1 Functional description

1.1 Overview

The SARA-R4 series modules are a multi-band LTE-M / NB-IoT / EGPRS multi-mode solution in the miniature SARA LGA form factor (26.0 x 16.0 mm, 96-pin). They allow an easy integration into compact designs and a seamless drop-in migration from other u-blox cellular module families.

SARA-R4 series modules provide software-based multi-band configurability enabling international multi-regional coverage in LTE-M / NB-IoT and (E)GPRS radio access technologies.

SARA-R4 series modules offer data communications over an extended operating temperature range of –40 °C to +85 °C, with low power consumption, and with coverage enhancement for deeper range into buildings and basements (and underground with NB-IoT).

SARA-R4 series modules are form-factor compatible with the u-blox LISA, LARA and TOBY cellular module families and are pin-to-pin compatible with the u-blox SARA-N, SARA-G and SARA-U cellular module families. This facilitates migration from other u-blox LPWA, GSM/GPRS, CDMA, UMTS/HSPA and higher LTE categories modules, maximizing customer investments, simplifying logistics, and enabling very short time-to-market.

With many interface options and an integrated IP stack, SARA-R4 series modules are the optimal choice for LPWA applications with low to medium data throughput rates, as well as devices that require long battery lifetimes, such as used in smart metering, smart lighting, telematics, asset tracking, remote monitoring, alarm panels, and connected health.

Secure cloud product versions are available within the SARA-R4 series modules, including a unique and immutable root-of-trust. This provides the foundation for a trusted set of advanced security functionalities. The scalable, pre-shared key management system offers best-in-class data encryption and decryption, both on-device as well as from device-to-cloud. Utilizing the latest (D)TLS stack and cipher suites with hardware-based crypto acceleration provides robust, efficient, and protected communication.

Furthermore, the SARA-R422 series modules support a comprehensive set of 3GPP Rel. 14 features for LTE Cat M1 and Cat NB2 that are relevant for IoT applications.

The dedicated SARA-R422M8S module is pre-integrated with the u-blox M8 GNSS receiver chip and a separate GNSS antenna interface which provides highly reliable, accurate positioning data simultaneously with LTE communication. In addition, the module offers unique hybrid positioning, in which the GNSS position is enhanced with u-blox CellLocate® data, providing location always and everywhere.

Customers can future-proof their solutions by means of Over-The-Air firmware updates, thanks to the uFOTA client/server solution that utilizes LWM2M, a light and compact protocol ideal for IoT.

SARA-R4 series modules will also support VoLTE over Cat M1 and CSFB over 2G. The flexibility extends further through dynamic mode selection as M1-only/preferred or NB-IoT-only/preferred.

Feature

Description

Integrated GNSS receiver 13

SARA-R422M8S modules are pre-integrated with a u-blox M8 GNSS receiver chip-down design, comprehensive of a dedicated GNSS antenna interface, LNA and SAW filter for a highly reliable, accurate positioning data.

The GNSS system is totally independent from the LTE system and can run concurrently to a LTE communication.

External GNSS access and control via modem 14

Full access to external u-blox positioning chips and modules is available through I2C interface. This means that from any host processor, a single serial port can control the SARA-R4 series cellular module and the separated u-blox positioning chip or module.

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. CellLocate® is available via a set of AT commands for CellLocate® service configuration and position request.

Power Saving Mode (PSM)

The Power Saving Mode (PSM) feature, defined in 3GPP Rel.13, allows further reduction of the module current consumption maximizing the amount of time a device can remain in PSM low power deep sleep mode during periods of data inactivity. It can be activated and configured by the +CPSMS AT command.

e-I-DRX 16

Extended Idle mode DRX, based on 3GPP Rel.13, reduces the amount of signaling overhead decreasing the frequency of scheduled measurements and/or transmissions performed by the module in idle mode. This in turn leads to a reduction in the module power consumption while maintaining a perpetual connection with the base station.

Coverage Enhancements Mode A

Coverage Enhancements (CE) Mode A, introduced in 3GPP Rel.13, is used to improve cell signal penetration.

Coverage Enhancements Mode B 17

Coverage Enhancements (CE) Mode B, introduced in 3GPP Rel.13, is used to further improve cell signal penetration.

Connected Mode Mobility 18

LTE Cat M1 Connected Mode Mobility (CMM) with CE Mode A

Release Assistance Indicator 18

The 3GPP Release Assistance feature allows the module to request for the RRC connection to be dropped as soon as the message has been received by the network. This feature allows a reduction in the module power consumption.

LwM2M with dynamically loaded objects 19

Method allowing dynamically loaded run time objects for customers to configure u-blox modules to define necessary objects, create instances of those objects as appropriate, manage module LwM2M protocol stack to interact with the LwM2M server.

Backup and restore 20 21

This feature allows the modules to autonomously restore the flash file system using the last backup stored on the module itself. For further details about the backup and restore feature, see the +UBKUPDATA AT command description in the SARA-R4 series AT commands manual [1], and the backup and restore technical note [5].

Table 3: Some of the main features supported by SARA-R4 series modules

☞ 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 used or the specific device.

UBX-16024152 - R24 Interfaces Page 13 of 48 C1-Public

2 Interfaces

2.1 Power management

2.1.1 Module supply input (VCC)

SARA-R4 series modules must be supplied through the VCC pins by a DC power supply. Voltage must be stable, because during operation the current drawn from VCC may vary significantly, based on the power consumption profile of the LTE-M, NB-IoT and the 2G radio access technologies (described in the SARA-R4 series system integration manual [2]).

SARA-R412M, SARA-R422, SARA-R422S, and SARA-R422M8S modules, which support 2G radio access technology, 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 call

• VCC pin #51 represents the supply input for the internal baseband Power Management Unit,

demanding minor part of the total current drawn of the module when RF transmission is enabled during a call

The three VCC pins of the SARA-R410M modules are internally connected to both the internal Power Amplifier and the internal baseband Power Management Unit.

It is important that the system power supply circuit is able to withstand the maximum pulse current during a transmit burst at maximum power level (see Table 12).

2.1.2 Generic digital interfaces supply output (V_INT)

SARA-R4 series 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 module. The V_INT supply output can be used in place of an external discrete regulator.

2.2 Antenna interface

2.2.1 Cellular antenna RF interface (ANT)

The ANT pin is the cellular RF antenna I/O interface, designed with 50  characteristic impedance.

2.2.2 GNSS antenna RF interface (ANT_GNSS)

☞ The GNSS antenna RF interface is not supported by SARA-R410M, SARA-R412M, SARA-R422, or

SARA-R422S modules.

The ANT_GNSS pin represents the GNSS RF input of the SARA-R422M8S modules, designed with 50  characteristic impedance and with an internal DC block, suitable for both active and/or passive GNSS antennas due to the built-in SAW filter followed by an LNA in front of the integrated high performing u-blox M8 concurrent positioning engine.

2.2.3 Antenna detection (ANT_DET)

The ANT_DET pin is an Analog to Digital Converter (ADC) input with a current source provided by SARA-R4 series modules to sense the antenna presence (as an optional feature). It evaluates 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 u-blox SARA-R4 series system integration manual [2] and the SARA-R4 series AT commands manual [1]).

SARA-R4 series - Data sheet

UBX-16024152 - R24 Interfaces Page 14 of 48 C1-Public

2.3 System functions

2.3.1 Module power-on

SARA-R4 series modules can be properly switched on by:

• Low level on the PWR_ON pin, which is normally set high by an internal pull-up, for a valid time

period, when the applied VCC voltage is within the valid operating range (see sections 4.2.3, 4.2.9). The PWR_ON line has to be driven by open drain, open collector or contact switch.

• Low level on the PWR_CTRL pin, which is normally set high by an internal pull-up, for a valid time

period, when the applied VCC voltage is within the valid operating range (see sections 4.2.3,

4.2.10). The PWR_CTRL line has to be driven by open drain, open collector or contact switch.

2.3.2 Module power-off

SARA-R4 series modules can be properly switched off, with storage of the current parameter settings in the module’s internal non-volatile memory and a clean network detach, in one of these ways:

• AT+CPWROFF command (see the SARA-R4 series AT commands manual [1])

• Low pulse on the PWR_ON pin for a valid time period (see section 4.2.9)

• Low pulse on the PWR_CTRL pin for a valid time period (see section 4.2.10)

An emergency faster and safe power-off procedure of SARA-R422, SARA-R422S, SARA-R422M8S modules, without proper network detach, can be triggered by:

• AT+CFUN=10 command (see the SARA-R4 series AT commands manual [1])

• Toggling the GPIO input pin configured with the fast and safe power-off function (see section 2.7)

An abrupt shutdown occurs on SARA-R4 series modules, without storage of the current parameter settings and without a clean network detach, when:

• The VCC supply drops below the extended operating range minimum limit

• Low level on the RESET_N pin, which is normally set high by an internal pull-up, for a valid time

period (see 4.2.11). RESET_N line has to be driven by open drain, open collector or contact switch.

2.3.3 Module reset

SARA-R4 series modules can be reset (re-booted) by:

• AT+CFUN=15 command (see the SARA-R4 series AT commands manual [1] for detailed options).

This causes an “internal” or “software” reset of the module. The current parameter settings are

saved in the module’s internal non-volatile memory and a clean network detach is performed.

An abrupt emergency reset (reboot) is triggered on the SARA-R422, SARA-R422S, SARA-R422M8S modules, without storage of current parameter settings and without a clean network detach, when:

• a low level is applied on the PWR_CTRL pin for a valid time period (see section 4.2.10)

2.4 SIM

2.4.1 SIM interface

SARA-R4 series modules provide a SIM interface on the VSIM, SIM_IO, SIM_CLK, SIM_RST pins to connect an external SIM card or UICC chip.

SARA-R410M and SARA-R412M modules support both 1.8 V and 3.0 V types of SIM / UICC, with automatic voltage switch implemented according to related specifications.

SARA-R422, SARA-R422S and SARA-R422M8S modules support only the 1.8 V type of SIM / UICC.

SARA-R4 series - Data sheet

UBX-16024152 - R24 Interfaces Page 15 of 48 C1-Public

2.4.2 SIM detection

The GPIO5 pin of SARA-R4 series modules is a 1.8 V digital input which can be configured as an external interrupt to detect the SIM card presence, as intended to be properly connected to the mechanical switch of an external SIM card holder. For more details, see the SARA-R4 series system integration manual [2] and the SARA-R4 series AT commands manual [1].

2.5 Serial communication

• UART interfaces: asynchronous serial interface available for the communication with a DTE host

application processor (AT commands, data communication, FW update by means of FOAT)

• USB interface: High-Speed USB 2.0 compliant interface available for communications with a USB

host application processor (AT commands22, data communication22, FW update by means of the FOAT feature22), for FW update by means of the u-blox tool and for diagnostics

devices

2.5.1 UART interfaces

SARA-R4 series modules include a primary UART interface (UART) for communication with an application host processor, supporting AT commands, data communication, multiplexer protocol functionality, FW update by means of FOAT, with settings configurable by dedicated AT commands (for more details, see the SARA-R4 series AT commands manual [1]):

• 8-wire serial port with RS-232 functionality conforming to ITU-T V.24 recommendation [11], with

CMOS compatible signal levels (0 V for low data bit / ON state, 1.8 V for high data bit / OFF state)

o Data lines (RXD as data output, TXD as data input) o HW flow control lines (CTS as flow control output, RTS as flow control input) o Modem status and control lines (DTR input, DSR output, DCD output, RI output)

• The default baud rate is 115200 b/s

• The default frame format is 8N1 (8 data bits, no parity, 1 stop bit)

☞ The UART is available only if the USB is not enabled as an AT command / data communication

interface: UART and USB cannot be concurrently used for this purpose.

☞ Hardware flow control is not supported by the SARA-R410M-01B or the SARA-R410M-02B-00

product versions, and the RTS input line needs to be set low (= ON state) to communicate over the UART on the SARA-R410M-01B product version.

SARA-R422, SARA-R422S, SARA-R422M8S modules include a secondary auxiliary UART interface (UART AUX) for communication with an application host processor, supporting AT commands, data communication, GNSS tunneling25, FW update by means of FOAT, with settings configurable by dedicated AT commands (for more details, see the SARA-R4 series AT commands manual [1]):

CMOS compatible signal levels (0 V for low data bit / ON state, 1.8 V for high data bit / OFF state)

Not supported by SARA-R422-00B, SARA-R422S-00B or SARA-R422M8S-00B modules

Not supported by the current product versions of SARA-R410M and SARA-R412M modules. Not available on SARA-R422, SARA-R422S and SARA-R422M8S modules.

DTR, DSR, DCD and RI pins can be alternatively configured, in a mutually exclusive way, as secondary auxiliary UART interface (UART AUX) on SARA-R422, SARA-R422S and SARA-R422M8S modules.

Not supported by SARA-R422-00B modules

SARA-R4 series - Data sheet

UBX-16024152 - R24 Interfaces Page 16 of 48 C1-Public

o Data lines (DCD as data output, DTR as data input) o HW flow control lines (RI as flow control output, DSR as flow control input)

• The default baud rate is 115200 b/s

• The default frame format is 8N1 (8 data bits, no parity, 1 stop bit)

2.5.1.1 Multiplexer protocol

SARA-R4 series modules include multiplexer functionality as per 3GPP TS 27.010 [8] on the primary UART physical link. This is a data link protocol which uses HDLC-like framing and operates between the module (DCE) and the application processor (DTE), allowing simultaneous sessions over the primary UART physical link.

The following virtual channels are defined:

• Channel 0:

for multiplexer control

• Channel 1:

for all AT commands, and non-Dial Up Network (non-DUN) data connections. UDP, TCP data socket / data call connections through relevant AT commands.

• Channel 2:

for Dial Up Network (DUN) data connection. It requires the host to have and use its own TCP/IP stack. The DUN can be initiated on the modem side or terminal/host side.

• Channel 3:

for u-blox GNSS data tunneling (not supported by SARA-R410M-01B or SARA-R422-00B product versions).

2.5.2 USB interface

SARA-R4 series modules include a high-speed USB 2.0 compliant interface with a maximum 480 Mb/s data rate according to the USB 2.0 specification [12]. The module itself acts as a USB device and can be connected to any USB host equipped with compatible drivers.

The USB is the most suitable interface for transferring high speed data between the SARA-R410M and SARA-R412M modules and an external host processor, available for AT and data communication, FW upgrade by means of the FOAT feature.

The USB is the interface of SARA-R4 series modules available for FW upgrade by means of the u-blox dedicated tool and for diagnostic purposes.

SARA-R410M and SARA-R412M modules provide the following USB lines:

• the USB_D+ / USB_D- lines, carrying the USB data and signaling

• the VUSB_DET input pin to enable the USB interface by applying an external voltage (5.0 V typical)

SARA-R422, SARA-R422S and SARA-R422M8S modules provide the following USB lines:

• the USB_D+ / USB_D- lines, carrying the USB data and signaling

• the USB_5V0 input pin to enable the USB interface by applying an external voltage (5.0 V typical)

• the USB_3V3 input pin to supply the USB interface by applying an external 3.3 V typical voltage

• the RSVD #33 pin to be externally accessible to enable FW upgrade over the USB interface

☞ The USB interface is available as an AT / data communication interface on the SARA-R410M and

SARA-R412M modules only if an external valid USB VBUS voltage (5.0 V typical) is applied at the VUSB_DET input of the module since the switch-on of the module, and then held during normal operations. In this case, the UART will not be available.

☞ AT commands and data communication are not supported via USB interface on SARA-R422-00B,

SARA-R422S-00B or SARA-R422M8S-00B product versions: the USB interface is available on these product versions only for firmware upgrade by means of the u-blox dedicated tool and for diagnostic purposes.

☞ If the USB interface is enabled, the module does not enter the low power deep sleep mode: the

external voltage needs to be removed from the VUSB_DET / USB_5V0 and USB_3V3 input pins of the module to let it enter the Power Saving Mode defined in 3GPP Rel.13.

SARA-R4 series - Data sheet

UBX-16024152 - R24 Interfaces Page 17 of 48 C1-Public

☞ It is highly recommended to provide access to the V_INT, PWR_ON / PWR_CTRL, VUSB_DET /

USB_5V0, USB_3V3, USB_D+, USB_D-, RSVD #33 pins for FW update and for diagnostic purpose,

by means of test points directly connected to the pins, or by dedicated connector / circuit.

SARA-R410M and SARA-R412M modules provide two USB functions:

• AT commands and data communication

• Diagnostic log

SARA-R422, SARA-R422S and SARA-R422M8S modules provide the following USB function:

with a compatible external device.

2.5.4 SDIO interface

☞ The SDIO interface is not supported by current product versions.

SARA-R410M and SARA-R412M modules include a 4-bit secure digital input output (SDIO) interface (SDIO_D0, SDIO_D1, SDIO_D2, SDIO_D3, SDIO_CLK, and SDIO_CMD) designed to communicate with external compatible SDIO devices.

2.5.5 DDC (I2C) interface

☞ The DDC (I2C) interface is not supported by SARA-R410M-01B product versions.

SARA-R4 series modules include an I2C-bus compatible DDC interface (SDA, SCL) available to communicate with an external u-blox GNSS receiver26 and with external I2C devices as for example an audio codec: the SARA-R4 series module acts as an I2C host that can communicate with I2C local devices in accordance with the I2C-bus specifications [13].

The SDA and SCL pins have internal pull-up to V_INT, so there is no need of additional pull-up resistors on the external application board.

2.6 Audio

☞ Audio is not supported by current product versions.

An I2S digital audio interface is included to transfer audio data to/from an external audio device, with the aim of providing Voice over LTE Cat M1 radio bearer (VoLTE) services and CSFB over 2G RAT.

4.3 Parameters for ATEX applications

This section provides useful parameters and information to integrate SARA-R4 series modules in applications intended for use in areas with potentially explosive atmospheres (ATEX), describing:

• Total internal capacitance and inductance of the modules (see Table 29)

• Maximum RF output power at the antenna (ANT) pin of the modules (see Table 30)

☞ Any specific applicable requirement for the implementation of the apparatus integrating the

SARA-R4 series modules, intended for use in potentially explosive atmospheres, must be fulfilled according to the exact applicable standards: check the detailed requisites on the pertinent normative for the application, as for example the IEC 60079-0 [14], IEC 60079-11 [15], and IEC 60079-26 [16] standards.

☞ The certification of the application device that integrates a SARA-R4 series module and the

compliance of the application device with all the applicable certification schemes, directives and standards required for use in potentially explosive atmospheres are the sole responsibility of the application device manufacturer.

Table 29 describes the maximum total internal capacitance and the maximum total internal

inductance, considering internal parts tolerance, of the SARA-R4 series modules.

7.2 Moisture Sensitivity Levels

⚠ SARA-R4 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-R4 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 user guide [3].

☞ For the 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 the SARA-R4 series system integration manual [2]).

⚠ Failure to observe these recommendations can result in severe damage to the device!

7.4 ESD precautions

⚠ SARA-R4 series modules contain highly sensitive electronic circuitry and are Electrostatic

Sensitive Devices (ESD). Handling SARA-R4 series modules without proper ESD protection may destroy or damage them permanently.

SARA-R4 series modules are Electrostatic Sensitive Devices (ESD) and require special ESD precautions typically applied to ESD sensitive components.

Table 7 details the maximum ESD ratings of the SARA-R4 series modules.

Proper ESD handling and packaging procedures must be applied throughout the processing, handling and operation of any application that incorporates the SARA-R4 series module.

ESD precautions should be implemented on the application board where the module is mounted, as described in the SARA-R4 series system integration manual [2].

⚠ Failure to observe these recommendations can result in severe damage to the device!
