POWER SUPPLY PINS OF PSoC3

[Anonymous]

 hi..

   

      I am using CY8C3866AXI-040 chip of PSOC for my project....till now i worked on its development kit....but now i am planning to remove the chip from development kit and plan to mount it on the PCB which i am going to design.....but the problem is i am  unable to understand the amount of voltage have to give through its VDD pins...

   

Can any one please say...whats the amount of voltage is sufficient to make my chip work without get damaged...

   

I mean...whats the voltage have to give through the pins

   

VDDD, VDDA, VDDio0, VDDio1, VDDio2, VDDio3, VCCa, VCCd......and how can we identify it?

   

If i give +5V to all the above mentioned pins, does it create any problem?

   

Note: In My project, All the peripherals that are needed to interface to PSoC3 are working with +5V and all are digital...

       

Thank you.

Here is a link to the datasheet. In the electrical specs section

   

are all the limits and recommended operating conditions.

This post might help you.  While designing,make sure that Vdda is the highest voltage in the system.

Take a look at this Application Note : AN61290 - PSoC® 3 and PSoC 5LP Hardware Design Considerations

Also look at DVK manuals for example practices in board layout and design.

   

In fact the PCB design files are available for these as well.

       

This is one example - http://www.cypress.com/?rID=37464

       

Also these may help -
