Hi,

I am using MK70FN1M0VMJ12 in my project and using 32.768KHz Crystal, 12 MHz Crystal and 50 MHz Oscillator. So want to know if there is any limitation on Jitter or allowable jiiter for MK70FN1M0VMJ12

Secondaly want to what is the minimum/ maximum Rise time and fall time for RESET_b signals

Kindly reply soon

Thanks and Regards,

Hi,

There without any jitter limitation for MK70FN1M0VMJ12 system oscillator or RTC oscillator module.

The external input clock with below requirement:

If you consider to use RESET_b pin to reset the chip, there with the minimum pulse width that is guaranteed to be recognized as a pin interrupt request.

The Min. external reset pulse width is 100ns.

There with no rise time limitation for reset_b signal.

Wish it helps.
best regards
Ma Hui
