In Active halt mode 3v it is consuming 11uA This is fine. As we increase the voltage above 3v the current gradually increasing 3v ------->11uA3.3v------>80uA3.6v------->195uAAs per datasheet in Active halt mode it should consume 0.9uAPlease suggest why it is behaving in this way?How to reduce the current consumption in halt mode for above values.

Question

We are using STM8L052C6T6 . We are facing some issue on current consumptions. Below are the observations.

In Active halt mode 3v it is consuming 11uA This is fine. As we increase the voltage above 3v the current gradually increasing
3v ------->11uA
3.3v------>80uA
3.6v------->195uA

As per datasheet in Active halt mode it should consume 0.9uA

Please suggest why it is behaving in this way?

How to reduce the current consumption in halt mode for above values.

What are the gpio configuration status? They might consume power proportional to voltage.

Thank you for quick response.

All gpio's are open state.

After adding the ADC,UART,TIMER,GPIO's, The current consumption increased to 130uA @3v in active halt mode.

It is consuming 263uA @3.4v.

Please suggest how to reduce the current consumption?
