Supply Controller (SUPC)
The Supply Controller (SUPC) controls the supply voltages of the system and manages the backup low-power
mode. In this mode, current consumption is reduced to a few microamps for backup power retention. Exit from this
mode is possible on multiple wake-up sources. The SUPC also generates the slow clock by selecting either the
low-power RC oscillator or the low-power crystal oscillator.

Embedded Characteristics
Manages the Core Power Supply VDDCORE and the Backup Low-Power Mode by Controlling the
Embedded Voltage Regulator
A Supply Monitor Detection on VDDIO or a Brownout Detection on VDDCORE Triggers a Core Reset
Generates the Slow Clock SLCK by Selecting Either the 22-42 kHz Low-Power RC Oscillator or the 32 kHz
Low-Power Crystal Oscillator
Low-power Tamper Detection on Two Inputs
Anti-tampering by Immediate Clear of the General-purpose Backup Registers
Supports Multiple Wake-up Sources for Exit from Backup Low-power Mode
