Hello,
There is a typo in Table 14 in page 153. It is mentioned in different places that STM32H7B0 supports OTP but in this table it is not mentioned!
Could you please confirm that this variant supports OTP?
Thanks,
Ayoub

Hello @Ayoub Cheggari,
Indeed, it is supported. You can refer to Table 17. Flash memory OTP organization

>>So you confirm that there is a typo in Table 14?
Semantically if the tables are describing different things, probably not..
Do you feel the details conflict or overlap?

Hello @Ayoub Cheggari ,
I can confirm STM32H7B0 supports OTP. However, table 14 is not supposed to cover all the details. Instead, in Table 17. you can refer to the Flash memory OTP organization

Thanks for replying! I am saying this because I usually use tha Table to define what is supported or not. Now it's clear to me that it's supported.
Thanks

Yet it does show the System memory and option bytes regions, which are also "details". And the other reference manuals show these and the OTP region in the overall FLASH memory organization table.
Also the author didn't ask for OTP internal layout table.
Edited to adhere to community guidelines.

Following your request, I have submitted an internal ticket 158923 to include OTP area in Table 14. and Table 15. I hope it will enhance our customers' visibility of information and help them better understand it. Even though it is supported in all products covered in this reference manual.
Thanks
