Hi
Im looking in the MPU9250 data sheet but i can found the SPI line voltages.
I found for the I2C for the Vil,Vih, and Voh,Vol, but not for SPI.
So could i count for the Vi/oH range for about 0.7*Vdd - Vdd, or something else ? (Vdd will be 3.3V)
And for the Vi/oL 0V-0.3*Vdd ?
I need to know these values, i we have to add some safety ESD/EMI elements between the sensor and the processor, on which can be some voltage drop.
Thanks
