4.2 Recommended Operating Conditions

The following table provides the recommended operating conditions for the ATWINC3400-MR210xA module.

Table 4-2. ATWINC3400-MR210xA Module Recommended Operating Conditions
Symbol	Parameter	Min.	Typ.	Max.	Units
VDDIO	I/O supply voltage ⁽¹⁾	2.7	3.3	3.6	V
VBAT	Battery supply voltage⁽²⁾⁽³⁾	3.0	3.3	4.2	V
—	Operating temperature	-40	—	85	^ºC

Note:

I/O supply voltage is applied to the VDDIO pin.
Battery supply voltage is applied to the VBAT pin.
The ATWINC3400-MR210xA module is functional across this range of voltages; however, optimal RF performance is ensured for VBAT of 3.3V.
