We are developing a board based on the iMX53 Quick Start design.  We are trying to size the battery for the RTC.

Has anyone been able to measure the current on the NVCC_SRTC_POW supply?  

The specs indicate a maximum in mA but we were hoping for something more in the uA range!

I saw this discussion: http://imxcommunity.org/group/imx53quickstartboard/forum/topics/keep-the-realtime-clock-running-on-t...

Any feedback would be most appreciated.
