SARA-U2 series - Data Sheet
1 Functional description
1.1 Overview
The SARA-U2 series modules are a 3.75G UMTS/HSPA solution with GSM/(E)GPRS fall-back in the miniature
(26.0 x 16.0 mm, 96-pin) SARA LGA form factor that allows seamless drop-in migration from / to other u-blox
cellular modules families.
SARA-U2 modules feature HSPA data-rates of 7.2 Mb/s (downlink) and 5.76 Mb/s (uplink). The modules offer
data and voice communication over an extended operating temperature range of –40 °C to +85 °C, with low
power consumption and a rich feature set including dual-stack IPv4 / IPv6.
The SARA-U2 series includes variants supporting band combinations for worldwide operation, for North America
operation and for operation in Europe, Asia and other countries. Cost-saving UMTS-only variant is also available.
SARA-U2 modules are complete, fully qualified and certified solutions, which reduce costs and enable short time
to market. They are ideally suited to M2M applications such as: mobile Internet terminals, car infotainment and
telematics, Automatic Meter Reading (AMR), Remote Monitoring Automation and Control (RMAC), surveillance
and security, road pricing, asset tracking, fleet management, anti-theft systems, and Point of Sales (PoS)
terminals. SARA-U2 modules support full access to u-blox GNSS receivers via serial port. Thus any host processor
connected to the cellular module through a single serial port can control both the cellular module and the
positioning chip/module. The compact SARA 26.0 x 16.0 mm form factor with LGA pads (functionally, referred
to as “pins”) allows fully automated assembly with standard pick & place and reflow soldering equipment for
cost-efficient, high-volume production.

File Transfer Protocol as well as Secure File Transfer Protocol (SSL encryption of FTP control channel)
functionalities are supported via AT commands.
HTTP, HTTPS
Hyper-Text Transfer Protocol as well as Secure Hyper-Text Transfer Protocol (SSL encryption) functionalities is
supported via AT commands. HEAD, GET, POST, DELETE and PUT operations are available. Up to four client
contexts can be simultaneously used.
Embedded TLS 1.214
With the support of X.509 certificates, Embedded TLS 1.2 provides server and client authentication, data
encryption, data signature and enables TCP/IP applications like HTTPS and FTPS to communicate over a secured
and trusted connection.
The feature can be configured and enabled by +USECMNG and +USECPRF AT commands.
IPv4/IPv6 dual-stack
GNSS via modem
Capability to move between IPv4 and dual stack network infrastructures using external context. IPv4 and IPv6
addresses can be used.
Full access to u-blox positioning chips and modules is available through a dedicated DDC (I2C) interface. This
means that from any host processor a single serial port can control the cellular module and the positioning chip
or module. For more details see the GNSS Implementation Application Note [7].
Embedded AssistNow
Software
Embedded AssistNow Online and AssistNow Offline clients to provide better GNSS performance and faster
Time-to-First-Fix. An AT command can enable / disable the clients.
CellLocate®
Enables the estimation of device position based on the parameters of the mobile network cells visible to the
specific device based on the CellLocate® database:
Normal scan: only the parameters of the visible home network cells are sent
Deep scan: the parameters of all surrounding cells of all mobile operators are sent
CellLocate® is implemented using a set of AT commands that allow configuration and position request.
Hybrid Positioning
The module current position is provided using a u-blox positioning chip or module or the estimated position from
CellLocate® depending by which positioning method provides the best and fastest solution according to the user
configuration.
Hybrid positioning is implemented through a set of AT commands that allow configuration and position request.
Control Plan Aiding /
LCS14
Assisted GPS Location Services feature, which is based on the Radio Resources Location Protocol (RRLP),
according to 3GPP TS 44.031 [9], and Radio Resource Control (RRC), according to 3GPP TS 25.331 [17]. With the
Assisted GPS feature, a location server provides the module with the GPS system information that otherwise
must be downloaded from satellites. The feature allows faster position fixes, increases sensitivity and reduces
module power consumption. The feature is invoked by the module through LCS Supplementary Services or by
the Network during emergency calls.
Firmware update Over
AT commands (FOAT)
Firmware module upgrade over UART and USB interface using AT command.
The firmware upgrade can be executed through the +UFWUPD AT command.
Smart Temperature
Supervisor
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 feature can be enabled or disabled through the +USTS AT command.
The sensor measures board temperature, which can differ from ambient temperature.
SIM Access Profile (SAP)
Allows access and use of a remote (U)SIM card instead of the local SIM card directly connected to the module
(U)SIM interface. The module acts as an SAP Client establishing a connection and performing data exchange to a

Feature
Description
In-Band Modem13
In-Band modem solution for eCall and ERA-GLONASS emergency call applications over cellular networks
implemented according to the 3GPP TS 26.267 specification [8].
When activated, the in-vehicle eCall / ERA-GLONASS system (IVS) creates an emergency call carrying both voice
and data (including vehicle position data) directly to the nearest Public Safety Answering Point (PSAP) to
determine whether rescue services should be dispatched to the known position.
DTMF decoder
Power saving
During a voice call, the Dual-Tone Multi-Frequency detector analyses the RX speech (coming from the remote
party). The detected DTMF symbols can be output via the related URC.
For more details, see the +UDTMFD AT command.
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.
The feature can be enabled through the +UPSV AT command.
Automatic selection of
authentication type14
Automatic selection of authentication type during PDP context activation. The module will sequentially try
different authentication protocols (none/CHAP/PAP) until the authentication succeeds.
The feature can be enabled through the +UPSD and +UAUTHREQ AT commands.
Signal quality report for
Packet Switched calls14
The quality of the GPRS UL and/or DL connection is returned by the AT+CSQ command.
eMLPP14
Multi-Level Precedence and Pre-emption Service (eMLPP) permits to handle the call priority. The maximum
priority associated to a user is set in the SIM: within this threshold, the user can assign different priorities to the
calls. This results in a differentiated treatment of the calls by the network in case of abnormal events such as
handovers to congested cells.
The feature can be enabled through the +CAEMLPP, +CPPS, +CAAP AT commands.
Network Friendly Mode14
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 [18].
The feature can be enabled through the +UNFM, +UNFMCONF and +URPM AT commands.
Ethernet (CDC-ECM)
over USB interface14
Ethernet (CDC-ECM) interface allowing networking from a HOST by means of the IP address received from the
cellular network (bridge mode).
The HOST configuration is performed via the DHCP protocol (a DHCP server is implemented).
It operates as a not exclusive alternative to PPP dial-up.
The feature can be configured by +UUSBCONF and enabled by +UCEDATA AT commands.
ODIS15
OMA-DM IMEI Sync (ODIS) is an AT&T functionality required at the cellular module level and used to identify the
end device operating inside the network.
Last gasp16
In case of power supply outage (i.e. main supply interruption, battery removal, battery voltage below a certain
threshold) the cellular module can be configured to send an alarm notification to a remote entity.
The feature can be enabled and configured through the +ULGASP AT command.
Firmware update Over
The Air (FOTA)16
Embedded FOTA client to enable the Firmware module update over the cellular air interface.
The feature can be enabled and configured through the +UFWINSTALL AT command.
Smart radio Coverage
Manager (SCM)16
Smart radio coverage manager is a feature that aims to reduce the power consumption in those cellular
scenarios where the radio coverage or the network conditions would cause an inefficient usage of power supply.
Table 4: Main supported features of the SARA-U2 series
u-blox is extremely mindful of user privacy. When a position is sent to the CellLocate® server, u-blox is
unable to track the SIM or the specific device that sent the position.

SARA-U2 series - Data Sheet
2 Interfaces
2.1 Power management
2.1.1 Module supply (VCC)
SARA-U2 modules must be supplied through the 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 SARA-G3 and SARA-U2 series System Integration
Manual [6]). It is important that the system power supply circuit is able to support peak power.
2.1.2 RTC supply (V_BCKP)
V_BCKP is the Real Time Clock (RTC) supply of SARA-U2 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 Generic digital interfaces supply (V_INT)
SARA-U2 modules provide a 1.8 V supply rail output on the V_INT pin, which is internally generated when the
module is switched on. The same voltage domain is used internally to supply the generic digital interfaces of the
modules. The V_INT supply output can be used in place of an external discrete regulator optimizing the bill of
material for various applications, e.g. with u-blox GNSS receivers 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-U2 modules.
2.2.2 Antenna detection (ANT_DET)
The ANT_DET pin is an Analog to Digital Converter (ADC) input 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 and SARA-U2 series System
Integration Manual [6] and the u-blox AT Commands Manual [4], +UANTR).
2.3 System functions
2.3.1 Module power-on
SARA-U2 modules can be switched on in one of the following ways:
Rising edge on VCC pins to a valid voltage for module supply, i.e. applying module supply
Low pulse on PWR_ON pin, i.e. forcing the pin (normally high with external pull-up) to a low level for a valid
time period (see section 4.2.6): PWR_ON pin requires an external pull-up resistor to set its value to logic
high and may not be left floating
Rising edge on RESET_N pin, i.e. releasing the pin from the low level, normally high with internal pull-up
RTC alarm, i.e. pre-programmed scheduled time by AT+CALA command
UBX-13005287 - R17
Interfaces
Page 11 of 57
SARA-U2 series - Data Sheet
2.3.2 Module power-off
SARA-U2 modules can be properly switched off, with storage of current parameter settings and network detach,
in one of these ways:
AT+CPWROFF command
Low pulse on the PWR_ON pin for at least 1 s
An abrupt under-voltage shutdown occurs on SARA-U2 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-U2 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 and
SARA-U2 series System Integration Manual [6] and u-blox AT commands manual [4], +USTS AT command.
2.3.3 Module reset
SARA-U2 modules can be properly reset (rebooted), with storage of current parameter settings and network
detach, in this way:
By the AT+CFUN command (see the u-blox AT Commands Manual [4]). This causes an “internal” or
“software” reset of the baseband processor, excluding the integrated power management unit and the RTC
internal block: the V_INT generic digital interfaces supply is enabled and each digital pin is set to its internal
reset state (reported in Table 6), the V_BCKP supply and the RTC block are enabled.
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 4.2.7). This causes a reset of the
entire module, including the integrated power management unit, except for the RTC internal block: the V_INT
generic digital interfaces supply is switched off and all the digital pins are tri-stated, but the V_BCKP supply and
the RTC block are enabled. The current parameter settings are not saved in the module’s non-volatile memory
and a proper network detach is not performed.
2.4 SIM
2.4.1 (U)SIM interface
SARA-U2 modules provide a (U)SIM interface on the VSIM, SIM_IO, SIM_CLK, SIM_RST pins: the high-speed
SIM/ME interface is implemented as well as automatic detection of the required SIM supporting voltage.
Both 1.8 V and 3 V SIM card/chip types are supported (1.8 V and 3 V ME). Activation and deactivation with
automatic voltage switch from 1.8 V to 3 V is implemented, according to ISO-IEC 7816-3 specifications. The SIM
driver supports the PPS (Protocol and Parameter Selection) procedure for baud-rate selection, according to the
values proposed by the SIM card/chip.
2.4.2 SIM card detection (SIM_DET)
The SIM_DET pin of SARA-U2 modules is a 1.8 V digital input which is by default configured as an external
interrupt to detect the SIM card presence (as a feature which can be optionally used) when it is properly
connected to the mechanical switch of the SIM card holder (for more details see SARA-G3 and SARA-U2 series
System Integration Manual [6]).
The SIM_DET pin of SARA-U2 modules can additionally be configured via AT command to provide the “SIM
card hot insertion/removal” function (for more details see u-blox AT Commands Manual [4], +UDCONF=50).
The SIM_DET pin of SARA-U2 modules can additionally be configured via AT command as GPIO (for more
details see section 2.7 and the u-blox AT Commands Manual [4], +UGPIOC, +UGPIOR, +UGPIOW).

4 Electrical specifications
Stressing the device above one or more of the ratings listed in the Absolute Maximum Rating
section may cause permanent damage. These are stress ratings only. Operating the module at
these or at any conditions other than those specified in the Operating Conditions sections
(section 4.2) of the specification should be avoided. Exposure to Absolute Maximum Rating
conditions for extended periods may affect device reliability.
Operating conditions ranges define those limits within which the functionality of the device is guaranteed.
Where application information is given, it is advisory only and does not form part of the specification.

7.2 Moisture Sensitivity Levels
SARA-U2 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-U2
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 [16].
For MSL standard see IPC/JEDEC J-STD-020 (can be downloaded from http://www.jedec.org/).
7.3 Reflow soldering
Reflow profiles are to be selected according to u-blox recommendations (see SARA-G3 and SARA-U2 series
System Integration Manual [6]).
Failure to observe these recommendations can result in severe damage to the device!
7.4 ESD precautions
SARA-U2 modules contain highly sensitive electronic circuitry and are Electrostatic Sensitive
Devices (ESD). Handling SARA-U2 modules without proper ESD protection may destroy or
damage them permanently.
SARA-U2 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-U2 module.
Proper ESD handling and packaging procedures must be applied throughout the processing, handling and
operation of any application that incorporates SARA-U2 module.
ESD precautions should be implemented on the application board where the module is mounted, as described in
SARA-G3 and SARA-U2 series System Integration Manual [6].
Failure to observe these precautions can result in severe damage to the device!
