Hi,

   

i'm using the CY8C4024LQI-S412 controller on a test board. With a simple program (switch a LED on and off in an ISR) i want to test the power consumption of the UC.

   

In deep sleep mode i measure 240µA! How can i reduce the power consumption further?

   

attached you can see the code in main routine, schematic and pin-out:

First of all switch off the debugging by setting the pins to GPIO.

Thanks Bob! That's it! Now it works. Current consumption = 1,8µA
