Hello,Community

About i.MX 7Dual Family of Applications Processors Datasheet Table 29. GPIO DC Parameters
The Min value and Max value of the following parameter are defined by the following formula.
High-level output voltage (VOH) Min is 0.8 × OVDD
Low-level output voltage (VOL) Max is 0.2 × OVDD
Test Conditions are IOH = –1.8mA, –3.6mA, –7.2mA, –10.8mA, IOL = 1.8mA, 3.6mA, 7.2mA, 10.8mA.


In reality, it does not carry that much current.
Please tell me VOH (min) and VOL (max) when the current is lower.
Or if I have a current versus voltage graph, I want.

For example, when VOH and VIL conditions of Table 22. GPIO DC Parameters of i.MX 6Solo / 6DualLite Applications Processors for Industrial Products

Hello,

 

   Use i.MX7 IBIS model in order to get current versus voltage curve.
