Sleep mode

[marvelous]

Hi guys,

I wonder something:

Does any circuit with PIC consume power while in sleep mode (assuming i used sleep mode in coding my PIC)?

For the sake of simplicity, assume i have a circuit with a button and when i do not push the button for 10 minutes, the circuit goes to sleep mode until i push the button again. It then wakes up.

So, if i use sleep mode, would it let me get rid of any power on/off button from my circuit?

Thanks.

Yes, but you have to make sure you design your circuit to have minimum power consumption, and also have some way of waking it up - there are MicroChip application notes dealing with this very application. The PIC still uses some current, but it's very low.
