MCXN236 eFuse / OTP information?

[psmitty7373]

Which document for the MCXN236 has information about the size, use, and addressing of the OTP bits?

Thanks!

Hi @psmitty7373 ,

you can also use MCUXpresso Secure Provisioning tool (https://nxp.com/mcuxpresso/secure) to edit the fuses in GUI tool (see OTP configuration window).

For full fuses description, you need to install restricted data package, that can be downloaded on the same page.

Hello @psmitty7373 ,

Thanks for your post.

According to the section "12.5 eFuse definitions " of MCXN236 reference manual, I believe it can be found in the MCX N23x Security Reference Manual. 

The Security Reference Manual is confidential. You need to sign a NDA with our company and apply for the secure document on your own. The marketing department will decide whether to open it for your account.

Hope it can help you.

BRs,

Celeste

Thanks, Celeste! Very helpful info on accessing the MCXN236 security manual. Navigating NDAs can feel like playing Slope Game - constantly overcoming obstacles! Knowing it's through marketing is key. Perhaps a summary for non-NDA folks could be beneficial? Appreciate the direction!
