SWAS035A â SEPTEMBER 2016 â REVISED FEBRUARY 2017
In the brownout condition, all sections of the device (including the 32-kHz RTC) shut down except for the
Hibernate module, which remains on. The current in this state can reach approximately 400 µA. The
blackout condition is equivalent to a hardware reset event in which all states within the device are lost.
Table 4-1 lists the brownout and blackout voltage levels.

(1) TI recommends using the lowest possible drive strength that is adequate for the applications. This recommendation minimizes the risk of
interference to the WLAN radio and reduces any potential degradation of RF sensitivity and performance. The default drive strength
setting is 6 mA.
