PSOC 4 049-42xx Battery Power

[Anonymous]

Hello all,

   

I'm somewhat new to the PSOC 4 and am looking to get it working powered from a battery. I've read the kit manual, and it said that the 049-42xx can be powered with 1.8-5V from a regulated supply connected to VDD. Is this really correct? Also, how well regulated does the source have to be? Could I just connect 2 AA batteries to it with no other regulation? Thanks!

Yes you can run from 2 cells directly w/o a regulator. There are

   

many considerations that determine weather or not to do this,

   

Like do you have an interface to other external logic (regulator needed),

   

using Vdd as a reference for the A/D (regulator needed unless doing ratio

   

metric measurements with A/D)......

       

If you are debugging/programming the part generally speaking you would need

   

regulated supplies. That can be handled with jumpers/diode steering power

   

switching.
