can ripple mixed in power pin cause mcu(kl15z128) resets? and how many is the threshold of ripple voltage?
best regards for everyone
The data sheet to the devices give the lowest operating voltage and I would expect that if any power supply ripple stays above that things would be OK.
In case you have resets that "may" be caused due to this, read the RCM_SRS0 register after a reset to see whether it was due to a "power on reset" or "low voltage detector" or possibly another reason.
Hi, Bao De
What is your ripple range? 0.5V? Do you enable LVD function? If yes, please check which LVD level you selected. As you know, VLVW4H max. value is 3.08V. Waiting for your response. Thanks
