VBAT and VIO | 2.3 | 3.3 | 3.6 | V |
Operating temperature | –20 | 25 | 70 | °C |
Ambient thermal slew | –20 | | 20 | °C/minute |
(1) Operating temperature is limited by crystal frequency variation.
(2) To ensure WLAN performance, the ripple on the power supply must be less than ±300 mV. The ripple should not cause the supply to fall below the brown-out voltage.
