17. System Power Consumption
Note: Values in this data sheet are design goals and are subject to change based on the results of device
characterization.
■ Unless otherwise stated, these values apply for the conditions specified in Table 24: “Recommended Operating Conditions and DC
Characteristics,” on page 58.
17.1 WLAN Current Consumption
The WLAN current consumption measurements are shown in Table 41.
All values in Table 41 are with the Bluetooth core in reset (that is, Bluetooth is off).

a.Vio is specified with all pins idle and not driving any loads.
b.Idle between beacons.
c.Beacon interval = 100 ms; beacon duration = 1.9 ms @ 1Mbps (Integrated Sleep + wakeup + beacon)
d.Beacon interval = 300 ms; beacon duration = 1.9 ms @ 1Mbps (Integrated Sleep + wakeup + beacon)
e.Carrier sense (CCA) when no carrier present.
f.Carrier sense (CS) detect/packet RX.
g.Applicable to all supported rates.
h.Duty Cycle = 100%
i.TX output power is measured at the chip-out side.
j.The items of active modes are measured under the real association/throughput with the wireless AP.
