UCD9090-Q1: Enable

Part Number: UCD9090-Q1

Hi Team, 

Can we use the PORz_OUT (3.3V) from the AM62 as an input into the UCD to let it know that AM62 is on and ready for other items to be turned on? 

Is there any issue with this?

Thank you, 

Delaney

  • Hi 

    Yes, if you connect it to a MON, UCD will report 2.5V due to the ADC reference. But you can set the scaling ratio to get 3.3V

    Connecting to a GPI will give either asserted or deasserted

    Regards

    Yihe
