Power supply supervisor
The power supply supervisor is enabled by holding PDR_ON high.
The device has an integrated power-on reset (POR) / power-down reset (PDR) circuitry
coupled with a Brownout reset (BOR) circuitry. At power-on, BOR is always active, and
ensures proper operation starting from 1.8 V. After the 1.8 V BOR threshold level is reached,
the option byte loading process starts, either to confirm or modify default thresholds, or to
disable BOR permanently. Three BOR thresholds are available through option bytes.
The device remains in reset mode when V

The device also features an embedded programmable voltage detector (PVD) that monitors

message and/or put the MCU into a safe state. The PVD is enabled by software.
All packages, except the LQFP64, offer the internal reset is controlled through the PDR_ON
signal.
Voltage regulator

Regulator ON/internal reset ON
The regulator ON/internal reset ON mode is always enabled on LQFP64 package.
On LQFP100 and LQFP144 packages, this mode is activated by setting PDR_ON to
V
On UFBGA176 package, the internal regulator must be activated by connecting
BYPASS_REG to V
On LQFP176 packages, the internal reset must be activated by connecting PDR_ON to
