Type Description
I
Used by the PMU to power up/power down
the on-chip regulators that supply power to
the WLAN subsystem. This pin may be
internally driven by the apps core even if the
pin is externally connected to GND.
PWR 1.2V core supply for WLAN.
GND AFE ground. Connect to VSSC for ESD.
GND Internal capacitor-less LDO ground. Connect
to VSSC for ESD.
PWR Internal capacitor-less LDO supply.
GND Ground. Connect to VSSC for ESD.
I/O GPIO
GND Internal LNA ground.
GND LOGEN ground. Connect to VSSC for ESD.
GND LOGEN ground. Connect to VSSC for ESD.
GND Ground. Connect to VSSC for ESD
PWR 1.2V supply
GND Connect to VSSC for ESD
PWR PA 3.3V VBAT supply
GND PAD ground. Connect to VSSC for ESD.
PWR PA Driver VBAT supply.
GND Ground. Connect to VSSC for ESD.
PWR 1.2V supply.
I
2.4 GHz WLAN Receiver input.
O
2.4 GHz WLAN PA output.
GND RX 2 GHz ground. Connect to VSSC for ESD.
PWR Synth VDD 3.3V supply.
GND TX ground. Connect to VSSC for ESD.
GND VCO/LOGEN ground. Connect to VSSC for
ESD.
GND XTAL ground. Connect to VSSC for ESD.
I
