Note1: for pin27 SUSCLK(32KHz) signal, BCM4356 chipset is capable to tolerate 3.3V, but 1.8V input source is
recommended.
Note2: for pin28 WLAN_RFDISABLE signal, it is provided for legacy wireless communications add-in cards.
It allows users to disable the add-in card’s RF radio operation via a system-provided switch in order to meet public safety
regulations or when otherwise desired. The wireless disable signals are active low signals that when asserted (driven low)
by the system shall disable radio operation. All transients resulting from mechanical switches need to be de-bounced by
system circuitry. It is anticipated that in the future the requirement for hardware wireless disable signals will be
deprecated from use in favor of in-band mechanisms. If use SDIO interface, prefer to use pin45 to do software control to
implement enable/disable the WiFi function. Default is 1.8V, and is capable to tolerate 3.3V.
Note3: for pin42 VIO, by default, MUST keep this pin floating or open.
If host platform can provide the external 1.8V power source as module IO voltage input, thus, the LDO inside module can
be removed. It’s just for customized design only
