PSoC 5, 3 & 1 MCU

[MuKa_284621]

Hello,

       

I recently bought a PSoC 5LP test board and I wanted to use it for measuring consumption.

       

I followed the guidelines on how to configure the board for low-power operations, but I have a problem : I wanted Vddd = Vdda using a power supply (instead of the on-board regulators on the kit) and I found that Vddd != Vdda although I linked both pins together.

       

Before I file in a case, i would like to ask the community if any has seen such problem before.

       

My board is a CY8CKIT-050 revision B.

       

Thanks,

If you look at user guide schematics you can figure out the effects

   

of external connections. Some regulators can handle sink current,

   

others cannot, So use the schematic and a DVM to figure out if various

   

sections are toast in the power supply.

 Alright, I'll try to check it out,

       

In any case, has anyone ever altered the kit for low-power applications before? I'd very much like to get some figures for the low-power modes and the alterations made.

       

Thanks all,

This is a discussion on making measurments, and power considerations.
