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. Limitations of Liability This manual is provided “as is”.

Pad Definition AirPrime HL7548 and HL7588 pads are divided into 3 functional categories. • Core functions and associated pads cover all the mandatory features for M2M connectivity and will be available by default across all CF 3 family of modules. These Core functions are always available and always at the same physical pad locations. A customer platform using only these functions and associated pads is guaranteed to be forward and/or backward compatible with the next generation of CF3 modules. • Extension functions and associated pads bring additional capabilities to the customer. Whenever an Extension function is available on a module, it is always at the same pad location. • Custom functions and associated pads 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 pads marked as “not connected” or “reserved” should not be used. Table 6.

Detailed Interface Specifications Note: If not specified, all electrical values are given for VBATT=3.7V and an operating temperature of 25°C. For standard applications, VBATT and VBATT_PA must be tied externally to the same power supply. For some specific applications, AirPrime HL7548 and HL7588 modules support separate VBATT and VBATT_PA connection if requirements below are fulfilled. 3.1. Power Supply The AirPrime HL7548 and HL7588 modules are supplied through the VBATT signal with the following characteristics. Table 7.

BAT_RTC The AirPrime HL7548 and HL7588 modules provide an input/output to connect a Real Time Clock power supply. This pad 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 1.8V power supply regulator. Table 11.

SIM Interface The AirPrime HL7548 and HL7588 have one physical SIM interface, UIM1, which has optional support for dual SIM application with an external SIM switch. The UIM1 interface allows control of a 1.8V/3V SIM and is fully compliant with GSM 11.11 recommendations concerning SIM functions. The five signals used by this interface are as follows: • UIM1_VCC: power supply • UIM1_CLK: clock • UIM1_DATA: I/O port • UIM1_RESET: reset • UIM1_DET: SIM detection Table 12.

Multiplex UIM1_DET Main Serial Link (UART1) The main serial link (UART1) is used for communication between the AirPrime HL7548 and HL7588 modules 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_DTR, UART1_DSR, UART1_DCD and UART1_RI are not available on the HL7548. UART1 pad description is summarized in the table below. Table 17.

POWER-ON Signal (PWR_ON_N) A low-level signal should be provided to switch the AirPrime HL7548 and HL7588 module ON. It is internally connected to the permanent 1.8V supply regulator inside the HL7548 or HL7588 via a pull-up resistor. Once VBAT is supplied to the HL7548 or HL7588 module, this 1.8V 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 = 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 HL7548 or HL7588 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: 4116369 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.

PCM Note: This interface is only available on the HL7588. 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/16 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, 512kHz, 768kHz or 1024kHz • Long frame sync The following table describes the pad description of the PCM interface.

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 UART1 or USB. When using UART1, the AT command interface is available after the transition of UART1_CTS from high to low level. When using a USB connection, the HL7548 and HL7588 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 VGPIO Module is ON 2000 ms
