Product Technical Specification and
Customer Design Guidelines
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.
Do not operate the Sierra Wireless modem in areas where blasting is in progress, where explosive
atmospheres may be present, near medical equipment, near life support equipment, or any
equipment which may be susceptible to any form of radio interference. In such areas, the Sierra
Wireless modem MUST BE POWERED OFF. 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.

The Q26 Extreme Wireless CPU® is designed to integrate various types of specific process applications
such as vertical applications (telemetry, multimedia, automotive).
The Operating System offers a set of AT commands to control the Wireless CPU®. With this standard
Operating System, some interfaces of the Wireless CPU® are not available, since they are dependent
on the peripheral devices connected to the Wireless CPU®.
The Operating System is Open AT® compliant.

Ground
The Q26 Extreme Wireless CPU® shielding case is the grounding. The ground must be connected to
the motherboard through a complete layer on the PCB.

(2): Max operating Voltage Stationary Wave Ratio (VSWR) 2:1
Impedance
When the Wireless CPU® is supplied with a battery, the total impedance (battery + protections + PCB)
should be < 150 mΩ.
Recommendations when using DC/DC converter
As the radio power amplifier is directly connected to VBATT, the Wireless CPU® is sensitive to any
Alternative Current on lines. When a DC/DC converter is used, Wavecom recommends setting the
converter frequency in such a way that the resulting voltage does not exceed the values in following
table.

When the Wireless CPU® is in Alarm/Off mode, no voltage has to be applied on any pin of the 100-pin
connector, except on Vbatt (pins 1 to 4), BAT-RTC (pin 7) for RTC operation or ON/~OFF (pin 19) to
power-ON the Wireless CPU®.
Details
Due to the burst emission mode used in GSM/GPRS/EGPRS, the power supply must be able to deliver
high current peaks in a short time. During the peaks, the ripple (Uripp) on the supply voltage must not
exceed a certain limit).
In communication mode, a GSM/GPRS class 2 terminal emits 577µs radio bursts every
4.615ms.
Figure 2. Power supply during GSM burst emission
Directly supplies the RF components with 3.8 V. It is essential to keep a minimum voltage
ripple at this connection in order to avoid any phase error.
The RF Power Amplifier current (2.1A max peak in GSM /GPRS mode) flows with a ratio of:
1/8 of the time (577µs every 4.615ms for GSM /GPRS cl. 2) and
2/8 of the time (1154µs every 4.615ms for GSM /GPRS cl. 10).
4/8 of the time (2302µs every 4.615ms for GSM /GPRS cl. 12).
The rising time is around 10µs.
Attention should be paid:
to the quality of the power supply:
linear regulation (recommended) or PWM (Pulse Width Modulation) converter (usable) are
preferred for low noise.
WM_DEV_Q26EX_PTS_002 Rev 006 Page 24 of 112

PFM (Power Frequency Modulation) or PSM (Phase Shift Modulation) system must be
avoided.
to the capacity to deliver high current peaks in a short time (burst radio emission).
that the VBATT line supports peak currents with an acceptable voltage drop which
guarantees a VBATT minimal value of 3.4V.
For PCB design constraints related to power supply tracks, ground planes and shielding, refer to the
Design Guidelines section.
Decoupling capacitors on VBATT lines are embedded in the Wireless CPU. Hence, it should not be
necessary to add decoupling capacitors close to the Wireless CPU.
However, in case of EMI/RFI problem, VBATT signal may require some EMI/RFI decoupling: parallel
33 pF capacitor close to the Wireless CPU or a serial ferrite bead (or both to get better results). Low
frequency decoupling capacitors (22µF to 100µF) may be used to reduce the TDMA noise (217Hz).
Caution: When ferrite beads are used, the recommendation given for the power supply connection must
be followed with care (as high current capacity and low impedance).
Power consumption is dependent on the configuration used. It is for this reason that the following
consumption values are given for each mode, RF band and type of software used (AT or Open AT®).
All the following information is given assuming a 50 ohms RF output.
The following consumption values were obtained by performing measurements on the Wireless
CPU® samples at a temperature of 25° C.
Three VBATT values are used to measure the consumption, VBATTmin (3.4V), VBATTmax (4.2V) and
VBATTtyp (3.8V).
The average current is given for the three VBATT values and the peak current given is the maximum
current peak measured with the three VBATT voltages.
For a more detailed description of the operating modes, see the appendix of the AT Command User
Guide [5].
First let’s define start-up current in view to avoid start issues.
The following measurement results are relevant when there is no Open AT® application.
For explanation of power consumption mode, please Open AT® feature navigator document available
on Wavecom website.

This Mode consumption is dependent on the USIM card used. Some USIM cards respond faster than others, the longer
the response time, the higher the consumption. The measurements were performed with a large number of 3V USIM
cards, the results in brackets are the minimum and maximum currents measured from among all the USIMs used.
The activation of the Open AT® software could increase the power consumption up to 60mA in
ACTIVE mode and CONNECTED when the full CPU load is used by the Open AT® application.
Table 8. Power supply pin-out
Caution: The grounding connection is made through the shielding the four leads must be soldered to
the ground plane.

The Q26 Extreme Wireless CPU® provides two SPI bus (i.e. for LCD, memories…). or an I²C 2-wire
interface.
Both SPI bus interfaces include:
A CLK signal
An I/O signal
An I signal
A CS (Chip Select) signal complying with the standard SPI bus (any GPIO).
An optional Load signal (only the SPIx-LOAD signal)
Master mode operation
The CS signal must be any GPIO
The LOAD signal (optional) is used for the word handling mode (only the SPIx-LOAD signal)
SPI speed is from 102 kbit/s to 13 Mbit/s in master mode operation
3 or 4-wire interface(5-wire possible with the optional SPIx-LOAD signal)
SPI-mode configuration: 0 to 3
1 to 16 bits data length

For the 3-wire configuration, SPIx-I/O is used as input and output.
For the 4-wire configuration, SPIx-I/O is used as output only, SPIx-I is used as input only.
For the 5-wire configuration, SPIx-I/O is used as output only, SPIx-I is used as input only. And the dedicated SPIx-LOAD
signal is used. It is an additional signal in more than a Chip Select (any other GPIOx)
Waveforms for SPI transfer with 4-wire configuration in master mode 0.
