High sleep current when using SleepTimer and Pin Interrupt to wakeup

[Anonymous]

The specification list 1uA sleep current in sleep mode.  In the Known Problems and Solutions documentation, it states that using SleepTimer and Pin Interrupt to wakeup will result in high current.  Can someone provide an estimate of how much current?

Generally when PSoC3 device is put to sleep with RTC running, we have got about 1uA. Since Sleep Timer is similar in terms of what resource it needs in Sleep mode the current consumtion numbers should be same or slightly higher.

   

As far as the using the Pin Interrupt is concerned, the power will be higher.

   

The actual power consumtion during sleep is dependent on several thigns in addition to powering the device peripherals itself. If a Pin is driving a load during active mode and if this is not taken care before entering Sleep mode, it will continue driving; you will prbably see a higher current.

 Ok, that makes more sense.  Of course, any resource used will add more power during.  But the document gave me the impression that there is a bug that causes additional current, which was my concern.

Let us know if you have any current budget and what exactly you are trying to achieve.
