2 Interface Characteristics

EMS31-US is equipped with an SMT application interface that connects to the external appli­cation. The SMT application interface incorporates the various application interfaces as well as
the RF antenna interfaces.

2.1 Application Interface

2.1.1 Serial Interface ASC0

EMS31-US offers an 8-wire unbalanced, asynchronous modem interface ASC0 conforming to
ITU-T V.28 protocol DCE signaling. 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).

EMS31-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 line

Figure 2: 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.

• Configured for 8 data bits, no parity and 1 stop bit.

• ASC0 can be operated at fixed bit rates from 1,200bps up to 3,686,400bps.

• Autobauding (supported by future firmware version)

• Supports RTS0/CTS0 hardware flow control. Communication is possible by using only RXD
and TXD lines, if RTS0 is pulled low.

2.1.2 Serial Interface ASC1

EMS31-US provides a 4-wire unbalanced, asynchronous modem interface ASC1 conforming
to ITU-T V.24 protocol DCE signaling. 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).

EMS31-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 module’s TXD1 signal line

• Port RXD @ application receives data from the module’s RXD1 signal line

Figure 3: Serial interface ASC1

Features

• Includes only the data lines TXD1 and RXD1 plus RTS1 and CTS1 for hardware hand­shake.

• 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 3,686,400bps.

• Supports RTS1/CTS1 hardware flow control. Communication is possible by using only RXD
and TXD lines, if RTS1 is pulled low.

2.1.3 UICC/SIM/USIM Interface

EMS31-US has two identical integrated UICC/SIM/USIM interfaces compatible with the 3GPP

31.102 and ETSI 102 221. These two interfaces are mutually exclusive, meaning that only one

UICC/SIM/USIM interface can be used at a time. This interface 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 each SIM interface.

The UICC/SIM/USIM interface supports 3V and 1.8V SIM cards.

The CCINx signal serves to detect whether a tray (with SIM card) is present in the card holder.
The CCINx signal must be connected to V180 for the detection to work on the module. Other­wise the SIM card can never be detected by the module.

Using the CCINx 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
operation. 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
tested to operate with EMS31-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 initializ­ing any SIM card that the user inserts after having removed the SIM card during operation. In
this case, the application must restart EMS31-US.

Table 1: Signals of the SIM interface (SMT application interface)

Signal Description

GND Separate ground connection for SIM card to improve EMC.

CCCLKx Chipcard clock

CCVCCx SIM supply voltage.

CCIOx Serial data line, input and output.

CCRSTx Chipcard reset

CCINx 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 destruc­tion of the SIM. The CCINx signal is by default low and will change to high level if a SIM
card is inserted.
The CCINx signal is mandatory for applications that allow the user to remove the SIM card
during operation.
The CCINx 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
EMS31-US.
Pull-down 220k resistor is mandatory.

The figure below shows a circuit to connect an external SIM card holder.

Figure 4: External UICC/SIM/USIM card holder circuit

The total cable length between the SMT application interface pads on EMS31-US and the pads
of the external SIM card holder must not exceed 100mm in order to meet the specifications of
3GPP TS 51.010-1 and to satisfy the requirements of EMC compliance.

To avoid possible cross-talk from the CCCLKx signal to the CCIOx 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 CCIOx line from the CCCLKx line.

2.1.4 GPIO Interface

EMS31-US offers a GPIO interface with 20 GPIO lines. The lines are shared with other inter­faces or functions: ASC0 (see Section 2.1.1), ASC1 (see Section 2.1.2),

The following table shows the configuration variants for the GPIO pads. All variants are mutu­ally exclusive, i.e. a pad configured for instance as ASC0 is locked for alternative usage.

*) Note: The following features are not yet available with the current product release: GPIO, I2C, Pulse

Counter, PWM, FST_SHDN and SPI.

After startup, the above mentioned alternative GPIO line assignments can be configured using
AT commands (see [1]). The configuration is non-volatile and available after module restart.

Note that this feature is not available with release 1.

The LED line can also be configured as GPO5 line, and can be used to drive a status LED that
indicates different operating modes of the module (for GPOs see Section 2.1.4). LED and
GPIO5 functionality are mutually exclusive.

2.2 RF Antenna Interface

The RF interface has an impedance of 50Ω. EMS31-US is capable of sustaining a 10:1 voltage
standing wave ratio (VSWR) 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 radi­ated power, modulation accuracy and harmonic suppression. Antenna matching networks are
not included on the EMS31-US module and should be placed in the host application if the an­tenna does not have an impedance of 50

Ω.

Regarding the return loss EMS31-US provides the following values in the active band:

2.2.1 Antenna Installation

The antenna is connected by soldering the antenna pad (RF_OUT, pad #59) its neighboring
ground pads (GND, i.e., pads #58 and #60) directly to the application's PCB. The antenna pad
is the antenna reference point (ARP) for EMS31-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 an­tenna should result in a 50

Ω line impedance. Line width and distance to the GND plane needs

to be optimized with regard to the PCB’s 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 Microstrip line technology.

For type approval purposes an external application must connect the RF signal in one of the
following ways:

•Via 50

Ω coaxial antenna connector (common connectors are U-FL or SMA) placed as close

as possible to the module's antenna pad.

• By soldering the antenna to the antenna connection line on the application’s PCB (without
the use of any connector) as close as possible to the module’s antenna pad.

• By routing the application PCB's antenna to the module’s antenna pad in the shortest way.

In case FCC certification of application using EMS31-US is required, the implementation of the
connection between module's antenna pad and antenna has to be designed similar to the im­plementation of this connection on evaluation board and according to KDB 996369 related to
modular approval requirements.

2.3 Sample Application

Page 16 of 33

2.3 Sample Application

Figure 5 shows a typical example of how to integrate an EMS31-US module with an application.

Usage of the various host interfaces depends on the desired features of the application.

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. The
potential 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 points
for 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 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 po­sition of components.

Note: EMS31-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 5 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 EMS31-US module.

3 Operating Characteristics

3.1 Operating Modes

The table below briefly summarizes the various operating modes referred to throughout the
document.

3.2 Power Supply

The power supply of EMS31-US has to be a single voltage source at BATT+. 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 management
section of the analog controller. This IC provides the following features:

• Stabilizes the supply voltages for the baseband using low drop linear voltage regulators and
a 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 4: Overview of operating modes

Mode Function

Normal
opera­tion

Active TX LTE data transfer in progress. Power consumption depends on network

settings, data transfer rate and radio conditions.
No data transfer is in progress and no active communication via ASC0/
ASC1.

IDLE No data transfer is in progress. The LTE part of the device can be in

LTE DRX, LTE eDRX or LTE PSM mode. Activity on ASC0 /ASC1 inter­faces can be present. Power consumption depends on the LTE power
saving mode and its parameters and on the activity on the ASC inter­faces.

Sleep The module is in low power consumption state. There is no activity inside the module but

module preserves the state in which it was before entering the sleep mode, including the
electrical states of the GPIOs. The module will enter sleep state only when the LTE part of
the module is in LTE DRX, LTE eDRX or LTE PSM mode or if it is in airplane mode. To
allow sleep mode the host application shall indicate via RTS lines that it has no intention to
send data.

Page 23 of 33

5.2 SAR requirements specific to portable mobiles

Mobile phones, PDAs or other portable transmitters and receivers incorporating a GSM module
must be in accordance with the guidelines for human exposure to radio frequency energy. This
requires the Specific Absorption Rate (SAR) of portable EMS31-US based applications to be
evaluated and approved for compliance with national and/or international regulations.

Since the SAR value varies significantly with the individual product design manufacturers are
advised to submit their product for approval if designed for portable use. For US markets the
relevant directives are mentioned below. It is the responsibility of the manufacturer of the final
product to verify whether or not further standards, recommendations or directives are in force
outside these areas.

Products intended for sale on US markets

ES 59005/ANSI C95.1 Considerations for evaluation of human exposure to Electromagnetic

Fields (EMFs) from Mobile Telecommunication Equipment (MTE) in the
frequency range 30MHz - 6GHz

Please note that SAR requirements are specific only for portable devices and not for mobile
devices as defined below:

• Portable device:
A portable device is defined as a transmitting device designed to be used so that the radi­ating structure(s) of the device is/are within 20 centimeters of the body of the user.

• Mobile device:
A mobile device is defined as a transmitting device designed to be used in other than fixed
locations and to generally be used in such a way that a separation distance of at least 20
centimeters is normally maintained between the transmitter's radiating structure(s) and the
body of the user or nearby persons. In this context, the term ''fixed location'' means that the
device is physically secured at one location and is not able to be easily moved to another
location.

6.4 Safety Precaution Notes

The following safety precautions must be observed during all phases of the operation, usage,
service or repair of any cellular terminal or mobile incorporating EMS31-US. Manufacturers 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, manufacture and
intended use of the product. Gemalto M2M assumes no liability for customer’s 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 guide­lines posted in sensitive areas. Medical equipment may be sensitive to RF energy.
The operation of cardiac pacemakers, other implanted medical equipment and hear­ing 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 manufac­turer 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 can­not 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 elec­trical 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 driv­ing 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 opera­tion 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 com­munications, 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 termi­nal or mobile.
