    CYBLE-014008-00 Deep Sleep Current

    ville.tiensuu_1549261

      Hello,

         

      I cannot get CYBLE-014008-00 Deep Sleep Current to correct level. Datasheet specifies 1.3 uA current for Deep Sleep Mode.

         

      Here is one setup that I have tested:

         

      -CYBLE-14008-EVAL connected to CY8CKIT-42 BLE Pioneer Board.

         

      -Following application programmed

         
          

      #include <project.h>
      int main(void)
      {
          CySysPmDeepSleep();
          //CySysPmHibernate();
          
      }

         
         

      -CYBLE-14008-EVAL removed from CY8CKIT-42 BLE Pioneer Board.

         

      -Power supplied to CYBLE-14008-EVAL board (J1 pins 23 and 24)

         

      -Current is measured from power supply

         

       

         

      As a result I am getting currents of 1.1 - 1.3 mA

         

      If I comment out CySysPmDeepSleep() and enable CySysPmHibernate() Current goes to specified levels of Hibernate mode.

         

       

         

      I have set debug pins to GPIO-mode from PSOC-Creator. 

         

       

         

      Could somebody help me to get Sleep current to specified level?
