JTAG Timing Waveform 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.

41110555 Rev 1.0 September 21, 2017 39 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 September 21, 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. Power Supply VBATT/VBATT _PAD4040.5 pFD405C4041.5 mF ++C405150 µFC407100 nF Figure 11.

Design Application with USIM1 Slot 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.

41110555 Rev 1.0 September 21, 2017 49 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: TBD 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 September 21, 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 TBD 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.
