TDA2SX: PRCM power consumption

Daniel Cheng1

Part Number: TDA2SX

Hi Expert,

https://e2e.ti.com/support/processors/f/processors-forum/749362/am5748-power-consumption-spike-on-move-from-am5728-to-am5748

Does it mean that enable or disable PRCM MODULE  will always be consuming leakage power even if they are not clocked?

Is the same power consumption for PMHAL_PRCM_MODULE_MODE_DISABLED and PMHAL_PRCM_MODULE_MODE_AUTO?

Thanks

Daniel

    Hi Daniel,

    The PRCM module handles the device resets, clock, etc. It is always on and I'm not sure why you would want to turn it off..

    without knowing exactly I would say power consumption would be pretty close regardless of the state as this is always ON.

    Thanks,
