SIM7906E-PCIE: PCIE_WAKE_N
SIM7906E-PCIEU: WAKE#
SIM7906E-PCIEAU: MIC_P
The WAKE# pin can be used as an interrupt signal to host. Normally it will keep high logic level until certain condition such as receiving SMS, voice call (CSD, video) or URC reporting, then WAKE# will change to low logic level to inform the master (client PC). It will stay low until the master clears the interrupt event with AT command.
Figure 7: WAKE# behaviour
However, if the module is used as caller, the WAKE# will remain high. Please refer to the following figure.

If PCIe or Analog audio is available, wake up function is invalid. Please consult our sales staff for more information.
3.6 USB 2.0
SIM7906E-PCIE is compliant with USB 2.0 specification. It supports full-speed and high- speed when acting as a peripheral device.
3.6.1 USB Application Guide
SIM7906E-PCIE can be used as a USB device. SIM7906E-PCIE supports the USB suspend and resume mechanism which can reduce power consumption. If there is no data transmission on the USB bus,
SIM7906E-PCIE will enter suspend mode automatically, and will be resumed by some events such as voice call or receiving SMS, etc.

SIM7906E-PCIE_Hardware_Design_V1.02
Figure 10: USB Reference Circuit
Because of the high bit rate on USB bus, please pay more attention to the influence of the junction capacitance of the ESD component on USB data lines. Typically, the capacitance should be less than 1pF.
It is recommended to use an ESD protection component such as ESD9L5.0ST5G provided by On
Semiconductor (www.onsemi.com ).
NOTE
1. The USB_DN and USB_DP nets must be traced by 90Ohm+/-10% differential impedance.
2. The SIM7906E-PCIE has two kinds of interface (UART and USB) to connect to host CPU. For example, on windows XP operating system, USB interface is mapped to 4 virtual ports: “SimTech
HS-USB AT Port 9001”, “SimTech HS-USB Audio port 9001”, “SimTech HS-USB Diagnostics
9001”, “SimTech HS-USB NMEA 9001”.
3.7 USIM Interface
SIM7906E-PCIE support both Class B and Class C type SIM card . USIM interface is powered from an internal regulator in the module.

Minimum functionality mode
Function
AT command “AT+CSCLK=1” can be used to set the module to a sleep mode. In this case, the current consumption of module will be reduced to a very low level and the module can still receive paging message and SMS.
Software is active. Module is registered to the network, and the
Module is ready to communicate.
Connection between two subscribers is in progress. In this case, the power consumption depends on network settings such as DTX off/on, FR/EFR/HR, hopping sequences, and antenna.
Module is ready for data transmission, but no data is currently sent or received. In this case, power consumption depends on network settings.
There is data transmission in progress. In this case, power consumption is related to network settings (e.g. power control level); uplink/downlink data rates, etc.
AT command “AT+CFUN=0” can be used to set the Module to a minimum functionality mode without removing the power supply. In this mode, the RF part of the Module will not work and the USIM card will not be accessible, but the serial port and USB port are still accessible. The power consumption in this mode is lower than www.simcom.com

AT command “AT+CFUN=4” or pulling down the W_disable1# pin can be used to set the Module to flight mode without removing the power supply. In this mode, the RF part of the Module will not work, but the serial port and USB port are still accessible. The power consumption in this mode is lower than normal mode.
The Module is no power off in this PCIE design. The only way to power off is cut the PCIE’ power.
5.3.2 Sleep mode
In sleep mode, the current consumption of module will be reduced to the minimal level, and module can still receive paging message and SMS.
Several hardware and software conditions must be satisfied together in order to let SIM7906E-PCIE enter into sleep mode:
1. UART condition
AT command AT+CSCLK can be used to sleep/wakeup mode. (refer to Document [22] for more details.)
AT+CSCLK=0 can set PCIE always work.
AT+CSCLK=1 can set PCIE sleep when DTR pull high and other task is off.
2. USB condition
PCIE sleep method: User AP send AT+CSCLK=1 via USB, and the AP goes to sleep, and then PCIE enter sleep mode.
PCIE Wake method: AP pulled the DTR to high and send AT+CSCLK=0 via USB, then PCIE enter wake mode.
3. Software condition
NOTE
Before designing, pay attention to how to realize sleeping/waking function.
5.3.3 Minimum functionality mode
Minimum functionality mode ceases a majority function of module, thus minimizing the power consumption. This mode is set by the AT command which provides a choice of the functionality levels.

7.4 Safety Caution
Table 37: Safety caution
Marks Requirements
When in a hospital or other health care facility, observe the restrictions about the use of mobiles. Switch the cellular terminal or mobile off, medical equipment may be sensitive to not operate normally for RF energy interference.
Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it is switched off. The operation of wireless appliances in an aircraft is forbidden to prevent interference with communication systems. Forget to think much of these instructions may lead to the flight safety or offend against local legal action, or both.
Do not operate the cellular terminal or mobile in the presence of flammable gases or fumes. Switch off the cellular terminal when you are near petrol stations, fuel depots, chemical plants or where blasting operations are in progress. Operation of any electrical equipment in potentially explosive atmospheres can constitute a safety hazard.
Your cellular terminal or mobile receives and transmits radio frequency energy while switched on. RF interference can occur if it is used close to TV sets, radios, computers or other electric equipment.
Road safety comes first! Do not use a hand-held cellular terminal or mobile when driving a vehicle, unless it is securely mounted in a holder for hands free operation.
Before making a call with a hand-held terminal or mobile, park the vehicle.
GSM cellular terminals or mobiles operate over radio frequency signals and cellular networks and cannot be guaranteed to connect in all conditions, for example no mobile fee or a invalid SIM card. While you are in this condition and need emergent help, please remember using emergency calls. In order to make or receive calls, the cellular terminal or mobile must be switched on and in a service area with adequate cellular signal strength.
Some networks do not allow for emergency call if certain network services or phone features are in use (e.g. lock functions, fixed dialing etc.). You may have to deactivate those features before you can make an emergency call.
Also, some networks require that a valid SIM card be properly inserted in the cellular terminal or mobile.
