MMPF0100 RESETBMCU impedance.

Hi community,

Our partner have a question about MMPF0100 specification.

To decide the pull-up resistor value, they want to know the impedance of RESETBMCU pin.

You know the voltage level is decided by voltage dividing between pull-up resistor and pin impedance.

For example, if RESETBMCPU impedance = 70k ohm, the pull-up resistor value should be up to 30k ohm for i.MX6.


Certainly, we know the pull-up resistor value on the SABRE board (10.0k ohm) is a solution, but the impedance is required to decide the pull-up value strictly for a custom board that RESETBCMU is connected to not only i.MX6 but also other chip.


Would you let me know it?



Best Regards,
