VDD5 voltage monitoring electrical characteristics
Tj = -40 °C to 150 °C, VDD5 = 4.5 V to 5.5 V, Vps = 4 V to 28 V unless otherwise specified.
All voltages refer to GND. Currents are positive into and negative out of the specified pin.
4.1.4
VDDIO voltage supply
In order to ensure a full compatibility with 5 V and 3.3V MCU peripherals, a pin VDDIO is
dedicated to supply the output buffer of SDO.
The overall current consumption on VDDIO is "IVDDIO".
