8 Specifications
All measurements are references of the module pins, unless otherwise indicated. All specifications are over
process and voltage, unless otherwise indicated.
8.1 Absolute Maximum Ratings
These specifications indicate levels where permanent damage to the module can occur. Functional operation is not ensured
under these conditions. Operation at absolute maximum conditions for extended periods can adversely affect long-term
reliability of the module

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

JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
8.3 Recommended Operating Conditions
Function operation is not ensured outside this limit, and operation outside this limit for extended periods can adversely affect
long-term reliability of the module

(1)
When operating at an ambient temperature of over 75°C, the transmit duty cycle must remain below 50% to avoid the auto-protect
feature of the power amplifier. If the auto-protect feature triggers, the device takes a maximum of 60 seconds to restart the
transmission.
(2)
To ensure WLAN performance, ripple on the 2.3-V to 3.6-V supply must be less than ±300 mV.
(3)
The minimum voltage specified includes the ripple on the supply voltage and all other transient dips. The brownout condition is 2.1 V,
and care must be taken when operating at the minimum specified voltage.
