Is possible to deactivate VDDX output on S21ZVL?

[NicoGallo]

I'm curretly using the S12ZVL in an application where the VDDX and VDDA pin are used to power and external sensor. I was wondering if it is possbile to turn on and off the output of this pin using the software. Basically, when the S12ZVL goes to stop mode I want to power off the external sensor. It is possbile?

Hi @NicoGallo,

This is not possible.

When the MCU enters the STOP mode, the VDDX regulator changes from the Full Performace Mode (FPM) to the Reduces Performace Mode, but it is still active.

Please note that in the RPM, the regulator can provide 5mA only.

The MCU has the EVDD1 (PP7) the purpose of which is to supply external devices.

It is controlled as any other GPIO, it can be switched off before the MCU enters the Stop mode.

Regards,

Daniel
