AIROC™ Bluetooth® LE module
Module connections
HOST_WAKE 36 BT_HOST_WAKE O VDDO Host wake-up. This is a signal from
the Bluetooth® device to the host
indicating that the Bluetooth®
device requires attention.
• Asserted: Host device must wake
up or remain awake
• Deasserted: Host device may
sleep when sleep awake criteria
is met. The polarity of this signal
is software configurable and can
be asserted high or low.
NA NA BT_RF I/O PAVDD2P5 RF antenna port
NA NA JTAG_SEL – – ARM JTAG debug mode control:
connect to GND for all applications
XRES 3 RST_N I VDDO Active-low system reset with
open-drain output and internal
pull-up resistor

Description
Notes
4. The CYBLE-3x307x-02 contains a single SPI (SPI1) peripheral supporting both master or slave configura-
tions. SPI2 is used for on-module serial memory interface.
5. In Master mode, any available GPIO can be configured as SPI1_CS. This function is not explicitly shown in
Table 20.
