Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings

only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating

conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

The CC2538 contains a power on reset (POR) module and a brown out detector (BOD) that prevent the device from operating under

unsafe supply voltage conditions. In the two lowest power modes, PM2 and PM3, the POR is active but the BOD is powered down,

which gives a limited voltage supervision.

If the supply voltage is lowered to below 1.4 V during PM2/PM3, at temperatures of 70°C or higher, and then brought back up to good

operating voltage before active mode is re-entered, registers and RAM contents that are saved in PM2, PM3 may become altered.

Hence, care should be taken in the design of the system power supply to ensure that this does not occur. The voltage can be

periodically supervised accurately by entering active mode, as a BOD reset is triggered if the supply voltage is below approximately

1.7 V.
