AM335x B silicon revision 2.1 RTC power consumption

Hello,

due to advisory 1.0.5 the RTC required VDD core to be present, according to the errata sheet, this is fixed in the new silicon revision.

Can you specify the power consumption for VDDS_rtc when the CPU is not running (VDD core not present)?

The data sheet refers to spadbn5 (table 3-10, note1) which is currently not available (http://www.ti.com/lit/an/sprabn5/sprabn5.pdf ->404)

The wiki page does not list them (yet): http://processors.wiki.ti.com/index.php/AM335x_Power_Consumption_Summary#AM335x_Power_Consumption_for_different_use_cases

I confirmed the bad link and submitted a request to our marketing department to fix this issue.

I will ask someone to answer your question tomorrow.

Lo,

The total device power consumption during RTC-Only mode is ~40uW. The AM335x Power Consumption Summary should be updated within 2 weeks to reflect the power data measured on PG2.1.

Hello,

Is the update released ? can you share a link please

I am looking for information aboute power consamption from VBAT during RTC-ONLY mode.

Regards.

I checked with apps team and they are forecasting the wiki will be updated approximately in two weeks with new data based on new die revision "B".

I'd like to refering to the comment from above that posted by Hieu Nguyen on Apr 18 2013 10:21 AM
Is the ~40uW in RTC-ONLY mode is a valid value for die revision "B" ?
Is the ~40uW in RTC-ONLY mode refering to VBAT power consumption ?

your unswar is necessary for our concept design, thanks.
