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.

AAA TTT

This symbol is used to indicate the interfaces not available with AT commands.

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 (U 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.

Two different inputs are provided for the power supply:

• the second one, VDD is used to supply the baseband part.

Notes

:

• 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.

2.6 Keyboard interface

 Warning:

This interface is not FULLY available with AT commands:

An AT command allows to get the input key code (see AT+CMER command description). This code has then to be processed by the application.

This interface provides 10 connections:

• 5 rows (ROW0 to ROW4),

• 5 columns (COL0 to COL4).

The scanning is a digital one, and the debouncing is done in the WISMO module. No discrete components like R, C (Resistor, Capacitor) are needed.

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).

• When used, a low to high transition means that the SIM card is inserted and a high to low

transition means that the SIM card is removed.

2.9.2 SIM 3/5V management

1

The WISMO Quik Q24x6 sub-series module is designed to interface with 3 V SIMs only

.

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).

1

Most of the GSM operators have been providing 3 V SIMs since 1998.

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 handsfree 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 Speaker outputs

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).

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.

2.15.1 General description

This input is used to switch ON or OFF the WISMO module.

A high level signal has to be provided on the pin ON/~OFF to switch ON the module.

The level of the voltage of this signal has to be maintained between 2.4 V and VDD during a minimum of 1 s.

This signal can be left at high level until switch OFF.

To be able to switch OFF the module, the pin ON/~OFF has to be released. Through the firmware, the module can be switched OFF (using the AT+CPOF command).

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 application

This input can be used to download a software in the Flash memory of the WISMO module.

For the applications based on AT commands, this is a backup download procedure only (refer to document [1] Customer Design Guidelines).

The internal boot procedure is started when this pin is low during the reset of the module.

In normal mode this pin has to be left open. In Internal boot mode, low level has to be set through a 1KΩ resistor. If used, this input has to be driven by an open collector or an open drain output:

This signal is used to force a reset procedure by providing low level during at least 500 µs.

This signal has to be considered as an emergency reset only. A reset procedure is automatically driven by an internal hardware during the power-up sequence.

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:

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 terminal 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.

is based on the GSM standard for cellular technology. The GSM standard is

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.
