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).ELS31-US/ELS51-US is designed for use as a DCE. Based on the conventions for DCE-DTE connections it communicates with the customer application (DTE) using the following signals:• Port TXD @ application sends data to the module’s TXD0 signal line• Port RXD @ application receives data from the module’s RXD0 signal lineFigure 3: Serial interface ASC0Features:• 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.• Configured for 8 data bits, no parity and 1 stop bit. • ASC0 can be operated at fixed bit rates from 4800bps up to 921600bps.• Supports RTS0/CTS0 hardware flow control. Communication is possible by using only RXDand TXD lines, if RTS0 is pulled low. • Wake up from SLEEP mode by RTS0 activation. The ASC0 interface is dedicated to signaling via AT commands (3GPP standard 27.007 + mod-ule specific AT commands).

The electrical characteristics do not complywith ITU-T V.28. The significant levels are 0V (for low data bit or active state) and 1.8V (for highdata bit or inactive state). The ASC1 interface lines are originally available as GPIO lines. If configured as ASC1 lines, the GPIO lines are assigned as follows: GPIO16 --> RXD1, GPIO17 --> TXD1, GPIO18 --> RTS1 and GPIO19 --> CTS1. Configuration is done by AT command (see [1]: AT^SCFG). The configuration is non-volatile and becomes active after a module restart.ELS51-US is designed for use as a DCE.

Cinterion® ELS31-/ELS51-US Hardware Interface Overview2.1 Application Interface29ELS31-US_ELS51-US_HIO_v01.000a 2016-12-28Confidential / PreliminaryPage 14 of 462.1.4 UICC/SIM/USIM InterfaceELS31-US/ELS51-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. The CCIN signal must be connected to V180 for the detection to work on the module. Other-wise the SIM card can never be detected by the module.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 ELS31-US/ELS51-US and is part of the Gemalto M2M reference equipment submitted for type approval. See Section 7.1 for Molex ordering numbers.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 ELS31-US/ELS51-US.Table 1: Signals of the SIM interface (SMT application interface)Signal DescriptionGND Separate ground connection for SIM card to improve EMC.CCCLK Chipcard clockCCVCC SIM supply voltage.CCIO Serial data line, input and output.CCRST Chipcard resetCCIN 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 by default low and will change to high level if a SIM card is inserted.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 ELS31-US/ELS51-US.

A useful approach is using a GND line to shield the CCIO line from the CCCLK line.The ELS31-US/ELS51-US includes embedded ESD protection for the SIM interface that com-plies to ETSI EN 301 489-1/7: Contact discharge: ± 4kV, air discharge: ± 8kV.SIMCCVCCCCRSTCCIOCCCLK220nF1nFCCINV180

It consists of two lines,the serial data line I2CDAT and the serial clock line I2CCLK. The module acts as a single mas-ter device, e.g. the clock I2CCLK is driven by the module. I2CDAT is a bi-directional line. Eachdevice connected to the bus is software addressable by a unique 7-bit address, and simplemaster/slave relationships exist at all times. The module operates as master-transmitter or asmaster-receiver. The customer application transmits or receives data only on request of themodule.The I2C interface can be powered via the V180 line of ELS31-US/ELS51-US. If connected tothe V180 line, the I2C interface will properly shut down when the module enters the PowerDown mode.Note: Good care should be taken when creating the PCB layout of the host application: Thetraces of I2CCLK and I2CDAT should be equal in length and as short as possible.2.1.7 SPI InterfaceThe ELS31-US/ELS51-US GPIO interface lines can be configured as Serial Peripheral Inter-face (SPI). The SPI is a synchronous serial interface for control and data transfer betweenELS31-US/ELS51-US and the external application. Only one application can be connected tothe SPI and the interface supports only master mode. The transmission rates are up to 6.5Mbit/s. The SPI interface comprises the two data lines SPI_MOSI and SPI_MISO, the clock lineSPI_CLK a well as the chip select lines SPI_CS1 and SPI_CS2.2.1.8 Pulse CounterThe GPIO8 line can be configured as pulse counter line COUNTER (for GPIOs see Section2.1.5). The pulse counter interface can be used, for example, as a clock - it is designed to mea-sure signals from 0 to 1000 pulses per second. Note that the pulse counter works in batchesof 8 pulses, i.e., the URC indicates the number of pulses counted in batches of 8 pulses. Formore information on how to use this feature see [1].2.1.9 HSIC Interface (ELS51-US Only)The (USB) High Speed Inter Chip (HSIC) interface can be used between the module and an external application processor, and is compliant to the High Speed USB 2.0 interface with 480Mbit/s. The maximum distance between module processor and external application proces-sor should not exceed 100mm.The HSIC interface comprises two signal lines (strobe - HSIC_STRB - and data - HSIC_DATA) used in a source synchronous serial interface with a 240MHz clock to provide a 480Mbps USB interface. The HSIC_STRB and HSIC_DATA lines are high-speed signals and should be rout-ed as 50Ohm impedance traces. The trace length of these signals should be balanced to min-imize timing skew and be no longer than 100mm.The HSIC interface implementation complies with the USB HSIC standard “High-Speed Inter-Chip USB Electrical Specification”, Version 1, September 23, 20071.1. The USB specifications are ready for download on http://www.usb.org/developers/docs/usb20_docs/

LED and GPOfunctionality are mutually exclusive.2.1.11.2 Fast ShutdownThe GPIO4 interface line can be configured as fast shutdown signal line FST_SHDN. The con-figured FST_SHDN line is an active low control signal. If enabled, a low impulse of 10 millisec-onds on the FST_SHDN line starts the fast shutdown procedure.The fast shutdown procedure still finishes any data activities on the module‘s flash file system, thus ensuring data integrity, but the module will no longer deregister gracefully from the network.

ELS31-US/ELS51-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 ELS31-US/ELS51-US module and should be placed in the host application if the antenna does not have an impedance of 50Ω.Regarding the return loss ELS31-US/ELS51-US provides the following values in the active band:Table 5: Return loss in the active bandState of module Return loss of module Recommended return loss of applicationReceive > 8dB > 12dBTransmit not applicable > 12dB

The antenna pad is the antenna reference point (ARP) for ELS31-US/ELS51-US. All RF data specified throughout this document is related to the ARP.The distance between the antenna RF pads and its neighboring GND pads has been optimized for best possible impedance. On the application PCB, special attention should be paid to these 3 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 50Ω line impedance. Line width and distance to the GND plane needs to be optimized with regard to the PCB’s layer stack. Some examples are given in Section 2.2.2.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. Please see Section 2.2.2.2 for an example.For type approval purposes, the use of a 50Ω 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 ELS31-US/ELS51-US‘s antenna pad.

Cinterion® ELS31-/ELS51-US Hardware Interface Overview2.3 Sample Application29ELS31-US_ELS51-US_HIO_v01.000a 2016-12-28Confidential / PreliminaryPage 28 of 462.3 Sample ApplicationFigure 12 shows a typical example of how to integrate a ELS31-US/ELS51-US module with anapplication. Usage of the various host interfaces depends on the desired features of the appli-cation.Because of the high RF field density inside the module, it cannot be guaranteed that no selfinterference might occur, depending on frequency and the applications grounding concept. Thepotential interferers may be minimized by placing small capacitors (47pF) at suspected lines(e.g. RXD0, or ON). While developing SMT applications it is strongly recommended to provide test pointsfor certain signals, i.e., 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 onhow to implement test points see [4].The EMC measures are best practice recommendations. In fact, an adequate EMC strategy foran 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 thePCB eliminates the need to use the ferrite beads shown in the sample schematic. Note: ELS31-US/ELS51-US is not intended for use with cables longer than 3m.DisclaimerNo warranty, either stated or implied, is provided on the sample schematic diagram shown inFigure 12 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 operatingsafeguards for their products using ELS31-US/ELS51-US modules.

There are two separate voltage domains for BATT:• BATT_BB with a line mainly for the baseband power supply.• BATT_RF with a line for the RF power amplifier supply.Please note that throughout the document BATT refers to both voltage domains and powersupply lines - BATT_BB and BATT_RF.The power supply of ELS31-US/ELS51-US has to be a single voltage source at BATT_BB andBATT_RF. It must be able to provide the current for all operation modes of the module. All the key functions for supplying power to the device are handled by the power managementsection of the analog controller. This IC provides the following features:• Stabilizes the supply voltages for the baseband using low drop linear voltage regulators anda DC-DC step down switching regulator.• Switches the module's power voltages for the power-up and -down procedures.• SIM switch to provide SIM power supply.Table 6: Overview of operating modesMode FunctionNormal opera-tionLTE IDLE No data transfer is in progress and the USB connection is suspended by host (or is not present) and no active communication via ASC0/ASC1.

Cinterion® ELS31-/ELS51-US Hardware Interface Overview6.4 Safety Precaution Notes43ELS31-US_ELS51-US_HIO_v01.000a 2016-12-28Confidential / PreliminaryPage 43 of 466.4 Safety Precaution NotesThe following safety precautions must be observed during all phases of the operation, usage, service or repair of any cellular terminal or mobile incorporating ELS31-US/ELS51-US. Manu-facturers 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. Gemalto M2M assumes no liability for customer’s fail-ure 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.).
