(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.

(1) The TX duty cycle (power amplifier ON time) is assumed to be 10% of the device POH. Of the remaining 90% of the time, the device
can be in any other state.

(1) Operating temperature is limited by crystal frequency variation.
(2) 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.
(3) To ensure WLAN performance, ripple on the supply must be less than ±300 mV.
(4) The minimum voltage specified includes the ripple on the supply voltage and all other transient dips. The brownout condition is also 2.1
V, and care must be taken when operating at the minimum specified voltage.
(5) To ensure WLAN performance, ripple on the 1.85-V supply must be less than 2% (±40 mV).
(6) TI recommends keeping VBAT above 1.85 V. For lower voltages, use a boost converter.
