SARA-N2 series - Data Sheet

1 Functional description

1.1 Overview

SARA-N2 series modules are a Narrow Band Internet of Things (NB-IoT) solution coming in the

miniature SARA LGA form factor (16.0 x 26.0 mm, 96-pin). The modules offer IoT data communication

over an extended operating temperature range of –40 °C to +85 °C, with extremely low power

consumption.

The SARA-N2 series includes variants supporting single-band and dual-band communication and

designed to operate in the frequency range of the LTE bands 5, 8, 20 and 28. These products are

ideally suited to battery-powered IoT applications characterized by occasional communications of

small amounts of data.

SARA-N2 series modules are the optimal choice for IoT devices designed to operate in locations with

a very limited coverage and requiring low energy consumption to permit a very long operating life of

the primary batteries. Examples of applications include and are not limited to: smart grids, smart

metering, telematics, street lighting, environmental monitoring and control, security and asset

tracking.

1.5 AT command support

The SARA-N2 series modules support AT commands according to the 3GPP standards, plus the

u-blox AT command extensions.

☞

For the complete list of all supported AT commands and their syntax, see the SARA-N2 series AT

Commands Manual [1].

1.6 Supported features

Feature

Description

Network Indication

Pin configured to indicate the network status: registered home network, registered roaming,

data call enabled, no service. The feature can be enabled through the +UGPIOC AT command.

Embedded UDP stack

CoAP

Embedded UDP/IP stack for UDP sockets.to establish a transparent end-to-end communication.

The Constrained Application Protocol (CoAP) is a datagram-based client/server application

protocol for devices on the constrained network (e.g. low overhead, low-power), designed to

easily translate to HTTP for simplified integration with the web. CoAP clients can use the GET,

PUT, POST and DELETE methods using requests and responses with a CoAP server.

Release Assistance

Self-Registration

The Release Assistance feature introduced in 3GPP Rel.13 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.

Support of Self-Registration feature according to CTCC (China Telecom Corporation) and CUCC

(China Unicom Corporation) requirements.

Firmware update Over AT

commands (FOAT)

Firmware module update over AT command interface.

The feature can be enabled and configured through the +UFWUPD AT command.

Firmware update Over The The Firmware over-the-air (FOTA) component uses the CoAP context to download a FW update

Air (FOTA) package from a dedicated server.

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 extremely

low power deep sleep mode during periods of data inactivity. It can be activated and configured

by the +CPSMS AT command.

Deep-sleep mode

The SARA-N2 series modules enters in extremely low power deep sleep mode whenever

possible, using the internal 32 kHz clock to maintaining an extremely low current consumption.

This optimizes the life time of the battery pack used to supply the system

eDRX

Extended 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. This in turn leads to a reduction in the module power consumption while maintaining a

perpetual connection with the base station

Coverage Enhancement

Coverage Enhancements Modes introduced in 3GPP Rel.13 for the NB-IoT system improve the

cell signal penetration allowing a 20 dB coverage enhancement over standard GSM systems.

SARA-N2 series - Data Sheet

2 Interfaces

2.1 Power management

2.1.1 Module supply input (VCC)

SARA-N2 series modules must be supplied through the VCC pins by a DC power supply with nominal

voltage of 3.6 V. Voltage must be stable during module operation, taking into account that the current

drawn from VCC pins may vary significantly based on the power consumption profile of the NB-IoT

system.

2.1.2 Digital I/O interfaces supply output (V_INT)

SARA-N2 series modules provide an internally generated supply rail output (V_INT) operating at 1.8 V.

This can be used in place of an external discrete regulator to supply external digital interfaces.

The voltage level present at the V_INT pin depends on the module operating mode:



When the radio is off, the voltage level is kept low (i.e. 0 V)

When the radio is on, the voltage level is maintained high (i.e. 1.8 V)

☞

Provide a test point connected to the V_INT pin for diagnostic purpose.

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-N2 series

modules.

2.2.1.1 Antenna detection (ANT_DET)

The ANT_DET pin is an Analog to Digital Converter (ADC) input used to sense the antenna presence

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 (ANT_DET) interface is not supported by "02" product versions.

2.3 System functions

2.3.1 Module power-on

SARA-N2 series modules can be switched on by a rising edge voltage applied to the VCC pins. See

section 4.2.2 for more details about the valid supply voltage range.

2.3.2 Module power-off

An abrupt under-voltage shutdown occurs on SARA-N2 series modules when the VCC supply voltage

drops below the operating range minimum limit (see section 4.2.2).

2.3.3 Module reset

SARA-N2 series modules can be reset applying a low voltage level on the RESET_N input pin, which is

normally set high by an internal pull-up, for a valid time period (see the section 4.2.5). This causes an

“external” or “hardware” reset of the module.

☞

Provide a test point connected to the RESET_N pin for diagnostic purposes.

UBX-15025564 - R16

Interfaces

Page 8 of 30

SARA-N2 series - Data Sheet

2.4 SIM interface

A SIM card interface is provided by the VSIM, SIM_IO, SIM_CLK, and SIM_RST pins of SARA-N2 series

modules, supporting 1.8 V SIM card/chip types.

2.5 Serial interfaces

2.5.1 Asynchronous serial interface (UART)

The UART interface is a 5-wire unbalanced asynchronous serial interface available for communication

with an application host processor (AT commands and data communication) and for FW upgrade.

The main characteristics of the interface are the following:



Serial port with RS-232 functionality working at the VCC voltage domain (0 V for low data bit or

ON state and ~3.6 V, i.e. VCC, for high data bit or OFF state)



Data lines (RXD as module data output, TXD as module data input)

Hardware flow control lines (CTS as module output, RTS as module input)

The following baud rates are supported: 4800, 9600 (default baud rate), 57600 and 115200 b/s.

Fixed frame format: 8N1 (8 data bits, no parity, 1 stop bit)

The CTS line can be configured as RING indicator, to signal an incoming message received by the

module or an URC event, or as Network status indicator (for more details see section 2.6 and the u-blox

SARA-N2 series AT Commands Manual [1], +URING, +UGPIOC AT commands).

☞

For FW upgrade purposes, connect a test point to the RXD and TXD pins.

Hardware flow control function is not supported by the "02" product versions.

2.5.2 Secondary asynchronous serial interface (Secondary UART)

The secondary UART interface is a 2-wire unbalanced asynchronous serial interface available for

diagnostic purpose, to capture trace diagnostic logs delivered by the module.

The main characteristics of the interface are:



Serial port with RS-232 functionality working at the V_INT voltage domain (0 V for low data bit or

ON state and 1.8 V, i.e. V_INT, for high data bit or OFF state)

Data line (GPIO1 as module data output)

No flow control

Fixed baud rate: 921600 b/s



Fixed frame format: 8N1 (8 data bits, no parity, 1 stop bit)

☞

For diagnostic purposes, connect a test point to the GPIO1 pin.

The trace diagnostic log is temporarily stopped when the module is in deep-sleep mode.

SARA-N2 series - Data Sheet

2.5.3 DDC (I²C) interface

DDC interface: I²C compatible interface available on the SCL and SDA pins of the module for the

communication with external chips and sensors. The interface provides master mode bi-directional

bus communication at a bit-rate up to 100 kb/s. The I²C interface requires external pull-up resistors.

The internal power domain used by the DDC (I²C) pins is V_INT (1.8 V).

☞

The DDC (I²C) interface is not supported by "02" product versions.

2.6 GPIO

SARA-N2 series modules provide the following pins:



GPIO1 pin, working at the V_INT (1.8 V) voltage domain, supporting the Secondary UART data

output functionality (see section 2.5.2 and Table 4)



GPIO2 pin, working at the V_INT (1.8 V) voltage domain, not supported by "02" product versions

CTS pin, working at the VCC (3.6 V typical) voltage domain, supporting the Network status

indication and the RING indicator functionality (see section 2.5.1 and Table 4)

For more details about how the pins can be configured, see u-blox SARA-N2 series AT Commands

Manual [1], +UGPIOC, +URING AT commands.

SIQ 18 ATEX 104 U

SARA-N211 modules certification number according to the IECEx conformity assessment system:

IECEx SIQ 18.0004U

According to the standards listed above, SARA-N211 modules are certified with following marking:

Ex II 1G, Ex ia IIC

According to the marking stated above, the 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’: 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 for SARA-N211 modules.

The RF radiating profile of SARA-N211 modules is compliant to all the applicable 3GPP / ETSI

standards, with a maximum of 250 mW RF average power according to the LTE Cat NB1 Power Class

stated in Table 2. Section 8.1 describes the nameplate of SARA-N211 modules (see Figure 8).

7.2 Moisture Sensitivity Levels

⚠

SARA-N2 series modules are Moisture Sensitive Devices (MSD) in accordance to IPC/JEDEC

specification

The Moisture Sensitivity Level (MSL) relates to the packaging and handling precautions required.

SARA-N2 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 [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-N2 series

System Integration Manual [2]).

⚠

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

7.4 ESD precautions

SARA-N2 series modules contain highly sensitive electronic circuitry and are Electrostatic

Sensitive Devices (ESD). Handling SARA-N2 series modules without proper ESD protection may

destroy or damage them permanently.

SARA-N2 series modules are Electrostatic Sensitive Devices (ESD) and require special ESD

precautions typically applied to ESD sensitive components.

Table 7 reports the maximum ESD ratings of the SARA-N2 series modules.

Proper ESD handling and packaging procedures must be applied throughout the processing, handling

and operation of any application that incorporates SARA-N2 series module.

ESD precautions should be implemented on the application board where the module is mounted, as

described in the SARA-N2 series System Integration Manual [2].

⚠

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