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. Table 7. Pad Definition Pin #

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. 3.6. USB The AirPrime HL8549 and HL8549-G have one USB interface. Table 14.

This pin can be used to trigger the module to wake up from Sleep Mode. 4115653 Rev 3.0 July 31, 2014 27 Product Technical Specification Detailed Interface Specifications 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:

According to PC view. 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 signals characteristics are listed in the table below. 4115653 Rev 3.0 July 31, 2014 28 Product Technical Specification Detailed Interface Specifications Table 18.

Note:

As PWR_ON is internally pulled up with 200k, a simple open collector or open drain transistor must be used for ignition. The software starts operating when the module is ON, but AT Command Ready will depend on whether UART or USB is used. Figure 4. PWR_ON Assertion Time 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. Table 19.

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 Long frame sync Refer to the following table for the electrical characteristics of the digital audio interface.

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 modules state. Table 32. Burst Indicator States Embedded Module State 2G_TX_ON During TX burst No TX High 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 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 Table 33.

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 50 connection on RF_GPS pad. 3.22.1.

If the external net gain is lower than 16dB, it is advised to set the internal LNA gain in high gain. In any case, the external net gain should not exceed 24dB. 4115653 Rev 3.0 July 31, 2014 39 4. Mechanical Drawings Figure 10. AirPrime HL8549x Mechanical Drawing 4115653 Rev 3.0 July 31, 2014 40 Product Technical Specification Mechanical Drawings Figure 11. AirPrime HL8549x Footprint 4115653 Rev 3.0 July 31, 2014 41 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 200k, 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. 4115653 Rev 3.0 July 31, 2014 42 Product Technical Specification Design Guidelines Figure 14. Power OFF Sequence for PWR_ON, VGPIO Note:

PWR_ON is internally pulled up by 200k 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 43 Product Technical Specification 5.4.2. Using USB Design Guidelines Use AT+KSLEEP=1 to allows the module to automatically enter sleep mode while the USB interface is in use. 5.5. Power Supply Design The AirPrime HL8549x module should not be supplied with voltage over 4.5V even temporarily or however briefly. If the systems main board power supply unit is unstable or if the systems main board is supplied with over 4.5V, even in the case of transient voltage presence on the circuit, the HL8549xs power amplifier and GPS chipset may be severely damaged. To avoid such issues, add a voltage limiter to the modules 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. Figure 15. Voltage Limiter Example 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. Figure 16. EMC and ESD Components Close to the SIM 4115653 Rev 3.0 July 31, 2014 44 Power SupplyVBATT/VBATT_PAD4040.5 pFD405C4041.5 mF++C405150 FC407100 nF Product Technical Specification Design Guidelines 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. Figure 18. Reference Design for Dual SIM Application 4115653 Rev 3.0 July 31, 2014 45 Product Technical Specification Design Guidelines 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 50 line matching circuit between the module, the customers 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 10K. 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 modules GPIOs, and read with a dedicated AT command. 4115653 Rev 3.0 July 31, 2014 46 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 300m 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 20A 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 its NOT possible to provide accurate acceptable or unacceptable X- ray exposure criteria, e.g. maximum safe dose rate, maximum safe exposure time, etc. 4115653 Rev 3.0 July 31, 2014 47 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 users 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 50 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 48 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 50 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. 7.1. IC Regulations IC Radiation Exposure Statement:
