Table 2: SARA-G3 series GSM/GPRS characteristics summary
The network automatically configures the channel encoding used by the module, depending on
conditions and the quality of the radio link between cell phone and base station. If the channel is very
noisy, the network may use the most robust coding scheme (CS-1) to ensure higher reliability. If the
channel provides good conditions, the network can use the least robust but fastest coding scheme
(CS-4) to obtain optimum speed.
2
Device can be attached to both GPRS and GSM services (i.e. Packet Switch and Circuit Switch mode) using one service at a time.
3
GPRS multi-slot class 10 implies a maximum of 4 slots in DL (reception) and 2 slots in UL (transmission) with 5 slots in total.
4
The maximum bit rate of the module depends on the current network settings.

The quality of the GPRS UL and/or DL connection is returned by the AT+CSQ
command.
Network Friendly
Mode 9
SARA-G340 /
SARA-G350
When the Network Friendly Mode is enabled, the module reacts to service
request denials by using time-spaced, randomized or delayed retry schemes
according to GSMA IoT Device Connection Efficiency Guidelines [13].
The feature can be enabled through the +UNFM, +UNFMCONF, +URPM AT
commands.
Smart Temperature
Supervisor
SARA-G340 /
SARA-G350
Constant monitoring of the module board temperature:
Warning notification when the temperature approaches an upper or lower
predefined threshold
Shutdown notified and forced when the temperature value is outside the
specified range (shutdown suspended in case of an emergency call in
progress)
The Smart Temperature Supervisor feature can be enabled or disabled through
an AT command (see the u-blox AT commands manual [1], +USTS AT
command)
☞ The sensor measures board temperature inside the shields, which can
differ from ambient temperature.
Power saving
All
The power saving configuration is by default disabled, but it can be configured
using an AT command. When power saving is enabled, the module
automatically enters the low power idle-mode whenever possible, reducing
current consumption.
During idle-mode, the module processor core runs with the RTC 32 kHz
reference clock, which is generated by:
The internal 32 kHz oscillator, in case of SARA-G340 and SARA-G350
modules
The 32 kHz signal provided at the EXT32K input pin, in case of SARA-G300
and SARA-G310 modules
For more details, see the SARA-G3 / SARA-U2 Series System Integration
Manual [2] and the u-blox AT commands manual [1], +UPSV AT command.

2 Interfaces
2.1 Power management
2.1.1 Module supply input (VCC)
SARA-G3 modules must be supplied through the three VCC pins by a DC power supply. Voltages
must be stable: during operation, the current drawn from VCC can vary by some order of magnitude,
especially due to the surging consumption profile of the GSM system (described in the SARA-G3 /
SARA-U2 Series System Integration Manual [2]). It is important that the system power supply
circuit is able to support peak power.
SARA-G3 modules product versions “02” onwards provide separate supply inputs over the three
VCC pins:
VCC pins #52 and #53 represent the supply input for the internal RF power amplifier, demanding
most of the total current drawn of the module when RF transmission is enabled during a
voice/data call
VCC pin #51 represents the supply input for the internal baseband Power Management Unit and
the internal transceiver, demanding minor part of the total current drawn of the module when RF
transmission is enabled during a voice/data call
2.1.2 RTC supply input/output (V_BCKP)
V_BCKP is the Real Time Clock (RTC) supply of SARA-G3 modules. When VCC voltage is within the
valid operating range, the internal Power Management Unit (PMU) supplies the RTC and the same
supply voltage is available on V_BCKP pin. If the VCC voltage is under the minimum operating limit
(e.g. during not powered mode), the V_BCKP pin can externally supply the RTC.
2.1.3 Digital I/O interfaces supply output (V_INT)
SARA-G3 modules provide an internally generated supply rail output for digital interfaces (V_INT).
This can be used in place of an external discrete regulator to supply pull-up resistors on the DDC
interface. This optimizes the bill of material for various applications, e.g. with u-blox positioning
modules operating at 1.8 V.
2.2 Antenna
2.2.1 Antenna RF interface (ANT)
The ANT pin has an impedance of 50 and provides the RF antenna interface of SARA-G3 modules.
2.2.2 Antenna detection (ANT_DET)
The ANT_DET pin is an Analog to Digital Converter (ADC) input provided only by SARA-G340 and
SARA-G350 modules to sense the antenna presence (as optional feature), evaluating the resistance
from the ANT pin to GND by means of an external antenna detection circuit implemented on the
application board. For more details, see the SARA-G3 / SARA-U2 Series System Integration Manual
[2] and the u-blox AT Commands Manual [1], +UANTR.

UBX-13000993 - R21 Interfaces Page 13 of 49
2.3 System functions
2.3.1 Module power-on (PWR_ON)
SARA-G3 modules can be switched on in one of the following ways:
Rising edge on the VCC pin to a valid voltage for module supply, i.e. applying module supply
Low level on the PWR_ON input pin, i.e. forcing the pin (normally high with external pull-up) to
a low level for a valid time period (see section 4.2.7). The PWR_ON pin requires an external
pull-up resistor to set its value to logic high and may not be left floating
RTC alarm, i.e. pre-programmed scheduled time (see the u-blox AT Commands Manual [1],
AT+CALA)
☞ SARA-G300 and SARA-G310 cannot be switched on with RTC alarm.
2.3.2 Module power-off
SARA-G3 modules can be properly switched off, with storage of current settings and network
detach, by:
AT+CPWROFF command
An abrupt under-voltage shutdown occurs on SARA-G3 modules when the VCC supply drops below
the extended operating range minimum limit, but in this case it is not possible to perform the
storing of the current parameter settings in the module’s non-volatile memory as well as the proper
network detach.
An over-temperature or an under-temperature shutdown occurs on SARA-G3 modules when the
temperature measured within the cellular module reaches the dangerous area, if the optional Smart
Temperature Supervisor feature is enabled and configured by the dedicated AT command. For more
details, see the SARA-G3 / SARA-U2 Series System Integration Manual [2] and the u-blox AT
commands manual [1], +USTS AT command.
2.3.3 Module reset (RESET_N)
SARA-G3 modules can be properly reset (rebooted), with storage of current parameter settings in
the module’s non-volatile memory and proper network detach, in this way:
AT+CFUN command (see the u-blox AT Commands Manual [1]). This causes an “internal” or
“software” reset of the module.
An abrupt “external” or “hardware” reset occurs when a low level is applied to the RESET_N pin,
which is normally set high by an internal pull-up, for a valid time period (see section 4.2.8), but in this
case it is not possible to perform the storing of the current parameter settings as well as the proper
network detach.
2.3.4 External 32 kHz signal input (EXT32K)
SARA-G300 and SARA-G310 provide the EXT32K input pin that must be fed by a proper 32 kHz
signal to furnish the reference clock for the RTC, allowing very low power idle-mode and RTC
functions support. See section 4.2.9 for detailed electrical specifications for the 32 kHz signal.
SARA-G340 and SARA-G350 do not provide the EXT32K input pin. An internal 32 kHz oscillator
automatically generates the reference clock for the RTC, allowing very low power idle-mode and RTC
functions support.
SARA-G3 series - Data Sheet
UBX-13000993 - R21 Interfaces Page 14 of 49
2.3.5 Internal 32 kHz signal output (32K_OUT)
SARA-G300 and SARA-G310 provide the 32K_OUT output pin which gives a 32 kHz reference signal
suitable only to feed the EXT32K input pin of SARA-G300 / SARA-G310 modules, furnishing the
reference clock for the RTC, allowing low power idle-mode and RTC functions support with modules
switched on.
SARA-G340 and SARA-G350 do not provide the 32K_OUT output; there is no EXT32K input on these
modules.
2.4 SIM
2.4.1 (U)SIM interface
A (U)SIM card interface is available via the VSIM, SIM_IO, SIM_CLK, SIM_RST pins of SARA-G3
series modules: the high-speed SIM/ME interface is implemented as well as the automatic detection
of the required SIM supporting voltage.
Both 1.8 V and 3 V SIM types are supported: activation and deactivation with automatic voltage
switch from 1.8 V to 3 V are implemented, according to ISO-IEC 7816-3 Specifications. The SIM driver
supports the PPS procedure for baud-rate selection, according to the values proposed by the SIM
Card.
2.4.2 SIM card detection (SIM_DET)
☞ Not supported by SARA-G300-00S and SARA-G310-00S modules.
The SIM_DET pin of SARA-G3 modules is a digital input provided to sense the SIM card presence (as
an optional feature), when it is properly connected to the mechanical switch of the SIM card holder
(for more details, see the SARA-G3 / SARA-U2 Series System Integration Manual [2]).

SARA-G340 ATEX and SARA-G350 ATEX modules, in addition to the approvals for main certification
schemes (see section 6.2.1), are certified as components intended for use in potentially explosive
atmospheres compliant to the following standards:
IEC 60079-0: 2011
IEC 60079-11: 2011
IEC 60079-26: 2006
The certification number of SARA-G340 ATEX and SARA-G350 ATEX modules according to the
ATEX directive 2014/34/EU is:
SIQ 13 ATEX 032 U
The certification number of SARA-G340 ATEX and SARA-G350 ATEX modules according to the
IECEx conformity assessment system is:
IECEx SIQ 13.0004U
According to the standards listed above, the SARA-G340 ATEX and SARA-G350 ATEX modules are
certified with the following marking:
Ex II 1G, Ex ia IIC/IIB
According to the marking stated above, the SARA-G340 ATEX and SARA-G350 ATEX modules are
certified as electrical equipment of:
group ‘II’: intended for use in areas with explosive gas atmosphere other than mines
susceptible to firedamp
category ‘1G’: intended for use in zone 0 hazardous areas, in which explosive atmospheres
caused by mixtures of air and gases, vapors or mists are present continuously, for long
periods or frequently
level of protection ‘ia’: intrinsically safe apparatus with very high level of protection, not
capable of causing ignition in normal operation and with the application of one countable
fault or a combination of any two countable fault plus those non-countable faults which give
the most onerous condition
subdivision ‘IIC/IIB’: intended for use in areas where the nature of the explosive gas
atmosphere is considered very dangerous based on the Maximum Experimental Safe Gap or
the Minimum Ignition Current ratio of the explosive gas atmosphere in which the equipment
may be installed (a typical gas is hydrogen), so that the modules are also suitable for
applications intended for use in subdivision IIB (typical gas is ethylene) and subdivision IIA (a
typical gas is propane)
Section 4.2.1 defines the temperature range of use of SARA-G340 ATEX and SARA-G350 ATEX
modules.
The RF radiating profile of SARA-G340 ATEX and SARA-G350 ATEX modules is compliant to all the
applicable 3GPP / ETSI standards, with a maximum of 2 W RF pulse power and 1.15 mJ RF pulse
energy according to the GSM/GPRS power class stated in Table 2.

7.2 Moisture sensitivity levels
⚠ SARA-G3 series modules are Moisture Sensitive Devices (MSD) in accordance to the IPC/JEDEC
specification.
The Moisture Sensitivity Level (MSL) relates to the packaging and handling precautions required.
SARA-G3 series modules are rated at MSL level 4. For more information regarding moisture
sensitivity levels, labeling, storage and drying, see the u-blox Package Information Guide [5].
☞ For MSL standard see IPC/JEDEC J-STD-020 (can be downloaded from www.jedec.org).

7.3 Reflow soldering
Reflow profiles are to be selected according to u-blox recommendations (see SARA-G3 / SARA-U2
Series System Integration Manual [2]).
⚠ Failure to observe these precautions can result in severe damage to the device!
7.4 ESD precautions
⚠ SARA-G3 series modules contain highly sensitive electronic circuitry and are Electrostatic
Sensitive Devices (ESD). Handling SARA-G3 series modules without proper ESD protection may
destroy or damage them permanently.
SARA-G3 series modules are Electrostatic Sensitive Devices (ESD) and require special ESD
precautions typically applied to ESD sensitive components.
Table 8 reports the maximum ESD ratings of the SARA-G3 modules.
Proper ESD handling and packaging procedures must be applied throughout the processing,
handling and operation of any application that incorporates SARA-G3 series modules.
ESD precautions should be implemented on the application board where the module is mounted, as
described in the SARA-G3 / SARA-U2 Series System Integration Manual [2].
⚠ Failure to observe these precautions can result in severe damage to the device!
