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 HL8549 and HL8549-G pins are divided into 2 functional categories.
Core functions and associated pins 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 pin locations. A customer platform using only these functions
and associated pins is guaranteed to be forward and/or backward compatible with the next generation of CF3 modules.
Extension functions and associated pins bring additional capabilities to the customer. Whenever an Extension function is available on a module, it
is always at the same pin location.
Other pins marked as “not connected” or “reserved” should not be used.

3.5.1. UIM1_DET
UIM1_DET is used to detect and notify the application about the insertion and removal of a SIM
device in the SIM socket connected to the main SIM interface (UIM1). When a SIM is inserted, the
state of UIM1_DET transitions from logic 0 to logic 1. Inversely, when a SIM is removed, the state of
UIM1_DET transitions from logic 1 to logic 0.
Enabling or disabling this SIM detect feature can be done using the AT+KSIMDET command. For more
information about this command, refer to document [2] AirPrime HL6 and HL8 Series AT Commands
Interface Guide.

3.9. Main Serial Link (UART1)
The main serial link (UART1) is used for communication between the AirPrime HL8549 and
HL8549-G module and a PC or host processor. It consists of a flexible 8-wire serial interface that
complies with RS-232 interface.
The supported baud rates of the UART1 are 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600,
115200, 230400, 460800, 500000, 750000, 921600, 1843200, 3000000, 3250000 and 6000000 bit/s.
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)

3.10. POWER ON Signal (PWR_ON)
A low level signal has to be provided to switch the AirPrime HL8549 and HL8549-G module ON.
It is internally connected to the permanent 1.8V supply regulator inside the HL8549 and HL8549-G via
a pull-up resistor. Once VBAT is supplied to the HL8549 and HL8549-G module, this 1.8V supply
regulator will be enabled and so the PWR_ON signal is by default at high level.
The PWR_ON signal’s characteristics are listed in the table below.

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: PWR_ON cannot be used to power the module off. To power the module off, use AT command
AT+CPOF.
3.11. Reset Signal (RESET)
To reset the module, a low level pulse must be sent on the RESET pin for 10ms. This action will
immediately restart the AirPrime HL8549 and HL8549-G module with the PWR_ON signal at low
level. (If the PWR_ON signal is at high level, the module will be powered off.) As RESET is internally
pulled up, a simple open collector or open drain transistor can be used to control it.
The RESET signal will reset the registers of the CPU and reset the RAM memory as well, for the next
power on.
Note: As RESET is referenced to the VGPIO domain (internally to the module), it is impossible to reset
before the module starts or to try to use RESET as a way to start the module.
Another more costly solution would be to use MOS transistor to switch the power supply off and
restart the power up procedure using the PWR_ON input line.

Two Analog to Digital Converter inputs, ADC0 and ADC1, are provided by the AirPrime HL8549 and
HL8549-G module. These converters are 10-bit resolution ADCs ranging from 0 to 1.2V.
Typically, the ADCx input can be used to monitor external temperature. This is very useful for
monitoring the application temperature and can be used as an indicator to safely power the
application OFF in case of overheating (for Li-Ion batteries).

3.13. PWM
The AirPrime HL8549 and HL8549-G modules provide two PWM signals that can be used in
conjunction with an external transistor for driving a vibrator, or a backlight LED.
Each PWM uses two 7-bit unsigned binary numbers: one for the output period and one for the pulse
width or the duty cycle.
The relative timing for the PWM output is shown in the figure below.

3.15. PCM
The Digital Audio (PCM) Interface allows connectivity with standard audio peripherals. It can be used,
for example, to connect an external audio codec.
The programmability of this interface allows addressing a large range of audio peripherals.
The signals used by the Digital Audio Interface are as follows:
PCM_SYNC: The frame synchronization signal delivers an 8 kHz frequency pulse that
synchronizes the frame data in and the frame data out.
PCM_CLK: The frame bit clock signal controls data transfer with the audio peripheral.
PCM_OUT: The frame “data out” relies on the selected configuration mode.
PCM_IN: The frame “data in” relies on the selected configuration mode.
The PCM interface is a high speed full duplex interface that can be used to send and receive digital
audio data to external audio ICs. The Digital Audio Interface also features the following:
PCM master or slave
16 bits data word length, linear mode
MSB first
Configurable PCM bit clock rate on 256kHz, 384kHz or 512kHz

3.21.3. TX Burst Indicator (2G_TX_ON)
The AirPrime HL8549 and HL8549-G module provides a signal, 2G_TX_ON, for TX Burst indication.
The 2G_TX_ON is a 1.8V signal and its status signal depends on the module transmitter state.
Refer to the following table for the status of the 2G_TX_ON signal depending on the embedded
module’s state.
Table 32. Burst Indicator States
Embedded Module State
2G_TX_ON
During TX burst
High

During TX burst, there is a higher current drain from the VBATT_PA power supply which causes a
voltage drop. This voltage drop from VBATT_PA is a good indication of a high current drain situation
during TX burst.
The blinking frequency is about 217Hz.
The output logic high duration, Tduration, depends on the number of TX slots and is computed as follows:
T duration = T advance + (0.577ms x number of TX slots) + T delay

3.22. GNSS Interface
The AirPrime HL8549-G embeds an integrated and high-sensitivity Global Navigation Satellite System
(GNSS) solution.
Based on SiRFstarV™ from CSR, the HL8549-G combines GPS and GLONASS reception to improve
navigation capabilities and position accuracy in obstructed view environments such as urban canyons.
GNSS performances are improved by CW jammer and interference mitigation system and automated
hardware blanking capabilities.
In addition, it supports Control Plane Assisted GPS and Secure User Plane Location (SUPL) protocol
to reduce the time to first fix in the presence of assistance information from wireless networks.
The operation of GNSS is offloaded to a GNSS standalone solution to guaranty the modem resources
availability for the best performances.
The GNSS implementation supports GPS L1 signal (1575.42 ± 20 MHz) and GLONASS L1 FDMA
signals for frequency -7 to 6 (1597.5 – 1605.8 MHz), with 50Ω connection on RF_GPS pad.

5. Design Guidelines
5.1. Power-Up Sequence
Apply a LOW level logic to the PWR_ON pin (pin 59); within 25ms, VGPIO will appear to be at 1.8V.
Either a USB or UART1 interface could be used to send AT commands. Note that for USB
connections, the time when AT commands can be sent will depend on the initialization time used for
the USB connection with the USB host.
Figure 12. PWR_ON Sequence with VGPIO Information
Note: As PWR_ON is internally pulled up with 200kΩ, a simple open collector or open drain transistor
must be used for ignition.
The PWR_ON pin has the minimum assertion time requirement of 25ms, with LOW active. Once the
valid power on trigger is detected, the PWR_ON pin status can be left open.
VBATT has to ramp up within 32 ms to reach the value of 3.2V; otherwise, the module may not power
up.
Figure 13. PWR_ON Sequence with Trampup
5.2. Module Switch-Off
AT command AT+CPOF enables the user to properly switch the AirPrime HL8549 and HL8549-G
module off. The PWR_ON signal must be set to high (inactive) before the AT+CPOF command is sent.
Note: If the PWR_ON signal is active (low level) when the AT+CPOF command is sent, the module will
not power off.
If required, the module can be switched off by controlling the power supply. This can be used, for
example, when the system freezes and no reset line is connected to the AirPrime HL8549 and
HL8549-G module. In this case, the only way to get control over the module back is to switch off the
power line.

Product Technical Specification
Design Guidelines
Figure 14. Power OFF Sequence for PWR_ON, VGPIO
Note: PWR_ON is internally pulled up by 200kΩ to 1.8V.
5.3. Emergency Power OFF
If required, the module can be switched off by controlling the RESET pin (pin 11). This must only be
used in emergency situations if the system freezes (not responding to AT commands).
To perform an emergency power off, a low level pulse must be sent on the RESET pin for 10ms while
the PWR_ON signal is inactive (high level). This action will immediately shut the HL8549x module
down and the registers of the CPU and RAM memory will be reset for the next power on.
5.4. Sleep Mode Management
5.4.1. Using UART
AT command AT+KSLEEP enables sleep mode configuration.
AT+KSLEEP=0:
The AirPrime HL8549 and HL8549-G module is active when DTR signal is active (low
electrical level).
When DTR is deactivated (high electrical level), the AirPrime HL8549 and HL8549-G module
enters sleep mode after a while.
On DTR activation (low electrical level), the AirPrime HL8549 and HL8549-G module wakes
up.
AT+KSLEEP=1:
The AirPrime HL8549 and HL8549-G module determines when it enters sleep mode (when
no more tasks are running).
“0x00” character on the serial link wakes the AirPrime HL8549 and HL8549-G module up.
AT+KSLEEP=2:
The AirPrime HL8549 and HL8549-G module never enters sleep mode.
4115653 Rev 3.0 July 31, 2014 44

5.4.2. Using USB

The AirPrime HL8549x 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 with
over 4.5V, even in the case of transient voltage presence on the circuit, the HL8549x’s power
amplifier and GPS chipset 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.

5.6. ESD Guidelines for SIM Card
Decoupling capacitors must be added as close as possible to the SIM card connectors on UIM1_CLK,
UIM1_RST, UIM1_VCC and UIM1_DATA signals to avoid EMC issues and to pass the SIM card type
approval tests, according to the drawings below.
A typical schematic for hardware SIM detection is provided below.

5.7. ESD Guidelines for USB
When the USB interface is externally accessible, it is required to have ESD protection on the
USB_VBUS, USB_D+ and USB_D- signals.
Figure 17. ESD Protection for USB
Note: It is not recommended to have an ESD diode with feedback path from USB_VBUS to either
USB_D+ or USB_D-.
5.8. Dual SIM Application
Using an external switch and GPIOs, the HL8549 and HL8549-G can support Dual SIM Single
Standby with fast network switching. Refer to document [2] AirPrime HL6 and HL8 Series AT
Commands Interface Guide for related AT commands.

5.9. Radio Integration
5.9.1. GSM Antenna Integration with Antenna Detection
Circuitry
The AirPrime HL8549 and HL8549-G is equipped with external antennas. A 50Ω line matching circuit
between the module, the customer’s board and the RF antennas is required, for GSM and GPS feed
path, as shown in the example below.
Figure 19. GSM Antenna Connection with Antenna Detection
Note: Antenna detection circuit is optional. Rant is the equivalent DC terminating resistor of the antenna.
Rant should be close to 10KΩ.
5.9.2. GNSS Active Antenna Integration
The AirPrime HL8549-G module embeds a GPS/GLONASS receiver inside. A possible
implementation with an active GNSS antenna is defined below.
Figure 20. GNSS Application with Active Antenna
EXT_LNA_GPS_EN is a specific signal that automatically sets the AirPrime HL8549-G module
internal LNA to low gain when an external pull-down resistor is detected.
Note: When the application needs to monitor the active antenna current, current monitor devices can be
connected to any of the module’s GPIOs, and read with a dedicated AT command.

6. X-Ray Exposure
X-ray exposure results in an undesirable shift in programmed bit threshold voltage of the Flash
memory.
As a result, Sierra Wireless recommends avoiding any X-ray exposure during customer manufacturing
process to ensure software integrity and long term reliability.
In case X- ray inspection could not be eliminated from the customer manufacturing process, a variety
of mitigation methods should be implemented to lower the risk of potential failure:
Use of filter between source and module to minimize exposure to harmful soft X- ray
300µm Zn filter or 1mm Al filter are optimal
Zn and Al absorb soft X-ray to which silicon is particularly vulnerable, and transmit soft
and medium energy X-rays required to obtain good imaging
Minimize X-Ray dose
should be less than 10 RADs
KV peak should be less than 50KV peak
tube current should be less than 20µA
Maximize distance between source and the module
Minimize the X-ray time
use the shortest exposure time possible
sampling only, not 100% inspection
Note that these mitigation guidelines are for information only as it’s NOT possible to provide accurate
acceptable or unacceptable X- ray exposure criteria, e.g. maximum safe dose rate, maximum safe
exposure time, etc.

7. FCC Legal Information
The HL8549x module has been granted modular approval for mobile applications. Integrators may
use the HL8549x module 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:
TBD dBi in the cellular band
TBD dBi in the PCS band
3. The HL8549x module 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).
4115653 Rev 3.0 July 31, 2014 49
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 HL8549x module is
incorporated, with a statement similar to the following:
This device contains FCC ID: N7NHL8549G
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 HL8549x 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.
