Hi,
We are using AM2432 in one of our design and wanted to as if we are not using the SERDES, USB and MMC0 interface would it be alright to not connect the power supplies so that we can reduce the power consumption and steady state current on the processor?
The pins I am talking about here are VDDA_0P85_SERDES0, VDDA_0P85_SERDES0_C, VDDA_0P85_USB0, VDDA_1P8_SERDES0, VDDA_1P8_USB0. VDD_DLL_MMC0 and VDD_MMC0?
Hello Dhruvil,
Glad to hear about your AM2432 design-in!
There are specific requirements for some pins when they are unused, this information is described in the Pin Connectivity Requirements table of the device datasheet.
Screenshot provided below for quick reference on pins mentioned regarding SERDES0, USB0, and MMC0. Note that both the signal and power pins have unique requirements that must both be met.
Best Regards,
Zackary Fleenor
