Wakeup, ONOFF, PMIC_STBY_REQ and PMIC_ON_REQ in i.MXRT1024

[sowmiya_a]

Hi,

We are planning to use MIMXRT1024CAG4B in our design. A 3.3V buck regulator on board will directly source this microcontroller. On the Evalution board, PMIC_ON_REQ enables the 3.3V regulator. Since we are not using PMIC_ON_REQ to enable buck regulator, can we keep Wakeup, ONOFF, PMIC_STBY_REQ and PMIC_ON_REQ as NC?

Hi @sowmiya_a,

Yes, the WAKEUP, ONOFF, PMIC_STBY_REQ and PMIC_ON_REQ can be left unconnected if they are not used.

BR,

Edwin.
