(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.

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.

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.

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.

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.

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..

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.

1.4.10 Antenna Control
T77W595 provides GPIO control signals for external antenna tuner application. The function
is under development for customization. ANTCTRL (0-3) are provided to allow for the
implementation of antenna tuning solutions. The number antenna control lines required will
depend on the application and antenna/band requirements.

coexistence solutions between the radio(s) on the M.2 Card and other off-card radio(s).
These other radios can be located on another M.2 Card located in the same host platform or
as alternate radio implementations (for example, using a PCI Express M.2 CEM or a
proprietary form-factor add-in solution).

1.4.12 RESET#
Asynchronous RESET# pin, active low. Whenever this pin is active, the modem will
immediately be placed in a Power On reset condition. Care should be taken not to activate
this pin unless there is a critical failure and all other methods of regaining control and/or
communication with the WWAN sub-system have failed.
The Reset# signal is relatively sensitive, it is recommended to install one capacitor
(10~100pF) near to the M.2 card pin.

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

visible to the USB and the host, while others are internal to the USB device.

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.

Goals of the solution
In Windows 7, host sends SET_CONFIGURATION request with value 1 to MDM9625
device. 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.
