Electrical characteristics
4.9.2
The device implements a power-on reset (POR) module to ensure correct power-up initialization, as well as four low voltage
detectors (LVDs) to monitor the V

This capacitance value is driven by the constraints of the external voltage regulator supplying the V
A typical value is in the range of 470 nF.
This value is acceptable to guarantee operation from 4.5 V to 5.5 V.
External regulator and capacitance circuitry must be capable of providing I
in operating range.
In-rush current is seen only for short time during power-up and on standby exit (max 20 µs, depending on external
capacitances to be load).
POR monitors V
LVDHV3 monitors V
LVDHV5 monitors V
LVDLVCOR monitors power domain No. 1
LVDLVBKP monitors power domain No. 0
Voltage monitor electrical characteristics
When enabled, power domain No. 2 is monitored through LVD_DIGBKP.
