Important Notice
Due to the nature of wireless communications, transmission and reception of data can never be
guaranteed. 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.

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.

3. 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.

Note:
Load capacitance for VBATT is around 32µF ± 20% embedded inside the module.
Load capacitance for VBATT_PA is around 10µF ± 20% embedded inside the module.
3.2.
Current Consumption
The following table lists the current consumption of the AirPrime HL7548 and HL7588 at different
conditions.
Note:
The following data is with USB disconnected to achieve the lowest current consumption. An
additional 0.6mA will be consumed if USB is connected.
Typical values are defined for VBATT/VBATT_PA at 3.7V and 25°C, for 50Ω impedance at all RF
ports. Maximum values are provided for VSWR3:1 with worst conditions among supported ranges
of voltages and temperature.

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.

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.

3.10. 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.

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.

3.14. 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
•

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.
