Detailed Interface Specifications SIM Interface The AirPrime HL7648 has one physical SIM interface, UIM1, which has optional support for dual SIM application with an external SIM switch. It allows control of a 1.8V/3V SIM and is fully compliant with GSM 11.11 recommendations concerning SIM functions.

Multiplex TRACE_DATA2 TRACE_CLK Main Serial Link (UART1) The main serial link (UART1) is used for communication between the AirPrime HL7648 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 and 3250000 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) Ring Indicator (UART1_RI) Note: Signal names are according to PC view. UART1 pad description is summarized in the table below. 4119069 Rev 3.1 October 27, 2016 25 Product Technical Specification Table 17.

UART1_DCD Signal data connection in progress UART1_DSR Signal UART interface is ON According to PC view. 3.10. POWER-ON Signal (PWR_ON_N) A low level signal has to be provided to switch the AirPrime HL7648 module ON. It is internally connected to the permanent 1.8 V supply regulator inside the HL7648 via a pull-up resistor. Once VBAT is supplied to the HL7648 module, this 1.8 V supply regulator will be enabled and so the PWR_ON_N signal is by default at high level. The PWR_ON_N signal’s characteristics are listed in the table below. Table 18. PWR_ON_N Electrical Characteristics Parameter Minimum Input Voltage-Low (V) Typical Maximum 0.51 Input Voltage-High (V) 1.33 2.2 Power-up period (ms) from PWR_ON_N falling edge 2000 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 = 0 V, the module is OFF When VGPIO = 1.8 V, 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. 4119069 Rev 3.1 October 27, 2016 26 Product Technical Specification Detailed Interface Specifications 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 20 ms. This action will immediately restart the AirPrime HL7648 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 has to 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. As RESET_IN_N is referenced to the VRTC (200 kΩ pull-up resistor to VRTC 1.8 V) an open collector or open drain transistor has to be used to control this signal. Note: Table 19.

For more information about AT commands, refer to document [2] AirPrime HL76xx AT Commands Interface Guide. 3.14. Digital Audio (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 PCM 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 following table describes the pad description of the PCM interface. 4119069 Rev 3.1 October 27, 2016 28 Product Technical Specification Table 23.

Design Guidelines 5.1. Power-Up Sequence Apply a LOW level logic to the PWR_ON_N pad (pad 59); within approximately 25 ms, VGPIO will appear to be at 1.8 V. 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 HL7648 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. Module is OFF PWR_ON_N Module is ON 2000 ms < 25 ms VGPIO Module is ready to receive AT commands via UART1 Signal level depends on Hardware Flow Control settings 7 seconds UART1_CTS Figure 8. PWR_ON_N Sequence with VGPIO Information USB_D+ Module communicates with host via USB USB Enumeration time As PWR_ON_N is internally pulled up with 100kΩ, an open collector or open drain transistor must (7 seconds) be used for ignition. Note: The PWR_ON_N pad has the minimum assertion time requirement of 25 ms, 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 HL7648 module off. AT+CPWROFF Module is ON PWR_ON_N Internal pull-up to 1V8 Module is OFF 2 seconds VGPIO Figure 9. Note: 4119069 Power OFF Sequence for PWR_ON_N, VGPIO PWR_ON_N is internally pulled up by 100kΩ to 1.8 V. Rev 3.1 October 27, 2016 35 Product Technical Specification 5.3. Design Guidelines 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 20 ms while the PWR_ON_N signal is inactive (high level). This action will immediately shut the HL7648 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 UART1 AT command AT+KSLEEP enables sleep mode configuration. 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. 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. 5.4.2. Using USB 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 HL7648 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. 4119069 Rev 3.1 October 27, 2016 36 Product Technical Specification Design Guidelines Power Supply Figure 10. 5.6.

A typical schematic including SIM detection is provided below. Figure 11. 4119069 EMC and ESD Components Close to the SIM Rev 3.1 October 27, 2016 37 Product Technical Specification 5.7. Design Guidelines 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 12. Note: ESD Protection for USB It is not recommended to have an ESD diode with feedback path from USB_VBUS to either USB_D+ or USB_D-. Sierra Wireless recommends using a 90Ω DLP0NSN900HL2L EMC filter and an RCLAMP0503N or ESD5V3U2U-03LRH ESD diode. 4119069 Rev 3.1 October 27, 2016 38 6.

FCC Legal Information The HL7648 module has been granted modular approval for mobile applications. Integrators may use the HL7648 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: 8.01 dBi in LTE Band 2 5.00 dBi in LTE Band 4 8.70 dBi in LTE Band 12 3. The HL7648 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 Ω 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). 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. 4119069 Rev 3.1 October 27, 2016 44 Product Technical Specification FCC Legal Information 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 3 cm), 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 (microcontrollers, etc.) may degrade the reception performances. The GSM/GPRS connector is intended to be directly connected to a 50 Ω antenna and no matching is needed. 5. A label must be affixed to the outside of the end product into which the HL7648 module is incorporated, with a statement similar to the following: This device contains FCC ID: N7NHL7648 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. FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. IMPORTANT NOTE – FCC Radiation Exposure Statement: This Modular Approval is limited to OEM installation for mobile and fixed applications only. The antenna installation and operating configurations of this transmitter, including any applicable sourcebased time-averaging duty factor, antenna gain and cable loss must satisfy MPE categorical Exclusion Requirements of §2.1091. The antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons, must not be collocated or operating in conjunction with any other antenna or transmitter, except in accordance with FCC multi-transmitter product procedures. The end user has no manual instructions to remove or install the device and a separate approval is required for all other operating configurations, including portable configurations with respect to 2.1093 and different antenna configurations. When the module is installed in the host device, the FCC ID label must be visible through a window on the final device or it must be visible when an access panel, door or cover is easily removed. Otherwise, a second label must be placed on the outside of the final device that contains the following text: Contains FCC ID: N7NHL7648. The end product with an embedded HL7648 module may also need to pass the FCC Part 15 unintentional emission testing requirements and be properly authorized per FCC Part 15. 4119069 Rev 3.1 October 27, 2016 45 8.
