SAM4S Series [Preliminary]

Figure 5-1.

Single Supply

Note:

Restrictions

For USB, VDDIO needs to be greater than 3.0V.

For ADC, VDDIN needs to be greater than 2.0V.

For DAC, VDDIN needs to be greater than 2.4V.

Figure 5-2.

Core Externally Supplied

Note:

Restrictions

For USB, VDDIO needs to be greater than 3.0V.

For ADC, VDDIN needs to be greater than 2.0V.

For DAC, VDDIN needs to be greater than 2.4V.

Figure 5-3 below provides an example of the powering scheme when using a backup battery.

Since the PIO state is preserved when in backup mode, any free PIO line can be used to switch

off the external regulator by driving the PIO line at low level (PIO is input, pull-up enabled after

backup reset). External wake-up of the system can be from a push button or any signal. See

Section 5.6 “Wake-up Sources” for further details.
