Description
Embedded Characteristics
The Supply Controller (SUPC) controls the supply voltage of the Core of the system and man-
ages 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
• Generates the Slow Clock SLCK, by Selecting Either the 22-42 kHz Low Power RC Oscillator
• Supports Multiple Wake Up Sources, for Exit from Backup Low Power Mode
