Power supply supervisor
The device has an integrated ZEROPOWER power-on reset (POR)/power-down reset
(PDR) that can be coupled with a brownout reset (BOR) circuitry.
For devices operating between 1.8 and 3.6 V, the BOR is always active at power-on and
ensures proper operation starting from 1.8 V. After the 1.8 V BOR threshold is reached, the
option byte loading process starts, either to confirm or modify default thresholds, or to
disable BOR permanently (in which case, the V
BOR thresholds are available through option bytes, starting from 1.8 V to 3 V. To reduce the
power consumption in Stop mode, it is possible to automatically switch off the internal
reference voltage (V
below a specified threshold, V
circuit.
For devices operating between 1.65 V and 3.6 V, the BOR is permanently disabled.
Consequently, the start-up time at power-on can be decreased down to 1ms typically.
The device features an embedded programmable voltage detector (PVD) that monitors the
V
levels between 1.85 V and 3.05 V, chosen by software, with a step around 200 mV. An
interrupt can be generated when V

Voltage regulator
The regulator has three operation modes: main (MR), low power (LPR) and power down.

MR is used in Run mode (nominal regulation)
LPR is used in the Low-power run, Low-power sleep and Stop modes
Power down is used in Standby mode. The regulator output is high impedance, the
kernel circuitry is powered down, inducing zero consumption but the contents of the
registers and RAM are lost are lost except for the standby circuitry (wakeup logic,
