1.3 Firmware
WISMO Quik Q24x6 sub-series is designed to be integrated into various types of applications such
as handsets or vertical applications (telemetry, multimedia,…).
For vertical applications, the firmware offers a set of AT commands to control the module (for further
information, refer to document [3]).
Please be aware that some of these interfaces can not be handled when using the WISMO
Quik Q24x6 sub-series driven by AT commands: LCD interface, auxiliary serial link interface
and SPI bus.
This symbol is used to indicate the interfaces not available with AT commands.
AAATTT
These functions have then to be managed externally i.e using the main processor of the
application.

2 Interfaces
Note:
Some of the WISMO interface signals are multiplexed in order to limit number of pins but this
architecture implies some limitation.
For example, in case of using SPI bus, 2-wire bus cannot be used.
Warning:
All external signals must be inactive when the WISMO module is OFF to avoid any damage
when starting and allow WISMO module to start correctly.
2.1 General Purpose Connector (GPC)
A 60-pin connector, with 0.5 mm pitch, is provided to interface the WISMO Quik Q24x6 sub-series
with a board containing either a LCD module, or a keyboard, or a SIM connector, or a battery
connection...

2.2 Power supply
2.2.1 General description
The power supply is one of the key issues in the design of a GSM terminal. Due to the bursted
emission in GSM / GPRS, the power supply must be able to deliver high current peaks in a short
time. During these peaks the ripple (Uripp) on the supply voltage must not exceed the limits specified
in table “Power Supply Voltage” hereafter.
In communication mode, a GSM/GPRS class 2 terminal emits 577 µs radio bursts every 4.615 ms.
In communication mode, a GPRS class 10 terminal emits 1154 µs radio bursts every 4.615 ms.

Figure 2: Typical power supply voltage in GSM mode
Two different inputs are provided for the power supply:
• the first one, VBATT is used to supply the RF part,
• the second one, VDD is used to supply the baseband part.
Notes:
• It is possible to connect VBATT to VDD.
• In case of separate power supplies, they have to be in the same state i.e both active or
inactive at the same time.
VBATT: supplies directly the RF components with 3.6 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 (2.0 A
peak in GSM /GPRS mode with a 50 Ohms RF output flows with a ratio of:
• 1/8 of the time (around 577 µs every 4.615 ms for GSM/GPRS class 2),
• 2/8 of the time (around 1154 µs every 4.615 ms for GSM/GPRS class 10).
The rising time is around 10 µs.
VDD: supplies the +2.8 V ballast regulators of the WISMO module. It is essential to keep the voltage
over 3.1 volts.
The WISMO module shielding case is the grounding. The ground has to be connected on the mother
board through a complete layer on the PCB.

2.7 Main serial link (UART1)
A flexible 6-wire serial interface is available complying with V24 protocol signaling but not with V28
(electrical interface) due to a 2.8 Volts interface.
The signals are:
• TX data (CT103/TX),
• RX data (CT104/RX),
• Request To Send (CT105/RTS),
• Clear To Send (CT106/CTS),
• Data Terminal Ready (CT108-2/DTR),
• Data Set Ready (CT107/DSR).
The set of serial link signals can be required for GSM DATA services application and is generated
by the general purpose I/O provided by the WISMO module.
The 2 additional signals are Data Carrier Detect (CT109/DCD) and Ring Indicator (CT125/RI).

2.9.2 SIM 3/5V management
The WISMO Quik Q24x6 sub-series module is designed to interface with 3 V SIMs only1.
Nevertheless, it is possible to manage 3 V and 5 V SIM cards using an external level shifter (refer to
customer design guidelines [1]). In this case, depending on the type of SIM detected, the module
firmware triggers the GPO0 output signal (pin #26) in order to properly set the external SIM driver
level (3V or 5V).

2.13 Audio interface
Two different microphone inputs and two different speaker outputs are supported.
The WISMO Quik Q24x6 sub-series also includes an echo cancellation feature which allows hands-
free function.
In some case, ESD protection must be added on the audio interface lines.
2.13.1 Microphone inputs
The MIC2 inputs already include the biasing for an electret microphone allowing an easy connection
to a handset.
The MIC1 inputs do not include an internal bias. MIC1/SPK1 is then appropriate for a hands-free
system or a handset with biasing external to the module.
2.13.1.1 Common microphone inputs characteristics
The connection can be either differential or single-ended but using a differential connection in order
to reject common mode noise and TDMA noise is strongly recommended. When using a single-
ended connection, be sure to have a very good ground plane, a very good filtering as well as
shielding in order to avoid any disturbance on the audio path.

2.13.2.1 Common speaker outputs characteristics
The connection can be differential or single-ended but using a differential connection to reject
common mode noise and TDMA noise is strongly recommended. Morover in single-ended mode, ½
of the power is lost. When using a single-ended connection, be sure to have a very good ground
plane, a very good filtering as well as shielding in order to avoid any disturbance on the audio path.
Speaker outputs SPK1 and SPK2 are push-pull amplifiers and can be loaded down to 150 Ohms
and up to 1 nF (see details in table Speaker gain vs Max output voltage).
Impedance of the speaker amplifier output in differential mode is :
R ≤ 1Ω +/-10 %.
These outputs are differential and the output power can be adjusted by step of 2 dB. The output can
be directly connected to a speaker.
Using a single-ended connection also includes losing half of the output power compared to a
differential connection.
The gain of the speaker outputs is internally adjusted and can be tuned using an AT command.

2.14 Battery charging interface
2.14.1 Hardware description
The WISMO module supports one battery charging circuit for Li-Ion batteries.
This circuit uses an interface which consists of a current source inputs (CHG_IN) where the constant
current has to flow in order to charge the battery.
This current value depends on the battery capacity. It is recommended to provide a current equal to
the value of the capacity plus 50 mA. For a 550 mA battery the current will be 600 mA. The
maximum current is 800 mA.
A specific AT command (AT+WBCM), available from 4.3 level, allows to manage the battery charge
(start and stop the charge, enable or disable unsolicited Battery Charge Indications and set the
battery charge parameters).
The WISMO module monitors the battery voltage to detect the end of the charge.
The WISMO module also monitors the temperature of the battery through the BAT_TEMP pin which
has to be connected to a temperature sensor inside the battery (a NTC resistor for instance).

* To be parametrized as per battery manufacturer
2.14.2 Li-ion charging procedure
A constant current source has to be provided through CHG_IN inputs in order to charge the Li-ion
battery, and BAT_TEMP input has to be connected to a battery temperature sensor. During this
procedure the voltage of the battery is accurately monitored.
The Li-ion charging involves two phases:
• During the first phase, the battery is charged with a constant current until its voltage reaches
4.1 V*,
• During the second phase, the constant current is pulsed by the module. The width and the
frequency of the pulse change during this phase in order to ensure a safety charge.
The battery is considered as fully charged when, after a pulse, the voltage remains at a 4.1 V*
during more than 10 s.
The Li-ion battery must have an included safety circuit to avoid any discharge or overcharge. This
circuit is delivered by the manufacturer inside the battery pack. The impedance of this safety circuit
has to be the lowest possible in order to reduce the drop-out of the voltage. This drop-out is due to
the RF Power Amplifier current (up to 2.0 A). A maximum of 150 mΩ is required.

2.15.2 Operating sequences
2.15.2.1 Power ON
Once the module is supplied by the power source, the application must set the ON/~OFF signal to
high to start the module power ON sequence.
The ON/~OFF signal must be held for 1 s minimum. After this time, an internal mechanism keeps it
on hold. During the power ON sequence, an internal reset is automatically performed by the module
for 240 ms (typical). During this phase, any external reset should be avoided.
Once the initialisation is complete (timing is SIM and network dependent) the AT interface answers
« OK » to the application2. For further details, please refer to the AT commands documentation

This signal can also be used to provide a reset to an external device. It then behaves as an output. If
no external reset is necessary this input can be left open. If used (emergency reset), it has to be
driven by an open collector or an open drain output:
• ∼RST pin 14 = 0, for Module Reset,
• ∼RST pin 14 = 1, for normal mode.

Additional comments on RESET:
The RESET process is activated either by the external ~RST signal or by an internal signal (coming
from a RESET generator). This automatic reset is activated at Power-up.
The module remains in RESET mode as long as the ~RST signal is held low.
This signal should be used only for “emergency” resets.
A software reset is always preferred to a hardware reset.

2.17.2 Reset sequence
To activate the « emergency » reset sequence, the ~RST signal has to be set to low for 500 µs
minimum.
As soon as the reset is complete, the AT interface answers « OK » to the application. For this, the
application has to send AT↵. If the application manages hardware flow control, the AT command
can be sent during the initialisation phase. Another solution is to use the AT+WIND command to get
an unsollicited status from the module.
For further details, refer to AT commands documentation [3].

2.18 External Interrupt (~INTR)
The WISMO module provides an external interrupt input ~INTR. This input is very sensitive and an
interrupt is activated on high to low edge. If this signal is not used it can be left open. If used this
input has to be driven by an open collector or an open drain output.
This input is used for instance to power OFF automatically the module.

2.21.1 RF connections
2.21.1.1 General
There are two possible ways to connect an antenna to the module:
• The antenna can be directly connected to the module on the "Antenna pad" by using a spring
contact.
• The antenna can be connected to the module through a coaxial cable. The coaxial cable is
connected to both the "Round pad" and the "Ground pad".
Spring contact
Two land patterns set on the PCB support the RF connection which can be used by the
application through spring contacts or a soldered RF cable.
Since no standard spring contact is available for WISMO Quik Q24x6 sub-series, this solution
requires a specific part to be developed.
Soldered solution
The soldered solution will preferably be based on a RG178 coaxial cable.

Figure 6: Antenna connection
Note:
• The WISMO Quik Q24x6 sub-series does not include any antenna switch for a car kit but
this function can be implemented externally and it can be driven using a GPIO.
• The antenna cable and connector should be chosen in order to minimise losses in the
frequency bands used for GSM 850/E-GSM 900MHz and DCS 1800/PCS 1900MHz.
• 0.5 dB can be considered as a maximum value for loss between the module and an external
connector.
2.21.1.2 Antenna directly connected to the module: matching circuit
The goal of the matching circuit is to link the antenna (impedance ZA) to the receiver and transmitter
access of the module (impedance ZL = 50 Ohm real).

4.3 Safety recommendations (for information only)
IMPORTANT
FOR THE EFFICIENT AND SAFE OPERATION OF
YOUR GSM APPLICATION BASED ON WISMO Quik Q24x6 Series
PLEASE READ THIS INFORMATION CAREFULLY
4.3.1 RF safety
4.3.1.1 General
Your GSM terminal3 is based on the GSM standard for cellular technology. The GSM standard is
spread all over the world. It covers Europe, Asia and some parts of America and Africa. This is the
most used telecommunication standard.
Your GSM terminal is actually a low power radio transmitter and receiver. It sends out and receives
radio frequency energy. When you use your GSM application, the cellular system which handles
your calls controls both the radio frequency and the power level of your cellular modem.
4.3.1.2 Exposure to RF energy
There has been some public concern about possible health effects of using GSM terminals.
Although research on health effects from RF energy has focused on the current RF technology for
many years, scientists have begun research regarding newer radio technologies, such as GSM.
After existing research had been reviewed, and after compliance to all applicable safety standards
had been tested, it has been concluded that the product was fitted for use.
If you are concerned about exposure to RF energy there are things you can do to minimize
exposure. Obviously, limiting the duration of your calls will reduce your exposure to RF energy. In
addition, you can reduce RF exposure by operating your cellular terminal efficiently by following the
below guidelines.
4.3.1.3 Efficient terminal operation
For your GSM terminal to operate at the lowest power level, consistent with satisfactory call quality:
• If your terminal has an extendible antenna, extend it fully. Some models allow you to place a
call with the antenna retracted. However your GSM terminal operates more efficiently with
the antenna fully extended.
• Do not hold the antenna when the terminal is « IN USE ». Holding the antenna affects call
quality and may cause the modem to operate at a higher power level than needed.
4.3.1.4 Modular Transmitter
Modular transmitter. This device is to be used only for mobile and fixed applications.
The antenna(s) used for this transmitter must be installed to provide a separation distance of
at least 20 cm from all persons and must not be co-located or operating in conjunction with
any other antenna or transmitter. The antenna(s) used for this transmitter must not exceed

a gain of 3 dBi for mobile operation and 7 dBi for fixed operation. Users and OEM
integrators must be provided with antenna installation instructions and transmitter operating
conditions for satisfying RF exposure compliance. OEM must also be provided with
labelling instructions. This device contains 900 MHz GSM functions that are not operational
in U.S. Territories. This filing is only applicable for GSM 850 MHz and 1900 MHz PCS
operations.
4.3.1.5 Antenna care and replacement
Do not use the GSM terminal with a damaged antenna. If a damaged antenna comes into contact
with the skin, a minor burn may result. Replace a damaged antenna immediately. Consult your
manual to see if you may change the antenna yourself. If so, use only a manufacturer-approved
antenna. Otherwise, have your antenna repaired by a qualified technician.
Use only the supplied or approved antenna. Unauthorized antennas, modifications or attachments
could damage the terminal and may contravene local RF emission regulations or invalidate type
approval.
4.3.2 General safety
4.3.2.1 Driving
Check the laws and the regulations regarding the use of cellular devices in the area where you have
to drive as you always have to comply with them. When using your GSM terminal while driving,
please:
• give full attention to driving,
• pull off the road and park before making or answering a call if driving conditions so require.
4.3.2.2 Electronic devices
Most electronic equipment, for example in hospitals and motor vehicles, is shielded from RF energy.
However RF energy may affect some improperly shielded electronic equipment.
4.3.2.3 Vehicle electronic equipment
Check your vehicle manufacturer representative to determine if any on-board electronic equipment
is adequately shielded from RF energy.
4.3.2.4 Medical electronic equipment
Consult the manufacturer of any personal medical devices (such as pacemakers, hearing aids,
etc...) to determine if they are adequately shielded from external RF energy.
Turn your terminal OFF in health care facilities when any regulations posted in the area instruct you
to do so. Hospitals or health care facilities may be using RF monitoring equipment.

4.3.2.5 Aircraft
Turn your terminal OFF before boarding any aircraft.
Use it on the ground only with crew permission.
Do not use it in the air.
To prevent possible interference with aircraft systems, Federal Aviation Administration (FAA)
regulations require you to have permission from a crew member to use your terminal while the
aircraft is on the ground. To prevent interference with cellular systems, local RF regulations prohibit
using your modem while airborne.
4.3.2.6 Children
Do not allow children to play with your GSM terminal. It is not a toy. Children could hurt themselves
or others (by poking themselves or others in the eye with the antenna, for example). Children could
damage the modem, or make calls that increase your modem bills.
4.3.2.7 Blasting areas
To avoid interfering with blasting operations, turn your unit OFF when in a « blasting area » or in
areas posted: « turn off two-way radio ». Construction crew often use remote control RF devices to
set off explosives.
4.3.2.8 Potentially explosive atmospheres
Turn your terminal OFF when in any area with a potentially explosive atmosphere. It is rare, but your
modem or its accessories could generate sparks. Sparks in such areas could cause an explosion or
fire resulting in bodily injuries or even death.
Areas with a potentially explosive atmosphere are often, but not always, clearly marked. They
include fuelling areas such as petrol stations; below decks on boats; fuel or chemical transfer or
storage facilities; and areas where the air contains chemicals or particles, such as grain, dust, or
metal powders.
Do not transport or store flammable gas, liquid, or explosives, in the compartment of your vehicle
which contains your terminal or accessories.
Before using your terminal in a vehicle powered by liquefied petroleum gas (such as propane or
butane) ensure that the vehicle complies with the relevant fire and safety regulations of the country
in which the vehicle is to be used.
