My board has a CY8C4247LQI-BL493 and when I try to increase the power supply from the working 2.5V to 5V at about 4V the power increase rapidly triggering the current limit in the bench power supply that is set to 200mA, at 2.5V it use only 30mA

   

​I tried to set VDDA,VDDD,VDDR to 5V and uncheck Variable VDDA in PSoC Creator without any change

   

I used MiniProg3 as programmer and tried also with CYC8KIT-042-BLE

   

​Programming at 3.3V I get "Detected SiliconID: "FF FF 19 9E" is not in database " message 

   

Programming at 2,5V I Get "Automatically Detected Device: CY8C4247LQI-BL493" and it succeeded

   

Any suggestion to have the board running at 5V as it was designed to work?

Problem solved,

   

the board has mistakenly connected VCCD to VDDD instead VCCD need only a capacitor to GND.

   

That is true if power is between 1.9V to 5V

Hi,

   

Did you change the voltage level in the programmer settings?
