Dear sir,
In MCXA153 datasheet, the Port rise/fall time for medium I/O pins is like below.
But I measure the Pin GPIO3_6 real rise time, the time value is 45.2ns. It is more slower then spec.
Could you please give me some suggestion?
Thanks.

Sean Wu.

Hi,
Pls refer to the test condition under which the GPIO pin(The GPIO pin is configured in output mode ) toggles and is tested the rising/falling time.
The pin parasitic capacitance is required to be 25pF when the GPIO output pin toggles, so I suggest you select a GPIO pin, the GPIO pad(LQFP package) is not connected out, then test it with scope.
Hope it can help you
