When PCA8565 work at 90~125℃,CPU can't read the true time from PCA8565.But the timer in the PCA8565 is working normally.When the temperature drops below 90℃,PCA8565 return to normal working condition.
The circuit diagram as follow.
All chips and devices can work at 125 ℃.What factors will cause this error?
