Reset and supply management
Power supply scheme
The device requires a 1.65 V to 3.6 V operating supply voltage (V

The device has an integrated ZEROPOWER power-on reset (POR)/power-down reset
(PDR). For the device sales types without the “D” option (see
information
device operates between 1.8 and 3.6 V, BOR is always active 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
Five BOR thresholds are available through option bytes, starting from 1.8 V to 3 V. To
reduce the power consumption in Halt mode, it is possible to automatically switch off the
internal reference voltage (and consequently the BOR) in Halt mode. The device remains in
reset state when V

it is not possible to enable BOR through the option bytes.
The device features an embedded programmable voltage detector (PVD) that monitors the
