SBC Sleep Mode with Cyclic Wake

The SBC Sleep Mode has the advantage of reducing the current consumption to a

minimum. During this mode the integrated voltage regulator for external supply is turned

off. In case the connected microcontroller needs to get activated periodically, the Cyclic

Wake feature in combination with the SBC Sleep Mode can be activated (see Figure 6).
