COMPANY CONFIDENTIAL 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).
COMPANY CONFIDENTIAL 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.
COMPANY CONFIDENTIAL 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.
COMPANY CONFIDENTIAL 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.
COMPANY CONFIDENTIAL 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.

COMPANY CONFIDENTIAL 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. Foxconn general design for WWAN module with two control signals.
COMPANY CONFIDENTIAL 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.
