The SMT application interface incorporates the various application interfaces as well as the RF antenna interface. 2.1 Application Interface USB Interface 2.1.1 EHS5-E/EHS5-US supports a USB 2.0 High Speed (480Mbit/s) device interface that is Full Speed (12Mbit/s) compliant. The USB interface is primarily intended for use as command and data interface and for downloading firmware. The USB host is responsible for supplying the VUSB_IN line. This line is for voltage detection only. The USB part (driver and transceiver) is supplied by means of BATT+. This is because EHS5-E/EHS5-US is designed as a self-powered device compliant with the Universal Serial Bus Specification Revision 2.01. Module VREG (3V075) lin. reg.

GND VUSB_IN USB_DP2) USB_DN2) RING0 1) All serial (including RS) and pull-up resistors for data lines are implemented. 2) If the USB interface is operated in High Speed mode (480MHz), it is recommended to take special care routing the data lines USB_DP and USB_DN. Application layout should in this case implement a differential impedance of 90Ohm for proper signal integrity. Figure 2: USB circuit To properly connect the module's USB interface to the host a USB 2.0 compatible connector is required. Furthermore, the USB modem driver distributed with EHS5-E/EHS5-US needs to be installed. 1. The specification is ready for download on http://www.usb.org/developers/docs/

EHS5_HIO_v01.000 Confidential / Preliminary Page 10 of 35 2012-11-14 EHS5-E/EHS5-US Hardware Interface Overview 2.1 Application Interface 18 While the USB connection is active, the module will not change into SLEEP Mode. To enable switching into SLEEP mode the USB host must bring its USB interface into Suspend state. Al-

so, VUSB_IN should always be kept enabled for this functionality. See Universal Serial Bus Specification Revision 2.01 for a description of the Suspend state. On incoming calls EHS5-E/

EHS5-US will then generate a remote wake up request to resume the USB connection (active low). As an alternative to the regular USB remote wakeup mechanism it is possible to employ the RING0 line to wake up the host application. The benefit is that the RING0 line can wake up the host application in case of incoming calls or other events signalized by URCs while the USB interface is suspended or shut down. 2.1.2 Serial Interface ASC0 EHS5-E/EHS5-US offers an 8-wire unbalanced, asynchronous modem interface ASC0 con-

forming to ITU-T V.24 protocol DCE signalling. The electrical characteristics do not comply with ITU-T V.28. The significant levels are 0V (for low data bit or active state) and 1.8V (for high data bit or inactive state). EHS5-E/EHS5-US is designed for use as a DCE. Based on the conventions for DCE-DTE con-

nections it communicates with the customer application (DTE) using the following signals:

Port TXD @ application sends data to the modules TXD0 signal line Port RXD @ application receives data from the modules RXD0 signal line Figure 3: Serial interface ASC0 Features:

Includes the data lines TXD0 and RXD0, the status lines RTS0 and CTS0 and, in addition, the modem control lines DTR0, DSR0, DCD0 and RING0. ASC0 is designed for controlling GSM/UMTS voice calls, transferring data and for control-

ling the module with AT commands. Full multiplexing capability allows the interface to be partitioned into virtual channels. EHS5_HIO_v01.000 Confidential / Preliminary Page 11 of 35 2012-11-14 EHS5-E/EHS5-US Hardware Interface Overview 2.1 Application Interface 18 The RING0 signal serves to indicate incoming calls and other types of URCs (Unsolicited Result Code). It can also be used to send pulses to the host application, for example to wake up the application from power saving state. Configured for 8 data bits, no parity and 1 stop bit. ASC0 can be operated at fixed bit rates from 1200bps up to 921600bps. Autobauding supports bit rates from 1200bps up to 230400bps. Supports RTS0/CTS0 hardware flow control. Wake up from SLEEP mode by RTS0 activation (high to low transition). 2.1.3 Serial Interface ASC1 EHS5-E/EHS5-US offers a 4-wire unbalanced, asynchronous modem interface ASC1 conform-

ing to ITU-T V.24 protocol DCE signalling. The electrical characteristics do not comply with ITU-

T V.28. The significant levels are 0V (for low data bit or active state) and 1.8V (for high data bit or inactive state). EHS5-E/EHS5-US is designed for use as a DCE. Based on the conventions for DCE-DTE con-

nections it communicates with the customer application (DTE) using the following signals:

Port TXD @ application sends data to modules TXD1 signal line Port RXD @ application receives data from the modules RXD1 signal line Figure 4: Serial interface ASC1 Features Includes only the data lines TXD1 and RXD1 plus RTS1 and CTS1 for hardware hand-

shake. On ASC1 no RING line is available. Configured for 8 data bits, no parity and 1 or 2 stop bits. ASC1 can be operated at fixed bit rates from 1,200 bps to 921600 bps. Autobauding is not supported on ASC1. Supports RTS1/CTS1 hardware flow. EHS5_HIO_v01.000 Confidential / Preliminary Page 12 of 35 2012-11-14 EHS5-E/EHS5-US Hardware Interface Overview 2.1 Application Interface 18 2.1.4 UICC/SIM/USIM Interface EHS5-E/EHS5-US has an integrated UICC/SIM/USIM interface compatible with the 3GPP 31.102 and ETSI 102 221. This is wired to the host interface in order to be connected to an external SIM card holder. Five pads on the SMT application interface are reserved for the SIM interface. The UICC/SIM/USIM interface supports 3V and 1.8V SIM cards. The CCIN signal serves to detect whether a tray (with SIM card) is present in the card holder. Using the CCIN signal is mandatory for compliance with the GSM 11.11 recommendation if the mechanical design of the host application allows the user to remove the SIM card during oper-

ation. To take advantage of this feature, an appropriate SIM card detect switch is required on the card holder. For example, this is true for the model supplied by Molex, which has been test-

ed to operate with EHS5-E/EHS5-US and is part of the Cinterion reference equipment submit-

ted for type approval. See Section 7.1 for Molex ordering numbers. Description Separate ground connection for SIM card to improve EMC. Chipcard clock Table 1: Signals of the SIM interface (SMT application interface) Signal GND CCCLK CCVCC SIM supply voltage. CCIO CCRST CCIN Serial data line, input and output. Chipcard reset Input on the baseband processor for detecting a SIM card tray in the holder. If the SIM is removed during operation the SIM interface is shut down immediately to prevent destruc-

tion of the SIM. The CCIN signal is active low. The CCIN signal is mandatory for applications that allow the user to remove the SIM card during operation. The CCIN signal is solely intended for use with a SIM card. It must not be used for any other purposes. Failure to comply with this requirement may invalidate the type approval of EHS5-E/EHS5-US. Note: No guarantee can be given, nor any liability accepted, if loss of data is encountered after removing the SIM card during operation. Also, no guarantee can be given for properly initializ-

ing any SIM card that the user inserts after having removed the SIM card during operation. In this case, the application must restart EHS5-E/EHS5-US. EHS5_HIO_v01.000 Confidential / Preliminary Page 13 of 35 2012-11-14 EHS5-E/EHS5-US Hardware Interface Overview 2.1 Application Interface 18 The figure below shows a circuit to connect an external SIM card holder. V180 CCIN CCVCC CCRST CCIO CCCLK SIM 220nF 1nF Figure 5: External UICC/SIM/USIM card holder circuit The total cable length between the SMT application interface pads on EHS5-E/EHS5-US and the pads of the external SIM card holder must not exceed 100mm in order to meet the specifi-

cations of 3GPP TS 51.010-1 and to satisfy the requirements of EMC compliance. To avoid possible cross-talk from the CCCLK signal to the CCIO signal be careful that both lines are not placed closely next to each other. A useful approach is using a GND line to shield the CCIO line from the CCCLK line. 2.1.5 Digital Audio Interface EHS5-E/EHS5-USs digital audio interface (DAI) can be used to connect audio devices capable of pulse code modulation (PCM). GPIO Interface 2.1.6 EHS5-E/EHS5-US offers a GPIO interface with 4 GPIO lines1. The GPIO lines are shared with other interfaces: Status LED (see Section 2.1.9) or the PWM functionality (see Section 2.1.8). The following table shows the configuration variants of the GPIO pads. All variants are mutually exclusive, i.e. a pad configured as GPIO is locked for alternative use. 1. The GPIO functionality will be available as of Release 2. EHS5_HIO_v01.000 Confidential / Preliminary Page 14 of 35 2012-11-14 EHS5-E/EHS5-US Hardware Interface Overview 2.1 Application Interface 18 Table 2: GPIO assignment GPIO GPIO5 GPIO6 GPIO7 GPIO8 PWM PWM2 PWM1 Status LED Status LED When the EHS5-E/EHS5-US starts up, all GPIO lines are set to high-impedance state after ini-

tializing. Therefore, it is recommended to connect external pull-up or pull-down resistors to all GPIO lines you want to use as output. This is necessary to keep these lines from floating or driving any external devices. I2C Interface 2.1.7 I2C is a serial, 8-bit oriented data transfer bus for bit rates up to 400kbps in Fast mode1. It con-

sists of two lines, the serial data line I2CDAT and the serial clock line I2CCLK. The module acts as a single master device, e.g. the clock I2CCLK is driven by the module. I2CDAT is a bi-direc-

tional line. Each device connected to the bus is software addressable by a unique 7-bit ad-

dress, and simple master/slave relationships exist at all times. The module operates as master-

transmitter or as master-receiver. The customer application transmits or receives data only on request of the module. The I2C interface can be powered via the V180 line of EHS5-E/EHS5-US. If connected to the V180 line, the I2C interface will properly shut down when the module enters the Power Down mode. Note: Good care should be taken when creating the PCB layout of the host application: The traces of I2CCLK and I2CDAT should be equal in length and as short as possible. PWM Interfaces 2.1.8 EHS5-E/EHS5-US offers two PWM (Pulse Width Modulation) interfaces, which can be used, for example, to connect buzzers. The PWM1 line is shared with GPIO7 and the PWM2 line is shared with GPIO6 (for GPIOs see Section 2.1.6). GPIO and PWM functionality are mutually exclusive. 2.1.9 Status LED The GPIO5 line at the SMT application interface can be configured to drive a status LED which indicates different operating modes of the module (for GPIOs see Section 2.1.6). GPIO and LED functionality are mutually exclusive. 1. The I2C functionality will be available as of Release 2. EHS5_HIO_v01.000 Confidential / Preliminary Page 15 of 35 2012-11-14 EHS5-E/EHS5-US Hardware Interface Overview 2.2 RF Antenna Interface 18 2.2 RF Antenna Interface The RF interface has an impedance of 50. EHS5-E/EHS5-US is capable of sustaining a total mismatch at the antenna line without any damage, even when transmitting at maximum RF power. The external antenna must be matched properly to achieve best performance regarding radi-

ated power, modulation accuracy and harmonic suppression. Antenna matching networks are not included on the EHS5-E/EHS5-US module and should be placed in the host application if the antenna does not have an impedance of 50. Regarding the return loss EHS5-E/EHS5-US provides the following values in the active band:

Table 3: Return loss in the active band State of module Receive Transmit Return loss of module

> 8dB not applicable Recommended return loss of application

> 12dB

> 12dB Antenna Installation 2.2.1 The antenna is connected by soldering the antenna pad and its neighboring ground pads di-

rectly to the applications PCB. The antenna pad is the antenna reference point (ARP) for EHS5-E/EHS5-US. All RF data specified throughout this document is related to the ARP. The distance between the antenna pad and its neighboring GND pads has been optimized for best possible impedance. On the application PCB, special attention should be paid to these pads, in order to prevent mismatch. The wiring of the antenna connection line, starting from the antenna pad to the application an-

tenna should result in a 50 line impedance. Line width and distance to the GND plane needs to be optimized with regard to the PCBs layer stack. To prevent receiver desensitization due to interferences generated by fast transients like high speed clocks on the application PCB, it is recommended to realize the antenna connection line using embedded Stripline rather than Micro-Stripline technology. For type approval purposes, the use of a 50 coaxial antenna connector (U.FL-R-SMT) might be necessary. In this case the U.FL-R-SMT connector should be placed as close as possible to EHS5-E/EHS5-USs antenna pad. EHS5_HIO_v01.000 Confidential / Preliminary Page 16 of 35 2012-11-14 EHS5-E/EHS5-US Hardware Interface Overview 2.3 Sample Application 18 2.3 Sample Application Figure 6 shows a typical example of how to integrate a EHS5-E/EHS5-US module with an ap-

plication. Usage of the various host interfaces depends on the desired features of the applica-

tion. Because of the very low power consumption design, current flowing from any other source into the module circuit must be avoided, for example reverse current from high state external control lines. Therefore, the controlling application must be designed to prevent reverse current flow. Otherwise there is the risk of undefined states of the module during startup and shutdown or even of damaging the module. Because of the high RF field density inside the module, it cannot be guaranteed that no self interference might occur, depending on frequency and the applications grounding concept. ex-

cluded that in some applications dependant on the grounding concept of the customer. The po-

tential interferers may be minimized by placing small capacitors (47pF) at suspected lines (e.g. RXD0, RXT0, VDDLP, and ON). While developing SMT applications it is strongly recommended to provide test points for certain signals resp. lines to and from the module - for debug and/or test purposes. The SMT application should allow for an easy access to these signals. For details on how to implement test points see [3]. 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 po-

sition 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. Please note that EHS5-E/EHS5-US is not intended for use with cables longer than 3m. Disclaimer No warranty, either stated or implied, is provided on the sample schematic diagram shown in Figure 6 and the information detailed in this section. As functionality and compliance with na-

tional regulations depend to a great amount on the used electronic components and the indi-

vidual application layout manufacturers are required to ensure adequate design and operating safeguards for their products using EHS5-E/EHS5-US modules.

Manufac-

turers of the cellular terminal are advised to convey the following safety information to users and operating personnel and to incorporate these guidelines into all manuals supplied with the product. Failure to comply with these precautions violates safety standards of design, manu-

facture and intended use of the product. Cinterion Wireless Modules assumes no liability for customers failure to comply with these precautions. When in a hospital or other health care facility, observe the restrictions on the use of mobiles. Switch the cellular terminal or mobile off, if instructed to do so by the guide-

lines posted in sensitive areas. Medical equipment may be sensitive to RF energy. The operation of cardiac pacemakers, other implanted medical equipment and hear-

ing aids can be affected by interference from cellular terminals or mobiles placed close to the device. If in doubt about potential danger, contact the physician or the manufac-

turer of the device to verify that the equipment is properly shielded. Pacemaker patients are advised to keep their hand-held mobile away from the pacemaker, while it is on. Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it can-

not be switched on inadvertently. The operation of wireless appliances in an aircraft is forbidden to prevent interference with communications systems. Failure to observe these instructions may lead to the suspension or denial of cellular services to the offender, legal action, or both. Do not operate the cellular terminal or mobile in the presence of flammable gases or fumes. Switch off the cellular terminal when you are near petrol stations, fuel depots, chemical plants or where blasting operations are in progress. Operation of any elec-

trical equipment in potentially explosive atmospheres can constitute a safety hazard. Your cellular terminal or mobile receives and transmits radio frequency energy while switched on. Remember that interference can occur if it is used close to TV sets, radios, computers or inadequately shielded equipment. Follow any special regulations and always switch off the cellular terminal or mobile wherever forbidden, or when you suspect that it may cause interference or danger. Road safety comes first! Do not use a hand-held cellular terminal or mobile when driv-

ing a vehicle, unless it is securely mounted in a holder for speakerphone operation. Before making a call with a hand-held terminal or mobile, park the vehicle. Speakerphones must be installed by qualified personnel. Faulty installation or opera-

tion can constitute a safety hazard. IMPORTANT!

Cellular terminals or mobiles operate using radio signals and cellular networks. Because of this, connection cannot be guaranteed at all times under all conditions. Therefore, you should never rely solely upon any wireless device for essential com-

munications, for example emergency calls. Remember, in order to make or receive calls, the cellular terminal or mobile must be switched on and in a service area with adequate cellular signal strength. Some networks do not allow for emergency calls if certain network services or phone features are in use (e.g. lock functions, fixed dialing etc.). You may need to deactivate those features before you can make an emergency call. Some networks require that a valid SIM card be properly inserted in the cellular termi-

nal or mobile.
