a. All measurements include VDDIO current. Depending on factors such as the power topology, external PU/PD
resistors, etc., additional leakage current may occur at the board level.
b. Assumes VBAT is directly used for USB 3.3V supply
c. USB interface remains in active mode
d. Beacon Interval = 102.4 ms, DTIM = 1 or 3, Beacon duration = 1 ms @ 1 Mbps = 192 μs PHY header + 808 us
(101 byte) MPDU
e. Chip Tx output power is based on Broadcom reference board measurements and backward calculation from
antenna test port.
