23. Supply Controller (SUPC)
23.1 Description
The Supply Controller (SUPC) controls the supply voltages of the system and manages the Backup mode. In this
mode, current consumption is reduced to a few microamps for backup power retention. Exit from this mode is
possible on multiple wakeup sources. The SUPC also generates the slow clock by selecting either the slow RC
oscillator or the 32.768 kHz crystal oscillator
.
23.2 Embedded Characteristics
• Management of the Core Power Supply VDDCORE and Backup Mode via the Embedded Voltage Regulator
•
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 Slow RC Oscillator or the 32.768 kHz Crystal
Oscillator
• Backup SRAM
• Low-power Tamper Detection on Two Inputs
• Anti-tampering by Immediate Clear of the General-purpose Backup Registers
• Support of Multiple Wakeup Sources for Exit from Backup Mode
– 14 Wakeup Inputs with Programmable Debouncing
– Real-Time Clock Alarm
– Real-Time Timer Alarm
– Supply Monitor Detection on VDDIO, with Programmable Scan Period and Voltage Threshold
