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

Hi marss,

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
