PIN DEFAULT FUNCTION STATE AT RESET I/O TYPE DESCRIPTION
AND HIBERNATE
1 NC Hi-Z N/A Unused; leave unconnected.
2 nHIB Hi-Z I Hibernate signal input to the NWP (active low).
This is connected to the MCU GPIO. If the
GPIO from the MCU can float while the MCU
enters low power, consider adding a pull-up
resistor on the board to avoid floating.
3 Reserved Hi-Z NA Reserved for future use
4 FORCE_AP Hi-Z I For forced AP mode, pull to high on the board
using 100k resistor. Otherwise, pull down to
ground using 100k resistor.

13 FLASH _SPI_MISO Hi-Z I Serial flash interface: SPI data in
(active high)
14 FLASH _SPI_nCS Hi-Z O Serial flash interface: SPI chip select (active
low)
15 HOST_INTR Hi-Z O Interrupt output (active high)
16 NC Hi-Z N/A Unused; leave unconnected.
17 NC Hi-Z N/A Unused; leave unconnected.
18 NC Hi-Z N/A Unused; leave unconnected.
19 Reserved Hi-Z N/A Connect 100K pull-down to ground.
20 NC Hi-Z N/A Unused; leave unconnected.
21 SOP2/TCXO_EN Hi-Z O Enable signal for external TCXO. Add 10k
pulldown to ground.
22 WLAN_XTAL_N Hi-Z Analog Connect the WLAN 40-MHz XTAL here.
23 WLAN_XTAL_P Hi-Z Analog Connect the WLAN 40-MHz XTAL here.

27 NC Hi-Z N/A Unused; leave unconnected.
28 NC Hi-Z N/A Unused; leave unconnected.
29 Reserved Hi-Z O Reserved for future use
30 Reserved Hi-Z O Reserved for future use
31 RF_BG Hi-Z RF 2.4-GHz RF TX/RX
32 nRESET Hi-Z I RESET input for the device. Active low input.
Use RC circuit (100k || 0.1 µF) for power on
reset.
33 VDD_PA_IN Hi-Z Power Power supply for the RF power amplifier (PA)
34 SOP1 Hi-Z N/A Add 100K pulldown to ground.
35 SOP0 Hi-Z N/A Add 100K pulldown to ground.
36 LDO_IN1 Hi-Z Power Input to internal LDO
37 VIN_DCDC_ANA Hi-Z Power Power supply for the DC-DC converter for
analog section
(1) Using a configuration file stored on flash, the vendor can optionally block any possibility of bringing up AP using the FORCE_AP pin.
