Note: Some airlines may permit the use of cellular phones while the
aircraft is on the ground and the door is open. Sierra Wireless
modems may be used at this time.

Required connectors
Note: Contact vendors before
choosing your connectors — the
numbers included here are for
reference only. Choose
connectors that are appropriate
to your design.
Whenintegratingthesemodulesintoyourhostdevice,you
needthefollowingconnectortypes:
•RFcablesthatmatewithHiroseU.FLconnectors(model
U.FL#CL331‐0471‐0‐10).Modulesincludeoneortwo

•Industry‐standardmatingconnectorfor52‐pinEDGE—
somemanufacturersincludeTyco,Foxconn,andMolex.For

•Industry‐standardUSIMconnector(MC87xxonly)—the
actualconnectoryouusedependsonhowyourdevice

Note: The Product Specification Document’s pin connection table
describes the internal structure of the module. For example, a Mini
Card standard-compliant host platform provides +3.3Vaux on pin 24,
but this pin is not connected internally on the MC8775V. Thus, the pin
is flagged as ‘No connect’.

yourapplication.
Note: ESD protection is highly recommended for the USIM connector
at the point where the contacts are exposed, and for any other signals
from the host interface that would be subjected to ESD by the user of
the product.
Module power states
Note: The module unit defaults
to the Normal state when
VCC3.3 is first applied in the
absence of W_Disable# control.
Themodulehasfourpowerstates:
•Disconnected
Nopowertothemodule.
•Off
Powertothemodule,butthemoduleispoweredoff.
•Normal
Themoduleisactive.Severalmodesarepossible(Receive,
Transmit,Sleep,Shutdown).

Power Interface
Rev 1.9.1 Feb.09 Proprietary and Confidential 19

•Low power (“airplane mode”)
Themoduleisactive,butRFisdisabled.
Statemachinesareimplementedinthemoduletomonitorthe
powersupplyandoperatingtemperature.
Disconnected state
Note: The difference between
the Disconnected and Off states
is that, in the Off state, the
module is still connected to the
power source and draws minimal
current.
Thisstateoccurswhenthereisnopowertothemodule—the
hostpowersourceisdisconnectedfromthemoduleandall
voltagesassociatedwiththemoduleareat0V.
Whetherthehostdeviceisalsopoweredoffdependsonthe
powerraildesign.Iftheconnectionbetweenthepowerrail
andthemoduleiscontrolledbythehost,thehostcanstay
poweredonandcutthepowertoputthemodemintothe
disconnectedstate.Ifthepowerrailissharedbetweenthehost
deviceandthemodule,thehostispoweredoffwhenthe
moduleispoweredoff.
Off state
Note: The module enters the Off
state if W_Disable# is driven low
and power (Vcc) is applied to the
module, or if the module is in a
powered state and W_Disable#
is driven low for a module-
dependent minimum period. See
State change: Power off / on on
page 23 for details.
Inthisstate,thehostispoweredupandthemoduleis
powereddown(butstillconnectedtothepowersource).
