The device has an integrated ZEROPOWER power-on reset (POR)/power-down reset

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
