Dear All,
Can you please elaborate on the S32K322 GPIO - Pad type/Category Maximum switching frequency
GPIO - Super Slow
GPIO - Slow
GPIO - Medium
GPIO - Fast
And where can we find more details ?.
Solved! Go to Solution.
you can find these info in S32K3xxDS:S32K3xx MCU Family - Data Sheet
https://www.nxp.com/docs/en/data-sheet/S32K3xx.pdf
1.Table 24. GPIO DC electrical specifications, 3.3V Range (2.97V - 3.63V)
2.Table 25. GPIO DC electrical specifications, 5.0V (4.5V - 5.5V)
I am looking for the below kind of information.

But in s32K322 IOMUX Excel sheets it is classified as below
Super slow, slow, medium and fast. Where can we find more information on this .
Hi@harish_crowdnid
super slow,slow,medium and fast here refer to GPIO-Standard,Standard plus,Medium and Fast.
ok. Thanks a bunch
