Hi everyone!

I have a hard time finding the tolerance / accuracy for the internal oscillator for the MachXO2. I seem to remember it being around 5%, which isn't really that great.
Can anyone point me in the direction where that's definitively mentioned?!

It's even slightly worse than 5%:

The MachXO2 device has an internal oscillator that can be used as a  
clock source in a design. The internal oscillator accuracy is +/- 5%  
(nominal). This oscillator is intended as a clock source for  
applications that do not require a higher degree of accuracy in the clock.
