Table 9-1, Table 9-2, and Table 9-3 list performance parameters along with shutdown and sleep currents.

Table 9-1 WLAN Performance Parameters
WLAN(1) CONDITIONS SPECIFICATION (TYP) UNIT
Maximum TX power, 5 GHz (OFDM6) 6-Mbps OFDM 18 dBm
Maximum TX power, 2.4 GHz (1DSSS) 1-Mbps DSSS 16.5 dBm
Minimum sensitivity, 5 GHz (OFDM6) 6-Mbps OFDM –92.5 dBm
Minimum sensitivity, 2.4GHz (1DSSS) 1-Mbps DSSS –95 dBm
Sleep current Leakage, firmware retained 160 µA
Connected IDLE No traffic IDLE connect 750 µA
RX search 2.4-GHz SISO 20 58 mA
RX current (SISO20) MCS7, 2.4 GHz 69 mA
RX current (SISO20) MCS7, 5 GHz 77 mA
TX current (SISO20) MCS7, 2.4 GHz 238 mA
TX current (SISO20) MCS7, 5 GHz 324 mA
Maximum peak current consumption during calibration(2) 850 mA
(1) System design power scheme must comply with both peak and average TX bursts.
(2) Peak current VBAT 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.
  • After 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.
