Consequently, it is subject to ESD handling precautions that typically apply to ESD sensitive components. Proper ESD handling and packaging procedures must be applied throughout the processing, handling and operation of any application that incorporates a MC75 module. Special ESD protection provided on MC75: Antenna interface: one spark discharge line (spark gap) SIM interface: clamp diodes for protection against overvoltage. The remaining ports of MC75 are not accessible to the user of the final product (since they are installed within the device) and therefore, are only protected according to the “Human Body Model” requirements. MC75 has been tested according to the EN 61000-4-2 standard. The measured values can be gathered from the following table. Table 17: Measured electrostatic values Specification / Requirements Contact discharge Air discharge ETSI EN 301 489-7 ESD at SIM port ± 4kV ± 8kV ESD at antenna port ± 4kV ± 8kV Human Body Model (Test conditions: 1.5 kΩ, 100 pF) ESD at USB interface ± 1kV ± 1kV ESD at SD card interface ± 1kV ± 1kV ESD at all other interfaces ± 1kV ± 1kV Note: Please note that the values may vary with the individual application design. For example, it matters whether or not the application platform is grounded over external devices like a computer or other equipment, such as the Siemens reference application described in Chapter 8.

MC75 Hardware Interface Description Strictly confidential / Draft s MC75_V00.190a Page 76 of 91 15.02.2005 6.2 Mounting MC75 to the Application Platform There are many ways to properly install MC75 in the host device. An efficient approach is to mount the MC75 PCB to a frame, plate, rack or chassis. Fasteners can be M2 screws plus suitable washers, circuit board spacers, or customized screws, clamps, or brackets. In addition, the board-to-board connection can also be utilized to achieve better support. To help you find appropriate spacers a list of selected screws and distance sleeves for 3mm stacking height can be found in Section 9.2. When using the two small holes take care that the screws are inserted with the screw head on the bottom of the MC75 PCB. Screws for the large holes can be inserted from top or bottom. For proper grounding it is strongly recommended to use large ground plane on the bottom of board in addition to the five GND pins of the board-to-board connector. The ground plane may also be used to attach cooling elements, e.g. a heat sink or thermally conductive tape. To prevent mechanical damage, be careful not to force, bend or twist the module. Be sure it is positioned flat against the host device. All the information you need to install an antenna is summarized in Chapter 4. Note that the antenna pad on the bottom of the MC75 PCB must not be influenced by any other PCBs, components or by the housing of the host device. It needs to be surrounded by a restricted space as described in Section 4.1.

MC75 Hardware Interface Description Strictly confidential / Draft s MC75_V00.190a Page 80 of 91 15.02.2005 7 Sample Application Figure 39 shows a typical example of how to integrate a MC75 module into the GSM part of a mobile application. Usage of the various host interfaces depends on the desired features of the application. Audio interface 1 demonstrates the balanced connection of microphone and earpiece. This solution is particularly well suited for internal transducers. Audio interface 2 uses an unbalanced microphone and earpiece connection typically found in headset applications. The charging circuit is optimized for the charging stages (trickle charging and software controlled charging) as well as the battery and charger specifications described in Section 3.4. The PWR_IND line is an open collector that needs an external pull-up resistor which connects to the voltage supply of the microcontroller VCC µC. Low state of the open collector pulls the PWR_IND signal low and indicates that the MC75 module is active, high level notifies the Power-down mode. If the module is in Power-down mode avoid current flowing from any other source into the module circuit, for example reverse current from high state external control lines. Therefore, the controlling application must be designed to prevent reverse or return flow. This is not necessary for the USB interface. The SD memory card interface can be powered from an external supply or via the VEXT line of MC75. Figure 39 uses the VEXT line. The advantage of this solution is that when the module enters the Power-down mode, the SD memory card interface is shut down as well. If you prefer to connect an SD card to an external power supply, take care that the interface is shut down when the PWR_IND signal goes high in Power-down mode. The same applies to the I2C interface. The EMC measures are best practice recommendations. In fact, an adequate EMC strategy for an individual application is very much determined by the overall layout and, especially, the position of components. For example, mounting the internal acoustic transducers directly on the PCB eliminates the need to use the ferrite beads shown in the sample schematic. However, when connecting cables to the module’s interfaces it is strongly recommended to add appropriate ferrite beads for reducing RF radiation. Disclaimer No warranty, either stated or implied, is provided on the sample schematic diagram shown in Figure 39 and the information detailed in this section. As functionality and compliance with national regulations depend to a great amount on the used electronic components and the individual application layout manufacturers are required to ensure adequate design and operating safeguards for their products using MC75 modules.
