Linux/AM3358: RTC accuracy

Stefan Blattmann

Part Number: AM3358

Tool/software: Linux

Hello ti community,

 

I want to use the internal rtc from the am3358 in a Linux System. In our application, we need a lot of time stamps for some data in a database. The application sync the System over an ntp request, but our system can’t request for every timestamp the ntp. My question is about the free running time and the accuracy from the internal rtc of the am3358. Is there any documentation about the accuracy from the rtc used with the internal 32 kHz clock over time and temperature?

 

thanks

Steven
