First question asked Welcome!

Hi,the following page https://github.com/Infineon/optiga-trust-m/wiki/Data-and-Key-Store-Overview says about data-retention-after-testing that "this time is the same as the device lifetime defined in the data sheet."

Where can i find this information? Can you give me more details?

If i write a data object like 0xF1D0 once after production, how long is this information retained?

Regards.

Hello @matteofumagalli 

You can find the data sheet here.

Excerpt from the data sheet on lifetime:

Lifetime for Industrial Automation and Infrastructure is 20 years and 15 years for other Application Profiles.

Depending on where you deploy the OPTIGA™ Trust M device as per the above excerpt, the data is reliable for 15-20 years.
