Brownout and Blackout Conditions

The device enters a brownout condition when the input voltage dips below VBROWNOUT (see Figure 8-4 and Figure 8-5). This condition must be considered during design of the power supply routing, especially if operating from a battery. High-current operations, such as a TX packet or any external activity (not necessarily related directly to networking) can cause a drop in the supply voltage, potentially triggering a brownout condition. The resistance includes the internal resistance of the battery, contact resistance of the battery holder (four contacts for a 2× AA battery), and the wiring and PCB routing resistance.

Note:

When the device is in the Hibernate state, brownout is not detected; only blackout is in effect during the Hibernate state.

In the brownout condition, all sections of the CC3135MOD (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 8-1 lists the brownout and blackout voltage levels.
