4114016 Rev 3.0 January 28, 2014 18 2. Pad Definition AirPrime HL6528x module pins are divided into 3 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.  Custom functions and associated pins are specific to a given module, and make an opportunistic use of specific chipset functions and I/Os. Custom features should be used with caution as there is no guarantee that the custom functions available on a given module will be available on other CF3 modules. Other pins marked as “not connected” or “reserved” should not be used. Table 6.

BAT_RTC The AirPrime HL6528x module provides an input/output to connect a Real Time Clock power supply. This pin is used as a back-up power supply for the internal Real Time Clock. The RTC is supported when VBATT is available but a back-up power supply is needed to save date and hour when VBATT is switched off. If VBATT is available, the back-up battery can be charged by the internal 3.0V power supply regulator. Table 11.

Main Serial Link (UART1) The main serial link (UART1) is used for communication between the AirPrime HL6528x 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 1200, 2400, 4800, 9600, 19200, 38400, 57600 and 115200 bit/s, with autobauding and up to 1Mbit/s at maximum baud rate. 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) UART1 pin description is summarized below. Table 16. UART1 Pin Description Signal Name (Module side) I/O (Module side) Description UART1_DTR I (active low) Prevents the AirPrime HL6528x from entering sleep mode, switches between data mode and command mode, and wakes the module up.

4114016 Rev 3.0 January 28, 2014 31 Product Technical Specification Detailed Interface Specifications 3.8. Power On Signal (PWR_ON) A low level signal has to be provided to switch the AirPrime HL6528x module ON. It is internally connected to the permanent 3.0V supply regulator inside the HL6528x via a pull-up resistor. Once VBATT is supplied to the HL6528x module, this 3.0V supply regulator will be enabled and so PWR_ON signal is by default at high level. The PWR_ON signal’s characteristics are listed in the table below. Table 17. PWR_ON Electrical Characteristics Parameter Minimum Typical Maximum Input Voltage-Low (V) - 0.4 Input Voltage-High (V) 2.4 - 3.3 Power-up period (ms) from PWR_ON falling edge 2000 - - Note: As PWR_ON is internally pulled up, a simple open collector or open drain transistor must be used for ignition. The PWR_ON signal will become low after the module is ready. It cannot be directly driven by a GPIO signal. 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 = 2.8V or 1.8V the module is ON (it can be in Idle, Communication or Sleep mode) After a few seconds, the UART1_CTS enters active state and the module is ready to receive AT commands. Figure 5. PWR_ON Sequence Note: PWR_ON cannot be used to power the module off. The module is powered off with AT command “AT*PSCPOF”.
4114016 Rev 3.0 January 28, 2014 32 Product Technical Specification Detailed Interface Specifications 3.9. Reset Signal (RESET) To reset the module, a low level pulse must be sent on RESET pin for at least 10ms. This action will immediately restart the AirPrime HL6528x module. It is therefore useless to perform a new ignition sequence (PWR_ON) afterwards. 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. 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 the RESET as a way to start the module.

ADC Two Analog to Digital Converter input, ADC0 and ADC1 are provided by the AirPrime HL6528x module. These converters are 10-bit resolution ADCs ranging from 0 to 3V. 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 OFF the application in case of overheating (for Li-Ion batteries). Both ADCs have the characteristics listed in the table below. Table 18.

Analog Audio Interfaces The AirPrime HL6528x module supports one differential microphone input and one differential speaker output. It also includes a noise suppression and echo cancellation feature which allows for an enhanced voice call quality.
4114016 Rev 3.0 January 28, 2014 33 Product Technical Specification Detailed Interface Specifications 3.11.1. Analog Audio Input The microphone input can either have a single-ended or a differential connection. However, performance with common mode noise and TDMA noise varies depending on the connection mode and PCB layout. When connecting a microphone to the AirPrime HL6528x module, ensure to have a very good ground plane, very good filtering as well as shielding in order to avoid any disturbance on the audio path. The gain of the microphone input can be tuned using AT commands. The AirPrime HL6528x module microphone pins already include suitable biasing for an electret microphone. The electret microphone can then be connected directly on the inputs for easy connection. AC coupling is also already embedded in the HL6528x embedded module. Table 19.

PCM The Digital Audio Interface (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 8KHz frequency pulse that synchronizes the frame “data in” and the frame “data out” (short frame synchronization only).  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 mode  8 bits or 16 bits data word length  MSB or LSB first  Rising or falling sampling clock edge  Configurable PCM bit clock rate up to 1MHz Refer to the following table for the electrical characteristics of the digital audio interface.

TX Burst Indicator (2G_TX_ON) The AirPrime HL6528x module provides a signal, 2G_TX_ON, for TX burst indication. 2G_TX_ON is a 2.8V signal and its status depends on the module transmitter state.
4114016 Rev 3.0 January 28, 2014 38 Product Technical Specification Detailed Interface Specifications Refer to the following table for the status of the 2G_TX_ON signal depending on the embedded module’s state. Table 29. Burst Indicator States Embedded Module State 2G_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 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 30.

GNSS Interface The AirPrime HL6528-G and HL6528-G2.8V modules embed an integrated and high-sensitivity Global Navigation Satellite System (GNSS) solution. Based on SiRFstarV™ from CSR, the AirPrime HL6528-G and HL6528-G2.8V modules combine 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 Downloaded Extended Ephemeris Assisted-GNSS, for enhanced time to acquire or reacquire a fix.

When CTS is toggling to low level, the module is ready to receive AT commands. Figure 12. UART Signals during the Power ON Sequence 5.2. Module Switch-Off AT command AT*PSCPOF enables the user to properly switch the AirPrime HL6528x module 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 HL6528x module. In this case, the only way to get control back over the module is to switch off the power line. VGPIO, PWR_ON and CTS signal behavior during the power off sequence is described in the figure below.

4114016 Rev 3.0 January 28, 2014 47 Product Technical Specification Design Guidelines 5.3. Sleep Mode Management AT command AT+KSLEEP enables the sleep mode configuration. AT+KSLEEP=0:  The AirPrime HL6528x module is active when DTR signal is active (low electrical level).  When DTR is deactivated (high electrical level), the AirPrime HL6528x module enters sleep mode after a while.  On DTR activation (low electrical level), the AirPrime HL6528x module wakes up. AT+KSLEEP=1:  The AirPrime HL6528x module determines when it enters sleep mode (when no more tasks are running).  “0x00” character on the serial link wakes the AirPrime HL6528x module up. AT+KSLEEP=2:  The AirPrime HL6528x module never enters sleep mode. In sleep mode, the module reduces its power consumption and remains waiting for the wake up signals either from the network (i.e. read paging block depending on the DRX value of the network) or the operating system (i.e. timers wake up timers activated) or the host controller (i.e. character on serial link or DTR signal). 5.4. ESD Guidelines for UIM Cards Decoupling capacitors must be added as close as possible to the UIM card connectors on UIM_CLK, UIM_RST, UIM_VCC and UIM_DATA signals to avoid EMC issues and to pass the UIM card type approval tests, according to the drawings below (this applies to both UIM slots, UIM1 and UIM2).

Very good grounding on the MIC is required in order to ensure good performance against TDMA. Also, special care on the PCB layout must be taken. When not used, the filter can be removed by replacing L1 with a 0Ω resistor and by disconnecting C2, as shown in the following figure. Figure 18. Example of a Single-Ended MIC Input Connection without LC Filter
4114016 Rev 3.0 January 28, 2014 50 Product Technical Specification Design Guidelines The capacitor C1 is highly recommended to eliminate TDMA noise, and it must be placed close to the microphone. Refer to the table below for the recommended components to use with a single-ended microphone connection. Table 36. Recommended Components for a Single-Ended Microphone Connection Component Description/Details Notes C1 12pF to 33pF Needs to be tuned depending on the design C2 12pF to 33pF Needs to be tuned depending on the design L1 100nH Needs to be tuned depending on the design 5.5.2. Speaker Audio Design The SPKR interface can be used in a single-ended or a differential connection. However, it is strongly recommended to use a differential connection in order to reject common mode noise and TDMA noise. Moreover, in single-ended mode, half (1/2) of the power is lost. When using a single-ended connection, be sure to have a very good ground plane, very good filtering as well as shielding in order to avoid any disturbance on the audio path. The following table lists the typical values of both speaker output. Table 37. Speaker Details Parameter Typical Value Connection Z (SPKR_P, SPKR_N) (Ω) 32 Differential mode Z (SPKR_P, SPKR_N) (Ω) 32 Single-ended mode It is recommended to add ESD protection to the speaker when it is exposed to the external environment. The ESD protection should be connected between the audio lines and a good ground, and placed as close to the speaker as possible. It is important to select an appropriate speaker and filtering components to avoid TDMA noise. 5.5.2.1.1. SPKR Differential Connection Note: Add a 33pF capacitor between the SPKR_P and SPKR_N pins to reduce TDMA noise. 18pFSPKR_PSPKR_NSPEAKER HL6528x Figure 19.

Example of a Single-Ended Speaker Connection (typical implementation) In a single-ended connection:  4.7µF < C1 < 47µF, depending on the speaker characteristics and output power  the connection between the AirPrime HL6528x module pins and the speaker must be designed to keep the serial impedance lower than 1.5Ω  SPKR_N can be left open  output power is lost (-6dB) as compared to a differential connection 5.5.3. Audio Layout Guidelines To avoid TDMA noise, it is recommended to surround the audio tracks with ground as shown in the following figure. Figure 21. Audio Track Design For differential connections, refer to the on following figure. Note that the differential audio line is always in parallel.
4114016 Rev 3.0 January 28, 2014 52 Product Technical Specification Design Guidelines Figure 22. Differential Audio Connection For single-ended connections, the negative pole of the microphone, MIC_N, should be connected to GND. Refer to the following figure. Figure 23. Single-Ended Audio Connection Caution: Avoid digital tracks crossing under and over the audio tracks. It is highly recommended to have the MIC ground and the LC filter ground to act as an audio analog ground during the PCB layout. This audio ground, together with the MIC_P signal, should act as the differential line pair; and this audio ground should only be connected to the AirPrime HL6528x module ground, as close as possible to the LGA GND pad of the AirPrime HL6528x module. It is the same case for SPKR_P and SPKR_N. Also, the audio interface is ESD sensitive. ESD protection MUST be added to the interface once it is externally accessible. To avoid distortion and burst noise, the following guidelines should be followed:  Audio signals must be symmetric (same components on each path)  Differential signals must be routed in parallel  Audio layer must be surrounded by 2 ground layers  The link from one component to the ground must be as short as possible  Separate the PCBs for the microphone and the speaker if possible  Reduce the number of electronic components as much as possible (to avoid loss of quality and greater dispersion)  Audio tracks must be wider than 0.5 mm
4114016 Rev 3.0 January 28, 2014 53 Product Technical Specification Design Guidelines 5.6. Radio Integration 5.6.1. RF Routing Recommendations To route the RF antenna signals, the following recommendations must be observed for PCB layout: The RF signals must be routed using traces with a 50  characteristic impedance. Basically, the characteristic impedance depends on the dielectric constant (εr) of the material used, trace width (W), trace thickness (T), and height (H) between the trace and the reference ground plane. In order to respect this constraint, Sierra Wireless recommends that a MicroStrip structure be used and trace width be computed with a simulation tool (such as AppCAD, shown in the figure below and available free of charge at http://www.avagotech.com). Figure 24. AppCAD Screenshot for Microstrip Design Power Mode Diagram The trace width should be wide enough to maintain reasonable insertion loss and manufacturing reliability. Cutting out inner layers of ground under the trace will increase the effective substrate height; therefore, increasing the width of the RF trace. Caution: It is critical that no other signals (digital, analog, or supply) cross under the RF path. The figure below shows a generic example of good and poor routing techniques.
4114016 Rev 3.0 January 28, 2014 54 Product Technical Specification Design Guidelines Poor routing Correct routing The yellow traces cross the RF trace. There is no signal around the RF path. Figure 25. RF Routing Examples  Fill the area around the RF traces with ground and ground vias to connect inner ground layers for isolation.  Cut out ground fill under RF signal pads to reduce stray capacitance losses.  Avoid routing RF traces with sharp corners. A smooth radius is recommended. E.g. Use of 45° angles instead of 90°.  The ground reference plane should be a solid continuous plane under the trace.  The coplanar clearance (G, below) from the trace to the ground should be at least the trace width (W) and at least twice the height (H). This reduces the parasitic capacitance, which potentially alters the trace impedance and increases the losses. E.g. If W = 100 microns then G = 200 microns in an ideal setup. G = 150 microns would also be acceptable is space is limited. Figure 26. Coplanar Clearance Example Note: The figure above shows several internal ground layers cut out, which may not be necessary for every application.

GSM Antenna Integration with Antenna Detection Circuitry The AirPrime HL6528x module 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 28. 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.

GNSS Active Antenna Integration The AirPrime HL6528-G and HL6528-G2.8V modules embed a GPS/GLONASS receiver inside. A possible implementation with an active GNSS antenna is defined below. Figure 29. GNSS Application with Active Antenna EXT_LNA_GPS_EN is a specific signal that automatically sets the AirPrime HL6528-G and HL6528-G2.8V modules’ 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.
4114016 Rev 3.0 January 28, 2014 57 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. Flash memory endurance As many embedded device, the AirPrime HL6528x module is using flash memory which are guaranteed for a limited number of program/erasing cycles per sector (100,000 cycles). Although state-of-the-art mechanism has been implemented to limit the number of writing/erasing cycles, Sierra Wireless recommends using “writing” AT commands appropriately and with caution. Those AT commands are identified in the AirPrime HL6 and HL8 Series AT Commands Interface Guide [2]. 8. FCC/IC Legal Information 8.1. Label The AirPrime HL6528x module is labeled with its own FCC ID on the shield side. Each HL6528x variant has its own FCC ID as listed in the table below.
