Kinetis KL05 internal oscillator precision

Hello,

 

I couldn't find in the datasheet or in the manual the precision of the internal oscillator. In other Microcontrollers it ranges from 0.9% to 3% from what I've seen. Does anyone know the precision of the Kinetis L series internal oscillator?

 

I need to know to decide whether I should use an external crystal or not for UART communication.

 

Thanks.
