I'm apologize for late reply for this thread.
Yes, the User Guide you referring is the correct User Guide.
The recommended Vccio for I/O standard 2.5 V is (min 2.375, typical 2.5, max 2.625).
And if you are looking for input voltage, the table 1-17 is correct.
- VIL = minimum -0.3V, maximum 0.7V
- VIH = minimum 1.7V, maximum 3.6V
Thanks
