January 2001/ version 1.4 WMOi3 Integrated Modem 50 49 2 1 figure 4 : pin numbering/bottom view 4.1.2 Power supply The main power supply is provided through a double connection. These connections are respectively the pin 3 and 4 for the +5V and the pins 1 and 2 for the ground (GND). The pins 6, 21, 24 and 40 are also ground connection in order to produce a proper ground plane. A 5V +/-5% - 1A power is strictly required to supply the modem. Otherwise, serious dysfunctions may appear.

See the diagram below.
January 2001/ version 1.4 WMOi3 Integrated Modem 4.1.5 BOOT This input is used to switch the WMOi3 into download mode (backup procedure). The internal boot procedure is started when this pin is low during the power ON of the module. In normal mode, this pin has to be left open. If used, this input has to be driven by an open collector or an open drain. See below an example of application diagram.
January 2001/ version 1.4 WMOi3 Integrated Modem 4.1.6 Reset signal (~RST) This signal is used to force a reset of the WMOi3. It has to be used by providing low level during approximately 2ms. This signal has to be considered as an emergency reset only. A reset procedure is already driven by an internal hardware during the power-up sequence. This signal can also be used to provide a reset to an external device. If no external reset is necessary this input can be left open.

January 2001/ version 1.4 WMOi3 Integrated Modem 4.1.10 Audio Interface Two different microphone inputs and two different speaker outputs are supported. 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 recommended. 4.1.10.1 Microphone 2 Inputs The MIC2 inputs are differential ones. They already include the convenient biasing for an electret microphone (0,5 mA and 2 Volts).
January 2001/ version 1.4 WMOi3 Integrated Modem 4.1.10.2 Microphone 1 Inputs The MIC1 inputs are differential and do not include internal bias. To use these inputs with an electret microphone, bias has to be generated outside the WMOI3 modem according to the characteristic of this electret microphone. These inputs are the standard ones used for an external headset or a handsfree kit.

January 2001/ version 1.4 WMOi3 Integrated Modem 4.1.10.4 Speaker 1 Outputs Speaker outputs SPK1 are push-pull amplifiers and can be loaded down to 50 Ohms and up to 1nF. These outputs are differential and the output power can be adjusted by step of 2dB. The output can be directly connected to a speaker. When using a single-ended connection, be sure to have a very good ground plane, a very good filtering as well as a shielding in order to avoid any disturbance on the audio path.
January 2001/ version 1.4 WMOi3 Integrated Modem 4.1.11 SIM interface The external SIM interface is available through the 50-pin connector in order to use a stand-alone SIM card holder. This interface is 3V only on the engineering samples. 5V SIMs can be driven with production unit using an external level shifter. SIM line must not exceed 15 cm. see also “General guidelines” chapter 8 5 signals are available: SIMVCC: SIM power supply. SIMRST: reset. SIMCLK: clock. SIMDATA: I/O port.

January 2001/ version 1.4 WMOi3 Integrated Modem 4.2 RF Interface The impedance is 50 Ohms nominal. 4.2.1 RF connector The RF connector is MMCX (Miniature Micro Connector) standard type. An antenna can be directly connected through the matting connector or using a small adaptor. See also paragraph on GSM antenna. 4.2.2 RF performances RF performances are compliant with the ETSI recommendation 05.05 and 11.10.
January 2001/ version 1.4 WMOi3 Integrated Modem 5 Connector Supplier and Peripheral devices 5.1 Where to find the SMD connectors The WMOi3 matting interface connector is made by SAMTEC France (http://www.samtec.com/). Many SAMTEC products are available via SAMTEC dealers throughout the world. The connectors data sheets are available in annex of this document.
January 2001/ version 1.4 WMOi3 Integrated Modem 5.1.1 GSM Antenna The integrated modem antenna connector is a MMCX connector. The MMCX connector incorporates a 'Snap On' latching action in order to make the connection easier with an excellent RF performance. An additional advantage is its small physical size which is 50% of the standard MCX connector. This type of connector is suitable for the standard ranges of flexible and semi-rigid cables.
January 2001/ version 1.4 WMOi3 Integrated Modem 5.1.2 The SIM card holder The SIM card holder used in the integrated modem is a MOLEX connector. Part number connector: 99228-0002 Part number holder : 91236-0002 For more information about this connector : http://www.molex.com/ It is possible to use a stand-alone SIM card holder through the 50-pin connector (the length of the SIM line must not exceed 15 cm).

January 2001/ version 1.4 WMOi3 Integrated Modem 8 General guidelines for the use of the WMOi3 8.1 Key information 8.1.1 Hardware and RF • • • • • • Ground plane: Wavecom recommends to have a common ground plane for analog, digital and RF grounds. Length of the SIM interface lines (15 cm maximum) Bias of the Microphone inputs must be properly adjusted when using audio connectors (mic + speaker) 1.
January 2001/ version 1.4 WMOi3 Integrated Modem 8.1.3.2 backup procedure In case the nominal upgrade mode is not possible (due to critical corruption on the flash memory), a backup procedure is also available. It requires a WAVECOM specific software to download the firmware file into the modem. This tool has to run on a PC connected to the serial bus of the modem. As this procedure is very specific and needs Wavecom tools, this process has to be executed by your distributor.
