2.1.3 USB Interface
ELS61-AUS 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 external application is responsible for supplying the VUSB_IN line. This line is used for cable detection only. The USB part (driver and transceiver) is supplied by means of BATT+. This
is because ELS61-AUS is designed as a self-powered device compliant with the “Universal Serial Bus Specification Revision 2.0”
1
.
Figure 5: USB circuit
To properly connect the module's USB interface to the external application, a USB 2.0 compatible connector and cable or hardware design is required. For more information on the USB related signals see Table 2. Furthermore, the USB modem driver distributed with ELS61-AUS
needs to be installed.

2.1.3.1 Reducing Power Consumption
While a USB connection is active, the module will never switch into SLEEP mode. Only if the
USB interface is in Suspended state or Detached (i.e., VUSB_IN = 0) is the module able to
switch into SLEEP mode thereby saving power. There are two possibilities to enable power reduction mechanisms:
• Recommended implementation of USB Suspend/Resume/Remote Wakeup:
The USB host should be able to bring its USB interface into the Suspended state as
described in the “Universal Serial Bus Specification Revision 2.0“
work, the VUSB_IN line should always be kept enabled. On incoming calls and other events
ELS61-AUS will then generate a Remote Wakeup request to resume the USB host controller.
See also [5] (USB Specification Revision 2.0, Section 10.2.7, p.282):
"If USB System wishes to place the bus in the Suspended state, it commands the Host Controller to stop all bus traffic, including SOFs. This causes all USB devices to enter the Suspended state. In this state, the USB System may enable the Host Controller to respond to
bus wakeup events. This allows the Host Controller to respond to bus wakeup signaling to
restart the host system."

. For this functionality to
• Implementation for legacy USB applications not supporting USB Suspend/Resume:
As an alternative to the regular USB suspend and resume mechanism it is possible to
employ the RING0 line to wake up the host application in case of incoming calls or events
signalized by URCs while the USB interface is in Detached state (i.e., VUSB_IN = 0). Every
wakeup event will force a new USB enumeration. Therefore, the external application has to
carefully consider the enumeration timings to avoid loosing any signalled events. For details
on this host wakeup functionality see Section 2.1.13.3. To prevent existing data call connections from being disconnected while the USB interface is in detached state (i.e., VUSB_IN=0) it is possible to call AT&D0, thus ignoring the status of the DTR line (see also [1]).

2.1.4 Serial Interface ASC0
ELS61-AUS offers an 8-wire unbalanced, asynchronous modem interface ASC0 conforming 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). For electrical characteristics please refer to Table 2. For an illustration of the
interface line’s startup behavior see Figure 7.
ELS61-AUS 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 6: 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.
• 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 1,200bps up to 921,600bps.
• Autobauding supports bit rates from 1,200bps up to 230,400bps.
• Supports RTS0/CTS0 hardware flow control. The hardware hand shake line RTS0 has an
internal pull down resistor causing a low level signal, if the line is not used and open.
Although hardware flow control is recommended, this allows communication by using only
RXD and TXD lines.
• Wake up from SLEEP mode by RTS0 activation (high to low transition; see Section 3.3.3).
Note: The ASC0 modem control lines DTR0, DCD0, DSR0 and RING0 are originally available
as GPIO lines. If configured as ASC0 lines, these GPIO lines are assigned as follows:
GPIO1 --> DTR0, GPIO2 --> DCD0, GPIO3 --> DSR0 and GPIO24 --> RING0. Also, DSR0 is
shared with the SPI_CLK line of the SPI interface and may be configured as such. Configuration is done by AT command (see [1]). The configuration is non-volatile and becomes active
after a module restart.

The following figure shows the startup behavior of the asynchronous serial interface ASC0.
For pull-up and pull-down values see Table 10.
Figure 7: ASC0 startup behavior
Notes:
During startup the DTR0 signal is driven active low for 500µs. It is recommended to provide a
470
Ω serial resistor for the DTR0 line to prevent shorts.
No data must be sent over the ASC0 interface before the interface is active and ready to receive data (see Section 3.2.1).
An external pull down to ground on the DCD0 line during the startup phase activates a special
mode for ELS61-AUS. In this special mode the AT command interface is not available and the
module may therefore no longer behave as expected.

2.1.5 Serial Interface ASC1
Four ELS61-AUS GPIO lines can be configured as ASC1 interface signals to provide a 4-wire
unbalanced, asynchronous modem interface ASC1 conforming 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). For electrical
characteristics please refer to Table 2. For an illustration of the interface line’s startup behavior
see Figure 9.
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.
ELS61-AUS 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 8: 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 921,600 bps.
• Autobauding supports bit rates from 1,200bps up to 230,400bps.
• Supports RTS1/CTS1 hardware flow. The hardware hand shake line RTS0 has an internal
pull down resistor causing a low level signal, if the line is not used and open. Although hardware flow control is recommended, this allows communication by using only RXD and TXD
lines.

2.1.6 UICC/SIM/USIM Interface
ELS61-AUS 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. Please refer to Table 2 for
electrical specifications of the UICC/SIM/USIM interface lines depending on whether a 3V or
1.8V SIM card is used.
The CCIN signal serves to detect whether a tray (with SIM card) is present in the card holder.
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 ELS61-AUS and is part of the Gemalto M2M reference equipment submitted for type
approval. See Section 7.1 for Molex ordering numbers.

Signal Description
GND Separate ground connection for SIM card to improve EMC.
CCCLK Chipcard clock
CCVCC SIM supply voltage.
CCIO Serial data line, input and output.
CCRST Chipcard reset
CCIN 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 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
ELS61-AUS.
Note [1]: 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 ELS61-AUS.
Note [2]: On the evaluation board, the CCIN signal is inverted, thus the CCIN signal is by default high and
will change to a low level if a SIM card is inserted.

The total cable length between the SMT application interface pads on ELS61-AUS 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 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.
An example for an optimized ESD protection for the SIM interface is shown in Section 2.1.6.1.

2.1.7 RTC Backup
The internal Real Time Clock of ELS61-AUS is supplied from a separate voltage regulator in
the power supply component which is also active when ELS61-AUS is in Power Down mode
and BATT+ is available. An alarm function is provided that allows to wake up ELS61-AUS without logging on to the UMTS network.
In addition, you can use the VDDLP pad to backup the RTC from an external capacitor. The
capacitor is charged from the internal LDO of ELS61-AUS. If the voltage supply at BATT+ is
disconnected the RTC can be powered by the capacitor. The size of the capacitor determines
the duration of buffering when no voltage is applied to ELS61-AUS, i.e. the greater the capacitor the longer ELS61-AUS will save the date and time. The RTC can also be supplied from an
external battery (rechargeable or non-chargeable). In this case the electrical specification of
the VDDLP pad (see Section 2.1.2) has to be taken in to account.
Figure 12 shows an RTC backup configuration. A serial 1k
Ω resistor has to be placed on the
application next to VDDLP. It limits the input current of an empty capacitor or battery.

2.1.8 GPIO Interface
ELS61-AUS offers a GPIO interface with 22 GPIO lines. The GPIO lines are shared with other
interfaces or functions: Fast shutdown (see Section 2.1.13.4), status LED (see Section
2.1.13.1), the PWM functionality (see Section 2.1.11), an pulse counter (see Section 2.1.12),
ASC0 (see Section 2.1.4), ASC1 (see Section 2.1.5), an SPI interface (see Section 2.1.10).
The following table shows the configuration variants for the GPIO pads. All variants are mutually exclusive, i.e. a pad configured for instance as Status LED is locked for alternative usage.

2.1.9 I2C Interface
I2C is a serial, 8-bit oriented data transfer bus for bit rates up to 400kbps in Fast mode. It consists 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-directional line. Each device connected to the bus is software addressable by a unique 7-bit address, and simple master/slave relationships exist at all times. The module operates as mastertransmitter or as master-receiver. The customer application transmits or receives data only on
request of the module.
To configure and activate the I2C bus use the AT^SSPI command. Detailed information on the
AT^SSPI command as well explanations on the protocol and syntax required for data transmission can be found in [1].

line, the I
In the application I2CDAT and I2CCLK lines need to be connected to a positive supply voltage
via a pull-up resistor. For electrical characteristics please refer to Table 2.

2.1.10 SPI Interface
Four ELS61-AUS GPIO interface lines can be configured as Serial Peripheral Interface (SPI).
The SPI is a synchronous serial interface for control and data transfer between ELS61-AUS
and the external application. Only one application can be connected to the 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 MOSI and MISO, the clock line SPI_CLK a well as the chip select
line SPI_CS.
The four GPIO lines can be configured as SPI interface signals as follows: GPIO3 --> SPI_CLK,
GPIO16 --> MOSI, GPIO17 --> MISO and GPIO19 --> SPI_CS. The configuration is done by
AT command (see [1]). It is non-volatile and becomes active after a module restart.
The GPIO lines are also shared with the ASC1 signal lines and the ASC0 modem status signal
line DSR0.
To configure and activate the SPI interface use the AT^SSPI command. Detailed information
on the AT^SSPI command as well explanations on the SPI modes required for data transmission can be found in [1].
In general, SPI supports four operation modes. The modes are different in clock phase and
clock polarity. The module’s SPI mode can be configured by using the AT command AT^SSPI.
Make sure the module and the connected slave device works with the same SPI mode.
Figure 16 shows the characteristics of the four SPI modes. The SPI modes 0 and 3 are the most
common used modes. For electrical characteristics please refer to Table 2.

see Section 2.1.8). GPIO and PWM functionality are mutually exclusive.
The startup behavior of the lines is shown in Figure 13.
2.1.12 Pulse Counter
The GPIO8 line can be configured as pulse counter line COUNTER. The pulse counter interface can be used, for example, as a clock (for GPIOs see Section 2.1.8).
2.1.13 Control Signals
2.1.13.1 Status LED
The GPIO5 interface line can be configured to drive a status LED that indicates different operating modes of the module (for GPIOs see Section 2.1.8). GPIO and LED functionality are mu-

To take advantage of this function connect an LED to the GPIO5/LED line as shown in Figure
17.

2.1.13.2 Power Indication Circuit
In Power Down mode the maximum voltage at any digital or analog interface line must not exceed +0.3V (see also Section 2.1.2.1). Exceeding this limit for any length of time might cause
permanent damage to the module.
It is therefore recommended to implement a power indication signal that reports the module’s
power state and shows whether it is active or in Power Down mode. While the module is in
Power Down mode all signals with a high level from an external application need to be set to
low state or high impedance state. The sample power indication circuit illustrated in Figure 18
denotes the module’s active state with a low signal and the module’s Power Down mode with
a high signal or high impedance state.

2.1.13.3 Host Wakeup
If no call, data or message transfer is in progress, the host may shut down its own USB interface to save power. If a call or other request (URC’s, messages) arrives, the host can be notified of these events and be woken up again by a state transition of the ASC0 interface‘s RING0
line. This functionality should only be used with legacy USB applications not supporting the recommended USB suspend and resume mechanism as described in [5] (see also Section 2.1.3.1).
For more information on how to configure the RING0 line by AT^SCFG command see [1].
Possible RING0 line states are listed in Table 6.

2.1.13.4 Fast Shutdown
The GPIO4 interface line can be configured as fast shutdown signal line FST_SHDN. The configured FST_SHDN line is an active low control signal and must be applied for at least 10 milliseconds. If unused this line can be left open because of a configured internal pull-up resistor.
Before setting the FST_SHDN line to low, the ON signal should be set to low (see Figure 19).
Otherwise there might be back powering at the ON line in Power Down mode.
By default, the fast shutdown feature is disabled. It has to be enabled using the AT command
AT^SCFG "MEShutdown/Fso". For details see [1].
If enabled, a low impulse >10 milliseconds on the FST_SHDN line starts the fast shutdown. The
fast shutdown procedure still finishes any data activities on the module's flash file system, thus
ensuring data integrity, but will no longer deregister gracefully from the network, thus saving
the time required for network deregistration.
Please note that if enabled, the normal software controlled shutdown using AT^SMSO will also
be a fast shutdown, i.e., without network deregistration. However, in this case no URCs including shutdown URCs will be provided by the AT^SMSO command.

2.3 Sample Application
Figure 27 shows a typical example of how to integrate a ELS61-AUS module with an applica-
tion. Usage of the various host interfaces depends on the desired features of the application.
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. The
potential interferers may be minimized by placing small capacitors (47pF) at suspected lines
(e.g. RXD0, VDDLP, and 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.
Depending on the micro controller used by an external application ELS61-AUS‘s digital input
and output lines may require level conversion. Section 2.3.1 shows a possible sample level
conversion circuit.
Note: ELS61-AUS 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 27 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 individual application layout manufacturers are required to ensure adequate design and operating
safeguards for their products using ELS61-AUS modules.

3.2 Power Up/Power Down Scenarios
In general, be sure not to turn on ELS61-AUS while it is beyond the safety limits of voltage and
temperature stated in Section 2.1.2.1. ELS61-AUS immediately switches off after having started and detected these inappropriate conditions. In extreme cases this can cause permanent
damage to the module.
3.2.1 Turn on ELS61-AUS
ELS61-AUS can be turned on as described in the following sections:
• Connecting the operating voltage BATT+ (see Section 3.2.1.1).
• Hardware driven switch on by ON line: Starts Normal mode (see Section 3.2.1.2).
After startup or restart, the module will send the URC ^SYSSTART that notifies the host application that the first AT command can be sent to the module (see also [1]).
3.2.1.1 Connecting ELS61-AUS BATT+ Lines
Figure 29 and Figure 30 show sample external application circuits that allow to connect (and
also to temporarily disconnect) the module‘s BATT+ lines from the external application‘s power
supply.
Figure 29 illustrates the application of power employing an externally controlled microcontrol-
ler. Figure 30 as an alternative shows the power application with an external voltage supervi-
sory circuit instead of a microcontroller. The voltage supervisory circuit ensures that the power
is disconnected and applied again depending on given thresholds.
The transistor T2 mentioned in Figure 29 and Figure 30 should have an R
in order to minimize voltage drops.
Such circuits could be useful to maximize power savings for battery driven applications or to
completely switch off and restart the module after a firmware update.
After connecting the BATT+ lines the module can then be (re-)started as described in Section
3.2.1.2 and Section 3.2.2.

3.2.1.2 Switch on ELS61-AUS Using ON Signal
When the operating voltage BATT+ is applied, ELS61-AUS can be switched on by means of the
ON signal.
The ON signal is an edge triggered signal and only allows the input voltage level of the VDDLP
signal. The module starts into normal mode on detecting the rising edge of the ON signal.
The following Figure 31 shows recommendations for possible switch-on circuits.
Figure 31: ON circuit options
It is recommended to set a serial 1kOhm resistor between the ON circuit and the external capacitor or battery at the VDDLP power supply (i.e., RTC backup circuit). This serial resistor protection is necessary in case the capacitor or battery has low power (is empty).
With Option 2 the typical resistor values are: R1 = 150k and R2 = 22k. But the resistor values
depend on the current gain from the employed PNP resistor.

Please note that the ON signal is an edge triggered signal. This implies that a milli-second high
pulse on the signal line suffices to almost immediately switch on the module, as shown in Fig-
ure 32. After module startup the ON signal should always be set to low to prevent possible back
powering at this pad.

3.2.2 Restart ELS61-AUS
After startup ELS61-AUS can be re-started as described in the following sections:
• Software controlled reset by AT+CFUN command: Starts Normal mode (see Section
3.2.2.1).
• Hardware controlled reset by EMERG_RST line: Starts Normal mode (see Section 3.2.2.2).
3.2.2.1 Restart ELS61-AUS via AT+CFUN Command
To reset and restart the ELS61-AUS module use the command AT+CFUN. See [1] for details.

3.2.2.2 Restart ELS61-AUS Using EMERG_RST
The EMERG_RST signal is internally connected to the central baseband processor. A low level
for more than 10ms sets the processor and with it all the other signal pads to their respective
reset state. The reset state is described in Section 3.2.3 as well as in the figures showing the
startup behavior of an interface.
After releasing the EMERG-RST line, i.e., with a change of the signal level from low to high,
the module restarts. The other signals continue from their reset state as if the module was
switched on by the ON signal.
Figure 33: Emergency restart timing
It is recommended to control this EMERG_RST line with an open collector transistor or an open
drain field-effect transistor.
Caution: Use the EMERG_RST line only when, due to serious problems, the software is not
responding for more than 5 seconds. Pulling the EMERG_RST line causes the loss of all information stored in the volatile memory. Therefore, this procedure is intended only for use in case
of emergency, e.g. if ELS61-AUS does not respond, if reset or shutdown via AT command fails.

3.2.3 Signal States after Startup
Table 10 lists the states each interface signal passes through during reset phase and the first
firmware initialization. For further firmware startup initializations the values may differ because
of different GPIO line configurations.
The reset state is reached with the rising edge of the EMERG_RST signal - either after a normal
module startup (see Section 3.2.1.2) or after a reset (see Section 3.2.2.2). After the reset state
has been reached the firmware initialization state begins. The firmware initialization is completed as soon as the ASC0 interface lines CTS0, DSR0 and RING0 as well as the ASC1 interface
line CTS1 have turned low (see Section 2.1.4 and Section 2.1.5). Now, the module is ready to
receive and transmit data.

3.2.4 Turn off ELS61-AUS
To switch the module off the following procedures may be used:
• Software controlled shutdown procedure: Software controlled by sending an AT command
over the serial application interface. See Section 3.2.4.1.
• Hardware controlled shutdown procedure: Hardware controlled by disconnecting the mod-
ule‘s power supply lines BATT+ (see Section 3.2.1.1).
• Automatic shutdown (software controlled): See Section 3.2.5
- Takes effect if ELS61-AUS board temperature or voltage levels exceed a critical limit.
3.2.4.1 Switch off ELS61-AUS Using AT Command
The best and safest approach to powering down ELS61-AUS is to issue the appropriate AT
command. This procedure lets ELS61-AUS log off from the network and allows the software to
enter into a secure state and safe data before disconnecting the power supply. The mode is
referred to as Power Down mode. In this mode, only the RTC stays active.After sending
AT^SMSO command DO NOT enter any other AT commands. To verify that the module is
turned off it is allowed to monitor the PWR_IND signal (see Section 2.1.13.2). Note that a high
state of the PWR_IND signal line indicates that the module is switched off.
Be sure not to disconnect the operating voltage V
before V180 pad has gone low. Other-
BATT+
wise you run the risk of losing data. The system power down procedure may take up to a few
seconds.
While ELS61-AUS is in Power Down mode the application interface is switched off and must
not be fed from any other voltage source. Therefore, your application must be designed to
avoid any current flow into any digital pads of the application interface.

3.2.5 Automatic Shutdown
Automatic shutdown takes effect if the following event occurs:
• ELS61-AUS board is exceeding the critical limits of overtemperature or undertemperature
(see Section 3.2.5.1)
• Undervoltage or overvoltage is detected (see Section 3.2.5.2 and Section 3.2.5.3)
The automatic shutdown procedure is equivalent to the power-down initiated with an AT command, i.e. ELS61-AUS logs off from the network and the software enters a secure state avoiding loss of data.
3.2.5.1 Thermal Shutdown
The board temperature is constantly monitored by an internal NTC resistor located on the PCB.
The values detected by the NTC resistor are measured directly on the board and therefore, are
not fully identical with the ambient temperature.
Each time the board temperature goes out of range or back to normal, ELS61-AUS instantly
displays an alert (if enabled).
• URCs indicating the level "1" or "-1" allow the user to take appropriate precautions, such as
protecting the module from exposure to extreme conditions. The presentation of the URCs
depends on the settings selected with the AT^SCTM write command (for details see [1]):
AT^SCTM=1: Presentation of URCs is always enabled.
AT^SCTM=0 (default): Presentation of URCs is enabled during the 2 minute guard period
after start-up of ELS61-AUS. After expiry of the 2 minute guard period, the presentation of
URCs will be disabled, i.e. no URCs with alert levels "1" or ''-1" will be generated.
• URCs indicating the level "2" or "-2" are instantly followed by an orderly shutdown. The presentation of these URCs is always enabled, i.e. they will be output even though the factory
setting AT^SCTM=0 was never changed.
The maximum temperature ratings are stated in Section 3.5. Refer to Table 11 for the associated URCs.

Sending temperature alert (2min after ELS61-AUS start-up, otherwise only if URC presentation
enabled)

3.2.5.2 Undervoltage Shutdown
Page 62 of 102
The undervoltage shutdown threshold is the specified minimum supply voltage V
BATT+
given in
Table 2. When the average supply voltage measured by ELS61-AUS approaches the under-
voltage shutdown threshold (i.e., 0.05V offset) the module will send the following URC:
^SBC: Undervoltage Warning
The undervoltage warning is sent only once - until the next time the module is close to the undervoltage shutdown threshold.
If the voltage continues to drop below the specified undervoltage shutdown threshold, the module will send the following URC:
^SBC: Undervoltage Shutdown
This alert is sent only once before the module shuts down cleanly without sending any further
messages.
This type of URC does not need to be activated by the user. It will be output automatically when
fault conditions occur.
Note: For battery powered applications it is strongly recommended to implement a BATT+ connecting circuit as described in Section 3.2.1.1 in order to not only be able save power, but also
to restart the module after an undervoltage shutdown where the battery is deeply discharged.
Also note that the undervoltage threshold is calculated for max. 400mV voltage drops during
transmit burst. Power supply sources for external applications should be designed to tolerate
400mV voltage drops without crossing the lower limit of 3.0 V. For external applications operating at the limit of the allowed tolerance the default undervoltage threshold may be adapted
by subtracting an offset. For details see [1]: AT^SCFG= "MEShutdown/sVsup/threshold".
3.2.5.3 Overvoltage Shutdown
The overvoltage shutdown threshold is the specified maximum supply voltage V
Table 2. When the average supply voltage measured by ELS61-AUS approaches the overvolt-
age shutdown threshold (i.e., 0.05V offset) the module will send the following URC:
^SBC: Overvoltage Warning
The overvoltage warning is sent only once - until the next time the module is close to the overvoltage shutdown threshold.
If the voltage continues to rise above the specified overvoltage shutdown threshold, the module
will send the following URC:
^SBC: Overvoltage Shutdown
This alert is sent only once before the module shuts down cleanly without sending any further
messages.
This type of URC does not need to be activated by the user. It will be output automatically when
fault conditions occur.
Keep in mind that several ELS61-AUS components are directly linked to BATT+ and, therefore,
the supply voltage remains applied at major parts of ELS61-AUS. Especially the power amplifier linked to BATT+
is very sensitive to high voltage and might even be destroyed.

3.3 Power Saving

3.3 Power Saving
ELS61-AUS can be configured to control power consumption:
• Using the AT command AT^SPOW it is possible to specify a so-called power saving mode
for the module (<mode> = 2; for details on the command see [1]). The module‘s UART interfaces (ASC0 and ASC1) are then deactivated and will only periodically be activated to be
able to listen to network paging messages as described in Section 3.3.1 and Section 3.3.2.
See Section 3.3.3 for a description on how to immediately wake up ELS61-AUS again using
RTS0.
Please note that the AT^SPOW setting has no effect on the USB interface. As long as the
USB connection is active, the module will not change into its SLEEP state to reduce its functionality to a minimum and thus minimizing its current consumption. To enable switching
into SLEEP mode, the USB connection must therefore either not be present at all or the
USB host must bring its USB interface into Suspend state. Also, VUSB_IN should always
be kept enabled for this functionality. See “Universal Serial Bus Specification Revision 2.0”
for a description of the Suspend state.

3.3.1 Power Saving while Attached to WCDMA Networks
The power saving possibilities while attached to a WCDMA network depend on the paging timing cycle of the base station.
During normal WCDMA operation, i.e., the module is connected to a WCDMA network, the
duration of a power saving period varies. It may be calculated using the following formula:
DRX value
t = 2
DRX (Discontinuous Reception) in WCDMA networks is a value between 6 and 9, thus resulting in power saving intervals between 0.64 and 5.12 seconds. The DRX value of the base station is assigned by the WCDMA network operator.
In the pauses between listening to paging messages, the module resumes power saving, as
shown in Figure 35.
* 10 ms (WCDMA frame duration).
Figure 35: Power saving and paging in WCDMA networks
The varying pauses explain the different potential for power saving. The longer the pause the
less power is consumed.

Generally, power saving depends on the module’s application scenario and may differ from the
above mentioned normal operation. The power saving interval may be shorter than 0.64 seconds or longer than 5.12 seconds.
3.3.2 Power Saving while Attached to LTE Networks
The power saving possibilities while attached to an LTE network depend on the paging timing
cycle of the base station.
During normal LTE operation, i.e., the module is connected to an LTE network, the duration of
a power saving period varies. It may be calculated using the following formula:
t = DRX Cycle Value * 10 ms
DRX cycle value in LTE networks is any of the four values: 32, 64, 128 and 256, thus resulting
in power saving intervals between 0.32 and 2.56 seconds. The DRX cycle value of the base
station is assigned by the LTE network operator.
In the pauses between listening to paging messages, the module resumes power saving, as
shown in Figure 36.
Figure 36: Power saving and paging in LTE networks
The varying pauses explain the different potential for power saving. The longer the pause the
less power is consumed.
Generally, power saving depends on the module’s application scenario and may differ from the

3.3.3 Wake-up via RTS0
RTS0 can be used to wake up ELS61-AUS from SLEEP mode configured with AT^SPOW.
Assertion of RTS0 (i.e., toggle from inactive high to active low) serves as wake up event, thus
allowing an external application to almost immediately terminate power saving. After RTS0
assertion, the CTS0 line signals module wake up, i.e., readiness of the AT command interface.
It is therefore recommended to enable RTS/CTS flow control (default setting).
Figure 37 shows the described RTS0 wake up mechanism.

The power supply of ELS61-AUS has to be a single voltage source at BATT+
and BATT+RF.
BB
It must be able to provide the peak current during the uplink transmission.
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.

3.4.3 Monitoring Power Supply by AT Command
To monitor the supply voltage you can also use the AT^SBV command which returns the value
related to the reference points BATT+ and GND.
The module continuously measures the voltage at intervals depending on the operating mode
of the RF interface. The duration of measuring ranges from 0.5 seconds in TALK/DATA mode
to 50 seconds when ELS61-AUS is in IDLE mode or Limited Service (deregistered). The displayed voltage (in mV) is averaged over the last measuring period before the AT^SBV command was executed.
If the measured voltage drops below or rises above the voltage shutdown thresholds, the module will send an "^SBC" URC and shut down (for details see Section 3.2.5).

3.6 Electrostatic Discharge
The module is not protected against Electrostatic Discharge (ESD) in general. 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 ELS61-AUS module.
An example for an enhanced ESD protection for the SIM interface is given in Section 2.1.6.1.
ELS61-AUS has been tested according to group standard
ETSI EN 301 489-1 (see Table 22) and
test standard EN 61000-4-2. Electrostatic values can be gathered from the following table.

Note: 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 Gemalto reference application described in Chapter 5.
3.6.1 ESD Protection for Antenna Interfaces
The following Figure 39 shows how to implement an external ESD protection for the RF anten-
na interfaces (ANT_MAIN and ANT_DRX) with either a T pad or PI pad attenuator circuit (for
RF line routing design see also Section 2.2.3).
Recommended inductor types for the above sample circuits: Size 0402 SMD from Panasonic
ELJRF series (22nH and 18nH inductors) or Murata LQW15AN18NJ00 (18nH inductors only).

3.7 Blocking against RF on Interface Lines
73
3.7 Blocking against RF on In terface Lines
To reduce EMI issues there are serial resistors, or capacitors to GND, implemented on the
module for the ignition, emergency restart, and SIM interface lines (cp. Section 2.3). However,
all other signal lines have no EMI measures on the module and there are no blocking measures
at the module’s interface to an external application.
Dependent on the specific application design, it might be useful to implement further EMI measures on some signal lines at the interface between module and application. These measures
are described below.
There are five possible variants of EMI measures (A-E) that may be implemented between
module and external application depending on the signal line (see Figure 40 and Table 16). Pay
attention not to exceed the maximum input voltages and prevent voltage overshots if using inductive EMC measures.
The maximum value of the serial resistor should be lower than 1k
Ω on the signal line. The max-
imum value of the capacitor should be lower than 50pF on the signal line. Please observe the
electrical specification of the module‘s SMT application interface and the external application‘s
interface.
Figure 40: EMI circuits
Note: In case the application uses an internal RF antenna that is implemented close to the
ELS61-AUS module, Gemalto strongly recommends sufficient EMI measures, e.g. of type B or
C, for each digital input or output.

4.2 Mounting ELS61-AUS onto the Application Platform
This section describes how to mount ELS61-AUS onto the PCBs, including land pattern and
stencil design, board-level characterization, soldering conditions, durability and mechanical
handling. For more information on issues related to SMT module integration see also [3].
Note: To avoid short circuits between signal tracks on an external application's PCB and various markings at the bottom side of the module, it is recommended not to route the signal tracks
on the top layer of an external PCB directly under the module, or at least to ensure that signal
track routes are sufficiently covered with solder resist.
4.2.1 SMT PCB Assembly
4.2.1.1 Land Pattern and Stencil
The land pattern and stencil design as shown below is based on Gemalto characterizations for
lead-free solder paste on a four-layer test PCB and a respectively 110 micron and 150 micron
thick stencil.
The land pattern given in Figure 43 reflects the module‘s pad layout, including signal pads and
ground pads (for pad assignment see Section 2.1.1).
Figure 43: Land pattern (top view)
The stencil design illustrated in Figure 44 and Figure 45 is recommended by Gemalto M2M as
a result of extensive tests with Gemalto M2M Daisy Chain modules.
The central ground pads are primarily intended for stabilizing purposes, and may show some
more voids than the application interface pads at the module's rim. This is acceptable, since
they are electrically irrelevant.

4.2.1.2 Board Level Characterization
Board level characterization issues should also be taken into account if devising an SMT process.
Characterization tests should attempt to optimize the SMT process with regard to board level
reliability. This can be done by performing the following physical tests on sample boards: Peel
test, bend test, tensile pull test, drop shock test and temperature cycling. Sample surface
mount checks are described in [3].
It is recommended to characterize land patterns before an actual PCB production, taking individual processes, materials, equipment, stencil design, and reflow profile into account. For land
and stencil pattern design recommendations see also Section 4.2.1.1. Optimizing the solder
stencil pattern design and print process is necessary to ensure print uniformity, to decrease solder voids, and to increase board level reliability.
Daisy chain modules for SMT characterization are available on request. For details refer to [3].
Generally, solder paste manufacturer recommendations for screen printing process parameters and reflow profile conditions should be followed. Maximum ratings are described in Section
4.2.3.
4.2.2 Moisture Sensitivity Level
ELS61-AUS comprises components that are susceptible to damage induced by absorbed
moisture.
Gemalto M2M’s ELS61-AUS module complies with the latest revision of the IPC/JEDEC JSTD-020 Standard for moisture sensitive surface mount devices and is classified as MSL 4.
For additional moisture sensitivity level (MSL) related information see Section 4.2.4 and Sec-
tion 4.3.2.

4.2.3.2 Maximum Temperature and Duration
The following limits are recommended for the SMT board-level soldering process to attach the
module:
• A maximum module temperature of 240°C. This specifies the temperature as measured at
the module’s top side.
• A maximum duration of 15 seconds at this temperature.
Please note that while the solder paste manufacturers' recommendations for best temperature
and duration for solder reflow should generally be followed, the limits listed above must not be
exceeded.
ELS61-AUS is specified for one soldering cycle only. Once ELS61-AUS is removed from the
application, the module will very likely be destroyed and cannot be soldered onto another application.

4.2.4.2 Processing Life
ELS61-AUS must be soldered to an application within 72 hours after opening the moisture barrier bag (MBB) it was stored in.
As specified in the IPC/JEDEC J-STD-033 Standard, the manufacturing site processing the
modules should have ambient temperatures below 30°C and a relative humidity below 60%.
4.2.4.3 Baking
Baking conditions are specified on the moisture sensitivity label attached to each MBB (see
Figure 51 for details):
• It is not necessary to bake ELS61-AUS, if the conditions specified in Section 4.2.4.1 and
Section 4.2.4.2 were not exceeded.
• It is necessary to bake ELS61-AUS, if any condition specified in Section 4.2.4.1 and Section
4.2.4.2 was exceeded.
If baking is necessary, the modules must be put into trays that can be baked to at least 125°C.
Devices should not be baked in tape and reel carriers at any temperature.
4.2.4.4 Electrostatic Discharge
Electrostatic discharge (ESD) may lead to irreversable damage for the module. It is therefore
advisable to develop measures and methods to counter ESD and to use these to control the
electrostatic environment at manufacturing sites.
Please refer to Section 3.6 for further information on electrostatic discharge.

MBBs contain one or more desiccant pouches to absorb moisture that may be in the bag. The
humidity indicator card described below should be used to determine whether the enclosed
components have absorbed an excessive amount of moisture.
The desiccant pouches should not be baked or reused once removed from the MBB.
The humidity indicator card is a moisture indicator and is included in the MBB to show the approximate relative humidity level within the bag. Sample humidity cards are shown in Figure 52.
If the components have been exposed to moisture above the recommended limits, the units will
have to be rebaked.

6.4 Safety Precaution Notes
99
Page 99 of 102
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 ELS61-AUS. 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.
