Values in this guide are summarized from the product specification documents (PSDs) - the PSD takes precedence.

Note: ESD protection is highly recommended for the USIM / RUIM

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).

•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0V.

Device-generated RF

Note: The module can cause

interference with other devices

such as hearing aids and on-

board speakers.

Wireless devices such as the

Mini Card transmit in bursts

(pulse transients) for set

durations (RF burst frequencies).

Hearing aids and speakers

convert these burst frequencies

into audible frequencies,

resulting in audible noise.
