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 fa ctor 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 t emperature 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 ma nagement, 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 cellu lar 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 p ick & place and reflow soldering equipment for cost-efficient, high-volume production.

1.6 Supported features

Table 4 lists the main features supported by SARA-U2 modules. For more details see the SARA-G3 and SARA-U2 series System Integration Manual [6] and u-blox AT commands manual [4]. Feature Description Network indication GPIO configured to indicate the network status: registered home network, registered roaming, voice or data call enabled, no service. The feature can be enabled through the +UGPIOC AT command. Antenna detection The ANT_DET pin provides antenna presence detection capability, evaluating the resistance from the ANT pin to GND by means of an external antenna detection circuit implemented on the application board. The antenna detection feature can be enabled through the +UANTR AT command. All these functionalities are supported via AT commands (for more details see u-blox AT Commands Manual [4]).

SARA-U2 series - Data Sheet UBX-13005287 - R17 Functional description Page 9 of 57 Feature Description Jamming detection Detects some “artificial” interference that obscures the operator’s carriers entitled to give access to the GSM/UMTS service and reports the start and stop of such conditions to the application processor (AP). The AP can react appropriately by e.g. switching off the radio transceiver to reduce power consumption and monitoring the environment at constant periods. The feature can be enabled and configured through the +UCD AT command. Embedded TCP and UDP stack Embedded TCP/IP and UDP/IP stack including direct link mode for TCP and UDP sockets. Sockets can be set in Direct Link mode to establish a transparent end to end communication with an already connected TCP or UDP socket via serial interface. FTP, FTPS 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 1.2 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 Capability to move between IPv4 and dual stack network infrastructures using external context. IPv4 and IPv6 addresses can be used. GNSS via modem Full access to u-blox positioning chips and modules is available through a dedicated DDC (I C) 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 / LCS 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 SAP Server directly connected to the remote SIM. The modules provide a dedicated USB SAP channel and a dedicated multiplexer SAP channel over UART for communication with the remote (U)SIM card. The feature can be configured and enabled by +USAPMODE and + USAPIND AT commands. BIP Bearer Independent Protocol for Over-the-Air SIM provisioning. The data transfer to/from the SIM uses either an already active PDP context or a new PDP context established with the APN provided by the SIM card.

SARA-U2 series - Data Sheet UBX-13005287 - R17 Functional description Page 10 of 57 Feature Description In-Band Modem 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 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. Power saving 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 type 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 calls The quality of the GPRS UL and/or DL connection is returned by the AT+CSQ command. eMLPP 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 Mode 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 interface 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. ODIS 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 gasp 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) 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) 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 i s sent to the CellLocate server, u-blox is unable to track the SIM or the specific device that sent the position.

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 generi c 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

SARA-U2 series - Data Sheet UBX-13005287 - R17 Interfaces Page 12 of 57

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 occ urs 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 inte rnal 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).

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, st orage 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 ES D 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!
