9.2 Recommended Operating Conditions
The following table provides the recommended operating conditions for the ATWILC3000A.
| Characteristic | Symbol | Min. | Typ. | Max. | Units |
|---|---|---|---|---|---|
| I/O Supply Voltage Low Range | VDDIOL(2) | 1.62 | 1.80 | 2.00 | V |
| I/O Supply Voltage Mid-Range | VDDIOM(2) | 2.00 | 2.50 | 3.00 | |
| I/O Supply Voltage High Range | VDDIOH(2) | 3.00 | 3.30 | 3.60 | |
| Battery Supply Voltage | VBAT | 2.5(3) | 3.30 | 4.20 | |
| Operating Temperature | — | -40 | — | 85 | ºC |
Note:
- Battery supply voltage is applied to the VBAT pin.
- I/O supply voltage is applied to the VDDIO pin.
- The ATWILC3000A is functional across this range of voltages; however, optimal RF performance is assured for VBAT in the range ≥ 3.0V VBAT ≤ 4.2V.
