The Supply Controller (SUPC) controls the supply voltage of the Core of the system and manages the Backup Low
Power Mode. In this mode, the current consumption is reduced to a few microamps for Backup power retention. Exit from
this mode is possible on multiple wake-up sources including events on WKUP pins, or a Clock alarm. The SUPC also
generates the Slow Clock by selecting either the Low Power RC oscillator or the Low Power Crystal oscillator.



Manages the Core Power Supply VDDCORE and the Backup Low Power Mode by Controlling the Embedded 
Voltage Regulator



Generates the Slow Clock SLCK, by Selecting Either the 22-42 kHz Low Power RC Oscillator or the 32 kHz Low 
Power Crystal Oscillator



Supports Multiple Wake Up Sources, for Exit from Backup Low Power Mode



16 Wake Up Inputs, with Programmable Debouncing



Real Time Clock Alarm



Real Time Timer Alarm



Supply Monitor Detection on VDDIO, with Programmable Scan Period and Voltage Threshold



A Supply Monitor Detection on VDDIO or a Brownout Detection on VDDCORE can Trigger a Core Reset



Embeds: 


