AM4376: RTC power consumption

Part Number: AM4376
Other Parts Discussed in Thread: AM4378, , TPS65218

Hi,

I am trying to find a figure for the RTC current when in RTC-Only mode. I can't seem to find this in the data sheet - can anybody point me in the right direction ?

I am using the AM4376 with the TPS65218 PMIC, as per the AM4378 General Purpose EVM, and am trying to calculate the required coin-cell capacity

Thanks,

Pete Baston.

Hi,

See the table here: processors.wiki.ti.com/.../Processor_SDK_Linux_Kernel_Performance_Guide

Thanks for that, I guess I can work with the 30uW max. A bit disappointed that the data sheet doesn't have this information, though.

Note that this is a maximum value. Real life precise measurements have shown approx. half that (~12-15uW). Anyway, it's better to calculate for worst case.
