DA14580 rise/fall time

The table 267 in the DA14580 documentation lists various DC characteristics about the IOs what I'm missing is the min/max/avg rise/fall time for the GPIOs (or SPI, ... if they differ) to know what maximum frequencies to expect

Device:

Hi marss,

The data requested are not available on the datasheet, performed a few measurements from our hw enginners got the following:

"When measuring the rise and fall time with a 14pF probe on the 3V rail the timing is about 3ns, but this is tightly related to the load seen by the GPIO".

Thanks MT_dialog
