OMAP l137 EVM power question

PJD

I was wondering whether someone has some power measurements for the OMAP l137 EVM board they would be willing to share. I'd be interested in the power draw when processors are basically idle as well as some point or two of reference for the power draw when the processors are doing something. Obviously I'm just looking for ballpark numbers, so saying something like xW measured at 5V input for doing xyz would be great.

Many Thanks in Advance,

Mariana,

Thanks for the pointer. Some useful info, though I don't think there is any information about the EVM board consumption there. I'm looking for power draw at the 5V board supply of the EVM, not just the OMAP l137 itself. Unless I'm missing something on that page.

Regards,

PJD,

The full power consumption information for the chip is not ready yet. As for the power consumption for the EVM, I do not have it. Maybe someone in the community can help.

Running idle my OMAPL137 EVM is taking about 300mA @ 5V and with some active reading a writing on the SPI ports I go up to about 400mA @5V. Be aware there are a lot of other components active on the board other than the DSP itself.

Nkeddem,

Thanks, that's exactly the numbers I'm looking for. I'm considering using the EVM itself for a rush prototype that has to be in a sealed box. I need to do some quick calculations to figure out how tough the thermal issues are going to be.

Does anyone have any power measurement with the DSP and ethernet doing something close to capacity including off chip memory accesses.

Thanks to all.
