Tom,

Please check the App Note: TMS320DM368 Power Consumption Summary (SPRABB4) which is available from the device Product Folder: http://www.ti.com/product/tms320dm368. There is a spreadsheet which allows you to estimate device power consumption under a number of different use cases. There is support for PRTCSS in this analysis.

Regards.

I have the App Note and Spreadsheet. The power for PRTCSS is blank (0 mW).

Tom,

Here are the power numbers you were requesting:

Voltage (V)          Power (uW)
=======================
1.2V (core)            91.2
1.8V (IO)                79.2

Power measurements made at 25 degC

Regards.

Hi,

we are using the TPS65510 to power the RTC circuit of the DM368 and we have enabled the RTC. After powering off the board we measure 28,8uA of current drain from the Battery.

Is this correct? is there any way to lower the power consumtion of the RTC of the DM368 ?

Thanks

Sandro
