Hello everybody,

im struggling with the same problem for 2 weeks now. Im using LPC1754 MCU to control a low power device. The MCU is having low power consumption (around 100uA) in Deep power down mode, which is ok for me. But i need to use the regular power down to wake up the device using GPIO interrupt. But in this mode the consumption is unreasonably high (25 mA). It is the same for deep sleep (25 mA) and sleep mode (27 mA). I have used the code from the application note from NXP and from KEIL evaluation board. I made sure no pins are draining current and at this point it seems as a software problem. Did anyone face a similar situation?

I would be grateful for some guidelines concerning this problem because i have exhausted all the solutions i could think of.
