields and their meanings. But I can not find a comprehensive list for my MCU.

Any help would be appreciated,

Thanks

Hi @stejen

you can download Secure Provisioning Tool, that allows to edit the CMPA/CFPA fields. The tool provides simple description for each value. The tool also allows to create bin file from the configuration and/or apply the configuration to chip.

The tool can be downloaded from https://nxp.com/mcuxpresso/secure

Hi @stejen,

Thanks for your post,

The MCXNx4x_IFR_Fusemap.xlsx is attached to the MCX Nx4x Security Reference Manual, apologies the confusion.

A recommendation is to use pdf reader like acrobat reader to see the attached files.
