15.2 Overview

The Supply Controller (SUPC) manages the voltage reference and power supply of the device. The SUPC controls the voltage regulators for the core (VDDCORE) domain and adjusts the voltage regulators according to the sleep modes or user configuration.

The SUPC includes two brown-out detectors: BODVDD and BODVDDIO2. BODVDD monitors the voltage applied to the device (VDD), and BODVDDIO2 monitors the internal voltage of the V_DDIO2 domain. BODVDD can monitor the supply voltage either continuously (Continuous mode) or periodically (Sampling mode).

The output supply level of the main voltage regulator is automatically determined by the sleep mode selected in the Power Manager.
