System Controller and Peripheral Mapping
Power-on-Reset, Brownout and Supply Monitor
Power-on-Reset
Brownout Detector on VDDCORE
Supply Monitor on VDDIO
Refer to
All the peripherals are in the bit band region and are mapped in the bit band alias region.
The SAM4S embeds three features to monitor, warn and/or reset the chip:
• Power-on-Reset on VDDIO
• Brownout Detector on VDDCORE
• Supply Monitor on VDDIO
The Power-on-Reset monitors VDDIO. It is always activated and monitors voltage at start up but
also during power down. If VDDIO goes below the threshold voltage, the entire chip is reset. For
more information, refer to the Electrical Characteristics section of the datasheet.
The Brownout Detector monitors VDDCORE. It is active by default. It can be deactivated by soft-
ware through the Supply Controller (SUPC_MR). It is especially recommended to disable it
during low-power modes such as wait or sleep modes.
If VDDCORE goes below the threshold voltage, the reset of the core is asserted. For more infor-
mation, refer to the Supply Controller (SUPC) and Electrical Characteristics sections of the
datasheet.
The Supply Monitor monitors VDDIO. It is not active by default. It can be activated by software
and is fully programmable with 16 steps for the threshold (between 1.6V to 3.4V). It is controlled
by the Supply Controller (SUPC). A sample mode is possible. It allows to divide the supply mon-
itor power consumption by a factor of up to 2048. For more information, refer to the SUPC and
Electrical Characteristics sections of the datasheet.
