Important Notice
Due to the nature of wireless communications, transmission and reception of data can never be
guaranteed. Data may be delayed, corrupted (i.e., have errors) or be totally lost. Although significant
delays or losses of data are rare when wireless devices such as the Sierra Wireless modem are used
in a normal manner with a well-constructed network, the Sierra Wireless modem should not be used
in situations where failure to transmit or receive data could result in damage of any kind to the user or
any other party, including but not limited to personal injury, death, or loss of property. Sierra Wireless
accepts no responsibility for damages of any kind resulting from delays or errors in data transmitted or
received using the Sierra Wireless modem, or for failure of the Sierra Wireless modem to transmit or
receive such data.
Safety and Hazards
Do not operate the Sierra Wireless modem in areas where cellular modems are not advised without
proper device certifications. These areas include environments where cellular radio can interfere such
as explosive atmospheres, medical equipment, or any other equipment which may be susceptible to
any form of radio interference. The Sierra Wireless modem can transmit signals that could interfere
with this equipment. Do not operate the Sierra Wireless modem in any aircraft, whether the aircraft is
on the ground or in flight. In aircraft, the Sierra Wireless modem MUST BE POWERED OFF. When
operating, the Sierra Wireless modem can transmit signals that could interfere with various onboard
systems.
Note: Some airlines may permit the use of cellular phones while the aircraft is on the ground and the door
is open. Sierra Wireless modems may be used at this time.
The driver or operator of any vehicle should not operate the Sierra Wireless modem while in control of
a vehicle. Doing so will detract from the driver or operator’s control and operation of that vehicle. In
some states and provinces, operating such communications devices while in control of a vehicle is an
offence.

2. Pad Definition
AirPrime HL77xx pads are divided into 2 functional categories.
Core functions and associated pads cover all the mandatory features for M2M connectivity and will be available by default across all CF3 family of
modules. These Core functions are always available and always at the same physical pad locations. A customer platform using only these functions
and associated pads are guaranteed to be forward and/or backward compatible with the next generation of CF3 modules.
Extension functions and associated pads bring additional capabilities to the customer. Whenever an Extension function is available on a module, it
is always at the same pad location.
Other pads marked as “not connected” or “reserved” should not be used.

3.8. Main Serial Link (UART1)
The main serial link (UART1) is used for communication between the AirPrime HL77xx modules and a
PC or host processor. It consists of a flexible 8-wire serial interface that complies with RS-232 interface.
The main serial link (UART1) is an asynchronous serial interface.
The signals used by UART1 are as follows:
TX data (UART1_TX)
RX data (UART1_RX)
Request To Send (UART1_RTS)
Clear To Send (UART1_CTS)
Data Terminal Ready (UART1_DTR)
Data Set Ready (UART1_DSR)
Data Carrier Detect (UART1_DCD)
Ring Indicator (UART1_RI)
Note: Signal names are according to PC view.

Note: UART1_CTS must be left floating or set to level “0 before starting the HL77xx module.
3.9. Power On Signal (PWR_ON_N)
The PWR_ON_N signal is internally connected to the permanent 1.8V supply regulator inside the
AirPrime HL77xx module via a pull-up resistor. Once VBATT is supplied to the module, this 1.8V
supply regulator will be enabled and so the PWR_ON_N signal is by default at high level.
A low-level signal on PWR_ON_N must be provided to switch the AirPrime HL77xx module ON, and the
signal must be kept at low level to keep the module ON.

Note: As PWR_ON_N is internally pulled up with 1MΩ, an open collector or open drain transistor must be
used for ignition.
VGPIO is an output from the module that can be used to check if the module is active.
When VGPIO = 0V, the module is OFF
When VGPIO = 1.8V, the module is ON (it can be in idle, communication or sleep mode)
Note: To power the module off, use AT command AT+CPOF or AT+CPWROFF.
3.10. Reset Signal (RESET_IN_N)
To reset the module, a low-level pulse must be sent on the RESET_IN_N pad for 20ms (TBC). This
action will immediately restart the AirPrime HL77xx module with the PWR_ON_N signal at low level. (If
the PWR_ON_N signal is at high level, the module will be powered off.) As RESET_IN_N is internally
pulled up, an open collector or open drain transistor should be used to control this signal.
Note: As RESET_IN_N is referenced to the VGPIO signal (1kΩ pull-up resistor to VGPIO 1.8V) an open
collector or open drain transistor should be used to control this signal.

3.15. Wake Up Signal (WAKE-UP)
The AirPrime HL77xx modules provide one WAKE-UP signal.
The WAKE-UP signal is used to wake the system up from ultra-low power modes (from OFF or Sleep
modes, FAST_SHUTDOWN, or after a software power off). This signal should be set to high level
(external 1.8V) for at least (TBD) ms until the system is active to wake the module up from these
modes.
The system will not be allowed to go into ultra-low or off mode for as long as this signal is kept high.
By default, the software waits for a high state to wake-up.
Note: The module has an embedded pull-down on this signal. After a power off mode, the only way to
restart the module is to perform a hardware power off then power on if this signal is not used.
Refer to the following table for the pad description of the WAKE-UP interface.

5. Design Guidelines
5.1. Power-Up Sequence
Apply voltage to the VBATT pin for at least 10 ms (TBC) prior to applying a low-level logic to the
PWR_ON_N pin.
Apply a low-level logic to the PWR_ON_N pin (pin 59); within approximately 25ms, VGPIO will appear
to be at 1.8V. Either UART1 or the USB interface could be used to send AT commands. The AT
command interface is available in about 25 seconds (TBC) after PWR_ON_N for either UART or USB.
When using UART, the AT command interface is available after the transition of UART1_CTS from
high to low level.
When using a USB connection, the AirPrime HL77xx module will start communicating with the host
after USB enumeration. The time when AT commands can be sent will depend on the initialization
time on the USB host.
Note: As PWR_ON_N is internally pulled up with 1MΩ, an open collector or open drain transistor must be
used for ignition.
5.2. Module Switch-Off
AT commands AT+CPOF and AT+CPWROFF enables the user to properly switch the AirPrime HL77xx
module off.
5.3. Sleep Mode Management
AT command AT+KSLEEP enables sleep mode configuration; this command can only be used with
serial link UART1.
AT+KSLEEP=0:
The module is active when the DTR signal is active (low electrical level).
When DTR is deactivated (high electrical level), the module enters sleep mode after a while.
On DTR activation (low electrical level), the module wakes up.
AT+KSLEEP=1:
The module determines when it enters sleep mode (when no more tasks are running).
Any character on the serial link wakes the module up. The first character is lost.
AT+KSLEEP=2: The module never enters sleep mode.
Note: The DTR signal must only be set to low-level “0” to wake up from Sleep mode. This pin must be set
to high-level “1” (1.8V) or left floating (internal pull-up) for all other modes.
41110555 Rev 1.0 November 01, 2017 40
Product Technical Specification
Design Guidelines
5.4. Power Supply Design
The AirPrime HL77xx module should not be supplied with voltage over 4.5V even temporarily or
however briefly.
If the system’s main board power supply unit is unstable or if the system’s main board is supplied over
4.5V, even in the case of transient voltage presence on the circuit, the module’s power amplifier may
be severely damaged.
To avoid such issues, add a voltage limiter to the module’s power supply lines so that VBATT and
VBATT_PA signal pads will never receive a voltage surge over 4.5V. The voltage limiter can be as
simple as a Zener diode with decoupling capacitors as shown in the diagram below.

5.7. EMC and ESD Guidelines for USIM1 Card
Decoupling capacitors must be added according to the drawing below, as close as possible to the
UIM1 card connectors on UIM1_CLK, UIM1_RESET, UIM1_VCC, UIM1_DATA and UIM1_DET
signals to avoid EMC issues and to comply with the requirements of ETSI and 3GPP standards
covering the USIM1 electrical interface.

7. FCC Legal Information
The HL7718 and HL7748 modules have been granted modular approval for mobile applications.
Integrators may use the HL7718 or HL7748 modules in their final products without additional FCC
certification if they meet the following conditions. Otherwise, additional FCC approvals must be
obtained.
1. At least 20 cm separation distance between the antenna and the user’s body must be
maintained at all times.
2. To comply with FCC regulations limiting both maximum RF output power and human
exposure to RF radiation, the maximum antenna gain including cable loss in a mobile-only
exposure condition must not exceed:
For HL7718: 2 dBi in Band 13
For HL7748:
9.0 dBi in Band 2
6.0 dBi in Bands 4 and 12
3. The HL7718 and HL7748 modules must not transmit simultaneously with other collocated
radio transmitters within a host device.
4. The RF signal must be routed on the application board using tracks with a 50Ω characteristic
impedance. Basically, the characteristic impedance depends on the dielectric, the track width
and the ground plane spacing. In order to respect this constraint, Sierra Wireless
recommends using MicroStrip or StripLine structure and computing the Tracks width with a
simulation tool (like AppCad shown in the figure below and that is available free of charge at
http://www.agilent.com).
41110555 Rev 1.0 November 01, 2017 50
Product Technical Specification
FCC Legal Information
If a multi-layered PCB is used, the RF path on the board must not cross any signal (digital,
analog or supply).
If necessary, use StripLine structure and route the digital line(s) "outside" the RF structure. An
example of proper routing is shown in the figure below.
Stripline and Coplanar design requires having a correct ground plane at both sides.
Consequently, it is necessary to add some vias along the RF path. It is recommended to use
Stripline design if the RF path is fairly long (more than 3cm), since MicroStrip design is not
shielded. Consequently, the RF signal (when transmitting) may interfere with neighbouring
electronics (AF amplifier, etc.). In the same way, the neighbouring electronics (micro-
controllers, etc.) may degrade the reception performances. The GSM/GPRS connector is
intended to be directly connected to a 50Ω antenna and no matching is needed.
5. A label must be affixed to the outside of the end product into which the HL7718 or HL7748
module is incorporated, with a statement similar to the following:
This device contains FCC ID: <FCC ID as listed in the table below>
Embedded Module
FCC ID
HL7718
N7NHL7718
HL7748
N7NHL7748
6. A user manual with the end product must clearly indicate the operating requirements and
conditions that must be observed to ensure compliance with current FCC RF exposure
guidelines.
The end product with an embedded HL7718 or HL7748 module may also need to pass the FCC Part
15 unintentional emission testing requirements and be properly authorized per FCC Part 15.
Note: If this module is intended for use in a portable device, you are responsible for separate approval to
satisfy the SAR requirements of FCC Part 2.1093.
