Note 1: WL_RST_N = Low, VDDIO is not present
Note 2: WL_RST_N = Low, VDDIO is present
Note 3: Carrier Sense (CCA) when no carrier present
Note 4: Carrier Sense (CS) detect/Packet Rx
Note 5: Intra-beacon Sleep
Note 6: Beacon Interval = 102.4 ms, DTIM = 1, Beacon duration = 1 ms @1 Mbps.
Integrated Sleep + wakeup + Beacon Rx current over 1 DTIM interval.
Note 7: CCK power at chip port. Duty cycle is 100%. Includes PA contribution at 3.6V.
Note 8: OFDM power at chip port. Duty cycle is 100%. Includes PA contribution at 3.6V.
Note 9: In WLAN power-saving mode, the following blocks are powered down: Crystal oscillator, Baseband PLL,
AFE, RF PLL, Radio
Note 10: OFDM power at chip port is 16 dBm, duty cycle is 100%, includes PA contribution at 3.6V.
The above blocks are turned ON in the required order with sufficient time for them to settle. This sequencing is
done by the PMU controller that controls the settling time for each of the blocks. It also has information to
determine the order in which the blocks should be turned ON. The settling times and the dependency order
are programmable in the PMU controller. The default CLK settling time is set to 8 ms at power-up. It can be
reduced after power-up.
Note 11: Absolute junction temperature limits maintained through active thermal monitoring and dynamic Tx duty
cycle limiting.
