COMPANY CONFIDENTIAL 14 1.4 Platform connection design 1.4.1 Configuration Pins The M.2 module provides 4 configuration pins. T77W595 is configured as WWAN-SSIC 0, refer to PCIe M.2_Rev 1.0. Item Module configuration decodes Module type Port configuration Config Config_0 Config_1 Config_2 Config_3 WWAN-SSIC 0 Pin No. 21 69 75 1 State NC GND GND GND 1.4.2 Power and ground (1) Power Rail Parameters Parameter Min Type Max Units Operating voltage 3.135 3.3 4.4 Vdc The operating voltage was defined in PCIe M.2_Rev 1.0 standard as 3.135V~4.4V. (2) 3.135 V is the minimum voltage supplied to LTE M.2 card by the host platform, and VCC must never be under 3.135 V in any case. As our experiment, if we set the VCC=3.0V, the M.2 card will power off when M.2 card working at +23dBm continue mode. (3) Whenever the M.2 module works at 2G mode, the module transmits at the maximum power (like +33dBm), the transient peak current may reach to 2.5 A. We recommended design the VCC supply of host as below: Remark: When the system power restarts, reserve R1 to discharge power. (4) The LTE M.2 module provides 5 power pins and 11 Ground pins. To ensure that the LTE module works normally, all the pins must be connected.
COMPANY CONFIDENTIAL 15 1.4.3 Full_Card_Power_Off The M.2 LTE module can be controlled to power on/off by the Full_Card_Power_Of pin. Item State M.2 card state 1 Low Powers off, It’s internally pulled down by 100K ohm resistor 2 High Powers on, it is 3.3V tolerant but can be driven by either 1.8V or 3.3V GPIO. The recommended connections as below 1.4.4 USB interface T77W595 module is compliant with USB2.0 in all three modes (Low speed, Full speed, and high speed). When two devices are connected via a USB interface, one of the devices must act as a host, and the other device must act as a peripheral. The host is responsible for initiating and controlling traffic on the bus. Figure 1-4-4 USB2.0 interface
COMPANY CONFIDENTIAL 16 1.4.5 W_DISABLE# This control setting is implementation-specific and represents the collective intention of the host software to manage radio operation. T77W595 provides a hardware pin (W_DISABLE#) to disable or enable the radio. Besides, the radio can also be enabled or disabled through software AT commands. Item State Function (WWAN state) W_DISABLE#1 Low WWAN Disabled (no RF operation allowed) High WWAN Enabled (RF operation allowed), internally pull up W_DISABLE#2 Low GPS Disabled (no RF operation allowed) High GPS Enabled (RF operation allowed), internally pull up 1.4.6 LED Indication The LED signal is provided to enable wireless communication add-in cards to provide status indications to users via system provided indicators (1) State of the LED# pin Item State Definition Interpretation 1 Low The LED is emitting light. Radio is capable of transmitting. 2 High The LED is emitting no light. Radio is incapable of transmitting. (2) Typical LED Connection in Platform/System .
COMPANY CONFIDENTIAL 17 1.4.7 WoWWAN The WAKE_ON_WWAN# signal is for power saving. •LTE module always listening at very low power in idle mode •LTE module will wake up mother board via ‘WoWWAN’ signal. •The platform will power on when triggered by the LTE module. The WAKE_ON_WWAN# signal is used to wake up the host. It is open drain and should be pulled up at the host side. When the WWAN needs to wake up the host, it will output a one second low pulse, shown in Figure 1-4-6. Typical Connection in Platform/System
COMPANY CONFIDENTIAL 18 1.4.8 DPR (Dynamic Power Reduction) The optional DPR signal is used by wireless devices to assist in meeting regulatory SAR (Specific Absorption Rate) requirements for RF exposure. The signal is provided by a host system proximity sensor to the wireless device to provide an input trigger causing a reduction in the radio transmit output power. The required value of the power reduction will vary between different host systems and is left to the host platform OEM and card vendor to determine, along with the specific implementation details. The assertion and de-assertion of DPR is asynchronous to any system clock. All transients resulting from the proximity sensor need to be de-bounced by system circuitry. (1) State of the DPR Item State Definition Interpretation 1 Low Enable the SAR power back off. Radio is capable of transmitting. 2 High Disable the SAR power back off, internally pull up Radio is incapable of transmitting. (2) Typical Connection in Platform/System Remark: a. The proximity sensor was controlled by the platform side. b. After DPR pin becomes low level, you can set the MAX TX power by AT commands..
COMPANY CONFIDENTIAL 19 1.4.9 USIM The UIM contains parameters necessary for the WWAN device’s operation in a wireless wide area network radio environment. The UIM signals are described in the following paragraphs for M.2 add-in cards that support the off-card UIM interface. (1) USIM card socket It is recommended to take electrostatic discharge (ESD) protection measures near the USIM card socket. The USIM socket should be placed near the NGFF interface (<100 mm), because a long circuit may impact signal quality. (2) UIM-PWR UIM_PWR power supply can supply 1.8 V and 2.85 V power to UIM card and auto detects follow SIM card type (3) SIM Detect This signal is used to detect the insertion and removal of a SIM device in the SIM socket. With a Normal Short SIM Card connector, PUSH-PUSH type, the detect switch is normally shorted to ground when no SIM card is inserted. When the SIM is inserted, the SIM_DETECT will transition from logic 0 to logic 1 state. The rising edge will indicate insertion of the SIM card. When the SIM is pulled out, the SIM_DETECT will transition from logic1 to logic 0. This falling edge will indicates the pulling out of the SIM card. The M.2 module monitoring this signal will treat the rising/falling edge or the actual logic state as an interrupt, that when triggered, the module will act accordingly.

COMPANY CONFIDENTIAL 33 6. Software Features 6.1 USB Enumeration When a USB device is attached to or removed from the USB, the host uses a process known as bus enumeration to identify and manage the device state changes necessary. When a USB device is attached to a powered port, the following actions are taken: 1. The hub to which the USB device is now attached informs the host of the event via a reply on its status change pipe. At this point, the USB device is in the Powered state and the port to which it is attached is disabled. 2. The host determines the exact nature of the change by querying the hub. 3. Now that the host knows the port to which the new device has been attached, the host then waits for at least 100 ms to allow completion of an insertion process and for power at the device to become stable. The host then issues a port enable and reset command to that port. 4. The hub performs the required reset processing for that port. When the reset signal is released, the port has been enabled. The USB device is now in the Default state and can draw no more than 100 mA from VBUS. All of its registers and state have been reset and it answers to the default address. 5. The host assigns a unique address to the USB device, moving the device to the Address state. 6. Before the USB device receives a unique address, its Default Control Pipe is still accessible via the default address. The host reads the device descriptor to determine what actual maximum data payload size this USB device’s default pipe can use. 7. The host reads the configuration information from the device by reading each configuration zero to n-1, where n is the number of configurations. This process may take several milliseconds to complete. 8. Based on the configuration information and how the USB device will be used, the host assigns a configuration value to the device. The device is now in the Configured state and all of the endpoints in this configuration have taken on their described characteristics. The USB device may now draw the amount of VBUS power described in its descriptor for the selected configuration. From the device’s point of view, it is now ready for use. When the USB device is removed, the hub again sends a notification to the host. Detaching a device disables the port to which it had been attached. Upon receiving the detach notification, the host will update its local topological information. The following diagram and table describe USB device states. Some of these states are

However, because the device is suspended, the host may not use the device's function. 6.2 Windows Morphing The device presents itself as different functions on different Windows OS. On windows 7, its functions include Diag, RmNet, Modem, Application Interface and NEMA after the user installs the driver package. On windows 8.1, its functions are MBIM and GPS after the user installs the driver package. The devices that exhibit morphing behavior are referred to as morphing devices. On Linux, its functions include Diag, ECM, Application Interface, Modem and NMEA. Windows morphing solution maps the morphing device’s USB configuration to a set of USB functions. At any point in time, a single set of functions (by way of a configuration) are exposed to the host. The solution achieves morphing by switching between these configurations. Logical configurations The functions present in the device are grouped into the following logical sets. Table 6-2. Logical Set of Functions Logical Set of Functions Description Windows-7-Configuration Configuration selected by Windows 7 and older versions of Windows when the morphing device is inserted into the host. Linux-Configuration Configuration selected by Linux when the morphing device is inserted into the host. Windows-8-Configuration Configuration selected by Windows 8 when the morphing device is inserted into the host. The following table shows the USB configurations listed in the previous table along with possible interfaces and functions. Additional requirements for each configuration are described in the remaining subtopics. Table 6-2.

The functions defined in Configuration 1 will be exposed to the host.  In Linux, host sends SET_CONFIGURATION request with value 2 to MDM9625 device. The functions defined in Configuration 2 will be exposed to the host  In Windows 8, host sends SET_CONFIGURATION request with value 3 to MDM9625 device. The functions defined in Configuration 3 will be exposed to the host. Configuration requirements The Windows-7-Configuration should be the first configuration in the morphing device. Windows 8 and Linux will not select this configuration. In Windows 7 and earlier versions of Windows, the Windows-7-Configuration is the default configuration selected. The Windows-8-Configuration exposes the MBIM function as one of the functions on which MBCD (Mobile Broadband Class Driver) is loaded. In Windows 8, the value of this configuration is used in the subCompatibleID value returned to USBCCGP. USBCCGP selects this configuration when it is loaded. The Windows-8-Configuration should be either Configuration 2, 3, or 4. No other configuration is supported as the Windows-8-Configuration.

DETACHABLE ANTENNA USAGE This device has been designed to operate with a PIFA antenna have a maximum gain of [6.14] dBi. Antenna having a higher gain is strictly prohibited per regulations of Industry Canada. The required antenna impedance is 50 ohms. Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated
power (e.i.r.p.) is not more than that necessary for successful communication. This radio transmitter (IC: 2878D-T77W595/ Model: T77W595) has been approved by Industry Canada to operate with the antenna type, maximum permissible gain and required antenna impedance for each antenna type indicated. Antenna types not included in this user's manual, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device. Ce dispositif a été conçu pour fonctionner avec une antenne ayant un gain maximal de PIFA antenne avec dBi [6.33]. Une antenne à gain plus élevé est strictement interdite par les règlements d'Industrie Canada. L'impédance d'antenne requise est de 50 ohms. Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peutfonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pourl'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectriqueà l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que lapuissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire àl'établissement d'une communication satisfaisante. Le présent émetteur radio (IC: 2878D-T77W595/ Modèle: T77W595) a été approuvé par Industrie Canada pour fonctionner avec les types d'antenne énumérés ci-dessous et ayant un gain admissible maximal et l'impédance requise pour chaque type d'antenne. Les types d'antenne non inclus dans cette liste, ou dont le gain est supérieur au gain maximal indiqué, sont strictement interdits pour l'exploitation de l'émetteur.
