AM437x schematic checklist

Michi Yama
Guru 10030 points


Hi,

I have questions regarding the handling of AM437x unused pins.

I check "AM437x Schematic Checklist" of Wiki page. The below is my questin.

1) > If ADC0/1 are not used... : Connect all TSC_ADC terminals (VREFP, VREFN, AIN[7:0], VDDA_ADC, and VSSA_ADC) to same ground as all VSS terminals.

    In this case, RXACTIVE should be  to "0" ( Recieve disabled)?

2) For RTC pins, there is a table of RTC mode in Wiki page.

     If RTC feature disabled, each RTC pin should be connected to specified terminal based on the table.  For example, CAP_VDD_RTC should be connected to VDD_CORE. Is my understanding right?

Please advise me.

I appreciate your quick reply.

Best regards,

Michi
