can hit 850 mA during device calibration.
• At wakeup, the WiLink 8 module performs the entire calibration sequence at the center of the 2.4-GHz band.
• Once a link is established, calibration is performed periodically (every 5 minutes) on the specific channel tuned.
• The maximum VBAT value is based on peak calibration consumption with a 30% margin.
