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.

3.5. USIM Interface

The AirPrime HL7650 has two physical USIM interfaces, UIM1 and UIM2.

Both UIM1 and UIM2 allow control of a 1.8V/3V USIM and is fully compliant with GSM 11.11

recommendations concerning SIM functions.

The five signals used by the UIMx interface are as follows:

 UIMx_VCC: Power supply

 UIMx_CLK: Clock

 UIMx_DATA: I/O port

 UIMx_RESET: Reset

 UIMx_DET: Hardware SIM detection

UIM1 is used in single SIM applications, and has optional support for dual SIM applications with an

external SIM switch (for use in Dual SIM Single Standby (DSSS) applications).

A second UIM interface, UIM2, is also available for Dual SIM Single Standby (DSSS) option.

Note: Although UIM2 connectivity is available in the hardware, this feature is not activated in the firmware.

For USIM design examples, refer to section 5.9 USIM Application.

Refer to the following table for the pad description of both UIM interfaces.

3.5.2. UIMx_DET

UIMx_DET is used to detect and notify the application about the insertion and removal of a USIM

device in the USIM socket connected to the USIM interface (UIM1 or UIM2). When a USIM is

inserted, the state of UIMx_DET transitions from logic 0 to logic 1. Inversely, when a USIM is

removed, the state of UIMx_DET transitions from logic 1 to logic 0.

While UIM1_DET has a dedicated pad (pad 64), UIM2_DET is multiplexed with GPIO4 (pad 65).

3.10. POWER-ON Signal (PWR_ON_N)

A low-level signal has to be provided to switch the AirPrime HL7650 module ON.

It is internally connected to the permanent 1.8V supply regulator inside the HL7650 via a pull-up

resistor. Once VBAT is supplied to the HL7650 module, this 1.8V supply regulator will be enabled and

so the PWR_ON_N signal is by default at high level.

Refer to the following table for the pad description of the PWR_ON_N interface.

Input Voltage-High (V) 1.33 - 2.2

PWR_ON_N assertion time (ms) 25

Note: As PWR_ON_N is internally pulled up with 100kΩ, 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: PWR_ON_N signal cannot be used to power the module off. To power the module off, use AT

command

AT+CPWROFF

3.11. Reset Signal (RESET_IN_N)

To reset the module, a low-level pulse must be sent on the RESET_IN_N pad for 20ms. This action

will immediately restart the AirPrime HL7650 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.

The RESET_IN_N signal will reset the registers of the CPU and reset the RAM memory as well, for

the next power on.

Note: As RESET_IN_N is referenced to the VRTC (200kΩ pull-up resistor to VRTC 1.8V) an open

collector or open drain transistor has to be used to control this signal.

Refer to the following table for the pad description of the RESET_IN_N interface.

3.14. Digital Audio (PCM) Interface

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 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

 Long frame sync

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.

Refer to the following table for the pad description of the digital audio interface.

3.16. RF Interface

The RF interface of the AirPrime HL7650 module allows the transmission of RF signals. This interface

has a 50Ω nominal impedance.

Note that if the final application is a single antenna receiver (does not use the diversity antenna), it is

recommended that the diversity antenna be disabled using AT command AT+WMANTSEL. Disabling

the diversity antenna when not used:

 prevents any noise in the diversity antenna input from degrading the overall sensitivity

performance of the main RF input, and

 reduces the power consumption of the module.

Refer to document [2] AirPrime HL76xx AT Commands Interface Guide for more information

regarding AT+WMANTSEL.

3.16.1. RF Connection

A 50Ω (with maximum VSWR 1.1:1, and 0.5 dB loss) RF track is recommended to be connected to

standard RF connectors such as SMA, UFL, etc. for antenna connection.

Refer to the following tables for the pad description of the RF interface.

3.16.3. TX_ON Indicator (TX_ON)

The AirPrime HL7650 provides a signal, TX_ON, for TX indication. The TX_ON is a 2.3V (TBC) signal

and its status signal depends on the module’s transmitter state.

Refer to the following table for the pad description of the TX_ON signal.

Table 41. TX_ON Indicator Pad Description

Pad Number Signal Name Function I/O type Power Supply Domain

60 TX_ON TX indicator O 2.3V (TBC)

Refer to the following table for the status of the TX_ON signal depending on the embedded module’s

state.

Table 42. Burst Indicator States

Embedded Module State TX_ON

During TX burst High

No TX Low

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 217 Hz in 2G, continuous in 3G (TBC) and blinking in 4G at (TBC) Hz.

The output logic high duration, T

duration

, 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

5. Design Guidelines

5.1. Power-Up Sequence

Apply a low-level logic to the PWR_ON_N pad (pad 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 7 seconds 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 HL7650 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.

Figure 16. PWR_ON_N Sequence with VGPIO Information

Note: As PWR_ON_N is internally pulled up with 100kΩ, an open collector or open drain transistor must be

used for ignition.

The PWR_ON_N pad has the minimum assertion time requirement of 25ms, with LOW active. Once the

valid power on trigger is detected, the PWR_ON_N pad status can be left open.

5.2. Module Switch-Off

AT command AT+CPWROFF enables the user to properly switch the AirPrime HL7650 module off.

Figure 17. Power OFF Sequence for PWR_ON_N, VGPIO

Note: PWR_ON_N is internally pulled up by 100kΩ to 1.8V.

AT+CPWROFF=1

Figure 18. Fast Shutdown Power OFF Sequence

Note that the timings for fast detach and mobile shutdown (t3 and t4 in the diagram above) are

dependent on operators and network conditions.

Starting the shutdown procedure during the boot phase should be avoided as this may cause the

shutdown to take more time.

5.4. Emergency Power OFF

If required, the module can be switched off by controlling the RESET_IN_N pad (pad 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_IN_N pad for 20ms

while the PWR_ON_N signal is inactive (high level). This action will immediately shut the HL7650

module down and the registers of the CPU and RAM memory will be reset for the next power on.

5.5. Sleep Mode Management

AT command AT+KSLEEP enables sleep mode configuration. Note that this is only used with serial link

UART1.

AT+KSLEEP=0:

 The module is active when 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.

41110363 Rev 4.0 October 18, 2017 47

Product Technical Specification Design Guidelines

AT+KSLEEP=1:

 The module determines when it enters sleep mode (when no more tasks are running).

 “0x00” character on the serial link wakes the module up.

AT+KSLEEP=2: The module never enters sleep mode.

5.6. Power Supply Design

The AirPrime HL7650 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 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.

7. FCC Regulations

The HL7650 module has been granted modular approval for mobile applications. Integrators may use

the HL7650 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:

 5 dBi in LTE Band 5

3. The HL7650 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).

41110363 Rev 4.0 October 18, 2017 57

Product Technical Specification FCC Regulations

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 antenna 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 HL7650 module is

incorporated, with a statement similar to the following:

This device contains FCC ID: N7NHL7650

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 HL7650 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.
