Other Parts Discussed in Thread: AM3517


Hello,
I would like to save power on AM3517.
I have a question about "AM3517 Power Estimation Spreadsheed" on wiki.
(http://processors.wiki.ti.com/index.php/AM35x_Power_Estimation_Spreadsheet)

On "Section D: FULL CHIP POWER TALLY" of above URL,
I can choose configuration of power domain.

Could you let me know..
 - What is the detail of Standby of VDD_CORE?

 - Does AM3517 power domain support Standby condtion?

Best regards, RY

    Yes, AM3517 supports low power standby mode. In the standby mode, all modules are properly idled, DDR is in self-refresh and IO pad configuration is optimized for the low power status in the system.  Since AM3517 only supports single core power domain, the core power domain can't be turned off and leakage current from the core power domain exists in the standby mode.

    Just an FYI that might help you get more power out of your system,
    Logic PD released their new Wattson software for the AM3517 EVM today which will help you see actual power consumption across all power rails on the CPU and SOM design.  There is an adapter required to connect to the PC available from this website: http://createnewstuff.webs.com/breakoutboardwattson.htm

    The Logic PD software is available from here: http://www.logicpd.com/wattson
