Power supply supervisor
The device has an integrated power-on reset (POR) and power-down reset (PDR) circuits.
They are always active, and ensure proper operation above a threshold of 2 V. The device
remains in reset mode when the monitored supply voltage is below a specified threshold,
V
●
●
The device features an embedded programmable voltage detector (PVD) that monitors the
V

threshold. The interrupt service routine can then generate a warning message and/or put
the MCU into a safe state. The PVD is enabled by software.
Voltage regulator
The regulator has three operation modes: main (MR), low power (LPR), and power-down.

The voltage regulator is always enabled after reset. It is disabled in Standby mode.

The MR mode is used in the nominal regulation mode (Run)
The LPR mode is used in Stop mode.
The power-down mode is used in Standby mode: the regulator output is in high
impedance, and the kernel circuitry is powered down thus inducing zero consumption.
